Behcet’s disease: a clinical case of how one uncommon disease was misdiagnosed as another uncommon disease

Bechet’s disease is a rare, multifactorial, systemic inflammatory disease of unknown etiology. Oral and genital ulcers, uveitis, and cutaneous lesions (pseudofolliculitis and erythema nodosum) are its most common manifestations. Less frequent manifestations include lesions of the cardiovascular, joint, gastrointestinal, and nervous systems. There are no specific diagnostic tests for Bechet’s, and the diagnosis is eatablished based on revealed clinical criteria. Due to the variability in clinical presentation, the predominance of non-rheumatic symptoms, and the lack of awareness among physicians, there is often a delay in diagnosis. This can lead to misdiagnosis and unnecessary treatment for patients. This article presents a clinical case of Bechet’s disease, which was initially diagnosed as primary immunodeficiency.
