Oncoplastic breast surgery combining partial mastectomy with immediate breast reshaping using a keyhole-shaped skin glandular flap for Paget's disease.

Oncoplastic breast surgery (OBS), which combines the concepts of oncologic and plastic surgery, is becoming more common worldwide. We herein report the results of OBS in Japanese patients with Paget's disease. We performed OBS combining partial mastectomy with immediate breast reshaping using a keyhole-shaped skin glandular flap in two patients. In these two patients, who were diagnosed as having Paget's disease with a restricted intraductal component in the central area of their non-ptotic breast, we performed oncoplastic surgery combining partial mastectomy with immediate breast reshaping using a keyhole-shaped skin glandular flap. Neither of the two patients received contralateral surgery to produce symmetrical breasts. The observation period ranged from 6 to 12 months, and the bilateral breast volumes and inframammary lines were symmetric. OBS combining partial mastectomy with immediate breast reshaping using a keyhole-shaped skin glandular flap was successfully performed in two patients with Paget's disease.
