ABS TRACT Disseminated peritoneal leiomyomatosis (DPL) are characterized by the dissemination of smooth muscle nodules throughout the peritoneal surfaces. Smooth uterine muscle tumors of uncertain malignant potential (STUMP) is also a rare situation with complicated diagnosis and treatment with similar disease presentation to DPL. Interventional procedure such as laparoscopic morcellation can disseminate small tumor pieces all around the abdominal cavity. The objective of this study is to evaluate whether imminent follow-ups are needed after laparoscopic surgeries such as morcellation to reduce disease recurrence. We discuss the case of a 43-years-old patient presented with abdominal pain who had laparoscopic myomectomy 2 years ago. A uterine mass was noted with ultrasonography and computed tomography. The pathological results of masses was reported as STUMP. For both DPL and STUMP, diagnosis and treatments are difficult and problematic. This emphasizes the importance of following up with patients after laparoscopic surgeries, especially after morcellation.
