A Mesothelial Inclusion Cyst Presenting in a 40-Year-Old Woman as Abdominal Pain and Bloating – A Rare Diagnosis
KeywordsMesothelial inclusion cyst, benign mesothelioma, mesenteric cyst, peritoneal mesothelioma, neoplasm
Cystic mesotheliomas (also called mesothelial inclusion cysts) are rare benign neoplasms that occur more often in young women. Symptoms are usually non-specific, demanding a thorough work-up. We report a case of a 40-year-old female patient with 2 prior caesarean sections presenting with a 3-month history of abdominal pain. Laboratory tests revealed microcytic hypochromic anaemia and an elevated tumour marker CA-125. An investigation identified a large cystic abdominal mass, mostly in the left side of the abdomen. A laparotomy was performed with total resection of the lesion. Histological assessment resulted in a diagnosis of a mesothelial inclusion cyst. The patient had no recurrence after 3 years.
