Teratoid Wilms tumor is an unusual histological variant of nephroblastoma with predominant heterologous component. Frequently present components include adipose tissue, glial tissue, muscle, cartilage or bone. The presence of squamous epithelial component on the other hand is rarely reported. We describe a case of unilateral teratoid Wilms' tumor in a 2-year-old boy with lung metastasis. In this case, tumor showed the familiar triphasic histologic pattern of nephroblastoma along with extensive squamous epithelial component.
畸胎样肾母细胞瘤是肾母细胞瘤一种不常见的组织学变异型，以异源性成分占主导。常见的成分包括脂肪组织、神经胶质组织、肌肉、软骨或骨。另一方面，鳞状上皮成分的存在很少被报道。我们描述了一例2岁男孩单侧畸胎样肾母细胞瘤伴肺转移的病例。在该病例中，肿瘤呈现出肾母细胞瘤常见的三相组织学模式以及广泛的鳞状上皮成分。
