It can mimic soft tissue sarcoma. Clinical and radiological findings may not be enough to solve the puzzle and histology remains the mainstay of diagnosis. Aim: Our aim is to highlight the unusual long interval between initial surgery and presentation of foreign body granuloma. Case Presentation: A 65-year-old man who presented 48 years after initial surgery with progressive painless fascia lata donor site soft tissue swelling. The management and histology findings were highlighted. Conclusion: The occurrence of foreign body granuloma remains an important differential following a history of past surgical procedure regardless of the time interval between the surgical procedure and the clinical presentation.展开更多
