A Case of Granulocytic Sarcoma of the Lung in Acute Myeloid Leukemia

Background: Granulocytic sarcoma in the lung is a rare presentation of acute myeloid leukemia (AML). Here, we describe a rare case of granulocytic sarcoma of the lung in a 56-year-old male patient with AML. Methods: Hematologic investigation, bone marrow aspirate, cytogenetic analysis, chest computed tomography (CT), and pulmonary biopsy were performed. Results: The patient achieved complete remission (CR) after induction therapy, but the patient refused further treatment and was lost to follow-up. Conclusions: Pulmonary biopsy and bone marrow aspirate are important to confirm a correct diagnosis. Pulmonary granulocytic sarcoma as a prognostic factor needs further studies.
