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.
Subjects and 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.
Conclusion: Postoperative pain for more than 7 days and seroma (on ultrasonography) seem to be associated with recurrence of AWE.
