Thymic carcinoma is an unusual neoplasm, and the undifferentiated type is rare. Thymic carcinoid is also rare. This report describes a patient with coexisting undifferentiated thymic carcinoma and a carcinoid tumor. Both lesions were completely excised. The carcinoid cells showed argyrophilic granules by Grimelius' method and immunoreactivity against neuron-specific enolase, whereas the undifferentiated carcinoma cells were negative for argyrophilic stain and immunostaining against neuron-specific enolase.
胸腺癌是一种罕见的肿瘤，未分化型更为少见。胸腺类癌也很罕见。本报告描述了一例同时存在未分化胸腺癌和类癌肿瘤的患者。两种病变均被完整切除。类癌细胞经格里梅利乌斯法显示嗜银颗粒，并对神经元特异性烯醇化酶呈免疫反应性，而未分化癌细胞嗜银染色及对神经元特异性烯醇化酶的免疫染色均为阴性。
