Keratocystoma of the Parotid Gland: A Rare Case and Review of the Literature.

Keratocystoma of the parotid gland is a rare benign salivary gland tumor. In 2022, the World Health Organization added keratocystoma to the classification of benign parotid tumors. Recently, our hospital encountered a case involving a 2-year-old child, making this the youngest patient reported to date. We excised part of the parotid gland and lesion under general anesthesia while preserving the facial nerve. There was no local recurrence during the 1-year follow-up period after surgery. Despite its rarity, it is essential to consider the possibility of keratocystoma and distinguish it from other benign neoplastic lesions of the parotid gland.
