A 70-year-old Italian man presented with a 6-month history of a deep ulcerative lesion involving his left nasal ala after use of a nasal canula during a recent hospitalization. The lesion failed to heal and gradually expanded. At presentation, the patient was noted to be missing approximately half of the left nasal ala. In its stead, there was erosion surrounded by hemorrhagic crusting and an approximately 4-cm margin of mild erythema and edema over the left cheek. The erosion was indurated but nontender. At the left angle of the mouth, a 1.5 × 1.0-cm slightly waxy plaque with focal crusting was found. The nares appeared to have some mucosal inflammation. No lymphadenopathy was present. (Figure 1).
