Gingival cysts are, as their name implies, located in the gingival tissues. They probably arise from the rests of Serres. They may exhibit keratinization. Plaques similar to those occurring in the lateral periodontal cyst may also be seen.
Therefore, the gingival cyst may be considered the soft tissue counterpart of the lateral periodontal cyst.
Gingival cysts of infants occur either single or multiple in the jaw mucosa of the newborn infant. When occurring at the midline of the palate, they are known as palatal cysts of infants. Histologically, they resemble epidermoid cysts and do not contain the epithelial plaques diagnostic of the adult-type gingival cyst mentioned above.
