Lipid Cell Tumors in Two Women With von Hippel-Lindau Syndrome

Abstract

Lipid-cell tumors are rare, functioning ovarian neoplasms. They have not been reported in women with von Hippel-Lindau syndrome, an autosomal-dominant tumor-suppressor gene mutation that is associated with renal cell carcinoma, and other vascular tumors. Two women with von Hippel-Lindau syndrome and kidney tumors were evaluated for secondary amenorrhea, hirsutism, and complex adnexal masses seen on computed tomography. The first patient had known renal cancer and bilateral adnexal masses, one with central necrosis. Because metastatic renal cell cancer could not be excluded on frozen section, bilateral salpingo-oophorectomy was performed. The second patient underwent right salpingo-oophorectomy after human chorionic gonadotropin testing confirmed that the ovarian tumor produced testosterone. Final pathology in both cases revealed testosterone-secreting lipid cell tumors. Lipid cell ovarian tumors should be considered in women with von Hippel-Lindau presenting with adnexal mass, amenorrhea, and hirsuitism.
