Pyoderma Gangrenosum: What Do We Know Now?

Abstract

Purpose of Review

To summarize the recent literature on the pathophysiology, diagnosis, and treatment of pyoderma gangrenosum.

Recent Findings

A complex interplay between both the innate and adaptive immune systems underlies the pathogenesis of pyoderma gangrenosum (PG). Diagnosis remains a challenge, as there is no gold standard test to confirm the presence of the disease. Efforts to establish diagnostic criteria based on clinical findings have recently been proposed. Definitive management strategies are also lacking; however, current trends in treatment have favored the use of immunosuppressive medications, wound care management, and analgesia.

Summary

PG is a complex disease that continues to pose a challenge. Current research on PG is focused on improving our understanding of the pathophysiology so that we might improve our diagnostic consistency and identify treatment approaches optimized for each individual patient's specific pathology.
