Myelodysplastic syndrome presenting as a Behçet's-like disease with aortitis.

A 46-year-old Hispanic man presented with fever, genital ulcers, left eye redness and chest pain. Physical examination was notable for a healed oral ulcer and scrotal ulcers, and bilateral superficial thrombophlebitis. He was found to have new-onset pancytopenia. CT of the chest showed pericardial and pleural effusions and rapidly progressing inflammation of the aortic arch and ascending vessels. Although the patient had Behcet's disease (BD)-like symptoms, pancytopenia could not be explained by the diagnosis, prompting a bone marrow biopsy which showed myelodysplastic syndrome. This report highlights the importance of excluding alternate disorders before making a diagnosis of Behcet's disease if atypical, BD-incompatible or incomplete constellations of symptoms and findings are present.
