A Painful Perineural Infiltrate
A 64-year-old Caucasian man with a history of multiple skin cancers, including a recent diagnosis of microinvasive well-differentiated squamous cell carcinoma (SCC) of the lower lip, presented for Mohs surgery. He complained of dysesthesia, including tingling of the lip. Physical examination yielded a crusted papule at the vermillion border that was clinically attributed to previous biopsy site changes.
