Disseminated peritoneal leiomyomatosis following laparoscopic myomectomy: a case report

Disseminated peritoneal leiomyomatosis (DPL) is a rare benign disease characterized by tumors derived from smooth muscles throughout the abdominal cavity. DPL has been reported following laparoscopic myomectomy or hysterectomy; however, few reports have described DPL after abdominal myomectomy or hysterectomy. In the present case, two intra-abdominal masses were incidentally discovered on imaging during a routine medical checkup of a 45-year-old woman who had undergone laparoscopic uterine myomectomy 10 years previously. The masses were later found to be near the ascending colon and between the liver and right kidney. A malignancy or stromal tumor was suspected, and the patient underwent exploratory surgery. Histopathologic examination revealed that the masses were leiomyomas. Considering the patient’s history of gynecologic surgery, we believe that this was a rare case of DPL following laparoscopic uterine myomectomy.
