摘要
目的探讨淋巴结内栅栏状肌纤维母细胞瘤的临床病理学特征及诊断、鉴别诊断要点。方法对1例淋巴结内栅栏状肌纤维母细胞瘤进行临床病理学、免疫组化及电镜研究。结果患者男性,51岁。临床上发现右腹股沟包块8年。组织学:梭形细胞交织束状、栅栏状排列,细胞之间存在石棉样纤维。免疫组化:S-100(-),FN和actin(+)。结论淋巴结内栅栏状肌纤维母细胞瘤是主要发生于成人淋巴结内的罕见的良性间叶性肿瘤,手术切除后不复发、不转移,预后良好。
Objective To investigate the histopathological features and differential diagnosis of palisaded myofibroblastoma in lymph node. Methods Clinical data analysis, morphologic investigation and immunohistochemical staining of palisaded myofibroblastoma in lymph node were performed. Results The patient was male, 51 years old, with an right inguinal cyst for eight years. Histologically, the spindle cell was in fasicle and palisaoled patterns. The amianthoid fibres were among the tumor cells, lmmunohistochemically, the tumor cells were positive for actin and FN, but negative for S-100 portein. Conclusion Palisaded myofibroblastoma in lymph node is a rare benign mesenchymal tumor. It often oecurrs among adults. After excision, prognosis is favourable without recurrent and metastasis.
