Primary malignant fibrous histiocytoma of the jejunum metastatic to the spine: report of a case.

We report a case of malignant fibrous histiocytoma (MFH) metastatic to the spine. A 41-yr-old male was admitted to our hospital for radiation treatment of MFH of the spine. He began to show signs suggestive of partial small bowel obstruction. Computed tomography demonstrated jejuno-jejunal intussusception. The patient was taken to the operating room, where the diagnosis was confirmed. Partial jejunal resection was performed. The lead point of the intussusception was histologically diagnosed to be a high-grade malignant fibrous histiocytoma. We believe that the spinal lesion was the metastatic lesion and that metastasis occurred via the vessels of Adamciewicz. To our knowledge this is the first case thus reported.
