Core Tip

Core Tip: Bladder metastasis from lung cancer with epidermal growth factor receptor (EGFR) mutation is extremely rare. We reported a case of bladder metastasis from lung adenocarcinoma with EGFR mutation. During routine follow-up of lung cancer patients, imaging examination of the pelvic cavity should be performed to avoid missing bladder metastasis. The ultimate diagnosis of bladder metastasis sill depends on the pathological result of biopsy tissues as determined by cystoscopy. Bladder metastasis with EGFR mutation seems to respond well to the treatment of EGFR tyrosine kinase inhibitors.
