Extramedullary hematopoiesis is a rare condition defined as the appearance of hematopoietic elements outside of the bone marrow, which occurs primarily in patients with chronic myeloproliferative disorders or congenital hemolytic anemias. We report a patient who presented with a left lower lobe lung carcinoma and right paravertebral and left pleural masses, initially thought most consistent radiographically with inoperable metastatic disease, until biopsies of the paravertebral and pleural masses established the presence of extramedullary hematopoiesis. The left lower lobe neoplasm was subsequently resected uneventfully.
髓外造血是一种罕见的病症，定义为骨髓外出现造血成分，主要发生在慢性骨髓增殖性疾病或先天性溶血性贫血患者中。我们报告了一名患者，其表现为左下叶肺癌以及右椎旁和左胸膜肿块，最初影像学上认为最符合无法手术的转移性疾病，直到对椎旁和胸膜肿块进行活检确定存在髓外造血。随后顺利切除了左下叶肿瘤。
