Leiomyomatosis peritonealis disseminata mimicking peritoneal carcinomatosis 13 years after laparoscopic uterine myomectomy: A case report.

INTRODUCTION

Leiomyomatosis peritonealis disseminata (LPD) is a rare clinical condition that can be challenging to diagnose because its clinical features mimic other conditions. We present a case of LPD mimicking peritoneal carcinomatosis 13 years after laparoscopic uterine myomectomy using a power morcellator. The aim of this paper is to report a rare case which surgeons can learn from and to provide more clinical information for further studies to investigate LPD.

PRESENTATION OF CASE

A 49-year-old woman was referred to us because sonography revealed abnormal abdominal and pelvic nodules. Thirteen years previously, she had undergone laparoscopic uterine myomectomy using a power morcellator. An exploratory laparotomy revealed nodules on the peritoneum, greater omentum, intestinal mesentery, and terminal ileum. We surgically removed all visible nodules and performed bilateral salpingo-oophorectomy. LPD was confirmed based on the morphology and immunohistochemistry results.

DISCUSSION

Diagnosing LPD preoperatively may be difficult because its clinical manifestations resemble peritoneal carcinomatosis or metastatic lesions. Abdominal pain due to diffuse tumor growth is a common manifestation. LPD degenerating into malignancy is rare, but possible. The probable etiological factors, clinical manifestations, and treatment options which may aid when dealing with LPD have been described in this report.

CONCLUSION

LPD should be considered in women, particularly those with a history of gynecologic surgery presenting with disseminated intraabdominal or pelvic tumors.
