Post hysterectomy mesonephric carcinoma

Abstract

Mesonephric carcinoma is a rare type of carcinoma seen in the female genital tract. It arises from the mesonephric remnants situated in the broad ligament, lateral wall of the cervix, vagina, and uterine corpus. Very few cases of mesonephric carcinoma have been reported so far in the literature. The sites mentioned in various literatures include the cervix, vagina, or uterus, but we could not find any literature that mentions posthysterectomy vault as a site for mesonephric carcinoma. Here, we report a case of 40-years-old hysterectomised female who presented in the hospital with nodular growth on the vault and complaints of bleeding per vaginum. Microscopy of the lesion did not show typical morphology of mesonephric carcinoma, but immunohistochemistry played a vital role in the diagnosis of this rare tumor.
