Erythema multiforme minor is a skin condition characterized by the sudden onset of red, target-like spots on the skin. It is considered the milder form of Erythema multiforme, a condition that can also affect the mucous membranes.

Causes

Erythema multiforme minor is often triggered by an infection, most commonly the Herpes simplex virus. Other potential triggers include Mycoplasma pneumoniae and certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), anticonvulsants, and antibiotics.

Symptoms

The primary symptom of erythema multiforme minor is the appearance of red, target-like spots on the skin. These spots typically appear suddenly and may be accompanied by mild itching or burning. Unlike erythema multiforme major, the minor form does not affect the mucous membranes.

Diagnosis

The diagnosis of erythema multiforme minor is typically based on the characteristic appearance of the skin lesions. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other conditions.

Treatment

Treatment for erythema multiforme minor primarily involves managing the symptoms and addressing the underlying cause, if known. This may include antiviral medication for herpes simplex virus infections, or discontinuing the use of a triggering medication. Over-the-counter creams and ointments may also be used to help relieve itching and burning.

Prognosis

The prognosis for erythema multiforme minor is generally good. The condition usually resolves on its own within a few weeks, although it can recur in some individuals.
