The malignant variant of phyllodes tumor is even lower. Some doctors feel that an even wider margin of healthy tissue should be removed (wide excision). Angiosarcomas. Hendricks JB, Wilkinson EJ (1993) Comparison of two anti- immunoreactive endothelin 1 in mammary phyllodes tumor: bodies for evaluation of estrogen receptors in paraffin-embed- possible paracrine role of endothelin 1 in the growth of stro- ded tumors. 65 In a retrospective series of 48 patients with malignant phyllodes tumors, a margin of less than 1 cm was associated with an increased risk for local recurrence, although the local recurrence rate for patients with margins wider than 1 cm was still quite .

The relative volumes occupied by epithelium and stroma in each tumor were measured . This type of tumor is called a "sarcoma," because it occurs in the connective tissue (stroma) of your breast, rather than in the tissue lining of ducts and lobes. This is a case of hypoglycemia caused by phyllodes tumor of breast, which belongs to non-islet cell tumor hypoglycemia. The tumor is immunoreactive for estrogen receptor (D) and progester-one receptor (E) but negative (1+/3) for human epidermal growth factor receptor 2 (F). In view of the rarity of this .
