Primary and secondary malignancies of the penis: ultrasound features.
Cancer of the penis is a rare neoplasm in developed countries but worldwide represents a significant health problem. In this study, the ultrasonographic features of primary and secondary malignant lesions of the penis are described. Squamous cell carcinoma usually presents as a hypoechoic lesion with heterogeneous appearance. Invasions of the corpora cavernosa and the corpus spongiosum are appreciable. B-cell lymphoma presents as well-vascularized mass, a plaque, or ulcers in the penile skin. Penile metastases results from hematogenous or lymphatic spreading of distant tumors or, more frequently, as penile infiltration by tumors from adjacent organs. Diffuse corporeal or nodular involvement can result.
