Anastomosing Hemangioma of Ovary with Stromal Luteinization Masquerading as Sex Cord-Stromal Tumor on Intraoperative Consultation.

Anastomosing hemangiomas (AHs) are benign vascular tumor with rare occurrence in the ovary and the majority being asymptomatic. We report one such case of AH with stromal luteinization. A 35-year-old female had complaints of abdominal pain and heavy menstrual bleeding for 2 years. Her lactate dehydrogenase was markedly raised. Following the clinical suspicion of germ cell tumor, exploratory laparotomy and right salpingo-oophorectomy were done. On frozen section due to extensive stromal luteinization, diagnosis of sex cord-stromal tumor was suggested. However, the case was finally diagnosed with AH with extensive stromal luteinization. This case highlighted the potential mimics of AH due to coexistent raised biomarkers and secondary changes, thereby posing a diagnostic dilemma on intraoperative consultation.
