title: Sarcomatoid Renal Cell Carcinoma Metastasis to the Penis.
abstract: Secondary cancers of the penis are extremely uncommon with less than 300 cases reported in the past 100 years. These cancers are most frequently a result of an aggressive or poorly managed primary prostate or bladder cancer and rarely a metastasis from a primary kidney tumor. Currently, there is no published literature which describes the spread of sarcomatoid renal cell carcinoma (SRCC) to the penis. In this report, we present a 55-year-old-man who presented with a large right-sided SRCC which metastasized to the base of his penis within 1 month of symptom onset. We also discuss the possible route of metastasis based on primary tumor size and location within the retroperitoneum.
