Abstract

Elastofibroma is a rare entity of slowly-growing, solid, ill-defined fibroblastic mass occurring almost exclusively in elderly persons and arising mainly from the connective tissue between the lower portion of the scapula and the chest wall. This entity has been considered to be a degenerative pseudo-neoplastic process caused by mechanical friction. We report an additional case of elastofibroma removed from the subscapular region of a 58-year-old woman. Microscopically the tumor was made up of a mixture of swollen eosinophilic collagen and elastic fibers occasionally associated with fibroblasts and mature fat cells. The elastic fibers showed a degenerated beaded appearance or were fragmented into small globules or droplets in a linear pattern.
