Secondary polycythemia (SE) is a clinically rare disease that involves the overproduction of red blood cells. To our knowledge, the association of multiple myeloma and polycythemia has been reported, but the association of SE and multiple myeloma is rare and has been infrequently reported in literature. In contrast to anemia, the presence of polycythemia in multiple myeloma patients is a rare finding. A patient of IgA-λ multiple myeloma with secondary erythrocytosis recently admitted to our department is now reported as follows and relevant literature is reviewed to improve clinicians’ awareness of such rare comorbidities.Keywords: multiple myeloma, secondary erythrocytosis
