Benign multicystic peritoneal mesothelioma (BMPM) is a rare tumor of slow growth, with low malignant potential and which is part of the differential diagnosis of pelvic cysts. We described a case report: 55 years old woman, asymptomatic, with ultrasonographic findings of multicystic pelvic image, submitted to exploratory laparotomy and, at the inventory of the cavity, multiple cysts were present, adhered to the omentum. Omentectomy and resection of the cysts was performed followed by complete hysterectomy and bilateral oophorectomy and salpingectomy. Macroscopic examination of the surgical specimen revealed a cystic lesion with translucent content and histological features compatible with BMPM. In the immediate postoperative period, the patient developed vasomotor symptoms secondary to hypoestrogenism, which ceased spontaneously. She underwent a new surgical approach for recurrence after two years. Since the pathogenesis and etiology of BMPM are not well defined, it is very important to describe clinical practices, to better understand the diagnosis, prognosis and management of this disease.
