Abstract
The nipple can be affected by many malignant and benign entities. A wide variety of diseases including Paget disease, atopic dermatitis and nipple candidiasis can cause eczema-like changes in the nipple. In cases of diagnostic uncertainty, tissue sampling may be indicated. A true eczematous lesion, such as atopic dermatitis, typically shows a spongiotic dermatitis pattern. Paget disease, on the other hand, presents with infiltration of the nipple epidermis by neoplastic cells. The presence of atypical cells scattered in the epidermis in a pagetoid pattern opens up a histopathological differential diagnosis encompassing squamous cell carcinoma in situ and malignant melanoma, among others. Immunohistochemistry is commonly used to render a diagnosis. The objective of this article is to discuss Paget disease and highlight relevant clinical and histopathological differential diagnoses.

Abstract
Because of the unique anatomic structure of the nipple, a few specific breast lesions occur only at this site. Large lactiferous sinuses may be involved by inflammatory conditions such as squamous metaplasia of lactiferous ducts and ductal ectasia or be the site of uncommon superficial epithelial neoplasms such as nipple adenoma or syringomatous tumor of the nipple. Paget disease of the nipple may be secondary to intraepidermal extension of ductal carcinoma in situ in the underlying lactiferous ducts or develop from malignant transformation of Toker cells. Invasive breast cancer may also arise primarily in the nipple. Most of these conditions present as a palpable mass and/or skin changes with or without nipple discharge. Due to the delicate location and often relatively small size of nipple lesions, biopsy specimens are often superficial and fragmented, and the interpretation is challenging. Knowledge of the morphologic and immunophenotypic features of nipple lesions is essential in making the correct diagnosis. Information on the molecular alterations underpinning nipple neoplasms is currently very limited.

Abstract
Paget's disease of the breast typically affects postmenopausal women and is associated with an underlying malignancy. Skin changes are a common presenting symptom, as well as a lump, nipple discharge, pain and changes to the nipple shape. Imaging options include ultrasound for women under the age of 35 years or mammogram and ultrasound for women over the age of 40 years. The definitive diagnostic investigation is a tissue core biopsy. Cases are discussed by a multidisciplinary team to decide on the optimal management strategy. Management options are typically surgical and include breast-conserving surgery or mastectomy in addition to oncoplastic techniques. Sentinel lymph node biopsy is performed in all patients undergoing surgery. Adjuvant chemotherapy, radiotherapy or endocrine therapy can be used to treat concomitant invasive disease or ductal carcinoma in situ.

Abstract
Paget's disease of the breast is a rare type of cancer that affects the skin of the nipple and usually the areola. At the same time, most patients also have one or more tumors in the immediate vicinity of the focus of mammary Paget's disease. This tumor must be distinguished from normal or atypical Toker cells, and also differentiated from diseases such as Bowen's disease of the nipple and melanocytic lesions of the nipple and areola region, including nipple melanoma and BAP1-inactivated nevus (Wiesner nevus). Currently, there is no routine pathological diagnostic algorithm for these conditions. The aim of the work is to formulate a clear clinical and morphological algorithm for diagnosing Paget's disease of the breast and Toker cells, Bowen's disease of the nipple and areola, as well as melanoma and BAP1-inactivated nevi of the above localizations. Surgical material obtained from patients with Paget's disease of the breast (18), Toker cells of the nipple (2), Bowen's disease of the nipple (6), melanoma of the nipple (1), BAP1-inactivated nevus (1) was studied. The material was examined histologically with hematoxylin and eosin staining, Alcian blue and PAS reaction, as well as immunohistochemically with the following panel of antibodies: CD138, p53, CK8, CK7, HER2/neu, EMA, HMB-45, Melan A, S-100, p63, p16 and BAP1. An easy-to-learn pathoanatomical algorithm for diagnosing Paget's cancer has been developed, which will be especially useful for pathologists who encounter pathology of the nipple and areola in their work.

Abstract
ABSTRACT Paget disease of the breast is a rare form of breast cancer that affects the nipple and areolar complex. Clinicians should have a high suspicion for this condition in patients who fail conservative treatment for benign-appearing dermatologic findings regardless of age or sex. This article describes a patient with whose presumed nipple infection was initially thought to be related to her nipple piercing.

Abstract
BACKGOUND This study aims to identify the expression of lipoma preferred partner (LPP) in Paget disease (PD) and to further understand the pathogenesis of PD. METHODS Tissue microarray was used to evaluate the expression of LPP by immunohistochemistry in 40 PD patients. The results of LPP expression were combined with clinical and histopathological characteristics. Patient files were analyzed retrospectively. RESULTS Twenty-one cases were mammary Paget disease (MPD) and 19 extramammary Paget disease (EMPD) involving the vulva, scrotum, and penis. LPP was expressed in PD and this expression was significantly greater in MPD versus EMPD (P = .031). The expression of LPP in MPD was significantly related with age (P = .009) and expression of Ki-67 (P = .011). No statistically significant differences were observed in LPP expression as related to sex, body location, and time of PD diagnosis. CONCLUSIONS While LPP is expressed in both MPD and EMPD, the intensity of this expression is greater in MPD. LPP expression is positively correlated with Ki-67 and is more prevalent in middle-aged versus senior MPD patients. Further research is needed to determine its potential role in tumorigenesis and distribution.

Abstract
PURPOSE Paget's disease (PD) of the breast is an uncommon disease of the nipple usually accompanied by an underlying carcinoma, often HER2 + , and accounting for 0.5-5% of all breast cancer. To date, histogenesis of PD of the breast remains controversial, as two theories-transformation and epidermotropic-have been proposed to explain this disease. Currently, animal models recapitulating PD of the nipple have not been described. METHODS HER2-enriched DT13 breast cancer cells were injected into the mammary fat pad of NOD scid gamma null (NSG) female mice. Immunohistochemical staining and pathological studies were performed on tumor samples, and diagnosis of PD of the nipple was confirmed by expression of proteins characteristic of Paget cells (epidermal growth factor 2 (HER2), androgen receptor (AR), cytokeratin 7 (CK7), cytokeratin 8/18 (CK8/18), and mucin 1 (MUC1)). In addition, DT13 cells grown in 2D culture and in soft agar assays were sensitive to in vitro treatment with pharmacological inhibitors targeting Her2, adenylyl cyclase, mTOR, and PI3K signaling pathways. RESULTS Mice developed tumors and nipple lesions that were detected exclusively on the tumor-bearing mammary fat pad. Tumor cells were positive for proteins characteristic of Paget cells. In vitro, DT13 cells were sensitive to inhibition of Her2, adenylyl cyclase, mTOR, and PI3K signaling pathways. CONCLUSIONS Our results suggest that injection of HER2 + DT13 cells into the mammary fat pad of NSG mice recapitulates critical aspects of the pathophysiology of PD of the nipple, supporting the epidermotropic theory as the more likely to explain the histogenesis of this disease.

Abstract
The objective of this study was to investigate the clinicopathological characteristics and survival outcomes of Paget disease (PD), Paget disease concomitant infiltrating duct carcinoma (PD-IDC), and Paget disease concomitant intraductal carcinoma (PD-DCIS). We identified 501,631 female patients from 2000 to 2013 in the Surveillance, Epidemiology, and End Results (SEER) database. These identified patients included patients with PD (n = 469), patients with PD-IDC (n = 1832), and patients with PD-DCIS (n = 1130) and infiltrating ductal carcinoma (IDC) (n = 498,076). Then, we compared the clinical characteristics of these patients with those who were diagnosed with IDC during the same period. The outcomes of these subtypes of breast carcinoma were different. Based on the overall survival, the patients with PD-IDC had the worst prognosis (5-year survival rate = 84.1%). The PD-DCIS had the best prognosis (5-year survival rate = 97.5%). Besides, among patients with Paget disease, the one who was married had a better prognosis than who were not. And, according to our research, the marital status was associated with the hormone receptor status in patients with PD-IDC. Among three subtypes of Paget disease, patients with PD-IDC had the worst prognosis. Besides, patients who were unmarried had worse outcomes. And the marital status of patients with PD-IDC is associated with hormone status. The observation underscores the importance of individualized treatment.

Abstract
Extramammary Paget's disease (EMPD) is a rare disease which is found in apocrine-rich locations such as anogenital region, axilla and rarely in other sites. Perianal EMPD is often reported as the involvement of perianal skin, but involvement of anal mucosa is very rare. Based on pathogenesis and association with either synchronous or metachronous malignancy, EMPD can be divided into primary and secondary types. Treatment approach for these two types of Paget's disease and their prognosis is different, thus it is important to make the distinction. Secondary type of Paget's disease is almost always described in association with invasive malignancy. While secondary Paget's disease arising in association with ductal carcinoma in situ of the breast is common, secondary EMPD associated with precursor lesion of the rectum without invasion is exceedingly rare. We report a very rare case of secondary Paget's disease of the anal canal in association with rectal tubular adenoma (precursor lesion) without malignancy.

Abstract
We report a case of scrotal apocrine adenocarcinoma in a 72-year-old Caucasian male which was initially presented as a reddish superficial lesion which in time became an ulcerated nodule. The initial pathological examination showed an apocrine adenocarcinoma with pagetoid phenomenon. The tumor recurred after four months and then excision biopsy showed tumor with pagetoid phenomenon which reached all the surgical margins. Three months later an ulcerated nodule in the scrotum and greatly enlarged ipsilateral inguinal lymph nodes were noticed. The final pathological examination showed multiple separated malignant foci, some with overlying pagetoid phenomenon and inguinal lymph node metastases. Immunohistochemistry showed positivity for Gross Cystic Disease Fluid Protein-15 (GCDFP-15), androgen receptors, and score 3+ for the Human Epidermal growth factor Receptor-2 (HER2). The aggressive behavior of the present tumor goes along with previous reports showing that HER2 high score cases exhibit a worse prognosis.

Abstract
Paget's disease, described by Sir James Paget in 1874, is classified as mammary
and extramammary. The mammary type is rare and often associated with intraductal
cancer (93-100% of cases). It is more prevalent in postmenopausal women and it
appears as an eczematoid, erythematous, moist or crusted lesion, with or without
fine scaling, infiltration and inversion of the nipple. It must be distinguished
from erosive adenomatosis of the nipple, cutaneous extension of breast
carcinoma, psoriasis, atopic dermatitis, contact dermatitis, chronic eczema,
lactiferous ducts ectasia, Bowen's disease, basal cell carcinoma, melanoma and
intraductal papilloma. Diagnosis is histological and prognosis and treatment
depend on the type of underlying breast cancer. Extramammary Paget's disease is
considered an adenocarcinoma originating from the skin or skin appendages in
areas with apocrine glands. The primary location is the vulvar area, followed by
the perianal region, scrotum, penis and axillae. It starts as an erythematous
plaque of indolent growth, with well-defined edges, fine scaling, excoriations,
exulcerations and lichenification. In most cases it is not associated with
cancer, although there are publications linking it to tumors of the vulva,
vagina, cervix and corpus uteri, bladder, ovary, gallbladder, liver, breast,
colon and rectum. Differential diagnoses are candidiasis, psoriasis and chronic
lichen simplex. Histopathology confirms the diagnosis. Before treatment begins,
associated malignancies should be investigated. Surgical excision and
micrographic surgery are the best treatment options, although recurrences are
frequent.

Abstract
Paget's disease of the breast is uncommon and patients may present with nipple discharge, eczema, plaque or nipple destruction with or without a lump. The aim of the present study was to evaluate the presentation, clinicopathological features and treatment given for patients presenting with Paget's disease of the breast. We performed a retrospective analysis of medical records of patients who were treated at our centre for Paget's disease of the breast from 2006-2011. Twenty patients were treated in this period. Twelve patients had associated lump and eight patients did not have a lump in the breast. Two patients did not have a lump or any detected abnormality in mammography. Multicentricity was present in five patients. Diagnosis of malignancy was made by fine-needle aspiration cytology for patients with palpable lump and nipple wedge biopsy for patients with no lump. Modified radical mastectomy was done in 10 patients: 2 patients underwent total mastectomy and sentinel lymph node biopsy and 8 patients underwent central quadrantectomy and sentinel lymph node biopsy. Eleven patients had invasive ductal carcinoma, one patient had ductal carcinoma in situ with foci of invasion and eight patients had ductal carcinoma in situ. Seven patients had lymph node metastases. Three patients had recurrence, one had local recurrence and two had distant recurrences. The mean follow up period was 28 months (range 15-64 months). Paget's disease of the breast is a rare entity and one needs imaging and biopsy to diagnose these patients as they have associated cancer. They can be considered for breast conservation surgery with good cosmetic and oncological results.

Abstract
Patients with ostomy including urinary stoma often develop peristomal complications, especially skin damage. The patient in this case was a 69-year old female with a history of urothelial carcinoma of the bladder and left ureter who underwent transurethral resection of a bladder tumor, nephroureterectomy and cystectomy combined with ureterocutaneostomy. Later, she had recurrence of urothelial carcinoma in the remaining ureter that spread to the peristomal epidermis, with a skin appearance resembling Paget’s disease. We report this case based on its clinical significance since we believe it is the first description of this condition in the literature.

Abstract
Neuregulin (NRG; heregulin) is overexpressed in ∼30% of breast cancers and mediates various processes involved in tumor progression, including tumor cell migration and invasion. Here, we show that NRG mediates its effects on tumor cell migration via PKD1. Downstream of RhoA, PKD1 can prevent directed cell migration through phosphorylation of its substrate SSH1L. NRG exerts its inhibitory effects on PKD1 through Rac1/NADPH oxidase, leading to decreased PKD1 activation loop phosphorylation and decreased activity toward SSH1L. The consequence of PKD1 inhibition by NRG is decreased binding of 14-3-3 to SSH1L, localization of SSH1L to F-actin at the leading edge, and increased cofilin activity, resulting in increased reorganization of the actin cytoskeleton and cell motility. Our data provide a mechanism through which the Rho GTPase Rac1 cross-talks with PKD1 signaling pathways to facilitate directed cell migration.

Abstract
Background Breast-conserving therapy (BCT) is an accepted therapeutic option for most breast cancer patients. However, mastectomy is still performed in 30–50% of patients undergoing surgeries. There is increasing interest in preservation of the nipple and/or areola in hopes of achieving improved cosmetic and functional outcomes; however, the oncologic safety of nipple–areolar complex (NAC) preservation is a major concern. We sought to identify the predictive factors for NAC involvement in breast cancer patients. Methods We analyzed the rates and types of NAC involvement by breast carcinoma, and its association with other clinicopathologic features of the tumors in 787 consecutive therapeutic mastectomies performed at our institution between 1997 and 2009. Results Among these, 75 cases (9.5%) demonstrated NAC involvement. Only 21 (28%) of 75 of cases with NAC involvement could be identified grossly by inspection of the surgical specimen (seven of these had been clinically identified). NAC involvement was most significantly associated with tumors located in all four quadrants (P < 0.0001), tumors >5 cm in size (P = 0.0014 for invasive carcinoma and P = 0.0032 for in-situ carcinoma), grade 3 tumors (P = 0.0192), tumors with higher nuclear grades (P = 0.0184), and tumors with HER2 overexpression (P = 0.0137). Conclusions On the basis of our findings, we have developed a mathematical model that is based on the extent and location of the tumor, HER2 expression, and nuclear grade that predicts the probability of NAC involvement by breast cancer. This model may aid in preoperative planning in selecting appropriate surgical procedures based on an individual patient’s relative risk of NAC involvement.

APMIS 2010; 118: 777–81. The aim of this study was to determine the incidence of prostate cancer in patients with extramammary Paget’s disease (EMPD). All cases of EMPD diagnosed between 1992 and 2007 in Shanghai Cancer Hospital were collected and analyzed for the incidence of prostate cancer. The median follow-up was 78 months. In total, 38 cases of invasive and 10 cases of in situ EMPD had been registered. A second malignancy was found in 28.9% (11/38) of patients with invasive EMPD and in 30% (3/10) of patients with in situ EMPD. Patients had an increased risk of developing a second cancer compared with the general population (standardized incidence ratio: 1.7; 95% confidence interval 1.2–2.4). Sixteen patients had serum prostate-specific antigen (PSA) level above 4 ng/mL; five developed prostate cancer, three of them with PSA levels beyond 100 ng/mL. The incidence of prostate cancer is 10.4% in this patient group. Patients with EMPD were more likely to have prostate cancer than the general population. Although the prognosis of EMPD is fairly good, a thorough search for a second tumor is recommended.

Abstract
We reported a 52-year-old woman with an apocrine gland carcinoma of the mammary skin concomitant with pagetoid phenomenon. She had a 23-year history of a small nodular lesion on the lower left part of her right breast with a 1-year history of the pigmented plaque spreading peripherally around the nodule. Our diagnosis revealed that the nodule was an apocrine gland carcinoma and the intraepidermal neoplastic cells with pagetoid spread in the pigmented plaque were derived from the apocrine gland carcinoma. No Paget's cells were detected in the right nipple, and no tumor cells were observed in the sentinel lymph node and underlying mammary gland tissue. We also investigated the immunohistochemical changes in this case. They showed that both intraepidermal neoplastic cells with pagetoid spread and tumor cells of the apocrine gland carcinoma were positive with cytokeratin-7 and human epidermal growth factor receptor-2 (HER-2)/neu overexpression. The results of the present study conclude that the intraepithelial spread of tumor cells in the mammary skin distant from the nipple occurred as a pagetoid phenomenon, and that HER-2 may have a key role in pagetoid phenomenon of an underlying apocrine gland carcinoma, as well as in mammary Paget's disease.

Abstract
Paget disease of the nipple is a rare disease characterized by the presence of malignant glandular cells within the squamous epithelium of the nipple. The most common hypothesis to explain the development of Paget disease is an intraepithelial epidermotropic migration of malignant epithelial cells originating from an underlying intraductal carcinoma. If the immunohistochemical properties of the Paget cells in the nipple have been extensively studied, their proliferating characteristics remain paradoxically poorly studied. In the present study we have investigated the proliferating activity of Paget cells in the nipple by using double stain immunohistochemistry with both Ki67 (a protein which is expressed in all active parts of the cell cycle) and cytokeratin 7 (a highly sensitive marker of Paget cells). Ten cases of Paget disease and in their associated intraductal carcinomas (n = 10) and/or invasive carcinomas (n = 4) were tested. The mean Ki67 index was in Paget disease (26% +/- 10), in intraductal carcinomas (23% +/- 8) and/or in invasive carcinomas (20% +/- 8) (p > 0,05). This is the first report to convincingly demonstrate by specific double stain immunohistochemistry that Paget disease and underlying intraductal carcinomas share a close proliferating activity.

Abstract
Dendritic cells (DC) are the most potent antigen-presenting cells of the organism. They are specialized to capture, process, and present antigen via the MHC class II as well as the MHC class I pathways to CD4+ and CD8+ T cells, respectively. This results in T cell-mediated immune responses that are likely to counteract the generation and propagation of tumors in vivo. Therefore, we studied the distribution of dendritic cells in mammary Paget's disease. Paraffin-embedded samples of Paget's disease of the breast (n=27) and of disease-free epidermis of the nipple (n=10) were investigated immunohistochemically for the presence of dendritic cells, in particular of Langerhans cells, using antibodies against S-100, CD1a, and HLA-DR, as well as novel reagents against Langerin/CD207, DC-LAMP/CD208 and p55 (Fascin), the latter two being specific for mature dendritic cells. Paget samples presented a decrease of CD1a+, S-100+, and Langerin+ intraepidermal Langerhans cells in almost all cases. This was paralleled by a concentration of immature dendritic cells in the tumor-infiltrated tissue itself. Similar to infiltrating breast carcinoma we observed a marked increase of DC-LAMP+ and p55+ mature dendritic cells in the corial tissue beneath the tumor. These cells were almost always found in ribbon-like or nodular lymphocytic infiltrates. Moreover, rare mature dendritic cells were also found in the Paget cell-infiltrated epidermis of the nipple, i.e. in the tumorous lesion itself. These findings may indicate an effective ongoing anti-tumor immune response in this part of spreading breast cancer.

Abstract
The neuregulin family consists of four genes, NRG1-4 which can each encode products containing a domain related to the epidermal growth factor family of ligands. Each gene is subject to complex control of transcription and to splicing of their mRNA product to give many variant proteins. These do not contain secretory sequences but some, through their transmembrane sequence, are routed via the Golgi where they are glycosylated, to the cell surface. Here they may be released by regulated proteolysis to act as soluble proteins which can interact and activate members of the EGF receptor family of receptor tyrosine kinases. Other splice variants do not encode transmembrane sequences and these are found either in the cytoplasm or, if they encode a nuclear localisation sequence, in distinct compartments in the nucleoplasm. It has been shown that the variants containing a full EGF domain can act as receptor agonists but the function of the cytoplasmic and nuclear products is unknown as yet. All four neuregulin genes are expressed and play an important role in mammary gland development. They are also expressed at elevated levels in some cases of ductal carcinoma in situ of the breast and breast cancer. They seem to be active in this setting and their presence may affect the efficacy of treatment with endocrine agents or with signal transduction inhibitors directed at the EGF receptor family members. Much remains to be learned however of their normal function and their influence on breast cancer development, progression and response to therapy.

Abstract
DCIS is a heterogeneous group of non-invasive cancers of the breast characterized by various degrees of differentiation and unpredictable propensity for transformation into invasive carcinoma. We examined the expression and prognostic value of 9 biological markers with a potential role in tumor progression in 133 patients with pure DCIS treated with breast conserving surgery alone, between 1982–2000. Histology was reviewed and immunohistochemical staining was performed. Pearson correlation coefficient was used to determine the associations between markers and histopathological features. Univariate and multivariate analysis examined associations between time to recurrence and clinico-pathologic features and biological markers. Median age at diagnosis was 55 years (25–85). With a median follow up of 8.91 years, 41/133 patients recurred (21 as invasive recurrence). In this cohort 13.5% had low, 43% intermediate and 42% high nuclear grade. Comedo necrosis was found in 65% of cases. Expression of ER (62.4%), PR (55.6%), HER2/neu (31.6%), MIB1 (39.8%), p53 (22.6%), p21 (39.8%), Cyclin D1 (95.5%) calgranulin (20.5%), psoriasin (12%), was found in DCIS. HER2/neu was overexpressed in 45% that recurred as DCIS and 42.9% that recurred as invasive cancer, and only in 26.1% in cases that never recurred. On univariate analysis, HER2/neu overexpression was the only marker associated with an increased risk for any recurrence (p = 0.044). The hazard ratio for recurrence for HER2/neu positive DCIS was 1.927 (confidence interval 1.016–3.653) compared to HER2 negative DCIS. On multivariate analysis, HER2/neu overexpression remained the only independent variable significantly associated with any recurrence (p = 0.014) and with invasive recurrence (p = 0.044). This data suggest that HER2/neu testing may become an important parameter in the management of DCIS and the treatment of cases with positive HER2/neu status could be modified accordingly, similar to the current approach for HER2/neu positive invasive disease.

Abstract
Background Pagets disease of the nipple presents as an eczematous lesion, occurs in 1 – 4% of all female breast carcinoma cases and is invariably associated with underlying malignancy either overt or occult. The majority of these cases are invasive disease although 40–45% are associated with DCIS. Case presentation A 39 year old lady presented to our unit with a palpable lump in the right breast. Radiological and histological investigation proved this to be an extensive area of Ductal Carcinoma in Situ (DCIS) for which she underwent a simple mastectomy and immediate latissimus dorsi flap reconstruction. Histology revealed high grade DCIS with 2 small foci of invasive carcinoma. At 1 year the patient represented with a nodule adjacent to the reconstruction scar which was proved on biopsy to be consistent with Paget's disease. This was proved on formal excision. Conclusion In the absence of underlying breast or apocrine tissue this case details a case of Paget's disease of uncertain origin.

Abstract
Paget's disease is an intra-epidermal adenocarcinoma seen over the nipple/areola (mammary Paget's disease) or in extramammary body zones, such as the anogenital and perineal skin and the axilla. Mammary and extramammary Paget's disease share many common clinicopathological features but also show several differences, namely, with regard to pathogenesis and association with underlying malignancies. Indeed, mammary Paget's disease is as a rule associated with an underlying breast carcinoma whereas association of extramammary Paget's disease with underlying (skin or visceral) malignancies occurs much less frequently. We review here the main clinicopathological and therapeutic features of mammary and extramammary Paget's disease.

Abstract
In the central nervous system (CNS), neuregulin-1 (NRG-1) proteins function in neuronal migration, differentiation, and survival of oligodendrocytes. The NRG-1 gene codes for at least 15 different isoforms, which may be classified on the basis of their molecular structure. At least two different haplotypes of the NRG-1 gene may be associated with schizophrenia. An abnormal expression pattern of NRG-1 mRNA was found in the prefrontal cortex of schizophrenic patients in comparison to controls. We here show that the NRG-1alpha isoform is significantly reduced in white matter of the prefrontal cortex in schizophrenia but not in affective disorder. In the prefrontal gray matter, the density of NRG-1alpha expressing neurons was reduced in individuals with schizophrenia and in unipolar patients. We studied brains of 22 schizophrenics, 12 patients with affective disorders (7 unipolar and 5 bipolar), and 22 matched controls. NRG-1alpha immunoreactive material was detected with a polyclonal antiserum against the synthetic peptide from alpha-type EGF-like domain of human NRG. The demonstrated decreased number of NRG-1 immunoreactive neurons in the brains of schizophrenics and patients with unipolar depression points to an important role of this NRG-1alpha splice variant in neuropsychiatric disorders. Reduced NRG-1alpha protein concentrations were found in brains of schizophrenics after Western blot analysis. The diminished expression of NRG-1alpha strongly supports an early neurodevelopmental component to schizophrenia.

Abstract
Patients with human epidermal growth factor receptor 2 (HER-2) overexpressing breast carcinomas have a more aggressive clinical behavior and their tumors are often hormone receptor negative. However, the recently introduced anti-HER-2 antibody trastuzumab has been proven to improve the survival and controls the disease in a significant proportion of these patients. Therefore, the analysis of HER-2 in patients with breast cancer has become an important and routine test to select those who may benefit from the gene-based targeted therapy trastuzumab (herceptin). There is good correlation between HER-2/neu protein overexpression and HER-2 gene amplification in breast cancer. However, inconsistent results have been reported in the rate of HER-2/neu protein overexpression in other malignant neoplasms. Furthermore, only rare studies have investigated the correlation between the HER-2/neu protein overexpression and the status of HER-2 gene in these tumors. We investigated the HER-2 gene and protein status in several cases of Paget disease of the nipple and vulva by using a chromogenic in situ hybridization assay and immunohistochemistry. We find that the majority of the Paget disease of the breast demonstrate HER-2 gene amplification, whereas most of the extramammary Paget disease lack HER-2 gene amplification. In addition, our results show a good correlation between HER-2/neu protein overexpression and HER-2 gene amplification in Paget disease of the nipple, but we were unable to confirm this correlation in HER-2/neu protein overexpressing Paget disease of the vulva.

Abstract
AIM To investigate a possible follicular origin of extramammary Paget's disease (EPD). EPD is a predominantly intraepidermal tumour with extensive involvement of adnexal structures and high recurrence rates suggesting a follicular stem cell origin. Cytokeratin (CK) 15 and CK19 are considered markers for follicular stem cells located in the hair follicle bulge region. METHODS AND RESULTS Formalin-fixed paraffin-embedded tissues of 12 cases of primary EPD (three anal, nine vulvar) were studied immunohistochemically with antibodies to CK15 and CK19. All cases of EPD showed polygonal Paget cells in the interfollicular epidermis, hair follicles, sebaceous and apocrine glands distributed individually, in nests and in gland-like areas. The polygonal Paget cells were intimately associated with small, flat, mitotically active, 'compressed' keratinocytes. The large Paget cells uniformly expressed CK19 in 12/12 EPD. The small 'compressed' keratinocytes showed strong cytoplasmic CK15 staining in 9/12 EPD with focal accentuation, while the polygonal Paget cells were negative. CONCLUSIONS These histological and immunohistochemical observations allow the following conclusions: (i) the small, flat, 'compressed' keratinocytes are an integral part of EPD; (ii) the dual cell population is reminiscent of sebaceous glands with mature sebocytes and germinative keratinocytes; (iii) since both cell types express cytokeratins typical for follicular differentiation, EPD may be a proliferation of adnexal stem cells residing in the infundibulo-sebaceous unit of hair follicles and adnexal structures.

Abstract
BACKGROUND Paget disease is an uncommon presentation of breast cancer that increased in incidence in the U.S. between 1973 and 1987. Characterized by malignant crusting or ulceration of the nipple, Paget disease can present in 1 of 3 ways: 1) in conjunction with an underlying invasive cancer, 2) in conjunction with underlying ductal carcinoma in situ (DCIS), or 3) alone without any underlying invasive breast carcinoma or DCIS. Paget disease can be treated with breast conservation by undergoing central lumpectomy. The objective of this study was to determine how the incidence, presentation, biomarkers, operative approach, and outcome of Paget disease have evolved in the U.S. since 1988. METHODS Between 1988 and 2002, 1738 women who were diagnosed with Paget disease were reported in the 9 registries of the Surveillance, Epidemiology, and End Results Program. To the authors' knowledge, the current study on tumor characteristics, surgical intervention, and survival represented the largest series of Paget disease ever reported. RESULTS Although the overall incidence of breast cancer increased between 1988 and 2002, the incidence of Paget disease concomitantly decreased by 45% (95% confidence interval, from -35% to -53%). This decreasing incidence was greatest for Paget disease associated with invasive cancer or DCIS. Invasive cancer associated with Paget disease more commonly was estrogen receptor negative, progesterone receptor negative, and of high histologic grade. Even when 60% of the disease was located centrally, only 293 of 1642 patients with Paget disease (18%) who were treated surgically underwent central lumpectomy. Patients with Paget disease who underwent breast conservation had outcomes equivalent to the outcomes among patients who underwent mastectomy. CONCLUSIONS The incidence of Paget disease associated with underlying invasive cancer or DCIS decreased since 1988. Patients who underwent central lumpectomy and patients who underwent mastectomy for Paget disease had similar outcomes; nonetheless, most patients who were candidates for preservation underwent mastectomy.

Abstract
Based on current knowledge, biological factors that have been investigated in ductal carcinoma in situ (DCIS) include histology of these lesions, the impact of margin status on local recurrence, and several genetic alterations. Optimal integration of these factors in guiding optimal therapy is of great importance, since the incidence of DCIS is rising as a result of population-based mammographic screening. Mastectomy will almost always cure patients with DCIS but represents overtreatment for many. Less extensive treatment options should combine an optimal cosmetic result with the same safety for outcome of disease as mastectomy. To guide such optimal treatment, histological classification is not sufficient and additional biological factors are being investigated for their ability to predict outcome for individual patients with DCIS. In this review, the histological classification of DCIS is described and in addition the emerging knowledge on genetic alterations is summarised. For clinical management of DCIS patients, genetic or other biological factors should be identified that can predict the risk of progression of DCIS to invasive breast cancer and distant metastases. At present, insufficient knowledge on prognostic and predictive factors in DCIS is available. Research in this area is hampered by the difficulties in obtaining DCIS tumour tissue, as the tumour cells grow in the lumen of pre-existing ducts and lobules. As the recurrence rates are relatively low and the most relevant clinical endpoint, distant metastases, is indeed very rare, large numbers of patients (hundreds to a few thousand) need to be studied. Integration of translational studies into clinical trials aimed at optimising the treatment of DCIS are required to achieve this goal.

Abstract
Mammary Paget's disease and extramammary Paget's disease are rare intraepithelial neoplasms. Mammary Paget's disease is almost exclusively associated with underlying invasive breast carcinoma or high-grade ductal carcinoma in situ (DCIS G3). Extramammary Paget's disease arises in areas rich in apocrine glands and is suspected to have apocrine gland origin. The aim of the study was to investigate the presence of estrogen receptor (ER), progesterone receptor (PR), androgen receptor (AR) and Her2/neu in a large number of cases. We investigated 58 cases of mammary and 23 cases of extramammary Paget's disease. Formalin-fixed and paraffin-embedded tissues were analyzed using antibodies against AR, PR, ER and Her2/neu according to standardized procedures. In mammary Paget's disease, positive immunoreactions for Her2/neu, AR and ER were observed in 56 of 58 (97%), 51 of 58 (88%), and respectively in six of 58 (10%) cases. All cases of mammary Paget's disease were negative for PR and showed a coexpression of Her2/neu and AR in 51 out of 58 cases (88%). In extramammary Paget's disease, positive immunoreactions for AR, Her2/neu and ER were observed in 18 of 23 (78%), 12 of 23 (52%), and respectively in 1 of 23 (4%) cases. All cases of extramammary Paget's disease were negative for PR and showed a coexpression of AR and Her2/neu in 12 out of 23 cases (52%). In contrast to ER and PR, AR and Her2/neu are commonly expressed in mammary and extramammary Paget's disease. The knowledge about frequent expression of AR in Paget's disease could lead to the development of a new adjuvant therapy, particularly in patients with recurrent disease.

Abstract
The human epidermal growth factor (EGF) receptor (HER) family of receptor tyrosine kinases has frequently been implicated in cancer. Apart from overexpression or mutation of these receptors, also the aberrant autocrine or paracrine activation of HERs by EGF-like ligands may be important in cancer progression. Neuregulins constitute a family of EGF-like ligands that bind to HER3 or HER4, preferably forming heterodimers with the orphan receptor HER2. Mesenchymal neuregulin typically serves as a pro-survival and pro-differentiation signal for adjacent epithelia. Disruption of the balance between proliferation and differentiation, because of autocrine production by the epithelial cells, increased sensitivity to paracrine signals or disruption of the spatial organization, may lead to constitutive receptor activation, in the absence of receptor overexpression. Consequently, the analysis of ligand expression and/or activated receptors in tumor samples may broaden the group of patients that can benefit from targeted therapies.

Abstract
PURPOSE Extramammary Paget's disease (EMPD) is a rare intraepithelial neoplasm arising in skin that bears apocrine glands. We analyzed clinical, pathological and immunohistochemical staining patterns in 31 cases of EMPD to assess possible predictors of outcome, including patient age, sex, involved organs, surgical margin status, invasion depth, lymphovascular invasion, adnexal invasion, and immunoreactivity for cytokeratin 7 and 20, carcinoembryonic androgen, androgen receptor, p53, c-erbB-2 (Dako, Carpinteria, California) and Ki67. MATERIALS AND METHODS A total of 31 cases of EMPD were retrieved from the surgical pathology files of the department of pathology along with the medical records of the department of urology. Dermal invasion depth, tumor margin status, adnexal invasion and lymphovascular invasion were determined from the hematoxylin and eosin stained slides of each case. RESULTS Eight of the 31 cases (25.8%) experienced local recurrence. Two of 3 patients with and 6 of 28 without lymphovascular invasion experienced recurrence (p = 0.029). Dermal invasion significantly correlated with Her-2 over expression (Wilcoxon 2-sample test p = 0.0007). When the criteria of 1 and 5 mm invasion were applied, each validly correlated with Her-2 over expression. Her-2 over expression (grades 2 and 3) significantly correlated with p53 over expression (Wilcoxon rank test p = 0.0015). C-erbB-2 was positive in 51.6% of EMPD cases, in which it was strongly associated with dermal invasion and p53 over expression. CONCLUSIONS The most valid prognostic factor in male EMPD for predicting late recurrence is lymphovascular permeation and marginal status.

Abstract
The assessment of breast cancer morphology remains an important element in the evaluation of prognosis and therapeutic planning for this disease. The tumour morphology reflects the molecular profile that produced it and consequently each can be predictive of the other.

Abstract
We evaluated p186Her2 overexpression and HER2 oncogene amplification in recurrent vulvar Paget's disease. We identified six patients with recurrent vulvar Paget's disease in our archives. The number of recurrences ranged from 1 to 11 over a time period of 1-168 months. Recurrences were evaluated immunohistochemically for p185Her2 overexpression with the HercepTest and for HER2 oncogene amplification with fluorescence in situ hybridization. p185Her2 overexpression was scored as 3 in two patients, as 2 in two patients, and as 1 in two patients. All patients with scores 2 and 3 showed HER2 oncogene amplification. Overexpression of p185Her2 and HER2 oncogene amplification appears to be common in recurrent vulvar Paget's disease.

Abstract
HER2 is a paradigm of a molecular target whose appropriate assessment is pivotal in the targeting of novel therapies for breast cancer, notably including Herceptin/Trastuzumab. Determining the correct levels requires immunohistochemical and molecular biological skills that are reproducible and measurable, coupled with a knowledge of the appropriate morphological and pathobiological context. Attaining these goals is not easy and laboratories testing for HER2 should maintain a high level of throughput of tests and engage in a recognized external quality assurance scheme. Fluorescence in-situ hybridization testing remains a particular challenge and there is a range of testing strategies. This testing forms the model for the identification of other novel molecular targets. In the future rapid throughput techniques such as real-time quantitative polymerase chain reaction (rqPCR), tissue microarrays or both should bring significant economies of cost and scale.

Abstract
Protein biomarkers suitable for the prevention of breast cancer must be extremely sensitive, easily detectable and highly correlated with the disease. They should be expressed in the reversible phase of carcinogenesis. Among the large number of candidate tumour-associated proteins, those related to the oestrogen/chorionic gonadotropin/insulin pathway seem to be of most interest because these can be causally implicated. They presumably are the first to express differently and are open to hormonal treatments. The biomarkers that give information on membrane receptor-modulated signal transduction should be considered as well. Up to now, only tamoxifen has shown some preventive activity, suggesting that the oestrogen pathway is useful indeed. Fenretinide and recombinant human chorionic gonatotropin (hCG) are also promising. But the financial requirements and the very long assessment periods largely prevent current research. This is precisely why we badly need to give priority to molecular biology research, in particular in the protein compartment There is widespread belief that advanced proteomics together with increased informatics can provide specific combinations of disease-related expression profiles that could identify high-risk groups with much more reliability and allow us to monitor preventive strategies.

Abstract
In a search for signaling molecules that act downstream of E-cadherin inactivation in cancer, we examined the expression and localization of E-cadherin-associated proteins in lobular carcinoma, in which the E-cadherin gene is frequently inactivated, and found that E-cadherin down-regulation correlated with the cytoplasmic localization of p120ctn. Similar cytoplasmic localization of p120ctn and growth factor-induced accumulation of tyrosine-phosphorylated p120ctn in the protrusive domain were observed in E-cadherin-deficient breast cancer cells. Down-regulation of endogenous p120ctn by RNA interference promoted stress fiber formation and induced a flattened morphology with an increase of Rho-GTPase activity; it also reduced the development of membranous protrusions and migratory activity in E-cadherin-deficient breast cancer cells. Inactivation of E-cadherin in cancer cells is associated with the conversion from epithelial to mesenchymal phenotype, which also occurs in physiological conditions such as developmental processes. Cytoplasmic localization of p120ctn accompanied by E-cadherin down-regulation was observed in mesoderm cells that had undergone epithelial-mesenchymal transition during early mouse embryogenesis. Collectively, our results suggest that cytoplasmic p120ctn may contribute to the invasive phenotype of E-cadherin-deficient breast cancer cells.
