A 40-year-old man presented to the clinic for evaluation of a 1.1-cm blue papule on his right nares. The lesion had been present for 20 years, but he sought treatment now at the urging of his wife. There was no pain, pruritus, or burning. Dermatoscope examination demonstrated a uniform, steel-blue pattern of pigmentation. The otherwise healthy patient had no personal or family history of similar lesions.
The patient, a 45-year-old woman, was concerned about a 4- to 6-mm purple papule on her lower lip. She could not remember how long the lesion had been present. When pressure was applied during diascopy, the lesion blanched fully. No other lesions were found on examination. Although the papule was asymptomatic, the patient wanted to have it removed for cosmetic reasons.
