Perianal tuberculosis: A rare disease of late diagnosis

This is the authors' abstract. We don't add key points for this paper.

Tuberculosis remains a public health problem and its rare extrapulmonary forms persist with late diagnosis, which delays the diagnosis and favors the dissemination of the disease. The perianal manifestation occurs in approximately 0.7% of tuberculosis cases and usually manifests as fistulizing disease, but may also present with ulcerated lesions, with necrotic and quite painful clinical picture. Initial treatment should be carried out aimed at controlling perineal and perianal sepsis, with subsequent establishment of specific drug therapy provided by the Health Ministry.
