He was diagnosed with bladder transitional cell carcinoma (grade III) 8 months ago, and he underwent radical cystectomy after receiving local radiotherapy. Transthoracic needle aspiration was diagnosed as metastatic transitional cell carcinoma. The authors report that lung metastatic holes are rare. Of the 398 metastatic patients, only 16 had cavitation lesions. More than two thirds of lung metastatic holes originate in squamous cell carcinomas of the larynx esophagus or cervix, and 1/3 may be adenocarcinomas, and most come from colon or rectal cancer.
