Abstract
A case of chronic myelomonocytic leukemia (CMML) associated with primary amyloidosis (AL) is presented. Hepatosplenomegaly, macroglossia, and xanthelasma were the major physical findings. Laboratory tests showed macrocytic anemia, thrombocytopenia, monocytosis and a bi-clonal gammopathy. Early monocytes and monoblasts were noted in the bone marrow aspiration biopsy. Cytogenetic evaluation showed a clonal deletion of chromosome 21 long arm (21q-). Amyloid was present in the liver, tongue and xanthelasma. In addition, the patient was noted to have osteosclerosis of the lower extremities. Treatment with prednisone and colchicine resulted in a subjective response. The unusual association of CMML, and primary amyloidosis is discussed.
