Life threatening bleeding from untreated phyllodes tumor following earthquake induced follow up delay

Phyllodes tumors, representing 0.3%–0.5% of breast masses, are infrequent and sophisticated neoplasms of the breast. Based on their histological features, they are classified into three categories: benign, borderline, or malignant; preoperative diagnosis is challenging, and surgical removal with clear margins is the primary treatment option. This report describes the case of a 35-year-old woman whose longstanding breast mass underwent rapid transformation. The patient missed her follow-up appointment due to the February 6, 2023, earthquake in Hatay and presented with hemorrhagic shock from bleeding caused by the tumor eroding the internal thoracic artery.
