Synopsis

The oral lymphoepithelial cyst arises from proliferation of epithelium within lymphoid or tonsillar tissue. Some believe this epithelium represents enclaved or "trapped" epithelium while others believe it is of salivary gland origin. It generally occurs in the fourth decade of life with an equal sex predilection. The patient may feel a painless lump or swelling that is slow-growing.
