Dermatology
Dermatology is the branch of medicine dealing with the skin.''Random House Webster's Unabridged Dictionary.'' Random House, Inc. 2001. Page 537. . It is a speciality with both medical and surgical aspects. A dermatologist is a specialist medical doctor who manages diseases related to skin, hair, nails, and some cosmetic problems. Etymology Attested in English in 1819, the word "dermatology" derives from the Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία '' -logia''. Neo-Latin ''dermatologia'' was coined in 1630, an anatomical term with various French and German uses attested from the 1730s. History In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases ( Alibert's, 1806–1816) appeared in print around the same time.Freedberg, et al.

Erythema
Erythema (from the Greek , meaning red) is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. It occurs with any skin injury, infection, or inflammation. Examples of erythema not associated with pathology include nervous blushes. Types * Erythema ab igne * Erythema chronicum migrans * Erythema induratum * Erythema infectiosum (or fifth disease) * Erythema marginatum * Erythema migrans * Erythema multiforme (EM) * Erythema nodosum * Erythema toxicum * Erythema elevatum diutinum * Erythema gyratum repens * Keratolytic winter erythema * Palmar erythema Causes It can be caused by infection, massage, electrical treatment, acne medication, allergies, exercise, solar radiation (sunburn), photosensitization, acute radiation syndrome, mercury toxicity, blister agents, niacin administration, or waxing and tweezing of the hairs—any of which can cause the capillaries to dilate, resulting in redness.

Erythema Marginatum
Erythema marginatum is a type of erythema (redness of the skin or mucous membranes) involving pink rings on the torso and inner surfaces of the limb (anatomy), limbs which come and go for as long as several months. It is found primarily on extensor surfaces. An association with bradykinin has been proposed in the case of hereditary angioedema. Presentation The rings are barely raised and are non-pruritus, itchy. The face is generally spared. Associated conditions It occurs in less than 5% of patients with rheumatic fever, but is considered a major Rheumatic fever#Diagnosis, Jones criterion when it does occur. The four other major criteria include carditis, polyarthritis, Sydenham's chorea, and subcutaneous nodules. In this case, it is often associated with Group A streptococcal infection, otherwise known as ''Streptococcus pyogenes'' infection, which can be detected with an ASO titer. It is an early feature of rheumatic fever and not pathognomonic of it. It may be associated wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erythema Annulare Centrifugum
Erythema annulare centrifugum (EAC), is a descriptive term for a class of skin lesion presenting redness (erythema) in a ring form (''anulare'') that spreads from a center (''centrifugum''). It was first described by Darier in 1916.J. Darier. De l’érythème annulaire centrifuge (érythème papulo-circineé migrateuse et chronique) et de quelques éruptions analogues. Annales de dermatologie et de syphilographie, Paris, 1916-1917, 5: 57-58. Many different terms have been used to classify these types of lesions and it is still controversial on what exactly defines EAC. Some of the types include annular erythema (deep and superficial), erythema perstans, erythema gyratum perstans, erythema gyratum repens, darier erythema (deep gyrate erythema) and erythema figuratum perstans. Symptoms Occurring at any age these lesions appear as raised pink-red ring or bulls-eye marks. They range in size from . The lesions sometimes increase size and spread over time and may not be complete rings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
