Urticarial Erythema Multiforme is a rare skin condition that is characterized by the presence of urticarial lesions and is often mistaken for Erythema Multiforme. It is a distinct clinical entity that is different from Erythema Multiforme, Urticaria, and Urticarial Vasculitis.

Clinical Features

Patients with Urticarial Erythema Multiforme typically present with sudden onset of urticarial lesions that are round, red, and often have a central clearing. These lesions may be accompanied by fever, malaise, and arthralgia. The lesions typically last for less than 24 hours and do not leave any residual pigmentation or bruising.

Diagnosis

The diagnosis of Urticarial Erythema Multiforme is primarily clinical, based on the characteristic appearance of the skin lesions. However, skin biopsy may be performed to rule out other conditions such as Erythema Multiforme and Urticarial Vasculitis.

Treatment

Treatment of Urticarial Erythema Multiforme is primarily symptomatic, with the use of antihistamines to control itching. In severe cases, systemic corticosteroids may be used.

Prognosis

The prognosis of Urticarial Erythema Multiforme is generally good, with most patients experiencing complete resolution of symptoms within a few weeks. However, recurrence is common.
