Abstract
Lymphoid and haematopoietic neoplasms are rare in cetaceans. This report describes intravascular lymphoma in an adult common dolphin that presented with neurological signs prior to stranding. Intravascular lymphoma is a rare neoplasm previously recorded in humans, dogs, a cat and a horse. The condition is characterized by intravascular neoplastic lymphocytic proliferation, the sequelae of which are dependent on the organ affected. Key pathological findings in this case included multifocal cerebrocortical malacia secondary to vascular occlusion associated with intravascular neoplastic lymphocytic proliferation. Immunohistochemistry supported a T-cell phenotype similar to that observed in dogs. The neurological presentation was consistent with that seen in other species in which the central nervous system is involved. The aetiology and pathogenesis have not been established in other species and although no further investigations were made in this common dolphin, this report adds to the short list of species affected by this rare neoplasm.
期刊介绍:
The Journal of Comparative Pathology is an International, English language, peer-reviewed journal which publishes full length articles, short papers and review articles of high scientific quality on all aspects of the pathology of the diseases of domesticated and other vertebrate animals.
Articles on human diseases are also included if they present features of special interest when viewed against the general background of vertebrate pathology.
