Abstract

A rare case of primary rectal tuberculosis presented as a rectal mass, indistinguishable clinically and radiologically from advanced
rectal carcinoma . Histology failed at first to identify granulomas, acid fast bacilli, or malignancy, but subsequent biopsies showed
multiple epithelioid granulomas with caseating necrosis and Langhans giant cells. Given these findings and the high regional
incidence of tuberculosis, presumptive diagnosis was given and anti-tubercular drugs were initiated followed by resolution of the
mass and symptoms.
