title: Gastro-intestinal bleeding caused by leiomyoma of the small intestine in a child with neurofibromatosis.
abstract: Gastro-intestinal bleeding is an uncommon presentation in children with neurofibromatosis. Gastro-intestinal involvement caused by jejunal leiomyoma has only been described in adults. To the best of our knowledge, this is the first paediatric case of jejunal leiomyoma associated with neurofibromatosis. We present a 10-year-old girl with a 9-month history of anaemia and low gastro-intestinal bleeding. Abdominal sonography and small bowel series showed a submucosal mass in the proximal jejunum. On surgery, a submucosal tumour was excised and histological examination suggested a diagnosis of "smooth muscle tumour of undetermined malignant potential". There were no recurrence of symptoms for 4 years after the operation.
  
  
  CONCLUSIONS
  Jejunal leiomyoma should be considered in a child with neurofibromatosis presenting with gastro-intestinal bleeding.
