It is often difficult to identify the characteristics of soft-tissue tumors
of the chest wall. This paper describes the peculiarities of elastofibroma
dorsi, a rare pseudotumor of this site, to exclude many dangerous misconce
ptions. During the period between 1987 and 1997, we treated nine patients w
ith elastofibroma dorsi, In six patients, the lesion was unilateral and in
three it was bilateral. All these lesions were excised and no evidence of l
ocal recurrence or shoulder disability was observed at the last clinical ev
aluation. Elastofibroma dorsi is a rare, slow-growing, pseudotumoral lesion
of the soft tissues of the chest wall with a peculiar radiographic and his
tologic pattern.
