Introduction:
Spondyloarthritis (SpA) is a chronic inflammatory rheumatism most commonly affecting young men. It is characterized by pelvic-spinal involvement which may be isolated or associated with peripheral joint and/or enthesitic involvement and by association with the human leukocyte antigen B27 (HLA-B27) haplotype (1).
Among the extra-articular manifestations of SpA, renal involvement is rare and mostly severe . AA amyloidosis, IgA nephropathy and urolithiasis are the most common causes. However, other nephropathies could be seen in SpA; they are rare and limited to case reports (2,3). Thus, we report the case of a focal segmental glomerulosclerosis and hyalinosis (FSGS) in a patient with axial SpA.
