I have bleeding sores on my hands and feet that have persisted for ten months; what evaluation and management are recommended?

Bleeding Sores on Hands and Feet for 10 Months

You need urgent evaluation for an underlying systemic vasculopathy or autoimmune disease, as chronic bleeding ulcers on hands and feet lasting 10 months are highly suspicious for conditions like livedoid vasculopathy, Behçet's syndrome, or other vasculitic/autoimmune disorders that require specific immunosuppressive treatment.

Immediate Diagnostic Workup

Your evaluation must include:

Laboratory Testing:

• Complete blood count with peripheral smear
• Prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen 1
• Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)
• Antinuclear antibodies (ANA), antiphospholipid antibodies, and ANCA panel
• Thrombophilia workup (protein C, protein S, factor V Leiden, antithrombin III)
• Cryoglobulins 2

Skin Biopsy: A punch biopsy from the ulcer edge is essential to differentiate between vasculitic causes, thrombotic vasculopathy, and other inflammatory conditions 3, 2.

Vascular Assessment: Rule out peripheral arterial disease with ankle-brachial index and consider vascular surgery consultation 4, 2.

Most Likely Diagnoses to Consider

Livedoid Vasculopathy:

• Presents as painful ulcerations on lower extremities (can affect hands/feet) that heal with white atrophic scars (atrophie blanche)
• Caused by thrombotic vasculopathy rather than true vasculitis
• Treatment: pentoxifylline, nifedipine, and anticoagulation (warfarin) 3

Behçet's Syndrome:

• Mucocutaneous involvement with recurrent ulcers on hands/feet
• Initial treatment: topical corticosteroids for isolated ulcers 4
• For persistent lesions: colchicine as first-line systemic therapy 4
• For refractory cases: azathioprine, interferon-alpha, or TNF-alpha inhibitors 4

Other Vasculitic/Autoimmune Causes:

• Antiphospholipid syndrome, systemic lupus erythematosus, rheumatoid arthritis, ANCA-associated vasculitis 2
• These require immunosuppressive therapy tailored to the specific diagnosis

Critical Management Pitfalls

Do NOT assume these are simple diabetic foot ulcers without ruling out systemic disease—20-23% of non-healing wounds refractory to standard care have vasculitic or autoimmune causes 2.

Do NOT perform vascular intervention alone if autoimmune disease is present—patients with autoimmune disease have 50% skin graft failure rates compared to 97% success in those without autoimmune disease 2.

Do NOT delay referral—you need both dermatology and rheumatology consultation urgently. A multidisciplinary approach significantly improves outcomes for these challenging wounds 2.

Immediate Wound Care While Awaiting Diagnosis

• Clean wounds daily with water or saline 5
• Apply sterile, non-adherent dressings to control exudate and maintain moist wound environment 5
• Do NOT use topical antiseptics or antimicrobial dressings—these do not improve healing in chronic ulcers 6
• Avoid walking barefoot or in thin-soled slippers to prevent trauma 7
• Elevate affected limbs when possible

Treatment Algorithm Based on Final Diagnosis

If Livedoid Vasculopathy confirmed:

• Pentoxifylline + calcium channel blocker (nifedipine) + anticoagulation (warfarin) 3

If Behçet's Syndrome confirmed:

1. Start topical corticosteroids immediately 4
2. Add colchicine for prevention of recurrence 4
3. If no improvement in 2-4 weeks, escalate to azathioprine 2.5 mg/kg/day 8, 4
4. For severe refractory cases, consider interferon-alpha or TNF-alpha inhibitors (infliximab/adalimumab) 4

If other vasculitis/autoimmune disease:

• Treatment depends on specific diagnosis but typically requires systemic corticosteroids plus steroid-sparing immunosuppressives 2

The 10-month duration of your symptoms indicates this is NOT a simple wound healing problem—you have an underlying systemic disease that requires identification and disease-specific treatment to achieve remission and prevent permanent scarring or disability 3, 2.
