[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.
