Abstract:  We present a 16-year-old girl with tuberculosis of the lungs, lymph nodes, and liver, who had extensive inflammatory lesions with pustules, which resembled psoriasis. A skin biopsy showed extensive tuberculoid granulomas surrounding hair follicles, consistent with lichen scrofulosorum. Antitubercular therapy led to resolution of skin lesions. This severe inflammatory type of lichen scrofulosorum is extremely rare.
