The biopsy of the left breast was performed under ultrasound guidance, and the pathological finding indicated a malignant tumor of mesenchymal origin, otherwise known as a gigantic cystosarcoma
phyllodes [Figure 1]e.
5) The histogenesis of primary osteosarcoma of the breast has not been fully elucidated, though an origin from totipotent mesenchymal cells of the breast stroma or a transformation from a pre-existing fibroadenoma or
phyllodes tumor have been suggested.
Phyllodes tumours were seen in 2 patients from 3 rd and 4th decade of life.
Malignant
phyllodes tumor, previously known as cystosarcoma
phyllodes or periductal stromal tumor, is a lobulated and well-demarcated solid tumor with homogeneous or heterogeneous echo-texture.
20 In this study, among the lesions in grade 4A, there were 13 cases of benign lesions including two cases of adenoma, five cases of adenoma fibrosum, two cases of intraductal papilloma, one case of mastitis, one case of breast
phyllodes tumor, one case of hyperplasia of mammary glands and one case of granulomatous inflammation and seven cases of malignant lesions.
The diagnosis of
phyllodes tumour was missed in these cases.

Phyllodes tumor (PT) is a relatively rare biphasic breast tumor that accounts for only 0.
As PASH may occasionally adopt a solid fascicular growth pattern, it can be confused with pure mesenchymal spindle cell lesions (myofibroblastoma; leiomyoma; and fibromatosis) or fibroepithelial lesions (fibroadenoma; hamartoma; and
phyllodes tumors) containing a spindle cell component [11,12].
These findings were very similar to a
phyllodes tumor of the breast.
13) The main histologic differential diagnoses for DFSP are metaplastic carcinoma, fibromatosis, myoepithelioma, and
Phyllodes tumor.
