Recurrence of Primary Breast Angiosarcoma 7 Years after Mastectomy in a 17-Year-Old Woman: A Case Report

Abstract

Background: Primary breast angiosarcoma is a rare neoplasm; breast angiosarcoma patients under 20 years old are extremely rare. The prognosis is often poor due to a high relapse rate after surgical resection. Case Report: We report on a case of a 17-year-old woman suffering from a primary breast angiosarcoma, associated with the local recurrence of a right-breast angiosarcoma 86 months after mastectomy. She received extensive local excision and transplantation of an adjacent skin flap. The post-operation diagnosis was angiosarcoma of histological grade III. Conclusions: This is a rare case as the patient was below 18 years old and the follow-up was greater than 5 years. Taken together, long-term close follow-up is extremely important, regardless of how long after surgery and the status of the surgical margins.
