The vast majority of invasive breast tumors are ductal and lobular breast carcinomas. Despite the many similarities, some clinical follow-up data and the patterns of metastases suggest that these histological subtypes of breast cancer are biologically distinct. Few papers, however, describe immunohistochemical markers useful for differentiation of these carcinomas. Many investigations suggest t...

Background. Breast carcinoma is the most common malignancy in women worldwide. It is most commonly associated with metastases to the liver, lung, bone, and the brain. Invasive lobular carcinoma is a less common pathology with slightly higher metastases to the upper gastrointestinal tract. Invasive lobular carcinoma metastasis to the gallbladder is extremely rare. Method. In this paper we are pr...

Cytomorphologic patterns of breast carcinoma in effusion include three-dimensional groups of tightly packed clusters for invasive ductal type and single files with cytoplasmic signet ring-like cells for invasive lobular type. A mesothelial-like cell pattern has been described for metastatic lobular carcinoma in pleural fluid. We report a case of a patient with a remote history of lobular carcin...

Histiocytoid breast carcinoma is an uncommon entity that is mostly regarded as a variant of lobular carcinoma. Its occurrence with apocrine lobular carcinoma in situ and consistent expression of gross cystic disease fluid protein 15 suggest apocrine differentiation. Its recognition is often challenging, particularly when histiocytoid tumour cells occur in a metastatic site before the primary di...

Numerous studies have evaluated the association between factors related to maturation and reproduction and breast cancer risk, but few have assessed how these factors are related to different histologic types of breast cancer among postmenopausal women. We used polytomous logistic regression to assess the effect of age at maximum height and reproductive factors on risk of invasive breast cancer...

Mammary hamartomas are uncommon breast lesions, sometimes presenting as mammographic abnormalities which require pathological clarification. Previous cases have all been benign. A unique case of mammary hamartoma containing atypical lobular hyperplasia (ALH), lobular carcinoma in situ (LCIS), and foci of microinvasive lobular carcinoma is presented. The need for adequately sampling macroscopica...

Synchronous bilateral male breast cancer is a very rare entity and invasive lobular carcinoma is less common in male breast cancer (MBC) than in female breast cancer (FBC). A 51-year-old man presented with a palpable mass in the left breast was finally diagnosed synchronous bilateral MBC, one an invasive lobular carcinoma and the other an invasive ductal carcinoma. It remains a matter of debate...

INTRODUCTION Invasive ductal and lobular carcinomas represent 67.9% and 6.3% of breast carcinoma, respectively. Metastatic breast cancer typically involves the lungs, bones, brain, and liver. Studies have shown differing patterns of metastatic spread between ductal and lobular carcinoma. Lobular carcinoma is more likely to metastasise to the gastrointestinal tract. CASE PRESENTATION We report...

Lymphovascular invasion (LVI) of breast cancer is an independent adverse prognosticator that is associated with increased regional and distant tumor recurrence. LVI is infrequently encountered in invasive lobular carcinoma when compared to invasive ductal carcinoma. We employed D2-40 antibody, a novel marker for lymphatic endothelial cells, in an attempt to enhance the detection of LVI in invas...

Invasive lobular carcinomas are the second most common type (5% to 15%) of invasive breast carcinomas. The most frequent sites of breast cancer metastasis are the local and distant lymph nodes, brain, lung, liver, and bones; metastasis to the gastrointestinal system, especially to the stomach, is rare. When a mass is detected in an unusual place in a patient with invasive lobular carcinoma, it ...
