ABSTRACT
Describimos un caso de quiste linfoepitelial intratiroideo en un varón de 31 años con tiroiditis linfocítica crónica y diagnosticado previamente de bocio multinodular. La lesión fue extirpada e histológicamente estaba tapizada por epitelio escamoso y/o cilíndrico y subyacentemente presentaba celularidad linfoide con patrón folicular. Según la literatura revisada, tan sólo hay veinte casos descritos en la literatura médica y en diez casos estaban asociados a tiroiditis crónica.We report a case of lymphoepithelial cyst of the thyroid gland in a 31 year-old-man with chronic lymphocytic thyroiditis and history of multinodular goiter. The lesion was resected and the histopathologic examination showed that the cystic mass was lined by squamous and focally columnar epithelium, an it was surrounded by follicular lymphoid tissue. To our knowledge only twenty cases of this lesion have been reported in the medical literature. An association with chronic thyroiditis has been noted in 10 cases.
