The size of this lesion usually ranges between a few centimeters and 10 cm. It is usually asymptomatic but occasionally presents with various non-specific symptoms which makes correct pre-operative diagnosis difficult. We present a case of a giant peritoneal simple mesothelial cyst that was successfully managed by complete surgical excision which is the treatment of choice. Case presentation A 21-year-old Caucasian Moroccan woman with vague abdominal discomfort and associated distention during the previous 2 years without other symptoms presented to our hospital. Her past medical history was unremarkable. On physical examination a mobile painless and relatively hard abdominal mass was palpated. The laboratory examination and abdominal radiograph were unremarkable. Abdominal radiologic imaging showed a cystic mass of 35 X 20 X 10 cm that occupied the entire anterior and right abdominal cavity. Radical excision of the cyst was performed by midline laparotomy without any damage to the adjacent abdominal organs. The histopathological diagnosis was simple mesothelial cyst. The postoperative course was uneventful with no recurrence. Conclusion A peritoneal simple mesothelial cyst is a quite rare abdominal tumor that must always be considered in differential diagnosis of pelvic cystic lesions and other mesenteric cysts. The treatment of choice is the complete surgical excision of the cyst. Introduction According to Perrot classification the peritoneal simple mesothelial cyst PSMC benign cystic mesothelioma and malignant
