Congenital mesoblastic nephroma is a type of kidney tumor that is usually found before birth by ultrasound or within the first 3 months of life. It contains fibroblastic cells (connective tissue cells), and may spread to the other kidney or to nearby tissue. Congenital mesoblastic nephroma is more common in males.
A common differential diagnosis includes the following tumors:
- Mesoblastic nephroma (congenital): from birth to 1 year
- Rhabdoid tumor: from 1 to 2 years of age
- Clear cell sarcoma of the kidney: from 2 to 3 years of age.
- Wilm's tumor: over 3 years of age.
The age breakdown is far from exact, but provides a useful age range and approximate order. Wilm's is most common, accounting for 80-85% of all pediatric kidney tumors. Congenital mesoblastic nephroma accounts for about 10-15%; rhabdoid and CCSK split the remained 5-10%.
