Cryptococcal lymphadenitis in a dog

Abstract

We describe a case of canine crytococcocosis, 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 μm 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 necropsia we take samples for their microbiology and histopathology study, both techniques detect to C. neoformans in marrow, SNC tissue and lymp nodes.
