Intravenous pyogenic granuloma of the renal vein: A rare morphological differential diagnosis to renal cell carcinoma.

We report the fourth case reported world-wide of an intravenous pyogenic granuloma (IVPG) originating from a renal vessel. This rare and benign tumor is mostly found in the head and neck region and has been described very rarely in association with the kidneys. By reviewing the characteristics of all published cases we suggest diagnostic and therapeutic strategies for patients with possible IVPG in the renal vessels out of the view of highly experienced surgeons specialized in advanced Inferior Vena Cava-thrombectomy.

Peyronie's Disease: Nonsurgical Therapy Options.

Peyronie's disease (PD) is a fibrous inelastic scar of the tunica albuginea, leading to penile deformity, penile curvature, shortening, narrowing, and painful erections that subsequently lead to painful or unsatisfying sexual intercourse. No consensus exists yet on the ideal management of PD. This fact is a result of our limited knowledge of its etiology and causative factors. The acute presentation of PD is treated conservatively, and surgical approaches are only attempted if severe curvature, narrowing, or indentation persists for more than 1 year; PD stability exists for at least 3 months; curvature impedes sexual intercourse; and severe penile shortening occurs. This review focuses on new developments for conservative treatment strategies for PD.
