To review the diagnosis of primary papillary carcinoma of ectopic thyroid tissue within branchial cleft cysts, and to discuss the diagnostic challenge of differentiating this condition from metastatic disease when an occult microcarcinoma is found in the thyroid gland.
These comprise a case report and a literature review. We present the case of a 75-year-old woman with papillary thyroid carcinoma within the wall of a recurrent, 15 cm, lateral neck cyst.
Histological examination of the patient's thyroid gland found a 0.5 mm papillary thyroid microcarcinoma.
Our differential diagnosis was primary papillary carcinoma arising from ectopic thyroid tissue, or metastatic cystic degeneration of a lateral lymph node. We make an argument for the former.
回顾鳃裂囊肿内异位甲状腺组织原发性乳头状癌的诊断，并探讨当甲状腺内发现隐匿性微小癌时，将这种情况与转移性疾病相鉴别的诊断挑战。
包括病例报告和文献综述。我们报告了一名75岁女性的病例，其复发性15厘米侧颈囊肿壁内有甲状腺乳头状癌。
对患者甲状腺进行组织学检查发现一个0.5毫米的甲状腺乳头状微小癌。
我们的鉴别诊断是异位甲状腺组织起源的原发性乳头状癌，或侧方淋巴结转移性囊性变。我们支持前者。
