AIMS The mutual relation of lobular carcinoma in situ (LCIS) and ductal carcinoma in situ (DCIS) of the breast, as accepted precursor lesions of invasive breast cancer, is controversial. Because they display genetic heterogeneity, it is not clear how genetically advanced these entities are and what causes the transition to an invasive carcinoma. METHODS Six cases of LCIS, four of them with as...

INTRODUCTION To the best of our knowledge, this is the first case report of a multifocal (trifocal) invasive carcinoma of the breast containing osteoclast-like giant cells. CASE PRESENTATION A 64-year-old Caucasian woman presented for routine mammography screening with three radiodense lesions in the lower inner quadrant of the right breast, a primary breast cancer. Microscopic examination sh...

We have examined ten human subjects with a previously developed instrument for near-infrared diffuse spectral imaging of the female breast. The instrument is based on a tandem, planar scan of two collinear optical fibers (one for illumination and one for collection) to image a gently compressed breast in a transmission geometry. The optical data collection features a spatial sampling of 25 poin...

Breast cancer tissues have been analyzed to determine the feasibility of the chemical changes taking place in the biological tissue, which can be identified and categorized into various grades. FTIR spectroscopy can be used for qualitative analysis of cancerous breast tissues because of its sensitivity to the changes in the biomolecules in the tissues. IR spectra was taken for a total number of...

The nipple-areolar complex (NAC) is a specific anatomical and histological structure. Normal structure variabilities, pathological processes various the complexity of diagnostic imaging cause difficulties for radiologists physicians. Breast magnetic resonance (MRI) highly sensitive method structural features, cancer detection NAC. MRI useful as an additional tool when mammography ultrasound fin...

PURPOSE Psoriasin (S100A7) is highly expressed in preinvasive ductal carcinoma in situ of the breast and persistent expression occurs in some invasive carcinomas. This study explores the clinical significance of psoriasin in relation to patient survival in invasive breast cancer. EXPERIMENTAL DESIGN We examined psoriasin expression by immunohistochemistry in a cohort of 122 estrogen receptor-...

Alterations in the gene expression profile in epithelial cells during breast ductal carcinoma (DC) progression have been shown to occur mainly between pure ductal carcinoma in situ (DCIS) to the in situ component of a lesion with coexisting invasive ductal carcinoma (DCIS-IDC) implying that the molecular program for invasion is already established in the preinvasive lesion. For assessing early ...

Incidence rates of ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS) have increased rapidly over the past several decades largely due to the increased use of mammography. However, recent data from 1987 to 1999 indicate that invasive ductal carcinoma incidence rates have remained essentially constant, whereas rates of invasive lobular carcinoma have increased 65%, with greater...

A 44-year-old woman presented with marked erythema over right mastectomy scar, while on Herceptin therapy. She had neoadjuvant chemotherapy, modified radical mastectomy, and radiotherapy less than one year earlier for the treatment of invasive ductal carcinoma. On physical examination, no palpable masses were detected in the erythematous skin. A biopsy revealed permeation of the skin lymphatics...
