Thyroid cancer is the most common endocrine cancer, accounting for about 1% of all cancers. Sarcomas, lymphomas and metastases to the thyroid gland are rare and only with a handful of descriptions in the literature.
To describe rare histological types of thyroid cancer found in a reference center.
Medical chart review from admitted patients diagnosed with thyroid cancer in the period from 1977 to 2010. Demographic, diagnostic, therapeutic and histopathological information were collected.
3,018 records of patients admitted with thyroid disease were reviewed. Among the cases diagnosed with rare tumors there was a predominance of: anaplastic carcinoma: 22 cases (0.7%), followed by 11 cases of medullary carcinoma (0.36%); 2 cases of sarcoma (0.07%), 2 cases of lymphoma (0.07%) and one case of metastatic carcinoid tumor (0.03%). There were more females diagnosed (57%) as well as Caucasians (84%). The most frequent clinical presentation was a palpable thyroid nodule. All patients with lymphoma, sarcoma and anaplastic carcinoma died.
Sarcomas, lymphomas and thyroid metastases are uncommon and tend to worse outcomes.
甲状腺癌是最常见的内分泌癌，约占所有癌症的 1%。肉瘤、淋巴瘤和甲状腺转移瘤很少见，文献中只有少数描述。
描述在参考中心发现的罕见组织学类型的甲状腺癌。
对 1977 年至 2010 年期间在我院确诊为甲状腺癌的住院患者的病历进行回顾性分析。收集人口统计学、诊断、治疗和组织病理学信息。
共回顾了 3018 例患有甲状腺疾病的患者记录。在诊断为罕见肿瘤的病例中，以未分化癌为主：22 例（0.7%），其次是 11 例髓样癌（0.36%）；2 例肉瘤（0.07%），2 例淋巴瘤（0.07%）和 1 例转移性类癌瘤（0.03%）。诊断为女性（57%）和白种人（84%）的患者更多。最常见的临床表现是可触及的甲状腺结节。所有患有淋巴瘤、肉瘤和未分化癌的患者均死亡。
肉瘤、淋巴瘤和甲状腺转移瘤并不常见，且预后较差。
