Conclusion: This is the first report of cases of oncocytic metaplasia of the nasopharynx in Korea. Objective: Angiokeratoma is a rare cutaneous lesion. Mucosal involvement is occasionally found as part of a more generalized cutaneous disease. Isolated angiokeratoma in the oral mucosa is extremely rare with only a few cases reported thus far. Method: We report the case of a 61-year-old female presented with a painless lesion on the left bucal mucosa, of 4 months duration. On clinical examination, a solitary purple lesion of approximately 4 mm in diameter was found.
