Squamous Predominant Teratoid Wilms’ Tumor

Teratoid Wilms Tumor: Report of Three Cases and Review of the Literature.

Teratoid Wilms tumor is a rare variant of Wilms tumor composed predominantly of well-differentiated epithelial and/or mesenchymal heterologous elements. Like the classical Wilms tumor, this variant may also occur as a renal mass or may be found in extra renal locations. This tumor may be treated effectively by surgical resection; however, it generally fails to respond to chemotherapy. A review ...

Familial synchronous bilateral teratoid Wilms tumor with elevated alpha-fetoprotein level.

Familial Wilms tumor is a rare entity that accounts for only 1-2% of all Wilms tumor cases, with an earlier age of onset and an increased frequency of bilateral tumors. Teratoid Wilms tumor is a variant of nephroblastoma with a predominance of heterologous tissues comprising more than 50% of the tumor volume. Wilms tumor does not usually secrete any specific tumor marker and all teratoid Wilms ...

MiR-21 Expression in Wilms’ Tumor

Background and Objective: Wilms’ tumor (WT) is the most common genitourinary tract tumor in children. MicroRNAs (miRNAs) are small non-coding RNAs; their role in the pathogenesis of many types of human cancers has been identified. We aimed to evaluate the expression of miR-21, a well-known oncomir, in WT tissue samples which is a very common urinary tract malignancy in children...

Wilms Tumor

[Wilms' tumor].

Today the prognosis in children with nephroblastoma is excellent. With the combination of surgery, chemotherapy and radiation more than 80% of children can be cured. Because of acute toxicity and late effects of treatment (scoliosis, cardiotoxicity, fertility problems and second malignancies) a major issue in the management of children with this kind of malignancy is the reduction of chemothera...
