[Von Recklinghausen's neurofibromatosis with rectal involvement]

Per-rectum bleeding was noted in a 71-year-old woman known to have neurofibromatosis. At rectoscopy, a malignant looking tumour was seen, beginning at 8 cm from the anal sphincter. It protruded into the lumen, disintegrating at its centre and oozing blood. Histological examination of the biopsy revealed a neurofibroma, without evidence of malignancy. It was possible to perform a deep rectum resection with continence-preserving end-to-end anastomosis and complete removal of the neurofibroma.
