神经鞘瘤是周围神经末稍的神经鞘源性肿瘤,可以发生在身体任何部位的末稍神经,而发生在胃者较为罕见。病理学上,以往与神经纤维瘤相混,现在已明确分开,命名为神经鞘瘤(Neurilemmoma,或Schwannoma)。我们遇到一例胃恶性神经鞘瘤,在X线表现上酷似平滑肌瘤,手术前曾诊断为平滑肌肉瘤,现报告如下。 Schwannomas are nerve sheath tumors of the peripheral nerve endings that can occur in any part of the body’s peripheral nerves, whereas those that occur in the stomach are rare. Pathologically, in the past, it was mixed with neurofibromas and it has now been clearly separated and named Neuroilemmoma (or Schwannoma). We have encountered a case of malignant gastric schwannomas, which resemble leiomyomas on X-ray findings and had leiomyosarcoma diagnosed before surgery. The report is as follows.
