The diagnosis is frequently made by treating the initial triggering skin problem and observing the improvement in the eczematous rash. Both the initial skin problem and the id reaction must be observed to make the diagnosis. [5] [6] Not all dyshidrotic rashes are id reactions, but id reactions are often dyshidrotic-like. [2]
In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm that forms the dermis and subcutaneous tissues. [ 5 ] [ 6 ] [ 7 ] The epidermis is the most superficial layer of skin, a squamous epithelium with several strata : the stratum corneum , stratum lucidum , stratum ...
An exanthem is a widespread rash occurring on the outside of the body and usually occurring in children. [1] It is usually caused by a virus, [2] but an exanthem can be caused by bacteria, [3] toxins, drugs, other microorganisms, or as the result from autoimmune disease.
A rash is a change of the skin that affects its color, appearance, or texture. A rash may be localized in one part of the body, or affect all the skin. Rashes may cause the skin to change color, itch, become warm, bumpy, chapped, dry, cracked or blistered, swell, and may be painful. The causes, and therefore treatments for rashes, vary widely.
Dukes' disease, named after Clement Dukes (1845–1925), [1] [2] also known as fourth disease, [3] Filatov-Dukes' disease (after Nil Filatov), [4] Staphylococcal Scalded Skin Syndrome (SSSS), [5] or Ritter's disease [6] is an exanthem (rash-causing) illness primarily affecting children and historically described as a distinct bacterial infection, though its existence as a separate disease ...
Hives, or urticaria, is a form of skin rash with red, raised, itchy bumps. [1] They may also burn or sting. [2] Hives can appear anywhere on the surface of the skin. Whether the trigger is allergic or not, a complex release of inflammatory mediators, including histamine from cutaneous mast cells, results in fluid leakage from superficial blood ...
Tinea is often called "ringworm" because the rash is circular, with a ring-like appearance. It is sometimes equated with dermatophytosis , and, while most conditions identified as "tinea" are members of the imperfect fungi that make up the dermatophytes , conditions such as tinea nigra and tinea versicolor are not caused by dermatophytes.
The disease manifests in many forms, making the diagnosis difficult, but the most common features of this disease involve the skin, joints, and central nervous system. All have a maculopapular urticarial skin rash that is often present at birth (75% cases). It is probably more correctly described as an urticarial-like rash.
