A mass made up of 2 distinct synchronous primary malignant tumors is a rare event in adults, and exceedingly so in children. Such lesions have been called collision tumors. Reported here is an infant who was found to have a collision tumor comprised of a neuroblastoma and a congenital mesoblastic nephroma, in contiguity, in the right kidney. This is the first report of a collision tumor in an infant. This also is the first report of a synchronous occurrence of a neuroblastoma and a congenital mesoblastic nephroma. The authors present this case and discuss the available literature.
由两种不同的同步原发性恶性肿瘤组成的肿块在成人中是罕见事件，在儿童中更是如此。此类病变被称为碰撞瘤。本文报告了一名婴儿，其右肾发现有一个由神经母细胞瘤和先天性中胚层肾瘤相邻组成的碰撞瘤。这是婴儿碰撞瘤的首例报告。这也是神经母细胞瘤与先天性中胚层肾瘤同步发生的首例报告。作者展示此病例并讨论现有文献。
