Real-Life Experience with Sonidegib for Locally Advanced Basosquamous Carcinoma: A Case Series

Basosquamous carcinoma is an uncommon subtype of basal cell carcinoma (BCC), characterized by aggressive local growth and metastatic potential, that mainly develops on the nose, perinasal area, and ears, representing 1.2-2.7% of all head-neck keratinocyte carcinomas. Although systemic therapy with hedgehog inhibitors (HHIs) represents the first-line medical treatment in advanced BCC, to date, no standard therapy for advanced basosquamous carcinoma has been established. Herein, we reported a case series of patients affected by locally advanced basosquamous carcinomas, who were treated with HHIs.
