A Case of Chondroid Syringoma with Folliculosebaceous-Apocrine Differentiation / 대한피부과학회지

ABSTRACT

Chondroid syringoma is a sweat gland tumor which is composed of a mixture of epithelial cells and mesenchymal tissue. It is referred to as a mixed tumors. Mixed tumor with follicular, sebaceous and apocrine differentiation are considered to be an expression of the common embryologic origin of elements of the folliculosebaceous-apocrine unit. A 74 year-old man presented with an asymptomatic, firm, pigmented nodule on the right cheek. Histologically, it showed numerous aggregates of cuboid epithelial cells with tubuloalveolar structures and keratinous cysts within a chondroid stroma. This was consistent with a chondroid syringoma. We herein describe an unusual chondroid syringoma with folliculosebaceous-apocrine differentiation.
