目的探讨原发性腹膜砂砾体癌的临床病理特点、诊断及意义。方法通过光镜和免疫组织化学方法对1例原发性腹膜砂砾体癌组织标本进行观察。结果原发性腹膜砂砾体癌细胞形态及组织结构单一,较多砂砾体存在于肿瘤组织内。免疫组化染色CK(+),vimentin(-),CA125(+),CK20(-),CK7(+)。结论原发性腹膜砂砾体癌十分罕见,肿瘤内大量砂砾体提示其可能具有较为良好的预后。
Objective To investigate the clinicopathological features, diagnosis and significance of primary peritoneal gravel carcinoma. Methods One case of primary peritoneal gravel carcinoma tissues was observed by light microscopy and immunohistochemistry. Results Primary peritoneal gravel body cancer cells with a single morphological and organizational structure, more gravel in the tumor tissue. Immunohistochemical staining of CK (+), vimentin (-), CA125 (+), CK20 (-) and CK7 (+). Conclusion The primary peritoneal gravel carcinoma is very rare, a large number of gravel in the tumor suggests that it may have a more good prognosis.
