RESUMO O objetivo do presente trabalho foi relatar um caso de leishmaniose visceral com apresentação mucosa em um cão com hiperadrenocorticismo. Um canino, macho, da raça Poodle, 11 anos de idade, foi atendido com histórico de disfagia, halitose e sialorreia. Ao exame físico, observou-se linfadenomegalia generalizada e alterações cutâneas, como rarefação pilosa, comedões, telangiectasia e atrofia cutânea. Além disso, o animal também apresentava formações orais localizadas na língua. Dos exames hematológicos e bioquímicos realizados, a única alteração encontrada foi elevação da fosfatase alcalina (1724u/L). O teste de supressão com a dexametasona em dose baixa foi executado para investigar hiperadrenocorticismo, tendo resultado positivo. Também foram realizados exames citológicos dos linfonodos, da medula óssea e das formações orais, tendo sido observada a presença de formas amastigotas de Leishmania sp. em todas as amostras. O animal foi submetido à biópsia incisional das formações orais, e a análise histopatológica demonstrou um quadro de inflamação granulomatosa com presença de grande quantidade de microrganismos morfologicamente compatíveis com formas amastigotas de Leishmania sp. no interior das células inflamatórias. Diante dos achados clínicos e dos exames complementares, diagnosticou-se um caso de leishmaniose com manifestação mucosa atípica, associado ao hiperadrenocorticismo, podendo essa endocrinopatia ter sido um fator predisponente para essa enfermidade infectocontagiosa.

ABSTRACT The objective of the present study was to report a case of visceral leishmaniasis with mucosal presentation in a dog with hyperadrenocorticism. A canine, male, Poodle, 11 years old, was attended with a history of dysphagia, halitosis, and sialorreia. The physical examination revealed generalized lymphadenomegaly and cutaneous alterations such as hair loss, comedones, telangiectasia, and cutaneous atrophy. Futhermore, the animal also had localized oral formations on the tongue. From the hematological and biochemical tests performed, the only alteration was alkaline phosphatase elevation (1724u / L). The low dose dexamethasone suppression test was performed to investigate hyperadrenocorticism and found a positive result. In addition, cytological exams of lymph nodes, bone marrow and oral formations were also performed, and the presence of amastigote forms of Leishmania sp. were observed in all samples. The animal was submitted to incisional biopsy of the oral formations and the histopathological analysis showed a granulomatous inflammation with presence of large quantity of microorganisms morphologically compatible with amastigotes forms of Leishmania sp. within the inflammatory cells. Faced with clinical findings and complementary exams, a case of leishmaniasis with atypical mucosal manifestation, associated with hyperadrenocorticism, was diagnosed, and this endocrinopathy could have been a predisposing factor to this infectious-contagious disease.

RESUMO O objetivo do presente trabalho foi relatar a eficácia do fluralaner no tratamento da demodicidose juvenil generalizada canina. Dois caninos, apresentando dois e três meses de idade, com diagnóstico clínico e parasitológico de demodicidose generalizada, foram tratados com administração única de fluralaner, na dose recomendada em bula pelo fabricante. Além disso, foi realizada a terapia adjuvante à base de xampu de peróxido de benzoíla e domperidona. Observou-se uma resposta terapêutica satisfatória, com repilação completa ao 30º dia após a administração do fármaco. Para cada paciente, foi realizado exame parasitológico do raspado cutâneo aos 75 e 90 dias seguintes ao início do tratamento, e todos foram negativos. Tendo em vista a elevada eficácia do tratamento proposto, sugere-se a inclusão do fluralaner nos protocolos terapêuticos destinados à demodicidose canina, particularmente nos pacientes pediátricos e com a forma generalizada da doença.

ABSTRACT The aim of the present study was to report the efficiency of fluralaner on the treatment of two cases of canine generalized juvenile demodicosis. Two puppies, aging two and three months old, with the clinic and parasitological diagnosis of generalized demodicosis were treated with single administration of fluralaner. according to the dose recommended by the responsible laboratory. Additionally, adjuvant therapy was applied using benzoyl peroxide shampoo and domperidone. A satisfactory therapeutic response was observed, and complete repilation was present at the 30th day after drug administration. For each patient, at the 75th and 90th day after the treatment began, skin scrapings were performed in order to investigate the presence of Demodex sp; and all were negative. Considering the high efficiency of the treatment used, we suggest the inclusion of fluralaner on the therapeutic protocol for canine demodicosis, particularly in pediatric patients and with the generalized form of the disease.

ABSTRACT Adenomyosis, a non-neoplastic myometrial proliferation, is a rare pathologic condition in domestic animals, of unknown etiology. There is a lack of information about the clinical and pathological features of this disease in cats, therefore just a few reports in that species. The study describes a case of adenomyosis in a feline female. A cat, six years old, undefined breed, not spayed, had abdominal swelling history and vaginal discharge. Clinically, upon abdominal palpation, a diffuse increase suggesting a uterine change was found. The vulva had sanguine-purulent exudates. The choice was for the neutering surgical. Uterine macroscopy revealed cystic endometrial hyperplasia/pyometra in uterine horns, and the presence of a diffuse mass on uterine corpus. Fragments of the mass were sent for histopathological analysis, which revealed adenomyosis of the uterine corpus. The patient exhibited adequate post-operative recovery. The adenomyosis should be considered as a differential diagnosis of uterine neoformation in domestic cats.
