Disseminated peritoneal leiomyomatosis (DPL) is a very rare benign disease, characterized by multiple solid subperitoneal or peritoneal smooth muscle nodules in abdominopelvic cavity and malignant transformation is extremely rare. Also, uterine smooth muscle tumors of unknown malignant potential (STUMP) is a rare tumor, which is regarded as subclassification in uterine smooth muscle tumors between benign and malignant criteria. Pathogenesis of DPL is uncertain, but increasing evidence of iatrogenic cause including laparoscopic myomectomy has been reported. We report a case of a 28-year-old female with previous history of laparoscopic myomectomy diagnosed with DPL with atypical feature and concurrent uterine STUMP using computed tomography (CT) and magnetic resonance imaging (MRI), as well as present a review of the literature.
