[Rheumatoid polyarthritis, Gougerot-Sjögren syndrome and chronic myeloid leukemia. Apropos of 2 cases].

Two cases of rheumatoid arthritis with Sjögren's syndrome are reported which developed chronic myelocytic leukemia. The relationships between these illnesses, rheumatoid arthritis and Sjögren's syndrome on the one hand, and a myeloproliferative disorder on the other hand, are discussed, as well as the possible role of the treatment regimens (synoviorthesis with radio-isotopes in case number 1). The possibility that this association came about by pure coincidence can not be excluded due to the exceptional character of these illnesses.
