KEESE, M. et al. Acute GI bleeding by multiple jejunal gastrointestinal autonomic nerve tumour associated with neurofibromatosis type I. Rev. esp. enferm. dig. [online]. 2007, vol.99, n.10, pp.608-611. ISSN 1130-0108.

We describe a surgical emergency due to GI-bleeding caused by gastrointestinal autonomic nerve tumours (GANT's) in a patient with von Recklinghausen's disease. A 72 year old female patient with von Recklinghausen's disease was admitted with maelena. Endoscopy showed no active bleeding in the stomach and the colon. Therefore an angio-CT-scan was performed which revealed masses of the proximal jejunum as source of bleeding. Laparotomy was indicated and a 20 cm segment of jejunum which carried multiple extraluminal tumours was resected. The source of the bleeding was a 2 cm tumour which had eroded the mucosal surface. Immunohistologically, evidence of neuronal differentiation could be shown in the spindle-formed cells with positive staining for C-Kit (CD 117), CD 34, and a locally positive staining for synaptophysine and S100. This case report illustrates the association between neurofibromatosis and stromal tumours and should alert surgeons and gastroenterologist about gastrointestinal manifestations in patients with von Recklinghausen's disease.

Palabras clave : Gastrointestinal autonomic nerve tumours; von Recklinghausen's disease; Stromal tumors; Gastrointestinal bleeding.
