粒细胞肉瘤是一种罕见的发生于髓外由未成熟髓系细胞构成的实体瘤,又称绿色瘤。因其组织形态难以与其他肿瘤鉴别,故经常导致误诊。近年来由于免疫组织化学染色技术在临床上的广泛应用,粒细胞肉瘤的诊断准确性明显提高。研究表明,综合应用髓过氧化物酶、CD56、CD117、CD13、CD14等免疫标记,基本上能确诊粒细胞肉瘤。 Granulocytic sarcoma is a rare solid tumor that is composed of immature myeloid cells, also called green tumor. Because of its difficult to identify with other tumor tissue morphology, it often leads to misdiagnosis. In recent years due to immunohistochemical staining in clinical widely used, granulocytic sarcoma diagnostic accuracy was significantly improved. Studies have shown that comprehensive application of myeloperoxidase, CD56, CD117, CD13, CD14 and other immune markers, basically can diagnose granulocytic sarcoma.
