RESUMEN
A young lady presented to us with clinical and biochemical evidence of Nephrotic Syndrome. Her laboratory investigations also revealed Erythrocytosis, Leucocytosis and Thrombocytosis. A renal biopsy revealed a diagnosis of Amyloidosis which was further characterized as AL amyloidosis with further investigations (kappa chain monoclonal gammopathy). She was started with appropriate therapy and she showed significant decline in her monoclonal Proteins on follow up. Her Erythrocytosis, Leucocytosis and Thrombocytosis also normalized with the decline in the levels of monoclonal light chains. We postulate a link between the monoclonal protein associated growth factors and inflammatory markers which were responsible for this unique association between AL Amyloidosis and tri-lineage hematopoietic cell proliferation.
