RESUMO
Background: Sertolioma is a slow-growing, non-invasive, firm and nodular tumor, malignant in 10% to 22% of cases andwith low metastatic potential. Old age and cryptorchidism increase up to 26 times its chances of development and associates it with malignancy. Paraneoplastic syndrome, shown in 20% to 30% of the animals, is due to the aromatization oftestosterone or the direct production of estrogen by tumor cells, leading to signs of feminization and bone marrow aplasia.The objective of this article is to report a case of sertolioma in a dog with dermatological characteristic symptoms, butpresenting an unusual aggressive behavior, both completely reverted after castration.Case: A 9-year-old, uncastrated, aggressive and uncontrollable Canadian Husky dog was treated at the InstitutionalVeterinary Hospital with parapenial volume increase and generalized alopecia. A scrotal testis of reduced size and flaccid consistency and a mass in a parapenial region of 11 x 7.5 x 8 cm in diameter, with a cystic contour, adhered to theabdominal musculature and painless to palpation were detected. Cytology of the parapenial mass presented an imagecompatible with seminoma or sertolioma, and the preputial smear revealed a predominance of superficial cells. Ultrasoundexamination showed a heterogeneous inguinal mass, with expansive cystic area, compatible with mass in retained inguinaltestis. Therapeutic course consisted of bilateral orchiectomy. Ectopic testis was firm to the cut, had whitish to yellowishcoloration and was surrounded by a tunica containing 200 mL of serosanguinolent liquid. The histology of the mass revealed sertolioma-compatible cell characteristics, with cell proliferation circumvented by fibrous connective tissue formingpoorly delimited lobes, moderate polymorphism with elongated cells, arranged in a palisade at the periphery of the lobes,vacuolated eosinophilic cytoplasm and vesiculous...(AU)

La estenosis pulmonar (EP) es un defecto cardíaco congénito relativamente común en perros, puede estar presente solo o en asociación con otros defectos cardíacos congénitos como la displasia tricuspidea (DT). Ambas condiciones pueden conducir a insuficiencia cardíaca derecha. El presente trabajo pretende revisar brevemente la literatura y describir el caso citado de un perro, 10 meses, raza blue heeler que fue atendido con disminución del apetito, aumento del volumen abdominal y disnea. Después del tratamento inicial se realizó examen ecocardiograma, que era compatible con estenosis pulmonar y displasia tricuspídea.
Pulmonic stenosis (PS) is a relatively common congenital heart defect in dogs and may be present alone or in association with other congenital heart defects such as tricuspid dysplasia (TD). Both conditions can potentially lead right heart failure. This paper aims to describe a case of a 10-month old blue heeler dog which was presented with a history of decreased appetite, increased abdominal volume and dyspnea. After the first medical aid, the animal was sent to echocardiogram, which was compatible with pulmonic stenosis and tricuspid dysplasia.
A estenose pulmonar (EP) é uma cardiopatia congênita relativamente comum em cães, podendo estar presente isoladamente ou em associação a outras cardiopatias congênitas, como a displasia de válvula tricúspide (DT). Ambas as condições podem potencialmente levar a insuficiência cardíaca congestiva direita. Esse trabalho tem como objetivo descrever o caso de um cão de 10 meses da raça blue heeler atendido com histórico de hiporexia, aumento de volume abdominal e dispneia. Após o atendimento inicial, o animal foi encaminhado para exame de ecocardiograma que mostrou imagem compatível com estenose pulmonar e displasia de tricúspide.
