Nephrotic syndrome and juvenile dermatomyositis

Juvenile dermatomyositis (JDM) is a rare autoimmune disease characterized by proximal muscle weakness, skin lesions, gastro intestinal, pulmonary, cardiac and small nerve damage. Renal involvement has been rarely reported in JDM. This is the report of a 7-year-old boy presented with nephrotic syndrome (NS) and subsequent renal failure. Clinical manifestations of JDM appeared gradually. Renal manifestations could be considered as a rare initial presentation of JDM.
