The occurrence of lymphadenopathies was investigated in 23 patients with diverse rheumatic conditions who had silastic prosthesis in joints of the hands, to determine whether these adenopathies were due to the presence of silicone particles. Five cases had clinically detectable lymph node enlargement and tissue samples were studied by light and scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDXA). In 3 out of the 5 cases foreign body granulomas were observed by light microscopy, SEM showing a highly irregular distribution of foreign body material with a peak for silicone by EDXA. Foreign body particle distribution closely correlated with silicone concentration. No granulomas were found in the two remaining patients with adenopathies who presented a non-specific reactive lymphadenitis. Our findings show that silicone lymphadenopathy is a more frequent complication (13%) of silastic arthroplasty than is usually recognized and therefore should be considered in the differential diagnosis of patients with lymph node enlargement who have previously received a silicone arthroplasty. |
