Thyroglossal duct cyst is the most common upper neck midline lesion in children. Approximately 1% of
thyroglossal duct cyst undergoes malignant transformation. Calcification which is a marker of malignancy
almost always points out to papillary thyroid carcinoma. Benign case of calcified thyroglossal cyst maybe
undiagnosed or under reported. We report a case of a 5 year old girl with a benign calcified thyroglossal
duct cyst, a fourth case in world literature. Here the differences between a benign and malignant
thyroglossal duct cyst are discussed.
