As dermatitis one is inflammatory reaction of the skin indicated that mainly the dermis detected (dermis). The term “ eczema ” is a synonym for this . However, dermatitis is a broader definition and eczema should be named more precisely as dermatitis eczematosa .

In the ICD-10 classification in group L20 – L30 (“dermatitis and eczema”), the two names are used interchangeably, and accordingly those diseases are listed here that do not fall into it, as their essential characteristics are classified into other disease groups correspond better and not an intolerance reaction as with the eczema group is in the foreground:

• Bath dermatitis ( cervical dermatitis ), an infection caused by cercariae from various flukes
• Dermatitis herpetiformis Duhring , a chronic, recurrent autoimmune disease with subepidermal blistering
• Dermatitis exfoliativa neonatorum ( Staphylococcal scalded skin syndrome , SSSS), staphylogenic Lyell syndrome
• Dermatitis factitia , an artificial disorder (ICD-10: L98.1) due to self-harm
• Ulcerative dermatitis , a vasculitis with isolated ulcerations
• Perioral dermatitis (syn. Rosacea-like dermatitis ), an inflammation of the skin of the face caused by excessive use of cosmetics
• Stasis dermatitis , usually at the start of venous circulation disorders such as Chronic venous insufficiency due
• Skin diseases due to exposure to radiation , such as
  • Photodermatoses due to excessive sun exposure ( sunburn is a dermatitis solaris ), photoallergic or photoxic reactions (e.g. berloque dermatitis , meadow grass dermatitis , buckwheat disease ) or the
  • Radiation dermatitis ( radiodermatitis ) as a result of ionizing radiation
• Xeroderma

synonym

According to ICD-10, the term eczema is synonymous with dermatitis for:

• Allergic contact eczema (allergic contact dermatitis) and toxic contact eczema (toxic contact dermatitis), for example through contact with plants or vegetable products
• Atopic eczema (atopic dermatitis, neurodermatitis)
• Dyshidrotic eczema , sometimes just a manifestation of eczema on the inside of the hands or feet, or between the fingers or toes
• Exfoliative dermatitis
• Numular eczema
• Seborrheic eczema (seborrheic dermatitis)
• many dermatitis caused by orally, enterally or parenterally ingested substances such as medication
• Diaper eczema (diaper rash)

Diagnosis

In order to determine the diseases of the skin already mentioned above, one must be familiar with the theory of efflorescence . The efflorescence theory makes the characteristics of all diseases appear visible on the skin.

The best known include:

• the spot ( macula )
• the papule , an elevation lying above the skin level. It is caused by a thickening of the epidermis.
• the bubble ( vesicle ) and the bladder ( Bulla ), fluid-filled cavities that are raised above the skin level
• the wheal ( urtica ), a circumscribed, acute edema in the dermis, which is caused by the escape of plasma from the vessels
• the cyst
• the skin flake ( squama )
• the rhagade or fissure , a gap-shaped skin tear
• the ulcer (ulcer)

treatment

Local therapeutics

Many skin diseases are treated with topical therapeutic agents. The advantages are:

• Effect at the source of the disease with a higher concentration of the drug
• Side effects are less: z. B. glucocorticoids

The three components of local therapeutics

• Basic material (e.g. ointment bases, carriers)
• Active ingredient
• Additives

Local therapeutic forms

• Application of creams, ointments, shaking mixes
• Create a bandage
• Apply a moist envelope
• Additives for corresponding full or partial baths

Systemic medication

Many diseases also require targeted drug treatment. Some of the most important preparations are:

• Antibiotics (for bacterial superinfection or genesis)
• Antifungal drugs (for superinfection by fungi)
• Antihistamines (symptomatic of itching)
• Glucocorticoids (if severe)
• Retinoids (for psoriasis , acne , rosacea )
• Immunosuppressants (e.g. Delmitid ) (in the context of autoimmune diseases, including psoriasis)
