SAN MIGUEL FRAILE, P. et al. Lymphoepithelial cyst of the thyroid gland: a case report and review of the literature. An. Med. Interna (Madrid) [online]. 2006, vol.23, n.5, pp.232-234. ISSN 0212-7199.

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.
