Abstract
We report herein on a patient with a bulky nevus cell nevus in the external auditory canal. A 43-year-old woman had a feeling of fullness in the right ear and noticed a tumor in the right external auditory canal. When the patient was first seen, a pedunculated mass lesion located at the base of the entrance to her right external auditory canal was found. As its appearance was skin-colored, it was difficult for us to make a diagnosis of nevus cell nevus at first view. It was diagnosed as a dermal nevus by a dermatologist at our hospital. We decided on the course of treatment after receiving advice from a dermatologist, and removed it surgically. Dermal nevi should be resected because of their potential for malignant change for cases and locations in which careful observation is difficult, such as in the external auditory canal.
