Breast phyllodes tumors are rare mesenchymal tumors, often accompanied by internal cysts, hemorrhages, infarctions, and necrosis. The tumor exhibits rapid growth, especially when infarct necrosis occurs within the tumor. In the current report, we showed a woman in her 50s who noticed a rapidly growing breast mass and received an excisional biopsy diagnosis of a phyllodes tumor with hemorrhagic infarction. Pathological diagnosis was challenging due to severe hemorrhage and necrosis; however, a comprehensive diagnosis that considered imaging tests recommended appropriate surgical treatment. Here, we report our experience and further analyze the existing literature regarding the prognostic impact of phyllodes tumors enhanced by intratumoral changes.
Keywords: breast tumor; hemorrhagic infarction; pathological diagnosis; phyllodes tumor; surgical intervention.
