An unusual chondroid syringoma.

A case report of a clinically malignant mass measuring 10 x 8 x 10 cm over the shoulder of a 55-year male patient is presented. In the ultrasound examination, it was indicated that the soft tissue tumor did not invade the chest wall. The excisional biopsy revealed a benign chondroid syringoma. This is a report of a quite rare chondroid syringoma case and its clinical presentation, localization, and diameter.
