Delayed diagnosis of human immunodeficiency virus infection in a patient with non-specific neurological symptoms and pancytopenia: a case report.

Introduction: Both non-specific presentation and asymptomatic course of human immunodeficiency virus infection lead to undiagnosed long-term persistence of the virus in a patient's organism.

Case Presentation: Here, we present a case of a 31-year-old Caucasian man with non-specific neurological symptoms and pancytopenia, who was referred to an internal medicine ward for further diagnosis. Upon admission to our hospital, he denied any past risky behaviors and refused to have his blood collected for human immunodeficiency virus testing.
