Abstract
Breast cancer (BC) is the most common type of cancer in women to be diagnosed, and it is also the second leading cause of cancer death in women globally. It is the disease that causes the most life years adjusted for disability lost among women, making it a serious worldwide health issue. Understanding and interpreting carcinogenesis and metastatic pathways is critical for curing malignancy. Fascin-1 was recognized as an actin-bundling protein with parallel, rigid bundles as a result of the cross-linking of F-actin microfilaments. Increasing levels of fascin-1 have been associated with bad prognostic profiles, aggressiveness of clinical courses, and poor survival outcomes in a variety of human malignancies. Cancer cells that overexpress fascin-1 have higher capabilities for proliferation, invasion, migration, and metastasis. Fascin-1 is being considered as a potential target for therapy as well as a potential biomarker for diagnostics in a variety of cancer types. This review aims to provide an overview of the FSCN1 gene and its protein structure, elucidate its physiological and pathological roles, and throw light on its involvement in the initiation, development, and chemotherapeutic resistance of BC.

Abstract
Filopodia are cellular protrusions that respond to a variety of stimuli. Filopodia are formed when actin is bound to the protein Fascin, which may play a crucial role in cellular interactions and motility during cancer metastasis. Significantly, the noncanonical features of Fascin-1 are gradually being clarified, including the related molecular network contributing to metabolic reprogramming, chemotherapy resistance, stemness ac-tivity, and tumor microenvironment events. However, the relationship between biological characteristics and pathological features to identify effective therapeutic strategies needs to be studied further. The pur-pose of this review article is to provide a broad overview of the latest molecular networks and multiomics research regarding fascins and cancer. It also highlights their direct and indirect effects on available cancer treatments. With this multidisciplinary approach, researchers and clinicians can gain the most relevant in-formation on the function of fascins in cancer progression, which may facilitate clinical applications in the future.

Abstract
Introduction: Lymphomatoid Papulosis (LyP) is a lymphoproliferative disorder with typical histopathological criteria and a spontaneous regression. Only few cases of oral involvement have been reported. We wondered about their clinical characteristics and their association with lymphoma. Method: This systematic review is conducted according to the PRISMA statement. The Oxford Centre for Evidence Based Medicine table (OCEBM) and the scoring from the National Agency for Accreditation and Assessment in Health (ANAES) was assigned to each study. Results: We have included 16 references. LyP can occur at any age with a female predilection. Oral lesions were unique ulcer and tongue was mostly affected. Histological types A, and C were dominant and LyP resolved spontaneously. 1 case was associated with a lymphoma. Discussion: Cutaneous LyP more affects men and are mostly classified as type A while those orals are type A or C. Oral LyP is probably a progressive lesion whose evolution is not illustrated by the histological aspect which often reflects only the initial acute period. Conclusion: Our literature review has shown that the epidemiological aspects between oral and cutaneous LyP are not the same. LyP may be associated with an increased risk of developing systemic lymphoproliferative disorders.

Abstract
Primary cutaneous T-cell lymphomas (CTCLs) are defined as lymphomas with a T-cell phenotype that present in the skin without evidence of systemic or extracutaneous disease at initial presentation. CTCLs other than Mycosis Fungoides (MF) and Sézary syndrome (SS) account for approximately one-third of CTCLs and encompass a heterogenous group of non-Hodgkin lymphomas ranging from indolent lymphoproliferative disorders to aggressive malignancies with a poor prognosis. The spectrum of CTCLs continues to broaden as new provisional entities are classified. Given the morphologic and histologic overlap among CTCLs and other diagnoses, a thorough clinical history, physical evaluation, and clinicopathologic correlation are essential in the workup and diagnosis of these rare entities. This article will summarize the epidemiologic, clinical, pathologic, and diagnostic features of CTCLs other than MF and SS.

Abstract
Lymphomatoid papulosis (LyP) is a benign chronic often relapsing skin condition that belongs to the CD30-positive cutaneous lymphoproliferative disorders. LyP typically presents as crops of lesions with a tendency to self-resolve, and morphology can range from solitary to agminated or diffuse papules and plaques to nodules or tumours. The clinical-histological spectrum can range from borderline cases to overlap with primary cutaneous anaplastic cell lymphoma (pcALCL). Histology and immunophenotype commonly show overlap with other CD30-positive disorders and sometimes may be identical to pcALCL, making its diagnosis more difficult. Patients with LyP have an increased risk of developing a second neoplasm such as mycosis fungoides, pcALCL and/or Hodgkin lymphoma. Clinical correlation allows its proper classification and diagnosis, which is fundamental for treatment and prognosis. This review focuses on the clinical appearance, histopathological features, diagnosis, differential diagnosis and management of LyP.

Abstract
Cutaneous CD30+ T-cell lymphoproliferative disorders (CD30+ T-LPD) represent a spectrum encompassing lymphomatoid papulosis (LyP), primary cutaneous anaplastic large-cell lymphoma (pcALCL) and borderline lesions. They share the expression of CD30 as a common phenotypic marker. They differ however in their clinical presentation, the histological features and clinical course. Moreover, LyP and PcALCL show numerous clinical, histological and phenotypic variants. Overlapping features of LyP and pcALCL with themselves and with other cutaneous and systemic lymphomas emphasize the importance of careful clinicopathologic correlation and staging in the diagnosis of CD30+ T-LPD. Furthermore, an increasing number of inflammatory and infectious skin disorders harboring medium-sized to large CD30+ cells have to be considered in the differential diagnosis. Whereas the expression of CD30 in cutaneous CD30+ T-LPD stands for a favourable prognosis, its expression in other cutaneous and systemic lymphomas has a divergent impact. The assessment of CD30 expression does not only provide prognostic information, but is of potential therapeutic relevance as CD30 can serve as a therapeutic target. This review focuses on the clinicopathological and phenotypic spectrum of CD30+ T-LPD, its differential diagnoses and the role of CD30 as a diagnostic, prognostic and therapeutic marker.

Abstract
CD30-positive cutaneous lymphoproliferative disorders, a group of T-cell neoplasms, including lymphomatoid papulosis (LyP) and cutaneous anaplastic large cell lymphoma, require careful clinicopathologic correlation for diagnosis. An association between LyP and the development of a second hematolymphoid malignancy has been established in the literature. LyP has also been reported with systemic amyloidosis, but no such reports have documented coexisting cutaneous amyloid deposition with LyP to our knowledge. A 66-year-old woman with cutaneous amyloidosis, secondary to multiple myeloma, in remission, presented with erythematous and dark-brown papules involving the right arm, scalp, and torso. Punch biopsy of the arm showed a dermal infiltrate of intermediate-sized lymphocytes, some of which displayed a plasmacytoid morphology and prominent nodular subepidermal amyloid deposition. Punch biopsy of the scalp similarly showed a nonepidermotropic dense dermal infiltrate of intermediate-sized plasmacytoid lymphocytes and multifocal amyloid deposition. Both infiltrates were immunophenotypically CD30-positive, anaplastic lymphoma kinase-negative T-cell lymphoproliferative processes. Subsequent studies showed no systemic involvement, and clinical correlation suggested a final diagnosis of LyP. We present this case of LyP, which histologically mimics a B-cell proliferation with a plasmacytoid morphology arising in association with cutaneous amyloidosis to highlight the importance of clinicopathologic correlation, a thorough battery of immunohistochemical studies, and consideration for a second hematologic malignancy arising in the setting of LyP.

Abstract
Lymphomatoid papulosis (LyP) refers to an indolent cutaneous lymphoma. The association of prognostic clinicopathological risk factors with a second hematologic malignancy has not yet been determined. We investigated the prognostic effect of clinicopathological characteristics on the occurrence of a second lymphoma, as well as the first-line treatment, in 24 patients diagnosed with LyP using logistic regression models. We showed that lymphoma occurrence was associated with a lower mean age at onset of LyP symptoms, histological types B and C, head-located LyP lesions and a higher frequency of LyP recurrences. In multivariate analyses, histologic type A was associated with a lower risk of second lymphoma (odds ratio [OR] = 0.12, 95% confidence interval [CI] 0.014-0.98; p = 0.045) adjusting for age of LyP first symptomatology, and an important increased lymphoma-free survival rate (long-rank test; p = 0.06). Clinicopathological characteristics are important in defining the clearance or persistence of LyP lesions and may predict the occurrence of a second lymphoma.

Abstract
Background The actin-bundling protein Fascin (FSCN1) is a tumor marker that is highly expressed in numerous types of cancer including lymphomas and is important for migration and metastasis of tumor cells. Fascin has also been detected in B lymphocytes that are freshly-infected with Epstein-Barr virus (EBV), however, both the inducers and the mechanisms of Fascin upregulation are still unclear. Results Here we show that the EBV-encoded oncoprotein latent membrane protein 1 (LMP1), a potent regulator of cellular signaling and transformation, is sufficient to induce both Fascin mRNA and protein in lymphocytes. Fascin expression is mainly regulated by LMP1 via the C-terminal activation region 2 (CTAR2). Block of canonical NF-κB signaling using a chemical inhibitor of IκB kinase β (IKKβ) or cotransfection of a dominant-negative inhibitor of IκBα (NFKBIA) reduced not only expression of p100, a classical target of the canonical NF-κB-pathway, but also LMP1-induced Fascin expression. Furthermore, chemical inhibition of IKKβ reduced both Fascin mRNA and protein levels in EBV-transformed lymphoblastoid cell lines, indicating that canonical NF-κB signaling is required for LMP1-mediated regulation of Fascin both in transfected and transformed lymphocytes. Beyond that, chemical inhibition of IKKβ significantly reduced invasive migration of EBV-transformed lymphoblastoid cells through extracellular matrix. Transient transfection experiments revealed that Fascin contributed to LMP1-mediated enhancement of invasive migration through extracellular matrix. While LMP1 enhanced the number of invaded cells, functional knockdown of Fascin by two different small hairpin RNAs resulted in significant reduction of invaded, non-attached cells. Conclusions Thus, our data show that LMP1-mediated upregulation of Fascin depends on NF-κB and both NF-κB and Fascin contribute to invasive migration of LMP1-expressing lymphocytes.

Abstract
Cutaneous CD30+ lymphoproliferative disorders are the second most common types of cutaneous T-cell lymphomas. They represent a well-defined spectrum encompassing lymphomatoid papulosis (LyP), primary cutaneous anaplastic large-cell lymphoma (pcALCL), and borderline lesions. They share the expression of CD30 as a common phenotypic hallmark, but they differ in their clinical presentation, course, and histologic features. New variants have been recently identified, including CD8+ epidermotropic LyP type D, angioinvasive LyP type E, and ALK-positive pcALCL. This review describes clinical, histopathologic, and phenotypic variants; their differential diagnoses (benign and malignant); and the role of CD30 as a diagnostic, prognostic, and therapeutic marker.

Abstract
The Society for Hematopathology and European Association for Haematopathology workshop, from October 27 to 29, 2011, in Los Angeles, CA, exhibited many exemplary skin biopsy specimens with interesting inflammatory changes mimicking features of cutaneous lymphoma. This article reviews features observed in cutaneous lymphoid hyperplasia, cutaneous drug reactions, lupus-associated panniculitis, pityriasis lichenoides, hypereosinophilic syndrome, histiocytic necrotizing lymphadenitis, traumatic ulcerative granuloma with stromal eosinophils, and pigmented purpuric dermatosis, as well as a brief review of the pertinent literature and discussion of submitted conference cases. For the pathologist, it is important to be aware of diagnostic pitfalls as well as the limitations of ancillary testing (eg, clonality studies). Finally, correlation with total clinical information, good communication with clinical colleagues, close clinical follow-up with rebiopsy, and prudent use of laboratory studies are vital and will likely offer the best path toward a correct diagnosis.

Abstract
AIMS Although the tumour cells of Hodgkin lymphoma (HL) are derived from mature B-cells, the lineage infidelity of Hodgkin/Reed-Sternberg cells (HRSs) often causes diagnostic problems. Recently introduced HRS markers are also positive for follicular dendritic cells (FDCs). We investigated the expression of several FDC markers in HL and anaplastic large cell lymphoma (ALCL) and evaluated their diagnostic efficacy. METHODS Eighty-five cases of HL and 52 cases of ALCL were included in this study. Immunohistochemistry was performed for glioma-associated homologue (GLI) 3, class III β-tubulin (TUBB3), fascin, clusterin, γ-synuclein, podoplanin, syntenin, CD21, CD35 and EGFR. RESULTS HRSs were diffusely positive for GLI3, fascin and TUBB3; the mean positivity rates per case were 94% for GLI3, 82% for fascin, 69% for TUBB3, 17% for clusterin, 17% for γ-synuclein and 14% for syntenin. Podoplanin, CD21, CD35 and EGFR were almost negative. However, the frequency of marker expression was not associated with the histologic subtype or the presence of Epstein-Barr virus (EBV). ALCL showed a similar pattern to HL, but the overall frequency of positivity was lower than that observed in HL. The mean positivity rates were 56% for GLI3, 62% for fascin, 58% for TUBB3 and 21% for clusterin. The other markers were nearly negative. Anaplastic large cell lymphoma kinase positivity did not affect the expression rates. CONCLUSIONS This study confirmed the frequent expression of FDC markers in HL and ALCL. Especially, GLI3, fascin and TUBB3 are the most sensitive markers. Further studies are required to evaluate the association between FDCs, HRSs and ALCL cells.

Abstract
The last classification of lymphomas of the World Health Organization in 2008 made a few changes from the preceding classification. Although useful, at the same time, it has posed new questions, concerns, and dilemmas which have been raised in the literature. The current report highlights some of these controversies, of each of these primary cutaneous entities, going through cutaneous mature T-cell and NK-cell neoplasms, mature B-cell neoplasms, precursor neoplasms, and other entities, which for several reasons do not fit in the previous categories. It also reviews some advances on many of these lymphomas published in the last 2 years.

Abstract
CONTEXT The year 2010 commemorates the 25th year since the seminal publication by Karl Lennert and Harald Stein and others in Kiel, West Germany, describing an unusual large cell lymphoma now known as anaplastic large cell lymphoma (ALCL). Investigators at many universities and hospitals worldwide have contributed to our current in-depth understanding of this unique peripheral T-cell lymphoma, which in its systemic form, principally occurs in children and young adults. OBJECTIVE To summarize our current knowledge of the clinical and pathologic features of systemic and primary cutaneous ALCL. Particular emphasis is given to the biology and pathogenesis of ALCL. DATA SOURCES Search of the medical literature (Ovid MEDLINE In-Process & Other Non-Indexed Citations and Ovid MEDLINE: 1950 to Present [National Library of Medicine]) and more than 20 years of diagnostic experience were used as the source of data for review. CONCLUSIONS Based on immunostaining for activation antigen CD30 and the presence of dysregulation of the anaplastic lymphoma kinase gene (2p23), the diagnosis of ALCL has become relatively straightforward for most patients. Major strides have been made during the last decade in our understanding of the complex pathogenesis of ALCL. Constitutive NPM-ALK signaling has been shown to drive oncogenesis via an intricate network of redundant and interacting pathways that regulate cell proliferation, cell fate, and cytoskeletal modeling. Nevertheless, pathomechanistic, therapeutic, and diagnostic challenges remain that should be resolved as we embark on the next generation of discovery.

Abstract
Cutaneous lymphoid infiltrates may pose some of the most difficult diagnostic problems in dermatopathology. Immunocytochemistry is often employed in an effort to determine whether an infiltrate is neoplastic or, in the case of clearly malignant infiltrates, to provide a specific diagnosis. The rarity of these disorders and the variant immunocytochemical profiles they may present further thwart understanding and sometimes prevent an accurate diagnosis. In this review the common immunocytochemical profiles of various cutaneous lymphomas are presented and potential pitfalls and problems considered. Immunocytochemistry is not a diagnostic test but, as in other areas of histopathology, is a highly valuable tool that requires critical interpretation within a context: so applied, it is an indispensable part of the pathologist's arsenal in evaluating lymphoid infiltrates and defining different lymphomas.

Abstract
PURPOSE To report the clinicopathologic features of 3 patients with CD30(+) lymphoid proliferations of the eyelid. DESIGN Retrospective case series. PARTICIPANTS Patients with cutaneous CD30(+) lymphoproliferative lesions of the eyelid. METHODS Three patients with CD30(+) non-mycosis fungoides T-cell lymphoid infiltrates of the eyelid were identified. The histories, clinical findings, pathologic features including immunohistochemical staining, treatments, and outcomes were reviewed and compared. MAIN OUTCOME MEASURES Pathologic findings including immunohistochemical analysis. RESULTS The patients included an 81-year-old man, an 18-year-old man, and a 42-year-old woman with CD30(+) lymphoid proliferations of the eyelid and adjacent soft tissue. The first patient had an isolated crateriform eyelid lesion that was classified as lymphomatoid papulosis (LyP). The second patient had an isolated multinodular lesion of the eyelid that was classified as cutaneous anaplastic large cell lymphoma (cALCL). The third patient presented with eyelid edema with an underlying mass and was found to have widely disseminated anaplastic large cell lymphoma (ALCL). Diagnoses were dependent on clinical findings. CONCLUSIONS The CD30(+) lymphoid proliferations represent a spectrum of conditions ranging from indolent LyP, to moderately aggressive cALCL, to highly aggressive ALCL. Interpretation of the pathologic findings in CD30(+) lymphoid proliferations is based in part on clinical findings.

Abstract
Fascin is a 55-kDa globular protein that functions to organize filamentous-actin into parallel bundles. A role for fascin in cell migration has led to its study in many tumor types. In this report, we investigate fascin in astrocytomas. We show that fascin is expressed in astrocytes and in a panel of human astrocytoma cell lines. Immunofluorescence analysis demonstrates that fascin and the intermediate filament protein, glial fibrillary acidic protein (GFAP), are both expressed in the perinuclear region and within cytoplasmic processes of astrocytes and astrocytoma cells. Amino acid residues within the NH2 terminus of GFAP can undergo phosphorylation; these modifications regulate intermediate filament disassembly and occur during cytokinesis. We show that fascin and specific phosphorylated species of GFAP colocalize within dividing cells. Finally, we demonstrate that fascin co-immunoprecipitates with GFAP and that immunocomplex formation is preferential for GFAP phosphorylated at serine residues 8 and 13. These data show that fascin and GFAP are immunolocalized regionally within cells and tumors of astrocytic origin and suggest that their binding may occur during dynamic reorganization of intermediate filaments.

Abstract
Lymphomatoid papulosis is a rare disease with a worldwide incidence of 1.2 to 1.9 per 1 million. It affects all age groups with a peak incidence between 30 and 40 years and an apparent male predominance. Occurrence in childhood has also been described. Both the etiology and pathogenesis of the disease are unknown. The clinical presentation is extremely variable and frequently uncharacteristic. A papulonodular eruption, characterized by self-healing skin lesions appearing in crops can often be seen, particularly on extremities. We report on 17 patients, including 2 children. By detailing 6 cases we point out the variable morphologic manifestations, the different courses of disease and therapeutic options.

Abstract
A 70-year-old Japanese male presented with a 1-year history of skin tumors, which were diagnosed as primary cutaneous anaplastic large cell lymphoma (ALCL) because of the CD3(low+), CD4(+), CD25(+), CD30(+), CD45RO(+), CD71(+), HLA-DR(+), CD8(-), CD56(-), and NPM/ALK(-) phenotype and monoclonal T-cell receptor-rearranged property of tumor cells as well as the absence of systemic involvement. At this time, the tumor cell was positive for cutaneous lymphocyte-associated antigen (CLA) and TH(2) chemokine receptor CCR4. The eruption had repeatedly appeared and spontaneously regressed or regressed by virtue of several therapeutic modalities, including radiotherapy, interferon-alpha and chemotherapy, until the tumor cell invaded the gastric mucosa and spread to the peripheral blood 5 years later. Upon progression to the fatal leukemic change, the skin lesions inversely disappeared. Flow cytometric monitoring of the phenotype of peripheral blood and skin-infiltrating lymphocytes disclosed that the expression of CLA and CCR4 on the tumor cells was converted from positive to negative in association with the leukemic change. The altered expression of skin-homing receptors might change its clinical behavior.

Abstract
The role of histologic examination in lymphoma diagnosis has been called into question by proponents of new technologies, such as genomics and proteomics. We review the history and salient features of morphologic evaluation in lymphoid diseases, and discuss the general and specific limitations of mature ancillary techniques, such as immunohistochemistry, flow cytometry, and molecular studies. We then speculate on the future relationship between morphology and the new genomic and proteomic technologies as they become integrated into clinical practice.

Abstract
BACKGROUND The spectrum of diseases that constitute the CD30+ lymphomas, with lymphomatoid papulosis (LyP) at one end, and anaplastic large-cell lymphoma (ALCL) at the other end, shows variable morphology, immunophenotype, and clinical behavior. The border between these diseases is sometimes difficult to establish and there are many grey zones in their classification. METHODS We reviewed the clinical and research literature and guided by our experiences attempted to discern molecular and phenotypic criteria to improve the classification and identify molecular targets for therapy of CD30-positive cutaneous lymphomas. RESULTS Functional studies of ALCL cell lines clonally derived from LyP have revealed loss of growth inhibition by transforming growth factor beta (TGF-beta), due to TGF-beta receptor mutations. Studies of genetic variants of the CD30 promoter showed distinct microsatellite alleles associated with development of LyP and lymphoma progression. Studies of LyP and cutaneous ALCL tissues and cell lines suggest a dual role for CD30/CD30 ligand interactions in regression of LyP and progression to lymphoma. CD30 signaling activates NF-kappaB in cell lines derived from cutaneous ALCL but not anaplastic lymphoma kinase (ALK)-positive systemic ALCL in which growth arrest occurs through cell cycle inhibitor p21WAF1/Cip1. Other likely biomarkers of disease progression include differential expression of Bcl-2, fascin, cutaneous lymphocyte antigen, and T-cell receptor clonality. These may lead to improved classification, diagnoses, and therapeutic targets. CONCLUSIONS The current clinicopathologic classification of CD30+ cutaneous lymphoproliferative disorders is insufficient. Incorporating genetic and molecular criteria would better define the borders between benign/ malignant and aggressive/nonaggressive disorders.

Abstract
PURPOSE Basal-like phenotype tumors are frequently found among BRCA1 germ-line mutated breast carcinomas. They are biologically aggressive and have a tendency towards visceral metastasis when untreated. Nevertheless, it has been suggested that they respond to chemotherapy better than other types of tumors. Fascin expression has been associated with lung metastasis in breast cancer. The aim of this study was to determine whether basal-like phenotype and fascin were related in both sporadic and familial tumors and with prognosis in node-negative sporadic breast cancers. EXPERIMENTAL DESIGN 230 nonfamilial and 28 hereditary node-negative invasive breast carcinomas were immunohistochemically analyzed using tissue microarrays. Tumors that were estrogen receptor/HER2 negative and cytokeratin 5/6 and/or epidermal growth factor receptor positive were considered to have a basal-like phenotype. RESULTS A basal-like phenotype was found in 11.9% of sporadic cancers. Among patients not receiving adjuvant chemotherapy, a basal-like phenotype was associated with poor prognosis (P = 0.001, log-rank test) whereas no such association was found in patients receiving it. Tumors with a basal-like phenotype showed local recurrence (17.4%) or visceral metastasis (13%) but not bone metastasis (P = 0.001). Fascin expression was observed in 25.1% of sporadic invasive breast carcinomas and was associated with the basal-like phenotype, but not with prognosis or recurrence pattern. Fascin was expressed in 83.3% and 16.7% BRCA1- and BRCA2-associated carcinomas, respectively (P = 0.048). CONCLUSIONS Basal-like tumors had a tendency towards visceral metastasis and their prognosis was dependent on the use of postoperative chemotherapy. Although fascin expression was associated with the basal-like phenotype, it was not associated with their metastatic behavior. Fascin expression is frequent in BRCA1-associated tumors.

Abstract
CD30+ lymphoproliferative disorders of the skin (CD30+ LPD) represent a well-defined spectrum of primary cutaneous T-cell lymphomas which have been recognized as distinct entities in recent lymphoma classifications. Lymphomatoid papulosis and anaplastic large-cell lymphoma share the expression of CD30 antigen as a common phenotypic hallmark but differ in regard to their clinical and histologic features as well as their biologic behavior. This article summarizes the histologic features of CD30+ LPD and presents recently identified new clinicopathologic variants of CD30+ LPD. There is an increasing number of reactive inflammatory disorders and neoplastic diseases which are composed of or contain a significant number of CD30+ cells and mimic LyP or anaplastic large cell lymphoma clinically or histologically. Differential diagnostic considerations focus on other lymphoproliferative processes with CD30+ tumor cells as well as non-lymphoid neoplasms and inflammatory simulators. The term CD30+ pseudolymphoma is proposed to designate inflammatory processes with CD30+ T cells. The final diagnosis of CD30+ LPD is based on a synthesis of clinical, histologic, phenotypic, and molecular genetic findings.

Abstract
A papulose linfomatóide (PL) constitui uma variante rara dos linfomas cutâneos de células T com a presença de amplo infiltrado intracutâneo de células T positivas para CD30. O exame histológico sugestivo de doença altamente maligna e agressiva opõe-se ao curso crônico-recidivante, muitas vezes auto-limitado, presente na maioria dos casos. São apresentados os relatos de dois pacientes. Uma mulher com 64 anos de idade e história de 10 anos de PL recebeu terapia Puva em creme, sendo a doença controlada. No segundo caso, uma mulher de 42 anos apresentava história de 18 anos de PL tratada com Puva e, posteriormente, com fotoquimioterapia extracorpórea (FEC). Durante a FEC, observou-se rápida disseminação metastática que não pôde ser controlada por poliquimioterapia. A paciente foi a óbito após um ano, em razão de metástase no sistema nervoso central.

Abstract
BACKGROUND The CD30-positive lymphoproliferative disorders lymphomatoid papulosis (LyP), primary cutaneous anaplastic large cell lymphoma (C-ALCL), and systemic anaplastic large cell lymphoma (S-ALCL) are lesions that overlap clinically, histopathologically, and immunophenotypically. Their biologic behaviors, however, vary considerably. In particular, lesions of LyP regress spontaneously while those of S-ALCL persist and often progress. Apoptosis has been suggested as the mechanism by which the lesions of LyP regress, but the underlying signaling pathways remain unclear. In this study, we used newly developed activation state-specific antibodies to demonstrate apoptosis signaling through the death receptor-mediated pathway regulated by FADD and caspase 3. METHODS Dual immunohistochemistry for CD30 and activated forms of FADD and caspase 3 was performed on cutaneous biopsy specimens from 27 patients with CD30-positive lymphoproliferative disorders involving the skin. The patients included 18 with primary cutaneous CD30-positive LPDs (15 with LyP and 3 with C-ALCL) and 9 with S-ALCL. RESULTS The proportion of CD30-positive cells expressing activated FADD was significantly different between primary cutaneous CD30-positive lymphoproliferative disorders and S-ALCL (36.4% vs. 14.5%, P = 0.0083). Expression of cleaved caspase 3 was also significantly different between primary cutaneous lesions and S-ALCL (9.2% vs. 1.9%, P = 0.048). CONCLUSIONS Although a larger number of cases should be studied to validate these results, these data provide evidence that differences in signaling through the death-receptor apoptosis pathway mediated by FADD may be responsible for the varying biologic behaviors of CD30-positive lymphoproliferative disorders involving the skin.

Abstract
Cell protrusions are outward extensions of the plasma membrane of individual cells that function in sensing the cell environment and in making initial, dynamic adhesions to extracellular matrix and other cells. Cell protrusions can be grouped into two major categories on the basis of morphology: localized, finger-like structures of highly defined shape and various lengths; or broad, irregular extensions of the plasma membrane. A key requirement of all cell protrusions is the need for a rigid cytoskeleton to support the localized extension of the plasma membrane. This is achieved either by a core unipolar bundle of actin microfilaments in finger-like protrusions, or by a combination of radial, rib-like, actin bundles integrated with a dendritic meshwork of microfilaments in the broad, lamellipodial protrusions. From studies of multiple cell types in vertebrates and invertebrates, fascin-1 has emerged as an actin-bundling protein of general importance for a diverse set of cell protrusions with functions in cell adhesion, cell interactions, and cell migration. This review discusses current knowledge of the molecular and cellular properties and functions of fascin, the roles of fascin-based protrusions in the cardiovascular system in health and disease, and areas of future interest.

Abstract
Primary cutaneous T-cell lymphomas represent a wide variety of non-Hodgkin lymphomas that are characterized by a distinct clinical presentation. Advanced molecular and biological techniques have enhanced the recognition of cutaneous T-cell lymphomas. The most common subtypes of cutaneous T-cell lymphomas are the epidermotropic variants mycosis fungoides and Sézary syndrome. At present, a stage-adjusted therapy is the best concept available, since early aggressive treatment options did not improve the prognosis of patients with cutaneous T-cell lymphomas. Accurate diagnostic and clinical assessment as well as identification of prognostic factors provides a helpful basis for treatment strategies. Current medical literature on diagnosis, prognosis, and treatment is reviewed with emphasis on new biologic response-modifying treatment options.

Abstract
Primary cutaneous T- and B-cell lymphomas are a heterogenous group of diseases with varied clinical presentations and prognosis. The use of new molecular, histological, and clinical criteria have enhanced the recognition of primary cutaneous T- and B-cell lymphomas. Compared to their nodal counterpart they have a different clinical behavior and therefore require a different treatment approach. Independent predictive factors identified clinically, histologically, and by immunopheno- and immunogenotyping are essential to assess the appropriate treatment for each subtype. The European Organization for Research and Treatment of Cancer (EORTC) Cutaneous Lymphoma Study Group provide a classification of cutaneous lymphomas taking into account of the histological and molecular features. Based on this classification we will provide a summary of the current medical literature in diagnosis, treatment, and prognosis for primary cutaneous lymphomas with emphasis on new treatment strategies.
