Abstract

The World Organization (WHO) 2018 histopathological classification of breast tumors, in the group Fibroepithelial Tumor and Hamartomas there are Phyllodes tumors (tumors have original of epithelial fibers cell). This type of breast tumor is uncommon, accounting for <1% of all breast tumors. They can appear in 3 forms: Benign, marginal and malignant; and is usually found in women between the ages of 42 and 45. Approximately 16% to 30% of Phyllodes tumors are malignant. In the breast, malignant neoplasms usually grow rapidly but often metastasize late, mainly to the lungs. We report a case of Phyllodes tumor in a 62-year-old female patient, who underwent mastectomy of breast tumor 15 years ago (histopathology is unknown), and now has lung metastases and pneumothorax. The patient underwent laparoscopic surgery to treat pneumothorax and remove the lung tumor for pathology. The results of histopathology and immunohistochemistry confirmed phyllodes tumor lung metastasis.
