A diabetic patient with a black penile tip

This is a report of a patient with diabetes mellitus type II who presented with the rare complication of penile gangrene. The gangrene was unilateral and was associated with ipsilateral partial stenosis of the common iliac ar tery. An angioplasty followed by insertion of a stent, rehydration, and imp roved diabetic control did not improve the penile lesion, and penile amputa tion was carried out. In the postoperative period, the patient developed a bilateral basal pneumonia with a significant growth of saprophyte Mycobacte rium gordonae from the bronchial aspirate. This is the first reported case of unilateral penile gangrene and also that of Mycobacterium gordonae infec tion in a patient with diabetes mellitus. (C) 2000 Elsevier Science Inc.
