Distinguishing between reactive mesothelial proliferations and adenocarcinoma is often very difficult. Ancillary studies, in particular immunohistochemistry, are often critical in detecting malignant epithelial cells, especially in serous effusion specimens. MOC-31 and Ber-EP4 are antibodies which target the epithelial cell adhesion molecule (Ep-CAM, TACSTD1) expressed in epithelial cells, and ...
BACKGROUND Prior studies indicate that women with menopausal symptoms have lower estrogen levels because they go through menopause as compared with women who do not experience them. Given the central role of hormones in the etiology of breast cancer, a link between menopausal symptoms and breast cancer is plausible. However, no prior studies have evaluated the association between menopausal sym...
Objectives: Pleomorphic lobular carcinoma (PL) is an aggressive subtype of invasive lobular carcinoma. There are few case series reporting on this aggressive form of breast cancer. This report features a descriptive and survivorship comparison of a large case series of PL reviewed by a single breast pathologist. Methods: From 1993-2010 we retrospectively reviewed 198 cases of invasive lobular c...
The importance of pain as a presenting symptom of breast cancer has been assessed in a series of 240 patients with operable breast cancer over four years. From an analysis of the case histories of 36 patients the diagnosis proved difficult in one-quarter of the cancers. This is explained by the high incidence of subclinical and lobular carcinoma in the group. Cancer must be seriously considered...
PURPOSE Radial scar and radial sclerosis (RS) are considered benign breast lesions with proliferative features. There is sparse literature on frequency of cancer upgrade in these patients without atypical features found on image-guided needle biopsy. This study retrospectively reviews cases of isolated RS diagnosed on needle biopsy and evaluates the cancer upgrade after subsequent surgical exci...
BACKGROUND Breast cancer is a heterogeneous disease with subtypes that may vary in their etiologies. Menopausal hormone therapy has been associated more strongly with lobular and tubular than ductal histologic types and with tumors that are smaller, hormone receptor-positive, and of lower grade. At the same time, correlations have been observed between histology and clinical characteristics. To...
Lobular carcinoma in situ (LCIS) of the breast may exhibit a spectrum of morphologic growth patterns and may also colonize underl ying benign breast lesions. This diversity in appearance can create diagnostic challenges, especially in core needle biopsy specimens. Some LCIS variants may mimic ductal carcinoma in situ or invas ive carcinoma. Furthermore, some LCIS variants are frequently associa...
Breast cancer metastases to the stomach are very rare. As characteristics of breast cancer metastases to the stomach, metastases of lobular carcinoma, mainly with signet ring cells, are frequently observed, and they are often difficult to distinguish from a primary gastric cancer with signet ring cells. Moreover, because no characteristic symptoms are shown and they involve a submucosal lesion,...
BACKGROUND Breast cancer is currently the most common type of cancer in Japanese females. Unlike most other types of cancer, breast cancer develops more frequently in middle-aged females than in elderly females. METHODS Of all Japanese female breast cancer patients aged ≥20 years whom the BioBank Japan Project originally enrolled between 2003 and 2008, 2034 were registered within 90 days afte...
