title: Epithelioid vascular leiomyoma of the uterus mimicking glomangiomyoma.
abstract: METHODS
  An unusual case of epithelioid vascular leiomyoma mimicking glomangiomyoma arising in the uterine corpus of a 55-year-old Japanese woman is presented. The surgically resected uterine mass, measuring 4.0x3.5 cm2, demonstrated a dark red well-circumscribed tumor. Histologically, the rounded epithelioid cells around the dilated vessels showed gradual transition to spindled smooth muscle cells. Immunohistochemistry was positive for smooth muscle actin, but negative for collagen IV.
  
  
  CONCLUSIONS
  The experience in this case emphasizes that glomangiomyoma-like feature is interesting and might indeed be a new histological variant of uterine leiomyomas.
