Abstract
Benign Multicystic Peritoneal Mesothelioma (BMPM) is an uncommon lesion of the serosal membranes. Many terms used in the literatures to describe this particular entity. There are larger series reported from pathologist consultation files with patients from different institutions with incomplete clinical information and lack of long-time follow-up data. Therefore, this disease is classified as an exceedingly rare medical entity. We reported two cases with such rare entity of BMPM admitted and managed in our pediatric surgery unit with a review of the literature.
Case 1: A 4 years old male was admitted to our pediatric surgery unit with a preliminary diagnosis of appendicitis. For 15 days prior to admission, he had been complaining of a crampy abdominal pain, episodes of non-bilious vomiting, progressive abdominal distention and constipation. The patient was operated with a supraumbilical transverse incision. Operation revealed a cystic mass filled with dark brown-dark green serous fluid, which was attached to the greater curvature of the stomach.
Case 2: A 28-month-old male presented with a few days history of abdominal pain, mild fever with twice episodes of non-bilious vomiting. The CT images confirmed the sonogram studies. The patient was operated with a supraumbilical transverse incision. Operation revealed a cystic mass filled with dark brown-dark green serous fluid, which was attached to the greater curvature of the stomach. In both case the histopathology an Immunohistochemistry revealed and confirmed BMPM. Benign multicystic mesothelioma should be kept in mind as an unusual cause for an abdominal mass in children.
