A Generalized Form of Lichen Planus Pemphigoid Induced by an Oral Antidiabetic.

Lichen planus pemphigoid (LPP) is a rare autoimmune bullous dermatosis, although it is frequently idiopathic, the induced form is rare and there are few inducing drugs. We report a case of LPP induced by a gliclazide. A 68-year-old female patient with type 2 diabetes on gliclazide for three months presented with an eight-week history of generalized erythematous-papular eruption. Then she developed blisters on her forearms with oral mucosa involvement. A diagnosis of gliclazide-induced LPP was made based on a skin biopsy and imputability. The patient was treated with systemic corticosteroid with an improvement. LPP is a rare entity; its diagnosis is a challenge as it represents an overlap between lichen planus and bullous pemphigoid.
