A 43 -year-old man was treated with pazopanib for metastatic renal cell carcinoma (RCC) with imaging studies suggesting a partial response to treatment.
However, the patient presented numerous times with severe testicular pain and gradually increasing priapism. He underwent an inguinal orchidectomy for symptom control. Histopathology confirmed invasion of the cord and tunica vaginalis with metastatic RCC. Further CT of the abdomen and pelvis suggested non-progression of the disease. The patient continued to develop priapism for several weeks before imaging studies confirmed disease progression; a month later the patient died. Genital involvement in metastatic RCC is unusual but should alert clinicians to the possibility of disease progression.
