A 94-year-old man had noticed a swelling on his chest since July 1998. The size of the swelling had increased quickly from February 1999. He had experienced bleeding from the swelling frequently, he had falt difficulty in daily life. He consulted his doctor. His doctor suspected his swelling as a malignant tumor and presented us on July 7, 1999. We excised his swelling completely and examined it by histopathology under an optical and an electron microscope. We diagnosed this case as “Merkel cell carcinoma”. There were no findings of metastasis detected by his whole body. This case is the first report of merkel cell carcinoma developed on the chest of a great aged man.
