Phyllodes Tumor or Breast Fibroadenoma?
Phyllodes tumor (PT) is an uncommon and distinct category of breast cancer, being a particular form of intracanalicular fibroadenoma. A definitive diagnosis is difficult to make just based on imaging investigations and fine needle biopsy; also PTs are frequently misinterpreted as breast fibroadenomas. In the case of of a 26-year old woman with a suspected PT (based on clinical investigation) wh...
متن کاملClonal analysis of fibroadenoma and phyllodes tumor of the breast.
Clonality of fibroadenoma and phyllodes tumor of the breast was analyzed by means of the polymerase chain reaction using small DNA samples prepared from cryostat sections. The method of clonal analysis was based on restriction fragment length polymorphism of X-chromosome-linked phosphoglycerokinase gene and on differential methylation of the gene. Specimens from 10 fibroadenomas and 5 phyllodes...
متن کاملTransformation of benign fibroadenoma to malignant phyllodes tumor
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, t...
متن کاملSignificant histologic features differentiating cellular fibroadenoma from phyllodes tumor on core needle biopsy specimens.
OBJECTIVES Cellular fibroepithelial lesions (CFELs) are a heterogeneous group of tumors encompassing cellular fibroadenoma (CFA) and phyllodes tumor (PT). Distinction between the two is challenging on core needle biopsy (CNB) specimens. The objective of this study was to evaluate histologic features that can help distinguish PT from CFA on CNB specimens. METHODS Records of all patients diagno...
متن کاملGiant sized epidermal inclusion cyst of the breast initially mimicking a large fibroadenoma or phyllodes tumor
Epidermal inclusion cysts are formed by inclusion of keratinizing squamous epithelium within the dermis, resulting in a cyst filled with lamellated keratin. These benign cysts are usually very small and intradermal subcutaneous lesions. They can occur anywhere in the body although they are more common on the face, trunk, neck, extremities and scalp. Only a few cases of epidermal cysts of the br...
