A case report of disseminated peritoneal leiomyomatosis

Abstract

We report a rare case of disseminated peritoneal leiomyomatosis (DPL). A 57-year-old woman complaining of abdominal fullness and a mass underwent CT and MRI and was found to have intraperitoneal masses at the pelvic space. We diagnosed the case as recurrent DPL because she had undergone surgery for DPL 13 years before and we resected the masses with a part of the major omentum and ileum. Immunostaining of these specimens revealed positivity for smooth muscle actin, vimentin, estrogen receptors, and progesterone receptors. Staining results for c-kit and CD34 were negative. In view of this immunostaining appearance, we diagnosed the patient with DPL.
