Carcinoma mamário com metástase pulmonar em tatu-peba (Eupharactus sexcinctus) / Breast carcinoma with pulmonary metastasis in armadillo (Eupharactus sexcinctus)

Background: Breast neoplasms are among the most common neoplastic conditions affecting domestic animals and are considered the most common type of cancer affecting women, bitches, and cats. However, there are few reports on breast neoplasms in wild animals, and there is no record of their occurrence in armadillos worldwide. Breast neoplasms are hormone-dependent neoplasms that often cause lymph node and pulmonary metastases. The diagnosis is based on the patients history, complete physical examination, and complementary tests. Here we report a case of mammary neoplasia with pulmonary metastasis in an armadillo (Euphractus sexcinctus).Case: A senile female armadillo was referred to us for treatment with a history of hyporexia and nodules in both breasts. Ultrasonographic examination revealed a hypoechogenic nodular lesion with a cross-section of approximately 1.3 × 1.4 cm and well-defined borders. The lesion had a circumscribed aspect in the left mammary gland. In the right mammary gland, there was a heterogeneous lesion with cystic formations and anechoic content. Cytopathological examination of the nodules was performed by fine needle aspiration cytology and revealed the presence of epithelial cells with ovoid and aberrant nuclei, anisocariasis, binucleation, coarse chromatin, and a high nucleus to cytoplasm ratio suggestive of carcinoma. The animal had a lean body score due to hyporexia that had evolved to anorexia and was undergoing supportive treatment. Nevertheless, the animal died two months after the cytologic diagnosis. A necropsy was performed. Cutting of the breast nodules revealed a hardened pale yellow material. The animal had pronounced pleural effusion, hemorrhage, and numerous pale yellow nodules of various sizes with firm consistency throughout the lung parenchyma. It also had hepatomegaly and splenomegaly.[...](AU)

Extrusão de disco intervertebral em mão-pelada (Procyon cancrivorus) - relato de caso / Intervertebral disc extrusion in crab-eating raccoon (Procyon cancrivorus) - case report / Extrusión de disco intervertebral en mapache lavador (Procyon cancrivorus) - reporte de un caso

O mão-pelada (Procyon cancrivorus) é um carnívoro silvestre amplamente distribuído no Brasil, porém há escassez de informações sobre a anatomia e as alterações clínicas dessa espécie. Relata-se o caso de uma fêmea de mão-pelada de cativeiro de doze anos, encaminhada para exame tomográfico da coluna vertebral, com histórico de paralisia aguda de membros pélvicos. Após a realização do exame, a análise das imagens demonstrou extrusão discal no espaço intervertebral entre T13 e L1, com sinais de compressão da medula. Optou-se pelo tratamento cirúrgico, entretanto, o manejo no período pós-operatório foi dificultado. Não houve melhora significativa dos déficits neurológicos, e posteriores complicações secundárias agravaram o quadro clínico geral, que evoluiu para óbito. Destaca-se que os relatos de extrusão de disco intervertebral em animais silvestres são raros, não havendo descrições em mãos-peladas.(AU)

The crab-eating raccoon (Procyon cancrivorus) is a wild carnivore widely distributed in Brazil, but information about the anatomy and main diseases that affect this species is scarce. This paper describes the clinical and diagnostic aspects of a 12-year-old female raccoon referred to a CT scan of the thoracolumbar spinal segment after presenting signs of acute pain and paralysis of hind limbs. Analysis of the images revealed the presence of mineralized material within the vertebral canal at the level of the T13-L 1 intervertebral space, with signs of spinal cord compression. We opted for surgical treatment. However, post-operative care was difficult, there was no significant improvement in neurological deficits, and secondary complications worsened the clinical status, which eventually led to the death of the animal. It is worth noting that descriptions of intervertebral disc extrusions in wild animals are rarely mentioned in the literature, and there are no descriptions of their occurrence in raccoons.(AU)

El mapache (Procyon cancrivorus) es un carnívoro silvestre de amplia distribución en Brasil, aunque son escasas las informaciones relacionadas con la anatomía y las alteraciones clínicas de esta especie. El presente trabajo relata el caso de una mapache de doce años, mantenida en cautiverio, que fue derivada para la realización de un examen tomográfico de la columna vertebral, con histórico de parálisis aguda de miembros posteriores. El análisis de las imágenes demostró la presencia de una extrusión discal en el espacio intervertebral entre T13 y L1, con signos de compresión medular. Se decidió realizar el tratamiento quirúrgico, aunque el manejo postoperatorio se mostró complicado. No hubo mejoría significativa de las alteraciones neurológicas, y complicaciones secundarias fueron agravando el cuadro clínico general, que llevaron a la muerte del animal. Los relatos de extrusión de disco intervertebral en animales silvestres son raros, y no se encontraron descripciones en mapaches.(AU)
