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.

这是一个猫科动物的病例报告，该动物颈部出现皮肤感染，从中分离和鉴定了新型隐球菌（以前的C. neoformans var. grubii ）。猫出现两个结节性肿瘤，直径约2厘米，凸起，实性，表面略显不规则，呈淡红色，有白色区域。组织学上，这些肿瘤对应于肉芽肿性皮炎和脂膜炎，病灶内存在大量酵母菌。通过这些病变样本的生化和光谱技术鉴定，确定病原体是C.neoformans。关于这种隐球菌的信息很少在不涉及其他器官的情况下引起皮下感染，并且在少数可用报告中这种病原体的存在尚未得到可靠确定。这是哥斯达黎加首次报道一只猫受到C. neoformans的影响。
