Erythema multiforme is a skin condition that is identified by distinctive red welts, often called "target lesions," due to their appearance. The spelling of Erythema multiforme is pronounced as ɛrɪˈθiːmə mʌltɪˈfɔːmi, and it is derived from Greek words. Erythema means redness, and multiforme means "many forms." The word "erythema" has a silent "h", and "multiforme" has a hard "c" sound represented by "ch." Understanding the correct spelling of Erythema multiforme is vital, as miscommunications with physicians and medical personnel can have dangerous consequences.
Erythema multiforme is a relatively uncommon skin disorder characterized by the development of distinct skin lesions that usually appear as red, raised patches or circular sores with a target-like appearance. The word "erythema" refers to the redness of the skin, while "multiforme" describes the diverse range of shapes and patterns the lesions can take.
This condition can occur in individuals of any age group, but it typically affects young adults and children. It is believed to be an immune-mediated reaction, often triggered by an infection or exposure to certain medications or substances. Viral or bacterial infections, such as herpes or Mycoplasma pneumoniae, are common causes, as are medications including antibiotics and anticonvulsants.
The key feature of erythema multiforme is its characteristic skin lesions, known as target lesions due to their central dark red area surrounded by a paler ring, which is further surrounded by a red outer ring. These lesions usually appear on the extremities, such as the hands and feet, but can affect other areas of the body as well.
In addition to skin involvement, erythema multiforme may also cause a variety of accompanying symptoms, such as fever, fatigue, joint stiffness, and mucous membrane involvement including the mouth and eyes.
While most cases of erythema multiforme resolve spontaneously within a few weeks to months, treatment may be required to alleviate symptoms. This typically involves managing any underlying infections or discontinuing the causative medication. In severe or recurrent cases, oral corticosteroids or other immunosuppressive medications may be prescribed to reduce inflammation and control the immune response.
A symmetrical eruption of papules or vesicles, usually confined to the back and the dorsal surfaces of the forearms and legs; the lesions are closely aggregated but vary much in size and arrangement, causing appearances to which various descriptive names are given.

The word "erythema multiforme" has its origins in Latin and Greek.
- "Erythema" derives from the Greek word "eruthḗma" (ἐρύθημα), which means "redness" or "flushing". It stems from the verb "eruthaínein" (ἐρυθαίνειν), meaning "to redden".
- "Multiforme" is a Latin word that combines "multi-" meaning "many" or "multiple", and "forma" meaning "form" or "shape".
Therefore, "erythema multiforme" can be translated as "redness with multiple forms" or "redness of various shapes". This term accurately describes the skin condition characterized by distinct erythematous (red) lesions that take on a variety of shapes, including target-like lesions.
