Introduction: Periductal Stromal Sarcoma (PSS), especially spindle and epithelioid types, is a rare subtype of the malignant fibroepithelial tumor with benign ductal elements and a sarcomatous stroma composed of spindle cells. Care should be taken when considering the diagnosis of fibroadenoma based only on clinical, radiological, and biopsy findings. It is characterized by proliferation of atypical spindle cells surrounding benign mammary ducts and infiltrating adjacent adipose tissue. Some would extend the spectrum to include malignant phyllodes tumors and frank sarcoma. } Despite their rarity, PTs are an important clinical problem due to their . Introduction. This is about 15 years older than the typical age of patients with fibroadenoma, a condition with which phyllodes tumors may be confused. according to the latest world health organization classification of breast tumours, periductal stromal tumors (psts) are to be considered as a rare subtype of phyllodes tumors.
