Report on a HL-A B27 positive female patient with the typical cardiac lesion occasionally found inankylosing spondylitis, peripheral arthritis, and acute anterior uveitis but without clinical or radiological evidence of spine or sacroiliac joint involvement. The concept of "HL-A B27 associated disease", including ankylosing spondylitis as well as Reiter's disease or other forms of seronegative rheumatic diseases, is suggested.
