INTRODUCTION: @entity11003 is a rare @entity5 of smooth muscle origin. It has been reported in many anatomical sites, but it usually affects limbs. It's recurrence rate is slow but it's quite difficult to make diagnosis. CASE REPORT: The study describes the case of a 53-year-old @entity1 , with a subcutaneous, large @entity11003 of the right clavicular region. The @entity1 had a @entity158 , slow-growing mass, measuring more than 20 mm. The mass had a relatively homogeneous, hypoechoic-echo texture, with a small amount of posterior acoustic enhancement. No diagnosis was made and the @entity1 underwent surgery for a suspected leyomioma. After surgery a hard, round-shaped @entity5 , measuring approximately 43 x 32 mm of diameter was found with histological features of leyomioma. DISCUSSION: The case has an unusual clinical presentation, for the uncommon localization and size of the mass. US imaging and histopathologic features are reported. The rarity of @entity11003 makes diagnosis difficult and frequently delayed. Differential diagnosis includes @entity281 , @entity5 , @entity2695 , @entity14325 , @entity4494 , and @entity130 . CONCLUSIONS: This report highlights that @entity2909 , even of large dimension, must be included in the differential diagnosis of @entity158 , subcutaneous masses.
