Pelvic abscess caused by Arcanobacterium haemolyticum mimicking a soft tissue tumour

Abstract

Arcanobacterium haemolyticum has usually been isolated in cases of pharyngitis and wound infections. Rarely it has been reported to cause deep tissue infections. Here, a case of a 71-year-old-male, who developed a pelvic abscess due to A. haemolyticum that initially was thought to be a malignant tumour, is described.
