Urticarial erythema multiforme
Urticarial Erythema Multiforme
Urticarial Erythema Multiforme (pronounced: ur-ti-kar-ial er-y-the-ma mul-ti-form) is a rare and distinct variant of erythema multiforme that predominantly affects children and young adults. The term is derived from the Latin urtica (nettle), referring to the hives-like presentation, and erythema multiforme, a skin condition characterized by the appearance of multiform (multiple and diverse) lesions.
Symptoms
The condition is characterized by the sudden onset of urticarial (hives-like) lesions that may evolve into typical target lesions or raised, round, red spots. Other symptoms may include fever, malaise, and upper respiratory tract symptoms.
Causes
The exact cause of Urticarial Erythema Multiforme is unknown, but it is often associated with infections, particularly herpes simplex virus and mycoplasma pneumoniae. It can also be triggered by certain medications.
Diagnosis
Diagnosis is typically based on the characteristic clinical presentation. A skin biopsy may be performed to confirm the diagnosis and rule out other conditions such as urticaria, erythema multiforme, and Stevens-Johnson syndrome.
Treatment
Treatment usually involves managing the symptoms with antihistamines and corticosteroids. In severe cases, hospitalization may be required.
Prognosis
The prognosis for Urticarial Erythema Multiforme is generally good, with most patients experiencing a full recovery within a few weeks. However, recurrence is common.
