The rash usually starts as round, slightly raised spots. Some spots develop rings around them and can turn into blisters. Depending on your skin tone, the rash may be red, pink or purple, or it may be darker than surrounding skin.
Erythema multiforme is an allergic reaction. It causes a rash of spots with dark centers and pale red rings that look like a target or "bulls-eye." Some spots can have a small blister or scab in the middle.
Erythema is a skin condition caused by increased blood flow that causes redness, swelling, and irritation. It can take various forms, from mild sunburn to painful lumps or rashes, and is often triggered by infections, medications or allergic reactions. Terry Turner.

Urticaria symptoms resemble erythema multiforme, and these two conditions should be distinguished based on the presentation of the lesions. Erythema multiforme typically has fixed lesions for a minimum of seven days,6 and individual urticarial lesions often resolve within one day.
Erythema means red, but its use is no longer confined to that meaning. One sign of inflammation is redness (Greek: 'erythros'), recognized in Celsus's classical signs of inflammation: calor, dolor, tumor et rubror.
With erythema multiforme major, at least two mucous membranes will have lesions. The rash is still shaped like a bull's-eye in the major type, but it may be slightly larger, and the circles may run into each other. The lesions are more likely to blister and burst, and these areas of skin may be sore and oozing.
The most common early sign of Lyme disease is an expanding skin rash called "erythema migrans." It begins as a reddened area near the tick bite. As the rash increases in size, it often clears in the middle and develops a red ring around the outside, so that it has a “bull's eye” appearance.

Erythema multiforme may be associated with herpes simplex infection, mycoplasma pneumonia, or other medical conditions such as streptococcal infection, tuberculosis (TB), or may result from exposure to chemicals or medications. This individual has erythema multiforme minor, with target lesions on his hands.
Erythema nodosum may be a cutaneous marker of malignancy, most often lymphoma or leukemia. Rarely, other malignancies may be associated with erythema nodosum, including carcinoid and colorectal and pancreatic cancers. Erythema nodosum also can indicate disease progression.
Petechiae from leukemia often resemble a common skin rash, such as atopic dermatitis. However, leukemia rashes have a distinguishing characteristic: When pressure is applied, the spots will retain their red, purple or brown color. Conversely, when pressure is applied to any other type of rash, the skin will turn white.

The allergy can be triggered by taking vitamin B12 supplements because B12 contains cobalt atoms. Cobalt allergies most often develop in people exposed to it in eye makeup, tattoos, or industrial products, causing an itchy, red, scaly rash.
Erythema nodosum can be caused by lots of things, but often the cause is unknown. Common causes include: inflammatory bowel conditions like Crohn's disease and ulcerative colitis. bacterial infections, such a throat infection, chest infection or lung infection (tuberculosis)
Erythema multiforme is an immune-mediated hypersensitivity reaction affecting both the skin and mucous membranes, characterized by the appearance of macular, papular, or bullous lesions that often form distinct "target lesions," primarily found on the extremities.
Major: Erythema multiforme major is the most severe form of the condition. It can be life-threatening because it causes large areas of your skin to blister and peel. This type affects the mucus membranes in your mouth (oral), eyes and genitals. People usually have systemic symptoms such as fevers or joint pain.
Two conditions that cause a similar skin lesion following a tick bite, but are of unknown cause, are Southern tick-associated rash illness in the United States and tick-associated rash illness in Japan.
Necrolytic migratory erythema (NME) is a characteristic skin rash most often associated with glucagonoma, an alpha-cell tumor of the pancreatic islets. It is usually seen as a part of the glucagonoma syndrome, a paraneoplastic syndrome that includes the triad of diabetes mellitus, NME, and weight loss.
If a person does not receive treatment, the bacterium that causes Lyme disease spreads in the body. This is stage 2 of the disease. When the disease is in the second stage, a person may develop a lump or several small oval-shaped rashes on the face, legs, and arms. These may have a dusky center.
