Pure ductal invasive carcinoma of the breast is more frequently associated with lymphatic invasion, lymph node involvement and high malignant histological grade than combined forms of breast carcinoma. Internal mammary node metastases are not frequently detected when the axillary nodes are negative.
We report our experience of a case of pure cribriform carcinoma, associated with an intraductal cribriform component, in which the sentinel axillary nodes were negative, while nodal and perinodal metastasis was detected in one internal mammary lymph node.
Data from the literature show that positive internal mammary nodes are an unusual finding when the axillary sentinel node is negative, especially in cases of cancer with a relatively good prognosis, such as cribriform cases.

    ABSTRACT: There is increased understanding of the heterogeneity of breast tumors, with greater emphasis now being placed on histological and molecular profiles and, in particular, their implications for prognosis and therapy. This review addresses breast cancers of unusual histological subtype with an approximate incidence ≤1%. Given the rarity of these tumors, the literature contains primarily case reports, small series, and population-based studies. Data are heterogeneous and almost entirely retrospective, frequently gathered over long time periods, in the context of changing pathological techniques and reporting. In addition, our understanding of the disease biology and therapeutic context has also evolved significantly over this time. There is often limited information about the specific therapies used and the rationale for choosing such an approach. Meaningful comparisons of treatment modalities are not feasible and it is not possible to define management guidelines. Instead, this review correlates the available information to give an impression of how each subgroup behaves-of the favored surgical technique, responses to therapy, and prognosis-as well as the emerging molecular data, highlighting new research areas for potential target in clinical trials. Each tumor subtype described represents a small but real cohort of patients with breast cancer, and although inferences may be made from this review, we are mindful of the paucity of data. The management of each patient must be considered in the context of their unique clinical presentation and correlated with the evidence-based principles that apply to more common breast cancer histologies.

    ABSTRACT: Because of the vast heterogeneity of in situ breast lesions, the morphologic diagnosis of ductal carcinoma in situ (DCIS) is challenging. The objective of this article is to present a "pictorial journey" through the infrequently encountered variants of DCIS and benign and malignant DCIS mimickers to familiarize readers with these rare entities, since these lesions can be a source of infrequent diagnostic pitfalls. Recognition of these unusual variants is crucial for proper patient management. Unusual variants of DCIS and DCIS mimickers are presented in this article. Examples of DCIS with a high propensity for underdiagnosis or misclassification, pertinent immunoperoxidase workups, the results of prognostic/predictive markers, and relevant clinical follow-up are also provided in certain cases. The currently controversial entities are also discussed.

    ABSTRACT: Invasive cribriform carcinoma (ICC) and low-grade invasive ductal carcinoma (IDC) were recently considered to belong to a low-grade breast neoplasia family. However, none of publications has compared ICC and low-grade IDC at present. Meanwhile, in order to evaluate prognostic significance of clinicopathological characteristics of different cribriform contents in ICC and invasive breast cancer with less cribriform structures, a retrospective review of fifty-one cases of ICC and forty cases of invasive breast cancer with less cribriform pattern (less than fifty percent) was conducted in a Chinese population. Forty-nine cases of low-grade IDC without cribriform elements were selected as a control. ICC presented more favorable prognostic factors than those of invasive breast carcinoma with less cribriform pattern and low-grade IDC, such as smaller tumor size, less frequent axillary lymph node involvement, higher positive rate of estrogen receptor and/or progestogen receptor expression, and lower proliferation index. The expression of human epidermal growth factor receptor two in ICC and invasive breast cancer with less cribriform pattern was mostly negative. Pure ICC showed less frequency of axillary lymph node involvement, but not its number. The proliferation index in the pure type was lower, although the tumor size in these two types was not obviously different. Tumors contained cribriform structures had a more favorable prognosis than those with low-grade IDC. Considering the tumor biology, and the benign course of pure ICC studied, chemotherapy may not be indicated in the typical case.
