Benign cervical cystic teratoma.
Teratomas of the neck are rare in adults. Nine adult patients have been previously reported on in the world literature; six had malignant and three had benign lesions. Most of the lesions were seen as a mass in the neck, but teratoma is rarely considered in the differential diagnosis of neck lesions. A tenth patient, whose case we are presenting, had a supraclavicular sinus mass that was diagnosed at surgical exploration. The tumor was successfully resected and proved to be benign.
