RESUMEN

BACKGROUND: Foreign body material (gauze sponges) presented as cystic abdominal masses and were confused with malignant tumors. CASES: Two females and one male presented with abdominal masses. They had undergone laparotomy 5-12 years earlier. Clinically the masses were diagnosed as benign or malignant cystic lesions. Fine needle aspiration revealed necrotic material, hemosiderin-laden macrophages, foreign body giant cells, cholesterol crystals and many fragments of birefringent material. The possibility of malignancy was ruled out. Cut sections of the excised cystic lesions revealed gauze sponges surrounded by a thick, fibrotic wall. CONCLUSION: This report underscores the usefulness of fine needle aspiration in ruling out malignancy.
