title: A case of Basal cell carcinoma of external auditory canal.
abstract: Malignant tumor originated from external auditory canal (EAC) is very rare with an annual incidence of around 1 per million. Pathologically, squamous cell carcinoma is incidentally most common, and adenoid cystic carcinoma, basal cell carcinoma, and melanoma follow in decreasing order. Due to the rarity of malignant tumor of EAC, there is no widely accepted treatment modality yet. But basal cell carcinoma, known to be less aggressive tumor, can be removed with a minimal safety margin and have better treatment results. Recently we experienced a case of basal cell carcinoma in the EAC, confined in the cartilaginous portion of EAC, presenting with intermittent otorrhea for several years. The patient was treated with a sleeve resection of the EAC with a safety margin reconstructed with a split-thickness skin graft. No tumor recurrence or complication was noted in the first postoperative year.
