[Elastofibroma cutis].

A 9 year old boy sought medical attention because of a cutaneous infiltrate of the nape that could not be diagnosed macroscopically. Microscopic examination showed it to be a fascicular fibroma of a special structure. The striking feature of the stroma was the distinct proliferation and degeneration of the elastic fibers. The alteraions of the elastic tissue are similar to those seen in elastofibroma dorsi. It is discussed if the lesion results from a hyperplasia of true elastic or/and pseudo-elastic fibers.
