[Kaposiform haemangioendothelioma in the small intestine of a three year-old boy].

Kaposiform haemangioendothelioma is a rare, locally aggressive vascular tumour, which is mainly found in children. Typically, it occurs in the skin. The tumour is borderline malignant due to its rapid infiltrative growth. Metastasis has not been described. Since 1993, when this tumour was first defined, less than 160 cases have been reported. To our knowledge, this is the first case of kaposiform haemangioendothelioma in the gastrointestinal tract. We report a case of a three year-old boy, who presented with small bowel obstruction due to invagination of a kaposiform haemangioendothelioma.
