Mohs' method of micrographic surgery as treatment for recurrent basal cell carcinoma

OBJECTIVE: Evaluation of Mohs' micrographic surgery as treatment for recurrent basal cell carcinoma of the skin. DESIGN: Retrospective. SETTING: University Hospital Maastricht, the Netherlands. METHOD: In the period April 1992 to December 1995, 91 recurrent basal cell carcinomas (88 patients) were treated by Mohs' micrographic surgery. Medical records were analysed retrospectively with respect to different aspects. RESULTS: The mean age of the patients was 69 years. The recurrent basal cell carcinomas, with an mean diameter of 19.7 mm, were mainly localized on the nose and forehead. There were equal numbers of solid and morphea-like types of basal cell carcinomas. Most of these tumours had been treated by means of surgical excision in the past. The last treatment had taken place 3 years previously on average. Reconstruction was performed by means of primary closure, a graft or a flap. The mean follow-up period after Mohs' micrographic surgery was 12 months, in which one tumour recurred. CONCLUSION: Mohs' micrographic surgery is a surgical technique which provides the best prospect of total tumour removal together with maximal functional and cosmetic preservation. Mohs' micrographic surgery is of particular value for the treatment of recurrent basal cell carcinomas.     

CHILD syndrome with linear eruptions, hypopigmented bands, and verruciform xanthoma

The traditional rhomboid transposition flap has been widely used in reconstructive surgery. The authors have modified the original technique by eliminating the creation of the rhomboid defect and by directly transposing the flap into the original postexcisional defect. These changes allow maximum flexibility in flap design and minimize normal tissue loss. The authors retrospectively reviewed the charts of patients who underwent periocular reconstruction with flaps from 1990 through 1995. The authors selected those patients in whom the modified rhomboid flap was used. Functional and cosmetic results and complications were reviewed. Two hundred thirty-two patients were identified in whom 242 flaps were performed. The modified rhomboid flap was used in 101 patients (41.7%). Complications occurred in 23 patients (23%), 19 of whom (19%) were treated medically and four of whom (4%) required an additional surgical procedure. Cosmetic and functional results were classified as very good or excellent in 96 patients (96%). The use of a modified rhomboid flap in the reconstruction of the periocular area offers ample versatility in flap design and minimal normal tissue loss. Functional and cosmetic results are satisfactory in the vast majority of cases.     

Excision of selected skin tumours using Mohs' micrographic surgery with horizontal paraffin-embedded sections

Histological interpretation of frozen sections made during Mohs' micrographic surgery may be difficult, depending on the morphological and staining characteristics of the tumour and on the nature of the associated inflammatory infiltrate. We have employed an adaptation of micrographic surgery in which horizontal, formalin-fixed, paraffin-embedded sections were used to improve histological assessment in the excision of 18 non-melanoma skin tumours in which frozen sections had been or were likely to be unsatisfactory. We describe our experience of this method in the management of squamous cell carcinomas (11), extramammary Paget's disease (two), microcystic adnexal cell carcinomas (two), dermatofibrosarcoma protuberans (two), and primary cutaneous neuroendocrine carcinoma (Merkel cell carcinoma) (one). The use of horizontal paraffin-embedded sections lengthens the duration of the procedure but facilitates accurate assessment of histological sections in selected tumours.     

Adjuvant radiation after conservative surgery for early breast cancer. Local control and cosmetic outcome

Between 1980 and 1987, 115 patients with early breast cancer underwent conservative surgery and radiation therapy. Median follow-up from the date of surgery was 48 months. There was local recurrence in 5 of the 115 patients. Of this group, 67 patients were evaluable for cosmetic outcome. The overall cosmetic result was judged by a panel to be excellent or good in 61%, fair in 27%, and poor in 12%. Patients themselves found the cosmetic result to be excellent or good in 94%. Retraction of the inferior border of the breast, surface difference between both breasts, breast induration, scar retraction and telangiectasia correlated with the cosmetic score. Type of surgery, axillary irradiation, use of bolus, and length of follow-up all influenced the cosmetic outcome in a univariate analysis.     

Cost-effectiveness of transaxillary muscle-sparing same-day operative closure of patent ductus arteriosus

Transaxillary muscle-sparing patent ductus arteriosus closure performed as same-day surgery is described in 10 patients. This approach provides a superb cosmetic result while obviating the need for thoracostomy tube placement.     

Video-assisted thoracoscopic surgery (VATS). Endoscopic thoracoplasty technique

STUDY DESIGN: The study of two patients whose rib deformity was treated using a new endoscopic thoracoplasty technique is reported. OBJECTIVES: To report a new endoscopic thoracoplasty technique for the treatment of rib deformities associated with idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: Thoracoplasty has traditionally been performed as an open procedure, often necessitating additional incisions and/or tissue dissection. METHODS: Two children with significant rib humps associated with idiopathic scoliosis were treated with a new endoscopic thoracoplasty technique. RESULTS: Both children showed dramatic cosmetic improvement of their rib deformity. CONCLUSIONS: The indications for the use of video-assisted thoracoscopic surgery in the treatment of pediatric spinal deformity are expanding. We have extended our video-assisted thoracoscopic surgery repertoire to include endoscopic thoracoplasty for treatment of rib deformities associated with idiopathic scoliosis. The technique for endoscopic thoracoplasty is discussed, and illustrative cases are presented.     

Breast-conserving surgery and radiotherapy for early breast cancer

Breast conservation is not a commonly prescribed treatment option for breast cancer in Taiwan. We report 42 patients with 43 early-stage breast cancers who were treated with breast-conserving surgery and radiotherapy at the Koo Foundation Sun Yat-Sen Cancer Center from April 1990 to December 1994. Included in this study were 33 patients with stage I cancers and 10 with stage II. Breast-conserving surgery consisted of wide local excision and ipsilateral axillary lymph node dissection. Radiotherapy was given 2 to 6 weeks after surgery, with a dose of 46 to 50 Gy, 2 Gy per fraction per day, to the whole breast, and an additional 14 to 18 Gy to the original tumor site. Irradiation to the regional lymph nodes was not performed in patients with negative axillary lymph nodes. Sixteen out of 43 (37%) patients were treated with adjuvant chemotherapy. The local control rate 3 years after treatment was 97% and relapse-free survival was 91%. The cosmetic outcome in 41 treated breasts that were rendered relapse-free by conserving treatment were evaluated and graded by the physicians as excellent, good, fair or poor using a standardized scale. Forty breasts (98%) were scored as excellent or good for their cosmetic results. Breast-conserving surgery and radio-therapy offer Taiwanese women with early breast cancer excellent local control and a highly satisfactory cosmetic outcome.     

Management of malignant melanoma of the head and neck

A total of 91 patients with melanoma of the head and neck treated between 1973 and 1991 were studied prospectively with regard to prognostic features, treatment and outcome. Other than Breslow thickness, the only important prognostic feature was the less aggressive nature of lentigo maligna melanoma. A policy of selective excision margins, 1 cm for impalpable and 2 cm for palpable lesions, was found to be safe, although preliminary biopsy should be used if there is diagnostic uncertainty or where the expected extent of surgery entails a mutilating procedure. Local recurrence rates were not affected by the method of wound closure, which should be determined by the best functional and cosmetic outcome. These results support the trend against prophylactic neck dissection. Such dissection, when indicated for lesions of the face, pinna, anterior scalp and parotid area, should routinely include superficial parotidectomy. Uncontrolled symptomatic loco-regional recurrence is an uncommon complication that may occur despite radical primary surgery. The role of preoperative radiotherapy for high-risk melanoma in this situation warrants investigation.     

Use of octyl-2-cyanoacrylate for skin closure in facial plastic surgery

Octyl-2-cyanoacrylate is a long carbon chain cyanoacrylate derivative that is stronger and more pliable than its shorter chain derivatives. One hundred and eleven patients underwent elective surgical procedures by the same surgeon using either octyl-2-cyanoacrylate or sutures for skin closure at the University of Illinois at Chicago. Most patients underwent excision of benign skin lesions with a mean wound size of 112 mm3. Patients were randomized into either control (vertical mattress suture closure) or test groups (closure with octyl-2-cyanoacrylate). Surgical judgment was used to determine which wounds in each group required application of subcutaneous sutures to relieve tension and aid in skin edge eversion. Generally, full-thickness (through dermis) wounds larger than 1 cm3 required the use of subcutaneous sutures. The time required to close the epidermis with suture (mean, 3 minutes and 47 seconds) was about four times that of octyl-2-cyanoacrylate (mean, 55 seconds). Wounds were evaluated at 5 to 7 days for infection, wound dehiscence, or tissue reaction, and at 90 days using the modified Hollander wound evaluation scale. At 1 year, photographs of the wounds were evaluated by two facial plastic surgeons that graded the cosmetic outcome using a previously validated visual analog scale. There were no instances of wound dehiscence, hematoma, or infection in either group. Results of wound evaluation at 90 days determined by the modified Hollander scal revealed equivalent cosmetic results in both groups. Results of the visual analog scale ratings showed scores of 21.7 +/- 16.3 for the 49 patients treated with octyl-2-cyanoacrylate and 29.2 +/- 17.7 for the 51 control patients treated with sutures. The lower visual analog scale score represented a superior cosmetic outcome at 1 year with the octyl-2-cyanoacrylate as compared with sutures. This difference is statistically significant at p = 0.03. Additionally, patient satisfaction was very high in the group treated with octyl-2-cyanoacrylate.     

Penile orthoplasty using dermal grafts in the outpatient setting

OBJECTIVES: To review and evaluate our extensive outpatient experience in the use of dermal grafts for the correction of significant residual chordee in patients requiring penile orthoplasty. METHODS: The medical records of all patients requiring surgical correction for severe penile curvature over the past 5 years were reviewed. Among these, 51 patients were identified in whom dermal grafts were used to correct severe residual chordee. Of these patients, 41 had severe hypospadias, 9 had epispadias, and 1 had urethral atresia. Graft harvest and placement technique, any resulting complications, and parental satisfaction with cosmetic and functional results were all evaluated. RESULTS: The dermal grafts were harvested from the hairless skin of the inguinal area, using one of two techniques. All were used to fill a tunical defect created by incising the tunica at the point of maximal penile curvature. No complications or postoperative hospitalizations resulted from any of the orthoplasty procedures. At a mean follow-up of 27 months, all patients had excellent cosmetic and functional results. CONCLUSIONS: In patients with significant residual chordee, a dermal graft is our preferred method of penile orthoplasty. This technique provides a straight phallus with a very minimal complication rate, it can easily and successfully be performed as an outpatient procedure, and it has assured an excellent cosmetic and functional result.     

Repair of central upper lip (philtral) surgical defects with island pedicle flaps

BACKGROUND: Surgical defects of the central upper lip (philtrum) are a particularly difficult area to achieve satisfactory cosmetic and functional repair. Reconstruction of the central upper lip has been accomplished primarily through the use of side-to-side closure, bilateral advancement or rotation flap, and full-thickness graft. Repair may be complicated by distortion of the vermilion border, obliteration of the normal contour of the philtrum, eclabium, and trapdooring of the flap. OBJECTIVE: We review the options for reconstruction of this area and describe our experience using an island pedicle flap to complete reconstruction. METHODS: Four patients presented with basal cell carcinomas of the mid upper lip (philtrum). Tumors were cleared by Mohs micrographic surgery. Reconstruction was achieved by island pedicle flaps utilizing donor tissue from the superior philtrum. RESULTS: The patients had excellent cosmetic results with minimal distortion of the vermilion border or obliteration of the philtrum or philtral ridges. Scars healed in a nearly imperceptible fashion, keeping within one cosmetic unit (the philtrum) without extending along the vermilion border as seen in bilateral advancement or rotation flaps. CONCLUSIONS: Island pedicle flaps may be an effective cosmetic and functional repair of selected surgical defects of the central upper lip involving the philtrum.     

Mohs '98: single-procedure Mohs surgery with immediate reconstruction

For more than 50 years, the Mohs technique has offered both the highest cure rate for skin cancers and the maximum preservation of surrounding normal tissue. Mohs skin cancer excision is traditionally performed by a Mohs dermatologist, followed by a secondary repair by a head and neck or plastic surgeon. This study comprises a review of 300 cases involving single-procedure Mohs therapy with immediate one-anesthetic reconstruction. The data reviewed include types of reconstructions, cosmetic results, complications, and recurrence rates. In addition to offering the psychologic and quality advantages of immediate closure, the procedure allows patients to return to work sooner. With changes in technique ranging from the chemosurgery of the 1930s to the fresh-tissue methods of the 1970s, single-procedure Mohs is the logical next step in the evolution of Mohs surgery.     

Experience with the practical use of a comprehensive estimation of the level of infectious and parasitic morbidity during the implementation of epidemiological surveillance by the State Epidemiological Health Surveillance Center in the Taganrog area

Although most ureteral stones can be treated with Extracorporeal Shock Wave Lithotripsy (ESWL) and endourology, there still is a small percent of patients whose stones can not be treated with minimally invasive techniques and thus require open surgery. Retroperitoneoscopic surgery is a good alternative for this subgroup of patients. It provides a direct access to the retroperitoneum, less morbid than an open operation and provides a better cosmetic result. On the very rare occasion open surgery with ureteral reimplantation to the bladder is required in those patients with lower ureteral stones. We have seen 1297 patients with stones larger than 5 mm in the ureter during the last 7 years. Among those undergoing watchful waiting 82% were stone-free; and that was 2.4% of all ureteral stones. Among those 1258 patients whom required a treatment 82.1% underwent in situ ESWL and 74.5% of them were rendered stone-free. In 8.9% of the patients ureteroscopy was performed (50% primary, and 50% for failed ESWL) with a stone-free rate of 75.8%. Open stone surgery was required in 8.9%, and retroperitoneoscopic surgery for ureteral stones was performed in only 0.15% of all patients. The best form of treatment for a ureteral stone is watchful waiting and the patient passing the stone without any intervention. Although that is the best scenario, this is a very painful condition and unfortunately most patients require some form of treatment. While ESWL for upper and mid ureteral non-obstructing and non-impacted stones is highly effective, stones in the lower ureter can be successfully treated via ureteroscopy. There still are some patients who require open surgery and retroperitoneoscopic surgery can be an alternative for this subgroup of patients offering a less morbid and better cosmetic result.     

Influence of fibrinolytic factors on scar formation after lumbar discectomy. A magnetic resonance imaging follow-up study with clinical correlation performed 7 years after surgery

STUDY DESIGN: Prospective cohort study. OBJECTIVES: To assess the amount of scar tissue by viewing magnetic resonance images, and to evaluate the correlation between the amount of scar tissue and clinical outcome, surgical technique, and fibrinolytic factors. SUMMARY OF BACKGROUND DATA: The influence of fibrinolytic factors on magnetic resonance images has not been investigated previously. The relation between clinical outcome and findings on magnetic resonance imaging remains uncertain. METHODS: Magnetic resonance imaging at 0.5 Tesla was performed to produce sagittal and axial spin-echo T1-weighted images before and after contrast enhancement on 78 patients 7 years after traditional lumbar discectomy with partial or full laminectomy. Before surgery all patients had been tested for fibrinolytic factors. RESULTS: The overall clinical success rate of the surgery was 73%. No evidence of scar formation was seen in 19 patients, a small amount was seen in 36 patients, a moderate amount in 17 patients, and a large amount was observed in 6 patients. Ten patients who had undergone surgery at two disc levels and 18 who had been treated with full laminectomy exhibited more scar tissue than those patients who had undergone surgery on a single level (P = 0.033) and those who had undergone a partial laminectomy, respectively (P = 0.017). The amount of scar formation also was associated with a poor outcome (P = 0.017) and with low preoperative values of tissue plasminogen activator antigen (P = 0.003) and tissue plasminogen activity (P = 0.048) in samples collected after venous occlusion. The intensity of contrast enhancement, however, was not influenced by these or any other parameters. CONCLUSION: The amount of scar formation after lumbar discectomy seems to be related to the clinical outcome, the size of the surgical exposure, and some fibrinolytic factors.     

The role of second-intention healing in periocular reconstruction

Second-intention healing is a time-honored method of wound management. Its role in periocular reconstruction, however, is currently controversial. The objectives of this thesis are threefold: to evaluate carefully the outcomes in a cohort of patients treated by this technique, to provide a comprehensive review of published reports, and to formulate recommendations and guidelines for appropriate application in selected patients. Eyelid and periorbital defects after excision of periocular tumors were allowed to heal by second intention in 59 patients. The locations of the wounds were the medial canthus (n = 32), lower eyelid (n = 20), upper eyelid, (n = 4), glabella (n = 2), and nasojugal fold (n = 1). Five excised areas involved the eyelid margin, and in three patients the defect included the canalicular system. The size of the defects ranged from 3 x 3 mm to 22 x 27 mm. The average duration of follow-up was 19 months (range, 6 months to 8 years). The functional and cosmetic results were satisfactory in 49 patients (83%). Complications occurred in 10 patients and included ectropion, medial canthal webbing, trichiasis, eyelid notching, and hypertrophic scarring. Only two patients, however, required secondary repair. Healing by second intention is a safe, effective, and inexpensive alternative to surgical reconstruction after tumor excision in selected patients.     

Value of reduction mammoplasty in the conservative treatment of breast neoplasms. Apropos of 70 cases

Breast cancer surgery is on the increase. Until now conservative treatment has been limited to tumors less than 3 cm; it is now extending to surgery on reduced tumors after chemotherapy or radiotherapy. Some cancers still require mastectomy because a carcinologic satisfactory tumorectomy would create a major deformity not compatible with conservative treatment. It is technically possible to perform major tumor resection with good cosmetic results using the reduction mammoplasty technique well known in plastic surgery. Between 1983 and 1991, 70 patients were treated at Henri Mondor Hospital for breast cancer with breast reduction mammoplasty and irradiation. We present the result with an average five years follow-up in terms of the cosmetic results relapses and survival rate. The actuarial local relapse was less than 10%, the survival with local relapse was 86% after 5 years, cosmetic results were good in 81% of cases. The association of reduction mammoplasty and radiotherapy seems to be a good extension of conservative treatment in some large breast tumors.     

Basal cell carcinoma of the genitalia

BACKGROUND: Basal cell carcinomas (BCC) arising on the genitalia are exceedingly rare with an unclear pathogenesis. OBJECTIVE: To better understand risk factors, tumor characteristics, and the possible role of human papillomavirus (HPV) in the development of BCC of the genitalia. METHODS: 1543 records of Mohs micrographic surgery performed during a 6-year period were reviewed to identify cases of BCC arising on the genitalia. Tumor tissue was analyzed for HPV DNA by in situ hybridization. RESULTS: Four patients with BCC of the genitalia were treated with Mohs micrographic surgery. The malignancies were located on the scrotum, perineum, and perianal areas in the three male patients and on the vulva in the female patient. The mean age was 67 years. None of the patients had prior history of skin cancers. Histologic evaluation of the tumors revealed two nodular subtypes, one superficial subtype, and one with follicular differentiation. In situ hybridization failed to reveal DNA of HPV types 6, 11, 16, 18, 30, 31, 33, 35, 45, 51, and 52. CONCLUSION: In this small series, genital BCC occurred in an older age group with no identifiable predisposing risk factors and did not show evidence of HPV infection.     

Reconstruction of the jaw and oral cavity with free vascularized grafts

59 microvascular graft transfers performed in 50 patients in our department since 1985 have been studied retrospectively. The indications for microvascular reconstruction were sequelae after tumour surgery in 38 patients, gunshot injury in seven, chronic osteomyelitis of the mandible in three, complication after jaw fracture in one patient, and atrophy of the alveolar ridge also in one patient. Transplants from the iliac crest, fibula, radius, radial forearm skin and jejunum were used. Three transplants were lost because of arterial thrombosis, giving a success rate of 94.9%. Complications were registered in 19 cases, the largest group being wound infections. 21 of the 50 patients have been treated with dental implants for total rehabilitation of masticatory function. Transfer of free vascularized bone and soft tissue grafts has greatly improved the functional and cosmetic results obtained in reconstructive surgery of the orofacial region.     

Comparative studies of the detection rates of Leishmania parasites from formalin, ethanol-fixed, frozen human skin specimens by polymerase chain reaction and Southern blotting

In this study, detection rates of Leishmania parasites from human skin were compared among three different types of specimens, formalin-fixed, ethanol-fixed, and frozen, by polymerase chain reaction (PCR) and Southern blotting. For this purpose, we used biopsy specimens collected from 19 leishmaniasis patients and performed PCR and Southern hybridization with the probe specific for Leishmania (Viannia) braziliensis complex. Among these 19, 16 specimens were from cutaneous leishmaniasis (CL), one, diffuse cutaneous leishmaniasis (DCL) and 2, mucocutaneous leishmaniasis (MCL) and were formalin-fixed and paraffin-embedded. The causative agents for one case of CL and one case of DCL were already identified as L. (Leishmania) complex. Six specimens of CL were preserved in 100% ethanol. Two specimens of MCL were frozen tissues. PCR using the formalin-fixed and paraffin-embedded specimens revealed positive bands at 70 bp in 9 (47.4%) out of 19 specimens of CL, MCL and DCL. Southern blotting detected the signals in 12 (63.2%) out of the 19. PCR using the 100% ethanol-fixed specimens revealed positive bands in 4 (66.7%) out of 6, and Southern blotting also detected the signals in 4 (66.7%) out of the 6. PCR and Southern blotting using 2 frozen specimens of MCL were always positive (100%). Although we failed to detect significant differences by Chi-square test between the results from the formalin-fixed, paraffin-embedded specimens and those from 100% ethanol-fixed ones, we concluded that ethanol-fixed specimens, convenient for transportation and storage, would be more useful for diagnosis of leishmaniasis by PCR in a developing country.     

Self-concept and self-esteem: a clarification of terms

Primary malignant non-Hodgkin lymphoma is rare. The mammographic appearance is unspecific. The final diagnosis can usually be made after examination of paraffin-embedded tissue only. There exists no therapeutic standard for this disease. In the case of 3 patients treated at our institution, tumorectomy only and adjuvant therapy have been performed because there is no survival advantage for patients who underwent radical surgery.
