Foot Dermatoses
Skin diseases of the foot, general or unspecified.
Foot
Hand Dermatoses
Hand dermatoses is a general term referring to various inflammatory skin conditions primarily affecting the hands, such as eczema, psoriasis, and contact dermatitis, characterized by erythema, scaling, vesiculation, fissuring, or lichenification.
Facial Dermatoses
Facial dermatoses refers to various skin conditions that affect the face, causing symptoms such as redness, inflammation, papules, pustules, scaling, or pigmentation changes, which can be caused by a range of factors including genetics, infections, allergies, and environmental factors.
Skin Diseases
'Skin diseases' is a broad term for various conditions affecting the skin, including inflammatory disorders, infections, benign and malignant tumors, congenital abnormalities, and degenerative diseases, which can cause symptoms such as rashes, discoloration, eruptions, lesions, itching, or pain.
Skin Diseases, Vesiculobullous
Skin diseases characterized by local or general distributions of blisters. They are classified according to the site and mode of blister formation. Lesions can appear spontaneously or be precipitated by infection, trauma, or sunlight. Etiologies include immunologic and genetic factors. (From Scientific American Medicine, 1990)
Linear IgA Bullous Dermatosis
Autoimmune disease characterized by subepidermal blisters and linear deposition of autoantibodies at the dermoepidermal junction. The accumulated autoantibodies are of IMMUNOGLOBULIN A and occasionally IMMUNOGLOBULIN G classes against epidermal BASEMENT MEMBRANE proteins. The dermatosis is sometimes associated with malignancies and use of certain drugs (e.g., VANCOMYCIN).
Sweet Syndrome
Condition characterized by large, rapidly extending, erythematous, tender plaques on the upper body usually accompanied by fever and dermal infiltration of neutrophilic leukocytes. It occurs mostly in middle-aged women, is often preceded by an upper respiratory infection, and clinically resembles ERYTHEMA MULTIFORME. Sweet syndrome is associated with LEUKEMIA.
Dermatitis, Occupational
A recurrent contact dermatitis caused by substances found in the work place.
Foot Diseases
Anatomical and functional disorders affecting the foot.
Diabetic Foot
Common foot problems in persons with DIABETES MELLITUS, caused by any combination of factors such as DIABETIC NEUROPATHIES; PERIPHERAL VASCULAR DISEASES; and INFECTION. With the loss of sensation and poor circulation, injuries and infections often lead to severe foot ulceration, GANGRENE and AMPUTATION.
Leg Dermatoses
Scalp Dermatoses
Scalp dermatoses refer to various inflammatory skin conditions affecting the scalp, including seborrheic dermatitis, psoriasis, atopic dermatitis, and tinea capitis, often characterized by symptoms such as redness, scaling, itching, and hair loss.
Foot Deformities, Acquired
Foot Ulcer
Erythema
Redness of the skin produced by congestion of the capillaries. This condition may result from a variety of causes.
Pyoderma Gangrenosum
An idiopathic, rapidly evolving, and severely debilitating disease occurring most commonly in association with chronic ulcerative colitis. It is characterized by the presence of boggy, purplish ulcers with undermined borders, appearing mostly on the legs. The majority of cases are in people between 40 and 60 years old. Its etiology is unknown.
Foot Injuries
General or unspecified injuries involving the foot.
Hyperpigmentation
Excessive pigmentation of the skin, usually as a result of increased epidermal or dermal melanin pigmentation, hypermelanosis. Hyperpigmentation can be localized or generalized. The condition may arise from exposure to light, chemicals or other substances, or from a primary metabolic imbalance.
Foot Deformities
Alterations or deviations from normal shape or size which result in a disfigurement of the foot.
Neurodermatitis
An extremely variable eczematous skin disease that is presumed to be a response to prolonged vigorous scratching, rubbing, or pinching to relieve intense pruritus. It varies in intensity, severity, course, and morphologic expression in different individuals. Neurodermatitis is believed by some to be psychogenic. The circumscribed or localized form is often referred to as lichen simplex chronicus.
Dapsone
A sulfone active against a wide range of bacteria but mainly employed for its actions against MYCOBACTERIUM LEPRAE. Its mechanism of action is probably similar to that of the SULFONAMIDES which involves inhibition of folic acid synthesis in susceptible organisms. It is also used with PYRIMETHAMINE in the treatment of malaria. (From Martindale, The Extra Pharmacopoeia, 30th ed, p157-8)
Dermatitis
Any inflammation of the skin.
Foot Bones
The TARSAL BONES; METATARSAL BONES; and PHALANGES OF TOES. The tarsal bones consists of seven bones: CALCANEUS; TALUS; cuboid; navicular; internal; middle; and external cuneiform bones. The five metatarsal bones are numbered one through five, running medial to lateral. There are 14 phalanges in each foot, the great toe has two while the other toes have three each.
Pruritus
An intense itching sensation that produces the urge to rub or scratch the skin to obtain relief.
Pigmentation Disorders
Pigmentation disorders are conditions that affect the production or distribution of melanin, the pigment responsible for skin, hair, and eye color, leading to changes in the color of these bodily features.
Purpura
Hypopigmentation
A condition caused by a deficiency or a loss of melanin pigmentation in the epidermis, also known as hypomelanosis. Hypopigmentation can be localized or generalized, and may result from genetic defects, trauma, inflammation, or infections.
Acantholysis
Eczema
A pruritic papulovesicular dermatitis occurring as a reaction to many endogenous and exogenous agents (Dorland, 27th ed).
Pyoderma
Any purulent skin disease (Dorland, 27th ed).
Lichen Planus
An inflammatory, pruritic disease of the skin and mucous membranes, which can be either generalized or localized. It is characterized by distinctive purplish, flat-topped papules having a predilection for the trunk and flexor surfaces. The lesions may be discrete or coalesce to form plaques. Histologically, there is a "saw-tooth" pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal inflammatory infiltrate composed predominantly of T-cells. Etiology is unknown.
Foot Joints
Dermatitis, Exfoliative
The widespread involvement of the skin by a scaly, erythematous dermatitis occurring either as a secondary or reactive process to an underlying cutaneous disorder (e.g., atopic dermatitis, psoriasis, etc.), or as a primary or idiopathic disease. It is often associated with the loss of hair and nails, hyperkeratosis of the palms and soles, and pruritus. (From Dorland, 27th ed)
Foot Deformities, Congenital
Alterations or deviations from normal shape or size which result in a disfigurement of the foot occurring at or before birth.
Skin Care
Maintenance of the hygienic state of the skin under optimal conditions of cleanliness and comfort. Effective in skin care are proper washing, bathing, cleansing, and the use of soaps, detergents, oils, etc. In various disease states, therapeutic and protective solutions and ointments are useful. The care of the skin is particularly important in various occupations, in exposure to sunlight, in neonates, and in PRESSURE ULCER.
Dermatitis Herpetiformis
Rare, chronic, papulo-vesicular disease characterized by an intensely pruritic eruption consisting of various combinations of symmetrical, erythematous, papular, vesicular, or bullous lesions. The disease is strongly associated with the presence of HLA-B8 and HLA-DR3 antigens. A variety of different autoantibodies has been detected in small numbers in patients with dermatitis herpetiformis.
Skin Diseases, Papulosquamous
Keratolytic Agents
Agents that soften, separate, and cause desquamation of the cornified epithelium or horny layer of skin. They are used to expose mycelia of infecting fungi or to treat corns, warts, and certain other skin diseases.
Patch Tests
Scabies
Skin
Dermatitis, Allergic Contact
A contact dermatitis due to allergic sensitization to various substances. These substances subsequently produce inflammatory reactions in the skin of those who have acquired hypersensitivity to them as a result of prior exposure.
Paraneoplastic Syndromes
Chemexfoliation
Application of a cauterant to the skin for the purpose of causing a superficial destruction of the epidermis and upper layers of the dermis. After healing, the treated area has new epithelium.
Parapsoriasis
The term applied to a group of relatively uncommon inflammatory, maculopapular, scaly eruptions of unknown etiology and resistant to conventional treatment. Eruptions are both psoriatic and lichenoid in appearance, but the diseases are distinct from psoriasis, lichen planus, or other recognized dermatoses. Proposed nomenclature divides parapsoriasis into two distinct subgroups, PITYRIASIS LICHENOIDES and parapsoriasis en plaques (small- and large-plaque parapsoriasis).
Hair Preparations
Acitretin
Agricultural Workers' Diseases
Diseases in persons engaged in cultivating and tilling soil, growing plants, harvesting crops, raising livestock, or otherwise engaged in husbandry and farming. The diseases are not restricted to farmers in the sense of those who perform conventional farm chores: the heading applies also to those engaged in the individual activities named above, as in those only gathering harvest or in those only dusting crops.
Hand, Foot and Mouth Disease
Fluorescent Antibody Technique, Direct
Dermatitis, Atopic
A chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. It is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. In infants it is known as infantile eczema.
Vulvitis
Inflammation of the VULVA. It is characterized by PRURITUS and painful urination.
Vulvar Lichen Sclerosus
Ultraviolet Therapy
The use of ultraviolet electromagnetic radiation in the treatment of disease, usually of the skin. This is the part of the sun's spectrum that causes sunburn and tanning. Ultraviolet A, used in PUVA, is closer to visible light and less damaging than Ultraviolet B, which is ionizing.
Skin Diseases, Genetic
Diseases of the skin with a genetic component, usually the result of various inborn errors of metabolism.
Flatfoot
A condition in which one or more of the arches of the foot have flattened out.
Rosacea
A cutaneous disorder primarily of convexities of the central part of the FACE, such as FOREHEAD; CHEEK; NOSE; and CHIN. It is characterized by FLUSHING; ERYTHEMA; EDEMA; RHINOPHYMA; papules; and ocular symptoms. It may occur at any age but typically after age 30. There are various subtypes of rosacea: erythematotelangiectatic, papulopustular, phymatous, and ocular (National Rosacea Society's Expert Committee on the Classification and Staging of Rosacea, J Am Acad Dermatol 2002; 46:584-7).
Acrodermatitis
Inflammation involving the skin of the extremities, especially the hands and feet. Several forms are known, some idiopathic and some hereditary. The infantile form is called Gianotti-Crosti syndrome.
Pemphigoid, Bullous
A chronic and relatively benign subepidermal blistering disease usually of the elderly and without histopathologic acantholysis.
Acanthosis Nigricans
Pemphigoid Gestationis
An itching, autoimmune, bullous SKIN disease that occurs during the last two trimesters of PREGNANCY and PUERPERIUM. It also affects non-pregnant females with tissue of PLACENTA origin, such as CHORIOCARCINOMA; or HYDATIDIFORM MOLE. It exhibits antigenic and clinical similarity to bullous pemphigoid (PEMPHIGOID, BULLOUS). This disease does not involve herpes viruses (old name, herpes gestationis).
Dermatitis, Contact
Pemphigus
Group of chronic blistering diseases characterized histologically by ACANTHOLYSIS and blister formation within the EPIDERMIS.
