Abstract
A 66-year-old female patient presented with blisters on the scalp and neck for 1 month. She had a history of type 2 diabetes for 6 years, and started taking the dipeptidyl peptidase-4 inhibitor linagliptin at a dose of 5 mg once a day 6 months before the onset of eruption. Skin examination showed scattered mung bean- to peanut-sized blisters on the scalp, and some blisters broke with exudation and crusts. There was a pigeon egg-sized bulla and two mung bean-sized blisters on the left neck, with tense blister walls, clear blister fluids, non-erythematous base, and Nikolsky′s sign was negative. Enzyme-linked immunosorbent assay revealed that the serum levels of anti-BP180 NC16A and anti-BP230 antibodies were 5.81 and 139.76 kU/L respectively. Histopathological examination of the blister on the neck showed subepidermal blister formation, and infiltration with neutrophils and a few eosinophils in the blister. The patient was finally diagnosed with localized anti-BP230-type bullous pemphigoid. This case of anti-BP230-type bullous pemphigoid associated with the dipeptidyl peptidase-4 inhibitor linagliptin was firstly reported in China.
