Skin Diseases

Common types of skin diseases and conditions affecting numerous people

Numerous skin problems affect humans. Some common skin issues may have similar, and hence you must understand the difference between them.

People must consult a dermatologist to identify and treat any skin condition.

Here are some Common skin diseases separated by type.

Temporary skin conditions

1. Acne

One of the most common skin problems is acne, and this comes in many forms like pustules, papules, nodules, and cysts.

Pustules are red pimples, having pus at their tips, and papules are pimples with raised red bumps caused due to infected hair follicles. Nodules are found below the skin surface and are painful. Cysts too are painful, pus-filled pimples that are usually large and a result of infections under the skin. All types of acne can be treated with creams and ointments. However, some may require medications.

2. Hives

Hives are raised, itchy welts that occur due to allergic reaction in the body or exterior factors like stress, illnesses, or tight fitted clothing. Hives can be cured with antihistamines and prudent practices.

3. Warts

Warts are raised bumps on the skin surface, occurring due to the human papillomavirus (HPV). As warts are contagious, they can spread to any part of the body.

Common warts usually develop on the hands, feet, and joints, although they could occur anywhere. Most of them disappear by themselves. However, unsightly warts require treatment with liquid nitrogen or medicated creams.

4. Fungal nail infection

Fungus appearing near, under, and around the nails of the hands and feet indicate a fungal infection. The accumulated fungus can cause the nail’s edges to crumble away, thus creating white-yellowish scaling and flaking on the nail’s surface. To treat a nail fungal infection, there’s a need for anti-fungal creams.

5. Cold sore

A painful, red, fluid-filled blister mostly occurring near the mouth is known as cold sore. Itching or burning sensation may occur on the site prior to the sore becomes visible.

Permanent skin conditions

Several skin conditions last longer. Some skin problems may begin in childhood and continue until adult years. Though some conditions may not always be present, they may flare up at certain times.


  1. Seborrheic dermatitis

In infants, this issue is referred to as cradle cap. Oily and scaly patches form on the child’s skin, mostly affecting the scalp area. This skin condition is harmless and most of the time cures by itself.

In adults, it might appear anywhere, and may first flare up and then go away forever. The affected skin turns red, swollen, and oily. A white-to-yellow crust might develop on the skin’s surface. Multiple treatments can be used to give relief from symptoms.


  1. Moles

Moles are formed by skin cells bunching up and tissues surrounding them. There are no symptoms of moles, but if they appear, they must be checked regularly to see if they grow bigger or appear abnormal or change their colour.


  1. Melanoma


Melanoma can be the result of abnormal moles. It is a critical and dangerous type of skin cancer. Moles of irregular shapes, uneven colours, and ragged edges must be checked immediately. Patients with melanoma might have to undergo surgeries or chemotherapy or radiation treatments depenging on their condition.


  1. Rosacea

This is a skin condition that is linked with redness. There are four subtypes of rosacea that may trigger other symptoms too. These types are:

1.  Erythematotelangiectatic rosacea – This type leads to skin redness, noticeable blood vessels, and flushing.

2. Ocular rosacea – This may cause red and irritated eyes, inflamed eyelids, and indications that look like a sty.

3. Papulopustular rosacea – This type too leads to redness of skin but along with swelling. Sometimes, it can be accompanied by breakouts that appear to be like acne.

4. Phymatous rosacea – This makes the skin thick and bumpy in texture.

There isn’t any known cure for rosacea. However, its symptoms can and must be cured to keep the condition under control.

5. Lupus

Lupus is a complicated disorder that differs from individual to individual. The condition strikes the immune system, leading to pain and inflammation.

While lupus can impact any body part, symptoms on the skin are red patches or ring shapes, sunburn-like rashes on the nose and cheeks, or circular rashes that are not itchy or painful. Patients may experience other symptoms like fever, headaches, fatigue, and joints pain.

Treatment for lupuc involves several strength medications made to reduce the effects of damage caused by lupus.

6. Psoriasis

Psoriasis forms patches of abnormal skin that are usually red, scaly, and itchy. The different types of psoriasis are plaque psoriasis, pustular psoriasis, erythodermic psoriasis, inverse psoriasis and guttate psoriasis.

7. Eczema

The condition mostly affects infants and young children continuing into their adulthood. Symptoms of eczema are rashes on the scalp, face, neck, behind the elbows, or on the neck or ankles or legs. These rashes feel itchy and could become bumpy and thick or may change colour. In adults, the rashes can cover numerous parts of the body leading to dry skin that becomes permanently itchy.

There are various eczema types, each having their own symptoms. There isn’t any known treatment for eczema. It either cures on its own or its symptoms can be treated with medications.

8. Vitiligo

Vitiligo is a skin condition that causes loss of pigmentation. The main symptoms of vitiligo are white patches of skin. Vitiligo appears in areas exposed to the sunlight. People with this problem also lose their hair colour at an early age.

Some may be affected by the symptoms in one area, while others may find it spreading slowly. Vitiligo cannot be cured completely, but there are some medical and surgical treatments available for curing it.
