Primary malignant schwannoma of the small intestine is an extremely rare disease. We report a primary malignant intestinal schwannoma of the small bowel in a 66-year-old woman, who was admitted to the hospital because of fatigue and anaemia. On clinical examination there was a solid mass at the abdomen. Ultrasound scanning showed an abdominal tumour. Computed tomography showed a mass in the area of the pancreatic tail involving the small intestine. At laparotomy a 10 x 10 cm tumour was found in the proximal jejunum, and 50 cm of the small intestine was resected. The histology of the lesion corresponded to a malignant intestinal schwannoma. The results of previous studies and of our report suggest that the diagnosis of malignant intestinal schwannoma may be difficult, and to exclude malignant conditions laparotomy and surgical excision of the tumour are adequate in the management of this type of lesion.
原发性小肠恶性施万细胞瘤是一种极其罕见的疾病。我们报告了一名66岁女性的原发性小肠恶性施万细胞瘤，她因疲劳和贫血入院。临床检查发现腹部有一个实性肿块。超声扫描显示腹部有肿瘤。计算机断层扫描显示胰尾区域有一个肿块累及小肠。剖腹手术时，在空肠近端发现一个10×10厘米的肿瘤，切除了50厘米的小肠。病变的组织学符合恶性小肠施万细胞瘤。先前研究和我们报告的结果表明，恶性小肠施万细胞瘤的诊断可能困难，对于这类病变的处理，剖腹手术和肿瘤切除足以排除恶性情况。
