Abstract
Introduction:
Ovarian fibrothecomas represent an ovarian stromal neoplasm developing in a wide spectrum of clinical settings. These tumors have been described as rare ovarian neoplasm, accounting for about 4% of all ovarian tumors. We report a case whose clinical presentation was highly deceptive and was clinically and radiologically diagnosed as malignant ovarian tumor. Ascitic fluid cytology revealed absence of malignant cells. On histopathological examination, it was diagnosed as benign fibrothecoma with cystic changes. Postoperative follow-up for about six months was uneventful.
Case:
A 45 year old female presented to the gynae emergency with large abdominal lump of 20 weeks size with acute pain abdomen. She was admitted for initial management and thorough evaluation. Hematological and biochemical parameters were within normal limits. USG revealed a large multilocular, predominantly cystic lesion 20.9 × 9.6 × 11.4 cm in pelvis. CECT revealed ovarian cystadencarcinoma left ovary with locoregional mass effect, mild ascites and suspicious metastasis to internal iliac lymph nodes. Radiological and preoperative clinical diagnosis was malignant ovarian tumor. Panhysterectomy and omentectomy was performed. On gross examination, a well encapsulated, multinodular cystic tumor of left ovary about 17 × 14 × 7 cm was identified. Cut surface was mostly solid with few cystic areas. Uterus, cervix, right ovary and both tubes were unremarkable. On microscopic examination, multiple sections showed spindle shaped cells in storiform and palisading pattern. No mitotic activity was identified. On special staining, it was positive for vimentin, which is a characteristic feature of ovarian fibrothecoma.
Conclusion:
The accurate preoperative diagnosis of ovarian fibrothecoma with cystic changes could have prevented the extensive surgical intervention such as bilateral salpingo- oopherectomy with hysterectomy.
