Abstract
A 77-year-old man with smoking history visited Thoracic Surgery department with a complaint of dry cough and dyspnea for months. Chest CT showed a mass over left upper lobe, mediastinal lymph node enlargement and bilateral lung nodules. CT-guide biopsy of the left upper lung mass revealed transitional cell carcinoma. Nevertheless, no primary origin was discovered after a thorough evaluation of genitourinary tract, including abdominal CT, FDGPET, cystoscopy and retrograde pyelography. We will discuss the possible reasons for the unknown primary origin of transitional cell carcinoma in a lung mass.
