Tuberculosis of the hand.

There has been recent interest in tuberculosis of the hand because of a rising incidence owing to increasing numbers of immigration, an aging population, and immunosuppressed people including affected patients with human immunodeficiency virus. In this article, we review the epidemiology, bacteriology, pathophysiology, diagnosis, and principles of treatment of tuberculosis of the hand. The second part of the report emphasizes the classification of hand tuberculosis (cutaneous lesions, tenosynovitis, bursitis, osteomyelitis, arthritis, and tuberculous hypersensitivity reactions) along with the classic presentations of each of these hand lesions.
