Abstract

Malignant transformation of endometriosis is an infrequent complication. Clear cell carcinoma from endometriosis is very rare in the paraovarian cyst. To date no cases have been reported. We report a case of clear cell carcinoma arising from endometriosis of the paraovarian cyst with a brief review of literature.

Keywords: Clear cell carcinoma; Endometriosis; Paraovarian cyst.

Fig. 1
Computed tomography shows 16 cm sized huge cystic mass with small solid portion (arrow) in the pelvic cavity.
Fig. 2
Fig. 2
A unilocular cyst is seen with focal areas of solid papillary growth. The remaining internal lining surface shows areas of hemorrhage.
Fig. 3
Fig. 3
Scanning of the cyst with low magnification reveals a portion of solid growth. The cyst wall contains a smooth muscle layer and the internal surface is focally lined by cuboidal to columnar epithelium (Hematoxylin-Eosin, original magnification ×10).

Higher power magnification of the solid portion reveals tumor cells with pleomorphic nuclei and eosinophilic or clear cytoplasm arranged in tubular or acinar structures. A hobnail pattern is prominent (Hematoxylin-Eosin, original magnification ×200).
