Atypical presentation of Lemierre syndrome in a young healthy man with acute jaundice.

This report presents a case of Lemierre syndrome caused by Fusobacterium necrophorum in a healthy young adult who presented atypically with shortness of breath and jaundice but no clinical or diagnostic evidence of thrombophlebitis. Due to this unusual presentation with jaundice, diagnosis was challenging and delayed. However, the patient was successfully initiated on a prolonged course of intravenous antibiotics; he required a period in the intensive care unit and was discharged without significant complications. This report aims to raise awareness of the diagnosis and treatment of this rare condition and to highlight both common and unusual presentations of the syndrome.

Mixed infection of Actinomyces israelii and Fusobacterium nucleatum presenting as a neck mass.

This report presents the case of a mixed infection of Actinomyces israelii and Fusobacterium nucleatum, presenting as an extensive neck mass progressing through tissue planes and causing bony destruction. Despite multiple abscess aspirates, imaging and serological investigations, the causative organisms proved elusive over the course of the patient's long admission, only to be identified postdischarge. The patient was successfully initiated on a prolonged course of intravenous antibiotics and did not suffer from any complications. This report aims to raise awareness of the presentation, pathogenicity and treatment of Actinomyces and Fusobacteria infections, given a notable difficulty in diagnosis.
