3例骨内原发造血细胞假瘤的诊断及9年随访

本研究收集、分析3例骨内造血细胞假瘤的临床病理资料，初始临床和病理学诊断，都被误诊为恶性肿瘤/转移灶，其中2例 分别随访了132月和100月，均证明为良性肿瘤（1例失访）。造血细胞假瘤由类似正常造血组织组成的骨内罕见的良性病变，易 被误诊为恶性造血细胞肿瘤，熟知其临床病理特征与转归过程，能够建立正确的个体化诊治方案。

Primary intraosseous hematopoietic pseudotumor: clinicopathological analysis and 9- year follow-up of 3 cases

We analyzed the clinicopathological data of 3 cases of primary intraosseous hematopoietic pseudotumor (IHPT), which had been previously misdiagnosed as malignancies or metastases both clinically and pathologically. Two of the patients received close follow-up for 132 and 100 months, and one patient was lost to follow-up, and the tumors were confirmed to be benign in all the 3 cases. IHPT is a rare benign intraosseous solid lesion consisting of tissues resembling normal hematopoietic tissue, and can be easily misdiagnosed as malignancy. Understanding the clinicopathological features and the outcomes of the disease can facilitate the clinical decisions on individualized diagnosis and therapeutic regimens.
