BACKGROUND Occurrence of gastric metastasis as the first symptom of breast carcinoma with a long period of latency before presentation of the primary breast carcinoma is rare. CASE REPORT A patient with gastric metastasis as the first symptom of lobular breast carcinoma, treated by neoadjuvant preoperative chemoradiotherapy and total gastrectomy, with complete local control. Fourteen months a...

Combined estrogen and progestin hormone therapy (CHT) increases breast cancer risk, but this risk varies by breast cancer type. Several studies indicate that CHT is more strongly related to lobular carcinoma risk than to ductal carcinoma risk, but these studies have been limited in their assessments of recency and duration of use, and none included a centralized pathology review. We conducted a...

Management of cancer patients in low-resource communities presents enormous challenges. Breast cancer is a public health problem in Cameroon and occurs mostly in elderly women. The predominant histological type is a duct carcinoma. Lobular carcinoma in teenagers is rare. In this report we present a case of bilateral invasive lobular carcinoma of the breast that was confirmed on biopsies in a 22...

We report two cases of invasive lobular carcinoma of the breast that were initially missed on first mammographic interpretation because of an uncommon, easily overlooked, and unreported imaging presentation. The abnormality in the cases manifested as an apparent decrease in breast glandular tissue volume when compared with the patients' previous mammograms, observed as "shrinking" of the breast...

Immunohistochemistry using antibodies to cytokeratin 8 can serve as a valuable diagnostic tool for the differentiation of lobular from ductal carcinomas of the breast. In contrast with ductal carcinomas, which exhibit a peripheral-predominant immunostaining pattern, adjacent tumor cells “molding” to each other, lobular carcinomas exhibit a ring-like perinuclear immunostaining pattern, creating ...

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...

Histiocytoid breast carcinoma (HBC) is a rare type of breast cancer with a controversial histogenesis. Here we describe a case report of a 65-year old woman with HBC. The patient presented with two masses in the right breast. Histopathologically, the tumors consisted of a diffuse infiltration of large tumor cells and histological components of carcinoma in situ and atypical lobular hyperplasia ...

High-risk lesions of the breast are lesions that confer an increased risk of breast cancer, either because of an increased probability of finding cancer associated with percutaneous biopsy findings or because of an increased probability of developing breast cancer over the long term. Atypical ductal hyperplasia found on percutaneous biopsy is generally excised, whereas lobular neoplasia lesions...

BACKGROUND Male breast cancer is rare and represents less than 1% of all breast cancers. Considering the fact that the male breast most often does not consist of lobules and acini, lobular carcinoma of the male breast is exceptionally rare. CASE REPORT In this paper we present a unique case of alveolar variant of lobular male breast cancer in a 56-year-old patient. CONCLUSION According to o...

Gastrointestinal (GI) metastases from primary breast carcinoma are rare but more common in invasive lobular carcinoma than invasive ductal carcinoma. The symptoms may be non-specific and the presentation can occur many years after the initial primary breast carcinoma. Radiological and endoscopic findings can be difficult to distinguish from inflammatory bowel disease and primary carcinoma of th...
