skäringssyndrom

Skäringssyndrom, also known as the Pustula Migrans or Acquired Pustulosis, is a rare dermatological condition characterized by the sudden onset of small, transient pustules on the skin, typically on the face and neck. These pustules are usually non-follicular and resolve spontaneously within a few days, leaving no lasting marks. The exact cause of Skäringssyndrom remains unknown, though it is thought to be an immune-mediated response.

The condition most commonly affects children and young adults, with a slight predilection for females. Clinically, it presents as crops of tiny, yellowish or white pustules, often accompanied by a mild burning or itching sensation. The lesions are usually discrete and do not coalesce. Systemic symptoms are generally absent, and laboratory investigations are typically unremarkable.

Diagnosis is primarily clinical, based on the characteristic appearance and transient nature of the pustules. A biopsy may be performed in atypical cases to rule out other pustular dermatoses. Treatment is often not required due to the self-limiting nature of the condition. However, topical corticosteroids or antibiotics may be prescribed to alleviate symptoms or if a secondary infection is suspected. Recurrences are possible, but the prognosis is generally good.
