The Ehlers-Danlos syndrome (EDS) consists of a group of diseases characterized by defective collagen production or failure in its organization, resulting in changes in the strength and extensibility of connective tissue. This report describes the dermatological and histological findings observed in a 3-month-old crossbreed cat with rupture and detachment of skin in the thoracic limb and rupture of the skin in the cervical region. Upon dermatological examination, the cat presented fragile and hyperextensible skin in the cervical region and a skin extensibility index of 21%. Histopathological evaluation of the skin specimens revealed evident disorganization of collagen bundles in dermis and in the Masson's trichrome staining, follicular dysplasia was found. The presumptive diagnosis of EDS was made based on the clinical and histopathological findings. Sanger sequencing did not detect any mutated alleles for the c.3420delG mutation in COL5A1 gene, which was an autosomal dominant mutation previously been associated with Ehlers-Danlos syndrome in cats. The absence of this mutation in the reported cat suggests that other mutation may also be responsible for the development of cutaneous asthenia in this or maybe other genes related to collagen metabolism.

The present study aims to identify dermatological alterations due to the work carried out by women on dairy farms and presents an intervention process on dermatology health with women working in these locations. It is a quasi-experimental study, in an intervention form, in which each subject is independent. It was performed with 20 women working on a dairy farm in Rio Grande, Rio Grande do Sul, Brazil, between July and October 2011. Most (60%) women identified dermatological changes due to the work. During the intervention, dermatological care action was focused on. The knowledge of these results offers valuable information for those who teach and advice people about dermatological care in rural working places, where such rates of occurrence are high.

A ceratose liquenóide é uma rara dermatopatia proliferativa descrita em humanos e cães. Nos cães, a doença caracteriza-se pelo aparecimento de placas hiperceratóticas bem circunscritas nas pinas e, menos freqüentemente, nas virilhas. Este artigo descreve um caso de ceratose liquenóide em um cão macho, Dobermann, de seis anos de idade, com lesões verrucosas e multifocais na face interna das orelhas e lesões alopécicas, hiperpigmentadas, levemente elevadas e descamativas nas axilas e virilhas, ambas com evolução de aproximadamente três meses. O diagnóstico foi realizado com base na associação entre os achados clínicos e histopatológicos.Lichenoid keratosis is a rare proliferative dermatopathy reported in human beings and dogs. In dogs the disease is characterized by well circumscribed hyperkeratotic plaques distributed in the skin of pinnae and, less frequently, in the inguinal region. This report describes a case of lichenoid keratosis in a six-year-old male Dobermann dog which had multifocal verrucous lesions in the internal aspect of the pinnae and slightly scaly, overpigmented alopecic lesions in the axillae and inguinal region; both lesions had a clinical course of approximately three months. The diagnosis was based on the association of the clinical and histopathological findings.

Os arquivos de biópsias de cães realizadas no Laboratório de Patologia Veterinária da Universidade Federal de Santa Maria entre 1964 e 2003 foram revisados à procura de tumores cutâneos. Dos 703 registros encontrados, em 570 (81,0%) estava descrito que o cão apresentava apenas um tumor na pele e, em 133 (19,0%), que o cão apresentava mais de um tumor. Seiscentos e cinqüenta e quatro (93,1%) cães apresentavam apenas um tipo histológico de tumor e 41 (5,8%) apresentavam dois tumores histologicamente distintos. Em sete (1,0%) cães, havia três tumores diferentes e em um (0,1%) cão foram diagnosticados quatro tumores não relacionados, finalizando um total de 761 tumores. Dos 761 tumores cutâneos encontrados, 673 (88,4%) eram neoplásicos e 88 (11,6%) eram não-neoplásicos. Os 15 tumores mais prevalentes em ordem decrescente de freqüência foram: mastocitoma, carcinoma de células escamosas, adenoma perianal, lipoma, tricoblastoma, carcinoma perianal, papiloma, cistos foliculares, hemangioma, hemangiossarcoma, melanoma, adenoma sebáceo, histiocitoma, hiperplasia sebácea nodular e fibroma.

Descrevem-se as lesões cutâneas macroscópicas em 10 e histológicas em 8 vacas afetadas por doença granulomatosa sistêmica associada ao pastoreio de ervilhaca (Vicia spp.). Em todos os casos, as lesões cutâneas eram caracterizadas por múltiplas áreas coalescentes de alopecia, liquenificação e descamação. Os locais mais atingidos pela lesão de pele foram: cabeça e pescoço (10/10), tronco (4/10), períneo (3/10) e mama (2/10). Em todos os 8 casos avaliados histologicamente, as lesões se caracterizavam por dermatite perivascular superficial granulomatosa de intensidade variável. Outros achados histológicos incluíram dermatite perivascular profunda (1/8), perifoliculite (2/8), foliculite mural (3/8), hiperqueratose ortoqueratótica compacta (6/8), erosões (1/8), úlceras (2/8), microabscessos de Munro (8/8), crostas serocelulares (1/8), espongiose (4/8), degeneração hidrópica (5/8), acantólise (1/8), corpúsculos de Civatte (2/8), exocitose linfoplasmocitária (6/8), edema superficial (6/8), incontinência pigmentar (2/8), basofilia (6/8) e mineralização distrófica do colágeno (2/8), tumefação do núcleo das células endoteliais (8/8) e ectasia de glândulas sudoríparas (8/8).

Alterações adquiridas na coloração da pelagem de cães são raras. Schnauzers miniaturas podem apresentar desenvolvimento idiopático de coloração dourada do pelame, primariamente do tronco, chamada de aurotriquia. O presente trabalho relata a ocorrência de aurotriquia em um cão da raça schnauzer, de três anos de idade, sendo esse o primeiro relato de caso de aurotriquia em schnauzer no Brasil. Por se tratar de alteração de rara ocorrência, torna-se necessária maior atenção a características raciais e um melhor exame físico e anamnese, mesmo se tratando de alteração considerada meramente de fenótipo, pois existem as alterações de coloração bem piores, ligadas a doenças de prognóstico.Coat color changes in adult dogs are rare. Miniature schnauzers can development golden hair coat color, primarily in the trunk, called aurotriquia. This paper reports the occurrence of aurotriquia in a schnauzer, three years old, being this the first case report of aurotriquia schnauzer in Brazil. Due to its rare occurrence there is a need for greater attention to racial characteristics and a better physical examination and medical history, Despite, being only a change in the phenotype, there are color changes related to worse disease prognosis.

Relata-se o caso de um canino, Poodle, fêmea de 12 anos, apresentando poliúria, polidipsia, polifagia, alopecia progressiva e cegueira. Ao exame clínico, observou-se caquexia, alopecia simétrica bilateral em tronco, dorso, membros e abdômen, pele hiperpigmentada, adelgaçada e hipotônica, associados à seborréia, ceratoconjuntivite seca, piodermite interdigital e catarata bilateral. Na avaliação laboratorial, constatou-se hiperglicemia, glicosúria e anemia, configurando-se inicialmente um quadro de diabetes mellitus. Para investigação de um provável hiperadrenocorticismo como doença primária, foi realizada a avaliação da função da adrenal, utilizando-se o teste de supressão com dexametasona na dose de 0,01mg/kg/IV, cujos resultados (basal=3,4mig/dl e 8 horas após dexametasona = 1,5mig/dl) mostraram-se normais. Após instituição da terapia com insulina observou-se diminuição da poliúria/polidipsia, aumento de peso corpóreo e total recobertura pilosa após três meses de tratamento. Conclui-se que o quadro dermatológico foi decorrente das alterações metabólicas relacionadas à deficiência de insulina, fato este raro segundo a bibliografia compilada.A 12 year-old female toy Poodle was presented with polyria, polydipsia, polyphagya, progressive alopecia and blindness. The animal was cachetic, with simmetric bilateral alopecia of the torso, abdomen and limbs. The skin was hyperpigmented, thin and hypotonic with seborhea and interdigital pioderma. The dog also had keratoconjuntivitis sicca and bilateral cataracts. Hyperglicemia, glicosuria and anemia were confirmed by laboratory exams and a working diagnosis of Diabetes meilitus was established. A low-dose dexamethasone (0,01mg/kg/IV) supression test was performed to rule out hyperadrenocorticism and was normal (basal value = 3.4mu/dl and 8 hours post-dexamethasone = 1.5,mug/dl). Insulin therapy was initiated and resulted in remission of all clinical signs, with body weight recovery, polyuria and polydipsia resolution and complete hair coat regrowth within 3 months. We concluded that the dermatosis in this case was associated to metabolic alteration related to insulin deficiency.

Descreve-se um surto de dermatite alérgica sazonal em ovinos nos municípios de São Vicente do Sul e Jaguari, Rio Grande do Sul. Os ovinos afetados não tinham raça definida e pertenciam a diversas categorias. As lesões eram vistas principalmente na cabeça (orelhas e ao redor dos olhos, focinho e lábios), úbere, porção distal dos membros e abdômen ventral. Dois padrões de lesão foram encontrados; num padrão agudo havia acentuado eritema associado à grande quantidade de pápulas, pústulas, colaretes epidérmicos e crostas; no padrão crônico, áreas liquenificadas, ulceradas, exsudativas, crostosas, alopécicas e, por vezes, sangrantes, eram vistas nos mesmos locais. Microscopicamente, os ovinos mais recentemente afetados demonstravam dermatite perivascular superficial eosinofílica, já os animais com lesões mais antigas apresentavam dermatite perivascular superficial linfo-histioplasmocitária.

This paper described a case of a capuchin monkey (Sapajus libidinosus) with non-pruritic skin lesions. During the physical examination, multifocal areas of alopecia with crusts, erythema and scaling compatible with dermatophytosis were reported on the right fore and hind limbs and on tail. Fungal culture findings revealed a diagnosis of dermatophytosis due to Microsporum canis. The animal was successfully treated with itraconazole. This is the first report of a dermatophytosis case in S. libidinosus and the first description of an effective treatment in this species. [ABSTRACT FROM AUTHOR]
