甲状舌管遺残組織から発生する癌は稀である.甲状舌管嚢胞の診断にて摘出術を行い,病理組織的検索で甲状舌管遺残組織に発生した異所性甲状腺癌と診断された症例を経験した.<br> 症例は37歳女性.1991年9月頃,前頸部に腫瘤を触知,次第に増大するため1992年3月当科を受診した.超音波,CT検査にて舌骨に接して径3cmの腫瘤を認めた.正常甲状腺とは離れた部位に存在し,頸部リンパ節腫脹を認めなかった.穿刺吸引細胞では確診が得られなかった.甲状舌管嚢胞の診断にて腫瘤摘出術を施行した.腫瘍割面は嚢胞状で,嚢胞壁の内部を充満するように乳頭状の隆起性病変を認めた.病理組織学的には嚢胞壁の乳頭状部に乳頭癌組織が認められ,周囲に正常甲状腺組織も認められた.甲状舌管嚢胞の治療にあたっては異所性甲状腺癌の発生を考慮し,充分な検索と治療が必要と考えられた.

Carcinomas arising in the thyroglossal duct are comparatively rare. We experienced a case of ectopic thyroid carcinoma arising in the remnant thyroglossal duct which was histologically determined after resection of a mass diagnosed with cyst of the thyroglossal duct.<br> A 37-year-old woman was seen at the hospital because of a gradually enlarging mass at the anterior region of the neck which was first felt about 6 months before. Ultrasonography and CT revealed a mass 3cm in diameter in contact with the hyoid bone. The border between the mass and normal thyroid was clear and no enlarged lymph nodes were observed. Any delinite diagnosis was not obtained based on aspiration biopsy. Under a diagnosis of cyst of the thyroglossal duct, the mass was removed. The section of the mass had cysts and there was a papillary elevated lesion in the inside of the smooth cystic wall. Pathologically, tissue of papillary carcinoma was observed in a part of the cystic wal and there was also the normal thyroid tissue in contact with its site. In the treatment of thyroglossal duct cyst, sufficient search and examination as well as treatment are considered to be necessary by entertaining a possible occurrence of ectopic carcininoma of the thyroid.
