Approximately 10% of patients with phyllodes tumours develop distant metastases and this can go up to 20% in patients with histologically malignant tumours. if (flag == 'play') { [17], This is predominantly a tumor of adult women, with very few examples reported in adolescents. [11] Other than surgery, there is no cure for phyllodes, as chemotherapy and radiation therapy are not effective. It is characterized by proliferation of atypical spindle cells . It is a challenge to diagnose the phyllodes by conventional trucut biopsy technique. The tumor is circumscribed. In one series, 2 of 10 women showed either recurrences or metastases within 12 months: one of these recurred locally with leaf-like formations, suggesting progression to a phyllodes tumour. An extremely rare entity, the PST is actually classified as a subtype of phyllodes tumor, with specific criteria that are only found upon histological examination of the specimen.
