[Elastofibroma dorsi].

Elastofibroma dorsi--a rare pseudotumor arising in the subscapular region in elderly people--was found twice in the biopsy specimen from women 51 and 65 years of age respectively. Another two bulky elastofibromas were displayed bilaterally in the subscapular region in a woman 85 years of age in the course of systematic examination of subscapular regions in a series of 120 autopsies. Microscopic changes similar to elastofibroma were found in 9,8 per cent in females and 6,7 per cent in males, all at least 57 years old. Bilateral changes were found 4 times. Analogous study in Finland noted much higher incidence of those so called subclinical elastofibromas (24,4 per cent in females, 11,2 per cent in males). The possible causes of differences between finnish and presented study as well as light and electron microscopic findings in elastofibroma are discussed.
