Fig1 2x ;Fig2 20x 交界;Fig3 20x 肿瘤;Fig4 40x 肿瘤
肿瘤在不同区域显示相通的形态学
请给出你的鉴别诊断,如果这是你的病例,你选择哪些免疫标记。根据HE切片你诊断什么?
我将出去度假几周,回来后将上传免疫图片或结果。
谢谢。

肿瘤位于表皮下,与表皮没有关系,表皮正常。瘤细胞弥漫性分布,细胞异型性明显,核分裂像多见,可见病理性核分裂像和坏死。瘤细胞核大小形态均不一致,有的呈肾形,部分似乎可见核沟,核仁不明显。根据这个图像,首先考虑为 Langerhans 细胞肉瘤。可行CD1a、S-100、Langerin标记 鉴别诊断:恶性黑色素瘤 S-100、HMB45 差分化癌 AE1/AE3、EMA 恶性纤维组织细胞瘤 CD68 组织细胞肉瘤;间变型淋巴瘤 ALK、CD30、CD15 |
再次学习,并参考了陈国璋教授的讲课资料。
如果是淋巴造血系统肿瘤:
LARGE CELL HEMATOLYMPHOID NEOPLASMS: Main considerations
--Diffuse large B-cell lymphoma
--Anaplastic large cell lymphoma
--T or NK cell lymphoma predominated by large cells
--Anaplastic plasmacytoma / plasmablastic lymphoma
--Classical Hodgkin lymphoma predominated by large cells
==Histiocytic / dendritic cell neoplasm
==Pleomorphic variant of mantle cell lymphoma
