title: Sciatic endometriosis diagnosed by computerized tomography-guided biopsy and CD10 immunohistochemical staining.
abstract: OBJECTIVE
  To report a case of sciatic endometriosis diagnosed by computerized tomography (CT)-guided biopsy in combination with CD10 immunohistochemical staining.
  
  
  METHODS
  Case report.
  
  
  METHODS
  University hospital.
  
  
  METHODS
  A 33-year-old Japanese woman complaining of right-sided sciatica.
  
  
  METHODS
  Transgluteal computerized tomography (CT)-guided needle biopsy of a mass in the course of the right sciatic nerve was conducted for a histologic diagnosis.
  
  
  METHODS
  Histologic study with hematoxylin and eosin staining and CD10 immunohistochemical staining was performed.
  
  
  RESULTS
  Computerized tomography-guided biopsy was performed without any complication. CD10 staining distinguished endometrial stromal cells.
  
  
  CONCLUSIONS
  Computerized tomography-guided biopsy followed by CD10 immunohistochemical staining is a minimally invasive procedure for accurate diagnosis of sciatic endometriosis.
