Phyllodes tumours (PTs) are infrequent fibroepithelial neoplasms that account for <1% of all primary breast tumours. Local recurrence (LR) rates and distant metastasis vary depending on tumour histology. In this case report, the patient developed a painful growing tumour in the nipple after nipple-sparing mastectomy 17 years before. Local excision was performed with a final diagnosis of borderline PT after 205 months disease-free.The management of surgical margins of PT remains under discussion due to the high risk of LR. Breast-conserving surgery, when feasible, is considered the surgical approach of choice; however, immediate breast reconstruction after mastectomy is a balanced option when the tumour's characteristics are not suitable for conservative surgery. When performing nipple-sparing mastectomy, nipple recurrence is extremely rare but a complication to consider during the patient's follow-up.
