BACKGROUND: The diagnosis and management of lobular neoplasia (LN) including lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) remains controversial. Current management options after a core needle biopsy (CNB) with lobular neoplasia (LN) incorporating both ALH and LCIS include excision biopsy or careful clinical and radiologic follow up. METHODS: A retrospective analysis of the surgical database at Cork University Hospital was performed to identify all core needle biopsies from January 1st 2010 to 31st December 2013 with a diagnosis of FA who subsequently underwent surgical excision biopsy...

OBJECTIVES: Bi- and multinucleated (B/M) cells are present in a variety of tumors. We evaluated lobular carcinoma in situ (classic and pleomorphic types) and ductal carcinoma in situ (DCIS) to determine if this objective morphologic feature aids the differential diagnosis. METHODS: The number of B/M cells was recorded in pleomorphic lobular carcinoma in situ (PLCIS) (n = 20), classic lobular carcinoma in situ (CLCIS) (n = 26), and DCIS (n = 37). RESULTS: Binucleated cells were significantly more frequent in PLCIS (100%) vs DCIS (43%; P < ...

BACKGROUND: Pleomorphic lobular carcinoma in situ (PLCIS) is an unusual variant of LCIS for which optimal management remains unclear. METHODS: We conducted a 15-year (2000-2014) retrospective chart review of the radiologic, pathologic, clinical management, and recurrence rates of patients with PLCIS on diagnostic biopsy. Fifty-one patients were found to have PLCIS either alone or with concomitant breast cancer. Of these, 23 were found to have pure PLCIS on diagnostic biopsy...

The retrodural space of Okada is situated dorsal to the ligamentum flavum in the interlaminar space, and provides communication between contralateral facet joints. MRI will often demonstrate heterogeneous signal abnormality with contrast enhancement in this space and several communicating compartments of the posterior ligamentous complex: bilateral facet joints, adventitial interspinous bursae, or retrodural cysts penetrating the ligamentum flavum. Pars interarticularis defects are frequently present. This imaging pattern may be associated with axial low back pain and/or radicular pain...

The clinical significance of pleomorphic lobular carcinoma in situ (PLCIS) is a subject of controversy. As a consequence, there is a risk of providing inconsistent management to patients presenting with PLCIS. This review aims to establish whether the current guidelines for the management of PLCIS are consistent with current evidence. A systematic electronic search was performed to identify all English language articles regarding PLCIS management. The data was analysed, specifically looking at: incidence of concurrent disease, recurrence rates, long-term prognosis and PLCIS management...

OBJECTIVES: To evaluate the underestimation rate and clinical relevance of lobular neoplasia in vacuum-assisted breast biopsy (VABB). METHODS: A total of 161 cases of LN were retrieved from 6,435 VABB. The histological diagnosis was ALH (atypical lobular hyperplasia) in 80 patients, LCIS (lobular carcinoma in situ) in 69 patients and PLCIS (pleomorphic lobular carcinoma in situ) in 12 patients. Seventy-six patients were operated on within 2 years after VABB and 85 were clinically and radiologically monitored...

BACKGROUND: The significance of lobular neoplasia (LN), lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH)) found at core needle biopsy (CNB) of the breast remains uncertain. There is a consistent risk of underestimating malignancy after the diagnosis of LN on CNB. The aim of this study was to determine if patients with a CNB result of LN need surgical excision. METHODS: Patients were identified by searching the institutions pathology database for the terms "lobular carcinoma in situ" and "atypical lobular hyperplasia" over 20 years...

CONTEXT: The appropriate treatment for patients with pleomorphic lobular carcinoma in situ (PLCIS) is unknown. When diagnosed on core biopsy, excision is recommended; however, management of PLCIS when it involves margins has not been addressed. OBJECTIVE: To evaluate the significance of PLCIS that is located close to, or at, a resection margin. DESIGN: We identified 26 patients with resection specimens containing PLCIS, all of whom were offered chemoprevention and radiation therapy...

AIMS: Pleomorphic lobular carcinoma in situ (PLCIS) is an uncommon, recently recognized variant of lobular carcinoma in situ (LCIS). Its natural history, biological behaviour and clinical characteristics are uncertain. The aim was to review the radiological and pathological findings in a series of screen-detected PLCIS diagnosed on needle core biopsy with a view to determining the diagnostic features, immunohistological profile and risk of concurrent invasive malignancy. METHODS AND RESULTS: Ten cases of core biopsy-diagnosed, screen-detected PLCIS were identified...

The clinical, pathologic, and molecular features of pleomorphic lobular carcinoma in situ (PLCIS) and the relationship of PLCIS to classic LCIS (CLCIS) are poorly defined. In this study, we analyzed 31 cases of PLCIS (13 apocrine and 18 nonapocrine subtypes) and compared the clinical, pathologic, immunophenotypic, and genetic characteristics of these cases with those of 24 cases of CLCIS. Biomarker expression was examined using immunostaining for E-cadherin, gross cystic disease fluid protein-15, estrogen, progesterone, androgen receptor, human epidermal growth factor receptor2, CK5/6, and Ki67...

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...

Pleomorphic lobular carcinoma in situ (PLCIS) is a more recently characterized entity that mimics high-grade ductal carcinoma in situ (DCIS). PLCIS is sometimes treated similar to high-grade DCIS, but no consensus has been reached for the most appropriate treatment. The aim of this study is to evaluate the histologic and immunohistologic profile of pure PLCIS on core needle biopsies and present follow-up clinical data. We reviewed 12 cases of pure PLCIS diagnosed on core needle biopsies of the breast along with subsequent surgical resections...

BACKGROUND: Breast ductal lavage (DL) is a noninvasive procedure for sampling ductal epithelial cells. Patients at risk for breast cancer or with prior history can be monitored by DL. This report compares cytomorphology in concurrent DL, fine needle aspiration (FNA) and histology in a case of pleomorphic lobular carcinoma in situ (PLCIS) with signet ring features. CASE: A 57-year-old woman had DL and FNA performed after quadrantectomy for lobular carcinoma in situ with signet ring cell features...

Pleomorphic variant of invasive lobular carcinoma (PILC) is an aggressive variant of invasive lobular carcinoma (ILC). Its in situ counterpart, pleomorphic lobular carcinoma in situ (PLCIS) is a recently described entity. Morphologically it has the typical architectural pattern of LCIS, but the neoplastic cells resemble intermediate grade DCIS. Molecular signatures that distinguish PLCIS from DCIS and LCIS would provide additional tools to aid in the histopathologic classification of PLCIS as a lesion distinct from LCIS and DCIS...

Immunohistochemical analysis of E-cadherin has changed the way lobular neoplasia is perceived. It has helped to classify difficult cases of carcinoma in situ with indeterminate features and led to the identification of new variants of lobular carcinoma. Pleomorphic lobular carcinoma (PLC) and pleomorphic lobular carcinoma in situ (PLCIS), recently described variants of invasive and in situ classic lobular carcinoma, are reported to be associated with more aggressive clinical behaviour. Although PLC/PLCIS show morphological features of classic lobular neoplasia and lack E-cadherin expression, it is still unclear whether these lesions evolve through the same genetic pathway as lobular carcinomas or are high-grade ductal neoplasms that have lost E-cadherin...

We reviewed 10 cases of pleomorphic lobular (ductal lobular) carcinoma in situ (PL/DLCIS) of the breast and compared them with 14 cases of pleomorphic lobular carcinoma in situ (PLCIS) found in association with invasive pleomorphic lobular carcinoma. The histologic features; immunohistochemical staining for estrogen receptors (ERs), p53, Ki67, E-cadherin, and gross cystic disease fluid protein-15 (GCDFP-15); and results of fluorescence in situ hybridization for HER-2/neu gene amplification were evaluated in all 24 cases...

Infiltrating pleomorphic lobular carcinoma (PLC) is an aggressive variant of infiltrating lobular carcinoma. Recently, in situ changes identical to PLC (PLCIS) have been described. The role of prognostic markers and their correlation with therapeutics, clinical outcome, and genetic changes is not well established in PLC. The authors examined 38 cases of this entity to understand better this tumor's biology. Immunohistochemical (IHC) analysis was performed in 21 specimens for estrogen and progesterone steroid receptors, p53, Her 2 (p185), and GCDFP-15...
