Majocchi's Disease

	Majocchi's Disease Majocchi's disease, also known as Purpura annularis telangiectodes of Majocchi is a not-well-recognized and uncommon skin condition characterized by purple/bluish-red 1- to 3-cm annular patches composed of dark red telangiectases with petechiae. It is one of a group of disorders referred to as pigmented purpuric dermatosis that all occur as a result of vascular inflammation and pigment deposition. Treatment Majocchi's disease is a chronic condition for which there is no cure. It often follows a recurrent course of alternating improvement and flares. There are treatments available to help improve the symptoms for some individuals, but responses vary. Some of these treatments include the application of topical steroids and ultraviolet therapy. The use of narrowband UVB and psoralen Psoralen (also called psoralene) is the parent compound in a family of naturally occurring organic compounds known as the linear furanocoumarins. It is structurally related to coumarin by the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Telangiectases Telangiectasias, also known as spider veins, are small dilated blood vessels that can occur near the surface of the skin or mucous membranes, measuring between 0.5 and 1 millimeter in diameter. These dilated blood vessels can develop anywhere on the body, but are commonly seen on the face around the nose, cheeks and chin. Dilated blood vessels can also develop on the legs, although when they occur on the legs, they often have underlying venous reflux or "hidden varicose veins" (see #Venous hypertension, Venous hypertension section below). When found on the legs, they are found specifically on the upper thigh, below the knee joint and around the ankles. Many patients with spider veins seek the assistance of physicians who specialize in vein care or peripheral vascular disease. These physicians are called vascular surgeons or phlebologists. More recently, interventional radiologists have started treating venous problems. Some telangiectasias are due to developmental abnormalities t ...

	Petechiae A petechia () is a small red or purple spot (≤4 mm in diameter) that can appear on the skin, conjunctiva, retina, and mucous membranes which is caused by haemorrhage of capillaries. The word is derived from Italian , 'freckle,' of obscure origin. It refers to one of the three descriptive types of hematoma differentiated by size, the other two being ecchymosis (>1cm in diameter) and purpura (4-10mm in diameter). The term is always used in the plural (petechiae), since a single petechia is seldom noticed or significant. Causes Physical trauma The most common cause of petechiae is through physical trauma such as a hard bout of coughing, holding breath, vomiting, or crying, which can result in facial petechiae, especially around the eyes. Such instances are harmless and usually disappear within a few days. * Constriction, asphyxiation – petechiae, especially in the eyes, may also occur when excessive pressure is applied to tissue (e.g., when a tourniquet is applied to an extremity ...

	Pigmented Purpuric Dermatosis Pigmented purpuric dermatosis refers to one of the three major classes of skin conditions characterized by purpuric skin eruptions. Pigmented purpuric dermatosis are distinguished from other purpura by size (0.3–1 cm) and are most often seen in the lower extremities. Pigmentary purpuric eruptions may present with one of several clinical patterns. There may be overlapping characteristics among pigmented purpuric dermatosis and between their signs and those of other purpuric eruptions. Examples of the pigmented purpuric dermatosis group include: :* Schamberg's disease :* Majocchi's disease (Purpura annularis telangiectodes) :* Gougerot-Blum syndrome (Pigmented purpuric lichenoid dermatitis) :* Ducas and Kapetanakis pigmented purpura :* Lichen aureus Although vascular damage may be present, it is insufficient for these conditions to be considered forms of vasculitis. A few very small non-blinded studies of treatment with narrow-band ultraviolet light have been reporte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Psoralen And Ultraviolet A Therapy PUVA (psoralen and UVA) is an ultraviolet light therapy treatment for skin diseases: eczema, psoriasis, graft-versus-host disease, vitiligo, mycosis fungoides, large plaque parapsoriasis, and cutaneous T-cell lymphoma, using the sensitizing effects of the drug psoralen. The psoralen is applied or taken orally to sensitize the skin, then the skin is exposed to UVA. Photodynamic therapy is the general use of nontoxic light-sensitive compounds that are exposed selectively to light, whereupon they become toxic to targeted malignant and other diseased cells. Still, PUVA therapy is often classified as a separate technique from photodynamic therapy. Procedure Psoralens are materials that make the skin more sensitive to UV light. They are photosensitizing agents found in plants naturally and manufactured synthetically. Psoralens are taken as pills (systemically) or can be applied directly to the skin, by soaking the skin in a solution that contains the psoralens. They allow UVA energy to ...
