An unusual presentation of papillary thyroid carcinoma in a pediatric patient: A case report

Cystic neck masses in the pediatric population are common but rarely concerning for malignancy. Given this typically benign nature, they are frequently managed conservatively. Here we present an unusual case of a waxing and waning cystic neck mass in a pediatric patient. After surgical removal, the mass was found to be metastatic papillary thyroid cancer. This is a unique presentation in the pediatric age group that has not yet been described. Based on this case, we suggest an expanded differential in any workup for a cystic neck mass to include papillary thyroid carcinoma, regardless of the patient's age.
