“…4,6,11,18 Although uncommon, there are several case reports of hemangiosarcoma in other species. 1,5,[7][8][9][10][12][13][14][15][16] There is limited information on the biological behavior of nonvisceral hemangiosarcomas. 9,18 This retrospective study was conducted to gather information about the signalment, frequency of occurrence, and clinical outcome of nonvisceral hemangiosarcomas and to attempt to find patterns in the clinical history or histologic features that correlate with the outcome.…”

Abstract. Cases of hemangiosarcoma submitted to the Colorado State University Veterinary Diagnostic Laboratory during a 6-year period were reviewed. Visceral hemangiosarcomas represent less than 2% of canine specimens submitted for histologic examination and nonvisceral hemangiosarcoma less than 1%. Most nonvisceral hemangiosarcomas of dogs occur in skin. Hemangiosarcomas are less common in cats and usually occur in skin. They are also rare in other animal species. Animals with nonvisceral hemangiosarcomas are usually mature; dogs and cats average 10 years of age. The tumors develop in many different locations, and there is no sex predilection. A wide variety of dog breeds are affected, but Italian greyhounds, greyhounds, and whippets are overrepresented. Clinical outcomes of 76 cases of nonvisceral hemangiosarcomas in dogs and cats were obtained from submitting veterinarians. Completeness of excision of a tumor is the most important factor that can be used in predicting clinical outcome for an affected dog or cat. In all cases in which the animals were clinically normal for at least 1 year after surgical removal of a nonvisceral hemangiosarcoma, the margins were reported to be free of neoplastic cells. Degree of differentiation, mitotic rate, size of tumor, and presence or absence of epidermal ulceration, mast cells, or solar elastosis did not correlate with clinical outcome.

“…32 However, adenocarcinoma is the most common primary renal tumor found. 33 Other tumors that have been identified less frequently include transitional cell carcinoma, nephroblastoma, hemangiosarcoma and adenoma. 33 Many of these primary tumors will form mass lesions (often unilateral), whereas lymphoma may cause non-specific changes to the kidney(s) visible on ultrasound as hyperechoic cortices, hypoechoic nodules, renomegaly and subcapsular effusion.…”

The presence of hypoechoic subcapsular thickening is considered fairly suggestive of renal lymphoma and, in one study, 80% of cats with this ultrasonographic finding were diagnosed This knowledge has, in turn, facilitated the development of therapies that are tailored for specific conditions.…”

Practical relevance: Acute kidney injury (AKI) is a frequently recognized disease process in cats that requires immediate and aggressive intervention. A thorough understanding of the pathophysiologic processes underlying AKI and familiarity with the most common etiologies are essential for providing the most effective and timely therapy. Possessing this knowledge will also allow a more accurate prognosis to be given, and afford the best chance of a favorable outcome. Clinical challenges:Feline patients often present with vague signs of AKI, which may delay treatment and adversely affect the prognosis. Their response to injury and treatment is often different to that of other species.Audience: This two-part review article is directed at small animal practitioners as well as specialists. Part 1 reviews mechanisms underlying AKI in the cat, as well as etiologies and treatments related to some specific causes of AKI. New terminology -and a new emphasisAcute kidney injury (AKI) is a relatively new term in the nephrology literature that largely replaces the use of 'acute renal failure' (ARF). Originally introduced in the human literature, AKI allows for greater stratification of cases with regard to severity and prognosis. By suggesting that a patient has injury, rather than failure, one can recognize the potential for earlier treatment and recovery. In human medicine, the older term 'ARF' refers only to patients requiring renal replacement therapy (RRT). Additionally, the more common term 'kidney', rather than 'renal', facilitates communication with and understanding by clients of AKI. The incidence of AKI in cats is not known, but it is not uncommon and can be caused by a variety of different insults. A uniform definition for AKI does not exist in the veterinary literature and varies among publications. Generally accepted criteria include an abrupt reduction in kidney function resulting in alterations in glomerular filtration, urine production and tubular function. These alterations result in an inability to maintain fluid, electrolyte and acid-base balance, and may lead to azotemia. PathophysiologyThe pathophysiology of AKI is complex, but can be described by four stages: initiation, extension, maintenance and recovery.

“…In domestic cats, the most prevalent urinary tract tumors are lymphoma, especially those involving the kidney, nevertheless primary renal tumors are considered rare and aggressive neoplasms (Henry et al 1999, Wilson et al 2007. Primary epithelial tumors of the urinary tract include TCC and squamous cell carcinoma (Henry et al 1999).…”

“…Primary epithelial tumors of the urinary tract include TCC and squamous cell carcinoma (Henry et al 1999). Among urinary bladder tumors, 90% are epithelial and malignant, wherein the TCC is the most frequent, representing 50 to 75% of malignant urinary bladder tumors (Norris et al 1992, Rocha et al 2000, Henry 2003.…”

Transitional cell carcinoma of urinary bladder with metastasis in lumbar vertebrae and spinal cord compression in an ocelot(Leopardus pardalis)

AbSTRACT.-Nakagaki K.Y.R., Lima P.A., Utiumi K.U., Pires M.A.M., Zanatta R., Boabaid F. This paper reports a case of nonpapillary and infiltrative transitional cell carcinoma (TCC) of the urinary bladder with metastasis of lumbar vertebrae and spinal cord compression in an adult female ocelot (Leopardus pardalis), from the Mato Grosso state, Brazil. The ocelot had pelvic limb paralysis and skin ulcers in the posterior region of the body and was submitted to euthanasia procedure. At necropsy was observed a multilobulated and irregular shaped, yellowish to white nodule in the urinary bladder. The nodule had a soft consistency and arised from the mucosa of the urinary bladder extending throughout the muscular layers and the serosa. Nodules of similar appearance infiltrating the vertebral column the at L6 and L7 vertebrae with corresponding spinal canal invasion were also observed. The histological evaluation showed epithelial neoplastic proliferation in the urinary bladder with characteristics of nonpapillary and infiltrative TCC, with positive immunohistochemical staining for pancytokeratin, and strong immunostaining for cytokeratin of low molecular weight, and weak or absent labeling for high molecular weight cytokeratin. This is the first report of TCC of urinary bladder in ocelot in Brazil.INDEX TERMS: Transitional cell carcinoma, urinary bladder, ocelot, Leopardus pardalis, epithelial neoplasia, urinary system, immunohistochemistry, cytokeratin, wild feline.
