Xanthogranulomatous oophoritis with Leydig cell hyperplasia masquerading as ovarian neoplasm - A case report

Xanthogranulomatous oophoritis is an uncommon form of chronic inflammation of the ovary. Its clinical manifestations, imaging findings, and gross picture can mimic an ovarian neoplasm. Hilar cells, which are morphologically difficult to distinguish from testicular Leydig cells, secrete testosterone and they are mostly seen in the ovarian hilum. They can undergo hyperplasia or can transform into a tumor. We present a case of xanthogranulomatous oophoritis with Leydig cell hyperplasia, which mimicked an ovarian neoplasm.
