Penile Calciphylaxis.

A 66-year-old male presented with five days of penile pain and ulceration. The patient had a history of stage 5 chronic kidney disease and repeatedly declined hemodialysis. Wound and urine cultures were unrevealing. CT of the abdomen and pelvis did not reveal any evidence of Fournier's gangrene but identified diffuse severe calcific vasculopathy. Urology and dermatology agreed on the diagnosis of penile calciphylaxis. While diagnosis of calciphylaxis often includes histologic evidence of obstructive vasculopathy, biopsy of penile calciphylaxis is contraindicated due to increased morbidity and mortality. Management focuses wound care and correction of electrolyte abnormalities responsible for calcium deposition.
