Tumors of the penis (both malignant and benign) are fairly rare diseases. Even more rare are cases of metastasis of malignant tumors of other organs to penis. The clinical picture of penile metastatic lesions is highly heterogeneous, ranging from small nodules to massive lesions with or without ulceration, obstructive or irritative symptoms, hematuria or priapism. This article reviews the literature on this rare nosology, as well as from personal experience presents a clinical observation of a rare disease: priapism secondary to bladder cancer metastasis.
