A case of primary lung cancer was detected owing to a high level of CA19-9. An 80-year-old male who had experienced sigmoidectomy for colon cancer 10 years previously exhibited a high-level of serum CA19-9 upon outpatient examination. Abdominal examination showed no abnormal findings. Chest CT revealed a bulla with a thickened wall in the left S6. Histological examination of a lung specimen obtained by TBLB showed adenocarcinoma. We performed a left lower lobectomy. Histological examination of a lung specimen obtained at operation revealed a well-differentiated papillary-type adenocarcinoma. Immunohistochemically, the tumor cells stained positively for CA19-9. We ultimately diagnosed a primary lung cancer producing CA19-9.
