RESUMO
Background: Otitis is a severe inflammation of the skin of the auditory canal which can impact animals of all ages. Insheep, this disease can occur in isolated cases or in the entire flock. Laser photobiomodulation can be used in combination with medication or as single therapy and the effects are analgesia, modulation of the inflammatory process, edemareduction, tissue restoration and stimulation of local microcirculation. Antimicrobial photodynamic therapy stands out asa promising alternative to antimicrobial drugs for the treatment of localized infections. This study aimed to report the useof laser phototherapies on a sheep with bacterial otitis.Case: A case of bacterial otitis in a 4-year-old sheep, Dorper, was treated at the Veterinary Hospital of the State Universityof Santa Cruz. In the anamnesis, the owner reported that the patient presented crusts in the auricular pavilions, and hadbeen medicated with oxytetracycline 20%, administered intramuscularly, for two days and the crusts cleaned with iodine10%, but the animal did not present clinical improvement. On physical examination, the animal presented constant headswaying, edema of the ears, otalgia, enlarged parotid lymph nodes and ear wounds. No ear discharge was observed, andthe initial diagnosis was aural hematoma. The treatment prescribed was laser photobiomodulation for three consecutivedays. The lesions were irradiated with a diode laser with a power of 0.1 W, irradiance of 3.5 W/cm2, continuous emission,spot area of 0.028 cm2, wavelength of 808 nm, energy of 4J/point, and fluency/point of 142.8J/cm2, with seven pointson the external surface and four points on the internal surface of both ears. Two points were also targeted on the parotidlymph nodes with infrared laser (λ = 808 nm), with energy of 2J/point. On the fourth day of hospitalization, there was areduction in lesions, decreased edema and absence of pain and on the sixth day...(AU)

Contexto: Descrição de neoplasia maligna cutânea com expressão clínica rara. Descrição do caso: Paciente do sexo feminino, de 41 anos, apresentou-se com placa endurada, acastanhada, infiltrada, de superfície irregular e crescimento progressivo, localizada na face lateral do braçodireito (terço proximal) há quatro anos. À dermatoscopia, tinha rede pigmentar periférica, vasos arboriformes focados e desfocados, crisálidas,coloração rosa de fundo e áreas despigmentadas sem estruturas. Foram elencadas as hipóteses de carcinoma basocelular, dermatofibroma edermatofibrossarcoma protuberans. Biópsia incisional evidenciou neoplasia fusocelular na derme e infiltração do tecido subcutâneo em ?favode mel?. A imunoistoquímica revelou expressão de CD34 nas células neoplásicas. Com esses elementos, foi realizado diagnóstico de dermatofibrossarcoma protuberans. Discussão: O dermatofibrossarcoma protuberans, tumor fibro-histiocítico de malignidade intermediária, é o sarcoma cutâneo mais frequente. O pico de incidência ocorre entre 30 e 40 anos, sendo o tronco o principal local de acometimento. Surge comoplaca endurada, assintomática, aderida à pele, de cor rósea a violácea, com 1 a 5 cm de diâmetro. Após meses até décadas, passa a apresentarmúltiplos nódulos na superfície. Em casos avançados/recorrentes, pode invadir fáscia, músculo e osso. A dermatoscopia é promissora comoauxiliar no diagnóstico precoce desse tumor. Confirmação diagnóstica é estabelecida por meio da associação dos dados clínicos, dermatoscópicose principalmente pela análise histopatológica/imunoistoquímica do tumor. Tratamento clássico é cirúrgico com margens amplas, porém não há consenso estabelecido a respeito de seu tamanho. Apresenta elevadas taxas de recidiva local e metástases são raras. Conclusões: Relata-se tumor maligno raro, cujo diagnóstico precoce aumenta as chances de sucesso terapêutico.
