Description
The specimen is a transsected left kidney. The upper pole is expanded by an irregular tumour mass.
This is lobulated and contains extensive areas of cystic degeneration. The tumour is invested by a
pseudo capsule and does not appear to infiltrate the middle and lower poles of the kidney.
Histologically the tumour was shown to be a nephro-blastoma (Wilms' Tumour).
History
The patient was a 4 year old female who was noted by her mother to have an abdominal
mass which was treated by pre-operative chemotherapy and nephrectomy. The patient made an
uneventful recovery. She has been followed for four years and remains free of tumour recurrence.
