| Osteosarcoma is defined as a bone matrix-producing malignant mesenchymal tumor. It is relatively rare among domestic animals, but corresponds to 85% of all malignant bone tumors in dogs. To study canine osteosarcoma in animals living in Brazil and correlate the clinical-morphological findings with prognosis, forty-six cases of dogs with osteosarcoma were studied retrospectively out of a total of 56 malignant primary bone tumors on file. The animals were assessed in terms of age, sex, breed, topographic tumor distribution, and presence of metastases at diagnosis. The tumors were classified histologically by the method of Pool¹. Osteosarcomas corresponded to 82% of primary malignant bone dysplasias in the sample studied. Age ranged from 6 months to 14 years... |

| Dermatophytosis is a zoonosis in whose etiology the dermatophyte Microsporum canis is frequently involved. The fungus can be transmitted to man by dogs and cats. In the present study, guinea pigs were experimentally inoculated with M. canis and the course of the lesions was evaluated. Inoculation resulted in lesions in 100% of the animals, with a clinical course consisting of an incubation period, an inflammatory and a phase of lesion resolution. The histopathologic evaluation of the skin biopsies revealed the presence of acanthosis, hyperkeratosis, spongiosis and marked dermal edema. M. canis spores and hyphae were detected in histologic sections stained with periodic acid-Schiff. The combination of the fluorescent dyes FD and EB permitted the adequate... |
