Abstract
We describe a 52-year-old patient with longstanding rheumatoid arthritis (RA) who developed an acute polyarthritis of her hands and wrists. Synovial fluid analysis revealed the presence of intra and extracellular lipid microspherules with the typical appearance of Maltese crosses under polarized light microscopy. No other specific cause could be identified. This is the first description of an acute polyarthritis associated with lipid microspherules in RA.
