An adult woman with a history of melanoma, basal cell carcinoma (BCC), and squamous cell carcinoma presented for her yearly skin evaluation. Examination showed an approximately 1-cm, shiny, pink, nodular-lobulated lesion with nonarborizing telangiectasias involving the upper chest near the neck (Figure 1). Because the clinical morphology was concerning for a BCC, shave biopsy followed by electrodessication and curettage was performed.
