A chondroid syringoma is a rare mixed tumor of sweat-gland origin that has both a benign and malignant form.

Benign chondroid syringoma

(57) Mixed tumor of skin is morphologically identical to pleomorphic adenoma of the salivary gland, exhibiting secondary structures such as glands/ducts, cysts, keratinous cysts, and foci of squamous differentiation, with a mucoid stroma typically showing cartilaginous metaplasia (hence also known as chondroid syringoma).

Auricular ossification has also been associated with inflammatory conditions such as chondritis, perichondritis, and syphilitic perichondritis, as well as with neoplasms such as nevi of the face, pilomatrixoma, and chondroid syringoma. (4) Finally, many systemic diseases can lead to auricular ossification, including congenital plaque-like osteomatosis, Albright hereditary osteodystrophy, fibrodysplasia ossificans progressiva, Addison disease, osseous heteroplasia, and collagen vascular diseases, especially CREST syndrome and childhood dermatomyositis.

Chondroid syringoma of the skin is nearly identical to PA morphologically, and PLAG1 expression can be detected by IHC; while some authors (10) have reported PLAG1 gene rearrangements, this has not been the case in all series.
