[Cryptococcal lymphadenitis in a dog.]

We describe a case of canine crytococcosis, the clinical symptoms were: feverish syndrome, vomiting and diarrhoeas and bilateral lymphadenitis in superficial lymph nodes. Microbiology and histopathology study of popliteal lymph node biopsy demonstrated the presence of round yeasts of some 3 microm of diameter, which we identified as Cryptococcus neoformans. Thirty months after suspending the medication the dog returned to the surgery; the dog was very thin and it had nervous symptoms; the owners decided it upon euthanasia. After carrying out the necropsy we take samples for their microbiology and histopathology study, both techniques detect to C. neoformans in marrow, CNS tissue and lymph nodes.
