Chondroid syringoma: a rare tumor of the chest wall.

Chondroid syringoma, an uncommon, slow-growing, benign, sweat-gland tumor located on the upper right chest wall of a 66-year-old woman is presented. This skin adenexal tumor is typically located on the head and neck region. The unusual location of chondroid syringoma made an accurate preoperative diagnosis difficult, and diagnosis was achieved only by excisional biopsy and histopathologic examination. Total surgical excision remains the best therapeutic option to avoid tumor recurrence and close follow-up is recommended because of a rare possibility of malignant transformation and visceral metastases. 2010 The Society of Thoracic Surgeons.
