This is a case report of a feline animal that presented with a skin infection on the neck from which Cryptococcus neoformans (former C. neoformans var. grubii) was isolated and identified. The cat presented two nodular tumors, approximately 2 cm in diameter, raised, solid, with a slightly irregular surface and a reddish color with white areas. Histologically, these tumors corresponded to granulomatous dermatitis and panniculitis with the presence of a large number of intralesional yeasts. From identification with biochemical and spectroscopic techniques of these lesion samples, it was determined that the etiological agent was C. neoformans. There is little information on this variety of Cryptococcus causing subcutaneous infection without involvement of other organs, and the presence of this pathogen in the few reports available has not been reliably determined. This is the first report of a cat affected by C. neoformans in Costa Rica.
