Cryptococcosis is a mycosis caused by yeasts of genus Cryptococcus, mainly the species C. neoformans and C. gattii that can affect humans and animals. These yeasts are widely distributed in the environment and are typically associated with avian droppings and decaying wood. Most infections are related to the respiratory tract, but the central nervous system and cutaneous lesions are also reported in the literature. The present report is a case of cryptococcosis in an 18-month-old unspayed female English Bulldog with the main complaint of weight loss and diarrhea. The presence of two large masses observed in an ultrasound examination leads us to perform an exploratory laparotomy. Considering the size of the lesion and the impossibility of owner to provide intensive care, the consent for euthanasia was requested. The postmortem diagnosis of cryptococcosis was revealed by cytological evaluation, and the involvement of C. gattii VGII was confirmed by isolation and identification tests as well as by the detection of the URA5 gene restriction fragment length polymorphism PCR analysis. Reports in the literature of the involvement of Cryptococcus in gastrointestinal lesions are rare in both human and veterinary medicine. Data about different forms of cryptococcosis are important to provide more knowledge of uncommon clinical presentations of this yeast and therefore improve the diagnoses and decisions for the best therapy.
