title: Signet ring stromal tumor of the ovary occurring in conjunction with brenner tumor.
abstract: OBJECTIVE
  A case is presented of a single ovarian mass that had elements of both signet ring stromal tumor of the ovary and Brenner tumor.
  
  
  METHODS
  The histologic features and the results of histocytochemical, immunohistochemical, and electron microscopic studies are presented.
  
  
  RESULTS
  The signet ring component of the mass demonstrated features consistent with the few other cases previously reported. A positive immunohistochemical stain for the peptide hormone inhibin provides additional evidence for an ovarian stromal origin for this tumor.
  
  
  CONCLUSIONS
  The tumor produced no hormonally related symptoms and has shown no evidence of recurrence. Signet ring stromal tumor of the ovary is an uncommon benign tumor that may be confused with metastatic signet ring carcinoma. The significance of the signet ring cells is not certain. Their association with Brenner tumor has not been previously described.
