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...

Jumonji Domain Containing 2A (JMJD2A) may be a cancer-associated gene involved in human breast cancer. With a view to investigating expression of JMJD2A in human breast cancer and benign lesion tissues as well as relationship between JMJD2A and tumor related proteins, histological and immunohistochemical analysis, Western blot and quantitative real-time PCR in infiltrating duct carcinoma and fi...

Risk factors for fibroadenoma were investigated in a cohort of 265,402 female textile workers in Shanghai, China, who were interviewed at enrollment into a randomized trial of breast self-examination between October 1989 and October 1991 and followed until July 2000. Based on 1,507 women who developed fibroadenoma, relative risks and trends in risk were estimated using Cox regression. The risk ...

A 10 years prepubertal age girl presented duration. Based on the cytological, imaging proliferative breast lesion closest to giant fibroadenoma was offered. in young girls and are difficult to differentiate from low grade phylloides tumor by cytology/ Giant fibroadenomas have to be differentiated from phylloides tumor by the lack of leaf structures and stromal cell atypia and from the breast ha...

CONTEXT AND OBJECTIVE Dendritic cell maturation is considered essential for starting an immune response. The CD83 antigen is an important marker of dendritic cell maturation. The objectives here were to analyze CD83 antigen expression in human breast fibroadenoma and breast tissue adjacent to the lesion and to identify clinical factors that might influence this expression. DESIGN AND SETTING ...

– INTRODUCTION: Cystosarcoma phyllodes are very rare tumors and may be difficult to diagnose clinically. BACKGROUND: Fibroadenomas have long been considered benign hyperplastic lesions rather than true neoplastic processes. However, previous clonality studies have shown differing results. AIM: to assess diagnostic and treatment options for phyllodes tumor. MATERIALS AND METHODS: A 41-year-old f...

OBJECTIVE To analyze the cytologic findings of sclerosing adenosis of the breast. STUDY DESIGN We reviewed the fine needle aspiration (FNA) cytologic slides of 7 cases of sclerosing adenosis of the breast and compared the cytologic findings with those of 10 cases of fibroadenoma and 7 cases of fibrocystic change. RESULTS The smears of sclerosing adenosis were moderately to markedly cellular...

Mammary sclerosing lobular hyperplasia (SLH) is a rare, benign, fibroproliferative tumour-like lesion of adolescent and young women often of African-American heritage. Fine-needle aspiration cytology of mammary SLH shows characteristic features that include an absence of stromal fragments. We report a 45-year-old woman who presented with a gradually enlarging, painless, mobile 4-cm tumour in he...
