Chondroid syringoma of the orbit

Abstract

Chondroid syringoma is a rare subcutaneous tumor that mainly affects the face and the neck. The authors present an occurrence in the orbit, which they believe to be the first reported at that site. Computed tomography and magnetic resonance imaging suggested that the tumor had invaded the globe, but at surgery the mass was well circumscribed and did not invade or adhere to other structures. The tumor was resected easily under general anesthesia. Epithelial cells of characteristic appearance within a chondroid matrix were demonstrated histologically. No recurrence has been evident in more than 1 year of follow-up. Most chondroid syringomas are benign, but because several cases have exhibited malignant behavior, periodic observation following complete resection is required.
