Leiomyomatosis peritonealis disseminata: Three case reports.

RATIONALE: Leiomyomatosis peritonealis disseminata (LPD) is a rare benign lesion primarily consisting of smooth muscle cells, which mostly affects premenopausal females. Here, we reported 3 females with LPD (age, 40-48 years) admitted for pelvic masses.

PATIENT CONCERNS: All 3 LPD cases received laparoscopic uterine fibroid morcellation at 3, 8, and 14 years ago, respectively. Two cases were admitted for pelvic masses. One case was admitted for recurrent fibroids with pollakiuria.

DIAGNOSES: LPD was considered in 2 cases preoperation according to imaging examination, and one of them received ultrasound-guided biopsy of the lesion in the right lobe of the liver. One case was considered as recurrent fibroids preoperation. After surgery, all cases were pathologically diagnosed as LPD consisting of benign smooth muscle cells.

INTERVENTIONS: A total abdominal hysterectomy, salpingo-oophorectomy, and debulking was performed for all 3 cases. Intraoperative exploration revealed that the fibroids distributed in the mesentery (3 cases), broad ligament (1 case), omentum (1 case), liver (1 case), and rectus abdominis (1 case).

OUTCOMES: No recurrence was found during postoperative following-up (5-12 months).

LESIONS: Preoperative diagnosis of LPD is presented as a challenge due to unspecific clinical manifestations. Its diagnosis mainly depends on histopathologic evaluation. Surgery still is the primary treatment for LPD. For patients without reproductive desire, total abdominal hysterectomy, salpingo-oophorectomy, and debulking can be performed, and the affected tissue should be removed as much as possible based on the risk assessment.
