Bacillus-Calmette-Guerin (BCG) is a live attenuated vaccine and used to prevent tuberculosis since 1921.BCG vaccination is performed as a part of expanded program of immunization (EPI). BCG vaccine is considered as a safe technique of tuberculosis prevention because there are only local adverse reactions seen with this and serious adverse reactions are rare. Lymphadenitis is the most frequent side effect of BCG vaccination. Intradermal BCG vaccination gives rise to erythromatous formation that consists of a cutaneous nodule at the site of injection and subclinical involvement of the regional lymph nodes, which is self limiting and requires no treatment. Lymphadenitis is the most frequent side effect of BCG vaccination.Fine needle aspiration is the quick, safe, and cost effective technique for diagnosis in addition to the management of BCG lymphadenitis. Here we report a case of 10-months' healthy male patient with left axillary lymphadenitis post BCG vaccination.
