외이도 진주종과 동반된 연골양 한관종 1예

Chondroid syringoma, or mixed tumor of the skin, is a benign neoplasm of sweat gland origin that occurs most frequently in the head and neck. The most common sites are the nose, cheek, upper lip, scalp, forehead, and chin. The tumor typically presents as a slowly growing, painless intradermal or subcutaneous nodule in patients between the ages of 20 and 60 years. In the head and neck it occurs twice as commonly in males as in females, but no predilection for sex is observed when it develops at other sites because of a rare possibility of malignant transformation. Total surgical excision remains the best therapeutic option to avoid tumor recurrence and close follow-up observation is recommended. We report a very rare case of chondroid syringoma accompanied by cholesteatoma in a 49-year-old man who presented as a external auditory canal mass with a brief review of lit-eratures.
