Skin disease pictures and symptoms is a free dermatology atlas which also teaches you about skin, hair and nail diseases affecting people with skin of color.
Symptoms of a skin abscess include:
1. A warm, tender and fluctuant (compressible) swelling.
2. The surrounding area ranges in color from deep red to pink.
Symptoms of acne vulgaris include comedones (white heads), open comedones (black heads), papules (pimples), pustules (pus filled swellings), nodules (larger nodules) and cysts (fluid filled swellings).
These swellings usually develop on areas with a high concentration of sebaceous (oil) glands like the face, back, chest and shoulders.
Patients who develop occupational acne can also develop lesions on other parts of their bodies like the hands.
Symptoms of acneiform eruptions include monomorphic (uniform) lesions which can be papules, papulopustules, nodules or cysts. These lesions can develop on parts of the body not normally affected by acne vulgaris like the upper and lower limbs.
Symptoms of alopecia areate include a localized patch without hair that has normal skin on a hair bearing area of the body.
These cutaneous (skin) symptoms of amyloidosis can be divided into
1. Localized Cutaneous Amyloidosis Symptoms which include:
a. Lichen amyloidosis is the most common type of primary localized cutaneous amyloidosis. It affects men more than women and especially those of Chinese descent. Patients presents with a very itchy, hyperkeratotic (scaly) papules (raised areas) which are reddish brown in color. These affected areas may coalesce to form large plaques on the pretibial regions (shins), thighs and feet.
b. Macular amyloidosis affects more women than men and especially those of Asian descent. Patients present with brownish grey spots which may join to form larger patches on their upper back and chest. These lesions may be associated with either severe or mild pruritis (itch).
c. Nodular localized cutaneous amyloidosis (LCA) is the rarest type of primary localized cutaneous amyloidosis. Patients present with firm nodules which range in color from pink to brown. These lesions can be single or multiple and develop on the face, scalp, limbs, feet, soles, trunk and genitalia.
Nodular LCA lesions which are usually just a few centimeters in size or smaller are initially asymptomatic. This means that do not cause any symptoms and they can persist in this state for many years. Eventually patients present due to cosmetic reasons.
2. Systemic Cutaneous Amyloidosis Symptoms include:
a. Petechia (small purplish spots on the skin), purpura (purple colored spots and patches) and ecchymoses (larger reddish-purplish patches) are the most common cutaneous symptoms of primary systemic amyloidosis.
These develop on the skin and mucous membranes due to intracutaneous bleeding or the bleeding that occurs within the skin when the amyloid weakens the blood vessels. They commonly develop on the eyelids, axillae (armpits), umbilicus and around the groin and anal region.
b. Smooth, waxy, yellowish papules (small swellings), nodules (larger swellings) and plaques develop due to dermal infiltration by the amyloid. They commonly develop around the eyelids, in the mouth and on the limbs.
c. The nails may also become brittle, white and develop bands. There may also be onycholysis.
d. Patches of hair loss may also develop or the hair may thin uniformly.
BLISTER BEETLE DERMATITIS
Symptoms of blister beetle dermatitis or Nairobi Fly Dermatitis include vesicles and bullae (blisters) on the skin with associated redness and edema (swelling).
Symptoms of Confetti Hypopigmentation include multiple macules (discolored flat areas) which are around 1-3 mm in diameter. These hypopigmented areas are usually on the arms and legs.
Symptoms of hand eczema include erythematous (red), hyperkeratotic (scaly) areas with fissures and mild edema (swelling) on the hands.
The hands also develop an itchy or burning sensation when they come in contact with potential irritants like water or detergents.
Symptoms of ichthyosis include dry skin with a fish-like scale.
Symptoms of an ingrown toenail include a swollen, warm, erythematous (red) and painful toe.
LINEAR IMMUNOGLOBULIN A (IgA) DERMATOSIS (LAD)
Symptoms of Linear Immunogloblin A dermatosis include:
1. Some patients may develop pruritis or itching before the blisters develop.
2. Tense vesicles and bullae which are roundish and clear though they may also be hemorrhagic. These vesicles and bullae, which may be discrete, can develop on normal or erythematous (red) skin.
3. Sting of beads sign in which vesicles are arranged at the edge of annular (round) lesions or in ring around an old bullae.
4. Cluster of jewels sign in which vesicles are arranged clustered together in a herpetiform pattern.
5. Erosions, ulcers, crusts, and excoriations (scratch marks) are also present.
6. Reddish plaques, annular papules and other lesions which resemble the target lesions of erythema multiforme can also develop in some patients.
In children these lesions are mainly in the anogenital region and lower abdomen.
Symptoms of Morgellons Disease include:
1. Sensations of insects crawling all over the skin and of being stung by insects under the skin.
2. Disfiguring sores which are similar in appearance to insect bites that have been aggravated by persistent picking and scratching. These sores appear suddenly, heal very slowly and can be very itchy. When they heal they leave hyperpigmented (darker than the surrounding skin) scars. The forearms, legs, chest, back and face are the sites that are most commonly affected.
3. The presence of black thread-like substances or fibers on the skin and sores which are usually made of cellulose and therefore thought to be cotton fibers from bandages.
4. Rashes which can be very itchy.
5. Muscle and joint aches
6. Excessive fatigue
7. Difficulty concentrating or paying attention
8. Difficulty remembering things or short term memory loss
9. Difficulty sleeping
Symptoms of onychomycosis or fungal nail infection include changes in the color and the shape of their nail which can become yellowish and thickened.
These changes are initially painless but as the disease progresses, the nails may become painful and cause difficulties walking and performing their occupation.
PAPULAR PRURITIC ERUPTION (PPE)
Symptoms of Papular Pruritic Eruption (PPE) include:
1. Rash with multiple, small (less than 1cm), itchy, red or skin colored papules (pimples). In dark skinned persons, these papules may be hyperpigmented.
2. These papules may be superficially eroded due to the pruritis. Sterile pustules and excoriations may also be present.
3. The generalized papular rash is symmetrical and affects the extremities, trunk, neck, and face. It spares the palms, soles, and mucous membranes of the mouth, nostrils, eyes, and genitalia.
4. Psychological effects can develop due to the disfiguring nature of the rash and the stigmatization that may be associated with it.
Symptoms of Pellagra Dermatitis include:
1. Pellagra dermatitis (pellagroderma) usually begins with erythematous (red) skin with blisters that burst to reveal raw areas or erosions. These red areas later become brownish in color and the scaling appears on areas exposed to sunlight. This dermatitis has a clear demarcation between the affected and the unaffected areas.
2. In the second stage of pellagroderma, the skin becomes dry, rough, hard, and cracks somewhat resembling goose skin. It is also scaly and hyperpigmented.
3. As the disease progresses, the skin becomes drier, harder, scalier and more cracked. It may also be covered with a blackish crusts from the bleeding cracks.
These pellagroderma lesions are symmetrical (affect both sides of the body) such as the face, neck (Casal’s necklace on dermatome C3 and C4), forearms and hands (pellagrous glove) as well as the legs and feet (pellagrous boot). There may be an associated painful, burning sensation.
The lips, tongue, and gums can also begin peeling as the mucous membranes become inflammed and the patient develops pain in the mouth. The vagina and urethra can also be affected.
Patients who develop recurrent pellagra develop blisters in the same site (pemphigus pellagrosus).
Symptoms of plantar warts include rough, flesh colored, hyperkeratotic (scaly) papules which may be single or multiple.
These swellings are usually painless but they may become painful if they are on areas that receive much pressure when walking or standing such as over the heads of the metatarsals and the heel.
Symptoms of plantar xerosis include skin on the feet which is dry, rough, flaky and peeling.
Symptoms of poikiloderma include mottled hyperpigmentation (dark discoloration), hypopigmentation (light discoloration) and atrophy (thinning skin) with telangiectases (dilated capillaries).
Symptoms of pyogenic granuloma include a swelling which arises suddenly, bleeds easily and grows quickly.
Sun poisoning is a term which is used to refer to 1. Severe sunburns 2. Polymorphous light eruption (PMLE) and 3. Solar urticaria.
Symptoms of sunburns include redness of the skin and discomfort or pain. Blisters and swelling are present in severe sunburns.
Symptoms of tinea versicolor include several round to oval macules and patches that can coalesce to involve large areas like the entire back since many persons are not aware of them.
These patches which do not tan, are usually hypopigmented or whitish in persons with dark skin and salmon or pink colored in persons with light skin.
Regardless of their color, these areas have a very fine scale which may not be apparent unless the patch is scratched.
Symptoms of traction alopecia include gradual and painless localized hair loss with bald patches which are usually along the hair line.
There may also be associated headaches and pain on the scalp due to the tight hairstyles but not due to the traction alopecia.
Symptoms of urticaria can develop within minutes to hours of coming in contact with the causative allergen. These symptoms include intensely pruritic (itchy), elevated, well-circumscribed papules and plaques (swellings) with localized edema (swelling).
This localized edema results in lesions which are palpable lesion. The lesions of urticaria are erythematous (red) though they can be flesh colored in dark skinned people. Urticarial lesions are also non-scaly and they blanch completely when pressure is applied to them.
Though they are usually separated by normal skin, urticarial lesions can coalesce and cover large areas of the body. They are also migratory since they can move from one part of the body to another and involve the skin on any part of the body. These lesion can take on many forms such as linear, circular, or arcuate (serpiginous).
Symptoms of vitiligo include patches of skin which have lost their normal skin color and become lighter than the surrounding areas. Despite the color changes, these white spots on the skin are usually not itchy or scaly.
Sun exposed areas such as the face, hands and feet are usually the first ones to begin losing their normal color.
Other commonly affected areas include the mouth, armpits and genital organs. Vitiligo may also develop at the sites of trauma such as cuts or burns. This is called the Koebner phenomenon.
Other vitiligo symptoms that may develop include premature graying of the scalp hair, eyebrows and beard. The areas affected by vitiligo may also be noted to have increased sweating.
Though it is physically limited to the skin, vitiligo also causes effects which are more than just skin deep. These psychological effects which include emotional stress, social anxiety, low self esteem and depression, are more likely to develop in adolescents with vitiliginous patches on their faces, hands and genital organs.
Symptoms of xanthelasma include a painless, soft, yellowish swelling on the eyelid.
