Oncoplastic breast surgery (OBS), which combines the concepts of oncological and plastic surgery, is becoming more common, especially in Western countries; however, only a few reports have been published in Japan. We herein report the results of OBS for Japanese patients with early breast cancer in the upper quadrant. We performed oncoplastic surgery combining partial mastectomy using a periareolar incision with immediate breast reshaping using a crescent-shaped cutaneous flap in three patients with a past history of breast-feeding, ptotic breasts and lesions that were suitable for breast conserving surgery. The lesions were located in the upper quadrant and were 5, 6 and 10 cm from the nipple, respectively. The total length of the operations ranged between 86 and 192 min, with the mean being 164 min. Two patients underwent contralateral surgery to produce symmetrical breasts and one did not. The plastic period after receiving pathological results intraoperatively ranged between 47 and 120 min, with the mean period being 82 min. The observation period ranged between 6 and 12 months, and the cosmetic results were excellent in all three cases. OBS combining partial mastectomy using a periareolar incision with immediate breast reshaping using a crescent-shaped cutaneous flap was successfully performed in patients with early cancer in the upper quadrant.
