Longstanding isolated bilateral Achilles tendinitis

The case of a patient with a 15-year history of isolated HLA-B27-associated bilateral Achilles tendinitis without other features of seronegative spondyloarthropathies is reported. This case suggests that Achilles tendinitis may be, for a long time, the only clinical manifestation of an HLA-B27-associated disease process. The theory of a separate B27-associated disease entity cannot be excluded yet.
