erythema chronicum migrans

erythema

[er″ĭ-the´mah] redness of the skin caused by congestion of the capillaries in the lower layers of the skin. It occurs with any skin injury, infection, or inflammation.erythema chro´nicum mi´grans a ring-shaped erythema due to the bite of a tick of the genus Ixodes; it begins as an erythematous plaque several weeks after the bite and spreads peripherally with central clearing. Often there are also systemic symptoms, including chills, fever, headache, vomiting, backache, and stiff neck. See also lyme disease.gyrate erythema (erythema gyra´tum) erythema multiforme characterized by the development of lesions that tend to migrate and spread peripherally with central clearing.erythema ab ig´ne permanent erythema produced by prolonged exposure to excessive nonburning heat. It is seen most often on the legs of women, but under appropriate environmental circumstances, it can occur anywhere on the body in either sex.erythema indura´tum a chronic necrotizing vasculitis, usually occurring on the calves of young women; see also bazin's disease.erythema infectio´sum a mild, self-limiting disease of childhood characterized by a lacelike skin rash symmetrically distributed on the hands, arms, and legs, with few or no other symptoms; occasionally there is a low grade fever, and the condition often clears up without specific treatment. The incubation period is six days to two weeks. This disease is contagious and originally was believed to be a form of rubella; because the rash can resemble that of scarlet fever and German measles, it is important to differentiate this mild condition from those more serious ones. Called also fifth disease.erythema margina´tum a type of erythema multiforme in which the reddened areas are disk-shaped, with elevated edges.erythema margina´tum rheuma´ticum a superficial, often asymptomatic, form of gyrate erythema associated with some cases of rheumatic fever, which is characterized by the presence on the trunk and extensor surfaces of the extremities of a transient eruption of flat to slightly indurated, nonscaling, and usually multiple lesions.erythema mi´grans geographic tongue.erythema multifor´me a symptom complex representing a reaction of the skin and mucous membranes secondary to various known, suspected, and unknown factors, including infections, ingestants, physical agents, malignancy, and pregnancy. The conditions in the complex are characterized by the sudden onset of a reddened macular, bullous, papular, or vesicular eruption, the characteristic lesion being the iris, bull's eye, or target lesion, which consists of a central papule with two or more concentric rings. The complex includes a mild self-limited mucocutaneous form (erythema multiforme minor) and a severe, sometimes fatal, multisystem form (stevens-johnson syndrome).erythema nodo´sum a type of panniculitis occurring usually as a hypersensitivity reaction to multiple provoking agents, including various infections, drugs, sarcoidosis, and certain enteropathies. It may also be of idiopathic origin. It most often affects young women and is characterized by the development of crops of transient, inflammatory, nonulcerating nodules that are usually tender, multiple, and bilateral, and most commonly located on the shins; the lesions involute slowly, leaving bruiselike patches without scarring. The acute disease is often associated with fever, malaise, and arthralgias. A chronic variant sometimes occurs without any serious associated systemic disease.toxic erythema (erythema tox´icum) a generalized erythematous or erythematomacular eruption due to administration of a drug or to bacterial or other toxins or associated with various systemic diseases.erythema tox´icum neonato´rum a benign, idiopathic, very common, generalized, transient eruption occurring in infants during the first week of life, usually consisting of small papules or pustules that become sterile, yellow-white, firm vesicles surrounded by an erythematous halo and some edema.

er·y·the·ma chro·ni·cum mi·grans (ECM),

a raised erythematous ring with advancing indurated borders and central clearing, radiating from the site of a tick bite and persisting for 2-16 weeks; the characteristic skin lesion of Lyme disease, due to the spirochete Borrelia burgdorferi, which may be identified by PCR in biopsies.

er·y·the·ma chro·ni·cum mi·grans

(er'i-thē'mă kron'i-kŭm mī'granz) A raised erythematous ring with advancing indurated borders and central clearing, radiating from the site of a tick bite such as that by Ixodes scapularis; the characteristic skin lesion of Lyme disease, due to the spirochete Borrelia burgdorferi.

erythema

(er?i-the'ma ) [Gr. erythema, redness] Reddening of the skin. Erythema is a common but nonspecific sign of skin irritation, injury, or inflammation. It is caused by dilation of superficial blood vessels in the skin. erythematicerythematous (er?i-the-mat'ik) (er?i-them'at-us), adjective

erythema ab igne

Localized erythema due to exposure to heat. Synonym: toasted skin syndrome.

ERYTHEMA ANNULARE

erythema annulare

A red, ring-shaped rash. See: illustration

erythema cenicienta

Erythema dyschromicum perstans.

erythema chronicum migrans

Abbreviation: ECM
Erythema migrans.

erythema dyschromicum perstans

Awaiting Don's def. Synonym: ashy dermatosis; erythema cenicienta

erythema elevatum diutinum

A form of vasculitis that affects the skin on the extensor surfaces of the forearms or legs. Iit is often seen in those infected with HIV.

erythema induratum

Chronic vasculitis of the skin occurring in young women. Hard cutaneous nodules break down to form necrotic ulcers and leave atrophic scars. Synonym: Bazin disease

erythema infectiosum

A mild, moderately contagious disease seen most commonly in school-age children. Synonym: fifth disease

Etiology

The causative agent is human parvovirus B-19. Transmission is thought to be via respiratory secretions from infected patients; however, maternal-fetal transmission can occur and hemolytic disease of the newborn may result.

Symptoms

Patients experience a mild, brief illness; complaints include fever, malaise, headache, and pruritus. The characteristic erythema appears about 10 days later. Facial redness is similar to that which occurs when a child is slapped; however, circumoral redness is absent. Several days following initial erythema, a less distinct rash may appear on the extremities and trunk. The rash usually resolves within 1 week but may occur for several weeks when the patient is exposed to heat, cold, exercise, or stress. Adults may also experience arthralgia and arthritis although these symptoms are less common in children. In addition, mild transient anemia, thrombocytopenia, and leukopenia may develop.

Treatment

Most patients require no specific therapy. Patients with chronic hemolytic anemia may experience transient aplastic crisis (TAC). These patients should be warned of the danger of exposure to parvovirus B-19 infection, informed of the early signs and symptoms, and instructed to seek medical consultation promptly if exposure is suspected. Patients with TAC may develop a life-threatening anemia that requires immediate blood transfusion or partial exchange transfusion.

erythema intertrigo

Chafing.

linear gingival erythema

A band of inflammation of the periodontium, appearing as a reddish gingival band about 2 to 3 mm in width. It is often associated with HIV/AIDS. Synonym: red band gingivitis

erythema marginatum

A form of erythema multiforme in which the center of the area fades, leaving elevated edges.

erythema migrans

Abbreviation: EM
The hallmark of acute infection with Lyme disease. EM is an expanding red rash with a sharply defined border and (typically) central clearing. The rash usually appears within 3–32 days after a tick bite. The center of the rash is the site of inoculation. The causative agent is Borrelia burgdorferi, a spirochete that may later invade the joints, the central nervous system, or the conducting system of the heart. Synonym: erythema chronicum migrans See: Lyme disease for illus

ERYTHEMA MULTIFORME

erythema multiforme

Abbreviation: EM
A rash usually caused by an immune response to drugs or to an infection, esp. herpes simplex virus. It may express itself on the skin in multiform ways, including macules, papules, blisters, hives, and, characteristically, iris or target lesions. It may involve the palms and soles, the mucous membranes, the face, and the extremities. The disease is usually self-limited. The most severe (and occasionally fatal) variant of the illness, in which the eyes, mouth, and internal organs are involved, is called Stevens-Johnson syndrome, or toxic epidermal necrolysis. Synonym: Hebra disease (1.) See: illustration

necrolytic migratory erythema

Abbreviation: NME
Red, blistering or crusting patches that appear on the skin of the buttocks, groin, lower extremities, or perineum. The lesions are itchy and painful. NME is often associated with glucagonomas.

erythema nodosum

A tender, red, nodular rash on the shins that typically arises in conjunction with another illness, e.g., such as a streptococcal, fungal, or tubercular infection; inflammatory bowel disease; occult cancer; or sarcoidosis. Biopsies of the rash reveal inflammation of subcutaneous fat (panniculitis). Because the disease is often associated with other serious illnesses, a diagnostic search for an underlying cause usually is undertaken. In some patients, no cause is identified.

Treatment

Therapy is directed at the cause, when it is known. Nonsteroidal anti-inflammatory drugs provide symptomatic relief for many patients.

erythema nodosum leprosum

Abbreviation: ENL
A red, nodular vasculitic rash, which may be a complication of the treatment for leprosy. See: lepra

Treatment

Treatment consists of withdrawing therapy against leprosy (clofazimine, steroids, thalidomide).

punctate erythema

Erythema occurring in minute points, such as scarlet fever rash.

toxic erythema

Redness of the skin or a rash resulting from toxic agents such as drugs.

erythema toxicum neonatorum

A benign, self-limited rash marked by firm, yellow-white papules or pustules from 1 to 2 mm in size present in about 50% of full-term infants. The cause is unknown, and the lesions disappear without need for treatment.

erythema venenatum

Erythema caused by contact with a toxic substance.

Afzelius,

Arvid, Swedish physician, 1857-1923. Afzelius erythema - single lesions of erythema annulare centrifugum which erupt and spread. Synonym(s): erythema chronicum migrans; Lipschütz erythema
