- Centrifugal annular erythema<\/li>\n
- Figurative erythema<\/li>\n
- Perstane erythema<\/li>\n
- Erythema gyratum perstans<\/li>\n
- Erythema figuratum perstans.<\/li>\n<\/ul>\n

<\/span>What are the signs and symptoms of erythema annulare?<\/span><\/h2>\nErythema annulare can occur at any time in life, from infancy to old age. the eruption<\/span> It usually starts as a small, raised, pinkish-red spot that slowly enlarges and forms a ring as the central area flattens and clears. There may be an inner edge of scale<\/span>. The rings enlarge at a rate of approximately 2\u20135 mm \/ day until they reach a diameter of approximately 6\u20138 cm. Sometimes the lesions do not form complete rings, but instead grow in irregular shapes. One or more injuries may be present.<\/p>\nAnull erythema<\/span> It most often appears on the thighs and legs, but can occur on the face, trunk, and arms. The lesions rarely cause symptoms, but may be mildly itchy or itchy in some patients.<\/p>\n\n

<\/span>What Causes Erythema Annulare?<\/span><\/h2>\nOften no specific cause is found for erythema annulare. However, erythema annulare has sometimes been associated with underlying diseases and conditions. These include:<\/p>\n
\n- \nBacterial<\/span>, fungal and viral infections like tuberculosis, secondary syphilis, sinusitis, yeast infection or ringworm\n<\/li>\n
- Medications including chloroquine and hydroxychloroquine, estrogen<\/span>, penicillin and amitriptyline\n<\/li>\n
- Food, most often blue cheese or tomatoes<\/li>\n
- \nRecurrent<\/span> or chronic appendicitis<\/li>\n
- \nCholestatic<\/span> liver disease (blocked biliary system)<\/li>\n
- Graves disease (overactive thyroid gland).<\/li>\n<\/ul>\n
In these situations, the anull erythema<\/span> resolves once the underlying cause or causal drug<\/span> It's stopped.<\/p>\n<\/span>How is the diagnosis of erythema annulare made?<\/span><\/h2>\nThe diagnosis of erythema annulare is made clinically and can be confirmed by histopathology<\/span>, which shows a perivascular<\/span> lymphocytic<\/span> infiltration<\/span>.<\/p>\nMore research can be done to exclude other causes of ring rashes and look for an underlying cause, if any.<\/p>\n
Differential diagnosis<\/span> of annular erythema includes:<\/p>\n\n- Erythem gyratum perstans, a paraneoplastic<\/span> rash associated with underlying malignancy<\/span> in which there are concentric and rotating rings<\/li>\n
- Erythema migrans (Lyme disease)<\/li>\n
- \n
Target lesions in erythema multiforme\n<\/li>\n
- Cancel plates<\/span> with central bullae in fixed drug eruption and bullous<\/span> pemphigoid <\/li>\n
- \nSerpiginous<\/span> plates in cutaneous<\/span> larva migrans\n<\/li>\n
- Cancel dermal<\/span> plates in granuloma<\/span> annular and in a lichen planus shape\n<\/li>\n
- Cancel scaly<\/span> plates in discoid<\/span> eczema<\/span>, chronic license plate<\/span> psoriasis, seborrheic<\/span> dermatitis<\/span>, pityriasis<\/span> rosea, discoid lupus, porokeratosis, and ringworm (dermatophyte infection<\/span>)<\/li>\n
- Smooth annular, Urticated<\/span> injuries in urticaria<\/span>Sweet syndrome<\/span>, polymorphous<\/span> light rash, subacute cutaneous lupus erythematosus and systemic<\/span> lupus erythematosus.<\/span><\/li>\n<\/ul>\n
<\/span>What is the treatment for erythema annulare?<\/span><\/h2>\nErythema annulare usually goes away on its own. The eruptions can last a few weeks or many years (the average duration is 11 months). Most cases of erythema annulare do not require treatment (and there is no known curative therapy). But nevertheless, current<\/span> Corticosteroids can be helpful in reducing redness, swelling, and itching.<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"Que es anular eritema?
