Abstract
Myeloid sarcoma is a rare aggressive tumour that originates from immature extramedullary myeloid cells. It can be seen as a relapse in patients with acute myeloid leukaemia. Sometimes it can be seen in the form of a solid tumour without any evidence of leukaemia. A case of a 44-year-old male patient who was admitted with symptoms and signs of mechanical intestinal bowel obstruction was operated on. The operation findings showed small bowel obstruction due to a mass. The mass was then resected with end-to-end intestinal anastomosis. The resected mass pathology results were consistent with myeloid sarcoma. The post-operative period was uneventful and adjuvant therapy was applied. In this case report we aimed to evaluate the clinical signs and treatment modalities of small intestinal myeloid sarcoma.
