Lichen planus pemphigoides (LPP) is thought to be a rare variant of bullous pemphigoid (BP). It is characterized by bullous lesions arising on lichen planus papules and on clinically uninvolved skin. It is reported that lichen planus pemphigoides is induced by numerous medications including the following: cinnarizine, captopril, ramipril, simvastatin, PUVA, and antituberculous medications. Some cases of LPP demonstrate overlapping characteristics with paraneoplastic pemphigus (PNP) and have been associated with internal malignancy.
