Bilateral Bacilli Calmette–Guérin-induced lupus vulgaris.

Abstract: A 9-month-old female child was brought with a history of asymptomatic lesions on the upper arms, at the site of Bacilli Calmette–Guérin (BCG) injections. The lesions were painless but slowly progressive. On examination, there were two erythematous plaques on either arm, with central atrophy and a scaly border. The diascopy test was positive. Mantoux test was positive, while histopathology showed tuberculoid granulomas. Culture was negative. A diagnosis of BCG-induced lupus vulgaris was made and the patient was started on two drug regimens of rifampicin and isoniazid with good response. [Copyright &y& Elsevier]
