Despite Wilms tumor 1 (WT1)protein was originally considered as a specific immunomarker of Wilms tumor, with the increasing use of immunohistochemistry, there is evidence that other tumors may share WT1 protein expression. This review focuses on the immunohistochemical profile of WT1 protein in the most common malignant tumors of children and adolescents. The variable expression and distribution patterns (nuclear vs cytoplasmic) in the different tumors, dependent on the antibodies used (anti-C or N-terminus WT1 protein), will be emphasized by providing explicative illustrations. Potential diagnostic pitfalls from unexpected WT1 protein expression in some tumors will be discussed in order to avoid diagnostic errors, especially when dealing with small biopsies.
