A 39-year-old man underwent a right upper lobectomy and lymph node dissection for right lung adenocarcinoma on March 7, 1988. He was referred for an evaluation of a systemic bone scintillation scan on October 29, 1996. A hot spot at the right fourth rib was recognized. After performing needle aspiration cytology, a diagnosis of adenocarcinoma was made. This case was considered to be rib metastasis occurring 8 years after surgery for lung cancer. In general, regular follow-up examinations are performed for at least 5 years after surgery; however, surgeons should also keep such late metastatic cases in mind.
