PLEXIFORM NEUROFIBROMA, REPORT OF A CASE

この論文をさがす

説明

The authors report a case of plexiform neurofibroma in a 16-year-old male. The tumor in the lateral neck deriving from a peripheral, nerve sheath was as large as a fist of man with dendrite extension into the surrounding tissue, which made complete removal difficult. The tumor did not accompany neurofibromat osis.<BR>Histopathological examination revealed neoplastic hyperplasia of the nerve fascicles associated with hyperplasia of the perineurium.<BR>Higher magnification showed hyperplasia of Schwann cells, fibroblasts and collagen fibers.<BR>This rare tumor is known for its high incidence of recurrence with proximal extension along the nerve, which occasionally cause compression of the spinal cord or central nervous system leading to grave consequences.
