A case of cystic foreign body granuloma in the mantal region caused by inclusion of metal fragments of a sword for 60 years is reported. A 76-year-old man was referred because of a painless swelling in the mental region. Radiological examination suggested a cystic lesion containing foreign bodies. Enucleation of the lesion was performed. The foreign bodies were metal fragments of a sword, found floating in the cystic fluid in the lumen. Histopathologically, the formation of a cyst without an epithelial lining was recognized. The cyst wall was composed of granulation or fibrous connective tissue with hyalinization, many foamy and multinucleated giant cells, and dark brown exogenous pigmentation. The histopathological diagnosis was a foreign body granuloma with cyst formation.
