Midline ectopic thyroid tissue is a common pathological entity. In contrast, laterally located ectopic thyroid tissue with a normally located thyroid gland is a very rare condition in head and neck surgery.
We report the association of laterally located multinodular thyroid tissue and a normally located multinodular goiter. A woman was seen in the otolaryngology clinic with a right submandibular mass. Clinical examination and investigations confirmed the presence of a multinodular goiter in an ectopic thyroid gland.
Laterally located ectopic thyroid tissue is a very rare condition. Ectopic thyroid tissues can undergo the same pathological changes as a normally located thyroid gland. Ectopic thyroid goiter together with a normally located multinodular goiter is a rare entity, and this is the first to be reported in North America.
中线异位甲状腺组织是一种常见的病理实体。相比之下，具有正常位置甲状腺的侧方异位甲状腺组织是头颈部外科中非常罕见的情况。
我们报告了侧方多结节性甲状腺组织与正常位置多结节性甲状腺肿的关联。一名女性因右下颌下肿块到耳鼻喉科就诊。临床检查和检查证实存在异位甲状腺中的多结节性甲状腺肿。
侧方异位甲状腺组织是一种非常罕见的情况。异位甲状腺组织可能会经历与正常位置甲状腺相同的病理变化。异位甲状腺肿与正常位置的多结节性甲状腺肿一起是一种罕见的实体，这是在北美首次报道。
