Inverse Psoriasis
Inverse psoriasis or flexural psoriasis is a form of psoriasis that selectively, and often exclusively, involves the folds, recesses, and flexor surfaces such as the ears, axillae, groin folds, inframammary folds, navel, intergluteal cleft, penis, and lips.James, William; Berger, Timothy; Elston, Dirk (2005).

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 ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axilla
The axilla (also, armpit, underarm or oxter) is the area on the human body directly under the shoulder joint. It includes the axillary space, an anatomical space within the shoulder girdle between the arm and the thoracic cage, bounded superiorly by the imaginary plane between the superior borders of the first rib, clavicle and scapula (above which are considered part of the neck), medially by the serratus anterior muscle and thoracolumbar fascia, anteriorly by the pectoral muscles and posteriorly by the subscapularis, teres major and latissimus dorsi muscle. The soft skin covering the lateral axilla contains many hair and sweat glands. In humans, the formation of body odor happens mostly in the axilla. These odorant substances have been suggested by some to serve as pheromones, which play a role related to mate selection, although this is a controversial topic within the scientific community. The underarms seem more important than the pubic area for emitting body odor, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inguinal Folds
In human anatomy, the inguinal region refers to either the groin or the lower lateral regions of the abdomen. It may also refer to: * Conjoint tendon, previously known as the inguinal aponeurotic falx, a structure formed from the transversus abdominis insertion into the pecten pubis * Granuloma inguinale, a bacterial disease characterized by ulcerative genital lesions that is endemic in many less developed regions * Inguinal canal, a passage in the anterior abdominal wall which in men conveys the spermatic cord and in women the round ligament * Inguinal falx, the conjoined tendon of the obliquus internus and transversus muscles * Inguinal hernia, a protrusion of abdominal-cavity contents through the inguinal canal ** Direct inguinal hernia, a type of inguinal hernia with a sac that is medial to the inferior epigastric vessels ** Indirect inguinal hernia, a hernia that results from the failure of the embryonic internal inguinal ring after the testicle has passed through it * Inguina ...

Inframammary Fold
In human anatomy, the inframammary fold (IMF), inframammary crease or inframammary line is the natural lower boundary of the breast, the place where the breast and the chest meet. The choice of the term depends on the prominence of the feature. It is also sometimes called the inframammary ligament. From the cosmetological point of view, it is an important aesthetic component of the breast which should be taken into consideration during various kinds of breast surgery. Histologically, the inframammary fold is an intrinsic dermal structure consisting of regular arrays of collagen held in place by a specialized superficial fascia system. The fold is formed by the fusion of the superficial and mammary fascia A fascia (; plural fasciae or fascias; adjective fascial; from Latin: "band") is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches to, stabilizes, encloses, and separates muscles and other internal organs ...e.

Navel
The navel (clinically known as the umbilicus, commonly known as the belly button or tummy button) is a protruding, flat, or hollowed area on the abdomen at the attachment site of the umbilical cord. All placental mammals have a navel, although it is generally more conspicuous in humans. Structure The umbilicus is used to visually separate the abdomen into quadrants. The umbilicus is a prominent scar on the abdomen, with its position being relatively consistent among humans. The skin around the waist at the level of the umbilicus is supplied by the tenth thoracic spinal nerve (T10 dermatome). The umbilicus itself typically lies at a vertical level corresponding to the junction between the L3 and L4 vertebrae, with a normal variation among people between the L3 and L5 vertebrae. Parts of the adult navel include the "umbilical cord remnant" or "umbilical tip", which is the often protruding scar left by the detachment of the umbilical cord. This is located in the center ...

Intergluteal Cleft
The intergluteal cleft or just gluteal cleft, also known by a number of synonyms, including natal cleft, butt crack, and cluneal cleft, is the groove between the buttocks that runs from just below the sacrum to the perineum, so named because it forms the visible border between the external rounded protrusions of the gluteus maximus muscles. Other names are the ''anal cleft'', ''crena analis'', ''crena interglutealis'', and ''rima ani''. Colloquially the intergluteal cleft is known as ''bum crack'' (UK) or ''butt crack'' (US). The intergluteal cleft is located superior to the anus. There are several disorders that can affect the intergluteal cleft including inverse psoriasis, caudal regression syndrome, and pilonidal disease. See also * Buttock cleavage * Rectum *Anal canal * * *Anatomical terms of location Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans.

Penis
A penis (plural ''penises'' or ''penes'' () is the primary sexual organ that male animals use to inseminate females (or hermaphrodites) during copulation. Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species, and in those species in which the male does bear a so-called penis, the penises in the various species are not necessarily homologous. The term ''penis'' applies to many intromittent organs, but not to all. As an example, the intromittent organ of most cephalopoda is the hectocotylus, a specialized arm, and male spiders use their pedipalps. Even within the Vertebrata there are morphological variants with specific terminology, such as hemipenes. In most species of animals in which there is an organ that might reasonably be described as a penis, it has no major function other than intromission, or at least conveying the sperm to the female, but in the placental mammals the penis bears the ...

Seborrheic Dermatitis
Seborrhoeic dermatitis, sometimes inaccurately referred to as seborrhoea, is a long-term skin disorder. Symptoms include red, scaly, greasy, itchy, and inflamed skin. Areas of the skin rich in oil-producing glands are often affected including the scalp, face, and chest. It can result in social or self-esteem problems. In babies, when the scalp is primarily involved, it is called cradle cap. Dandruff is a milder form of the condition without inflammation. The cause is unclear but believed to involve a number of genetic and environmental factors. Risk factors include poor immune function, Parkinson's disease, and alcoholic pancreatitis. The condition may worsen with stress or during the winter. The '' Malassezia'' yeast is believed to play a role. It is not a result of poor hygiene. Diagnosis is typically based on the symptoms. The condition is not contagious. The typical treatment is antifungal cream and anti-inflammatory agents. Specifically, ketoconazole or ciclopirox are eff ...

Intertrigo
Intertrigo refers to a type of inflammatory rash (dermatitis) of the superficial skin that occurs within a person's body folds. These areas are more susceptible to irritation and subsequent infection due to factors that promote skin breakdown such as moisture, friction, and exposure to bodily secretions and excreta such as sweat, urine, or feces. Areas of the body which are more likely to be affected by intertrigo include the inframammary fold, intergluteal cleft, armpits, and spaces between the fingers or toes. Skin affected by intertrigo is more prone to infection than intact skin. The term "intertrigo" commonly refers to a secondary infection with bacteria (such as ''Corynebacterium minutissimum''), fungi (such as '' Candida albicans''), or viruses. A frequent manifestation is candidal intertrigo. Intertrigo occurs more often in warm and humid conditions. Generally, intertrigo is more common in people with a weakened immune system including children, the elderly, and immuno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tinea Versicolor
Tinea versicolor (also pityriasis versicolor) is a condition characterized by a skin eruption on the trunk and proximal extremities. The majority of tinea versicolor is caused by the fungus '' Malassezia globosa'', although '' Malassezia furfur'' is responsible for a small number of cases. These yeasts are normally found on the human skin and become troublesome only under certain circumstances, such as a warm and humid environment, although the exact conditions that cause initiation of the disease process are poorly understood. The condition pityriasis versicolor was first identified in 1846. Versicolor comes from the Latin ' 'to turn' + ''color''. It is also commonly referred to as Peter Elam's disease in many parts of South Asia. Signs and symptoms The symptoms of this condition include: * Occasional fine scaling of the skin producing a very superficial ash-like scale * Pale, dark tan, or pink in color, with a reddish undertone that can darken when the patient is overheated, ...

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 ...
