A Case Report of Tuberculosis in the Finger

Tuberculosis is a chronic, infectious disease that predominantly affects the respiratory system. Of the least common extrapulmonary forms of the disease is cutaneous tuberculosis. We present an unusual case, which is of cutaneous tuberculosis in the finger, manifesting as an ulcerating, erythematous lesion. This had later spread to the adjacent soft tissue and bones, causing osteomyelitis of the phalanges. It is important that physicians maintain a high index of suspicion when faced with atypical skin lesions to avoid the sequelae of the local and disseminated spread of a tuberculosis infection.
