Primary Fallopian Tube Carcinoma: A Case Report and Literature Review

Primary fallopian tube carcinoma diagnosed 29 years after bilateral partial salpingectomy: A case report

Salpingectomy has a reported theoretical decreased risk of tubal and ovarian cancers. Here we describe a case 29 years after partial salpingectomy.

Mature Cystic Teratoma at Fallopian Tubes: A Case Series

Benign tumors of the fallopian tube are uncommon. Teratomas are most frequently found in the ovary and fallopian tube teratoma is extremely rare. To date, around 70 cases have been described, and most of them were discovered by chance. Here we present two cases of fallopian tube dermoid cyst. The first case is of a woman who was unable to conceive for 4 years with a right ovarian dermoid. She was managed with laparoscopic cystectomy when she was found to have a small teratoma-like lesion at the fimbrial end of the left fallopian tube. The second case is of a female who underwent elective caesarian section and was found to have a teratoma-like lesion at the right fallopian tube. Histopathology of both cases were reported as mature cystic teratoma. These cases suggest the need for careful examination of the pelvic organs for other pathology apart from the primary surgical sites.

Leydig Cell Hyperplasia of Ovary - An Unusual Finding in Postneoadjuvant Chemotherapy Case of Primary Fallopian Tube Carcinoma

A large number of high-grade serous ovarian carcinomas originate in the fallopian tubes. Neoadjuvant chemotherapy followed by surgery may lead to a number of chemotherapy-induced changes in the ovary, which may lead to an erroneous diagnosis. We present a rare case of a 55-year-old postmenopausal woman who was clinically diagnosed with carcinoma of the right ovary; on histopathologic evaluation after neoadjuvant chemotherapy, the primary site was found to be the right fallopian tube. The right ovary showed chemotherapy-related changes along with extensive Leydig cell hyperplasia. As the presence of Leydig cell hyperplasia in this setting is an unusual finding, it may pose a diagnostic dilemma for the pathologist; so an awareness of this entity is important to avoid misdiagnosis.

Synchronous Primary Endometrial and Fallopian Tube Carcinoma with Metchronous Renal Pelvis Carcinoma in One Patient: "Triple Cancer- A Rare Occurrence"

Triple primary cancers in one patient are a very rare finding and occur in only 0.5% of patients with cancers. Here, we report the case of triple malignancy in a 62-year-old woman who developed synchronous primary endometrial endometroid type and serous type of fallopian tube carcinoma, which is again a rare finding after 4 years of diagnosis of transitional cell carcinoma of the right renal pelvis.

Primary Fallopian Tube Cancer in an 89-Year-Old Patient

Fallopian tube cancer is an extremely rare gynecological condition, accounting for just 1 to 2% of all female tract malignancies. The mean age of diagnosis is similar to that of ovarian cancer, between 60 and 75 years, but it can affect a wide spectrum of ages. Advanced age and family history of ovarian and breast cancer are the main risk factors, since they are associated with increased incidence of this uncommon entity. In this study, we report a rare case of an elderly, 89-year-old patient that presented to our clinic due to vaginal bleeding.

Fallopian tube cancer- challenging to diagnose but not as infrequent as originally thought

Background: Primary fallopian tube carcinoma (PFTC) is a rare gynecological malignancy though its prevalence may be underestimated given that most ‘ovarian’ serous cancers originate in the fallopian tube. Its diagnosis is challenging due to its vague signs and symptoms on presentation and it is frequently under-diagnosed pre-operatively.

Case Presentation: We present a case of a pre-menopausal woman who presented with vaginal bleeding. Her laboratory testing and physical examination were grossly unremarkable. Gynecologic ultrasound demonstrated multiple uterine fibroids and a double layer endometrium measuring 4.5 mm. More importantly, the left ovary was seen with a complex cyst with mildly echogenic fluid and a solid excerscence. These findings were suspicious for malignancy. The clinical and radiological findings with elevated CA-125 were consistent with a malignant process. Patient subsequently underwent a diagnostic laparoscopy, which required conversion to exploratory laparotomy, supracervical hysterectomy, bilateral salpingo-oophorectomy, right ureteral lysis, right para-aortic and right pelvic lymph node debulking and omentectomy. Biopsy of left fallopian tube and ovary revealed invasive high-grade serous carcinoma of fallopian tube, with involvement of lymphovascular spaces and with surface involvement. Peritoneal washings were negative for malignancy.

She was diagnosed with a high-grade serous carcinoma of the fallopian tube after undergoing an endometrial biopsy, multiple imaging tests and finally surgical intervention that yielded the diagnosis. She was started on chemotherapy with carboplatin and paclitaxel.

Conclusion: Our aim is to highlight the importance of having PFTC among the differential diagnosis when women present with vaginal bleeding or abdominal pain, as the clinical presentation of PFTC tends to be non-specific, and is often under-diagnosed; reviewing the diagnosis and management, and characterizing the similarities and differences of PFTC with other gynecological malignancies such as ovarian cancer.

Primary High Grade Serous Carcinoma of the Fallopian Tube: A Case Report

A 49-year-old, perimenopausal nulliparous woman with lower abdominal pain and abnormal uterine bleeding. Clinical and radiological findings suggested a right adnexal tumor. CA-125 level was moderately elevated. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was done. Peroperative findings revealed a soft to friable growth arising from right fallopian tube with no involvement of ovaries. Histopathologic examination confirmed it to be a high grade serous carcinoma, FIGO stage IA. The histomorphology resembled high grade serous carcinoma of ovary, however ovaries on both sides appeared unremarkable. Surgery was uneventful and the patient was discharged after seven days of hospital stay. She did not receive postoperative chemotherapy or radiotherapy and is under follow-up. The case is reported for its occurrence in an uncommon anatomic site and preoperative dilemma with relevant review of literature.

Fallopian Tube Tumor Mimicking Primary Gastrointestinal Malignancy

A 67-year-old female patient positive for a mismatch repair gene mutation and history of serous carcinoma of the fallopian tube presented with a lower gastrointestinal bleed. Clinical workup was suggestive of a primary gastrointestinal malignancy. Pathological review after right hemicolectomy revealed the primary tumor was a fallopian tube carcinoma. Over the next few years, she presented with upper and lower gastrointestinal bleeds from a recurrent metastatic disease, which was from the primary fallopian tube cancer. Although serous carcinoma of the fallopian tube is not an uncommon diagnosis, it is unusual for it to present with symptoms of recurrent gastrointestinal bleed mimicking a primary gastrointestinal malignancy.

Port-site metastasis as a primary complication following diagnostic laparoscopy of fallopian tube carcinoma: A case report

RATIONALE

Fallopian tube carcinoma is a rare female genital cancer with no specific clinical and surgical features. It is hardly diagnosed on imaging due to non-specific presentation. Laparoscopy has been recommended as the diagnostic procedure for the assessment of suspicious ovarian and adnexal masses. However, it has brought new complications like tumor recurrences at the trocar insertion sites, called port-site metastasis (PSM).

PATIENT CONCERNS

A 65-year-old, postmenopausal woman presented to hospital with loss of appetite, Ultrasound showed ill-defined pelvic mass. The patient was diagnosed with fallopian tube carcinoma by a diagnostic laparoscopy.

DIAGNOSES

The PSM as a primary complication following diagnostic laparoscopy of fallopian tube carcinoma, which is presumed by positron emission tomography/computed tomography and confirmed by Nodule resection and further pathological assessment.

INTERVENTIONS

As port-site metastasis was suspected, the patient was advised to undergo umbilical mass resection.

OUTCOMES

the patient has no signs of recurrence was detected 20 months after the last surgery during follow-up.

LESSIONS

Laparoscopy plays a significant role in the diagnose and treatment of fallopian tubal and ovarian malignancies but has a risk of PSM occurrence. When isolated PSM occurs the management should be local resection.
