Gossypiboma is a non-absorbable material that is forgotten during surgery. These are medicolegal pathology that leads to diagnostic confusion from abscess to tumor. We present the case of gossypiboma detected in laparotomy in a 57-year-old male patient who had a history of operation due to a hydatid cyst 22 years ago and was referred to our center due to hydatid recurrence. The case should suggest a history of surgical gossypiboma, especially in asymptomatic patients. In this preventable pathology, the strategy during surgery and the careful and proper attitude of the surgical team are the main determinants.
