Mycobacterial Infections in the Hand and Wrist.

Mycobacterial hand infections are uncommon. These infections have an indolent course and are marked by variable and nonspecific presentations, often leading to diagnostic and treatment delays. The pathogens involved in mycobacterial hand infections include Mycobacterium tuberculosis complex, atypical mycobacteria, and M leprae. Initial treatment involves a combination of long-term antibiotics and surgical debridement to cure the infection. Reconstructive procedures aid in restoring hand function lost secondary to the disease.
