Quick answer: Eczema includes several inflammatory skin conditions with different causes and treatment priorities. This guide compares eight common conditions, then explains how appearance patterns and body-area names fit alongside them.
Common types of eczema
Dermatitis means skin inflammation. Clinicians often use eczema and dermatitis interchangeably for eczematous rashes; the complete name identifies the condition. Atopic dermatitis is one common form.
Use the five columns to compare each condition's appearance, usual location, contributing factors and treatment priority. Select a condition name for a detailed guide.2, 10
| Type | Characteristic appearance | Usual locations | Contributing factors | Treatment priority |
|---|---|---|---|---|
| Atopic dermatitis | Recurrent itchy, dry, inflamed patches. | Cheeks and outer limbs in babies; often folds, hands or face later. | Skin-barrier differences, immune activity and inherited tendency. | Daily skin care plus treatment matched to inflammation and severity.1 |
| Contact dermatitis | Itchy or burning inflammation; sometimes blisters or cracks. | Areas exposed to an irritant or allergen, often the hands or face. | Irritant: direct irritation. Allergic: a delayed immune reaction to a skin exposure. See the allergic contact dermatitis guide. | Reduce the responsible exposure and treat inflammation; consider patch testing for allergy. |
| Nummular eczema | Itchy, round or oval patches. | Often arms or legs. | Dry skin and other triggers can contribute; the cause varies. | Treat inflammation and dryness; compare ringworm and eczema when the diagnosis is uncertain. |
| Dyshidrotic eczema | Small, deep, itchy blisters followed by peeling. | Sides of fingers, palms or soles. | Often recurrent; sweating, irritation or contact allergy may contribute. | Control inflammation and protect the hands or feet; assess relevant exposures. |
| Asteatotic eczema | Very dry skin with a cracked-paving pattern. | Commonly the shins. | Marked dryness, often aggravated by low humidity or harsh washing. | Restore moisture, reduce drying exposures and treat active inflammation.4 |
| Seborrheic dermatitis | Flaking or greasy-looking scale with inflammation. | Scalp, eyebrows, nose folds and other oil-rich areas. | A skin response involving Malassezia yeast and other factors. | An appropriate antifungal or antidandruff treatment, with inflammation control when needed. |
| Stasis dermatitis | Inflamed skin with swelling and often brown discoloration. | Lower legs and ankles. | Venous circulation problems in the legs. | Address the circulation problem as well as the rash; compression requires clinical assessment.8 |
| Neurodermatitis Lichen simplex chronicus | One or more localized, thick, leathery patches with prominent skin lines. | Often the neck, scalp, arms or ankles. | Repeated itching, scratching or rubbing, sometimes starting with another skin condition. | Relieve itch and inflammation, protect the area from repeated rubbing, and assess what started the itch.6 |
Similar-looking rashes can have different causes. Dyshidrotic eczema is known for small hand and foot blisters, but other forms of eczema and some infections can also blister. Ringworm can resemble the round patches of nummular eczema; a clinician may use a fungal scraping when the diagnosis is uncertain. The appearance and history guide the assessment.
Appearance patterns and overlapping labels
Type counts and overlapping conditions
This guide compares eight commonly discussed conditions, including asteatotic eczema. Other guides group them differently. Body-area names and appearance labels can overlap with the same diagnosis, so counting every label as a separate type is misleading.
Atopic dermatitis can coexist with contact dermatitis or another eczema pattern. A change in symptoms is a reason to review the diagnosis and exposures.
Appearance labels add detail to the diagnosis
Papular eczema describes small, raised bumps. A papular or follicular pattern can occur in atopic dermatitis, so the label adds detail about appearance. Our papular eczema guide compares these bumps with lookalikes.3
Acute, subacute and chronic describe the activity and appearance of a rash. These features can overlap rather than following a fixed sequence. See Eczema Symptoms and Pictures: Early Signs and Skin Changes for clinical photographs and recognition clues.10
Eczema by body area
A body-area name tells you where the rash occurs; the underlying condition determines the care it needs. These comparisons help you choose a focused guide.10
| Body area | How to compare | Focused guide |
|---|---|---|
| Face | Atopic, contact and seborrheic dermatitis can all affect the face. Scale around the eyebrows and nose folds is a reason to compare seborrheic dermatitis. | Facial eczema |
| Eyelids | Atopic dermatitis, irritation and contact allergy are possibilities. Skin products and substances transferred from the hands may be relevant exposures.12 | Eyelid dermatitis |
| Scalp | Compare atopic or contact dermatitis with seborrheic dermatitis. Product exposure and the distribution of scale help guide the assessment. | Scalp eczema |
| Neck | Recurrent patches can reflect atopic or contact dermatitis. A persistently rubbed, thickened patch also raises neurodermatitis as a possibility. | Neck eczema |
| Shoulders and back | Compare the shape and distribution of patches as well as the body area. Distinct round or oval patches are a reason to consider nummular eczema. | Shoulder and back eczema |
| Hands | Hand eczema can involve atopic dermatitis, irritation or contact allergy. Small, recurring blisters on the palms or finger sides suggest a dyshidrotic pattern. | Hand eczema |
| Legs | Round patches, cracked dry skin and a lower-leg rash with swelling suggest different possibilities. Compare nummular, asteatotic and stasis dermatitis above. | Leg eczema |
| Feet in children | Juvenile plantar dermatosis, or sweaty sock syndrome, is a related childhood foot condition. Shiny, sore, cracked weight-bearing skin differs from the deep blisters typical of dyshidrotic eczema.5 | Sweaty sock syndrome |
| Breasts | Atopic and contact dermatitis can affect breast skin. The distribution and exposure history help distinguish them; symptoms concentrated on the nipple or areola need more focused assessment. | Breast eczema |
| Nipples | Nipple eczema can be atopic, irritant or allergic. Persistent one-sided nipple changes need examination because other conditions can look similar.11 | Nipple eczema and breastfeeding |
Treatment priorities by eczema type
The table identifies the main treatment priority for each condition. A clinician also considers age, body area, severity and any complicating infection or contact allergy. These factors help determine which medicine, strength and duration are appropriate.7, 10
For atopic dermatitis, gentle skin care supports the treatment plan, while active inflammation may also need prescription treatment. Severe or persistent symptoms deserve reassessment and a discussion of additional options. Our atopic dermatitis care and treatment guide explains the next steps.7
For dry, eczema-prone skin, Happy Cappy Daily Shampoo & Body Wash provides fragrance-free cleansing without SLS or SLES. Happy Cappy Moisturizing Cream uses glycerin to attract moisture, petrolatum to retain it, and licorice root extract to help calm the look of redness. These steps support care alongside any prescribed treatment.
Signs that a rash needs medical assessment
Seek an examination when the diagnosis is unclear, treatment is not helping, flares keep returning, or itch disrupts sleep and daily life. Prompt care is important for spreading painful inflammation, warmth, pus, fever, or feeling unwell. A suddenly painful blistering rash in someone with eczema also needs urgent assessment.9
