BACKGROUND Using new molecular biology techniques, recent studies have implicated a common evolutionary pathway between lobular neoplasia, lobular carcinomas, and columnar cell lesions. Our aims were to assess the frequency of lobular neoplasia in a series of breast biopsies that were performed and examined in the same institution and to analyze the association between subtypes of lobular neopl...

Purpose: To determine the clinicopathological features and survival outcomes of triple-negative breast cancer (TNBC) according to different histological subtypes. Methods: Using the Surveillance, Epidemiology, and End Results database, we included TNBC cases in 2010-2013. The effect of histological subtype on breast cancer-specific survival (BCSS) and overall survival (OS) were analyzed using u...

Benign epithelial lesions with no significant tendency to malignant transformation include: adenoma: -Ductal -lactating -Tubular adenosis: -apocrine -blunt duct -microglandular -sclerosing fibroadenoma radial scar/complex sclerosing lesions Invasive breast carcinomas are divided into two major categories on the basis of their cytoarchitectural features: Invasive ductal carcinoma: -acinic cell c...

Lobular carcinoma in situ (LCIS) clinically constitutes a risk factor for the subsequent development of either invasive lobular carcinoma (ILC) or invasive ductal carcinoma (IDC). In order to approach the possibility of this common precursor of both ILC and IDC, we investigated combined lobular and ductal carcinomas. Thirty-two cases of lobular carcinoma were picked up out of 773 cases of opera...

ba c k g r o u nd: skin  metastases occur  in  1-5%  of  solid  tumors  and  are  rarely the presenting sign of internal malignancies. certain features in skin lesions raise suspicion of metastasis from solid tumors. c a s e presentation: in this article a 61-year-old woman is presented with erythematous skin nodules  in  upper  abdomen  and  chest. histopathological evaluation  of  lesions sug...

Invasive lobular carcinoma of the breast has similar patterns of metastatic disease when compared to invasive ductal carcinoma; however, lobular carcinoma metastasizes to unusual sites more frequently. We present a 65-year-old female with a history of invasive lobular breast carcinoma (T3N3M0) treated with modified radical mastectomy and aromatase-inhibitor therapy who underwent a surveillance ...

Carcinoma of male breast is uncommon as it accounts for 0.7% of total breast cancer. The pathology of male breast cancer is remarkably similar to that of cancers seen in women. The same histological subtypes of invasive cancer are present, although papillary carcinomas (both invasive and in situ) are more common and lobular carcinomas are less common. The predominant histological type, in males...

Pleomorphic variant of lobular carcinoma is a recently described variant of invasive lobular carcinoma. It is reported to be positive for estrogen receptors and progesterone receptors and over express Her2/neu in most cases. We present here a case of invasive variant of pleomorphic lobular carcinoma with coexisting classic and pleomorphic variants of lobular carcinoma in situ along with focal d...

The differences between invasive lobular and ductal carcinomas affect the diagnostic and therapeutic management for patients with breast cancer. In most cases, this can be accomplished because of distinct histomorphologic features. However, occasionally, this task may become quite difficult, in particular when dealing with the variants of infiltrating lobular carcinoma. Lobular carcinoma has be...

BACKGROUND Lobular carcinoma in accessory breast tissue is a rare occurrence. We present such a case in a 61-year-old woman. CASE PRESENTATION A skin nodule in the axillary skin on excision biopsy revealed invasive lobular carcinoma. CONCLUSIONS Carcinoma in accessory breast tissue is uncommon especially invasive lobular type. A high index of suspicion may avoid late diagnosis.
