Chain Saw Blade Granuloma: Reaction to a Deeply Embedded Metal Fragment

Arch Dermatol. 2006;142(8):1065-1086. doi:10.1001/archderm.142.8.1079

We report a case of foreign body granuloma caused by a metal fragment from a chain saw. Since our patient had no history of injury and since several incisional biopsy specimens showed no foreign body, we had difficulty arriving at the diagnosis. Finally, pantomography revealed a small piece of metal and x-ray microanalysis of this piece was consistent with the edge of a chain saw. To our knowledge, this is the first case reported of foreign body granuloma caused by a chain saw blade fragment.
