Individual or, occasionally, clusters of neoplasms such as fibroleiomyomas in Beluga whales (Mikaelian and others 2000) have been reported. Tumour types include epithelial, mesenchymal and, less commonly, neuroendocrine tumours (Gulland and others 2001). Renal adenoma, reticuloendotheliosis, lymphosarcoma, squamous cell carcinoma and pancreatic adenoma have been reported in Atlantic bottlenosed dolphins (Tursiops truncatus) (Gulland and others 2001). Mesenchymal tumours are less common in the species; leiomyomas of the digestive tract have been recorded only in single individuals, including in the intestine of an Atlantic white-sided dolphin (Lagenorhynchus acutus) (Geraci and others 1987) and in the stomach of a common dolphin (Delphinus delphis) (Cowan and others 1986). This short communication details the gross, histological and immunohistochemical findings of a gastric leiomyoma in an Atlantic bottlenosed dolphin. An emaciated, adult, male Atlantic bottlenosed dolphin, 268 cm in length and weighing 262·2 kg, was stranded dead off the coast of North Carolina, USA. Postmortem examination revealed lesions in the digestive, musculoskeletal, urogenital and endocrine systems. Specific gross findings were left mandibular swelling, urinary calculi in the penile urethra, focal proliferations on the penis, adrenocortical cysts, serous atrophy, a healed costal fracture and gastric trematodiasis. In the pylorus, there was a focal intramural mass measuring 3·0 cm x 2·0 cm x 2·0 cm, which was ulcerated on the mucosal surface, although luminal circumference was not reduced (Fig 1). On the cut surface, the mass was firm and white. Gastric contents were absent save for a bilious fluid. Representative sections were collected in 10 per cent formalin and processed routinely. Histologically, lesions were found in the cardiovascular, respiratory, digestive, endocrine, musculoskeletal and urogenital tracts. Specific microscopic findings unrelated to the pyloric mass included myocarditis, aortitis, pulmonary oedema, gastric trematodiasis (Braunina cordiformis), colitis, hepatic haemosiderosis, proliferative balanitis, urethritis, focal mandibular callus (present before fracture) and adrenocortical cysts. The pyloric mass was composed of plump spindyloid cells forming interlacing bundles (Fig 2a). Cells had abundant eosinophilic cytoplasm and small, elongated nuclei, with minimal anisocytosis and anisokaryosis. Mitoses were not observed. Moderate inflammation was evident, associated with plasma cells and macrophages. Based upon the histological findings, two differential diagnoses for the neoplasm were proposed: leiomyoma and gastrointestinal stromal tumour. Immunohistochemical stains were applied to identify the tumours, including the myogenic markers smooth muscle actin (SMA), muscle-specific actin (MSA) and desmin (Des), as well as cytokine markers (c-kit) and neurogenic markers (S-100). Results of staining indicated positive intracytoplasmic staining for SMA (Fig 2b) and MSA (Fig 2c), rare positive intracytoplasmic staining for c-kit and S-100, and negative staining for desmin. A leiomyoma was therefore diagnosed. Leiomyomas, which are of smooth muscle origin, exhibit positive immunohistochemical staining for SMA, MSA and desmin; however, in one study of dogs, only 62 per cent of the tumours were positive for desmin and 97 per cent were positive for SMA (Frost and others 2003). Gastrointestinal stromal tumours are proposed to arise from the interstitial cells of Cajal and exhibit positive staining for c-kit, a protooncogene that encodes for a transmembrane tyrosine kinase. Infrequent staining is observed with SMA, MSA and S-100 (Frost and others 2003). Gastrointestinal stromal tumours have been reported in human beings, dogs and horses. The gastric leiomyoma in this case was an incidental finding; the animal is likely to have died from the combination FIG 1: Tumour found in the pylorus of an Atlantic bottlenosed dolphin (Tursiops truncatus) in which the tunica media is expanded by a well-demarcated nodule (white line); the arrow indicates the gastric mucosa}, number={4}, journal={VETERINARY RECORD}, author={Rotstein, D.

Trematodes were identified as Tanaisia (Tamerlania) zarudnyi, which have a life cycle involving terrestrial snails. Trematodes have been reported within kidneys in several orders of birds, including the Columbiformes, Passeriformes, Stercorariidae, Anseriformes, Galliformes, and Piciformes. Snails were not uncommon within the barbets' aviary and may have been the source of exposure.

However, lymphoma is the most common neoplasia of the equine haematopoietic system (Savage 1998) and it is one of the leading causes of neoplasia-related death in horses (Quist and others 1994). Lymphomas are usually multicentric, involving the lymph nodes, intestine, liver, spleen, kidneys, lungs and bone marrow; cutaneous, intestinal and thymic forms have been reported less frequently in retrospective studies (Savage 1998). Large granular lymphoma is very rare in horses; three cases are described in the literature (Grindem and others 1989, Quist and others 1994, Herraez and others 2001). Although, in one report, lymphoma was isolated in the intestine, other sites of involvement included the liver, spleen, lymph nodes, kidneys and lungs. The exact lineage of large granular lymphocytes is as yet undetermined, although natural killer cell or cytotoxic T cell lines are considered likely. Large granular lymphocytes are normally present in the blood, representing up to 10 per cent of the total circulating lymphocyte pool in the young animal and decreasing in number as the animal ages (McDonough and Moore 2000). With haematoxylin and eosin stain, large granular lymphocytes have been seen to contain intracytoplasmic azurophilic granules; neoplastic cells tend to exhibit phosphotungstic acid haematoxylin (PTAH) positivity of the granules and positive immunohistochemical staining for the T lymphocyte marker CD3. The heterogeneity of granular lymphocytes with respect to the size and number of the granules, cytochemical and histochemical reactions, and biological behaviour of the neoplasms is described by Kariya and others (1997), but there are no previous reports of this type of neoplasm in a mule in the literature. This short communication describes a case of large granular lymphoma in a mule. A 10-year-old female mule was presented with chronic diarrhoea and weight loss of 160 kg over one-and-a-half months. The mule had been treated with omeprazole (Prilosec; AstraZeneca), methylprednisolone (Depo-Medrol; Fort Dodge), febendazole (Panacur; Intervet) and prophylactic floating of the teeth, but there had been no improvement in the clinical signs. At presentation, the mare was extremely underweight, with a body condition score of 2 (on a scale of 1 to 9), depressed and 5 per cent dehydrated. Its body temperature was subnormal (37°C) and the mucous membranes were pale. Rectal examination revealed bright red rectal mucosa. A complete blood count and serum chemistry indicated a neutrophilic leucocytosis with a mild left shift (17·7 x 103/litre segmented neutrophils and 1·9 x 102 bands/ litre), lymphocytosis (9·65 x 102/litre), monocytosis (3·86 x 102/litre), hypocalcaemia (10·2 mg/dl, reference range 10·6 to 13·3 mg/dl), hypokalaemia (2·1 mg/dl, reference range 2·4 to 5·5 mg/dl), hypoalbuminaemia (1·5 g/dl, reference range 2·3 to 4·6 g/dl), hypoproteinaemia (3·6 g/dl, reference range 5·3 to 8·0 g/dl) and low bicarbonate (15 mmol/litre, reference range 20 to 36 mmol/litre). A rectal biopsy indicated the presence of an intestinal lymphoma and, given the mule’s deteriorating condition, it was euthanased. At postmortem examination the liver was found to contain multiple, variably sized, yellow nodules, located on or below the capsular surface. The nodules were firm, dull and granular with a green 2 mm rim on the cut surface; occasional nodules formed adhesions with the adjacent free capsular surface of adjacent lobes. The jejunum to ileum and small colon to rectum exhibited gross proliferation of the mucosa and transmural oedema. The mesenteric lymph nodes were enlarged and oedematous. Microscopic examination revealed neoplastic lymphocytes within the liver, small intestine, large intestine and small colon in varying numbers and degrees of infiltration. Within the liver, the cells formed multifocal to coalescing nodular aggregates that effaced the hepatic architecture (Fig 1). Associated with these cells were small lymphocytes and scattered eosinophils. The neoplastic cells had abundant pale cytoplasm with small to moderate numbers of perinuclear, eosinophilic granules less than 1 μm in size, which were PTAH positive and CD3 positive. The nuclei were central to paracentral and openfaced with stippled chromatin. In the small intestine and large intestine, the lamina propria was expanded by large numbers of neoplastic cells, which infiltrated and disrupted the crypts (Fig 2); neoplastic cells also extended into the superficial tunica muscularis. Diffuse crypt necrosis, regeneration and villous atrophy were present in the small intestine. The behaviour of large granular lymphoma in animals is variable, from extremely aggressive in the Fischer rat to relatively benign in human beings, while in horses it has involved systemic spread in some cases, but not in all (Quist and others 1994). It has also been reported in cats and dogs (Kariya and others 1997, Darbes and others 1998, McDonnough and Moore 2000). In the present case, large granular lymphoma was observed in the portal regions of the liver, indicating lymphatic or vascular spread, and the presence of eosinophils sugVeterinary Record (2004) 155, 462-463}, number={15}, journal={VETERINARY RECORD}, author={Zimmerman, B and Jones, S and Rotstein, DS}, year={2004}, month={Oct}, pages={462–463} } @article{de voe_geissler_elmore_rotstein_lewbart_guy_2004, title={Ranavirus-associated morbidity and mortality in a group of captive eastern box turtles (Terrapene carolina carolina)}, volume={35}, ISSN={["1042-7260"]}, DOI={10.1638/03-037}, abstractNote={Abstract Seven captive eastern box turtles (Terrapene carolina carolina) from a large collection of North American chelonians in North Carolina became acutely ill in the fall of 2002.

The major portion of the multinodular urolith weighed 208 g and was 16 cm long × 3.7 cm diameter at the widest point. The urolith was composed of 100% struvite (magnesium ammonium phosphate) and on culture yielded Klebsiella oxytoca, a ureasepositive bacterium occasionally associated with struvite urolith formation in domestic animals.
