Wilms Tumor (Nephroblastoma) : Post-Chemotherapy

Comments:
Ruptured nephroblastoma following chemotherapy. The tumor was 90% necrotic post-chemotherapy. The patient was a 7 y/o male. Given the tumor spillage into the peritoneal cavity, this would be classified as Stage III (National Wilms Tumor Study). Image copyright: pathorama.ch.
