Endometrioid Carcinoma and Ectopic Pregnancy Coexisting in an Ovarian Endometrioma

ABSTRACT A 28 years old female presented to our OPD with the complaints of inability to conceive for the last 13 years and a lump in abdomen for the past month. Perspeculum examination revealed a healthy cervix and vagina and a per-vaginum examination revealed a uterus that was normal in size but a lump was palpable in the right adnexa. There was no cervical motion tenderness. Routine investigations were normal. Ultrasonography showed a complex right-sided adnexal mass of 165 by 78 mm with heterogenous echotexture. Tumor markers were within normal range except serum β-hCG, which was raised. Urine pregnancy test was positive. CT scan reported a welldefined large solid-cystic moderately enhancing pelvic mass with internal septations, seemingly arising from right adnexa. The patient was taken up for a staging laparotomy. Peroperatively, the picture was suggestive of a chronic ectopic pregnancy. Histopathological analysis from the lesion showed an ovarian endometrioid carcinoma and ectopic pregnancy coexisting in the endometrioma complete surgical staging was done, followed by chemotherapy. The patient has responded well to the treatment.
