目的探讨宫颈粒细胞肉瘤(Granulocytic sarcoma，GS)的临床病理学特征、诊断及鉴别诊断。方法对1例罕见的宫颈GS的临床资料、组织学形态、免疫组化标记及治疗和预后进行分析，并复习相关文献。结果该例以宫颈肿块为首发表现，镜下肿瘤细胞呈弥漫性分布，细胞小至中等大小，胞质较少而淡染，核圆形，椭圆形，染色质细腻，核分裂象易见。免疫组化标记肿瘤细胞MPO、CD43、Lysozyme和CD34(+)。结论宫颈GS是一种罕见肿瘤，易误诊为恶性淋巴瘤和低分化癌，研究宫颈粒细胞肉瘤的临床就病理学特征有助于对该病正确认识，避免误诊及不恰当的治疗。“,”Objective To study the clinical and pathologic features, diagnosis and dif erential diagnosis of granulocytic sarcoma of the uterine cervix.Methods The clinical manifestations, histopathological features,immune-histochemistry, treatment and prognosis were analyzed in one case of GS of the uterine cervix with review of the literatures.Results One case of GS presented a cervical mass as a primary manifestation.Microscopical y,The nuclei were round and had finely dispersed chromatin.The mitotic rates were visible.Histochemical stains for MPO,CD43,Lysozyme,and CD34 were positive.Conclusion GS of the uterine cervix is rare.GS may be misdiagnosed as lymphoma and poor dif erentiated carcinoma.Wel familiar with the clinical features and pathological characteristics wil be of great help to understand this disease,and avoid misdiagnosis and potential y harmful therapies.
