Abstract We report a case of multiple lymphoepithelial cysts of the thyroid gland in a patient with severe chronic lymphocytic thyroiditis. Lymphoepithelial cysts of the thyroid gland are rare lesions that are histologically similar to branchial cleft cysts found in the lateral neck. The cysts have an epithelial lining that is usually stratified squamous epithelium but may be focally respiratory-type epithelium. Abundant lymphoid tissue is present beneath the epithelium, and lymphoid follicles with reactive germinal centers are common features in the walls of the cysts. Because of their similarity to branchial cleft cysts and the presence of intrathyroidal branchiae-derived structures such as thymus and parathyroid gland tissue in the vicinity of some cysts, lymphoepithelial cysts of the thyroid have been postulated to arise from remnants of branchial derivatives; origination from solid cell nest remnants of the ultimobranchial bodies has been raised as a possibility. A definitive origin, however, has not been established. An association with chronic thyroiditis has been noted in 8 of the previously reported 16 cases occurring in a background of Hashimoto or chronic lymphocytic thyroiditis.

<p class="abstract">A branchial cleft cyst is a congenital abnormality typically located over the lateral aspect of neck. A 3 year old boy presented with a gradually progressive painless swelling below his chin since 1 year. CT scan demonstrated well defined cystic lesion in submental region. Excision was done and histopathology showed the cyst lined by stratified squamous epithelium and at places lined by pseudo stratified ciliated columnar epithelium with subepithelial lymphocytes suggesting branchial cyst. Branchial cleft cysts should also be considered as one of the differential diagnoses in cystic midline lesions of the neck, if it’s not moving with deglutition and with tongue protrusion.</p>

A rare case is described of intrathyroidal branchial cleft-like cyst associated with unusual heterotopic tissues including the salivary gland type tissue, fat, and cartilage. This coexistence in the thyroid gland has not been described previously, to our knowledge. The patient was a 7-year-old girl with a growing mass in the left lateral neck. The ultrasonography revealed a cystic lesion in the left thyroid. Histologically, the cyst was lined by squamous or respiratory-type epithelium resting on the fibrous tissue containing lymphoid tissues with follicle formation and solid cell nests (SCNs). This cyst was intimately associated with heterotopic tissues including lobules of well-differentiated seromucinous salivary glands, mature fat tissue, and islands of the cartilage. This association of branchial cleft-like cyst with SCNs and unusual heterotopic tissues in the normal thyroid suggests a possible origin from the SCN as ultimobranchial vestigial structures.
