Lichen planus pemphigoides in an indian female

Lichen planus pemphigoides is a rare, controversial disease which is thought by majority to be a concurrence of bullous pemphigoid (B P) and lichen planus (LP) with clinical, histological and immunological features suggestive of both. We describe LP pemphigoides in an Indian female who had classical LP with subsequent short lived bullous eruption over the lesions of LP and the normal skin. DIF of the bulla showed C3 and lgG along the basement membrane zone ( BMZ) linearly. She responded successfully to systemic steroids (short course of 6 wks prednisolone 40 mg/day for 6 weeks) and dapsone 100mg per day.
