Peritoneal sarcoidosis that simulates peritoneal carcinomatosis: a case report.

Sarcoidosis is a multisystem inflammatory disorder of unknown cause characterized by the formation of pleomorphic, non-caseating granulomas with predominantly pulmonary involvement. Although abdominal sarcoidosis represents 30% of extrapulmonary manifestations, peritoneal involvement is extremely rare. We will describe a rare case of peritoneal sarcoidosis simulating carcinomatosis in a young patient with abdominal pain who underwent laparoscopic examination.
