Penile necrosis due to calciphylaxis in a patient of end stage renal disease.

A case of a 72-year-old diabetic, hypertensive male with end stage renal disease as a result of the underlying condition of calciphylaxis, presenting with gangrene of the glans penis is reported. In calciphylaxis, calcification of small and medium-sized arteries occurs, which may result in ischemia and gangrene. A computed tomography scan of the lower abdomen, pelvis, and the upper thigh was performed, which showed diffuse and extensive calcification of the walls of the small and medium-sized arteries, with almost complete obliteration of the lumen of the small arteries. A 3-dimensional reconstruction of the penis using volume rendering technique, demonstrated the ulceration of the glans penis in an exquisite manner. The appearance is so peculiar that no histological confirmation is needed. A review of relevant literature related to the etiopathogenesis, radiological findings, treatment, and prognosis is also discussed.
