Chondroid Syringoma of the Medial Canthus

Chondroid syringoma, or pleomorphic adenoma of the skin, is a rare, benign skin adnexal tumor. It is usually exhibited as a slowly growing intradermal or subcutaneous nodule, typically located in the head and neck region. Because of the unremarkable clinical symptomatology of this rare tumor, the diagnosis is exclusively made retrospectively based on histological confirmation of the surgically excised tumor. We present a rare case of a chondroid syringoma located in the left medial canthus of a 58-year-old man. The patient had no symptoms and decided to excise it for cosmetic reasons only. Local excision with a macroscopic wide cuff of normal tissue was done, without destroying the aesthetic and functional structures, since the defect was restored by a finger flap. One year postoperatively, the patient has remained disease-free. Chondroid syringoma usually appears in the face but the location in the medial canthus is not mentioned in the literature for the last twenty years. 1. Introduction The chondroid syringoma, or mixed tumor of the skin, is a benign neoplasm of sweat gland origin and a rare clinical entity. Histologically, it could be described as a neoplasm consisting of epithelial and myoepithelial cell formations within a myxomatous, pseudochondromatous, or hyaline stroma that contains mucous secretions [1]. It is usually located in the skin of the face and the scalp in patients between the age of 20 and 60 years with a distinct male predominance [2]. The most common sites are the nose, cheek, upper lip, scalp, forehead, and chin [3]. Chondroid syringoma appears clinically as a slowly growing, painless or subcutaneous nodule. Lesions are firm and adherent to overlying skin but distinct from underlying structures. We report a very rare case of chondroid syringoma located in the left medial canthus. This location has not been mentioned in the literature for the last twenty years. 2. Case Report A 53-year-old male patient consulted our oral and maxillofacial surgery outpatient clinic for an asymptomatic exophytic lesion in the left medial canthus. The patient requested surgery for cosmetic reasons. According to the patient the lesion had first appeared six months before the clinical examination and it was growing very slowly. He did not complain of any symptoms except for the cosmetic problems. On examination the lesion diameter was 1？cm and located in his left medial canthus, without limiting his sight (Figure 1).
