Dermatofibrosarcoma protuberans (DFSP) is a locally aggressive, rarely metastatic, spindle cell tumor. Trauma has been associated with its development.

We report a case of DFSP occurring in a smallpox vaccination scar and review the available literature. (J Am Acad Dermatol 2003;48:S54-5.)Le texte complet de cet article est disponible en PDF.
