Diabetic Dermopathy Diagnosis and Management

Clinical Presentation and Diagnosis

The presence of intact sensation rules out significant peripheral neuropathy, which is a critical distinguishing feature in diabetic patients with brown discoloration on their feet, according to the American Diabetes Association 1, 2
Strong pulses and warm feet exclude peripheral arterial disease and active infection in diabetic patients, as stated by the American Heart Association 3, 4

Active Charcot Neuro-osteoarthropathy (CNO) should be suspected in diabetic patients with neuropathy presenting with a unilateral red, warm, swollen foot, but intact sensation makes CNO unlikely, as noted by the American Diabetes Association 1, 2
The presence of strong pulses and warmth without swelling or temperature asymmetry argues against active CNO, according to the American Diabetes Association 1
Infection is characterized by ≥2 classic inflammatory signs, including erythema, warmth, swelling, pain/tenderness, and purulent secretions, as defined by the Infectious Diseases Society of America 4, 6

Perform annual comprehensive foot examination, including monofilament testing and pulse palpation, to screen for microangiopathic complications and cardiovascular risk, as recommended by the American Diabetes Association 3, 9
Focus management on preventing and treating associated microangiopathic complications, rather than the diabetic dermopathy itself, according to the American Diabetes Association 3, 9
