目的 :进一步认识放线菌病的发生、发展及临床病理特征。方法 :用常规石蜡切片、HE染色法。结果 :发现放线菌病发生在盆腔时 ,常有类似于恶性肿瘤的临床病理特征。结论 :应与恶性肿瘤相鉴别 ,尤其在放线菌感染后的慢性期。术中作快速病理检查是关键 Objective: To further understand the occurrence, development and clinicopathological features of actinomycosis. Methods: Using conventional paraffin sections, HE staining. Results: Actinomycete found in the pelvic cavity, often similar to the clinicopathological features of malignant tumors. Conclusion: It should be differentiated from malignant tumors, especially in the chronic phase of actinomycetes infection. Intraoperative rapid pathological examination is the key
