Abstract
- BCG(Bacillus Calmette-Guerin) is a vaccine from living attenuated Mycobacterium bovis which produces resistance to tuberculous infection. It induces specific and nonspecific dermatologic complications on the vaccination site or out of the site. The specific reactions include lymphadenitis, scrofuloderma-like, lupus vulgaris-like, lichen nitidus-like and tuberculid. On the contrary, nonspecific reactions such as toxicoderma hemorrhagica, urticaria, erythema multiforme, erythema nodosum and granuloma annulare have also been reported. Among them the term BCGitis is used to describe the skin reaction and enlargement of the regional lymph node, with or without suppuration. We present three cases of BCGitis developed around the vaccination site after BCG vaccination with spontaneous remission within 2~6 months. Histopathologic examination respectively showed foci of palisading granuloma with central caseation necrosis and surrounding lymphohistiocytic infiltration.
