NECROBIOTIC PALISADING SUTURE GRANULOMAS INVOLVING BONE AND JOINT - REPORT OF 2 CASES

Biomaterial used in surgery is relatively inert and non-toxic; however , adverse reactions may follow implantation of such foreign material. We describe the first two cases of bone and joint destruction by necro biotic palisading suture granulomas. The hypersensitivity reaction occ urred years after shoulder repair using silk sutures. One patient rece ived chemotherapy for a mistaken diagnosis of tuberculous arthritis. A lthough very rare, foreign material should be included in the differen tial diagnosis of necrotizing granulomas. A history of surgery and mic roscopic examination with polarized light should allow recognition of this entity.
