Unexplained bruising: a developing story.

We present the case of a 10-month-old male infant who presented to accident and emergency with unexplained bruising of the ear. Initial blood tests showed no clotting or platelet abnormalities and non-accidental injury investigation commenced. He was subsequently reviewed by the dermatology team who suggested the diagnosis of acute haemorrhagic oedema of infancy presumably triggered by a viral or bacterial infection, and the clinical findings fit this diagnosis.

An unusual case of seronegative, 16S PCR positive infection.

Introduction: is a zoonotic infection commonly diagnosed by isolation of the organism from blood culture or positive serological testing. It is an uncommon cause of a pyrexia of unknown origin in the United Kingdom.

Case Presentation: We describe the case of a 14-year-old girl with no history of travel who presented with pyrexia, weight loss, arthralgia, multiple splenic abscesses and a subsequent pleural effusion, the latter of which isolated a species on 16S rRNA PCR.
