Objective:
Granulocytic sarcoma also called myeloid sarcoma is an extramedullary tumour of immature granulocytic cells. It is a rare entity, and mostly accompanied by acute myeloid leukaemia. It is observed during the course of myeloproliferative disorders especially in chronic myeloid leukaemia and myelodysplastic syndromes.
Conclusions:
Here, we report a case of a 60-year-old male with past history of myelofibrosis admitted to the emergency room due ulceronecrotic lesions, fever and dysphagia. We emphasize the importance of recognizing this entity and its severity.
