Breast Reconstruction After Resection of Bilateral Giant Phyllodes Tumors: Two Separate Deep Inferior Epigastric Perforator Flaps From One Donor Site

Abstract

Abstract Background Reports of synchronous bilateral giant (>10 cm) phyllodes tumors of the breast are scant in the literature. Reconstruction of the two large defects created after bilateral mastectomies is a challenge. Our patient, a 45-year-old woman, had a borderline phyllodes tumor measuring 15.5×15×7.3 cm in the right breast and a malignant phyllodes tumor measuring 16×10×9.8 cm in the left breast. After bilateral mastectomy, the following two huge defects remained: a 15×15 cm defect in the right breast and a 18×15-cm defect in the left breast. Methods We used one donor site with two separated deep inferior epigastric perforator flaps for postmastectomy breast reconstruction. This is the first case of bilateral giant phyllodes tumor in which mastectomy was followed immediately by autologous tissue reconstruction. Results Large flap reconstruction conferred adequate leverage for wide excision of giant phyllodes tumors, and no local recurrence or distal metastatic lesions were observed over a follow-up period of 4 years. Conclusions This method caused less donor site morbidity than did methods involving other types of flaps, and good functional and cosmetic results were achieved.
