KEY CLINICAL MESSAGE The patient developed multiple bone metastases following mastectomy with silicone reconstruction and contralateral augmentation for ductal carcinoma in situ (DCIS) of the breast. She was diagnosed with contralateral invasive cancer. Distant metastasis of DCIS is rare, and other metastatic origins must be screened. However, screening of augmented breasts is difficult.

UNLABELLED The mechanism of progression from ductal carcinoma in situ (DCIS) to invasive ductal carcinoma (IDC) remains largely unknown. We compared gene expression in tumors with simultaneous DCIS and IDC to decipher how diverse proteins participate in the local invasive process.Twenty frozen tumor specimens with concurrent, but separated, DCIS and IDC were microdissected and evaluated. Total ...

Data derived from histopathological analysis, natural history, radiological characteristics, molecular markers, and clinical outcome indicate that ductal carcinoma in situ (DCIS) is a heterogeneous disease, meaning that no one treatment strategy is best, but rather that treatment should be personalised and entail a systematic and rigorous multidisciplinary approach. Many women with DCIS will de...

Collagenase-3 (matrix metalloproteinase 13; MMP-13), a protease originally identified in breast carcinoma, is characterized by a potent degrading activity against a wide spectrum of extracellular matrix proteins. The aims of this study were to localize and identify the MMP-13-expressing cells in invasive human breast carcinoma and to evaluate the role of MMP-13 in transition to invasive lesions...

The identification of breast ductal carcinoma in situ (DCIS) is a factor that increases 8-10 times the risk of developing invasive ductal breast carcinoma (DCI) later. In this study, we evaluated the immunoexpression of the HER2/neu oncoprotein in the DCIS cases associated with DCI, both in situ and in the invasive components. We also studied the Her2/neu immunoreactivity in the cases of DCI ha...

BACKGROUND Diagnosis of ductal carcinoma in situ (DCIS) in breast cancer cases is challenging for pathologist due to a variety of in situ patterns and artefacts, which could be misinterpreted as stromal invasion. Microinvasion is detected by the presence of cytologically malignant cells outside the confines of the basement membrane and myoepithelium. When malignant cells invade the stroma, ther...

Breast ductal carcinoma in situ (DCIS) is a preinvasive form of breast cancer. It typically presents as microcalcifications which are picked up on screening mammogram. We report an atypical case of breast DCIS presenting with recurrent non-puerperal mastitis with a normal mammogram and perform a literature review.

Corresponding to the increased use of mammography, the incidence of ductal carcinoma in situ (DCIS) has risen dramatically in the past 30 years. Despite its growing incidence, the treatment of DCIS remains highly variable and controversial. Although DCIS itself does not metastasize and is never lethal, it may be a precursor of invasive breast cancer and is a marker of increased breast cancer ri...

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...
