Thymic cyst of the neck.
The diagnosis of a thymic cyst of the neck must be considered particularly in a male child with a mass that is lateral, soft, asymptomatic, and closely related to the carotid sheath. Although rare in the literature, this entity is probably more common than usually appreciated. A patient with this condition has been reported along with a review of previous publications on this subject.
