We describe a case of an occipital lobe primitive neuroectodermal tumor (PNET) in a 60-year-old man with immunocytochemical evidence of neuronal, glial, smooth muscle and adipose tissue differentiation in the primary tumor and its metastases. This is the first case of PNET of cerebrum in which adipose tissue and smooth muscle has been demonstrated. The possible cells of origin for these mesenchymal elements is discussed.
我们描述了一例60岁男性枕叶原始神经外胚层肿瘤（PNET），其原发肿瘤及其转移灶具有神经元、神经胶质、平滑肌和脂肪组织分化的免疫细胞化学证据。这是首例已证实存在脂肪组织和平滑肌的大脑PNET病例。文中讨论了这些间充质成分可能的起源细胞。
