Unilateral cervical thymic cyst in a child: A rare case report

The histological features were diagnostic. Addtionally, a small focus of ectopic parathyroid tissue in the wall of the cyst was present which has been rarely reported in literature. Thymic cyst can be diagnosed only by histopathology and the knowledge of this entity will prevent its misdiagnosis
