[Rheumatism caused by lipid thesaurismosis. Articular involvement in hyperlipoproteinemia type II : presence of microcrystals in the mitochondria of synoviocytes].

For 13 years polyarthritis with specific synovial involvement was observed in a case of type II hyperlipoproteinemia. Microcrystals similar to those described in Gaucher's and Fabry's disease were seen in synovial cytoplasm and mitochondria. These data suggest a microcrystalline pathogenesis for type II hyperlipoproteinemia arthritis as in gout and chondrocalcinosis.
