Considerations about ocular neoplasia of dogs and cats

Abstract

Primary and secondary neoplasia of dogs and

Neoplasmas oculares e de anexos em cães e gatos no Rio Grande do Sul: 265 casos (2009 -2014)

“…Os neoplasmas oculares podem ser classificados em primários e secundários sendo que os primários são frequentes em cães e gatos (Wilcock 2007b), e normalmente exibem um baixo potencial metastático (Conceição et al 2010). Esses tumores são uma causa comum de enucleação em gatos (Dubielzig 2011) e a segunda maior causa de enucleação em cães (Wilcock, 2007a).…”

“…Além disso, inflamação e glaucoma secundário podem surgir a partir de neoplasias e causar um dano severo ao olho (Conceição et al 2010). Esse trabalho tem por objetivo identificar e analisar a ocorrência das neoplasias oculares e dos seus anexos em cães e gatos através do estudo retrospectivo de amostras enviadas ao Setor de Patologia Veterinária (SPV) da Universidade Federal do Rio Grande do Sul (UFRGS) no período de janeiro de 2009 a dezembro de 2014.…”

Eye-related neoplasms in dogs: A retrospective study

“…(2013) analyzed a considerable number of ocular neoplasms (n = 173) finding numerous cases in dogs over 10 (43.2%) and 6-10 years (40.6%), and few cases in those under 5 years of age (9.9%). Several studies have evaluated ocular neoplasms, observing an age predilection, mainly in dogs between 8 and 11 years of age (Abarca et al ., 2002;Heath et al ., Eye neoplasms in dogs 2003;Laus et al ., 2008;Conceição et al ., 2010;Fernandez, 2013;Werner et al ., 2017). These reports are in agreement with our findings, where the age group with the highest incidence (8-11 years of age) presented significant difference when compared to the other age groups.…”

“…These reports are in agreement with our findings, where the age group with the highest incidence (8-11 years of age) presented significant difference when compared to the other age groups. Even though histiocytoma is common in young dogs (with an average age of 3 years; Conceição et al ., 2010;Fernandez, 2013) the age range in the present study was 2-8 years. Fernandez (2013) reported a distribution of ocular neoplasms by sex, with a higher presentation in male dogs (56.2%) compared to females (43.8%).…”

“…(2016) who reported that mixed-breed (26.6%), Labrador retriever (16.1%) and Poodle (11.2%) were the breeds most commonly affected by ocular neoplasms. Other researchers reported that Labrador retriever and Poodle breeds are predisposed to ocular neoplasms -mostly adenomas, adenocarcinomas, and melanomas (Conceição et al ., 2010;Fernandez, 2013;Dees et al ., 2015).…”
