Median cervical cyst is characterized by a hemispheric, flat, smooth, and soft tumor and usually is located in the center of the anterior neck. The diagnosis of median cervical cyst is easy in adult patients, but not in children. We treated nine children with a median cervical cyst who visited our department between January 1989 and September 2003. Among these patients, three children underwent surgery and none had recurrence. Paracentesis or incision is sometimes performed for the treatment of the cyst. However, since the cyst recurs easily with these procedurs, total excision by surgery is recommended.
