  • NeurofibromaSoft&circumscribedRoundedSlightly tenderSkin or deeper tissuesInterstitial tissue of a periferal nerveSolitary or MultipleSpinal canal

  • FibromaUncommon in extremities Never in deep tissuesFirm,Round, painless nodule Usually connected with a fascia or apponeurotic structure

  • LipomaCommonAlmost any partUsually subcutaneousSoft,often large,lobulated,with thin capsuleFat&Connective tissueLocal excision
