Disseminated Papules and Pustules with Lymphadenitis after Bacillus Calmette-Guerin Vaccination in an Infant / 대한피부과학회지

ABSTRACT

Bacillus Calmette-Guerin (BCG) is the live attenuated strain of Mycobacterium bovis that produces resistance to tuberculosis (TB) infection. BCG vaccination may induce various dermatologic complications. A 3-month-old infant who had BCG vaccination a month after birth developed erythematous papules and pustules on the trunk and both extremities. The biopsy from the left leg showed a granulomatous lesion. Acid fast staining and nested TB polymerase chain reaction (TB-PCR) were negative. A tuberculin skin test and an interferon-gamma release assay also revealed a negative result. A painful mass was noted on the left axillary area with a positive-nested TB-PCR and surgical excision was performed. The skin eruptions improved after 2 months of anti-tuberculosis medication. Herein, we report a case of disseminated papules and pustules with lymphadenitis after BCG vaccination.
