and dogs from T-cell lymphomas

Melbourne, Australia – mechentel news – Conjunctival lymphoma is well documented in the medical literature, but veterinary reports are few. C. McVCowan et al. fromniversity of Melbourne Veterinary Clinical Centre, Melbourne, Australia reported in the issue of August from Vet. Ophthalmol. five cases of canine lymphoma, and three of feline in which the presenting sign was conjunctival involvement. All animals were in apparently good health at the time of presentation, and attended the referring clinic because of conjunctival disease. One dog showed generalized lymphadenopathy at presentation, although the ocular lesion was the reason for consultation, but all other patients were well with no detectable disease beyond the eye. All cats were presented for their ocular disease. All dogs were confirmed to have T-cell tumors, although the histological appearance of these was variable. In contrast, all cats had B-cell tumors. Referring clinicians and owners were contacted for follow-up information. Three dogs had been euthanased within 6 months of diagnosis for deterioration of general health. The remaining two were alive and showed no signs of systemic disease. Two cats had good survival following diagnosis, the other died of lesions that may not be related.
