Fine needle aspiration cytology of chondroid syringoma.

Chondroid syringoma (CS) is a rare, benign, appendageal tumor with diagnostic feature of myxochondroid stroma supporting eccrine and apocrine epithelial structures. The usual presentation is a painless, slowly growing mass, typically located in the head and neck region. It usually affects middle-aged and older male patients. Because of its unremarkable clinical presentation it is often overlooked. It should be included in the differential diagnosis of cutaneous head and neck tumors, especially in middle-aged men. Optimal treatment of CS is total surgical excision. We present a 63 year-old man with a small nodule on the neck with 5 years of duration. The diagnosis was made initially on fine needle aspiration cytology that was performed by ultrasound guidance and confirmed subsequently by histology. FNA cytology may be very useful to determine diagnosis before excision.
