Dyshidrotic Eczema

Dyshidrotic eczema is a chronic, relapsing form of dermatitis characterized by the eruption of small, intensely pruritic, fluid-filled vesicles on the palms, soles, and lateral aspects of the digits. While historically misnamed "dyshidrosis" due to the incorrect assumption of sweat gland dysfunction, it is now classified as a localized form of idiopathic eczema.

The exact etiology remains idiopathic, though it is associated with a multifactorial interplay of genetic predisposition, environmental triggers, and immune dysregulation. Known triggers include metal hypersensitivity (nickel, cobalt), contact allergens, stress, and seasonal humidity changes.

The condition involves an exaggerated T-cell-mediated immune response. Keratinocytes in the epidermis undergo spongiosis—intercellular edema—leading to the formation of vesicles. Despite the name, sweat glands are histologically normal; the pathology is centered on epidermal inflammation rather than sudoriferous gland duct obstruction.

Dyshidrotic eczema typically affects adults between 20 and 40 years of age. It shows a slight female predominance. Prevalence is estimated at approximately 0.5% of the general population, with higher rates among individuals with a personal or family history of atopy.

• Atopic dermatitis
• Hyperhidrosis
• Exposure to metal salts (nickel/cobalt)
• Emotional stress
• Contact dermatitis
• Smoking

A. Early Symptoms

• Intense pruritus or burning sensation in localized areas.


• Sudden onset of pinpoint, clear vesicles. B. Common Symptoms


• Deep-seated "tapioca-like" vesicles on palms and sides of fingers.


• Recurrent outbreaks. C. Advanced Symptoms


• Desquamation (peeling).


• Painful fissuring and cracking of the skin.


• Lichenification (thickening of the skin). D. Emergency Symptoms


• Signs of secondary bacterial infection (pus, warmth, spreading erythema, fever).

Inspection reveals symmetric, clear, 1-2mm vesicles on the lateral fingers and palms. Palpation may detect thickening or peeling. There is an absence of systemic involvement or vital sign abnormalities.

A. Clinical Assessment: Diagnosis is primarily clinical based on characteristic morphology and distribution.
B. Laboratory Testing: Rarely required, unless ruling out infections.
C. Imaging Studies: Generally not indicated.
D. Functional Tests: Patch testing to rule out contact dermatitis.
E. Biopsy Findings: Spongiosis and intraepidermal vesiculation.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Tinea manuum, contact dermatitis, bullous tinea.

Test Name: Potassium Hydroxide (KOH) Prep
Type: Skin Scraping
Purpose: Rule out fungal infection.
Expected Findings: Negative for hyphae.
Interpretation: Negative result supports dyshidrotic eczema over tinea.

None typically required for diagnosis.

• Tinea manuum (often unilateral)
• Allergic contact dermatitis
• Pustular psoriasis

Secondary bacterial infection (cellulitis), chronic skin changes, and psychological distress from cosmetic appearance.

A. Lifestyle Modifications: Avoidance of known triggers, wearing cotton-lined gloves, and gentle skin cleansing.
B. Preventive Measures: Frequent emollient use to maintain the skin barrier.
C. Medical Treatment:

• High-potency topical corticosteroids (e.g., Clobetasol)


• Calcineurin inhibitors (e.g., Tacrolimus)


• Oral corticosteroids for severe flares


• Phototherapy (PUVA)

Good; condition is often self-limiting or manageable with topical therapy, though recurrence is frequent.

Identification and avoidance of allergens; stress management; barrier protection.
