Witzel has recently shown that in many casesthe neuroma is found attached to the end of the bone in the tumor presents itself in the form of a bulbous enlargement of theend of the nerve, which closely resembles a spring onion in outline(Fig. 371). Cross-sections of such tumors show the numerical increaseof myelinic nerve-fibres (PI. 12, Fig. i). Under the same influence thefibroblasts proliferate and greatly increase the amount of connectivetissue, producing thus a true neurofibroma. In the majority of casesthe tumor is limited and forms the bulbous extremity of the nerve;in some instances, as in the case reported by Haycm and Gilbert, thenerve is at this time enlarged for a very considerable distance, theenlargem
