Calcifying fibrous tumor (CFT) is a rare benign lesion, mostly located in soft tissues, pleura and peritoneum. Differential diagnosis and total excision of the lesions are important. This is a case of a nineteen years old boy admitted to the emergency service with colic abdominal pain, guarding and rebound tenderness. Imaging modalities revealed nothing except minimal fluid at pelvic area. After 12 hours follow up, due to increament of rebound tenderness and guarding, the patient was taken to laparotomy. At exploration, 7x5x4 cm mass between small intestine mesentery and transverse colon mesentery, three 2x1x1 cm mass at antimesenteric part of terminal ileum, multiple white-gray calcified milimetric lesions at omentum and multiple lymphadenopathies (LAP) at ileum mesentery were determined. Omentum, all described lesions and 2 LAPs were excised. Treatment of CFT is total excision of lesions. No death or no metastasis are declared but few local recurrences are reported. Follow up is important.
