CyclinD1阳性的B细胞可偶尔出现于反应性淋巴滤泡的套区,此时称为“原位套细胞淋巴瘤”。目前该病变的临床意义还不清楚。本文对23例初诊为“原位套细胞淋巴瘤”的病例进行临床和病理学特征分析,其中也包括SOX11的表达情况。结果发现17/23例符合原位套细胞淋巴瘤的诊断标准,大部分病例是在反应性淋巴结中偶然被发现。17例中
CyclinD1-positive B cells occasionally appear in the reactive lymphoid follicular zone, which is called the “mantle cell lymphoma in situ”. The clinical significance of the lesion is unclear. In this paper, 23 cases of newly diagnosed cases of “mantle cell lymphoma in situ” were analyzed for clinical and pathological features, including the expression of SOX11. The results showed that 17/23 cases meet the diagnostic criteria of in situ mantle cell lymphoma, most cases were found in reactive lymph nodes accidentally. 17 cases
