This case report describes a 32-year-old woman presenting with primary infertility who was initially diagnosed with stage III ovarian cancer based on laparoscopic findings of a diffuse peritoneal process and bilateral ovarian lesions. Surgical intervention revealed an unusual pathological triad consisting of leiomyomatosis peritonealis disseminata, endometriosis, and multicystic mesothelioma, marking the first known simultaneous occurrence of these three distinct conditions. The authors note that while endometriosis is frequently associated with either leiomyomatosis peritonealis disseminata or multicystic mesothelioma individually, this specific combination has not been previously documented in medical literature. This paper is centrally about endometriosis — specifically its rare co-occurrence with leiomyomatosis peritonealis disseminata and multicystic mesothelioma in a single patient.

Abstract

A 32-year-old, previously healthy woman with a diffuse, complex tumoral process is described. While she was being evaluated for primary infertility, a laparoscopic procedure revealed a disseminated peritoneal process associated with bilateral ovarian lesions. A clinical diagnosis of stage III ovarian cancer was made and total hysterectomy, bilateral salpingo-oophorectomy, and omentectomy were performed. Pathologic studies showed an admixture of leiomyomatosis peritonealis disseminata (LPD) endometriosis, and an extensive multicystic mesothelial proliferation. Although endometriosis is known to occur in conjunction with either LPD or multicystic mesothelioma, to our knowledge this is the first report of all three lesions occurring simultaneously.
