Aggressive malignant phyllodes tumor of breast with omental metastases - A case report

Distant metastasis from malignant Phyllodes tumour (PT) is rare. They generally metastasize to the lung, bone, pleura, and liver. We present a very rare case of a 25-year-old woman with intraabdominal metastases from malignant phyllodes tumour of the breast. She presented with left breast lump and the biopsy was Phyllodes tumour. She underwent a two staged surgery; left modified radical mastectomy followed by left latissimus dorsi musculocutaneous flap cover. She received adjuvant radiation therapy to left chest wall. Following which she developed intrabdominal mass which was proven to be metastasis from Phyllodes tumour. She was then advised palliative chemotherapy. Malignant Phyllodes with distant metastases has a dismal prognosis. We propose it is preferable to have a CT Thorax and Abdomen as a staging workup for patients with malignant PT to identify those with poor prognosis.
