Lichen planus pemphigoides (LPP) is a rare autoimmune subepidermal blistering disease characterized by the coexistence of both lichen and either bullous pemphigoid or mucous membrane (MMP) features. Frontal fibrosing alopecia (FFA) scarring alopecia, generally considered form planopilaris. We report two patients with concomitant FFA MPP. Patient 1 was 73-year-old woman clinical histological diagnosis oral planus. In addition, she presented alopecic plaques in parietal area blisters, immunohistologically compatible Brunsting-Perry pemphigoid, variant MMP. During follow-up, patient also developed FFA. 2 70-year-old history ocular inflammation desquamative gingivitis, who diagnosed MMP based on conjunctival biopsy. She had features ELISA frontal biopsy confirmed diagnoses conclusion, we associated FFA, discuss whether this association new LPP an incidental finding.
