Sarcomatoid renal carcinoma. A case report

Renal sarcomas are rare tumors. Prognosis is overall dismal. Adjuvant therapies should follow radical nephrectomy but no standardized regimen has been at present defined. We report a case of a patient affected by a sarcomatoid renal tumor to detect the best therapeutic approach to this rare tumor.     

Fine needle aspiration of secretory breast carcinoma resembling lactational changes. A case report

The purpose of the study was to determine if exhaled nitric oxide levels in children varied according to their asthmatic and atopic status. Exhaled nitric oxide was measured in a sample of 93 children attending the North West Lung Centre, Manchester, United Kingdom, for the clinical evaluation of a respiratory questionnaire being developed as a screening tool in general practice. The clinical assessment included full lung function, skin prick testing, and exercise challenge. Children were said to be asthmatic either by consensus decision of three independent consultant pediatricians, who reviewed all the clinical results except the nitric oxide measurements, or by positive exercise test. Atopic asthmatic children had higher geometric mean exhaled nitric oxide levels (consensus decision, 12.5 ppb [parts per billion] 95% CI, 8.3 to 18. 8; positive exercise test, 12.2 ppb 95% CI, 7.6 to 19.7) than did nonatopic asthmatic children (3.2 ppb 95% CI, 2.3 to 4.6; 3.2 ppb 95% CI, 2.0 to 5.0), atopic nonasthmatic children (3.8 ppb 95% CI, 2. 7 to 5.5; 5.7 ppb 95% CI, 4.1 to 8.0), or nonatopic nonasthmatic children (3.4 ppb 95% CI, 2.8 to 4.1; 3.5 ppb 95% CI, 3.0 to 4.1). Thus, exhaled nitric oxide was raised in atopic asthmatics but not in nonatopic asthmatics, and these nonatopic asthmatics had levels of exhaled nitric oxide similar to those of the nonasthmatics whether atopic or not.     

Fine needle aspiration cytology of lipid-secreting carcinoma of the breast. A case report

A renotropic factor was partially purified by sequential gel filtration and anion exchanger chromatography from plasma of human kidney transplantation donors and a renal cancer patient after uninephrectomy. This activity increased the rate of [3H]thymidine incorporation into DNA in rat cortical tubules, but not in rat liver cells, within the range of 100-200 ng/ml protein. The renotropic activity was detected between 7 and 12 days after uninephrectomy, and at least in 1 case decreased thereafter. This activity was undetected in gel-filtrated plasma of patients after a nonurological surgical procedure. The potency of this renotropic activity and its elution by gel filtration are similar to those displayed by a renal growth factor activity isolated from uninephrectomized rat plasma, as recently reported.     

Intracystic tumors of the breast

The authors report their experience obtained on the diagnostics of intracystic breast tumours in the last five years. It can be stated that ultrasound is currently the most valuable supplementary imaging method for the diagnosis of this rarely observed tumour. With the aid of ultrasonography, guided sampling can easily be carried out, and hence the preoperative diagnostic accuracy is increased. Pneumocystography is needed only in special cases.     

Bronchogenic carcinoma accompanied with gynecomastia. A case report

A case of bronchogenic carcinoma accompanied with gynecomastia was reported. The enlargement of bilateral breasts was discovered for 3 months before admission with continuous low grade fever, dyspnea and weight loss. The patient was a heavy smoker and had chronic bronchitis. Physical examination revealed bilateral enlargement of breasts, the diameter of each breast was 12 cm and the height was 6 cm. Serum human chorionic gonadotropin (HCG) was > 2000 miu/ml, prolactin (PRL) 41.5 ng/ml, luteinizing hormone (LH) > 200 miu/ml. The chest X-ray film showed scattered nodular shadows in both lung fields. Tumor cells were found in the lung tissue obtained by biopsy after death suggesting of adenocarcinoma. The pathogenesis of gynecomastia was discussed.     

Cytology of pigmented renal cell carcinoma. A case report

We used a new combined chemo- (COP/ABVD), radiation and interferon-alpha (10 x 10(6) IU s.c. 3x per week/12 months) therapy regimen to treat severe multicentric Castleman's disease (CD) complicated by relapsing Behcet's disease (BD) manifestations. More than 16 years after diagnosis of CD the patient remains in very good clinical condition, with remission of all CD and BD manifestations 13 months after discontinuation of the interferon-alpha treatment. In addition, our clinicopathological, immunohistological and virological data suggest a pathogenetic link between CD and BD via activation of pre-existing BD-specific plasma cells due to CD-related HHV8-induced overexpression of interleukin-6.     

Squamous cell carcinoma in ovarian endometriosis. A case report

A primitive squamous cell carcinoma of the ovary arose in ovarian endometriosis. The patient underwent a radical hysterectomy and radiotherapy. The other few similar reported cases had a poor prognosis. In our case the patient died 11 months after surgery.     

Ulcerated carcinoma of the breast in an elderly woman. An unusual clinical case report

The authors analyze the most current methods for the treatment of ulcerated breast cancer in the elderly. They describe a peculiar case recently observed, characterized by an ulcerative lesion spreading from the hemiclavicle to the foreaxilla including the axillary cavity, causing a large phlebo-lymphaedema, anaesthesia and paresis of the homoteral upper limb. After an initial treatment with tamoxifen a scapulo-humeral disarticulation and a suture of the cutaneous wide defect were performed using a myo-skin graft which included the deltoid muscle. A radiotherapeutic treatment followed by tamoxifen therapy was carried out. No distant metastases and no local relapses were registered in the one year follow up. The Authors on the basis of their experience and according to the review of the Literature suggest that age itself is not a limiting factor to the therapeutic approach of ulcerated breast cancer.     

Spindle cell carcinoma of right lower alveolus. A case report

A case report of spindle cell carcinoma of the right mandibular alveolus is reported, which clinically mimicked a squamous cell carcinoma. Careful histological interpretation is necessary for successful treatment of such tumors. The use of radiation therapy after radical neck dissection is also stressed upon.     

Bilateral orbital metastases from breast carcinoma. A case of false pseudotumor

OBJECTIVE: To inform clinicians of a metastatic orbital neoplasm that frequently masquerades as an orbital inflammatory syndrome and to stimulate thought regarding this neoplasm's fundamental pathobiology specific to its orbital involvement. DESIGN: Interventional case report and literature review. PARTICIPANTS: A 47-year-old woman with an acquired, bilateral, diffusely infiltrative orbital process is described. INTERVENTION: The clinical and radiographic features of the patient's orbital process are reported. The review of two prior fine-needle aspiration biopsy specimens failed to reveal a diagnosis. Histopathologic examination of an open surgical biopsy specimen included standard light microscopy of frozen and formaldehyde-fixed, paraffin-embedded tissue. RESULTS: Characteristics light microscopy findings suggested the diagnosis of metastatic lobular carcinoma of the breast. The patient refused all therapeutic intervention and died 9 months after orbitotomy. CONCLUSION: The presentation of breast carcinoma metastatic to the orbit as a bilateral infiltrative process is far more common than appreciated previously. Its rate of bilateral orbital involvement is 20%, whereas this rate for other adult neoplasms is much lower. The authors report an additional case, review the clinical features of previous case reports and series, and discuss aspects of the metastatic process. Breast carcinoma must be included in the differential diagnosis of infiltrative orbital processes encountered in adult female patients. When "orbital pseudotumor" is detected in an adult female patient, a thorough medical history must be obtained and physical examination performed. If a possible primary breast carcinoma is indicated, one must be wary of metastatic disease, and a histologic orbital diagnosis is warranted. The frequency of orbital metastasis and bilateral orbital involvement of this neoplasm reinforces the possibility for organ-specific metastases.     

Small cell carcinoma of the male breast: report of a case

An uncommon type of breast carconoma in a male studied by light and electron microscopy, is reported. Light microscopy reveals histologic characteristics and a pattern similar to infiltrating lobular carcinoma in the female breast. The ultrastructural study, because of close similarities in cellular characteristics with previously published reports, gives firm support to the light microscope findings.     

Clear cell renal carcinoma metastatic to the thyroid. A case report

A case of clear cell renal carcinoma metastatic to the thyroid 5 years after surgical removal of the primary tumor is presented. The differential diagnosis related to cyto-histologic findings, the uncommon occurrence and the unpredictable behaviour of clear cell renal carcinoma are discussed.     

Peridiscal metastatic carcinoma associated with lumbar disc herniation. A case report

Primary pulmonary tumors are infrequent in children. Bronchioloalveolar carcinoma has been documented rarely in the pediatric population. Before this report, there have been only three cases of bronchioloalveolar carcinoma in patients less than 16 years of age. Our two cases represent two of the youngest cases (ages 6 and 15 years) reported with bronchioloalveolar carcinoma. They illustrate many of the typical findings of this disease including clinical presentation, diagnostic difficulty, and better prognosis compared with other pulmonary malignancies. This neoplasm appears to have a favorable outcome in childhood.     

A rare case of epidermoid carcinoma of the breast

A case of a 76-year-old woman who seemed to suffer from Paget's disease of the breast, is reported. The patient was submitted to surgical of the breast, is reported. The patient was submitted to surgical treatment of the lesion and histological examination of the specimen showed a rare case of epidermoid carcinoma of the breast.     

Bullous pemphigoid as a paraneoplastic syndrome. A case report in renal-cell carcinoma

Paraneoplastic markers in tumor patients may occur at various stages of the disease. While some disorders almost invariably herald an underlying malignancy (obligative marker), most only occasionally do so (facultative marker). The association of bullous pemphigoid with malignancy is controversial. There are only a few reports of bullous pemphigoid associated with a renal cell carcinoma. We diagnosed a renal cell carcinoma in a 74 year old female patient, admitted to the hospital because of bullous pemphigoid. Multiple metastases were found in her lymph nodes, liver, lung and skeleton. The patient died eleven weeks after the first symptoms of bullous pemphigoid appeared.     

Atlantoaxial instability complicating radiation therapy for recurrent nasopharyngeal carcinoma. A case report

STUDY DESIGN: A case report of a patient in whom atlantoaxial instability developed secondary to repeat radiation therapy for recurrent nasopharyngeal carcinoma. OBJECTIVES: To illustrate a dramatic and previously unreported complication of local radiation to the posterior nasopharynx. SUMMARY OF BACKGROUND DATA: Nasopharyngeal carcinoma is an unusual tumor that usually is managed with local, external-beam radiation. It is not thought to involve the cervical spine directly, although local invasion of the skull base is common. METHODS: A review of the medical records and radiographs of the only patient known to develop this complication of radiation used to manage nasopharyngeal carcinoma. RESULTS: Atlantoaxial instability developed in a patient as a result of repeat radiation for a locally recurrent tumor. The instability was associated with intrusion of the anterior arch of C1 into the posterior nasopharynx and was managed successfully with a posterior stabilization using transarticular screws and supplemental wiring. CONCLUSIONS: Patients who have undergone local irradiation for nasopharyngeal carcinoma may be at risk for developing atlantoaxial instability.     

Hepatocellular carcinoma associated with precocious puberty and oral contraceptives. A case report

A 36-year-old woman presented with sudden abdominal pain and vomiting. Computed tomography showed a tumour of the right hepatic lobe with possible signs of acute haemorrhage. Her medical history revealed precocious puberty when she was a 5-year-old and the use of oral contraceptives for 18 years. Bisegmentectomy was performed and histological examination revealed hepatocellular carcinoma. The role of male and female sex hormones in the development of hepatic tumours has been well documented but, to our knowledge, association with precocious puberty has not yet been described.
