CD10 immunohistochemical staining in urothelial neoplasms.
CD10, or common acute lymphoblastic leukemia antigen, is a cell surface neutral endopeptidase that inactivates various bioactive peptides. It is expressed by hematopoietic cells and their neoplasms and in a variety of nonhematopoietic tissues and neoplasms. CD10 has been suggested as a useful marker for urothelial carcinoma, but the few studies of CD10 in urothelial tissues have shown varying r...
متن کاملImmunohistochemical Differentiation between Urothelial Papillomas and Papillary Neoplasms of Low Malignant Potential of the Urinary Bladder.
BACKGROUND Urothelial papilloma and non-invasive papillary carcinoma are common neoplasms of the urinary bladder. Distinguishing papillomas and papillary carcinomas, especially the low grade type, is often debatable on the basis of histological features alone. MATERIALS AND METHODS We investigated immunohistochemical expression of cytokeratin 20 (CK20), p53, and Ki-67 in a group of 20 urothel...
متن کاملUrothelial Bladder Cancer Urinary Biomarkers
Urothelial bladder cancer is the fourth most prevalent male malignancy in the United States and also one of the ten most lethal. Superficial or non-muscle-invasive bladder cancer has a high rate of recurrence and can progress to muscle invasive disease. Conventional surveillance requires regular cystoscopy and is used often with urinary cytology. Unfortunately, the cystoscopy procedure is invas...

متن کاملUrothelial eddies in papillary urothelial neoplasms: a distinct morphologic pattern with low risk for progression.
We encountered an undescribed histologic feature of papillary urothelial neoplasms: "urothelial eddy", which was histologically reminiscent of squamous eddy of irritated follicular keratosis of the skin. A review of 756 patients with transurethral resection of bladder tumor revealed 10 patients (1.3%) of papillary urothelial neoplasms with urothelial eddies. All cases were male with a median ag...
