Giant Malignant Phyllodes Tumor at a Tertiary Care Hospital of Karachi, Pakistan

Phyllodes tumor is a rare benign breast cancer that carries malignant potential. Malignant phyllodes tumors are histologically sarcomas as they originate from the connective tissue of the breast. We present a case of a 38 year old female who presented with complaints of a slowgrowing painful lump in her left breast over for one and a half year that later ruptured and became necrotic. She was operated upon with a provisional diagnosis of a fungating breast growth; however, subsequent histopathology report confirmed the tissue as a malignant phyllodes tumor.
