background and objective: breast cancer is the commonest cancer of indian women. estrogen and progesterone expression is seen in benign breast lesions and in breast carcinoma associated with good prognostic parameters and it correlates well with response to hormone therapy. although a lot of studies have been conducted in the past on hormone receptor expression in breast cancer and few have cor...

background: phyllodes tumor (pt) of the breast in hispanic patients is more frequently reported with large tumors and with more borderline/malignant subtypes compared with other populations. the objective of this study was to describe characteristics of patients with pt and to identify differences among subtypes in a mexican population.  methods: a retrospective study was conducted on patients ...

Malignant transformation of glomus tumor is exceedingly rare and most common reported in lower extremity and abdominal viscera. We could find only 6 previous case report of malignant glomus tumor in the hand. Although large and deeply located glomus tumors are considered to be malignant, evidence has shown that most of these cases were clinically benign. These lesions are better considered as g...

BACKGROUND Breast cancer has a strong genetic component, and at least two breast cancer genes exist. But these genes probably play little role in most breast cancers. Other factors, such as environmental estrogens and diet, may cause the genetic changes involved in the genesis of sporadic breast cancer. A method of observing genetic changes indirectly might be to measure tumor markers known to ...

Abstract Background Phyllodes tumors of breast are rare fibroepithelial neoplasms. They have similar radiological findings with fibroadenomas. While fibroadenomas benign lesions, phyllodes may malignant potential. Therefore, any imaging to differentiate fibroadenoma from tumor valuable. Case presentation A 51-year-old female patient was admitted our clinic the complaint a palpable mass. Tru-Cut...

PURPOSE Insulin-like growth factors (IGFs) are potent mitogens for breast cancer cells in vitro, and elevated IGF-I serum levels are a risk factor for breast malignancies. This study evaluated IGF-I and IGF-II serum levels in healthy women and in patients with benign and malignant breast lesions and correlated them with tumor size. EXPERIMENTAL DESIGN Serum levels of the total and unbound fra...

ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....

Cytomegalovirus (CMV) is a widespread pathogen that is found in milk, saliva, urine, cervical secretions, and semen fluid. It is supposed that CMV is a risk factor for breast cancer. The aim of this study was to determine the frequency of CMV among benign and malignant breast tumors. Paraffin embedded breast carcinoma (n=24) and fibroadenoma (n=24) samples were collected from Toos and Firoozgar...

the distinction between malignant and benign pheochromocytoma has always been a diagnostic challenge over the last decades. to date, the only reliable criterion is metastasis. the aim of the present study was to investigate the possible expression of pituitary-tumor transforming gene (pttg1) and retinoblastoma (rb) in benign and malignant pheochromocytoma. paraffin blocks of 44 and 11 patients ...
