Renal tumors were found in two cottontail rabbits (Sylvilagus floridanus) about 1 year old. One tumor was intimately associated with the kidney and consisted of isolated ductular and tubular structures within an abundant connective tissue stroma and was diagnosed as a hamartoma of urogenital origin. The second was composed of epithelial cells arrange as alveolar structures with papillary projections, epithelium that was less differentiated into tubules and ducts, and neoplastic epithelial cells in solid sheets. The diagnosis of renal adenocarcinoma was based on the histologic features as metastasis had not occurred.
在两只约1岁的棉尾兔（佛罗里达棉尾兔）身上发现了肾肿瘤。一个肿瘤与肾脏紧密相连，由丰富结缔组织基质内的孤立导管和管状结构组成，被诊断为泌尿生殖系统起源的错构瘤。另一个由排列成肺泡状结构并带有乳头样突起的上皮细胞、分化程度较低的小管和导管上皮以及实性片状的肿瘤上皮细胞组成。肾腺癌的诊断基于组织学特征，因为尚未发生转移。
