    Scientific investigations on the mammals of Angola started over 150 years ago, but information remains scarce and scattered, with only one recent published account. Here we provide a synthesis of the mammals of Angola based on a thorough survey of primary and grey literature, as well as recent unpublished records. We present a short history of mammal research, and provide brief information on each species known to occur in the country. Particular attention is given to endemic and near endemic species. We also provide a zoogeographic outline and information on the conservation of Angolan mammals. We found confirmed records for 291 native species, most of which from the orders Rodentia (85), Chiroptera (73), Carnivora (39), and Cetartiodactyla (33). There is a large number of endemic and near endemic species, most of which are rodents or bats. The large diversity of species is favoured by the wide range of habitats with contrasting environmental conditions, while endemism tends to be associated with unique physiographic settings such as the Angolan Escarpment. The mammal fauna of Angola includes 2 Critically Endangered, 2 Endangered, 11 Vulnerable, and 14 Near-Threatened species at the global scale. There are also 12 data deficient species, most of which are endemics or near endemics to the countryinfo:eu-repo/semantics/publishedVersio

    O conceito de dermatoses neutrofĂ­licas engloba diversas entidades que partilham aspetos clĂ­nicos e histolĂłgicos. Recentemente descrita, a dermatose neutrofĂ­lica do dorso das mĂŁos Ă© uma patologia com etiologia desconhecida que se assemelha, clinicamente, a uma variante localizada da SĂ­ndrome de Sweet com lesĂ”es predominantemente localizadas no dorso das mĂŁos e com presença variĂĄvel de sintomas gerais acompanhantes. Do ponto de vista histolĂłgico Ă© caracterizada por um denso infiltrado inflamatĂłrio neutrofĂ­lico, sendo variĂĄvel a existĂȘncia de achados de vasculite. Os autores apresentam dois doentes com dermatose neutrofĂ­lica do dorso das mĂŁos e discutem os aspetos clĂ­nicos, laboratoriais, histopatolĂłgicos e a as opçÔes terapĂȘuticas desta entidade. A dermatose neutrofĂ­lica do dorso das mĂŁos Ă© um conceito em evolução, que partilha diversos aspetos comuns com outras dermatoses neutrofĂ­licas, sugerindo um espetro continuo deste grupo de doenças
