Resumo: | After skin tumors and lymphohematopoietic tissue, mammary neoplasms are most common in domestic cats. Mammary carcinomas of cats have poor prognosis, since such tumors are very aggressive and with great ability to generate metastases. The aim of this study was to characterize the point of view histopathological, histochemical and immunohistochemical, spontaneously occurring mammary tumors in cats. Thirty-five samples of tumor tissue were collected surgically and histological sections were stained with hematoxylin-eosin (HE) for histopathological analysis. For histochemical analysis, were used the Masson’s Trichrome and Periodic Acid Schiff (PAS) to evaluate the deposition of collagen and glycosaminoglycans associated with tumors, respectively. To perform the immunohistochemistry assays were used anti-Ki-67, anti-PCNA and anti-Bcl-2. The obtained results showed that 14.29% of the lesions were classified as benign (fibroadenoma, adenoma and simple adenosis) and 85.71% as adenocarcinomas. Malignant neoplasms were multifocal, predominantly of invasive growth pattern, presence of necrosis, mitotic figures, and inflammatory infiltrate. The histochemical analysis revealed that the malignant lesions exhibited moderate to strong staining pattern when stained with PAS and weak to moderate with MT. Marking anti-Ki-67 showed cytoplasmic and nuclear pattern in well-differentiated malignant cells in tumor tissue. The protein Bcl-2 showed membrane pattern restricted to the processed tissue and the tissue marked with anti-PCNA showed nuclear and cytoplasmic pattern in glandular cells, occasionally in stromal cells of epithelioid appearance. In summary, the large number of mitotic figures and increased reactivity to staining with anti-PCNA antibody suggests neoplasms with intense proliferative activity indicating a poor prognosis for affected individuals. |

Os carcinomas mamários de gatas possuem prognóstico desfavorável, uma vez que tais tumores são bastante agressivos e com grande capacidade de gerar metástases. Objetivou-se com esse estudo, caracterizar sob o ponto de vista histopatológico, histoquímico e imunoistoquímico; neoplasias mamárias de ocorrência espontânea em gatas. Trinta e cinco amostras de tecido neoplásico foram coletadas cirurgicamente e os cortes histológicos foram corados pela Hematoxilina-Eosina (HE), para estudo histopatológico. Para análise histoquímica, utilizou-se o Tricromico de Masson e Ácido Periódico de Schiff (PAS), para avaliar os depósitos de colágeno e glicosaminoglicanos associados aos tumores, respectivamente. Para realização dos ensaios imunoistoquímicos foram utilizados os anticorpos anti-Ki-67, anti-PCNA e anti-Bcl-2. Nos resultados obtidos observou-se que 14,29% das lesões foram classificadas como benignas (fibroadenoma, adenoma simples e adenose) e 85,71% como adenocarcinomas. As neoplasias malignas eram multifocais, de padrão de crescimento predominantemente invasivo, com presença de necrose, figuras de mitose, e infiltrado inflamatório. As análises histoquímicas revelaram que as lesões malignas apresentavam padrão de coloração moderada a forte quando coradas com PAS e fraca a moderada com Tricrômico de Masson. A marcação anti-Ki-67 apresentou padrão citoplasmático e nuclear em células malignas bem diferenciadas no tecido neoplásico. A proteína Bcl-2 apresentou padrão membranar restrito ao tecido transformado e o tecido marcado com o anticorpo anti-PCNA, demonstrou padrão citoplasmático e nuclear em células glandulares, ocasionalmente em células estromais de aspecto epitelióide. Em resumo, a grande quantidade de figuras de mitose e a maior reatividade à marcação com o anticorpo anti-PCNA sugere neoplasmas com intensa atividade proliferativa evidenciando um mau prognóstico para os indivíduos portadores.Submitted by (edna.saturno@ufrpe.br) on 2016-10-10T14:58:02Z No. of bitstreams: 1 Giuliana Viegas Schirato.pdf: 2698527 bytes, checksum: 33a822ba864e7a3747d0b9dd0d006691 (MD5)Made available in DSpace on 2016-10-10T14:58:02Z (GMT).

After skin tumors and lymphohematopoietic tissue, mammary neoplasms are most common in domestic cats. Mammary carcinomas of cats have poor prognosis, since such tumors are very aggressive and with great ability to generate metastases. The aim of this study was to characterize the point of view histopathological, histochemical and immunohistochemical, spontaneously occurring mammary tumors in cats. Thirty-five samples of tumor tissue were collected surgically and histological sections were stained with hematoxylin-eosin (HE) for histopathological analysis. For histochemical analysis, were used the Masson’s Trichrome and Periodic Acid Schiff (PAS) to evaluate the deposition of collagen and glycosaminoglycans associated with tumors, respectively. To perform the immunohistochemistry assays were used anti-Ki-67, anti-PCNA and anti-Bcl-2. The obtained results showed that 14.29% of the lesions were classified as benign (fibroadenoma, adenoma and simple adenosis) and 85.71% as adenocarcinomas. Malignant neoplasms were multifocal, predominantly of invasive growth pattern, presence of necrosis, mitotic figures, and inflammatory infiltrate. The histochemical analysis revealed that the malignant lesions exhibited moderate to strong staining pattern when stained with PAS and weak to moderate with MT. Marking anti-Ki-67 showed cytoplasmic and nuclear pattern in well-differentiated malignant cells in tumor tissue. The protein Bcl-2 showed membrane pattern restricted to the processed tissue and the tissue marked with anti-PCNA showed nuclear and cytoplasmic pattern in glandular cells, occasionally in stromal cells of epithelioid appearance. In summary, the large number of mitotic figures and increased reactivity to staining with anti-PCNA antibody suggests neoplasms with intense proliferative activity indicating a poor prognosis for affected individuals. |
