Summary
This report details a rare case of unilateral penile gangrene in a patient with type 2 diabetes. The condition, linked to iliac artery stenosis, ultimately required amputation and led to a novel Mycobacterium gordonae infection.
Area of Science:
- Urology
- Endocrinology
- Infectious Diseases
Background:
- Diabetes mellitus type II is a prevalent condition associated with numerous complications.
- Penile gangrene is an exceptionally rare but severe complication of diabetes.
- Iliac artery stenosis can compromise blood flow, potentially contributing to ischemic events in the lower extremities and genitalia.
Observation:
- A patient with diabetes mellitus type II presented with unilateral penile gangrene.
- The gangrene was associated with ipsilateral partial stenosis of the common iliac artery.
- Despite angioplasty, stenting, rehydration, and improved glycemic control, the penile lesion did not resolve, necessitating amputation.
Findings:
- This case represents the first reported instance of unilateral penile gangrene in a patient with diabetes mellitus.
- Postoperatively, the patient developed bilateral basal pneumonia with significant growth of saprophytic Mycobacterium gordonae from bronchial aspirate.
- This is also the first report of Mycobacterium gordonae infection in a diabetic patient.
Implications:
- Highlights the importance of considering rare vascular complications in diabetic patients.
- Suggests a potential, albeit unusual, pathogenic role for Mycobacterium gordonae in immunocompromised individuals.
- Underscores the need for comprehensive management of vascular and infectious complications in complex diabetic cases.
