[Prosthesis edge nodule and verrucous hyperplasia in leg amputees].

Dermatologic problems in leg amputees mainly result from their specific prosthetic supply. As this relationship is not well documented in the German language literature, we try to illustrate important pathophysiologic aspects of lower and upper limb prostheses in two highly characteristic dermatoses, epidermoid cysts and verrucous hyperplasia (papillomatosis cutis lymphostatica). Their management includes improvements in prostheses' workmanship and conceptional changes (e.g. CAT-CAM-technique). Interdisciplinar diagnostic and therapeutic efforts particularly between orthopedic surgeons, prosthetists and dermatologists should prevent immobility of the amputee at an early stage.
