Dermoid Cyst of the Parotid Gland Location.

Dermoid cysts (DCs) can occur anywhere in the body. However, DCs on neck or head are not common, which account for about 7% among all kinds of DCs and mostly occur in superficial areas. These cysts are hardly seen in the parotid gland. It is challenging to make accurate diagnosis before surgery because of its rarity and the ambiguous findings on radiology images. Based on a short review of the literature on DCs in the parotid gland, we discussed their clinical features and histopathological and radiological characteristics.
