Bullous pemphigoid is the most common acquired bullous disease with an autoimmune basis and a tendency to involve mostly old people. By rising incidence of diabetes all over the world, consumption of antidiabetes medications has also increased. One of the most used antidiabetes drugs is gliptin family (dipeptidyl-peptidase 4 inhibitor). Recently, this class of oral antidiabetic agents showed a correlation with the occurrence of bullous pemphigoid and its subtypes, including mucous membrane pemphigoid and pemphigoid nodularis. We are reporting a case series of 4 diabetes patients that we diagnosed with bullous pemphigoid subtypes (mucous membrane pemphigoid, pemphigoid nodularis, and its rarest subtype, linear IgA bullous dermatosis) after taking different drugs of gliptin family.
