Core Tip
Core Tip: This rare case documents thyroid cartilage metastasis from an epidermal growth factor receptor (EGFR)-mutated lung adenocarcinoma (p.E746_S752delinsV) in a 51-year-old smoker. Despite the avascular nature of cartilaginous tissue, the patient presented with neck masses, weight loss, and widespread metastases (pT3N3M1c, stage IVB). First-line gefitinib achieved remarkable regression of cervical, abdominal subcutaneous, and oropharyngeal lesions at 6 months. Key highlights: (1) Thyroid cartilage metastasis, though exceptionally rare, warrants vigilance in lung cancer; (2) EGFR targeting remains effective even in unusual metastatic patterns; and (3) Multidisciplinary management optimizes outcomes. Early molecular testing is critical for tailored therapy.
