Introduction:

Behcet's syndrome, also known as Behcet's disease is a chronic autoinflammatory process of low frequency and unknown etiology. It’s an all sizes arteries and veins affecting vasculitis that causes an alteration of endothelial function and is expressed clinically by organ damage at various levels. Its pathogenesis involves genetic, microbial and immunological factors. The most common symptoms are oral and genital ulcers, eye inflammation (uveitis, iritis and retinitis), skin lesions and arthritis.

Objective:

to evaluate several inmunological markers in a patient with Behcet syndrome.

Case presentation:

39 years old masculine patientwith clinical diagnosis of Behcet disease with negative acute phase reactants and serological authoinmunity markers and lymphocyte populations within referential range, without evidences of lymphocyte activation. The presence of a double B lymphocyte population and familial background, suggest the presence of a self recognitionB lymphocyte population and the probable presence of genetic factors, respectively. There was a good response to steroids treatment.

Conclusions:

The study supports the idea that at baseline, not humoral autoimmunity markers, changes in the values of lymphocyte subpopulations, and evidence of lymphocyte activation is detected, but can not exclude the presence of a population of B lymphocytes self-recognition.
