As intracavernosal injection of vasoactive drugs has become more common for the diagnosis and treatment of impotent patients, priapism resulting from vasoactive drug injection has frequently occurred. Intracavernosal injection therapy should be prescribed by doctor for the optimal titration of drug dosage and patient education of self injection, because mal-use or abuse of this drug can result in priapism and corporal fibrosis. We report a case of priapism resulted in severe corporal fibrosis by abuse of intracavernosal self-injection.

Renal angiomylipomas are uncommon benign neoplasms composed of mature fat tissue, thick-walled blood vessels and smooth muscle in varying proportions, which can be commonly diagnosed by those unique fat nature in abdominal ultrasonography and abdominal CT scan. Renal angiomyolipomas without demonstrable fat component are rarely reported which is difficult to differentiate from renal cell carcinoma. We report a case of renal angiomyolipoma without demonstrable fat component which was proven to positive HMB-45 stain after partial nephrectomy.
