Chondroid syringoma of the lower lip: Case report

Chondroid syringoma - also known as mixed tumor of the skin - is a benign skin tumor often occurring in the head and neck region, that usually presents as a slow growing well-defined swelling in adults, with occasional commitment of the lips. The aim of this study was to report an illustrative case of chondroid syringoma in the lower lip of a 43-year-old male patient from Brazil. Physical examination revealed an asymptomatic hardened swelling of normal coloration, measuring 3.0 cm, located at the transition between the skin and semi-mucosa of the lower lip. Under the clinical hypothesis of a salivary gland tumor, an excisional biopsy was performed under local anesthesia. After histopathologic examination the final diagnosis was of chondroid syringoma of the lower lip. There is no evidence of recurrence one year after surgical procedure. Clinicians should consider chondroid syringoma when evaluating well-defined swellings of the lower lip.
