Chronic Rash Unresponsive to Topical Steroids

Clinical History

‍55-year-old female with chronic venous insufficiency and type 2 diabetes. Bilateral rash on both shins for two months, mildly pruritic. Well-demarcated, brownish-red patches with mild scaling. No weeping or vesicles. On triamcinolone 0.1% twice daily for two months with minimal improvement that worsens again when she stops the steroid.

Clinical Question

She’s seeing only minimal improvement with a mid-potency steroid and it flares when she stops. What am I dealing with, and should I step up treatment or refer?

Specialist Guidance

‍The history and morphology are consistent with stasis dermatitis. The bilateral shin distribution, brownish discoloration, and venous insufficiency history all fit. The steroid likely isn’t working because the underlying venous hypertension hasn’t been addressed.

Topical steroids alone won’t clear this. Start compression therapy, 20–30 mmHg graduated stockings. Check an ABI first given her diabetes. Keep the triamcinolone short-term for symptom relief while the compression takes effect. Steroid-unresponsive rashes on the lower legs in older patients with venous disease are usually venous in etiology, not a resistant dermatitis requiring dose escalation or referral.

No derm referral needed.

Outcome

ABI normal bilaterally. Started compression stockings, continued short-term topical steroid. Rash improved significantly within six weeks. Managed entirely in primary care. No referral required.
