RT Journal Article SR Electronic T1 Refractory pemphigus foliaceous treated with rituximab JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e229026 DO 10.1136/bcr-2018-229026 VO 12 IS 5 A1 Fatima Awdeh A1 Eimear Gilhooley A1 Ciara O Grady A1 Maureen Connolly YR 2019 UL http://casereports.bmj.com/content/12/5/e229026.abstract AB Autoimmune blistering diseases are rare but potentially life-threatening conditions. Pemphigus foliaceus is one of these conditions, characterised by superficial erosions of the skin without mucosal involvement. We report the case of a 57-year-old woman who presented with a 4-week history of rash affecting her scalp with associated hair loss. Clinical and histopathological findings were in keeping with pemphigus foliaceus. She was successfully treated with rituximab, a chimeric monoclonal antibody against CD20, leading to a transient depletion of B cells. After 5 months of follow-up, her rash had cleared, and her hair had completely regrown.
