Virchow, in 1864, was the first to recognize that tumors of the suprarenal medulla which metastasize to the liver are neurogenic and to refer to them as gliomas. Marchand,1 in 1881, following the line of thought initiated by Virchow, reported suprarenal tumor in a 9 year old child and called it a glioma. In 1907, Marchand2 reported the first authentic case on record of a neurocytoma of the gasserian ganglion. Since then, tumors of the neurogenic type have been described from time to time.
They are known to occur in any place where nerve tissue is present, as in the brain, the retina, the gasserian ganglion, the spinal cord, the abdominal sympathetic system and the suprarenal medulla.
Pepper,3 in 1901, described a tumor of the suprarenal medulla which he believed to be a lymphosarcoma. The growth, he thought, appeared soon after birth and gave rise to diffuse
