Congenital Infantile Fibrosarcoma of The Duodenum, A Case Report

Background: Congenital infantile fibrosarcoma is a rare soft-tissue tumor in the pediatric age group and seldom involves the gastrointestinal tract. Methods: This study is a case report study done in the Raparin Pediatric Hospital in Erbil on 9 days old boy with signs of intestinal obstruction. After explorative laparotomy a solid mass involving duodenojejunal junction was found, resection of the mass was done with end-to-end anastomosis and approval was taken from patient’s parents. Results: Histopathologic examination showed extensive replacement and effacement of the small bowel architecture by a cellular neoplasm. The tumor was extended through muscularis propria to the serosa with histological features consistent with congenital infantile fibrosarcoma, the diagnosis was confirmed by immunohistochemistry and genetic analysis which demonstrated the t(12;15) translocation. The baby was discharged on the 5th hospital day and followed up for 2 years without recurrence. Conclusion: Here we reported a rare case of congenital infantile fibrosarcoma arising from the small bowel in a new born baby, operated on, totally resected and histopathology proved the diagnosis and the patient was disease free after 2 years follow up.
