Free tissue transfer for pyoderma gangrenosum: A case report

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis characterised by painful progressive skin ulceration. Medical management with corticosteroids and other immunomodulatory agents remains the mainstay of treatment. Surgical intervention has traditionally been avoided because of the risk of pathergy, whereby minor trauma progresses to ulceration. However, extensive or limb-threatening defects may necessitate reconstruction. We present a case of PG affecting the dorsum of the foot requiring free tissue transfer.
