Disseminated cutaneous BCG infection following BCG immunotherapy in patients with lepromatous leprosy.

Abstract

Cutaneous complications of Bacillus Calmette-Guerin (BCG) vaccine, especially in the form of generalised disease, are uncommon and mostly occur in immunocompromised individuals. There is a paucity of data on the cutaneous adverse reactions secondary to BCG immunotherapy in leprosy. We report two unique cases of disseminated cutaneous BCG infection following immunotherapy in patients with lepromatous leprosy. To our knowledge, cutaneous BCG infection presenting as widespread lesions after immunotherapy and confirmed by isolation of Mycobacterium bovis by polymerase chain reaction (PCR) has not been described. A high index of suspicion is required when leprosy patients who receive BCG immunotherapy develop new lesions that cannot be classified as either reaction or relapse, and diagnosis may be confirmed on histopathology and PCR.
