They are classified as a fibroepithelial tumor by ICD-O, but not by MeSH. Malignant phyllodes tumours behave like sarcomas and can develop blood-borne metastases. periductal stromal tumor breast pathology outlines These rare fibroepithelial lesions display a biphasic morphology, characterized by a cellular stroma surrounding benign ducts. There are usually multiple nodules, often separated by fat, within infiltration of tumour into the fat. the histologic features of periductal stromal sarcoma were defined as 1) a predominantly spindle cell stromal proliferation of variable cellularity and atypia around open tubules and ducts devoid of a phyllodes pattern, 2) one or more often multiple nodules separated by adipose tissue, 3) stromal mitotic activity of 3/10 high power fields, and It is characterized by proliferation of atypical spindle cells .
