Objectives/Interrogation: Pyoderma gangrenosum (PG) is a rare inflammatory skin disorder. It is typically associated with chronic systemic inflammatory or neoplastic diseases, but may also arise secondary to the injury or surgery (pathergy). PG is difficult to be diagnosed. Currently it is a "diagnosis of exclusion". We present a case of postinjury PG of the little finger.

Case Report: 69-year-old female was admitted to our clinic with suspicion of finger cellulitis. She reported to injured her left little finger 5 days before. Since then she is complaining about increasing redness, swelling and functio laesa. Despite operative debridement of the wound, the local findings became worse. The patient was consulted by our dermatologist. The diagnosis of pyoderma gangrenosum can only be made from clinical and histological findings according to the Mayo criteria. Based on this we evaluated the major and criteria. Under the prednisolone administration, there was a significant improvement. After completion of the diagnosis, therapy with ciclosporin and prednisolone was initiated. After a week of systematic therapy, the skin defect on the little finger was covered with split skin from the left elbow. After the week, the patient was discharged home. The control after two months continues to show good results without recurrence signs.
