Wilms' tumor with metastasis to duodenum - the first reported case in Thailand.

ABSTRACT

A case of Wilms' tumor with gastrointestinal tract metastasis of the duodenum was documented in a 22 month - old - child. She had been diagnosed with Wilms' tumor stage III, treated surgically and by radiation and chemotherapy about 1 year previously. While she was still on chemotherapy, she developed hematemesis and clinical signs of partial gut obstruction. Gastroscopy and upper gastrointestinal series showed an intraluminal vascular mass in the duodenal bulb and histologically proved to be Wilms' tumor. We believe this is the first report in the world of Wilms' tumor with gastrointestinal tract metastasis.
