BACKGROUND: Myelodysplastic syndromes (MDS) are clonal stem cell disorders of the bone marrow. Most patients with MDS have a high risk of bleeding. Thrombocytopenia and defective platelet aggregation contribute to bleeding. We report a surgical case of a patient with lung cancer concomitant with MDS.
CASE PRESENTATION: A 72-year-old man presented to our hospital because of an abnormal shadow on chest x-ray suggesting a primary lung cancer. A peripheral blood smear examination found giant platelets without thrombocytopenia. He was diagnosed with MDS by bone marrow biopsy, and showed defective platelet aggregation despite a normal bleeding time. The patient underwent left lower lobectomy and transfusion of platelets because of chest wall bleeding.
CONCLUSIONS: We demonstrated that ordering platelet preparations might be desirable for an MDS patient with defective platelet aggregation who will undergo surgery, even for a normal platelet count and bleeding time.
