Diagnostic challenges of benign breast phyllodes tumour: A rapid-growing tumour during pregnancy caused breast loss. A case report. (May 2021) - Pankratjevaite, Lina
Highlights: Phyllodes tumours are rare breast neoplasms. Inadequate treatment of phyllodes tumour can result to tumour recurrence, growth or metastatic spread, when tumour has malignant potential. In suitable cases, skin-sparing mastectomy with immediate silicone implant reconstruction might be a treatment option. The patients with microscopically radical removed benign phyllodes tumours can be followed up with annual surveillance. Abstract: Introduction: Phyllodes tumours are rare breast neoplasms. It is especially rare in pregnancy. Presentation of case: We report a case of a 37-year-old woman with left breast benign phyllodes tumour, which started to grow very fast during pregnancy. The tumour was too big for breast-conserving surgery and it was necessary to remove the whole left breast. Patient underwent successful nipple-skin-sparing mastectomy with immediate silicone implant reconstruction. Conclusion: Breast phyllodes are classified as benign, borderline, and malignant. Standard treatment of breast phyllodes is surgery. The choice of surgery type depends on the tumour factors and breast size. We highlight that, inadequate treatment of phyllodes tumour can result to recurrence, growth, or even metastatic spread, when tumour has malignant potential.
