The great imitator with no diagnostic test: pyoderma gangrenosum

Abstract

Pyoderma gangrenosum is a rare, neutrophil-mediated, auto-inflammatory dermatosis that wound care specialists must be prepared to recognise. This condition has clinical features analogous to infectious processes. There is no specific diagnostic test and the diagnosis is usually obtained from exclusion. Its early recognition and proper management with prompt initiation of immunosuppressive therapy are essential to improve the quality of life and the prognosis of patients.
