猫乳腺瘤的发病率仅次于皮肤癌和淋巴肉瘤，与犬乳腺肿瘤的发生率相比较，猫的发病率不及其半。然而，犬的乳腺肿瘤509／6以上是良性的，与其相反猫的乳腺肿瘤709／6～90％为恶性的、转移性的；在肿瘤间质和实质细胞间，常有淋巴细胞浸润；淋巴转移常发生在腋下淋巴结、腹股沟淋巴结、肺、肝及脾，骨骼的转移性肿瘤很少见。 相似文献

A 10-year-old, neutered female, domestic shorthair cat was presented with a recent history of weight loss, polydipsia, diarrhoea and vomiting. On physical examination, intestinal thickening and mesenteric lymph node enlargement were apparent. Clinical investigations revealed peripheral blood eosinophilia, eosinophilic abdominal effusion and eosinophilic mesenteric lymphadenitis. There was a temporary response to treatment with glucocorticoids but signs progressed and the cat was euthanased. On histology, there was eosinophilic infiltration and fibroplasia of intestine and mesenteric lymph nodes. Large aggregates of neoplastic round cells in the intestine and lymph nodes were identified as T lymphocytes using immunohistochemistry. A diagnosis of intestinal T cell lymphosarcoma was made. This case demonstrates that hypereosinophilic paraneoplastic syndrome may occur in cats with lymphosarcoma. Eosinophil chemotaxis may be a response to the production of interleukin-5 by neoplastic lymphocytes. 相似文献

Chronic intermittent vomiting in a cat: a case of chronic lymphocytic-plasmacytic gastritis

下载免费PDF全文 A 3-year-old cat presented for chronic intermittent vomiting was diagnosed with chronic lymphocytic-plasmacytic gastritis via histological examination of an endoscopic gastric biopsy. The condition was effectively managed with prednisone. The author cautions against missing a diagnosis of alimentary lymphosarcoma without a full-thickness gastric biopsy. 相似文献

The clinical and radiological features of 30 cases of anterior mediastinal lymphosarcoma in the cat are described; they represented 48 per cent of all cases of lymphosarcoma recorded at the University of Bristol Veterinary School between 1972 and 1977. The condition principally affected young cats and there was a predisposition in oriental breeds. Dyspnoea and regurgitation were the two most common major presenting signs. Diagnosis was made in most cases on the basis of radiological examination, but in some cytological examination of the thoracic fluid was necessary for confirmation. 相似文献

OBJECTIVE: To determine the efficacy of doxorubicin when used alone in inducing remission in cats with lymphosarcoma. DESIGN: Prospective multi-institutional study of naturally occurring disease. METHODS: Cases were accrued from veterinary institutions in Australia and New Zealand after obtaining consent from informed owners. Cats were treated with doxorubicin every 3 weeks for three treatments. If there was no response to the first dose of doxorubicin or if the cat relapsed during the doxorubicin regimen, the cat was withdrawn from the trial and either euthanased or treated with other agents. Age, breed, gender and anatomic site of the lymphosarcoma (multicentric, alimentary, mediastinal, extranodal) were recorded for each cat. Clinical remission was assessed before each treatment by physical examination, radiography, ultrasonography and computed tomography where appropriate. Complete remission was defined as the disappearance of all clinical signs and clinically detectable tumour. RESULTS: Twenty-one cases were accrued over a 2-year-period but only 19 were available for data analysis. Young Siamese cats were over-represented and all cats with mediastinal tumours were young Siamese. There was a significant difference between the mean ages of cats with mediastinal or multicentric lymphosarcoma (mean +/- SD: 3.5 +/- 3.0 and 4.3 +/- 2.6 years, respectively) and cats with alimentary or extranodal LSA (11.4 +/- 0.9 and 11.0 +/- 0.9 years, respectively). Of 19 cats treated with doxorubicin alone, 6 (32%) had complete remission, 6 (32%) had partial remission and 7 (36%) did not respond. CONCLUSIONS: The results suggest that doxorubicin cannot be recommended as a single agent for treatment of feline lymphosarcoma because of the rather poor remission rate achieved. 相似文献

Systemic mastocytoma was diagnosed in a 16 year old cat. Prednisone therapy was initiated but discontinued after 11 months because of development of a duodenal ulcer. Twenty months after the initial diagnosis the cat developed dyspnea, due to enlarged pharyngeal lymph nodes. Euthanasia was performed; systemic mastocytoma and lymphosarcoma were found at necropsy. 相似文献

Three horses with clinical signs compatible with pleural effusion were examined with diagnostic ultrasound. In one of the three horses, confirmed septic pleural effusion was monitored with ultrasound during a successful treatment regimen. Eficacy of thoracentesis and detection of recurrence of fluid were readily determined. In the second horse, diagnosis of diffuse pleural neoplasia (lymphosarcoma) was made. In the third horse presented for pleural effusion, the effusion was documented and concurrent ascites detected with ultrasound. Carcinomatosis was found at necropsy. Ultrasound examination proved to be a sensitive, noninvasive modality useful in diagnosis and treatment of pleural effusion. 相似文献

Cysts of the protozoan Sarcocystis sp were found in skeletal and cardiac musculature in a 1.5-year-old cat with lymphosarcoma. The cat was FeLV-positive and had grossly visible neoplastic involvement of the spinal cord, mediastinum, bone marrow, and kidneys. Ultrastructural examination of the parasitic cyst wall suggested that the species in this case was different from that described in the only other reported case. It was hypothesized that immunosuppression from FeLV infection permitted an aberrant life cycle with encystment of Sarcocystis sp in this cat. 相似文献

A two-year-old female alpaca with multicentric lymphosarcoma presented because of progressive weakness and recumbency. The diagnosis of lymphosarcoma was based on the detection of immature and atypical lymphocytes in a lumbosacral CSF sample. Post mortem examination confirmed multicentric lymphosarcoma involving multiple organs. Immunophenotyping using cross reactive T- and B-cell antibodies characterized the tumour as a T-cell lymphosarcoma. 相似文献
