Adult Wilms' tumor--a case report
Yonsei Medical Journal
|January 1, 1989
Summary
This case report details an extremely rare instance of Wilms' tumor in a 67-year-old female, presenting with extensive local invasion and widespread bone metastases. The findings highlight the aggressive nature and unusual presentation of this pediatric cancer in an adult patient.
Area of Science:
- Nephrology
- Oncology
- Pathology
Background:
- Wilms' tumor is a rare kidney cancer typically diagnosed in young children.
- Adult Wilms' tumor is exceptionally uncommon, with limited data on its presentation and behavior.
Observation:
- A 67-year-old female presented with a large left kidney mass.
- The tumor extensively infiltrated surrounding structures, including Gerota's fascia, adrenal gland, and ureter, with renal vein thrombus.
- Multiple bone metastases were identified in the skull, shoulder, rib, pelvis, and femur.
Findings:
- Microscopic examination revealed predominantly blastemal Wilms' tumor with anaplasia.
- Areas of tubular differentiation and chondroid elements were present.
- Clear cell nests with downward maturation were observed in the proximal ureter.
Implications:
- This case underscores the possibility of Wilms' tumor occurring in older adults, challenging typical age-related diagnostic assumptions.
- The advanced local invasion and metastatic spread emphasize the aggressive potential of adult Wilms' tumor.
- Further research into the molecular mechanisms and optimal treatment strategies for adult Wilms' tumor is warranted.
