Ultrasonographic appearance of fallopian tube carcinoma

Preoperative diagnosis of tubal carcinoma is difficult and a diagnosis cannot usually be established until the time of operation. However, since prognosis is strictly related to the stage of the neoplasm, it is very important to be familiar with the clinical and imaging characteristics of primary fallopian tube carcinoma in order to make an early and accurate diagnosis. This report presents the ultrasonographic features of three cases of fallopian tube carcinoma and reviews the literature on the subject.     

Children with chronic arthritis: the management of transition to adulthood

Primary fallopian tube carcinoma represents less than 1% of all gynecologic malignancies and is therefore one of the less common malignancies of the female genital tract. Fallopian tube carcinoma is rarely diagnosed preoperatively and is often mistaken for benign pelvic disease or ovarian cancer. Compared with ovarian carcinoma, fallopian tube cancer more often presents in early stage but seems to have a worse prognosis, stage for stage. Treatment consists of surgical debulking followed by chemotherapy, adjuvant or otherwise. New studies are needed to better delineate the clinical course, prognostic factors, and appropriate chemotherapy recommendations.     

Tracheal intubation in infants

BACKGROUND: So far only a few cases of carcinoma in situ of the fallopian tube have been reported, but its detailed clinical and pathologic findings, including cytology, have not been fully described. CASE: A 70-year-old female was admitted to our hospital because of irregular genital bleeding. Endometrial smear revealed a small number of atypical cells with a clear background. Hysterectomy, bilateral salpingo-oophorectomy and omentectomy were performed. Grossly, a grayish white papillary tumor, measuring 1.5 x 1.0 cm, was observed within the lumen of the left fallopian tube. Microscopically, the diagnosis of papillary adenocarcinoma in situ of the left fallopian tube was made according to 1992 International Federation of Gynecologists and Obstetricians fallopian tube staging. CONCLUSION: Although endometrial brush cytology is not sensitive enough to detect a primary carcinoma of the fallopian tube, our case indicates that it may contribute useful information on extrauterine diseases and can detect a stage 0 cancer of the fallopian tube. Clinicians, as well as pathologists, should consider the possibility of fallopian tube cancer if cervical or endometrial cytology shows atypical cells with papillary patterns with a clear background but endometrial curettage cannot prove malignancy.     

Haemorrhagic hydrops of the gallbladder

Primary carcinoma of the fallopian tube is uncommon; optimal primary treatment is still not well defined, and little information is available about the efficacy of cisplatin-based combination chemotherapy. Thirty-eight patients with fallopian tube carcinoma were treated with cyclophosphamide (500 mg/m2), Adriamycin (50 mg/m2), and cisplatin (50 mg/m2) (CAP). Thirty-two patients received the combination chemotherapy as first-line treatment after cytoreductive surgery, whereas six subjects were treated for recurrent disease. The patients received a median of six cycles of therapy (range, four to nine). At the initiation of chemotherapy, 24 patients had measurable lesions. In this group of patients, 15 had a clinical complete response (CR), four had a partial response (PR), three had stable disease (SD), and two had progressive disease (PD) after chemotherapy. The overall clinical response rate (CR + PR) was 80%. Ten of the 14 CR patients who were submitted to second-look operation (SLO) were found free of disease, in pathologic complete response (pCR). Three pCR patients relapsed, and two of them died despite second-line treatment. Nine patients achieving PR, SD, and PD after first-line chemotherapy were further treated (five with chemotherapy, two with radiotherapy, two with progesteron), but none responded to second-line treatment and all died (median survival, 9 months). Fourteen patients without gross residual disease after cytoreductive surgery had no measurable lesions and were not evaluable for response. Seven of them had negative SLO and remain disease free. Three patients (two stage III and one stage II) who refused SLO relapsed 14, 16, and 26 months after completion of chemotherapy. The median survival for the entire group was 38 months, and the 5-year survival rate was 35%. The toxicity of the regimen was moderate. The CAP regimen appears to be active in primary fallopian tube carcinoma and yields response rates comparable to those reported for epithelial ovarian cancer.     

Leiomyomas of the fallopian tube. A case report

Both heterotopic pregnancies and primary neoplasms of the fallopian tube are rare occurrences. A patient presented with early pregnancy, abdominal pain and ultrasound findings of an intrauterine gestation and a fallopian tube mass. Laparotomy revealed a primary leiomyoma of the fallopian tube.     

Genomic alterations in fallopian tube carcinoma: comparison to serous uterine and ovarian carcinomas reveals similarity suggesting likeness in molecular pathogenesis

Serous carcinomas of the fallopian tube, uterus, and ovary resemble each other both histologically and in clinical behavior. Comparative genomic hybridization was performed on 20 primary fallopian tube carcinoma specimens to find regions of the genome involved in tubal carcinogenesis and to compare the genomic alterations with those previously detected in serous ovarian and uterine carcinomas. The most frequent changes detected in fallopian tube carcinoma were gains at 3q (70%) and 8q (75%), with high-level amplifications in several cases. Other common gains occurred at 1q, 5p, 7q, 12p, and 20q. The most frequent losses were found at 18q, 8p, 4q, and 5q. The frequency and the pattern of chromosomal changes detected in tubal carcinoma were strikingly similar to those observed in serous ovarian and uterine carcinomas, suggesting common molecular pathogenesis.     

Argon laser therapy of benign tumors of the eyelid

Although a common site of metastases, primary fallopian tube carcinoma comprises only 0.3% of all gynaecological malignancies. Presenting symptoms are variable and non-specific, with preoperative diagnosis rarely entertained. The FIGO system assigns nearly two-thirds of patients to stage I or II and is based on surgical staging criteria similar to those for ovarian cancer. Likewise, management is based on that for ovarian cancer-radical debulking followed by platinum-based combination chemotherapy. Five-year survival for patients with disease confined to the tube at diagnosis (stage I) is only about 60% and only 10% of patients with advanced disease will be cured.     

Use of overlapping synthetic peptides to characterize samples from blood donors with indeterminate results to hepatitis C virus core antigen

The diagnosis of occult fractures of the scaphoid bone is even more challenging than that of conventional fractures of the scaphoid. This study aimed to compare prospectively the gold standard method (plain radiographs in four projections, after about 14 days) and the primary findings with direct magnification radiography (DIMA) and magnetic resonance imaging (MRI). Primary MRI showed much higher diagnostic power than plain radiography at 10-14 days in occult scaphoid fractures and in detection of associated carpal injuries. This may lead to a decreasing time of disease. DIMA was inferior in detecting occult fractures of the scaphoid.     

Dermatomyositis associated with fallopian tube carcinoma

Dermatomyositis (DM) is an idiopathic inflammatory myopathy associated with characteristic cutaneous and extracutaneous manifestations, including malignancy. Primary fallopian tube carcinoma (FTC) is the least common site of origin for a malignant neoplasm of the female genital tract. This report describes the first documented case of DM and concurrent FTC in the United States. A 62-year-old woman presented with DM and was subsequently found to have FTC. During her clinical course, she had improvement in strength and function with treatment of the underlying FTC, which also correlated with lower creatinine phosphokinase levels. An association between DM and FTC may exist because of significant functional strength improvements after tumor removal and chemotherapy.     

Merkel cell carcinoma of the skin

Primary neuroendocrine carcinoma of the skin or Merkel cell carcinoma is an aggressive primary neoplasm. It is commonly seen in the elderly, on the head, neck and extremities, where it can mimic a benign or less malignant skin tumour. Pathological examination shows a generally dense growth of small dark cells, with immunohistochemical evidence of neuroendocrine differentiation. The microscopic appearance is very similar to metastatic oat cell carcinoma from the lung and this must be excluded by clinical means and appropriate imaging studies. In this study we present 13 new cases of Merkel cell carcinoma (the largest published series in the UK) and summarize 214 cases from the literature in which the survival data are given. In our series, 5 of 13 patients died from spread of the Merkel cell carcinoma. From this and other studies, it appears that early diagnosis and wide local excision may be the only way to prolong survival. No other adjuvant therapy has proved effective.     

Calcium channel blocker decreases pentagastrin-stimulated alkaline-tide: a role for extracellular calcium in gastric acid secretion

The value of magnetic resonance imaging (MRI) in the diagnosis and staging of endometrial carcinoma was studied in 43 cases of clinically suspected endometrial carcinoma and 7 normal women. All of the 43 cases showed abnormal endometria measured by MRI, among which were pathologically proven 40 cases of endometrial carcinoma, 2 cases of endometrial polyps and 1 case of adenomyosis. This suggested that MRI showed a high susceptibility in the diagnosis of endometrial carcinoma, and a lack of specificity. MRI could predict myometrial invasion, its accuracy being verified by surgico-pathological findings in 11 of 13 cases. MRI staging was correct in 10 of the 13 primarily operated cases, and only half of the clinical staging was in conformity with surgical staging. The results suggest that MRI is useful in the staging of endometrial carcinoma and therefore is of value in the choice of treatment planning, although it is not yet an ideal diagnostic aid to detect small metastatic pelvic lesions.     

Isolated torsion of the fallopian tube. A case report

BACKGROUND: While torsion of the adnexa is relatively common, isolated torsion of the fallopian tube alone remains a rare occurrence. Diagnosis and surgical intervention are often delayed. CASE: A 38-year-old woman presented with acute lower right abdominal pain initially managed as renal colic. She returned to the emergency department three days later. After surgical consultation, a computed tomography scan and ultrasound showed a cystic pelvic mass with normal ovarian flow studies. Ultimately, the gynecology team performed laparoscopy with the suspicion of intermittent adnexal torsion. A 6 x 8-cm, twisted, dusky purple right fallopian tube was noted. A laparoscopic salpingectomy was performed. CONCLUSION: In the differential diagnosis of acute lower abdominal pain, isolated torsion of the fallopian tube should be considered. A timely diagnosis and surgical intervention may allow preservation of the tube. Even when irreversible damage has occurred, laparoscopic management is recommended.     

Selective salpingography and tubal cannulation through hysteroscopy

In this paper the procedure of selective salpingography and tubal cannulation through hysteroscopy for diagnosis and treatment of fallopian tube obstruction at the interstitial portion was introduced. We combined hysteroscopic tubal cannulation with selective salpingography under fluoroscopic quidance in 28 infertile women with 49 obstructed interstitial portion of fallopian tubes diagnosed previously. After the procedures 27 tubes (55.1%) became patent in 16 cases. In 16 women with patent tubes followed up over 6 months after the procedures 5 intrauterine pregnancies occurred. This procedure is a safe and simple diagnostic method to identify fallopian tube obstruction at the interstitial portion and may alos serve as a therapeutic approach in some of these patients.     

Clarithromycin, amoxycillin and H2-receptor antagonist therapy for Helicobacter pylori peptic ulcer disease in Korea

OBJECTIVE: To compare the efficacy of fallopian tube sperm perfusion utilizing a Foley catheter technique with standard IUI. DESIGN: Randomized controlled study. SETTING: The infertility units of the University Central Hospital and the Family Federation of Finland, Oulu, Finland. PATIENT(S): One hundred infertile women with unexplained factor, minimal to mild endometriosis, mild male factor, or ovarian dysfunction, undergoing 50 IUI and 50 fallopian tube sperm perfusion cycles stimulated by clomiphene citrate and hMG. INTERVENTION(S): Thirty-six hours after hCG administration, patients were randomized to either the IUI group (group 1, 50 patients and cycles) or the fallopian tube sperm perfusion group (group 2, 50 patients and cycles). Intrauterine insemination was performed using a standard method and fallopian tube sperm perfusion with a pediatric Foley catheter, which prevents the reflux of sperm suspension. MAIN OUTCOME MEASURE(S): Number of clinical pregnancies. RESULTS(S): The fallopian tube sperm perfusion method using a Foley catheter technique was easy to perform and convenient for the patients. The overall pregnancy rate per cycle was 8% for fallopian tube sperm perfusion and 20% for IUI, a difference that was not significant. CONCLUSION(S): The fallopian tube sperm perfusion method using a Foley catheter offers no advantage in comparison with the conventional IUI technique.     

MR lesion detection in a breast cancer population

Implementation of MR imaging of the breast as an extension of the existing imaging modalities in the diagnosis of breast cancer was evaluated in a university cancer center, MR imaging of the breast was performed in 54 patients, in whom the MR results were compared with the triple test (the combination of clinical examination, mammographic evaluation, and cytology) and the final histological diagnosis. MR imaging of the breast depicted 30 of the 33 malignancies (sensitivity, 91%). In two of the malignancies, the carcinoma was clinically and mammographically occult. For the three patients with a false-negative MRI diagnosis, the conventional mammography showed suspicions clustered microcalcifications as a sign of in situ carcinoma. For seven patients, MR imaging of the breast incorrectly suggested the presence of a malignant lesion (specificity, 67%). To improve MR specificity, we perform MR-guided ultrasonographic fine-needle aspiration biopsy (FNAB). Although MR imaging of the breast is a highly sensitive examination, conventional x-ray mammography remains the most efficient imaging modality in the diagnosis of breast cancer. In our patient population, MR imaging of the breast had additional value for women with mammographically dense breast tissue and especially for patients with clinical evidence of breast carcinoma that could not be detected with conventional diagnostic methods.     

Mitochondrial DNA in idiopathic cardiomyopathy

143 women treated in 28 departments from 1980 to 1995 were retrospectively analysed to study the impact of prognostic factors in primary carcinoma of the fallopian tube. The mean age of the patients was 62.5 years. Sixty (42%) tumours were FIGO stage I, 28 (20%) stage II, 38 (27%) stage III, 17 (12%) stage IV. Complete radical resection was achieved in 102 (71%) patients. In 122 (85%) women, surgery involved removal of the uterus, the adnexa, and/or the omentum or lymph nodes. Postoperative therapy consisted of either irradiation (n = 40; 28%) or chemotherapy (n = 70; 49%); 33 women (23%) did not receive any treatment after surgery. The 5-year survival rate for all cases was 43%. The 5-year survival rate was 59% for stages I and II and 19% for stages III and IV (P < 0.00001). FIGO stage, histological grade and presence of residual tumour had an independent prognostic impact in multivariate analysis. In order to investigate the role of p53 in primary fallopian tube carcinomas, we analysed the immunohistochemical expression of p53 protein regarding survival and FIGO stage in 63 patients (44%). No statistical significance was observed.     

MRI and CT of metastatic hepatocellular carcinoma causing spinal cord compression

We report the imaging features in five patients with metastatic hepatocellular carcinoma causing spinal cord compression, three of which were biopsy proven and two were in patients with known diagnosis of hepatocellular carcinoma. The radiographic, magnetic resonance imaging (MRI) and computed tomography (CT) features are highlighted. Although the occurrence of metastatic disease in hepatocellular carcinoma is exceedingly rare, it may be increasingly encountered as survival of patients is improved with advancing methods of therapy, both surgical and palliative. It often accompanies local recurrence, and invariably signals a grave prognosis with extremely short life expectancy. Unusually, two of the five patients in this series presented initially with skeletal metastases which led to the diagnosis of hepatocellular carcinoma.     

A case of large neonatal arteriovenous malformation with heart failure. Color Doppler sonography, MRI and MR angiography as early non-invasive diagnostic procedures

We report a case of a large arteriovenous malformation (AVM) of neonatal onset with heart failure. Transfontanel color Doppler sonography revealed abnormal vessels in the early stage of the investigation. Magnetic resonance imaging (MRI) revealed numerous flow voids suggesting abnormal vessels, and magnetic resonance angiography (MRA) disclosed numerous bizarre abnormal vessels. Color Doppler sonography is a convenient and appropriate procedure for the early bedside diagnosis of neonatal AVMs. MRI and MRA can replace cerebral angiography for the diagnosis of neonatal AVMs.     

Characteristics of ANP-binding sites in the adrenal capsules of term-pregnant rats

Magnetic resonance imaging (MRI) of the cervical spine was performed on 20 patients (mean age 10 years) with a preliminary diagnosis of juvenile rheumatoid arthritis (JRA). In all patients conventional x-rays of the cervical spine were obtained, and the relationship between clinical status and MRI findings were evaluated. Two patients with clinical manifestations, including neck pain and diminished range of motion, exhibited significant pathologic features on radiogram and MRI, the latter providing more detailed information. Among 18 patients who had no complaints about their cervical spines, 3 patients (65%) had either soft tissue involvement, pannus formation or erosions on the surface of atlantoaxial joints; only four patients (20%) had erosions on plain x-ray views. Since the early diagnostic ability of MRI in JRA allows early therapeutic intervention, every patient with a probable diagnosis of JRA would benefit from MRI.
