Elastofibroma is a rare benign tumor of soft tissues that has the elective localization in peri- or interscapular region. It is characterized by the proliferation of fibroblast-like cells which appear enveloped by abundant elastic and collagen fibers. Here we present a case of elastofibroma, observed in a 63 year old woman in the interscapular region. The neoformation has been studied by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Our hypothesis is the possibility that elastofibroma is the consequence of active neoformation of fibers elastic normal in the quality that subsequently is meet to progressive degenerative phenomenons.
