The case of a 36-yr-old woman with a pituitary adenoma who was found to have bilateral ovarian masses is reported. The right ovary was removed, measured 15 cm in maximum dimension, and contained multiple cysts which on microscopic examination had the typical morphology of follicle cysts. The left ovary was grossly similar intraoperatively. Subsequent excision of the pituitary adenoma was followed ∼3 mo later by a return to normal size of the left ovary. The case represents an example of multiple luteinized follicle cysts, analogous to the phenomenon seen occasionally in pregnancy, but with a different clinical background. Periodic documentation of this phenomenon is present in the literature, predominantly the clinical literature with limited pathologic documentation of the nature of the process in many reports. As pertains to the evaluation of follicle cysts encountered during pregnancy the differential diagnosis is with a cystic granulosa cell tumor of either adult or juvenile types, more likely the latter. The cyst lining is identical to that of standard follicle cysts and contrasts with the immature mitotically active nuclei seen in a juvenile granulosa cell tumor. That neoplasm also usually shows follicular differentiation typically absent in follicle cysts. Pathologists should be aware of the rare occurrence of luteinized follicle cysts in patients with a pituitary adenoma to enable correct intraoperative and standard pathologic evaluation.
