Objective: To explore the clinical characteristics of case of thyroid adenoma in the piriform fossa, and review the literatures of the congentital thyroid gland abnormality. Methods: A 44-year-old male had foreign body feeling in his pharynx for 3 years. A mass in his left piriform fossa was detected by the clinical and imaging examination. Biopsy report that the mass was thyroid papillary carcinoma. The resection of tumor with partial back thyroid cartilage through lateral neck and pharyngeal approach was performed. Results: The surgical wound healed in first-stage and no any surgical complication occurred. With postoperative pathological and immunohistochemical examination, the mass was finally diagnosed as thyroid gland adenoma. Staining for cytokerantin19 was negative. Conclusion: The symptomatic and neoplastic abnormal thyroid gland should be excised, but asymptomtic, non-neoplastic and functional abnormal thyroid gland should be retained with regular follow up.
目的： 探讨一例梨状窝甲状腺腺瘤患者的临床特点，并对先天性甲状腺异常作文献综述。 方法： 经临床和影像检查发现1例左侧梨状窝肿物，其正常部位同侧甲状腺正常，右侧甲状腺良性结节，梨状窝肿物活检病理报告为"甲状腺癌" ，采用颈侧及咽侧切开手术，切除左侧部分甲状软骨板后部，完整切除肿瘤。 结果： 手术切口一期愈合，未发生任何并发症，肿瘤病理确诊为甲状腺腺瘤，否定了活检病理诊断；术后1年随访肿瘤无复发，正常部位甲状腺无新病变，甲状腺功能正常。 结论： 有症状及肿瘤表现的异常甲状腺应行手术切除，先天性甲状腺异常命名应规范，无症状、非肿瘤、有功能者可保留并随访观察；功能低下者可替代治疗。.
