Gossypiboma Mimicking a Mesenchymal Tumor: A Report of a Rare Case

BACKGROUND Gossypiboma is the term for a surgical complication resulting from foreign materials such as a surgical sponge or gauze that was accidentally left inside a patient's body. CASE REPORT Here, we report the case of a 62-year-old woman with gossypiboma. She underwent surgery due to an abdominal mass that was preoperatively considered a tumor. Intra-postoperatively, it was diagnosed as gossypiboma. CONCLUSIONS For the prevention of gossypiboma during the pre-operative and post-operative periods, counting sponges and surgical equipment must be done very carefully. If there is any doubt postoperatively, direct abdominal imaging may be helpful.
