SPINAL TUMORS-03 MALIGNANT PHYLLODES TUMOR OF THE BREAST WITH METASTASIS TO THE THORACIC SPINE: A CASE REPORT

Malignant phyllodes tumors (MPT) of the breast are rare, and spinal metastasis from these tumors is even rarer. We present a case report of a 37-year-old female with a breast mass, who was diagnosed with malignant MPT after incisional biopsy. The patient underwent a right partial mastectomy, and negative margins were reported. However, two weeks later, the patient presented to the emergency department with severe back pain, paresthesia, and lower limb weakness. Neurosurgery consultation led to a diagnosis of T4 pathological fracture, spinal tumor and spinal cord compression, likely due to metastasis from the breast mass. Chest abdomen and pelvis CT revealed no other lesion except the T4 compression fracture. The patient underwent cord decompression tumor resection, and transpedicular fixation of T3-T5 with T4 vertebroplasty. Histopathological analysis confirmed that it was a metastasis from phyllodes tumor. Our case report highlights the importance of early detection and management of MPT, as well as the need for close follow-up and monitoring of patients with a history of breast masses it also highlights the importance of considering malignant phyllodes tumors as a differential diagnosis for breast masses and the potential for metastasis to the spine.
