Congenital mesoblastic nephroma is a relatively rare infantile renal tumor. It comprises 3-6% of renal masses in childhood and 50% during the neonatal period. Most mesoblastic nephroma occur in the newborn period, with 80% of the cases being reported within the first month of life. Macroscopically the tumor is composed of a solid mass of different sizes tending to invade the surrounding structures and renal parenchyma. The authors report a case of cystic mesoblastic nephroma of the cellular subtype, with diffuse areas of hemorrhage and necrosis. The tumor was treated by surgical excision with radical nephrectomy and the child is doing well 4 years after the operation.
先天性中胚层肾瘤是一种相对罕见的婴幼儿肾肿瘤。它占儿童肾肿块的3% - 6%，在新生儿期占50%。大多数中胚层肾瘤发生在新生儿期，80%的病例在出生后第一个月内被报道。宏观上，肿瘤由不同大小的实性肿块组成，倾向于侵犯周围结构和肾实质。作者报告了一例细胞亚型的囊性中胚层肾瘤，伴有弥漫性出血和坏死区域。该肿瘤通过根治性肾切除术进行手术切除，术后4年患儿情况良好。
