ABSTRACT Late cutaneous fistula secondary to dropped gallstones is an uncommon complication of laparoscopic cholecystectomy. We present a case with clinical manifestation several years after surgery, characterized by chronic cutaneous drainage of the abdominal wall. Multimodal imaging demonstrated a focus consistent with a retained gallstone within an inflammatory tract, without evidence of communication with the biliary tree. The pathophysiology is related to a chronic foreign body inflammatory reaction. Recognition of this entity and its correlation with surgical history are essential for timely diagnosis and to avoid unnecessary interventions, allowing appropriate clinical and surgical management.
