RESUMO
BACKGROUND: Alpha-1-antitrypsin is the principal serum protease inhibitor. In addition to the well-recognized association with early-onset emphysema and cirrhosis, alpha-1-antitrypsin deficiency may be associated with panniculitis. The treatment of this type of panniculitis presents a significant challenge. Previous attempts using immunosuppressive, anti-inflammatory, and cytotoxic drugs have shown variable results. AIM: To report a case of alpha-1-antitrypsin deficiency-associated panniculitis treated with plasma exchange therapy. METHODS: A 23-year-old patient developed painful red nodules on her thighs and buttocks with spontaneous ulceration and discharge of oily fluid. A skin biopsy specimen showed septal and lobular panniculitis. The serum alpha-1-antitrypsin level was 22 mg/dL. She was treated with plasma exchange therapy. RESULTS: Treatment of this patient with plasma exchange therapy led to the control of the cutaneous lesions. CONCLUSIONS: Plasma exchange therapy represents an alternative treatment which restores serum and tissue alpha-1-antitrypsin levels. This method is proposed because of its clinical benefits and greater availability.
