Perianal tuberculosis. A case report

The case is described of a 36 years old man with anorectal tuberculosis. Of patients with pulmonary tuberculosis, 0.8% will develop intestinal lesions: and of these, only 1% will present perianal tuberculosis. The infection occurs mainly in patients with primary pulmonary lesions, and is caused by swallowing sputum. The mycobacterium penetrates the perianal region through microerosions and fissures. Thus, the association of pulmonary with anal tuberculosis is well established, and any patient having a pulmonary focus and complaining about perianal pathology should be suspected of having perianal tuberculosis.
