A 50 year old woman with a history of infiltrating lobular breast carcinoma presented with back pain. Bone scan and magnetic resonance imaging were not conclusive. A bone marrow aspirate appeared normal. A routine trephine biopsy specimen showed granulomas but no obvious infiltration by carcinoma. Immunohistochemical staining with epithelial markers demonstrated carcinoma cells in the trephine ...

Breast cancer is the second commonest primary tumour responsible for gastrointestinal metastases after malignant melanoma. The real incidence of gastrointestinal metastases in breast cancer patients is probably underestimated owing to the non-specific presenting symptoms and death of patients caused by other more obvious metastases. The predominant histological subtype of gastrointestinal metas...

We report the first proteomic analysis of matched normal ductal/lobular units and ductal carcinoma in situ (DCIS) of the human breast. An understanding of the transition from normal epithelium to the first definable stage of cancer at the functional level of protein expression is hypothesized to contribute to improved detection, prevention, and treatment. Ten sets of two-dimensional gels were e...

Squamous cell carcinoma (SCC) of the breast is very rare entity and when encountered it is found in association with invasive ductal carcinoma of the breast. We report a very unusual association of an invasive lobular carcinoma with metaplastic squamous cell carcinoma of the breast which was found not only in a mastectomy specimen but also in the axillary lymph nodes. The patient reported first...

In a previous study, we found a positive association between premenopausal use of progestagens and breast cancer risk. We conducted the present study to assess the risk of breast cancers defined by their histology and hormone receptors status. We evaluated the association between progestagen-only intake (except for mini pills) before menopause and after the age of 40 years and invasive breast c...

PURPOSE The aim of this study was to describe the imaging features of patients with invasive ductolobular carcinoma of the breast in comparison with the proportion of the lobular component. MATERIALS AND METHODS We retrospectively reviewed mammographic, sonographic and MRI records of 113 patients with proven ductolobular carcinoma diagnosed between January 2008 and October 2012 according to t...

BACKGROUND To date, the clinical presentation and prognosis of mixed ductal/lobular mammary carcinomas has not been well studied, and little is known about the outcome of this entity. Thus, best management practices remain undetermined due to a dearth of knowledge on this topic. METHODS In this paper, we present a clinicopathologic analysis of patients at our institution with this entity and ...

Invasive lobular breast cancer (ILC) accounts for 10-15% of all invasive breast carcinomas. It is generally ER positive (ER+) and often associated with lobular carcinoma in situ (LCIS). Genome-wide association studies have identified more than 70 common polymorphisms that predispose to breast cancer, but these studies included predominantly ductal (IDC) carcinomas. To identify novel common poly...

breast cancer is the most common cancer in women except skin cancer. the common metastatic sites include lymph node, lung, liver and bone. however, metastasis to the bladder is extremely rare. to our knowledge, this is the first case of breast cancer metastasis to urinary bladder in jordan which is reported. nine years after the initial diagnosis of lobular breast carcinoma, the patient suffere...

The expression of basal cytokeratin markers CK5/6 in breast carcinomas has been associated with high histological grade and poor clinical outcome. A previous study has shown that CK5/6 can be detected in up to 17% of invasive lobular carcinomas (ILC). Here we study the expression of three basal cytokeratin markers (CK5/6, CK14, and CK17) in 53 ILC cases diagnosed by histology and lack of E-cadh...
