Pericardial effusions in dogs are most often diagnosed as haemorrhagic and idiopathic. Pericardial effusions secondary to an underlying neoplastic process are infrequently diagnosed, as neoplastic cells are rarely observed in a sample of the effusion. In the present report, we describe a 9-year-old dog with pericardial effusion due to T-cell lymphoma of granular lymphocyte type. Immunophenotyping and molecular clonality PCR were performed to confirm the cytologic diagnosis. To our knowledge, this is the first report of pericardial effusion in a dog due to T-cell lymphoma of granular lymphocyte type.
Keywords: T-cell lymphoma; dog; immunophenotyping; lymphoma of granular lymphocyte type; molecular clonality PCR; pericardial effusion.
