ABSTRACT: Cryptococcus gattii is often associated with pulmonary and systemic infections in humans and animals. In this research we report a case of nasopharyngeal cryptococoma caused by C. gatti in an equine. A 10-year-old mare presented a mass obstructing the oropharynx. Macroscopically the mass was asymmetric, and was attached to the ethmoidal sinuses and obstructed the oropharynx. Histopathological examination of the mass revealed multiple yeast cells ranging from spherical to oval, 4-8μm in diameter, with some of them showing narrow base polar budding. Cryptococcus gattii growth in mycological culture (Sabouraud Dextrose Agar) and was L-canavanine-glycine-bromothymol blue Agar positive. The molecular identification confirmed the isolate as C. gattii...

ABSTRACT: Osteochondromas are primary bone tumors characterized by cartilage-covered bone projections involving single or multiple masses (osteochondromatosis). This study reports the clinical and pathological findings from a young domestic cat with osteochondroma in the humerus. During the clinical evaluation, the animal had pronounced right forelimb musculature atrophy and an increased distal humeral volume. Histopathological examination of the neoplasm revealed a proliferative lesion characterized mostly by endochondral ossification and peripheral foci of proliferating cartilage tissue. Further testing using immunohistochemical staining and polymerase chain reaction revealed the presence of feline leukemia virus antigens in the hematopoietic cells of...
