ABSTRACT
To investigate the clinical manifestations and laboratory characteristics of 6 cases of pemphigoid nodularis (PN). The clinical and laboratory data of 6 patients with PN admitted to the Department of Dermatology,Peking Union Medical College Hospital from January 2016 to August 2019 were retrospectively analyzed. PN mainly occurred in middle-aged and elderly people,with an average age of (58±16) years. Eosinophils were elevated in 4 patients. Immunoglobulin E (IgE) level was (530±672) kU/L in five patients. Direct immunofluorescence showed IgG and/or C3 deposition on basal membrane zone. Indirect immunofluorescence showed positive IgG anti-basement membrane zone,with a titer of 140-1320. Enzyme-linked immunosorbent assay showed the anti-BP180 antibodies were positive [24-85 U/ml,average(43±26) U/ml] in 5 patients. None of the patients had neurological disorders. One patient was lost to follow-up. The disease recurred in 3 of 5 patients during the follow-up,and two patients still received maintenance corticosteroids. PN mainly occurs in middle-aged and elderly individuals. It is featured by elevated eosinophils and total IgE and relatively low anti-BP180 antibody titers. Recurrence is common but PN is less likely to be associated with neurological diseases.
