A Novel Breast-Conserving Surgical Technique in the Management of Phyllodes Tumours of the Breast.

Background Despite advances in oncoplastic breast-conserving techniques, very large phyllodes tumours (PT) may still be recommended for mastectomy. Methods We report a novel 2-staged breast-conserving technique that enables smaller excisional volumes whilst maintaining safe oncological excision. Stage-1 is a capsular dissection via a posterior glandular approach without sacrifice of native breast volume. Stage-2 is a delayed localised resection of the seroma cavity providing a circumferential "margin". Two cases are presented. Conclusion This novel technique preserves the breast, optimises cosmesis and is a safe approach to the surgical management of large PT.
