A cutaneous or systemic vasculitis occurs in
myelodysplasia
as well as in myeloproliferative and lymphoproliferative disorders. The most common lesion is a leucocytoclastic vasculitis, with neurological or joint involvement occurring less often. The vasculitis may appear contemporaneously with or precede the clinical onset of the blood dyscrasia. Occasionally the lesions respond dramatically to the use of steroids but in general, patients with vasculitis have a worse prognosis than those with uncomplicated
myelodysplasia
. Vasculitis and
myelodysplasia
appear together too often for the association to be coincidental and the vasculitis in most cases cannot be attributed to intercurrent infections, therapeutic agents or a pre-existing rheumatological disorder. While autoantibodies are frequently present in
myelodysplasia
, and
ANA
and anti-neutrophil cytoplasm antibodies (ANCA) are found in other vasculitides, neither of these antibodies is associated with the vasculitis of
myelodysplasia
. There has however been one report of ANCA in Sweet's syndrome a non-vasculitic skin condition that also occurs in the
myelodysplastic syndromes
.

Several reports have documented various forms of glomerular diseases in adults with
myelodysplastic syndromes
(
MDS
), but similar reports in children are lacking. We describe two children with
MDS
-associated steroid-responsive nephrotic syndrome (NS). Patient 1, who had
MDS
with myelofibrosis, presented with hepatosplenomegaly, pancytopenia, chronic hepatitis, moderate proteinuria, hypocomplementemia and elevated
ANA
titer. During initial prednisone treatment proteinuria markedly diminished and partial but transient hematological improvement occurred. Relapse subsequently occurred that manifested by overt NS and pancytopenia. High doses of prednisolone led to remission of the renal disease, but hematological remission did not occur. Persisting pancytopenia and repeated infections terminated in sepsis, 2 years after the onset of the
MDS
. Patient 2, who had refractory anemia with clonal monosomy 19, presented with bowel disease, hepatosplenomegaly, anemia and non-organ-specific autoantibodies. Prednisone led to both clinical and hematological remission. The hematologic disease relapsed 12 months later, when nephrotic-range proteinuria, hematuria and mild azotemia were also found. Corticosteroid treatment led to long-lasting renal and hematologic remission, maintained by a small dosage of prednisone. In both patients, renal biopsy findings were consistent with those seen in idiopathic NS. A Medline search disclosed 16 cases of glomerulopathy in the course of
MDS
in adult patients. Clinical features included NS, usually accompanied by renal insufficiency with acute, chronic, or rapidly progressive glomerulonephritis. On biopsy, membranous nephropathy, crescentic or mesangial proliferative glomerulonephritis, and AL amyloidosis were found. We conclude: (1) that glomerular disease may be present and should be searched for in patients with
MDS
and (2) that
MDS
can be added to the list of rare conditions associated with corticosteroid-responsive NS in children.

Relapsing polychondritis (RP) is a rare rheumatologic disorder in which recurrent episodes of inflammation result in destruction of cartilage of the ears and nose. The joints, eyes, audio-vestibular system, heart valves, respiratory tract, kidneys, and skin can also be involved. Skin involvement is most frequently linked to concomitant
myelodysplastic syndrome
and has rarely been associated with systemic lupus erythematosus. A 47-year-old woman presented with violaceous, indurated, tender plaques on the bilateral cartilaginous ears with sparing of the lobes, consistent with RP. Further investigations revealed positive
ANA
and anti-Smith antibody, oral ulcers, a photo-distributed skin eruption, and biopsy-proven lupus nephritis, leading to a second concomitant diagnosis of systemic lupus erythematosus (SLE). The diagnosis of SLE associated with RP was made and the patient was started on oral prednisone and hydroxychloroquine. This is a rare report of SLE associated with RP. It is unclear whether RP occurring in patients with SLE represents another clinical manifestation of SLE or a coexisting disease. However, a significant
ANA
titer in a patient with RP strongly suggests the presence of an associated autoimmune disorder. If immunologic abnormalities usually found in SLE are detected in patients with RP, it is important to monitor patients for the development of other manifestations of SLE.
