Invasive lobular carcinoma (ILC) is a distinct type of breast carcinoma and represents 5-15% of invasive breast carcinomas in female. However, the occurrence of ILC is exceptional in male breast, and the incidence is 1.5-1.9% of male breast carcinomas. Herein, we report a case of pleomorphic lobular carcinoma in a male breast. A 76-year-old Japanese male with a history of treatment with a proge...

Atypical lobular hyperplasia (ALH) and lobular carcinoma in situ (LCIS) represent a spectrum of breast disease referred to as "lobular neoplasia" (LN). Although LN occurs relatively infrequently, it is associated with an increased risk of breast cancer, ranging from a three- to four-fold increased risk with ALH up to an eight- to ten-fold increased risk with LCIS. Initially regarded as a direct...

The relationship between ductal and lobular breast carcinoma is highlighted in cases in which these morphologically divergent carcinomas coexist in proximity within a single patient. We hypothesized that such cases may result from the proliferation of a precursor lesion into a tumor containing areas of divergent morphologic features. In this study, we analyzed loss of heterozygosity (LOH) in 10...

Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass...

Invasive lobular carcinoma (ILC) of the breast exhibits unusual clinicopathological, radiological, histological, and metastatic patterns. We present here two cases of ILC of the breast that presented with an unusual pattern of metastasis involving the uterus. Our first patient presented to her primary gynaecologist with profuse vaginal bleeding and underwent total abdominal hysterectomy and bil...

in females, the most common cancer is breast carcinoma in which squamous cell carcinoma (scc) is a rare type of malignancy. histologically, infiltrating ductal carcinoma is the most common type and lobular, mucinous, and medullary types have lower incidence. pure scc of the breast can originate from the skin, nipple, or epithelium of a deep‑seated dermoid cyst or squamous metaplasia on chronic ...

Abstract Background On mammography many cancers may be missed even in retrospect either due to the breast density, small size of tumor or subtle signs cancer that are imperceptible. We aimed compare sensitivity artificial intelligence (AI) digital detection different types cancer. Also, AI picking up morphologies namely mass, pathological calcifications, asymmetry, and distortion was assessed. ...

BACKGROUND Breast-specific gamma imaging (BSGI) is a functional imaging modality that has comparable sensitivity but superior specificity compared with magnetic resonance imaging, yielding fewer false-positive results and thereby improving clinical management of the newly diagnosed breast cancer patient. METHODS A retrospective review was performed from 2 community-based breast imaging center...

to the editor: The article on the risk of cancer in patients with benign breast disease by Hartmann et al. (July 21 issue) 1 contains some questionable assumptions. “Atypical ductal hyperplasia” and “lobular hyperplasia,” shown in Figure 1E and Figure 1F of the article, do not belong in the category of benign breast disease. Experienced pathologists know that the differentiation of the so-calle...
