title: Unusual presentation of multiple myeloma. A report of 2 cases.
abstract: The diagnosis of multiple myeloma (overt plasma cell dyscrasia) is usually not considered in patients under 30 years of age. Furthermore, multiple myeloma with coexistent megaloblastic and iron deficiency anaemia is very uncommon. Within 6 months we encountered 2 patients under 30 years of age who had multiple myeloma, one with advanced secondary amyloidosis and the other with severe megaloblastic and iron deficiency anaemia.
