Background: Papulopustular lesions are common in Behçet's syndrome (BS). A debate exists as to whether they are different from ordinary acne. This has important clinical and pathophysiologic implications.
Objective: The aim of this study was to evaluate the histopathologic features of papulopustular lesions seen both in BS and acne vulgaris (AV).
Methods: Representative samples were obtained from 17 patients with BS and six patients with AV. The detailed histopathologic features were evaluated by a dermatopathologist blinded to the diagnoses.
Results: Considering the epidermis, follicle epithelium, and dermis separately, no differences could be found between the two groups.
Conclusions: The papulopustular lesions seen in these two disorders cannot be distinguished on the basis of clinical and histopathologic findings.
