Oncoplastic management of a lower-inner quadrant breast cancer using inframammary crescent mastoplasty with an anterior intercostal artery perforator flap: a case report

Oncoplastic breast surgery aims to optimize oncologic control and cosmetic outcomes. This report presents a case of a 57-year-old woman with hormone receptor-positive invasive ductal carcinoma in the lower-inner quadrant of the left breast. A partial mastectomy with immediate reconstruction using inframammary crescent mastoplasty based on the anterior intercostal artery perforator (AICAP) flap was performed. The patient experienced a smooth recovery, received adjuvant hormonal therapy, and showed no recurrence after one year. This case highlights the underreported use of the AICAP-based crescent flap in oncoplastic reconstruction for challenging tumor locations, suggesting that this versatile technique may broaden reconstructive options and improve cosmetic outcomes in appropriately selected patients.
