title: Abdominal wall endometrioma: Our experience in Vladimir, Russia.
abstract: BACKGROUND
  Endometriosis is defined as an estrogen-dependent, benign inflammatory disease characterized by the presence of ectopic endometrial implants. Abdominal wall endometrioma (AWE) being a rare entity is a benign tumor defined as ectopic functional, endometrial tissue located in the abdominal wall.
  
  
  METHODS
  A retrospective study of 23 female patients treated with AWE in four departments of three centers in Vladimir city, Russia, from January 2010 to December 2014 was performed.
  
  
  RESULTS
  In twenty patients (87%), AWE was symptomatic, and in three patients (13%), AWE was asymptomatic. Esquivel triad presented in 17 patients (74%), and modified Esquivel triad existed in 20 patients (87%). All 23 patients were operated, and AWE excision was performed. Recurrence occurred in 4 cases (17.4%) and was associated with postoperative pain and seroma.
  
  
  CONCLUSIONS
  Postoperative pain for more than 7 days and seroma (on ultrasonography) seem to be associated with recurrence of AWE.
