Successful treatment with low-dose weekly methotrexate in a case of undifferentiated spondyloarthropathy coexisting with cutaneous polyarteritis nodosa.

摘要

A case of a 56-year-old woman diagnosed with HLA-B27-positive undifferentiated spondyloarthropathy who developed cutaneous lesions consistent with cutaneous polyarteritis nodosa is presented. The rarity of this association and the dramatic response of both conditions to low-dose weekly methotrexate are emphasised.
