Extramedullary hematopoeisis (EMH), also known as myeloid metaplasia can be seen in association with various hematological disorders. The common sites of EMH are liver, spleen and lymph nodes; but it can occur in almost any organ and in numerous locations. Involvement of the thyroid gland with EMH has rarely been reported. We present a case of EMH in the thyroid gland in an adult female diagnosed on fine-needle aspiration cytology (FNAC) which further helped in revealing an underlying myeloproliferative neoplasm; chronic myeloid leukemia (CML).
髓外造血（EMH），也称为髓样化生，可见于多种血液系统疾病。EMH的常见部位是肝脏、脾脏和淋巴结；但它几乎可发生于任何器官及众多部位。甲状腺受累于EMH的情况鲜有报道。我们报告一例成年女性甲状腺EMH病例，通过细针穿刺抽吸活检（FNAC）确诊，这进一步有助于揭示潜在的骨髓增殖性肿瘤；慢性粒细胞白血病（CML）。
