title: Facial localization of malignant chondroid syringoma: a rare case report.
abstract: First described by Hirsch and Helwig in 1961, chondroid syringomas (CSs) are rare, benign tumors of the skin arising from the eccrine sweat glands with tumor differentiation in the epithelial and mesenchymal tissues. They most commonly occur in the head and neck, although they may be also found in the axilla, trunk, limbs, and genitalia. The incidence of CS is <0.01% of all primary skin tumors. Malingnant chondroid syringomas (MCS), which are also called malignant mixed tumors of the skin, are extremely uncommon. MCSs commonly involve the limbs and rarely head and neck. In this article, we present a case of malignant chondroid syringoma localized in the face at the left nasolabial region in the light of literature review.
