Summary

Disseminated peritoneal leiomyomatosis is a rare condition involving smooth muscle tumors on the peritoneum. Early identification is crucial to prevent misdiagnosis and ensure appropriate surgical management.

Area of Science:

  • Gynecologic Oncology
  • Surgical Pathology
  • Reproductive Endocrinology

Background:

  • Disseminated peritoneal leiomyomatosis (DPL) is a rare condition characterized by smooth muscle tumors on the peritoneal surfaces.
  • Often associated with uterine leiomyomas, DPL's etiology is not fully understood but may involve metaplasia influenced by estrogen.

Observation:

  • A case of DPL was identified in a 33-year-old woman with tumors at the uterine isthmus and broad ligament.
  • Surgical resection of these tumors resulted in no recurrence at one-year follow-up.
  • Literature review identified 45 cases of DPL, noting significant variation in tumor size, number, and location.

Findings:

  • DPL tumor nodules are histologically composed of collagen fibers and smooth muscle cells.
  • The development of DPL may stem from a metaplastic process, potentially promoted by elevated estrogen levels.
  • No specific symptomatology was observed in the reported cases.

Implications:

  • Accurate intraoperative diagnosis, particularly via frozen section, is critical to differentiate DPL from peritoneal carcinomatosis.
  • Misdiagnosis can lead to suboptimal surgical strategies and potentially harmful interventions.
  • Understanding the metaplastic potential and hormonal influences on DPL can inform future management and research.
