An elderly woman with a rapidly progressing lower leg ulcer presented with features of systemic inflammatory response syndrome (SIRS). The ulcer had occurred after hitting her leg against a piece of luggage. The causative pathogen in our case was by Corynebacterium ulcerans, demonstrated in bacterial cultures and by PCR. Disease progression was stopped only by Linezolid intravenous. after several other antibiotics failed to help.

However, cutaneous infection with diphtheria is increasingly being diagnosed.
