A Case of Newly Diagnosed Chronic Myelomonocytic Leukemia with Rheumatoid Arthritis Presentation

Abstract

Gabriel McCoy and William Edenfield

We describe a case of newly diagnosed chronic myelomonocytic leukemia that presented with predominantly rheumatologic symptoms. In addition to the deletion of chromosome 12p, marrow cytogenetics also revealed a unique translocation, t(x:4). This finding was not a constitutive abnormality. We report this unusual chromosomal abnormality and hypothesize about the potential immunogenicity of the gene product and its relation to the patient’s rheumatologic complaints.
