Image Description

The stromal component of Wilms tumor is usually fibroblastic or myxoid and may contain heterologous elements such as skeletal muscle, smooth muscle, bone, cartilage, adipose tissue (shown here), and neuroglial tissue. Some cases with an abundance of heterologous elements begin to resemble teratomas and are sometimes referred to as teratoid Wilms tumor.
