Pseudo-Behçet's disease.

The conditions of complex aphthosis, EM, MMP, and the VVG variant of erosive oral LP may be confused by clinicians who refer patients for diagnosis and management of BD (Table 8). The mucocutaneous presentations or the presence of complex aphthosis, the hallmark of BD, can be confusing and lead to the referral of the patient for a diagnosis of BD. The astute clinician evaluating patients for BD considers pseudo-BD in the differential diagnosis of the mucocutaneous manifestations of BD.
