Nummular Dermatitis

Nummular (discoid) dermatitis is inflammation of the skin characterized by coin- or disc-shaped lesions. ( The name comes from the Latin word "nummus," which means "coin.") The disorder is recurrent and chronic, and may appear at any age, although it is most common in people in their 60's. Nummular dermatitis does not appear to be a genetic condition, is not related to food allergies , and is not contagious. The coin-shaped patches can affect any part of the body, but the legs and buttocks are the most common areas. Flare-ups are associated with dry skin, so the winter season is a particularly bad time for those with this condition. Other conditions that need to be considered when looking at nummular dermatitis are psoriasis, tinea corporis, and parapsoriasis (although this is usually not itchy). Drug eruptions have been reported as presenting with eczema or nummular dermatitis appearance. In situations where there is doubt, KOH examination or bacterial swabs and / or biopsy may be required. Patch testing can be useful. In some cases where a contact dermatitis can be identified, clearing can be achieved by avoidance of the allergen.

Nummular Dermatitis is a very common type of skin disorders but is very dangerous also. Nummular dermatitis, is a skin disorder situation in which ruption may begin with one or numerous round red plaques with tiny overlying blisters. The plaques often enlarge to several centimeters with clearly marked edges, and overlying scale may be prominent. Swelling and oozing occur in newer lesions and itching can be mild to severe. Nummular dermatitis can resolve completely, though typically it persists for years. Flare-ups most often occur during the winter months, although humid summers can aggravate the condition. Sometimes a skin biopsy is obtained to confirm the diagnosis and to rule out other disorders. Bath oils and emollients are important in the daily management of nummular dermatitis. Topical corticosteroids and tar preparations reduce the itch and inflammation. Moisturizers and control of dryness help minimize the frequency and severity of the disorder.
