Abstract

PURPOSE: Chondroid syringoma, previously known as 'mixed tumor of the skin', is a rare benign tumor. It usually presents an asymptomatic solitary firm intradermal or subcutaneous slowly growing nodule. It occurs frequently in the head and neck region of middle-aged men. We would like to report an uncommon chondroid syringoma about the clinical and histologic presentation. about the clinical and histologic presentation.
METHODS
We experienced two cases of chondroid syringoma on the nose and the upper lip, each other. Both masses were totally excised with clear margin.
RESULTS
On histologic examination, the masses showed a biphasic pattern-an epithelial component exhibiting apocrine/eccrine differentiation and a stromal component exhibiting myxoid/collagenous change-consistent with the diagnosis of chondroid syringoma. There have been no evidence of recurrence and malignant transformation during postoperative follow-up.
CONCLUSION
There is no one distinctive clinical feature that is specific for chondroid syringoma. However, it should be included in the differential diagnosis of a solid nodule in head and neck region with long standing duration, such as epidermal inclusion cyst, pilomatrixoma, dermoid cyst, sebaceous cyst, neurofibroma, and basal cell carcinoma.
