kidney neoplasms/arachis hypogaea

A fatal collecting duct carcinoma, presenting with pleural metastases, arose from the right kidney in an 8-year-old child. A distal nephron origin of the tumor is supported by positive tumor staining with Ulex europaeus and Arachis hypogaea, and a lack of staining with Tetragonolobus lotus. The

Many renal diseases involving the tubular epithelium appear to preferentially affect certain nephron segments. While major portions of the nephron, such as proximal and distal convoluted tubules and collecting ducts, can be identified in the normal kidney, the distinction of diseased nephron

To distinguish common epithelial tumors arising in the kidney may have significant implications, in terms of molecular ontogeny and prognosis. It is important to investigate the distribution of immunoexpression of commonly used markers among renal neoplasms and to develop a useful panel as an
