CASE REPORT: METASTATIC PHYLLODE TUMOR

Rationale: Malignant phyllodes tumors are rare breast neoplasms that are associated with a 6.2% to 25% incidence rate of distant metastasis the lung is the most common metastatic site. To date, there is no consensus regarding the treatment of metastatic malignant phyllodes breast tumors. Patient concern: A 34-year-old woman was admitted into the gynecology department for a rapidly growing left breast tumor that was first noticed month prior. Diagnosis: Core needle biopsy revealed a malignant phyllodes tumor. A chest computed tomography tomography/CT showed metastatic lymph nodes that appeared to have spread to the right axilla She was subsequently followed by course of radiotherapy, she consulted again 3 months later for a productive cough, X-ray thorax in comparison with that made preoperatively: presence of the left peri-hilar nodules which were not present on the first X-ray Interventions: A left mastectomy with axillary lymph node dissection was conducted and a thoracoabdominal flap and a split thickness skin graft were performed for the skin defect. And radiotherapie adjuvant. Lessons: As standard treatment guidelines for metastatic malignant phyllodes tumors are lacking, we opted for the aforementioned aggressive treatments that resulted in complete remission of the lung metastasis. Therefore, aggressive treatment, whenever possible, is warranted.
