A retrospective review of all patients who underwent surgery for an anterior abdominal wall mass which confirmed by pathology examination as an endometrioma will be completely performed. The clinical data will be recorded and pathology report diagnosis will be correlated with the clinical data to assess the possible causes of endometrioma in the women treated in our tertiary hospital and the efficacy of the surgical excision.

Our hospital is a tertiary center for performing Cesarean sections, external endometriosis (Endometrioma) is a challenging complication for this operation, many treatment choices are available and the most common is the surgical excision, however recurrence could be seen after the surgical operation. We assess all patients who underwent surgical excision for abdominal wall endometriomas in our hospital by retrieving the medical files and pathology reports to study the possible age group,causes and duration of endometriomas. Also the rate of enodmetriomas among the previously experienced females with cesarean section operations. Pathological diagnosis tools will be also assessed.

Ethical approval was obtained from the local committee. Results will be statistically assessed using SPSS programm.
