A 19 year old man came to our clinic in June 1977, complaining of a lmup in the left back. At the time of operation it was noted that the growth involved the M. longissimus. The tumor was excised wildely and proved to be a desmoid on pathologic examination. No recurrence was found 1 year after surgery.
