Renal amyloidosis with nephrotic syndrome in a child suspected of having idiopathic pulmonary hemosiderosis.

A case of renal amyloidosis with nephrotic syndrome in a 12-year-old girl suffering from a chronic pulmonary disease is reported. Data from this patient's history, laboratory examination and radiographic evaluation of the pulmonary lesions favour the diagnosis of a long-standing idiopathic pulmonary hemosiderosis. A possible etiologic relationship between the pulmonary lesions and amyloid deposition in the kidney may be assumed.
