A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment.
A papule is a small, well-defined bump in the skin. It may have a rounded, pointed or flat top, and may have a dip. It can appear with a stalk, be thread-like or look warty. It can be soft or firm and its surface may be rough or smooth. Some have crusts or scales. A papule can be flesh colored, yellow, white, brown, red, blue or purplish. There may be just one or many, and they may occur irregularly in different parts of the body or appear in clusters. It does not contain fluid but may progress to a pustule or vesicle. A papule is smaller than a nodule; it can be as tiny as a pinhead and is typically less than 1 cm in width, according to some sources, and 0.5 cm according to others. When merged together, it appears as a plaque.
Diabetic dermopathy is a type of skin lesion usually seen in people with diabetes mellitus. It is characterized by dull-red papules that progress to well-circumscribed, small, round, atrophic hyperpigmented skin lesions usually on the shins. It is the most common of several diabetic skin conditions, being found in up to 30% of diabetics. Similar lesions can occasionally be found in non-diabetics usually following trauma or injury to the area; however, more than 4 lesions strongly suggests diabetes.
Tinea faciei is a fungal infection of the skin of the face. It generally appears as a photosensitive painless red rash with small bumps and a raised edge appearing to grow outwards, usually over eyebrows or one side of the face. It may feel wet or have some crusting, and overlying hairs may fall out easily. There may be a mild itch.
Idiopathic guttate hypomelanosis is characterised by multiple small whitish flat spots. They are typically irregular, well defined and frequently appear on the arms, legs and face of older people.
The Asboe-Hansen sign refers to the extension of a large blister to adjacent unblistered skin when pressure is put on the top of it. It is seen along with Nikolsky's sign, both used to assess the severity of some blistering diseases such as pemphigus vulgaris and severe bullous drug reactions.
Prurigo gestationis is an eruption consisting of pruritic, excoriated papules of the proximal limbs and upper trunk, most often occurring between the 20th and 34th week of gestation.
Erythema gyratum repens is a skin condition that has a strong association with internal cancers. It characteristically presents with red wavy lines, generally in older adults. These regular whirly rings rapidly and repetitively appear within existing ones, giving the impression that the rash is moving. The resulting pattern is similar to wood grain. There is often an intense itch and scale over the leading edge, which may be slightly raised.
Id reactions are types of acute dermatitis developing after days or weeks at skin locations distant from the initial inflammatory or infectious site. They can be localised or generalised. This is also known as an 'autoeczematous response' and there must be an identifiable initial inflammatory or infectious skin problem which leads to the generalised eczema. Often intensely itchy, the red papules and pustules can also be associated with blisters and scales and are always remote from the primary lesion. It is most commonly a blistering rash with itchy vesicles on the sides of fingers and feet as a reaction to fungal infection on the feet, athlete's foot. Stasis dermatitis, allergic contact dermatitis, acute irritant contact eczema and infective dermatitis have been documented as possible triggers, but the exact cause and mechanism is not fully understood. Several other types of id reactions exist including erythema nodosum, erythema multiforme, Sweet's syndrome and urticaria.
Anonychia is the failure to form fingernails or toenails.
Onychoschizia, also known as nail splitting and brittle nails, is a splitting of the free-edged tip of the nail. There is also often a longitudinal split in addition to the separation of keratin layers.
Follicular atrophoderma is a skin condition consisting of follicular indentations without hairs, notably occurring on extensor surfaces of the hands, legs and arms.
Nevus spilus, also known as speckled lentiginous nevus, is a light brown or tan birth mark, speckled with small, dark spots or small bumps. If it occurs in a segmental pattern then it is sometimes referred to as a Zosteriform speckled lentiginous nevus.
Lipoatrophia annularis is a skin condition affecting primarily women, characterized by the loss of subcutaneous fat in the upper extremity.
Arterial insufficiency ulcers are mostly located on the lateral surface of the ankle or the distal digits. They are commonly caused by peripheral artery disease (PAD).
Larva currens, is an itchy skin condition caused by infections with Strongyloides stercoralis.
A diabetic bulla is a cutaneous condition characterized by a noninflammatory, spontaneous, painless blister, often in acral locations, seen in diabetic patients.
Waxy skin is a cutaneous condition observed in roughly 50% of diabetic patients with longstanding disease.
Diabetic cheiroarthropathy, also known as Diabetic stiff hand syndrome or limited joint mobility syndrome, is a cutaneous condition characterized by waxy, thickened skin and limited joint mobility of the hands and fingers, leading to flexion contractures, a condition associated with diabetes mellitus and it is observed in roughly 30% of diabetic patients with longstanding disease. It can be a predictor for other diabetes-related complications and was one of the earliest known complications of diabetes, first documented in 1974.
