title: Helicobacter cinaedi bacteremia presenting as macules in an afebrile patient with X-linked agammaglobulinemia.
abstract: We describe a 54-year-old man with X-linked agammaglobulinemia (XLA) and Helicobacter cinaedi bacteremia, who presented with tender, hyper-pigmented skin macules without increased local warmth or fever. We propose that this presentation may be a characteristic early sign of bacteremia caused by H. cinaedi and related organisms in otherwise healthy immunocompromised patients. This case demonstrates the importance of a high index of suspicion for H. cinaedi bacteremia in immunocompromised patients with unexplained skin lesions.
