Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Primary fallopian tube carcinoma is uncommon, but when it occurs the dominant histological type is adenocarcinoma of serous type, accounting for roughly half to over eighty percent of cases.
Step 2: The tube is lined by Mullerian-type epithelium, so the tumours that arise resemble the serous carcinomas of the ovary. Current understanding even regards the tubal fimbria as the origin site for many high-grade serous carcinomas attributed to the ovary.
Step 3: The distractors are not typical tubal cancers. Squamous cell carcinoma is a cervical or vaginal type, teratoma is a germ cell tumour of the gonad, and choriocarcinoma is a trophoblastic tumour. None is the usual fallopian tube malignancy.
Step 4: Hence the most common malignancy of the fallopian tube is serous carcinoma.
