Systemic lupus erythematosus (SLE) and ankylosing spondylitis (AS) are two distinct immunological disorders with different etiopathogenic profiles and their co-existence is very rare. The present study discusses two cases of co-existing AS with SLE. The first case, which fulfilled the criteria for lupus, had HLA-B27 arthritis with predominant peripheral involvement, bilateral hip disease associated with non-scarring alopecia, recurrent oral ulcers and positive immunological markers. The second case was of a 37-year-old male with lupus (predominantly musculoskeletal and cutaneous) who presented with inflammatory low backache. The patient had high titers of ANA and anti-dsDNA positivity and was on methotrexate treatment. On evaluation, he was found to have HLA B27 positivity and bilateral active sacroiliitis. The distinguishing feature of both the cases was that the time frame of presentation of the disorders was almost same, while second case had a significant time frame between the two disorders.
