title: Sarcoidosis: unusual cause of a rectal mass.
abstract: We have reported the case of a patient who had a rectal mass 3 years after the diagnosis of sarcoidosis. A malignancy was suspected, but biopsy of the rectal mass showed epithelioid granulomas with giant cells, consistent with sarcoidosis. Therefore, sarcoidosis should be considered as a rare cause of a rectal mass.
