Introduction Not only is breast carcinoma the second leading cause of cancer mortality, it is also the most common form of cancer in women. Accumulation of genetic alterations within a single clone of cells eventually leads to uncontrolled growth. Models of progression of breast carcinoma suggest that the epithelial cell gives rise to carcinoma in situ after first going through phases of hyperp...

We evaluated the efficacy of using standard radiologic and histologic criteria to guide the follow-up of patients with lobular carcinoma in situ (LCIS), lobular neoplasia (LN), or atypical lobular hyperplasia (ALH). Patients with high-risk benign lesions diagnosed on biopsy were presented and reviewed in a multidisciplinary clinical management conference from 1 November 2003 through September 2...

Infiltrating lobular carcinoma (ILC) and infiltrating ductal carcinoma (IDC) are distinguished by their histopathological appearance. However, little is known about the differences in genetic changes between lobular cancers and ductal cancers. We used comparative genomic hybridization (CGH) and compared aberrations in 19 ILCs and 46 IDCs. The total number of aberrations was lower in ILC than in...

Gastrointestinal metastases from invasive lobular breast cancer are uncommon with the stomach and small intestines being the most common metastatic sites. Peritoneal and rectal metastases are very rare and only rarely occur as the first manifestation of disease. We herein report the case of a 47-year-old woman who presented with abdominal carcinomatosis as a first sign of invasive lobular breas...

A sinister and stealthy marauder, infiltrating lobular carcinoma (ILC) can potentially elude detection due to its pathologic appearance. As reviewed in the last issue of The WCC Note, the shape of ILC at pathology varies. It ranges from tumors with irregular margins; to those displaying diffuse invasion with cells infiltrating single file or loosely associated; to variants with large groups of ...

This study aimed to ascertain pathologic findings of surgical follow-up excision (FUE) on patients who had radiologic finding of calcifications and lobular neoplasia (LN) on core biopsy. Breast core biopsy specimens from 2006-2011 with a diagnosis of pure classic-type LN (lobular carcinoma in situ [LCIS] and atypical lobular hyperplasia [ALH]) with no history of invasive carcinoma (IC) or ducta...

Forty-eight patients with breast carcinoma were subjected to four quadrant fine needle aspiration (FNA) cytology examination of the ipsilateral and contralateral breast in an attempt to detect any accompanying benign proliferative lesion. Mastectomy of ipsilateral and open biopsy of contralateral breast provided material for histopathological study. Cytological evidence of epithelial proliferat...

An unusual mixed form of ductal carcinoma in situ (DCIS) of the breast is described, which exhibits a biphenotypic morphology encompassing a range of differential diagnostic DCIS subtypes. In addition, immunophenotypic and ultrastructural studies demonstrate neuroendocrine and apocrine differentiation, raising questions regarding appropriate classification and biological behaviour. In two cases...

Breast cancer is usually associated with metastases to lungs, bones and liver. Breast carcinoma metastasizing to the gallbladder is very rare. We report the case of 45-year-old female with clinical presentation of acute Cholecystitis, who underwent cholecystectomy in emergency. The Gallbladder showed a nodule on the Gallbladder wall. Histological examination disclosed a metastasis from a lobula...
