Thyroglossal duct cyst: an infrequently considered diagnosis in pediatric patients with anterior neck masses.

Objective: To describe a pediatric patient with an anterior neck mass and discuss the evaluation and treatment.

Methods: We present a case report and a discussion of the differential diagnosis of anterior cervical masses. The workup and therapy for an anterior neck mass, which was a thyroglossal duct cyst, are reviewed.

Results: A thyroglossal duct cyst in pediatric patients is an uncommon finding. For establishing a correct diagnosis, surgical confirmation is necessary. Identification is important because of the high incidence of misdiagnosis, recurrent infections, inadequate treatment, and possible neoplastic change.

Conclusion: A thyroglossal duct cyst should be included in the differential diagnosis of an anterior neck mass. Recommended treatment consists of surgical removal of the cyst, the entire thyroglossal duct tract, and the central portion of the hyoid bone.
