Basosquamous cell carcinomas (BSCs) are very rare and behave aggressively, with features of both basal cell carcinoma and squamous cell carcinoma. The diagnosis of BSC includes a spectrum of histologic definitions, ranging from coexistence of basal cell carcinoma and squamous cell carcinoma with or without a transition zone, to any basal cell carcinoma with evidence of keratinization.A 63-year-old man presented with a BSC within a chronic periorbital wound, which was confirmed through a postoperative histologic examination. The wound was created from a previous laser ablation of a diagnosed basal cell carcinoma. The BSC was excised without causing any deformity, and coverage of the defect was obtained using a local perforator-based flap. No recurrence was observed during a 5-month follow-up.
