title: Pemphigus foliaceus induced by rifampicin.
abstract: Pemphigus foliaceus was seen in a patient with pulmonary tuberculosis during rifampicin therapy. The skin lesions were eczematoid patches, flaccid bullae and crusted plaques on the trunk and extremities, histologically showing a high epidermal blister with acantholysis. The diagnosis was confirmed by immunofluorescent studies. After the patient discontinued rifampicin, the skin lesions cleared completely within 5 weeks without any systemic medication.
