“…17 Similar to mast cell disease, lymphosarcoma may also present as either nodular or diffuse disease, with transmural thickening associated with altered to absent layering. 8,15 The most common solitary site is the ileocolic junction. 8,15 In contrast to round cell tumors, adenocarcinoma often appears as a focal (ring-like) lesion with circumferential bowel wall thickening with loss of layers and subsequent mechanical ileus.…”

Four cats with feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) are described. Clinical signs included decreased appetite, weight loss, vomiting and diarrhea. Bloodwork abnormalities included mild neutrophilia (n = 2) and hyperglobulinemia with concurrent hyperproteinemia (n = 2). Ultrasonographically, a total of five solitary masses with mural thickening and loss of layering were identified in the stomach, duodenum, jejunum and colon. In one cat a second, separate lesion was diagnosed 3 weeks following surgical resection of one mass. Histopathologically, lesions were characterized by collagen trabeculae and mixed inflammatory cell infiltrates, predominantly eosinophils. Multiple areas of necrosis were also noted, which contained bacteria in 2/4 cats. In two cats, changes consistent with FGESF were also noted in the liver. All cats had surgical resection of their lesions. Two cats are still living at time of publication (43 and 24 months post-surgery). FGESF should be considered as a differential for intestinal masses in cats.

“…Today, ultrasound technique also involves ultrasonographic imaging, which has the major advantage that the "landscape" of the internal organs and skeleton is visible. Ultrasonographic measurements distress animals relatively little and are commonly used in humans and animals for diagnostic purposes (e.g., Grooters et al 1994;Lambertz et al 1995) and in the context of animal production (e.g., Perkins et al 1992;Herring et al 1994;Chiba 1995). Ultrasonography has been used in a few ecophysiological studies (e.g., Sears 1988;Newton 1993;Reimers et al 1993;Woodroffe 1995;Haefner et al 1996).…”

Organs, even of fully grown adult birds, mammals, and reptiles, may show substantial size changes in relation to specific performances. These changes are difficult to study, because measurements usually can only be obtained following the death of the animal. We explored the use of ultrasonographic imaging, a relatively simple noninvasive technique, to measure size of pectoral muscles and stomach in two small shorebird species (red knots Calidris canutus and golden plovers Pluvialis apricaria). Accuracy of ultrasound measurements in estimating organ mass in red knots was reasonably high. Depending on the equipment used, the error of individual measurements was 20%-25% for the pectoral muscles and 26%-44% for the stomach. In plovers the technique was less accurate, probably because of the low variability of the organs involved. Ultrasound scanning is particularly suited to measure rapidly changing organ sizes over short time intervals. We demonstrate this with an example in which changes in individuals in size of pectoral muscle and stomach were monitored in captive red knots following a change in diet. Ultrasound measures will enable studies on the links between body composition and future behavior and physiology.

“…However, further studies are needed to establish references values. Ultrasonography is determinant in the diagnosis of intestinal lymphoma and can detect or confirm the structure of an abdominal mass as observed in our case but also can show symmetrical and peripheral thickening of the intestinal wall with homogeneity and hypoechogenicity [3]. However, to obtain a definitive diagnosis of intestinal lymphoma, cytology, histology and phenotyping by immunohistochemistry are crucial.…”

ABSTRACT. A 10-year-old male fossa (Crytoprocta ferox) exhibited clinical signs of diarrhea, anorexia and weight loss. Chemistry values and echographic results were suggestive of intestinal lymphoma. Postmortem examination revealed severe multifocal wall thickening of the small intestine with severe enlargement of the pancreatic lymph node. Microscopically, the small intestine was multifocally transmurally infiltrated by large neoplastic round cells also found in the pancreatic lymph node and the liver. On immunohistochemistry, the neoplastic cells stained intensely with CD3 and didn't stain with CD79a. Based on these findings, a diagnosis of intestinal T-cell lymphoma with pancreatic lymph node and liver involvement was made. To the authors' knowledge, this is the first report of a lymphoma with immunohistochemical phenotyping in a fossa. KEY WORDS: fossa, immunohistochemistry, small intestine, T-cell lymphoma.doi: 10.1292/jvms.12-0229; J. Vet. Med. Sci. 75(2): 183-185, 2013 Lymphoma is one of the most common tumor occurring in domestic and wild animals, especially in cats [6]. In this species, several anatomical forms are described, and the alimentary form is one of the most frequent [5]. Little is known about diseases in Eupleridae, and the majority of the reports found in the literature concerns infectious diseases [2]. To date, there is no description of any tumor in fossa. Moreover, no biological information is available in this species. Therefore, we report a case of a spontaneous intestinal T-cell lymphoma in a captive fossa (Cryptoprocta ferox) and provide biochemical, hematological and immunohistochemical data.A 10-year-old male fossa born in captivity was anesthetised with Tilétamine/Zolazepan (4 mg/kg intramuscular) for clinical examination following few days of diarrhea, anorexia, and weight loss. Fecal samples submitted for bacteriology and parasitology were normal. Clinical examination revealed a mild gingivitis associated with abundant tartar on the first left superior premolar. Tartar was extracted by ultrason, and spiramycine/metronidazole [16.67 mg/kg for 10 days per os (PO)] were given as well as meloxicam (0.1 mg/kg for 5 days PO). A blood sample was collected during anesthesia. A complete blood count (CBC) and serum biochemistry were performed and compared to values obtained from a 18-year-old healthy female fossa used as a control. The CBC showed moderately increased segmented neutrophils attributed to the gingivitis. Serum biochemistry revealed low cholesterol, decrease slight of total protein associated with hypoalbuminemia, increase slight of hepatic transaminases and lactate deshydrogenases (Table 1). Digestive signs recurred one month later, and a second anesthesia was performed. Abdominal palpation revealed a nodular mass in the cranial part of the abdominal cavity and a thickened intestinal wall. A new blood sample was collected. Compared to the previous values, the serum biochemistry confirmed the decreased cholesterol and total protein, and the increased hepatic transaminases a...
