Monoclonal gammopathy associated with multiple myeloma and visceral leishmaniasis in the dog: a comparison of two cases.
The term monoclonal gammopathy (MG) suggests the presence of clonal immunoglobulins in blood serum that are recognized as narrow spikes in the beta and/or gamma region of the electrophoretic pattern of serum. In the dog, MG is rare and is associated with a heterogeneous group of diseases that include multiple myeloma (the most common source of MG) as well as infectious and chronic inflammatory diseases such as Leishmaniasis. In this paper, two cases of MG are described: the first case is associated with multiple myeloma of monoclonal component type IgA/lambda, with the latter rare in dogs, and the second case involves MG that developed 3 years after an initial diagnosis of Leishmaniasis.
