Cutaneous tuberculosis (TB) is not a well-defined entity but comprises a wide spectrum of clinical manifestations. In the past, much of the confusion regarding cutaneous TB has resulted from misleading, redundant nomenclature and cumbersome, non-clinically oriented classifications of cutaneous disease. These classifications have been based on various criteria, including chronic versus labile disease, localizing versus hematogenous disease, histologic forms of disease, immunologic status of the patient, primary disease versus reinfection, and listing of the various types of cutaneous mycobacteriosis ( 1 – 3 ). A more clinically relevant classification has been developed that uses three criteria: pathogenesis, clinical presentation, and histologic evaluation ( Table 1 ).
