We report the unusual case of a 26\u2010year\u2010old man with an AAM presenting as a slowly enlarging scrotal mass. Gray\u2010scale scrotal sonography demonstrated a well\u2010demarcated, hypoechoic, extratesticular, extraepididymal mass with multiple thin, echogenic internal septa. The mass arose inferior to the left testicle and displaced the testicle cephalad. Color Doppler sonography revealed surrounding vascularity but no Doppler signals within the mass. The testicles and epididymides demonstrated normal echogenicity and vascularity. Histologic examination of the excised mass revealed a well\u2010demarcated, nonencapsulated lesion composed of spindle\u2010shaped cells in a myxoid background with a prominent vascular component. \u00a9 2001 John Wiley &amp; Sons, Inc.
