title: Clinical and Sonographic Evaluation of a Lower Extremity Angioleiomyoma in a 52-Year-Old Woman.
abstract: OBJECTIVE
  The purpose of this case study is to describe the role of sonographic examination in the initial evaluation of an angioleiomyoma and to discuss the characteristic findings associated with this soft tissue mass.
  
  
  METHODS
  A 52-year-old woman presented with a large, tender, erythematous mass on the anterolateral aspect of her right knee. Sonographic examination revealed a highly vascular mass within the subcutaneous tissues. Differential considerations included benign soft tissues masses such as angioleiomyoma and hemangioma.
  
  
  RESULTS
  Surgical consultation was recommended. Excisional biopsy was performed. Histopathological examination confirmed the diagnosis of angioleiomyoma.
  
  
  CONCLUSIONS
  Although ultrasonographic findings of a superficial soft tissue mass may be nonspecific, when a highly vascular, well-defined, slow-growing mass is present, angioleiomyoma should be included in the differential diagnosis.
