This last condition, however, maybeaccidental; the result of external injury. And probably it is so ; forthe structure, in all other respects, seems to be simple and difference from the neuroma is, that whereas in the latter thenervous fibres are very apparent, here the fibrous matter seems to be PAINFUL TUBERCLE. 591 mainly, if not wholly, a new production. No nervous trunk is continu-ous with the mass ; only the minute terminal branches are capable ofbeing traced into it. The tumour is very movable ; gliding under the Fie. finger. But it is intolerant of the slightest pressure ; intense painbeing produced thereby. The pain sometimes assumes the form ofparoxysms ; induced by the slightest external influence, and sometimesof spontaneous origin. More frequently than the neuroma, it has beenassociated with hysteria; but, usually, the general health is less disor-dered than in neuroma. It may occur in any part of the general sur-face ; but is most frequent in the lower extremities. Treatment is by excision. If the skin be at all involved, it is to betaken away along with the tumour, to the requisite extent, by means ofelliptical incisions. If the integument be free, a simple wound is no reproduction. Some general means may be subsequentlyexpedient, to calm the nervous system from excitement, which the exist-ence of the tumour may have induced.
