What is the histologic name for Wilms tumor?

Wilms tumor, also known as nephroblastoma, is a specific type of kidney cancer that primarily occurs in children. It is characterized histologically by the presence of immature kidney cells and can be recognized by its unique combination of blastemal (embryonic), epithelial, and stromal components. The term nephroblastoma reflects its origin from nephrogenic (kidney-forming) tissues during embryonic development. This tumor is typically diagnosed in children aged 3 to 4 years and is the most common form of kidney cancer in this age group.

The other terms presented are associated with different conditions or tumors, and therefore do not apply to Wilms tumor. Neuroblastoma refers to a cancer that develops from immature nerve cells in various areas of the body, primarily affecting infants and young children. Blastomycosis is a fungal infection caused by the Blastomyces dermatitidis organism, unrelated to tumors. Glioblastoma is a highly aggressive brain tumor derived from glial cells in the central nervous system. Thus, nephroblastoma is the correct histologic name specifically associated with Wilms tumor.
