General skin conditions refer to the most common dermatological problems that can affect any and all areas of the body.
Insect bites are quite common, especially at certain times of the year, and are one of the most frequent causes of dermatitis.
Speaking of a jellyfish sting isn’t technically correct, as jellyfish don’t have stingers. Instead, it is the cells in their tentacles that sting. Jellyfish tentacles are both defensive tools and powerful weapons, and are lined with special cnidocyte cells which inject a stinging liquid into a jellyfish’s prey.
Psoriasis is a type of dermatitis which causes the epidermis to thicken, resulting in inflamed and itchy plaques of skin. It is an unpredictable, complex skin condition that affects all ages and can appear anywhere on the body.
Psoriasis can occur in very visible areas such as on the face, along the hairline or on the hands, causing some individuals significant psychological discomfort.
Pityriasis rosea is an infectious exanthem most likely caused by the herpes VI-VII viruses on the skin. Unlike other rashes, pityriasis rosea is not contagious and does not require specific treatment. The condition usually lasts an average of one to two months and often disappears on its own, but often recurs even years later.
TINEA VERSICOLOR(PITYRIASIS VERSICOLOR)
Tinea versicolor is a yeast infection caused by the overproduction of the malassezia (formerly pityrosporum) fungus.
Solar erythema is inflammation caused by excessive exposure to sunlight or UV lamps. It causes the appearance of red patches on the sun-exposed skin and, in some cases, peeling (desquamation).
Shingles is a viral disease that usually affects older adults and is caused by the varicella zoster virus. Shingles causes clusters of blisters to erupt in a strip or band on one side of the body.
Lichen planus is a rare, recurrent inflammatory dermatitis. It causes the formation of many itchy bumps that can spread all over the body.
Skin ulcers are as common as they are disabling. Ulcers can form on any area of the body where the blood vessels cannot properly nourish the skin.
Wounds are lesions of the stratum corneum and can be superficial (abrasions and grazes), or deep (e.g. cuts). Bleeding may accompany wounds depending on their severity. Wounds can be caused accidentally in cases of trauma, or following surgical procedures. The most common wounds occur after accidents involving sharp, pointed objects at home or work.
Ichthyosis is a genetic disorder that alters the way in which the stratum corneum develops. The name comes from the Greek root for “fish” due to the dry, scaly skin that is a defining feature of the condition.
Vitiligo is a skin pigmentation disorder that triggers the deactivation or disappearance of the melanin-producing cells (melanocytes), causing white patches to form in the affected area.
