胸骨前甲状腺乳头状癌：气管前筋膜的悖论

推荐 为探究甲状腺乳头状癌（PTC）胸骨前延伸的罕见现象，研究人员针对一例64岁男性患者开展研究。结果显示，肿瘤可能通过侵犯气管前筋膜和带状肌导致胸骨前扩展，根治性手术为有效治疗手段，该发现为理解PTC的侵袭机制提供了新视角。

Presternal extension of papillary carcinoma thyroid is extremely rare and inexplicable. Infiltration of pretracheal fascia and strap muscle may be the possible explanations for the presternal extension in malignant thyroid lesions. Here, a rare case of presternal papillary thyroid carcinoma in a 64-year-old male patient is reported, which was treated with radical surgery.
