Cutaneous tuberculosis: epidemiologic, etiopathogenic and clinical aspects - Part I

Abstract

Cutaneous tuberculosis (CTB) is the result of a chronic infection by Mycobacterium tuberculosis, M. ovis and occasionally by the Calmette-Guerin bacillus. The clinical manifestations are variable and depend on the interaction of several factors including the site of infection and the host's immunity. This article revises the current knowledge about this disease's physiopathology and immunology as well as detailing the possible clinical presentations.
