Pleomorphic Lobular Carcinoma

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, as in females, reported in large series has been infiltrating ductal carcinoma with scattered reports of infiltrating lobular carcinoma, all of them of classical type except for a single case of pleomorphic infiltrating lobular carcinoma. Herein, we describe a case of pleomorphic lobular carcinoma occurring in male breast.

177 Background: Pleomorphic lobular carcinoma in situ (PLCIS) is an increasingly diagnosed variant of lobular carcinoma in situ. Histologically, it resembles ductal carcinoma in situ (DCIS), leading to controversy over proper management. Yet, the natural history of PLCIS is unknown. Here we describe our experience with PLCIS. Methods: Review of pathology reports (1995–2012) identified 233 cases of LCIS variants. Patients with synchronous ipsilateral DCIS or invasive cancer (IC) were excluded leaving 25 cases for review. Consensus review by 3 pathologists further excluded 7; leaving 18 cases, 12 of which were classified as PLCIS and 6 as LCIS with pleomorphic features (LCIS-PF). (Table) PLCIS was defined by cellular dyshesion, nuclear pleomorphism with a 2-3 fold size variation, conspicuous nucleoli, mitoses and abundant cytoplasm; lesions not meeting all parameters were classified as LCIS-PF. Loss of e-cadherin was confirmed; clinical data were obtained from medical records. Results: Mean patient age at diagnosis of PLCIS/LCIS-PF was 57 yrs (42-67 yrs). All cases presented with imaging abnormalities. A previous history of breast cancer was present in 7/18 (39%) pts (3/7, ipsilateral; 4/7, contralateral). Following PLCIS/LCIS-PF diagnosis, 6/18 (33%) pts underwent mastectomy and 12/18 had excision alone, with (n=3) or without chemoprevention (n=9). Margin status was negative in 4/12 pts; close in 3/12 pts and positive in 5/12 pts undergoing excision. At a median follow-up of 27 mos (2-148 mos), 2/12 pts treated with excision developed ipsilateral breast cancer (1 DCIS; 1 IC). Both had close margins at initial excision; median time to cancer, 54 mos. Conclusions: Pure PLCIS is an uncommon lesion. Synchronous malignancy or prior history of breast cancer are often present in patients with PLCIS, contributing to the difficulty in determining the actual risk conferred by this lesion and appropriate management. Efforts to systematically characterize LCIS variants and prospective documentation of outcomes are needed to clarify the significance of these lesions. [Table: see text]

This study aimed to evaluate the role of Ag NORs in improves diagnosis of Breast cancer with different subtypes’ among Sudanese Patients. This study include tissue sections of breast cancer diagnosed women, they were 30, ductal and lobular invasive carcinoma were 10 for each, while ductal and lobular in-situ carcinoma were 5 each. Found correlation between subtypes of breast cancer and Ag NOR , Invasive ductal carcinoma had more NOR while the lobular carcinoma in situ was less one , Stage III most frequency than the other stage. Silver staining were performed and Ag-NOR were detected in ductal and lobular invasive carcinoma more than ductal and lobular in-situ carcinoma, grade III has more frequency of Ag-NOR than other stages, and no correlation found between Ag-NOR and age group

Pleomorphic Lobular Carcinoma

Abstract Context.—Lobular neoplasias (LNs) of the breast include atypical lobular neoplasia and lobular carcinoma in situ. Recent evidence suggests that LN is not only a risk factor for invasive lobular carcinoma, but is also a nonobligate precursor. Pleomorphic lobular carcinoma in situ (PLCIS) is a subtype of LN that has high-grade nuclei and other features that may mimic high-grade ductal carcinoma in situ. The management and follow-up of patients diagnosed with LN on core biopsy is a current issue of debate. However, recent genomic and molecular studies have identified candidate genes that may be important in understanding the pathogenesis of atypical lobular neoplasia and lobular carcinoma in situ, and thus may lead to other therapeutic interventions. Objective.—To review the literature on LN of the breast and discuss current issues in the diagnosis and management of this entity, with particular attention to the relatively newly recognized lesion PLCIS. Because the management of PLCIS varies from the other LN lesions, the recognition of PLCIS by the pathologist is necessary. Current issues in the molecular pathogenesis of LN are also presented. Data Sources.—Extensive review of the literature. Hematoxylin-eosin–stained and immunohistochemical-stained tissue from the author's personal collection. Conclusions.—Although morphology and immunohistochemical stains, such as E-cadherin, are important in the diagnosis and understanding of LN, genomic and molecular studies may guide the way these lesions are handled in the future. Recognizing PLCIS is important both for patient management and for our future understanding of LN pathogenesis.

<b><i>Purpose:</i></b> Classical type of lobular neoplasia (LN) encompassing both atypical lobular hyperplasia and classical lobular carcinoma in situ of the breast is a lesion with uncertain malignant potential and has been the topic of several studies with conflicting outcome results. The aim of our study was to clarify outcome-relevant factors and treatment options of classical LN. <b><i>Methods:</i></b> We performed a pathological re-evaluation of the preoperative biopsy specimens and a retrospective clinical and radiological data analysis of 160 patients with LN from the Breast Center Zurich. Open surgery was performed in 65 patients, vacuum-assisted biopsy (VAB) in 79 patients, and surveillance after breast core needle biopsy (CNB) in 16 patients. <b><i>Results:</i></b> The upgrade rate into ductal carcinoma in situ/invasive cancer was the highest in case of imaging/histology discordance (40%). If the number of foci in the biopsy specimen was ≥3, the upgrade rate in the consecutive surgical specimens was increased (<i>p</i> = 0.01). The association of classical LN with histological microcalcification correlated with shortened disease-free survival (<i>p</i> &#x3c; 0.01), whereas other factors showed no impact on follow-up. <b><i>Conclusions:</i></b> Surveillance or subsequent VAB after CNB of LN is sufficient in most cases. Careful consideration of individual radiological and histological factors is required to identify patients with a high risk of upgrade into malignancy. In those cases, surgical excision is indicated.

Purpose Although breast-conserving surgery is a standard approach for patients with breast cancer, mastectomy often becomes necessary. Surgical options now include nipple-sparing mastectomy but its oncological safety is still controversial. This study evaluates frequency and patterns of occult nipple involvement in a large contemporary cohort of patients with the retroareolar margin as possible indicator of nipple involvement. Patients and Methods Three hundred sixteen consecutive mastectomy specimens (232 therapeutic, 84 prophylactic) with grossly unremarkable nipples were evaluated by coronal sections through the entire nipple and subareolar tissue. Extent and location of nipple involvement by carcinoma was assessed with the tissue deep to the skin as potential retroareolar en-face resection margin. Results Seventy-one percent of nipples from therapeutic mastectomies showed no pathologic abnormality, 21% had ductal carcinoma in situ (DCIS), invasive carcinoma (IC), or lymphovascular invasion (LVI), and 8% lobular neoplasia (lobular carcinoma in situ). Human epidermal growth factor receptor 2 amplification, tumor size, and tumor-nipple distance were associated with nipple involvement by multivariate analysis (P = .0047, .0126, and .0176); histologic grade of both DCIS (P = .002) and IC (P = .03), LVI (P = .03), and lymph node involvement (P = .02) by univariate analysis. Nipple involvement by IC or DCIS was identified in the retroareolar margin with a sensitivity of 0.8 and a negative predictive value of 0.96. None of the 84 prophylactic mastectomies showed nipple involvement by IC or DCIS. Conclusion Nipple-sparing mastectomy may be suitable for selected cases of breast carcinoma with low probability of nipple involvement by carcinoma and prophylactic procedures. A retroareolar en-face margin may be used to test for occult involvement in patients undergoing nipple-sparing mastectomy.
