Dermatitis Repens
Dermatitis repens (also known as Acrodermatitis continua, Acrodermatitis perstans, Pustular acrodermatitis, Acrodermatitis continua of Hallopeau, Acrodermatitis continua suppurativa Hallopeau, Hallopeau's acrodermatitis, Hallopeau's acrodermatitis continua, and Dermatitis repens Crocker) is a rare, sterile, pustular eruption of the fingers and toes that slowly extends proximally.Freedberg, et al.

List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying m ...

François Henri Hallopeau
__NOTOC__ François Henri Hallopeau (17 January 1842, Paris – 20 March 1919, Paris) was a French dermatologist. He studied medicine under Alfred Vulpian and Sigismond Jaccoud. He co-founded and was secretary general of the ''Société Française de dermatologie et de syphiligraphie''. He became a member of the ''Académie de Médecine'' in 1893. He coined the medical term ''trichotillomania'' in 1889. He also coined the word ''antibiotique'' in 1871 to describe a substance opposed to the development of life. Selman Waksman was later credited with coining the word ''antibiotic'' to describe such compounds that were derived from other living organisms, such as penicillin.

Psoriasis
Psoriasis is a long-lasting, noncontagious autoimmune disease characterized by raised areas of abnormal skin. These areas are red, pink, or purple, dry, itchy, and scaly. Psoriasis varies in severity from small, localized patches to complete body coverage. Injury to the skin can trigger psoriatic skin changes at that spot, which is known as the Koebner phenomenon. The five main types of psoriasis are plaque, guttate, inverse, pustular, and erythrodermic. Plaque psoriasis, also known as psoriasis vulgaris, makes up about 90% of cases. It typically presents as red patches with white scales on top. Areas of the body most commonly affected are the back of the forearms, shins, navel area, and scalp. Guttate psoriasis has drop-shaped lesions. Pustular psoriasis presents as small, noninfectious, pus-filled blisters. Inverse psoriasis forms red patches in skin folds. Erythrodermic psoriasis occurs when the rash becomes very widespread, and can develop from any of the other type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skin Lesion
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. Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology ( chronic blistering conditions), cause (skin conditions ...
