A pigmented tumor was removed from the maxillar alveolar process of a 5-month-old boy. It was examined by light and electron microscopy and a diagnosis of melanotic neuroectodermal tumor was made. In addition to connective tissue, three main cell types were identified: undifferentiated (stem) cells, melanocytes, and nerve cells with processes forming an abundant neuropil. Numerous axo-dendritic and occasional axo-somatic synapses were observed. The neural component demonstrated better differentiation in this example than in any reported so far.
从一名5个月大男婴的上颌牙槽突切除了一个色素沉着肿瘤。通过光镜和电镜检查，诊断为黑素性神经外胚层肿瘤。除结缔组织外，确定了三种主要细胞类型：未分化（干）细胞、黑素细胞和具有形成丰富神经毡的突起的神经细胞。观察到大量轴突-树突突触和偶尔的轴突-胞体突触。在这个病例中，神经成分的分化程度比迄今为止报道的任何病例都要好。
