We report a case of combined nevus which showed features of common blue nevus and dysplastic nevus in a 59-year-old man. To our knowledge, such a case has not been reported in the literature. He had a 3×2cm sized, dark blue nodule on the nose. Histopathologic findings showed prominent lentiginous proliferation of nevomelanocytes associated with nests along the junction and extension down the hair follicles. Cytologically, only minority of melanocytes had irregularly shaped, large, hyperchromatic nuclei. There were many elongated melanocytes in the dermis. No recurrence was seen during one and half years follow-up period after excision and skin graft of the lesion. (Korean J Dermatol 2000;38(5)：674~676)
