An 85-year-old woman presented with a 5-year history of a slowly enlarging, reddish brown, subcutaneous mass on the left nasal ala (Figure 1). The mass was painless but had been causing mild nasal obstruction over the past year. The patient had a remote history of mild facial trauma but denied having any fevers, drainage, or radiation exposure. The findings of biopsies performed by several specialists years earlier were nondiagnostic.
