Malignant lymphoma of the urethra: report of a case with detection of Epstein-Barr virus genome in the tumour cells.

abstract：AIMS:p16, a tumour suppressor gene located at 9p21 chromosome and involved in cell cycle regulation, is often inactivated in lung carcinoma. Inactivation is also supported by the loss of p16 protein, a strong inhibitor of cyclin-dependent kinase (CDK) 4 and 6. The aim of this study was to examine alterations of p16 bot...
