“…A remoção cirúrgica é indicada em casos onde o papiloma ocular causa sinais como hiperemia e blefaroespasmo, como apontado por Silva (2013), sendo esses sinais observados foi realizada a excisão cirúrgica do nódulo. O tratamento da papilomatose de acordo com Vieira & Poggiani (2012) é indicado quando ocorrem complicações secundárias e desconforto no animal.…”

“…O diagnóstico da papilomatose ocular definitivo deve ser feito através de exame histopatológico. A técnica de imuno-histoquímica também pode ser utilizada em casos de dificuldade para definir o diagnóstico (Vieira & Poggiani, 2012). No entanto, o mais comumente utilizado é o diagnóstico clínico, uma vez que as características das lesões são comuns à neoplasia.…”

“…O objetivo desse trabalho é relatar um caso de papilomavírus em conjuntiva bulbar da terceira pálpebra em um cão. Sabe-se que os papilomas podem apresentar diferentes regiões do corpo, sendo a apresentação ocular a menos frequente (Vieira & Poggiani, 2012). Papilomas na conjuntiva bulbar da terceira pálpebra em cães são pouco descritos na literatura, sendo esses, considerados raros e podem causar graves alterações oculares, podendo ocasionar comprometimento visual (Barros et al, 2008;Chacur et al, 2014).…”

Papilloma is a commonly benign neoplasm of viral etiology, with a cauliflower appearance, often found in canine species. It can present in the cutaneous, oral or ocular form, the latter being less common among animals. Clinical diagnosis is commonly used through its common morphological characteristics. However, the definitive diagnosis is made through histopathological and immunohistochemical examination. Most of the time, papilloma regress spontaneously, however, in some cases they are persistent and require treatment. The aim of this article is to report a clinical case of a dog with papillomavirus in the bulbar conjunctiva of the third eyelid. In this case, different treatment techniques were used, the combination of conjunctivectomy therapies, autohemotherapy and stimulation of the animal's immunity, culminated in a good patient response and up to six months of follow-up, there was no recurrence of the neoplasm in the dog.

“…Os papilomas são neoformações benignas provocadas pela infecção de um agente viral do gênero papilomavírus [26]. A regressão depende da imunocompetência do animal, a qual, neste caso, pode ter sido prejudicada pela presença de vários tipos tumorais e suas consequências clínicas.…”

Background: The prevalence of neoplasms in domestic animals has been augmenting over the years. Hemangiosarcoma, which most frequently affects large breed dogs, is a neoplasm with high metastatic power and corresponds to 5% of malignant neoplasms. Chemodectoma, a neoplasm that can have malignant or benign behavior, is uncommon, corresponding to less than 8% of all cardiac tumors, and originates from cardiac chemoreceptor cells and involves mainly the aortic and carotid bodies. The aim of this study is to describe the case of an elderly Pit Bull dog with hepatic hemangiosarcoma and chemodectoma associated with four other different tumors: hemangioma, papilloma, mastocitoma and melanoma.Case: A 14-year-old female Pit Bull, castrated, was presented to Veterinary Clinic of the Federal University of Santa Catarina (UFSC), Curitibanos Campus, Brazil. The owner referred apathy, hyporexia, and increased abdominal volume for two weeks. Physical examination showed emaciation and abdominal effusion. Abdominocentesis was performed, three liters of serosanguineous fluid was drained and a sample was sent for analysis. Complementary tests were requested and showed mild hypoalbuminemia, normocytic normochromic anemia, and lymphopenia. The ultrasound examination revealed thickening of vessels and hepatomegaly, in addition to the presence of an oval structure containing hyperechogenic cavitations. Diagnostic exploratory laparotomy was indicated, but the owner refused. Drug therapy was prescribed in a palliative manner and, during the clinical follow-up period, two abdominocentesis procedures and one thoracentesis procedure were performed, both resulting in simple transudate. Finally, the patient developed severe apathy, edema in all limbs, and died at home. Necroscopic examination was done and revealed hemoperitoneum and hemothorax; several nodules with diverse characteristics in the integument were noted, which were classified by histopathological analysis as follicular cyst, papilloma, cavernous hemangioma, mastocytoma, and melanoma. The histological sections of the liver sample showed hemangiosarcoma and those of the urinary bladder showed hemangiosarcoma metastases. In the heart, a nodule was found at the base of the aorta, which was characterized as chemodectoma. Besides that, there was myxomatous mitral valve degeneration. The necropsy report indicated that the cause of death was hypovolemic shock associated with complications from multiple tumors, particularly hepatic hemangiosarcoma and chemodectoma.Discussion: Hemangiosarcoma is a malignant tumor with invasive behavior. The patient was an elderly Pit Bull dog, a breed not described as being predisposed to this type of tumor. Similarly to other reports in the literature, there was abdominal effusion with rapid and recurrent evolution, progressive weight loss, and metastases in the urinary bladder. It is believed that thoracic effusion, limb edema, and hepatic venous congestion were probably caused by chemodectoma owing to right-sided congestive heart failure. Although not related to the cause of death of this patient, the presence of tumors like papilloma, mastocytoma, melanoma, and hemangioma is noteworthy because the canine had a total of six different types of neoplasms, rarely reported in Pit Bull dogs. This work emphasizes the importance of necroscopic evaluation, which, in this case, was essential for the definitive diagnosis.

“…O papiloma, conhecido como "verruga" (Figura 2), é uma neoplasia epitelial benigna que surge dos queratinócitos da epiderme e é frequentemente induzida por um papilomavírus espécie-específico (Dias et al, 2013;Fernandes et al, 2009;Vieira & Poggiani, 2012). O papiloma canino é uma doença infectocontagiosa viral de transmissão por contato direto e indireto, com um período de incubação de um a dois meses e, caso o animal apresente condições imunossupressoras, como para o vírus da imunodeficiência felina e medicamentos imunossupressores há a ativação ou reativação da atividade viral.…”

As neoplasias ocorrem pelo acúmulo progressivo de mutações no genoma celular que resultam em perda do controle de crescimento, diferenciação e morte celular. As neoplasias cutâneas têm um papel epidemiológico importante dentro da oncologia veterinária, pois a pele é o maior órgão do corpo e está em constante exposição a riscos e fatores oncogênicos, que associados podem favorecer o desenvolvimento de neoplasias. Neste sentido, objetivou-se realizar uma revisão de literatura acerca das principais neoplasias cutâneas na clínica de pequenos animais, facilitando assim o diagnóstico, o prognostico e até mesmo a qualidade de vida dos pacientes portadores das mesmas.
