Abstract
Cases of multiple cancer have increasingly been reported in recent years. We report here a rare case of quintuple cancer including multiple primary oral cancer.
The patient was a 60-year-old male who was introduced by a nearby dental clinical with a chief complaint of pain in the left oral floor. He had a previous history of lung cancer and laryngeal cancer. Tumor resection was performed to remove squamous cell carcinoma in the left oral floor.
Two years after our operation he developed colon cancer and esophageal cancer and was operated on for each. Thereafter, he developed left tongue cancer, a year later right tongue cancer, and three years later right buccal mucosa cancer, and respective operations were performed. The patient had a good clinical course after treatment. All treatments for this case were provided by our hospital. It is considered to be a benefit of general hospitals that good and close cooperation among clinical departments was possible in this case.
