A case report: rare case of primary transitional cell carcinoma of the fallopian tube

Carcinomas other than adenocarcinomas are extremely rare in the fallopian tube. A 42-year-old woman with watery, intermittent vaginal discharge was found to have a left adnexal tumor. This case was diagnosed as primary carcinoma of the fallopian tube, FIGO Stage Ia. She underwent a total abdominal hysterectomy, a bilateral salpingo-oophorectomy, a pelvic and periaortic lymphoadenectomy, and an omentectomy, followed by cisplatin-based chemotherapy. Four years after the initial diagnosis of the disease, she remains in a disease-free state. Histologically, the tumor revealed a primary transitional cell carcinoma of the left fallopian tube. The findings on an immunohistochemical test for an epithelial membrane antigen, the CA125 antigen, were positive, whereas findings on a test for CEA were negative. We report a case of a malignant neoplasm of the fallopian tube with histological features of transitional cell carcinoma that arose from the tubal epithelium.     

Occult fallopian tube cancer in a patient with BRCA1 breast cancer

Primary fallopian tube cancer is very rare form of ovarian cancer. However, despite the infrequent incidence, emerging evidence suggests that patients who have a deleterious mutation of BRCA1 or -2 mutation may be more vulnerable to developing this disease. A patient with breast carcinoma was initially treated for her disease in 1994. She had a new primary lesion on the contralateral side in 2001 and was eventually identified with a positive BRCA1 germline mutation in 2007. The patient subsequently underwent a laparoscopic-assisted vaginal hysterectomy and bilateral salpingo-oophorectomy surgery performed by her gynecologist. Final pathology revealed occult stage IIC fallopian tube cancer with bilateral ovarian serosal involvement. Consequently, the patient was referred to gynecologic oncology and underwent a pelvic and paraaortic lymphadenectomy and laparoscopic omentectomy, followed by chemotherapy. Although fallopian tube cancer is rare, women who are positive for the BRCA mutation are at greater risk for developing this disease. Therefore, physicians should consider the associated risk factors and perform comprehensive risk-reducing surgery and staging when treating these patients.     

A case of primary transitional cell carcinoma of the fallopian tube.

The primary carcinoma of the fallopian tube is the rarest of all gynecologic malignancies and histologically most of them are adenocarcinomas. Primary transitional cell carcinomas are extremely rare in the fallopian tube. A 63-year-old postmenopausal woman presenting with lower abdominal pain was found to have a left adnexal mass. Exploratory laparotomy revealed a mass arising from the fallopian tube with the histologic features of transitional cell carcinoma. Light and electron microscopic studies supported the notion of transitional cell carcinoma. The tumor was extended to the muscle layer and confined to the left fallopian tube without metastasis. The patient received 3 courses of systemic cisplatin-based chemotherapy and has been well with no evidence of recurrence until August, 1998.     

Precursors to pelvic serous carcinoma and their clinical implications

Pelvic serous carcinoma has traditionally been viewed as a rapidly evolving malignancy, due principally to its late stage at diagnosis and tendency for poor outcome, both in the endometrium and the upper genital tract. Recently, studies of women with BRCA1 or BRCA2 mutations (BRCA+) undergoing risk reducing salpingo-oophorectomy have highlighted the distal fallopian tube as a common (80%) site of tumor origin and additional studies of unselected women with pelvic serous carcinoma have demonstrated that serous tubal intraepithelial carcinoma may precede a significant percentage of these tumors. This review examines the serous carcinogenic spectrum in the fallopian tube, highlighting recent evidence that these tumors may follow a defined precursor that has been present for a prolonged interval. The data supporting a candidate precursor, the implications of these findings for early detection and prevention of pelvic serous carcinoma and the caveats, are discussed.     

Management of bilateral fallopian tube carcinoma coexistent with tuberculous salpingitis

Primary carcinoma of the fallopian tube is a rare gynecologic malignancy. Chronic tubal inflammation is associated with primary carcinoma of the fallopian tube. There are only a few reports on primary carcinoma of the fallopian tube coexisting with tuberculous salpingitis. We are reporting a patient with both the primary carcinoma of the fallopian tube and tuberculous salpingitis, which were detected in bilateral fallopian tubes. The histologic type was serous adenocarcinoma. The patient was treated with total abdominal hysterectomy, bilateral salpingo-oophorectomy, infracolic omentectomy, and bilateral pelvic lymphadenectomy followed by chemotherapy consisting of paclitaxel and cisplatin. She has been alive without evidence of disease for 18 months.     

Laparoscopic management of fallopian tube carcinoma with paraneoplastic cerebellar degeneration

An asymptomatic tumor of the fallopian tube with elevation of serum CA125 concentration was found in a 75-year-old woman during a search for primary malignancy that was causing paraneoplastic cerebellar degeneration with a positive anti-Yo antibody. Since there were no apparent metastatic lesions detected by image diagnostic procedures, a diagnosis of early fallopian tube carcinoma was made preoperatively. After confirmation of the presence of a left tubal tumor without apparent invasion to the adjacent organs and peritoneal metastasis, laparoscopic salpingo-oophorectomy was subsequently performed. The histopathological diagnosis was of moderately differentiated serous adenocarcinoma of the fallopian tube with marked plasma cell infiltration. After surgery, the CA125 value immediately decreased, and there was no evidence of tumor recurrence noted thereafter. The patient died 51 months after surgery due to progression of neurological symptoms.     

Primary fallopian tube adenocarcinoma: preoperative diagnosis, treatment and follow-up

Preoperative diagnosis of fallopian tube carcinoma is difficult due to the rarity and silent course of this neoplasm. We present herein the case of a 58-year-old woman with primary fallopian tube carcinoma that was diagnosed preoperatively on the basis of a positive for adenocarcinoma Papanicolaou vaginal smear, repeated episodes of vaginal bleeding, negative endocervical and endometrial curettage, characteristic features on ultrasonography and elevated CA-125 levels. The patient was treated by total abdominal hysterectomy, bilateral salpigno-oophorectomy and omentectomy. Pathologic confirmation of primary serous papillary adenocarcinoma of the left fallopian tube was made. Peritoneal washings were positive for malignancy. FIGO stage was considered as IIIb and the patient received six courses of combined carboplatin-taxol chemotherapy. At two years from onset of therapy the patient underwent a modified radical mastectomy and lymphadenectomy because of primary carcinoma of the right breast. The patient was started on tamoxifen therapy, which she is still taking. At 60 months after initial surgery, the patient is alive and well. In conclusion, our study suggests an association between fallopian tube carcinoma and breast cancer and a good response of the patient to platinum-based chemotherapy.     

Pathologic findings in prophylactic oophorectomy specimens in high-risk women

OBJECTIVE: To ascertain the frequency of significant pathologic alterations in prophylactic oophorectomy specimens in high-risk women referred to a tertiary care center. METHODS: Surgical cases for prophylactic oophorectomy referred to a gynecologic oncology clinic from November 1996 to January 2001 were reviewed. Serial sections of entirely submitted tubes and ovaries were procured and reviewed by a pathologist with expertise in gynecologic malignancies. All patients had undergone genetic counseling and either underwent mutational analysis of BRCA1 and BRCA2 genes or had family history suggestive for ovarian and breast cancer susceptibility. RESULTS: Thirty women with either a documented deleterious BRCA1 or BRCA2 mutation or a suggestive family history underwent prophylactic oophorectomy during the study period. Seventy-three percent of women had undergone genetic testing. Of those, 63.5% harbored a BRCA1 mutation, 13.5% were BRCA2 carriers, and the remaining 23% tested negative. Five of the 30 women (17%) were found to have clinically occult malignancy. Four of the five were diagnosed only on histologic review. A single patient had grossly apparent primary peritoneal carcinoma at the time of laparoscopy. Three patients were found to have primary fallopian tube malignancy, two with in situ papillary serous carcinoma, and one with early invasive disease. Each of the fallopian tube neoplasms measured less than 1 cm. The final patient was diagnosed with an ovarian adenofibroma with a focus of low malignant potential neoplasm and clear cell features. Three of the five were known BRCA1 mutation carriers, one had a documented BRCA2 mutation, and one has not yet been tested. CONCLUSIONS: The high rate of occult malignancy detected in this series suggests that this finding in women at heightened risk for ovarian cancer is relatively common. Further, clinically occult tumors were not limited to ovarian origin, and the majority of cases harbored malignant foci less than 1 cm in greatest dimension that were not recognized at the time of surgery. These findings support the recommendations that in this high-risk population (1) the fallopian tubes and ovaries should be submitted entirely and be evaluated by a pathologist with expertise in gynecologic malignancies in serial sections; (2) laparoscopy and laparotomy are the surgical modalities of choice to allow inspection of the peritoneal surfaces at time of prophylactic oophorectomy and collect fluid for cytologic evaluation; (3) despite the rarity of fallopian tube carcinoma in the general population, BRCA1 and BRCA2 mutation carriers may be at increased risk for tubal cancers.     

Posthysterectomy carcinoma of the fallopian tube presenting as vaginal adenocarcinoma: A case report

The clinical and pathological features of a case of adenocarcinoma of the fallopian tube with a unique presentation are described. The 68-year-old patient presented with vaginal bleeding 25 years after a vaginal hysterectomy. Pelvic examination revealed a 0.5-cm nodule of tumor involving the mucosa of the vaginal apex. At laparoscopy, the left fallopian tube was dilated and adherent to the vaginal vault. Pathological examination of the upper vaginectomy and bilateral salpingo-oophorectomy specimen revealed a primary papillary adenocarcinoma of the left fallopian tube that had invaded directly into the mucosa of the vaginal apex. Vaginal involvement, either at the time of presentation or subsequently in the course of the disease, is very rare in patients with carcinoma of the fallopian tube.     

Atypical epithelial proliferation in fallopian tubes in prophylactic salpingo-oophorectomy specimens from BRCA1 and BRCA2 germline mutation carriers.

Although growing numbers of tubal carcinomas in carriers of BRCA1 and BRCA2 germline mutations have been reported, very little is known about the nature and frequency of their possible precursor lesions. The aim of this study is to investigate the occurrence of atypical proliferative tubal lesions in grossly normal fallopian tubes from 26 women with BRCA1 and BRCA2 germline mutations who underwent prophylactic salpingo-oophorectomy and whose ovaries were histologically negative for carcinoma. Fallopian tubes from 49 women who had undergone hysterectomy with salpingo-oophorectomy for uterine leiomyoma served as controls. In the 22 BRCA1-mutated women, there were two in situ carcinomas and two atypical hyperplasias of the tubal epithelium. The tubes of the BRCA2-mutated women and of the 49 control women did not show any atypical proliferation. The frequency of proliferative lesions of the tubal epithelium, including in situ carcinoma, appears to be increased in BRCA1 mutation carriers. Removal and thorough examination of the fallopian tubes at the time of surgical prophylaxis for ovarian cancer is therefore recommended.     

Transitional cell ovarian carcinoma in a BRCA1 mutation carrier

BACKGROUND:BRCA1 mutation carriers are at high risk of developing epithelial ovarian cancer, but the transitional cell variant has not been previously reported in these patients.CASE:A nulligravid, perimenopausal woman underwent exploratory laparotomy for a pelvic mass, ascites, and omental caking. Intraoperatively, frozen section of a tumor implant revealed high-grade epithelial ovarian carcinoma. Optimal surgical cytoreduction was performed. The final surgical pathology confirmed International Federation of Gynecology and Obstetrics stage IIIC transitional cell ovarian carcinoma. Her family history was significant for a sister with premenopausal breast cancer and a paternal aunt with ovarian cancer. The patient was counseled and elected to undergo genetic testing. Comprehensive gene sequence analysis detected the germline BRCA1 5382insC mutation.CONCLUSION:Transitional cell ovarian carcinoma is a rare histologic variant of epithelial ovarian cancer that may occur in BRCA1 mutation carriers.     

Management of advanced-stage primary carcinoma of the fallopian tube: case report and literature review

Primary carcinoma of the fallopian tube is a very unusual gynecologic malignancy that accounts for less than 1% of all malignancies of the female genitalia. A 55-year-old, gravida 7, para 3 woman presented with no gynecologic complaints other than backache. TVS demonstrated a 35 x 25 mm heterogeneous mass that was not clearly separated from the left ovary, and another 31 x 14 mm cystic septated lesion in the left ovary region. Pelvic MRI demonstrated a 35 x 35 x 20 mm left adnexal mass that enhanced with contrast and a neighboring tubular-cystic mass. Upper and lower gastrointestinal endoscopy revealed no malignancy. Serum CA 125-level was merkedly elevated at 369 U/ml (normal < 35 U/ml). Laparotomy revealed left hydrosalpinx and a papillary-fimbrial mass. Pelvic lymph node metastases were observed. Frozen-section analysis identified the mass as a serous adenocarcinoma. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, appendectomy, omentectomy, pelvic and para-aortic lymph node dissection, and peritoneal washing were performed. The definitive histopathological diagnosis was primary serous adenocarcinoma of the fallopian tube with six of 25 lymph node biopsies showing metastasis. Six cycles of paclitaxel (175 mg/m2) plus cisplatin (75 mg/m2) combinatin chemotherapy were administered with 3-week intervals between cycles. Second-look laparotomy was performed; there was no evidence of disease. At the time of writing 12 months after the second-look laparotomy, she was still disease-free.     

Clinical and pathologic findings of prophylactic salpingo-oophorectomies in 159 BRCA1 and BRCA2 carriers

OBJECTIVE: To estimate the likelihood of occult cancer diagnosis at prophylactic oophorectomy in BRCA1 and BRCA2 carriers in different age groups and to determine the histopathology of these lesions. METHODS: We describe a series of 159 female BRCA1 or BRCA2 carriers who underwent prophylactic oophorectomy at the University Health Network, Toronto from January 1, 1992 to June 30, 2004. RESULTS: Seven (4.4%) occult cancers were detected at pathologic examination. None of the 159 subjects had clinical signs or symptoms of ovarian carcinoma prior to, or at the time of, surgery. Only two cancers were grossly visible at surgery. There were 94 BRCA1 carriers, of whom six were found to have an occult cancer (6.4%). In contrast, only one of the 65 BRCA2 carriers was found to have an occult cancer (1.5%). Three of the seven cases of occult malignancy involved the fallopian tube and not the ovaries. CONCLUSION: Approximately 6% of BRCA1 carriers and 2% of BRCA2 carriers who undergo prophylactic salpingo-oophorectomy will be found to have occult carcinomas if the ovaries and tubes are rigorously examined. A significant proportion of these appear to originate in the fallopian tube. No cancers were detected among women who had the operation at age 39 or younger.     

Primary fallopian tube carcinoma in a 51-year-old postmenopausal woman--case report

The case of a 51-year-old woman with a primary carcinoma of the left fallopian tube is presented. Laparotomy performed for an ovarian tumour revealed that the patient had normal ovaries, but a left fallopian tube was dilated and filled with a tumour mass. Histopathological examination revealed primary adenosquamous cell carcinoma of the fallopian tube.     

Primary fallopian tube carcinoma with isolated torsion of involved tube

BACKGROUND: Primary fallopian tube carcinoma (FTC) is an aggressive but rare tumor. Worldwide, more than 1,500 cases have been published, and about 20 new cases are added every year. Isolated fallopian tube torsion (IFTT) is an unusual and uncommon event. CASE: We report a 69-year-old Caucasian woman, Gravida 4, Para 3, with a long history of hypertension, diabetes mellitus with retinopathy and neuropathy, and history of extensive coronary artery disease, for which a triple-by-pass graft was performed. She was placed on anticoagulation therapy. Subsequently, she developed intermittent vaginal bleeding. RESULTS: We reviewed and discussed the symptoms and work-up of the patient in detail. She underwent exploratory laparotomy, and primary FTC with isolated torsion of the involved fallopian tube was diagnosed. Peritoneal washings, omentectomy, total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. CONCLUSION: Review of the English literature on the presenting symptoms and diagnostic management of primary FTC and IFTT is presented.     

Germline BRCA2 mutation in a patient with fallopian tube carcinoma: a case report

OBJECTIVES: Fallopian tube carcinoma is similar to ovarian and peritoneal carcinoma with respect to histology, response to chemotherapy, and prognosis. BRCA germline mutations have been commonly reported in ovarian and peritoneal carcinoma but rarely in other gynecologic cancers. METHODS: A patient with fallopian tube carcinoma and a family history of ovarian carcinoma underwent genetic counseling and BRCA testing as did her daughter. RESULTS: The patient and her daughter were found to have a germline BRCA2 mutation. CONCLUSION: Like a family history of ovarian or peritoneal carcinoma, the occurrence of fallopian tube cancer should alert the clinician to the possibility of an abnormality in the breast cancer susceptibility 1 or 2 genes.     

Prophylactic salpingo-oophorectomy in 51 women with familial breast–ovarian cancer: importance of fallopian tube dysplasia

We report our findings on 51 patients with a familial breast and/or ovarian cancer risk who underwent prophylactic bilateral salpingo-oophorectomy (pBSO). Patients undergoing a pBSO between January 1, 1997, and December 31, 2003, at the University Hospitals Leuven were reviewed retrospectively. Out of 51 patients, 37 (72.5%) underwent genetic testing, while the 14 others (27.5%) underwent pBSO on the sole basis of a positive family history only. BRCA1 mutation was found in 35% of the tested group, while 30% were BRCA2 carriers. Mean age at intervention was 45.3 years; 33 patients were premenopausal. In 44 patients (86%), the pBSO was performed laparoscopically, and in seven patients we decided laparotomy because of technical reasons. In four patients hysterectomy was performed. Histopathologically, the presence of epithelial dysplasia was observed in two patients (dysplasia of the fallopian tube in a BRCA2 patient; discrete focal atypia of tubal and ovarian epithelium in a patient with a negative BRCA1/BRCA2 mutation analysis). Peritoneal cytology specimens (n= 28) were all negative. Laparoscopic pBSO is well tolerated. Concomitant hysterectomy should be considered, given the observed fallopian tube dysplasia and the possibility of a tubal remnant after pBSO.     

Primary carcinoma of the fallopian tube mimicking tubo-ovarian abscess

PURPOSE: The aim of the study is to report that the primary fallopian tube cancer can be presented as a tubo-ovarian abscess preoperatively. METHODS: A patient with a preoperative diagnosis of a tubo-ovarian abscess with abdominal pain, tenderness and an elevated fever with leukocytes underwent urgent exploratory laparotomy. RESULTS: Explorative laparotomy and accompanied frozen section revealed a right-sided tubal carcinoma. There was an inflammatory and purulent reaction in the tube that was adherent to the anterior uterus. Total hysterectomy and bilateral salpingo-oophorectomy were performed. CONCLUSION: Carcinoma of the fallopian tube should be considered in the differential diagnosis of acute pelvic peritonitis like a tubo-ovarian abscess.     

Primary Transitional Cell Carcinoma of the Fallopian Tube: A Case Report and Review of the Literature

Primary carcinoma of the fallopian tube is extremely rare and the preoperative diagnosis is often misdiagnosed as an ovarian carcinoma. We report a patient with primary carcinoma of the fallopian tube, strongly suspected preoperatively on the basis of characteristic clinical symptoms, elevated CA125 levels, and transvaginal sonography, computed tomography, and magnetic resonance imaging findings. The histology of fallopian tube carcinoma was demonstrated as transitional cell carcinoma. Extensive review of the literature showed that our case seemed to be the 14th case of primary transitional cell carcinoma of the fallopian tube.
