Erythema Marginatum

Erythema Marginatum

Erythema marginatum is a kind of a disease where the skin or the mucous membrane reddens. It is known to affect the inner surfaces of the hands and legs as well as form pink rings on the chest. Therefore, this condition causes the skin margins to be red. Inflammation of blood vessels is associated with the inception of erythema marginatum initiated by the lymphocytes histiocytes. However, it does affect the face, and minimal cases have been reported.

Erythema marginatum stays as long as several days to several months and even years and is majorly ignored by victims since it neither itches nor is it painful. An approximate of 5-10% of patients with dire rheumatic fever suffer this disease. Some of the symptoms of this illness are rash on the skin surface, fever, general body weakness, itching of the skin, pain in the joints and numerous skin lesions which quickly which appear and disappear occasionally and may spread or appear as a nodule or macule resembling hives. Furthermore they have a central sore surrounded by pale red rings, also called “Iris,” or “bulls-eye.” This disease upsets superficial layer. It is, however, unknown what the actual cause of erythema marginatum is.

Some Doctors argues that the Erythema marginatum is not a disease rather, a skin condition indicating an underlying disorder. Erythema marginatum is of two types: erythema marginatum perstans which occur after very short intervals, which is seen on both legs and arms making it appear like a permanent disease. This kind is chronic. The second type is the erythema marginatum rheumatism which doesn’t show any symptoms. This kind affects both the chest as well as limbs, and its occurrence is superficial. The lesion is a little bit raised compared to the center of the ring which has a flattened surface. As the time goes by the size of the rings will increase and eventually assume an irregular shape

Erythema marginatum does not cause any form of distress as it does itch or have a burning sensation. However, care should be taken especially in hot surroundings as the heat intensifies. Such places include hot baths with extreme temperatures which are more than room temperatures. Erythema marginatum is associated with diseases such as carditis, arthritis, fever and Sydenham chorea and few circumstances of allergic drug reaction.

Conditions that can also give rise to the Erythema Marginatum is pregnancy, allergy, hereditary angioedema, etc. The diagnosis of erythema marginatum is done in two ways, firstly by observing the existence of rheumatic fever and on rare cases the specialist focus on skin biopsy where the skin rash act as the diagnostic clue. This is because according to most scientists, they deem this as a symptom and not the actual disease. This has resulted in looking for a treatment which is not directed towards the disease but rather to then underlying condition which is the rash. The erythema marginatum associated with rheumatic fever is treated with an antibiotic not directed for erythema margintum but meant for rheumatic fever.
