Erythema Nodosum The tender lumps, or nodules, of erythema nodosum range in size from one to five centimeters. The nodular swelling is caused by a inflammation in the fatty layer of skin.Erythema nodosum can be self-limited and resolve on its own in three to six weeks. Upon resolution, it may leave only a temporary bruised appearance or leave a chronic indentation in the skin where the fatty layer has been injured.rythema nodosum is a type of skin inflammation that is located in a certain portion of the fatty layer of skin.

- xeroderma pigmentosum-caused by mutations in the XPA gene. At least 25 mutations in the XPA gene have been found to cause xeroderma pigmentosum. Mutations in this gene are responsible for a very severe form of the disorder that is more common in the Japanese population than in other populations.t least 25 mutations in the XPA gene have been found to cause xeroderma pigmentosum.

Erythema Annulare Centrifugum The pathogenesis of erythema annulare centrifugum (EAC) is unknown, but it is probably due to a hypersensitivity reaction to a variety of agents, including drugs, arthropod bites, infections (bacterial, mycobacterial, viral, fungal, filarial), ingestion (blue cheese Penicillium), and malignancy.

- In half of all cases of either erythema multiforme or erythema nodosum, the exact cause is not known. In other cases, a variety of causes may result in erythema. Erythema multiforme: 1  Infection, primarily from the herpes simplex virus (HSV).2  Medications, such as penicillin and sulfa drugs; antiseizure medications; nonsteroidal anti-inflammatory drugs (NSAIDs).hotosensitivity is caused by a reaction to sunlight and tends to occur when something, such as an infection or a medication, increases your sensitivity to ultraviolet radiation. Erythema multiforme is characterized by raised spots or other lesions on the skin.

Erythema Nodosum Erythema nodosum is a type of skin inflammation that is located in a part of the fatty layer of skin. Erythema nodosum results in reddish, painful, tender lumps most commonly located in the front of the legs below the knees. The tender lumps, or nodules, of erythema nodosum range in size from a dime to a quarter.They may be inflamed off and on for a period of weeks, then shrink and become flat, leaving a bruised appearance. Erythema nodosum can go away on its own in three to six weeks.rythema nodosum is initially managed by identifying and treating any underlying condition, along with the skin lesions. Treatments for erythema nodosum include anti-inflammatory drugs, and cortisone by mouth or injection. Colchicine is sometime used effectively to reduce inflammation.

- What Is Erythematous Gastritis? Gastritis occurs when the lining of the stomach becomes inflamed or irritated and may also refer to the erosion of the lining. Erythematous occurs when there is redness of the skin because of dilation of blood vessels. In some cases, it is a normal response due to inflammation and can hasten healing.

Bloom Syndrome (Congenital Telangiectatic Erythema) Pathophysiology. Bloom syndrome (congenital telangiectatic erythema) is caused by a mutation in both alleles of the gene designated BLM, traced to band 15q26.1. BLM encodes 1417 amino acids that code for a protein in the nuclear matrix of growing cells, which is a member of the RecQ family of helicases.hotosensitivity in Bloom syndrome patients is a result of increased susceptibility to 313-nm light, approaching the ultraviolet (UV)–A range. The minimal erythema dose threshold for both UV-A and UV-B are reduced.

Discoid Lupus Erythematosus Discoid lupus erythematosus is an autoimmune disorder affecting the skin. The disorder causes a skin rash or lesions that usually appear on the scalp, nose and cheeks.Loss of hair and changes in skin pigment also occur with this disorder.

- Quick Answer. Erythematous mucosa of the stomach is a red, irritated lining within the stomach. This condition is generally seen when a patient has a diagnosis of gastritis, and the inflamed stomach lining is seen during an endoscopic evaluation. Biopsies may or may not be taken during endoscopy to evaluate and diagnosis the cause of the erythema.

- Xeroderma pigmentosum is caused by mutations in genes that are involved in repairing damaged DNA. DNA can be damaged by UV rays from the sun and by toxic chemicals such as those found in cigarette smoke. Normal cells are usually able to fix DNA damage before it causes problems.nherited abnormalities in the NER-related genes prevent cells from carrying out one or more of these steps. The POLH gene also plays a role in protecting cells from UV-induced DNA damage, although it is not involved in NER; mutations in this gene cause the variant type of xeroderma pigmentosum.

- Erythema multiforme. Erythema multiforme (EM) is a  skin condition of unknown cause; it is a type of erythema possibly mediated by deposition of immune complexes (mostly IgM-bound complexes) in the superficial microvasculature of the skin and oral mucous membrane that usually follows an infection or drug exposure.
