Patients and methods: This is a retrolective descriptive study conducted during the period from 3 April 2017 to 3 April 2019, the Gynecologic Breast pole of the Oncology National Institute of Rabat. Results: Out of 105 files listed, the locations of the tumours were: 35% 37/105 QSE, QSI QSE + 21/105 or 20%, QSI 19/105 or 18%, QSI 12/105 or 11%, other maps 16/105 or 16%. The techniques were Oncoplastic: Pamectomy 10/105 or 10% Round Block 58/105 or 55%, plasty inverted T 21/105 or 20%, and other technical 16/105 or 15%. The aesthetic results and the quality of resection were correct and above all stable at 82/105 patients 78% of cases. The lymphocele 13/105 or 12% 5/105 5% lymphoedema represented early complications occurred as late complications consisted of retractile unsightly scars 15/105 or 14%, breast asymmetry 13/105 soit12% and cutaneous sclerosis 3/105 or 3%. Conclusion: The oncoplastic surgery is a part of multidisciplinary management of breast cancer. It imposes oncologic resections and reassuring cosmetic results for the patient and the practitioner.展开更多
