(9) Mixed tumor of the minor salivary glands affects mostly patients in their fourth to sixth decades, with a predominance of females.
Pleomorphic adenomas come in the differential diagnosis of chondroid syringomas but in contrast to those syringomas arise from sweat glands.8 Based on the histopathological differences chondroid syringomas have eccrine and apocrine variants.9 Mills reported that mixed tumors are monoclonal neoplasms with replicating cells that can differentiate towards mesenchymal or epithelial components and this accounts for the histological differences of the mixed tumor of the skin.10 The treatment of choice for chondroid syringoma is wide surgical excision.11 Because of the lobulated nature of the tumor, the margins of the normal tissue should also be included with the excision to ensure complete removal of the tumor.11
It usually occurs in middle aged and elderly patients.1 It was described by Billorth in 1859 for a group of tumours of the salivary gland that contained varying amounts of mucoid and cartilaginous material.2 Virchow and Minssen at referred to them as mixed tumors with both epithelial and mesenchymal origins.3 We present a rare case of chondroid syringoma on the face of a young male.

Malignant mixed tumor (MMT) is an exceedingly rare cutaneous adnexal carcinoma with a significant risk for aggressive behavior and a propensity for metastasis.
The reading of the slides was accomplished with a light microscope (ZEISS--I Model AXIO Imager A1) and enabled the lesions to be classified as benign (adenoma and benign mixed tumor) or malignant (simple and complex carcinoma).
They are commonly found alone or in association with one of the numerous other mixed tumors or dental abnormalities.
