title: Collision metastasis of bladder and prostate carcinoma to a single pelvic lymph node.
abstract: Genitourinary organs are at greater risk for multiple primary malignant neoplasms because of the high incidence of these tumours as primaries among all other organs. We present a case of prostate and bladder carcinoma metastasized to a single pelvic lymph node, called a "collision" metastasis, in a patient with four primary tumours.
