A case of scrofuloderma-like BCGitis near the BCG vaccination site

Abstract

A 10-month-old male patient was seen with a nodular lesion on his left upper arm which developed several months after BCG vaccination. Physical examination revealed a bean sized, irregular surfaced, erythematous pustular nodule on the left upper arm at a place different from the vaccination site. Histopathologic examination of the nodule on the left upper arm showed tubercles composed of mononuclear cells, epithelioid cells and langhans type giant cells in the dermis. Caseation necrosis within the typical tubercles was noted. Prominent improvement of the lesion was observed 4 months after oral medication with isoniazid and rifampicin.
