Background: Pemphigus vulgaris is an autoimmune intraepithelial bullous disease involving the skin and the mucous membranes. Imiquimod, a topical therapy for skin basal cell carcinoma, is an amine that induces the production of tumor necrosis factor alfa, interleukin-1 and other cytokines. Pemphigus induced by drugs has been frequently reported, mostly after systemic therapy.
Case Presentation: We present the case of a 50-year-old man who developed skin, intraoral, and genital mucosae lesions 3 days after a treatment with Imiquimod for multiple superficial basal cell carcinoma of the trunk. Direct and indirect immunofluorescence results were compatible with the diagnosis of pemphigus vulgaris. Enzyme-linked immunosorbent assay was negative for desmoglein 1 and 3, but interestingly, by immunoblotting on keratinocyte extracts a band of 170 kDa was obtained by IgG. The patient, after interrupting Imiquimod application, started a treatment with prednisolone and in 4 weeks showed a complete remission.
Conclusion: Topical Imiquimod therapy might induce atypical pemphigus vulgaris in some patients.

This study aims to explore the measurement agreement between direct and indirect health utility measures in four chronic dermatological conditions (atopic dermatitis, hidradenitis suppurativa, pemphigus, psoriasis). Outpatients survey data collected between 2015 and 2021 were analysed. Health-related quality of life (HRQoL) outcome measures included time trade-off (TTO), EQ-5D-5L and Dermatology Life Quality Index (DLQI).

Pemphigus vulgaris (PV) is a subtype of pemphigus and life-altering disorder that results in the formation of intraepithelial blisters in mucosa and skin. Though the etiology is not well understood, it is an autoimmune disorder resulting in acantholytic blisters due to auto-antibodies targeting proteins of keratinocyte adhesion. Rapid diagnosis and restoration of the epidermal layer is imperative for patients with PV as widespread epidermal damage can lead to high morbidity and mortality rates.
