A 73 year-old man presented with a large ulcerated plaque almost completely covered with a thick hemorrhagic black crust on the left temporal area, which was slowly growing for over 10 years (Fig. 1a, b). The patient had signs of chronic sun damage and had been previously treated for multiple actinic keratoses. Previous medical history included a cardiac arrhythmia, for which the patient was treated with acetylsalicylic acid 100 mg/day. An incisional biopsy confirmed the diagnosis of basal cell carcinoma (BCC), and the patient is scheduled for surgical treatment.
