Lymphoepithelial Cyst in Jugal Mucosa

mouth lymphoepithelial cyst is rare, with few cases reported in literature. the aim of this article is to describe a clinical case, focusing on clinical and diagnostic aspects, treatment and prognosis. the lesion was one year old and had developed as a fibrous nodule in the jugal mucosa of a 71-year-old leucoderma patient. considering focal inflammatory fibrous hyperplasia, fibroma and mucocele as differential diagnosis, excisional biopsy was carried out. a cystic cavity limited by pseudostratified epithelium without projections into the conjunctive tissue, with lymphoid tissue within, was microscopically identified. without postoperative adverse events, the one-year clinical followup confirmed the favorable prognosis of this kind of lesion.
