Leiomyomas are benign uterine smooth muscle neoplasms with varied morphology that are well known to undergo secondary changes. Cotyledonoid dissecting leiomyoma is a rare and distinct form of leiomyoma that poses a diagnostic challenge for clinicians, radiologists, and pathologists and can be confused with malignant uterine neoplasms. Only a few cases have been reported so far in the literature. Here we report a case of a cotyledonoid dissecting leiomyoma in a 60-year-old woman, emphasize its gross and histological features, and provide a review of the literature.
