چکیده

The transformation of a benign fibroadenoma into a phyllodes tumor is uncommon and unpredictable. We report the case of a 40-year-old woman with a core biopsy proven fibroadenoma that underwent transformation into a malignant phyllodes tumor after 3 years of size stability. We present ultrasound and magnetic resonance images, as well as pathology slides from core biopsy and surgical excision, to illustrate this transformation. It has been suggested that phyllodes tumors may be misdiagnosed as fibroadenomas by core biopsy. However, in this case, pathology supports correct initial diagnosis of fibroadenoma and demonstrates a portion of the original fibroadenoma along the periphery of the malignant phyllodes tumor.

Phyllodes tumor is an extremely rare tumor of the breast. It occurs in females in the third and fourth decades. The difficulty in distinguishing between phyllodes tumors and benign fibroadenoma may lead to misdiagnosis. Lymph node involvement is rarely described in phyllodes tumors; for this reason, sentinel node biopsy may be warranted. We present a case of a 33-year-old woman affected by huge...

Stromal CD10 expression in mammary fibroadenomas and phyllodes tumours.

BACKGROUND/AIMS CD10 (CALLA) has recently been reported to be expressed in spindle cell neoplasia, and has been used to differentiate endometrial stromal sarcoma from leiomyoma and leiomyosarcoma. In the breast, myoepithelial cells express CD10, but there are few studies of the expression of CD10 in mammary fibroepithelial lesions. METHODS Stromal CD10 expression was studied in 181 mammary ph...

Phyllodes tumor is an uncommon fibro epithelial breast tumor with diverse biological behavior. The tumor closely resemble as fibroadenoma of the breast. On one end phyllodes is slow growing benign tumor, the other end tumor grows rapidly behave like sarcoma which metastasizes, and phyllodes can turn to frank sarcoma. Tumor can be diagnosed on clinical basis i.e. large mass with lobulated (bosse...
