1. Atopic dermatitis

Atopic dermatitis stands as the predominant manifestation of eczema.

Typically commencing in childhood, usually between 2 months and 5 years of age, it commonly diminishes in severity or resolves entirely by adulthood. Nevertheless, individuals may experience sporadic flare-ups or encounter symptoms for the first time later in life.

Symptoms of atopic dermatitis typically manifest on the arms or within the folds of the elbows or knees, while children may also exhibit symptoms on their scalp and cheeks. It’s imperative to refrain from scratching any eruptions, rashes, or lesions to prevent potential infection.

The precise cause of atopic dermatitis remains elusive. Nonetheless, the condition arises when the natural barrier of the skin weakens, rendering it less capable of shielding against irritants and allergens. Atopic dermatitis is likely triggered by a combination of factors, including genetic predisposition, dry skin, immune system dysregulation, and various environmental stimuli such as irritants, stress, and dry conditions.

2. Contact dermatitis

Contact dermatitis arises from a reaction to substances encountered through touch, categorized into two types:

  1. Allergic contact dermatitis: This manifests as an immune system response to an irritant, such as latex or certain metals.
  2. Irritant contact dermatitis: Initiated by direct damage to the skin from chemicals or other substances.

Symptoms of contact dermatitis may manifest within 48 hours following exposure to a triggering substance. These symptoms include:

  • Itchy skin, exhibiting red, pink, or magenta hues; in darker skin tones, this may present as brown, purple, or gray.
  • Sensations of burning or stinging.
  • Development of hives.
  • Formation of fluid-filled blisters.
  • Thickening and toughening of the skin, sometimes resembling leather.

Contact dermatitis occurs upon contact with substances that either irritate the skin or provoke an allergic reaction. Common irritants encompass detergents, bleach, jewelry, latex, nickel, paint, poisonous plants like poison ivy, skincare products including makeup, soaps, perfumes, solvents, and exposure to tobacco smoke.

3. Dyshidrotic eczema

Dyshidrotic eczema, also referred to as pompholyx, is characterized by the formation of small blisters on the hands and feet.

Symptoms of dyshidrotic eczema typically persist for 2–3 weeks and may include fluid-filled blisters that itch, cause discomfort, crack, and flake. These blisters commonly emerge on the fingers, toes, palms, and soles of the feet.

Various factors can contribute to the development of dyshidrotic eczema, including allergies, moist conditions on the hands and feet, exposure to substances like nickel, cobalt, or chromium salt, stress, and tobacco smoking.

4. Seborrheic dermatitis

Seborrheic dermatitis, often termed scalp eczema due to its frequent occurrence on the scalp, presents distinct characteristics.

In infants, seborrheic dermatitis is commonly known as cradle cap, typically resolving without recurrence. However, in adolescents and adults, seborrheic dermatitis tends to persist as an ongoing skin concern.

Symptoms of seborrheic dermatitis encompass scaly, oily patches of skin producing dandruff-like flakes. These patches predominantly manifest in areas abundant with sebaceous glands, such as the scalp, hairline, upper back, nose, and groin. In individuals with darker skin tones, these patches may appear darker than their skin, while in those with lighter skin tones, they may appear lighter.

The etiology of seborrheic dermatitis is likely multifactorial, involving a combination of environmental and genetic influences. Initial triggers, such as stress or illness, incite an inflammatory response in the skin, prompting excessive growth of Malassezia yeast—an organism naturally residing on the skin’s surface. This yeast overgrowth triggers immune system reactions, precipitating characteristic skin changes observed in seborrheic dermatitis.

Additional triggers contributing to seborrheic dermatitis may include hormonal fluctuations, certain illnesses, exposure to harsh detergents or chemicals, cold and dry weather conditions, underlying medical conditions such as Parkinson’s disease, psoriasis, HIV, and acne, as well as certain medications like interferon and lithium.

5. Neurodermatitis

Neurodermatitis, also known as lichen simplex chronicus, represents a form of eczema characterized by the development of 1–2 patches accompanied by intense itching that exacerbates with scratching.

Symptoms of neurodermatitis manifest as thick, scaly, and highly pruritic patches on various parts of the body, including the arms, legs, back of the neck, scalp, soles of the feet, backs of the hands, and genital region. It is crucial to refrain from scratching these patches to prevent worsening symptoms, bleeding, and potential infection.

While the precise cause of neurodermatitis remains unknown, it typically initiates with an itch, and the rash intensifies as scratching persists, as outlined by the American Academy of Dermatology (AAD).

6. Nummular eczema

Nummular eczema, also recognized as discoid eczema, manifests as circular, coin-shaped lesions on the skin, presenting a distinct appearance from other forms of eczema and often accompanied by intense itching.

Symptoms of nummular eczema can persist for several years untreated. Initially, small bumps may emerge on the skin, appearing red or pink on lighter skin tones and dark brown on darker skin tones. These bumps tend to evolve into coin-shaped skin lesions characterized by itchiness, flakiness, or fissures.

The precise cause of nummular eczema remains elusive, although it may arise from underlying factors such as excessively dry skin. Individuals with pre-existing eczema, such as atopic dermatitis, are also more predisposed to developing nummular eczema.

7. Stasis dermatitis

Stasis dermatitis is more prevalent among individuals with poor circulation, as stated by the AAD. It occurs when fluid leaks from weakened veins into the skin, leading to various symptoms such as swelling, redness (in lighter skin tones), or changes in coloration (brown, purple, gray, or ashen in darker skin tones), itching, and pain.

Symptoms of stasis dermatitis predominantly affect the legs and ankles, often resulting in swelling, especially after extended periods of walking, along with sensations of heaviness or aching. Additional symptoms may encompass varicose veins, dry and itchy skin, as well as the formation of open sores.

Stasis dermatitis develops in individuals experiencing blood flow issues in their lower legs, typically due to malfunctioning valves that impede the normal upward flow of blood towards the heart, causing blood to accumulate in the legs.

Seeing a doctor

Seeking medical advice is crucial for anyone experiencing symptoms of eczema or any other skin condition. A dermatologist, a doctor specializing in skin health, can provide a proper diagnosis and recommend the most effective treatment plan tailored to your specific needs. Here are some key reasons why it’s important to see a doctor if you suspect you have eczema:
