borderline ovarian tumors, giagnosis, conservative treatment, follow-up.

Borderline ovarian tumors represent 15 to 20% of ovarian tumors and affect young women for whom fertility preservation is an important therapeutic challenge. Radiological and biological examination oriented preoperative diagnosis. However, surgical exploration and histological examination make the diagnostic. The treatment for the early stages should be as conservative as possible for young patients. This is a retrospective study of 22 observations diagnosed and treated at the department of Gynecology and Obstetrics 1 of University Hospital Hassan II in Fes over a period of 8 years.The average age of our patients was 39 years, 50% were nulliparous. 95,5% of our patient complain about abdominal pelvic pain and 45.5% of patients have an increase abdominal volume. 73% of patients had clinically palpable pelvic tumors. Pregnancy was the circumstance of discovery in tow patients. The supra-pubic pelvic ultrasound was performed in all our patients. The average size of the masse is 114mm. Histological Study Shows borderlineserous tumor in 63,6%, and mucinous tumors in 27,3%. 45 % of our patients underwent conservative surgery, and 55% patients underwent radical surgery. Three patients had regular follow-up in oncology with a favorable evolution. Tow patients received adjuvant chemotherapy for the presence of invasive peritoneal implants. Eleven patients received regular follow the gynecology department with a favorable evolution. One of patients, who benefited from a conservative treatment spontaneously fell pregnant after primary infertility of 7 years. Seven patients had loosed from regular surveillance. Borderline ovarian tumors usually occur in young patients. The clinical presentation, the prognosis and the treatment are different from ovarian adenocarcinomas. They are often diagnosed at stage I of the FIGO classification. Their prognosis is excellent with a survival rate after 5 year of 95%.
