Coexistence Of Squamous Cell CarcinomaWith Dermoid Cyst Of Ovary:A Case Report

Abstract

Ovarian squamous cell carcinoma is a rare malignancy and the occurrence is attributable to malignant transformation of an existing ovarian dermoid cyst. The de novo occurrence of squamous cell carcinoma of the ovary, in the absence of an antecedent ovarian dermoid, is extremely rare. A 40- years- old female presented with pain and enlargement of abdomen since last 4 months. A mass was felt over right iliac fossa. Ultrasonography showed partly cystic and solid area in mass arising from ovary. A tooth- like structure was also seen. Dermoid cyst was the diagnosis offered. Laparotomy was performed. Ovarian mass with hair, a tooth and putty-like material was present. Solid white area with thickened wall was found. Histopathology confirmed the findings of dermoid cyst and the thickened area showed squamous cell carcinoma with areas showing keratinous and giant cell reaction which was also seen at the periphery of tumor areas. Left ovary was normal and no deposits of tumor were seen. Postoperative period was uneventful.
