Brunsting-Perry Type Pemphigoid Causing Secondary Cicatricial Alopecia in 2 Patients.

Brunsting-Perry type pemphigoid (BPP) is a rare subepidermal blistering disease and a cause of secondary cicatricial alopecia. It was originally described by Brunsting and Perry in 1957 as a rare variant of cicatricial pemphigoid, characterized by bullous lesions limited to the head, neck, scalp, and upper trunk with mild or no mucosal involvement. We report 2 cases of BPP cicatricial alopecia with histopathology of subepidermal blister formation, different clinical presentation, and different salt-split test results.
