Abstract

Background and Objective: Primary fallopian tube carcinomas (PFTC) are rare tumors with non-specific clinical presentations. The current case was unique since the tumor was first detected on endometrial curettage and clinicoradiologically was misdiagnosed as endometrial carcinoma.
Case Report: A 48-year-old, post-menopausal female presented with one episode of vaginal bleeding. Endometrial curettage showed poorly differentiated carcinoma, while cervico-vaginal Papanicolaou (Pap) smear was negative for malignant cells. Right sided fallopian tube carcinoma in-situ was diagnosed on histopathological examination of surgical hysterectomy with B/L salpingo-oophorectomy specimen.
Conclusion: As observed in the current case, unusual tumor histology with broad papillary fronds lined by pleomorphic cells showing nuclear stratification and focal involvement of endometrial curettage specimen may be considered a useful pointer for tubal malignancy.
