Paraphimosis in elderly men.

Paraphimosis occurs when the foreskin of the penis is retracted over the glans and cannot be replaced in its normal position. The tight ring of preputial skin constricts the distal penis causing vascular occlusion, much like a tourniquet. The condition is painful and, if not dealt with quickly, can lead to necrosis of the glans. Simple reduction of the prepuce can be achieved by compressing the edematous fluid out of the glans and repositioning the foreskin. Irreducible paraphimosis is treated by dorsal slit procedure and subsequent circumcision. We present two cases illustrating the treatment techniques and possible complications of paraphimosis in men.

Acquired renal cystic disease and renal cell carcinoma in an allograft kidney.

Acquired renal cystic disease has been reported in the kidneys of patients with end stage renal disease who have been untreated, treated with dialysis or undergone renal transplantation. The incidence of renal tumor development in patients with acquired renal cystic disease is greater than 5% in those undergoing chronic hemodialysis. Recently, cases of renal cell carcinoma occurring with acquired renal cystic disease of the native kidneys of transplant recipients have been reported. Transplant patients have an increased incidence of malignancy when compared to the general population. Including our case, 19 cases of de novo renal neoplasms developing in renal allografts have been reported. To the best of our knowledge we report the longest interval to presentation of a de novo renal tumor in an allograft kidney (228 months) and the first case of renal cell carcinoma associated with acquired renal cystic disease in an allograft kidney.
