Abstract
BACKGROUND
The diagnosis of pemphigus vulgaris and pemphigus foliaceus is usually based on clinical, histological, and immunofluorescence (IF) findings. In recent years, the antigenic profile of both diseases has been further defined by immunobiochemical techniques (ELISA, immunoblot, and immunoprecipitation).
METHODS
A retrospective study of 40 pemphigus patients was performed to determine the clinical, histological, and antigenic profile in patients with pemphigus followed at our Department. Charts review, clinical data, histological and IF findings, and antigenic analysis by ELISA were performed in all patients.
RESULTS
In most patients, there was a perfect correlation between the clinical and histological findings and their antigenic profile. In four patients (10%), clinicopathological features and antigenic findings were discordant.
CONCLUSIONS
The antigenic profiles in pemphigus do not always correlate with the clinical diagnosis. Therefore, clinical and histological features should be considered as the mainstay for the diagnosis of pemphigus.
