Priapism as the Presenting Feature of Renal Cell Carcinoma

Abstract

We describe a case of renal cell carcinoma with metastasis to the penis clinically presenting with priapism. Six such cases found in the literature are reviewed. Neoplastic disease is far advanced in these cases and therapy is only palliative.KEY WORDS: malignant priapism, metastatic disease of penis, renal cell carcinoma metastatic to penis, unusual renal cancer metastasis

Malignant priapism as the initial clinical manifestation of metastatic renal cell carcinoma with invasion of both corpora cavernosum and spongiosum

“…Only two other case reports have described priapism as a presenting feature of a right-sided renal cell carcinoma. 2 In almost all cases of metastatic penile lesions the corpora cavernosa are involved while the presence of spongiosum invasion is rare. 3 In patients who present with priapism and have no history of penile/ perineal injury, sickle cell disease, use of intracavernous injections, psychotropic drugs or other known cause of priapism the possibility of an underlying malignant process must be considered.…”
