[Lower limb lymphedema: A rare manifestation of spondyloarthropathy].

INTRODUCTION

Spondyloarthritis include articular (axial, peripheral or enthesitic) and extra-articular manifestations. We reported three cases of limb lymphedema associated with a spondyloarthritis.

CASE REPORTS: We report on two men and one female aged of 75, 52 and 39 years, respectively. The rheumatic disease was an ankylosing spondylitis HLA B27 positive in two patients and a psoriatic arthritis in the remaining one. Lymphedema, always unilateral, confirmed by the Stemmer's sign, involved the whole lower limb (n=2) or only the foot and calf (n=1). Lymphedema occurred 3 months, 40 and 9 years after the onset of spondyloarthritis. Lower limb lymphoscintigraphy was abnormal in all cases: decrease (n=2) or absence (n=1) of inguinal lymph node uptake, and visualization of the popliteal lymph node related to deep lymphatic pathway (n=1). Treatment of the spondyloarthritis did not improve lymphedema. Both the low-stretch bandage and elastic compression treatment allowed its reduction and stabilization.

CONCLUSION

Limb lymphedema is a rare extra-articular manifestation of spondyloarthritis. Its course appears to be independent of joint disease. Its management is specific and should be associated to that of the rheumatologic disorder.
