Abstract:
A nevus which is a benign melanocytic neoplasm rarely occurs within the external auditory canal (EAC). A dysplastic nevus presents atypical features both clinically and histologically, and is important as a potential precursor for melanoma. We present a case of a 33-year-old female patient with a dysplastic nevus in her EAC. Physical examination revealed a protruding mass arising from the posterior wall of the left cartilaginous EAC. The mass showed clinically characteristic findings of a melanocytic nevus. The patient underwent excisional biopsy via a transcanal approach under local anesthesia. Histopathological examination revealed an intradermal nevus with atypical melanocytes without pleomorphism. There was no evidence of recurrence two years after surgical excision.
