Scleromyxedema
Papular mucinosis (also known as scleromyxedema, "generalized lichen myxedematosus" and "sclerodermoid lichen myxedematosus") is a rare skin disease. Localized and disseminated cases are called papular mucinosis or lichen myxedematosus while generalized, confluent papular forms with Sclerosis (medicine), sclerosis are called scleromyxedema. Frequently, all three forms are regarded as papular mucinosis. However, some authors restrict it to only mild cases. Another form, acral persistent papular mucinosis is regarded as a separate entity. Presentation Papular mucinosis is chronic and may be progressive. The dermal layer of the skin breaks out into small and solid bumps, usually conical in shape and measured from 2 to 4 mm or sometimes flat-topped papules. Unlike pustules, these bumps do not contain pus. Instead they contain mucin, a waxy substance of mucus, the body's natural and protective lubricant found in saliva and epithelial cells in lungs and the sensitive part of the n ...

Acral Persistent Papular Mucinosis
Acral persistent papular mucinosis (APPM) is a rare form of lichen myxedematosus. It is characterized by small papules on the backs of the hands, wrists, and extensor aspects of the distal forearms, with no further clinical or laboratory indications. Lesions tend to persist and may grow in number gradually. Because there are no symptoms, treatment is rarely required. Signs and symptoms Acral persistent papular mucinosis is a chronic idiopathic cutaneous mucinosis with the following characteristics: # Papules, Nodule (medicine), nodules, and/or Skin plaque, plaques of Lichenoid eruption, lichenoid origin # Mucin deposition in conjunction with varying degrees of dermal fibrosis and fibroblast proliferation # The absence of thyroid disease. Causes The cause of Acral persistent papular mucinosis is unknown, but genetic and environmental factors appear to play a role, as familial cases have been reported. TNF-α and TGF-β have been proposed to stimulate glycosaminoglycan synthesis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discrete Papular Lichen Myxedematosus
Discrete papular lichen myxedematosus is a skin condition caused by fibroblasts producing abnormally large amounts of mucopolysaccharides characterized by the occurrence of waxy, flesh-colored papules.. Signs and symptoms Discrete papular lichen myxedematosus is typically identified by the presence of violaceous, flesh-colored, or reddish, waxy papules that range in size from 2 to 5 mm and that symmetrically affect the trunk and limbs. Causes This disease's etiology is still unknown. Diagnosis Histologically, a normal epidermis is covered by a diffuse or focal mucinous deposit and edema in the upper and mid dermis. Although there isn't any sclerosis or collagen deposition, fibroblast proliferation varies. Treatment Numerous therapies have been attempted, with varying degrees of success, such as dermabrasion, CO2 laser, intralesional injections of corticosteroids or hyaluronidase, oral retinoids, psoralen ultraviolet A, and pimecrolimus. Given its ability to inhibit bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sclerosis (medicine)
Sclerosis () is the stiffening of a tissue or anatomical feature, usually caused by a replacement of the normal organ-specific tissue with connective tissue. The structure may be said to have undergone sclerotic changes or display sclerotic lesions, which refers to the process of sclerosis. Common medical conditions whose pathology involves sclerosis include: * Amyotrophic lateral sclerosis—also known as Lou Gehrig's disease or motor neurone disease—a progressive, incurable, usually fatal disease of motor neurons. * Atherosclerosis, a deposit of fatty materials, such as cholesterol, in the arteries which causes hardening. * Focal segmental glomerulosclerosis is a disease that attacks the kidney's filtering system ( glomeruli) causing serious scarring and thus a cause of nephrotic syndrome in children and adolescents, as well as an important cause of kidney failure in adults. * Hippocampal sclerosis, a brain damage often seen in individuals with temporal lobe epilepsy ...

Esophagus
The esophagus (American English), oesophagus (British English), or œsophagus (Œ, archaic spelling) (American and British English spelling differences#ae and oe, see spelling difference) all ; : ((o)e)(œ)sophagi or ((o)e)(œ)sophaguses), colloquially known also as the food pipe, food tube, or gullet, is an Organ (anatomy), organ in vertebrates through which food passes, aided by Peristalsis, peristaltic contractions, from the Human pharynx, pharynx to the stomach. The esophagus is a :wiktionary:fibromuscular, fibromuscular tube, about long in adults, that travels behind the trachea and human heart, heart, passes through the Thoracic diaphragm, diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word ''esophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, "I carry") + ἔφαγον ( ...

Prednisone
Prednisone is a glucocorticoid medication mostly used to immunosuppressive drug, suppress the immune system and decrease inflammation in conditions such as asthma, COPD, and rheumatologic diseases. It is also used to treat high blood calcium due to cancer and adrenal insufficiency along with other steroids. It is taken Oral administration, by mouth. Common side effects may include cataracts, Osteoporosis, bone loss, easy bruising, muscle weakness, and oral candidiasis, thrush. Other side effects include weight gain, swelling, high blood sugar, increased risk of infection, and psychosis. It is generally considered safe in pregnancy and low doses appear to be safe while the user is breastfeeding. After prolonged use, prednisone must be stopped gradually. Prednisone is a prodrug and must be converted to prednisolone by the liver before it becomes active. Prednisolone then binds to glucocorticoid receptors, activating them and triggering changes in gene expression. Prednison ...

Cyclophosphamide
Cyclophosphamide (CP), also known as cytophosphane among other names, is a medication used as chemotherapy and to suppress the immune system. As chemotherapy it is used to treat lymphoma, multiple myeloma, leukemia, ovarian cancer, breast cancer, small cell lung cancer, neuroblastoma, and sarcoma. As an immune suppressor it is used in nephrotic syndrome, ANCA-associated vasculitis, and following organ transplant, among other conditions. It is taken by mouth or injection into a vein. Most people develop side effects. Common side effects include low white blood cell counts, loss of appetite, vomiting, hair loss, and bleeding from the bladder. Other severe side effects include an increased future risk of cancer, infertility, allergic reactions, and pulmonary fibrosis. Cyclophosphamide is in the alkylating agent and nitrogen mustard family of medications. It is believed to work by interfering with the duplication of DNA and the creation of RNA.

Lesions
A lesion is any damage or abnormal change in the tissue of an organism, usually caused by injury or diseases. The term ''Lesion'' is derived from the Latin meaning "injury". Lesions may occur in both plants and animals. Types There is no designated classification or naming convention for lesions. Because lesions can occur anywhere in the body and their definition is so broad, the varieties of lesions are virtually endless. Generally, lesions may be classified by their patterns, sizes, locations, or causes. They can also be named after the person who discovered them. For example, Ghon lesions, which are found in the lungs of those with tuberculosis, are named after the lesion's discoverer, Anton Ghon. The characteristic skin lesions of a varicella zoster virus infection are called ''chickenpox''. Lesions of the teeth are usually called dental caries, or "cavities". Location Lesions are often classified by their tissue types or locations. For example, "skin lesions" or " b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cutaneous Mucinosis Of Infancy
Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin ''cutis'' 'skin'). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue and guards the underlying muscles, bones, ligaments, and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. Skin (including cutaneous and subcutaneous tissues) plays crucial roles in formation, structure, and function of extraskeletal apparatus such as horns of bovids (e.g., cattle) and rhinos, cervids' antlers, giraffids' ossicones, armadillos' osteoderm, and os penis/os clitoris. All mammals have some hair on their skin, even marine mammals like whales, dolphins, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
