Chronic inflammatory rheumatism associated with Takayasu disease.

Takayasu disease is rarely associated with other autoimmune diseases. Therefore, the cases discussued herein are uncommon because we are reporting Takayasu disease associated with rheumatoid polyarthritis and spondylarthropathy. The first case concerns a 40-year-old woman presenting with Takayasu disease 11 years after the diagnosis of erosive and seronegative rheumatoid polyarthritis. The upper limb arteries and 1 lower limb artery were affected. The second 41-year-old case presented with ankylosing spondylitis that had been evolving for 10 years. Human leukocyte antigen-B27 typing was negative. Takayasu disease was revealed by severe high blood pressure. In both cases, radiologic examination revealed a typical aspect of the aorta and its main collaterals. Rarely in the literature have these associations been reported, and the pathology remains unknown.
