Sciatic endometriosis diagnosed by computerized tomography-guided biopsy and CD10 immunohistochemical staining.
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.
