title: Lipid cell tumor of the ovary: steroid hormone secretory pattern and localization using 75Se-selenomethylcholesterol.
abstract: Ovarian lipid cell tumors are rare and can be difficult to localize by conventional means. We report a postmenopausal patient where rapid progression of symptoms and very high sebum levels suggested the presence of such a tumor which could not be visualized by computed tomography or ultrasound. Localization was accomplished noninvasively using 75Se-selenomethylcholesterol. Peripheral and ovarian vein steroid concentrations suggest that the tumor produced androgens preferentially by way of the delta 4 steroidogenesis pathway.
