A 56-year-old male was admitted to National Tohsei Hospital on November 14, 1989, complaining of lower abdominal pain and a mass. An ultrasonogram, a barium enema and rentogenography, a colonofiberscopic examination and an abdominal CT revealed a hard hen's egg sized tumor of the appendix. The tumor was diagnosed preoperatively and operated on as a primary cancer of the appendix, but the resected specimen was found to be a chronic inflammatory granuloma of the appendix due to fish bone perforation. This believed to be the first report of such a case in Japan.
