title: Solitary benign fibrous mesothelioma of the peritoneum: A rare entity in a 2-year-old child.
abstract: Solitary benign fibrous mesothelioma (BFM) is uncommon and is termed as solitary fibrous mesothelioma or localized fibrous mesothelioma. Although the most common site for its development is the pleural region (65%), it has also been reported in the peritoneum. They are mostly seen in adults (average age: 54 years). Herein, we present a case of BFM in a 2-year-old male child, who presented to our hospital with abdominal pain and a lump in the abdomen. Differential diagnosis included solitary fibrous tumor, gastrointestinal stromal tumor, and benign fibrous lesions of mesentery. Establishing a preoperative diagnosis is difficult on the basis of clinical parameters or imaging studies and final diagnosis can only be assessed based on the results of histopathological and immunohistochemical examination.
