Cisto linfoepitelial em língua: relato de caso em localização incomum

ABSTRACT Oral lymphoepithelial cyst (OLEC) is an uncommon lesion that develops in oral lymphoid tissue. The aim of the present study was to report a clinical case of OLEC in the tongue. A 22-year-old patient presented a nodular lesion, yellowish, with a softened consistency, measuring 0.5 cm in the ventral surface of the tongue. Under the clinical hypotheses of mucocele and OLEC, excisional biopsy was performed. The histopathological examination revealed a cystic lesion covered by a parakeratinized stratified squamous epithelium, which presented in its fibrous capsule a prominent lymphoid tissue. Based on the definitive diagnosis, surgical excision of the lesion was performed.
