HighlightsAn abscess with a thick and vascularized wall suggests an intratumoral abscess.GISTs developing into intratumoral abscesses are extremely rare.These GISTs often accompany tumor perforation and peritonitis.Careful handling is eligible in surgery for these GISTs.Administration of Imatinib mesylate should be considered for these GISTs.

HighlightsSmall bowel perforation by an ingested foreign body (FB) is a rare abdominal emergency.Computed tomography scan is most effective but imperfect for diagnosis.Inquiring about FB ingestion and a high index of suspicion are very important.Laparoscopic surgery is effective even in this rare abdominal emergency.Extracorporeal handling of the affected small bowel is useful in this condition.
