Kiss Flaps to Repair Large Skin Defect After Excision of Giant Malignant Phyllodes Tumor of the Breast: A Case Report and Literature Review

Abstract

Background: Malignant phyllodes tumors of the breast are fairly rare and fast-growing tumors. They do not respond to chemotherapy or hormonal therapy except in malignant phyllodes tumors. Therefore, the primary treatment for malignant phyllodes tumors is wide surgical excision. Case presentation: Herein, we report a case study which featured a 26-year-old woman presented with a giant malignant phyllodes tumor measuring 20 × 17 × 13 cm. In order to reduce the chance of local recurrence, treatment for these types of tumors usually involves extensive excision with at least 1 cm of surgical margins. The patient underwent extended lumpectomy with 1-3 cm surgical margins, which left a large skin defect of 25 × 15 cm. Repair of such a large skin defect is a challenge to breast surgeons. This is the first reported case in which a “kiss” flap was successfully used to repair the skin defect created after resection of a giant malignant phyllodes tumor.Conclusions: The kiss flap could be considered as an effective method to repair large chest wall defects after resection of giant phyllodes tumors.
