An immunoperoxidase technique for the detection of carcinoembryonic antigen was applied to 10 cases of granular cell myoblastoma. Consistent, strong, intracytoplasmic granular staining, which can be easily interpreted, was obtained in all cases. Schwannomas, neurofibromas, dermatofibromas, and leiomyomas were negative. The test is helpful in confirming doubtful cases. The results tend to support the suggestion that granular cell myoblastoma is derived from perineural rather than endoneural cells.

一种用于检测癌胚抗原的免疫过氧化物酶技术应用于10例颗粒细胞瘤。所有病例均获得一致、强烈的胞浆内颗粒染色，易于解读。神经鞘瘤、神经纤维瘤、皮肤纤维瘤和平滑肌瘤均为阴性。该检测有助于确诊疑难病例。结果倾向于支持颗粒细胞瘤起源于神经周细胞而非神经内膜细胞的观点。
