Dermatitis (Contact, Seborrheic & Nummular)

Expert diagnosis and relief for contact, seborrheic, and nummular dermatitis — itchy, inflamed skin treated with personalized care at Miami Skin Center.

Types of Dermatitis We Treat

Contact Dermatitis — triggered by direct contact with allergens (nickel, latex, fragrances) or irritants (soaps, detergents, chemicals). Patch testing helps identify the exact cause.

Seborrheic Dermatitis — a chronic condition causing red, scaly, greasy patches on the scalp, eyebrows, sides of the nose, and chest. Linked to Malassezia yeast and oily skin.

Nummular Dermatitis — coin-shaped, intensely itchy plaques, often on the arms, legs, and trunk. Common in dry skin conditions and adults.

Treatment Options

Topical corticosteroids and calcineurin inhibitors (tacrolimus, pimecrolimus)
Medicated shampoos containing ketoconazole, selenium sulfide, or zinc pyrithione
Patch testing to identify contact allergens
Emollient-rich moisturizers and gentle cleansers
Systemic therapy for severe or widespread cases

Living With Dermatitis

Identifying and avoiding triggers is the cornerstone of long-term management. Our dermatologists create individualized plans to help you achieve clear, comfortable skin.

Frequently asked questions

How do I know if I have contact vs. seborrheic dermatitis?

Contact dermatitis usually appears at the site of allergen/irritant contact and clears when exposure stops. Seborrheic dermatitis is chronic, affects oily areas (scalp, face), and tends to recur. A board-certified dermatologist can diagnose the type with a thorough history and, when needed, patch testing.

Is dermatitis contagious?

No. Dermatitis is not contagious — it is an inflammatory reaction of your own immune system or skin barrier, not an infection.
