Anti-BP180-type mucous membrane pemphigoid: report of two cases

Pemphigus vulgaris and mucous membrane pemphigoid: A systematic review of clinical manifestations, diagnosis, and treatment

Pemphigus vulgaris (PV) and mucous membrane pemphigoid (MMP) are mucocutaneous autoimmune diseases characterized by blistering lesions of mucous membranes and skin, with very similar clinical manifestations. This study aimed to systematically review the literature on the clinical and demographic profile, diagnostic methods, and treatment of patients with pemphigus vulgaris (PV) and mucous membrane pemphigoid (MMP). Studies describing cases of PV and MMP diagnosed by direct immunofluorescence that exhibited intraoral manifestations were included. Thirty-two articles were included, with 18 studies on PV and 15 on MMP, corresponding to 50 and 123 cases diagnosed as PV and MMP, respectively. Most patients with PV (64 %) and MMP (81.3 %) were women in the fifth and sixth decade of life, respectively. The mouth was the primary site of involvement both in PV (71.4 %) and in MMP (91 %). The cheek mucosa and gingiva were the most frequently affected intraoral sites in PV (30 %) and MMP (64.2 %), respectively. Direct immunofluorescence was positive for IgG in all cases of the two conditions. The treatment of choice was systemic corticosteroid therapy for patients with PV (50 %) and topical treatment for patients with MMP (53.7 %). Differences in intraoral site predilection, extraoral involvement, and the results of diagnostic tests allow us to trace the clinical, demographic, and diagnostic profile of PV and MMP that contributes to differential diagnosis and therapeutic management.
