Abstract
Bcl-2 family protein plays an important role in apoptosis and its overexpression is protects neoplastic cell from apoptotic stimuli. Cutaneous B-cell lymphoma are rare non-Hodgkin lymphomas and can be classified in primary forms, featuring an exclusive skin-involvement at diagnosis, and cutaneous spread of a nodal disease. Such a distinction is not trivial, owing to different prognosis (indolent vs. aggressive) and therapeutic management. Bcl-2 expression at immunohistochemistry can be crucial in differential diagnosis between cutaneous and systemic disease, as well as between the different primary cutaneous forms. In the last few years, an animated debate on the prognostic role of Bcl-2 overexpression at molecular analysis have been developed in cutaneous B-cell lymphoma. To conclude, Bcl-2 expression have a diagnostic role more than prognostic in primary cutaneous B-cell lymphomas.

J Cutan Pathol 2020; 47:1103-1110.

Abstract
BACKGROUND Atypical cutaneous lymphoid infiltrates are challenging lesions in dermatopathology. We present a summary of the literature regarding kappa and lambda immunohistochemistry (IHC) and in situ hybridization (ISH) in the evaluation of atypical cutaneous or mucosal lymphoid infiltrates. METHODS Relevant articles from 1967 to 2018 in the English language were identified and summarized. In the absence of larger studies, case series of n ≥ 3 were included. RESULTS Sixty-three articles assessing kappa and lambda IHC and/or ISH were identified. Most focused on marginal zone lymphomas. Other lymphomas included follicle center lymphoma, diffuse large B-cell lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, mantle cell lymphoma, lymphoplasmacytic lymphoma, plasmablastic lymphoma, multiple myeloma, monoclonal gammopathy of undetermined significance, and polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes (POEMS). Non-neoplastic lesions included reactive lymphoid hyperplasia, cutaneous plasmacytosis, connective tissue disease, IgG4-related disease, acrodermatitis chronic atrophicans, Zoon balanitis, dermatitides, and infiltrates around epithelial dysplasias/neoplasias. CONCLUSION Kappa and lambda IHC and ISH are useful tools in the evaluation of cutaneous B-cell lymphomas and plasma cell neoplasms. The literature supports that the detection of light-chain restriction by IHC and ISH is one of the most useful findings in the differential diagnosis of reactive lymphoid hyperplasia vs B-cell lymphoma with plasmacytic differentiation.

Abstract
Primary cutaneous B-cell lymphomas comprehend a group of lymphoproliferative disorders characterized by being monoclonal proliferations of B-cell primarily involving the skin. Despite being recognized as autonomous and distinct clinico-pathologic entities since the late 80s, their classification is still an ongoing matter of debate. At the moment, WHO classification recognizes three disorders: primary cutaneous marginal zone lymphoma, primary cutaneous follicle center lymphoma and primary cutaneous diffuse large b-cell lymphoma (leg type). Primary cutaneous diffuse large b-cell lymphoma (other) has been used to define rare cases which show histologically an infiltrate with diffuse pattern composed by large b-cell, but not fitting with criteria for follicle center lymphoma nor for primary cutaneous diffuse large b-cell lymphoma (leg type). Aim of this review was to briefly describe all recognized and provisional entities included in the primary cutaneous b-cell lymphomas and to discuss recent acquisitions that may influence their future classifications.

Abstract
The term “Primary Cutaneous B-Cell Lymphoma” (PCBCL) comprehends a variety of lymphoproliferative disorders characterized by a clonal proliferation of B-cells primarily involving the skin. The absence of evident extra-cutaneous disease must be confirmed after six-month follow-up in order to exclude a nodal non-Hodgkin's lymphoma (NHL) with secondary cutaneous involvement, which may have a completely different clinical behavior and prognosis. In this article, we have summarized the clinico-pathological features of main types of PCBCL and we outline the guidelines for management based on a review of the available literature.

Abstract
Primary cutaneous marginal zone lymphoma (CMZL) is one of the major primary B-cell lymphomas of skin. Two types are recognized: a more common class-chain switched CMZL, and a much less common IgM+ CMZL. The extremely indolent course, together with other features distinct from most other MALT lymphomas, has led some to question whether at least the class-switched cases should be considered an overt lymphoma.

Abstract
The classification of cutaneous follicular lymphoma (CFL) into primary cutaneous follicle center lymphoma (PCFCL) or secondary cutaneous follicular lymphoma (SCFL) is challenging. SCFL is suspected when tumor cells express BCL2 protein, reflecting a BCL2 translocation. However, BCL2 expression is difficult to assess in CFLs because of numerous BCL2+ reactive T cells. To investigate these issues and to further characterize PCFCL, we studied a series of 25 CFLs without any extracutaneous disease at diagnosis, selected on the basis of BCL2 protein expression using 2 BCL2 antibodies (clones 124 and E17) and BOB1/BCL2 double immunostaining. All cases were studied using interphase fluorescence in situ hybridization with BCL2, BCL6, IGH, IGK, IGL breakapart, IGH-BCL2 fusion, and 1p36/1q25 dual-color probes. Nineteen CFLs were BCL2 positive, and 6 were negative. After a medium follow-up of 24 (6 to 96) months, 5 cases were reclassified as SCFL and were excluded from a part of our analyses. Among BCL2+ PCFCLs, 60% (9/15) demonstrated a BCL2 break. BCL2-break-positive cases had a tendency to occur in the head and neck and showed the classical phenotype of nodal follicular lymphoma (CD10+, BCL6+, BCL2+, STMN+) compared with BCL2-break-negative PCFCLs. Del 1p36 was observed in 1 PCFCL. No significant clinical differences were observed between BCL2+ or BCL2- PCFCL. In conclusion, we show that a subset of PCFCLs harbor similar genetic alterations, as observed in nodal follicular lymphomas, including BCL2 breaks and 1p36 deletion. As BCL2 protein expression is usually associated with the presence of a BCL2 translocation, fluorescence in situ hybridization should be performed to confirm this hypothesis.

Abstract
Cutaneous lymphoid infiltrates are diagnostically challenging. Although ancillary techniques to assess clonality can help distinguish between reactive lymphoid hyperplasia and lymphoma, one of the most widely used techniques in hematopathology, flow cytometry immunophenotyping (FCI), has not been routinely applied to skin specimens. We performed FCI on 73 skin specimens from 67 patients clinically suspected of having a cutaneous B-cell lymphoma (CBCL) and compared the results with those obtained from immunoglobulin heavy chain (IGH) gene molecular studies (58 cases, primarily by polymerase chain reaction) and either immunohistochemistry (IHC) or in situ hybridization to evaluate for light chain restriction (22 and 2 cases, respectively). Sufficient quantity of CD45 (leukocyte common antigen)-positive cells and staining quality were achieved in 88% of cases by FCI, and clonality was detected in 68% of CBCLs versus molecular studies showing sufficient DNA quality in 74% and only 39% clonality detection, and interpretable/contributory IHC results in 84% of cases with 55% clonality detection. Clonality was documented more frequently in secondary rather than primary CBCLs by all 3 techniques. Therefore, FCI is feasible and appears to be more reliable than molecular studies or IHC/in situ hybridization for detecting clonality in CBCLs and can provide additional prognostically and therapeutically relevant information. The exception is cases with plasmacytic differentiation such as marginal zone lymphoma for which IHC might be a superior tool. We have also shown that a large subset of primary cutaneous follicle center lymphomas express CD10 and/or BCL2 by FCI. Recent advances in FCI beg the question of applicability to cutaneous T-cell and NK-cell lymphomas.

Abstract
Background Primary cutaneous lymphomas (CLs), characterized by an accumulation of clonal T or B lymphocytes preferentially localized in the skin, have been successfully treated with interferons (IFNs) which counterbalance the Th2-immunosuppressive state associated with this pathology. In a phase I/II clinical trial, we correlated the local immune infiltrate and the anti-tumor effects of repeated intralesional administrations of an adenovirus vector expressing human interferon-gamma (IFN-g) termed TG1042, in patients with advanced primary cutaneous T-cell lymphomas (CTCL) or multilesional cutaneous B-cell lymphomas (CBCL). Methods For each patient, variation in time of specific lymphocyte populations, defined by immunohistochemical stainings, was assessed in biopsies of injected lesions. For each patient, the change in local immune response was associated with the patient’s objective response at the end of the study. Results Immunohistochemical analyses of biopsies indicate that infiltration of CD8+ T lymphocytes and of TIA-1+ cytotoxic T-cells in lesions injected with TG1042 correlates with clinical benefit. Conclusions These data suggest for the first time that a CD8+ cytotoxic infiltrate, induced by local expression of IFN-g correlates with a clinical response. Trial registration The phase I step (TG1042.01) does not have a registration number. The phase II step (TG1042.06) registration number was NCT00394693.

Abstract
BACKGROUND Primary cutaneous marginal zone B-cell lymphomas are low-grade lymphomas running an indolent course. Skin relapses have been frequently reported but little information about disease-free survival (DFS) is available. OBJECTIVE We sought to evaluate relapse rate and DFS in patients with primary cutaneous marginal zone B-cell lymphomas. METHODS Clinical features, European Organization for Research and Treatment of Cancer/International Society for Cutaneous Lymphomas stage, light chain restriction, clonality, treatments, skin relapses, DFS, stage progression, extracutaneous disease, and outcome are analyzed in a series of 137 patients. RESULTS Patients were classified as solitary lesion (T1) (n = 70; 51%), regional skin involvement (T2) (n = 40; 29%), and generalized skin lesions (T3) (n = 27; 20%). Surgical excision, local radiotherapy, or a combination were the initial treatment in 118 patients (86%). In 121 of 137 patients (88%) a complete remission was observed after initial treatment, including 99 of 106 patients (93%) with solitary or localized disease and 22 of 31 patients (71%) with multifocal lesions. Cutaneous relapses were observed in 53 patients (44%). Median DFS was 47 months. Patients with multifocal lesions or T3 disease showed higher relapse rate and shorter DFS. No significant differences were observed between surgery and radiotherapy, but surgery alone was associated with more recurrences at initial site. Overall survival at 5 and 10 years was 93%. Six patients (4%) developed extracutaneous disease during follow-up. LIMITATIONS This was a case series retrospective study. CONCLUSION Our results support long-term follow-up in patients with primary cutaneous marginal zone B-cell lymphomas. Disseminated skin lesions have higher relapse rate and shorter DFS suggesting further investigation on systemic therapies in such a group of patients.

Abstract
The diagnosis and classification of the cutaneous B-cell lymphomas can be quite a challenge, with a definitive diagnosis sometimes being elusive, even when an extensive workup has been performed. Distinction of benign from neoplastic disorders can be difficult, with some hyperplasias mimicking lymphomas and vice versa. There are only a limited number of skin-specific B-cell lymphomas, including primary cutaneous follicle center lymphoma and primary cutaneous diffuse large B-cell lymphoma, leg type. Cutaneous marginal zone lymphomas have distinctive features but are classified with the other mucosa-associated lymphoid tissue lymphomas. It is important, however, to also remember that many other B-cell lymphomas/ plasma cell neoplasms can primarily, or more often secondarily, involve the skin. Some may mimic one of the skin-specific lymphomas but have very different clinical implications. Iatrogenic and senescent immunodeficiency-associated lymphoproliferative disorders that are often Epstein-Barr virus (EBV) positive can also primarily involve the skin, including cases also known as EBV-positive mucocutaneous ulcer.

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.

The lymphomas of small B lymphocytes are a biologically diverse group of B cell derived neoplasms that includes B cell small lymphocytic lymphoma/chronic lymphocytic leukemia; mantle cell lymphoma; follicular lymphoma; nodal, splenic and extranodal marginal zone lymphomas; and lymphoplasmacytic lymphoma. They are distinguished from one another on clinical, morphological, phenotypic and genetic grounds. This article reviews the essential diagnostic and biologic features of these clinically indolent B cell malignancies.

Abstract
We report the case of a 79-year-old woman with a longstanding lymphedema of the right arm who developed a skin lymphoma involving the right wrist area. Microscopically, the lesion was composed of numerous centroblasts infiltrating both the dermis and the subcutaneous tissue. Phenotypic investigations showed expression of CD20, CD79a, and bcl-2 protein by neoplastic cells. In addition, these cells were CD5 positive. No expression of anaplastic large cell lymphoma kinase (ALK), CD10, CD23, CD30, CD43, bcl-6, cyclin D1, p53 or p16INK4a could be seen. Polymerase chain reaction (PCR) analysis demonstrated a clonal rearrangement of the genes coding for the kappa light chain of the immunoglobulin (Ig). No rearrangement of the genes coding for the Ig heavy chain, t(14;18) or t(11;14) chromosome translocations, or Epstein-Barr virus (EBV) genomic sequences could be found. The tumor was classified as stage IE and was first cured by complete surgical excision. Nineteen months later, a recurrence was noted in the right elbow area. This study further illustrates that lymphoma of the skin may complicate chronic limb lymphedema. Like most of the previously reported cases, this neoplasm belonged to the category of diffuse large B-cell lymphoma. However, it showed CD5 expression as a singular feature.

Abstract
Studies suggest that primary extranodal follicular lymphoma (FL) is not infrequent but it remains poorly characterized with variable histologic, molecular, and clinical outcome findings. We compared 27 extranodal FL to 44 nodal FL using morphologic, immunohistochemical, and molecular genetic techniques and evaluated the clinical outcome of these 2 similarly staged groups. Eight cases of primary cutaneous follicle center lymphoma were also studied. In comparison to nodal FL, a greater number of extranodal FL contained a diffuse growth pattern (P=0.004) and lacked CD10 expression (P=0.014). Fifty-four percent of extranodal and 42% of nodal FL cases showed evidence of t(14;18), with minor breakpoints (icr, 3'BCL2, 5'mcr) more commonly found in extranodal cases (P=0.003). Outcome data showed no significant differences in overall survival (P=0.565) and progression-free survival (P=0.627) among extranodal, nodal, and primary cutaneous follicle center lymphoma cases. Analysis of all cases by t(14;18) status indicate that the translocation-negative group is characterized by a diffuse growth pattern (P=0.043) and lower BCL2 expression (P=0.018). The t(14;18)-positive group showed significantly better overall survival (P=0.019) and disease-specific survival (P=0.006) in comparison with the t(14;18)-negative group. In low stage FL, the status of t(14;18) seems to be more predictive of outcome than origin from an extranodal versus nodal site.

Abstract
The expression of bcl-x(L), an antiapoptotic member of the bcl-2 family, has been correlated with poor prognosis in nodal follicular lymphomas (NFLs). So far, it has not been studied in primary cutaneous follicle center lymphomas (PCFCLs), which, compared with NFLs, express less frequently t(14;18)(q32;q21) and bcl-2. Using real-time PCR we measured bcl-xL and bcl-2 gene expression levels in laser-microdissected lymphoma cells of 20 PCFCL frozen sections. Numbers of apoptotic cells labeled by TUNEL assay were negatively correlated with bcl-xL expression levels (r=-0.840, P<0.005). Bcl-xL expression was significantly higher in biopsies of patients who developed relapse or disease progression later compared with patients who did not (P=0.022), and higher levels of bcl-xL gene expression were significantly correlated with shorter progression-free survival (PFS) (P=0.017). None of these features was correlated with bcl-2 gene expression levels. Our findings indicate that bcl-xL overexpression is inversely correlated with PFS in PCFCL. Moreover, the inverse correlation between bcl-xL expression levels and apoptotic cell numbers suggests that bcl-xL, through its antiapoptotic effect, might contribute to tumor cell survival in PCFCL.

Abstract
Primary cutaneous lymphomas are the second most common site of extranodal non-Hodgkin lymphoma. A specifically type named extranodal marginal zone B-cell lymphomas are indolent low-grade neoplasma. We report a case of a 42-year-old white man with multiple subcutaneous tumors located on the trunk and neck. The histopathological exam showed a non-epidermotropic, dense lymphocytic infiltrate. Histologic, immunohistochemical and cytologenetic analysis diagnosed primary cutaneous B-cell lymphoma MALT type. Investigation for other extranodal MALT lymphoma gastrointestinal tract, lung, salivary and thyroid glands was negative. The patient refused radiotherapy, but he accepted every 6 months close follow-up. Over a seven years period, we noticed a progressively disappearance of the skin lesions. The necessity of aggressive treatment of this disease with excellent prognosis is discussed. The treatment necessity of primary cutaneous B-cell lymphoma MALT type is discussed.

Abstract
CONTEXT Lymphoepithelial lesions (LELs) are a useful diagnostic feature of extranodal marginal zone B-cell lymphoma (EMZL); however, there is scant literature comparing their frequency and morphology at various sites. OBJECTIVE To evaluate any diagnostically useful, site-specific, morphologic patterns in EMZLs. DESIGN In this retrospective review, we evaluated 136 EMZLs from different sites for LEL pattern and other pathologic differences, including CD43 coexpression and plasma cell component features. RESULTS Prominent and destructive LELs were most common in salivary and thyroid gland cases, and LELs were rare to absent in breast, skin, and ocular adnexa cases. An LEL pattern with lymphocytes "stuffing" glandular lumina was seen in lung, thyroid, and salivary gland cases. Monoclonal plasma cells were most common in breast, upper aerodigestive tract, skin, and salivary gland cases. CD43 coexpression was seen in 36% of cases, most commonly in salivary gland, stomach, and upper aerodigestive tract. CONCLUSIONS The relative importance of LEL pattern, CD43 coexpression, and clonal plasma cell component in EMZLs is site-dependent, and the differences may aid in the diagnosis of EMZLs at different anatomic sites.

Abstract
The aim of the present study was to examine the clinicopathological presentations of follicular lymphomas (FL) of the salivary glands, as compared to mucosa-associated lymphoid tissue (MALT) lymphomas. A total of 27 primary salivary gland lymphomas were examined: 6 FL (five, grade 1; one, grade 2); 19 MALT lymphomas; and two diffuse large B-cell lymphomas. The FL patients ranged in age from 24 to 73 years, with a mean of 49 years, which was younger than that of MALT patients (mean: 64 years; P < 0.05). Four of the six FL arose from the submandibular gland, which was the origin of only five out of a total of 19 MALT lymphomas. One FL patient was in clinical stage (CS) IE, two in CS IIE, and two in CS III and IV. As regards the MALT lymphoma patients, 13 (68%) were in CS IE and five (26%) in CS IIE. None of the FL patients had clinical diagnosis of autoimmune disease but eight MALT lymphoma patients had autoimmune disease. The present study found a relatively high incidence of FL in the salivary glands. The observed differences in age of onset, background of autoimmune disease, and lesion site suggests that the pathogenesis of FL may differ from that of MALT lymphoma.

Abstract
Cutaneous abscesses can result from many conditions and are primarily managed with incision, drainage and antibiotics, without the need for extensive diagnostic workup. We herein report a case of a B-cell lymphoma manifesting as an abscess on the back of a 67-year-old female. Standard therapies failed to improve her condition, and, by the time of tissue diagnosis, a greater than palm-sized necrotic ulcer eroding through skin and fat, and into the psoas muscle had developed. Primary or secondary cutaneous B-cell lymphomas almost never lead to tissue necrosis but should be entertained in cases of abscesses or ulcers with unusual presentation.

Abstract
In contrast to nodal follicular lymphoma, limited data exist on genetic changes in primary cutaneous follicular lymphoma (primary cutaneous follicle center lymphoma according to WHO-EORTC). The detection rate of the BCL2 rearrangement, representing the characteristic t(14;18)(q32;q21) underlying follicular lymphoma, by polymerase chain reaction (PCR) has been reported to vary over a wide range (0%-41%), and only a few cases have been studied by molecular cytogenetic techniques such as fluorescence in situ hybridization (FISH). In this study, 27 primary cutaneous follicle center lymphomas were analyzed by FISH and the results compared with those obtained by PCR. FISH demonstrated translocations affecting the immunoglobulin heavy chain locus (IGH) in 14 of 27 cases (52%): a t(14;18)(q32;q21) involving BCL2 was found in 11 cases (41%), a t(3;14)(q27;q32) affecting BCL6 in 2 cases (7%), and in 1 case the partner gene of IGH could not be identified. Interestingly, PCR did not detect BCL2 rearrangement in any case. These data suggest that the t(14;18)(q32;q21) frequently occurs in primary cutaneous follicular lymphoma. The reason(s) why BCL2 rearrangements escape the detection by PCR is (are) not clear but could be due to BCL2 mutations, breakpoints outside the amplified DNA, or a high load of somatic mutations.

Abstract
To clarify the confusion surrounding the diagnosis of cutaneous lymphoid hyperplasia (CLH) that was formerly described as lymphadenosis benigna cutis, lymphocytoma cutis, or lymphocytic infiltration of Jessner and to assess whether newly recognized diagnoses, such as cutaneous marginal zone lymphoma and pseudolymphomatous folliculitis (PLF), may have been overlooked, we reexamined 55 Japanese cases of nonepidermotropic lymphoproliferative disorder that had previously been diagnosed as "cutaneous pseudolymphoma." In all these cases, the immunohistochemical expressions of CD1a, CD3, CD4, CD8, CD20, CD21, CD30, CD43, CD56, CD68, CD79a, kappa and lambda chains, S-100 protein, and latent membrane protein were assessed. In addition, in 13 cases the gene rearrangement of the immunoglobulin heavy chain was investigated using a polymerase chain reaction method. As a result of these investigations, we have identified 4 cases of cutaneous marginal zone lymphoma, 19 cases of PLF, 1 case of diffuse large B-cell lymphoma, and 2 cases of solitary nonepidermotropic pseudo-T-cell lymphoma, with the remaining 29 cases being CLH. Cutaneous marginal zone lymphoma, which represented 7.3% of the total, was distinguished from CLH by the presence of patchy or diffuse proliferation of centrocyte-like cells, plasma cells at the periphery of the lymphocytic infiltration, monotypic restriction of the light chains, and gene rearrangement of the immunoglobulin heavy chain. Pseudolymphomatous folliculitis was identified by the presence of activated pilosebaceous units with abundant CD1a-and S-100 protein-positive T-cell-activated dendritic cells. Of the cases that were reassessed, 34.5% were PLF.

Abstract
In contrast to nodal large B-cell lymphomas, recurrent chromosomal aberrations have been studied only in a small number of cases of primary cutaneous diffuse large B-cell lymphoma (PCDLBCL). We investigated 25 PCDLBCLs (classified according to the WHO-EORTC classification into PCDLBCL, leg-type, 8; and PCDLBCL, other, 17), using an interphase fluorescence in situ hybridization technique. All cases were analyzed for chromosomal aberrations commonly observed in nodal large B-cell lymphomas, including structural aberrations of the genes BCL2, BCL6, and c-MYC, and numerical aberrations of the chromosomes/genes 3, 7, 8, 11, 12, 13, 17, 18q, RB1, and p53. We observed genetic aberrations in 19 (76%) of 25 patients. The most frequent numerical aberrations were gains of chromosome 12 (7 of 25, 28%), 7 (5 of 25, 20%), 3 (5 of 25, 20%), 18q (3 of 25, 12%), 11 (3 of 25, 12%), X (3 of 25, 12%), and losses of chromosome/gene 17/p53 (3 of 25, 12%). BCL2, c-MYC, and BCL6 were rearranged with the IGH gene in 4 (16%), 1 (4%), and none (0%) of 25 cases, respectively. Most aberrations were homogeneously distributed among cases of PCDLBCL, leg-type and of PCDLBCL, other, cases located on the leg or at other body sites, cases with round and cleaved cell morphology, and Bcl-2+ and Bcl-2- cases. These results suggest that PCDLBCLs show similar chromosomal aberrations irrespective of classification, anatomic site, cell morphology, and Bcl-2 expression, and that many similarities between primary cutaneous and nodal diffuse large B-cell lymphomas can be observed.

Abstract
BACKGROUND Systemic B-cell lymphomas have been studied using microarrays, which has led to a better understanding of their molecular characteristics. Initial microarray studies of these lymphomas have implicated several genes as important predictors of outcome. In this study, we used a tissue microarray (TMA) to characterize primary cutaneous large B-cell lymphomas (PCLBCL). METHODS We studied 14 patients for whom clinical follow up was available, including four patients whose lesions were limited to the leg on presentation. Immunohistochemical staining with CD20, CD44, CD21, CD5, CD10, bcl-2, bcl-6, Ki67, p53, and multiple myeloma 1 (MUM1) was examined. RESULTS Our results identify two subgroups of lymphomas. The first group showed staining with bcl-6 and had an overall survival of 176 months (p = 0.003). The majority of this group was negative for MUM1. The second group lacked staining with bcl-6 and had an overall survival of 26 months, with a majority of these cases staining with MUM1. Three of four patients with PCLBCL of the leg showed no staining with bcl-6. CONCLUSIONS Our study demonstrates the utility of TMAs in the analysis of PCLBCL and that expression of bcl-6 and MUM1 correlates with survival.

Abstract
AIMS histological and clinical relationship study of 44 cases of primary cutaneous B cell lymphoma, classified according to WHO classification. MATERIALS AND METHODS histological, immunological and molecular analysis was correlated with clinical data. RESULTS 33 cases (75%) were marginal zone B-cell lymphomas (MZL), with head and trunk predominance (median age = 54 years). Relapses in other mucosa-related sites occurred in 3 patients. Histological transformation implied a more aggressive treatment in 3 cases. A favorable outcome was observed in most cases. 9 (20%) diffuse large B-cell lymphomas (DLBCL) appeared as a unique nodule, with female predominance (median age = 74 years) and 4 lymphoma-related deaths which seemed age-related (> 70 years) with only one lower limb localization. Histological aggressive features were present in 3 patients with a fatal outcome. 2 (5%) WHO grade 3 follicular lymphomas (FL) had an heterogeneous phenotype, with head localization, cutaneous relapses and good outcome. CONCLUSIONS MZL, the predominant type, has a good prognosis, although transformation can occur, needing a more aggressive treatment. DLBCL, observed in older patients, has clinical and histological prognostic factors identical to extra-cutaneous lymphomas. FL appears rare and has an heterogeneous phenotype. Relationships with its nodal counterpart remains unclear.

Abstract
Although primary cutaneous follicular lymphoma (FL) is considered a distinct variant of FL in the World Health Organization classification ("cutaneous follicle center lymphoma"), its biologic relationship to nodal FL remains controversial. The clinical, morphologic, immunophenotypic, and molecular cytogenetic features of 17 patients with primary cutaneous FL were studied and compared with 16 patients with secondary cutaneous FL. The head and neck region was the most frequent site at initial skin presentation in both the primary and secondary cases. Among the primary cases, 29% of the 31 biopsies were grade 1, 48% grade 2, 13% grade 3, and 10% grade 3 with diffuse large B-cell (DLBCL) areas. Among the secondary cases, 38% of the 29 skin biopsies were grade 1, 45% grade 2, 3% grade 3, and 7% grade 3 with DLBCL areas with two not evaluable. A floral-like pattern was observed in 32% of primary FL but only 5% of secondary cases. Histologic progression was found in 21% of patients. CD10 expression was demonstrated in 90% (27 of 30) of primary cases and 96% (22 of 23) of secondary cases. Bcl-6 was expressed in all cases tested. Bcl-2 expression was detected in 57% (17 of 30) of the primary cases (100% of grade 1, 43% of grade 2, 40% of grade 3), whereas all secondary cases were bcl-2 positive (P=0.0002). The t(14;18) translocation was identified by interphase fluorescence in situ hybridization (FISH) in biopsies from 31% (4 of 13) of the patients with primary FL compared with 77% (10 of 13) of those with secondary lymphoma (P <0.05). Seven of the 17 (41%) patients with primary disease had cutaneous relapse, including 1 who also developed nodal disease. Bcl-2 positivity was seen in 4 of these 7 patients. Eight of the 16 (50%) patients with secondary FL had cutaneous relapse. Primary and secondary cutaneous FL share many clinical and phenotypic features, but primary cases may have some distinctive morphologic features, more frequently lack bcl-2 protein, and often lack the t(14;18) translocation. These findings suggest that primary cutaneous FL are distinctive and often but not always have a pathogenesis different from most of nodal and secondary cutaneous FL.

Abstract
The skin is the second most common extranodal site for non-Hodgkin's lymphomas. Therefore, hematologists, pathologists, and dermatologists need to be familiar with these lymphomas. Primary cutaneous B-cell lymphomas are less common than T-cell lymphomas but have received much attention in the past few years. Their typical clinical and pathologic features are becoming clear. However, there is still some disagreement in terminology and characteristics of these lymphomas between the World Heath Organization (WHO) classification and the European Organisation for Research and Treatment of Cancer (EORTC) proposal for primary cutaneous lymphomas. This review will focus on the features of primary cutaneous B-cell lymphomas, compare and contrast areas of discordance between the WHO and EORTC systems, and outline areas for further investigation.

Abstract
Chromosomal translocations affecting the IGH locus and various oncogene loci are recurrent in many types of systemic B-cell lymphomas. Hardly any data exist, however, on such translocations in primary cutaneous B-cell lymphomas (PCBCL). Here, a series of 29 PCBCL was investigated by interphase fluorescence in situ hybridization with probes for the IGH, MYC, BCL6, and MLT1 loci. None of the six follicle center cell lymphomas and nine marginal zone lymphomas showed evidence for any translocation affecting these loci. In contrast, 11 of 14 large B-cell lymphomas of the leg harbored breakpoints in at least one of the loci. Translocations involving the MYC locus were detected in six cases, five of them derived from a MYC/IGH juxtaposition and one from a translocation involving a non-IG gene partner. Rearrangements of the BCL6 locus were detected in five B-cell lymphomas of the leg, and involved IGH (two cases), IGL (one case), and non-IG genes (two cases). This study shows that large B-cell lymphomas of the leg display a pattern of chromosomal translocations similar to their systemic counterparts whereas primary cutaneous follicle center cell lymphomas and marginal zone lymphomas lack these typical chromosomal translocations.

Abstract
Whether primary cutaneous follicular lymphoma (PCFL) may or not represent a cutaneous equivalent to nodal follicular lymphoma (FL) is not determined. We have therefore investigated a series of PCFL to determine if tumoral cells carry or not the t(14;18)(q32;q21) translocation, a cytogenetic hallmark of nodal FL. Thirty cases of PFCL were selected according to the criteria of both the European Organisation for Research and Treatment of Cancer and the World Health Organization with 21 cases classified as grade 1 or 2 and 9 cases as grade 3. First, cutaneous tumors were studied by PCR for the amplification of bcl-2/JH rearrangements and by interphase fluorescence in situ hybridization using a dual color probe spanning t(14;18) breakpoints. Second, we tried to determine the origin of bcl2-JH-positive cells by a parallel bcl2-JH and immunoglobulin heavy chain gene amplification of blood mononuclear cells DNA and of DNA extracted from single microdissected B cells. Bcl2-JH rearrangements were amplified by PCR in skin of 9 of 30 (30%) patients with a similar-sized bcl2-JH rearrangement detected in the blood of 7 of these 9 cases. No t(14;18) breakpoint was detected by interphase fluorescence in situ hybridization analysis of 11 bcl2-JH-negative and 5 bcl2-JH-positive PCFL in contrast with its detection in the secondary cutaneous FL and in the nodal FL cases. Single-cell/multigene analysis showed that no single monoclonal B cells of PCFL carried the bcl2-JH rearrangement. Bystander or nontumoral t(14;18)+ B cells emigrating from blood may account for the detection of bcl2-JH rearrangements within PCFL material. Our study also underlines the diagnostic value of interphase fluorescence in situ hybridization to discriminate between t(14;18)-negative PCFL and extracutaneous FL involving the skin.

Abstract
The most common subtypes of primary cutaneous B-cell lymphomas are marginal zone B-cell lymphoma/immunocytoma, follicle center cell lymphoma, and large B-cell lymphoma of the leg. Precise classification (European Organization for Research and Treatment of Cancer (EORTC) scheme) can be achieved only after a complete synthesis of clinical, histopathological, immunophenotypic, and molecular features. It is extremely important to emphasize that primary cutaneous B-cell lymphomas differ significantly from their nodal counterparts and are frequently characterized by an excellent prognosis. Awareness of this special clinical behavior should prevent the application of unnecessarily aggressive treatment protocols. Future definitions of primary cutaneous B-cell lymphomas will be based on their etiology and pathogenesis and especially on their molecular features. Some important areas are presented where exciting findings have been detected.

Abstract
Classification and subdivision of primary cutaneous diffuse large B-cell lymphoma (PCDLBCL) are a matter of ongoing debate. In this study we assessed the morphologic, immunophenotypic, and clinical features of 30 cases of PCDLBCL identified during a review of all primary cutaneous B-cell lymphomas in the Scotland and Newcastle Lymphoma Group database. We also determined the number of cases harboring t(14;18) using a polymerase chain reaction and primers to the major breakpoint cluster region. The effect on prognosis of a variety of clinical and pathologic factors was assessed for the group of 30 PCDLBCL and the 5-year disease-specific survival (DSS) of this cohort compared with that of 195 cases of stage I diffuse large B-cell lymphoma arising primarily in lymph nodes, also identified from within the Scotland and Newcastle Lymphoma Group database. Location on the leg was the only independent prognostic factor for determining outcome in PCDLBCL (67% 5-year DSS compared with 100% for the upper body; P = 0.0047). The presence of multiple lesions, involvement of more than one body site, and expression or not of CD10, bcl-2, bcl-6, and CD10 and bcl-6, had no effect on survival. Compared with cases arising above the waist, those on the leg were more often female, were of an older age, and had a significantly higher incidence of bcl-2 expression (P = 0.002) as well as the aforementioned poorer prognosis. They also showed more frequent co-expression of CD10 and bcl-6, supporting a follicle center cell origin for some, but this difference was not statistically significant. Although there was no significant difference in the 5-year DSS between the group of PCDLBCL and the cases of stage I nodal diffuse large B-cell lymphoma (88% 5-year DSS vs. 78%; P = 0.06), the latter were generally treated with more aggressive therapy. Moreover, a significant difference in 5-year DSS was seen when the nodal DLBCLs were compared with PCDLBCLs arising above the waist (78% vs. 100% respectively; P = 0.0135). These results support the current EORTC approach of subdividing PCLBCL on the basis of site to produce prognostically relevant groupings.

Abstract
BACKGROUND Primary cutaneous follicle centre cell lymphomas (PCFCCLs) are the most common type of cutaneous B-cell lymphoma. There is ongoing discussion on the origin of the neoplastic B cells in these PCFCCLs, and consequently on their relation to the groups of primary cutaneous marginal zone B-cell lymphomas (PCMZLs) and nodal follicular lymphomas. OBJECTIVES To define better the neoplastic B cells in PCFCCLs, and to find out if differences in the expression of the antiapoptopic protein Bcl-2, and Bcl-6 and CD10, molecules which are normally expressed by the neoplastic B cells in nodal follicular lymphomas, might have diagnostic or prognostic significance in cutaneous B-cell lymphoproliferative disorders. METHODS Pretreatment biopsies of well-defined groups of PCFCCL (n = 24), PCMZL (n = 14), primary cutaneous large B-cell lymphoma of the leg (PCLBCL-leg; n = 19), secondary cutaneous follicular lymphoma (n = 3) and cutaneous pseudo-B-cell lymphoma (n = 6) were investigated by immunohistochemistry for expression of Bcl-2, Bcl-6 and CD10. RESULTS The PCFCCLs consistently expressed Bcl-6, whereas CD10 and Bcl-2 were expressed in only one and two of 24 cases, respectively. In contrast, PCMZLs were always negative for Bcl-6 and CD10, but were Bcl-2 positive, whereas skin and lymph node localizations of secondary cutaneous follicular lymphomas consistently expressed all of Bcl-2, Bcl-6 and CD10. Reactive follicle centre cells in pseudo-B-cell lymphomas expressed Bcl-6 (six of six cases) and CD10 (five of six cases), but not Bcl-2. PCLBCL-leg was Bcl-6 positive and CD10 negative in all cases, irrespective of clinical outcome, and strongly expressed Bcl-2 protein in all but two cases. CONCLUSIONS The results of the present study provide further support for the follicle centre cell origin of both PCFCCL and PCLBCL-leg, and indicate that staining for Bcl-2, Bcl-6 and CD10 can serve as an important adjunct in the differential diagnosis of cutaneous B-cell lymphoproliferative disorders.

Abstract
PCBCL are a heterogeneous group of B-cell lymphomas that originate in the skin, with the absence of extracutaneous disease at diagnosis. Overall, these cutaneous lymphomas have an excellent prognosis. Recurrences are common but dissemination is rare. The EORTC classification allows a more uniform diagnosis and treatment of patients with PCBCL. Careful clinical and pathologic correlation is critical in confirming a diagnosis of PCBCL, before deciding on therapy. Several therapeutic options that are aimed at cure, are available. In most instances, chemotherapy should not be the first line of treatment.

Abstract
INTRODUCTION Primary cutaneous B-cell lymphoma (1 degrees CBCL) accounts for 25% of all lymphomas. The difficulty in distinction of reactive from neoplastic B-cell infiltrates prompts the use of molecular diagnostic adjuncts. While T-cell clonality can be seen in various reactive states, clonal B-cell infiltrates are often neoplastic; standard assays employed include polymerase chain reaction (PCR) or Southern blot analysis to assess heavy chain rearrangement. We sought to assess the utility of kappa (kappa) and lambda (lambda) mRNA expression using the Ventana automated assay (Ventana Medical Systems, Tucson, AZ, USA) in the analysis of atypical cutaneous B-cell lymphoid infiltrates. MATERIALS AND METHODS Multiple 4 micro m sections of paraffin-embedded, formalin-fixed skin biopsies from 31 patients with CBCL were placed on silane-coated slides, deparaffinized, then digested in pepsin (5 mg/ml) for 30 min at 37 degrees C. Fluorescein-tagged oligoprobes and tissue mRNA were denatured at 80 degrees C for 5 min, hybridized for 2 h at 37 degrees C, and incubated with antifluorescein alkaline phosphatase conjugates. Detection of the probe target complex employed nitroblue tetrazolium and bromochloroindolyl phosphate conjugates with a nuclear fast red counterstain. A kappa : lambda ratio > 3 : 1 was held to represent kappa light chain restriction and a kappa : lambda ratio </= 1 : 1 to indicate lambda light chain restriction. RESULTS The diagnosis in each case was determined by careful integration of clinical, histologic, and phenotypic data. The diagnoses included: pseudolymphoma (PL), marginal zone lymphoma (MZL), 1 degrees CBCL of the trunk, scalp or leg, 2 degrees lymphoma, and plasma cell dyscrasia. All but one case of lymphoma were light chain restricted. All cases of PL were proven to be polyclonal by this methodology. In non-plasmacytic small cell lymphomas, only 5-10% of the infiltrate expressed kappa or lambda, with clonality established through the abnormal kappa : lambda ratio. Interpretations were most difficult in the 2 degrees small cell-dominant follicular center cell lymphomas and easiest in cases with significant plasmacytic differentiation (i.e. MZL, immunocytomas, or plasma cell dyscrasias). CONCLUSION The Ventana kappa/lambda assay is a reliable, quick, and inexpensive way to determine B-cell clonality in cutaneous lymphoid infiltrates in paraffin-embedded formalin-fixed tissue.

Abstract
This chapter describes the various ways in which the non-Hodgkin's lymphomas can involve the skin, how these diseases should be assessed, standard treatments available in 2002, and new directions in research. The goal of the session is to succinctly review recent developments in lymphoma classification and treatment as they apply to the unique aspects of lymphoma when manifest in the skin. In Section I, Dr. Eric Hsi reviews the special characteristics of the lymphomas seen when they proliferate in the skin and the application of the new World Health Organization classification system to the cutaneous lymphomas, emphasizing the unique challenges of recognizing and correctly classifying these diseases. He summarizes the evidence in favor of including the skin lymphomas in the overall lymphoma classification scheme and concludes with a practical description of the specific skin lymphoma entities. In Section II, Dr. Joseph Connors describes the current optimal treatment of the B-cell lymphomas when they present in or metastasize to the skin. Building on the classification scheme described by Dr. Hsi, Dr. Connors outlines a treatment approach based on current understanding of pathophysiology of these diseases and application of each of the effective modalities available for cutaneous lymphoma including radiation, chemotherapy, and immunotherapy. In Section III, Dr. Francine Foss concludes the session with a discussion of the different T-cell lymphomas that start in or spread to the skin concentrating on mycosis fungoides, cutaneous anaplastic large cell lymphoma and peripheral T-cell lymphoma. She includes comments on the newer anti-T-cell chemo- and immuno-therapeutics focusing on agents and techniques specific for cutaneous T-cell lymphomas.

Abstract
BACKGROUND Large B-cell lymphoma (LBCL) of the leg is an uncommon subset of primary cutaneous B-cell lymphoma that has been described in a series of European patients. OBJECTIVE Our purpose was to evaluate the clinical manifestation, diagnostic histopathology, immunophenotype, clinical course, and response to treatment of LBCL of the leg. METHODS We conducted a retrospective case series of 3 patients with primary LBCL of the leg. RESULTS The 3 elderly patients presented with progressive erythematous nodules on bilateral or unilateral lower extremities. All 3 patients had pre-existing peripheral edema or peripheral vascular disease. Histopathologic examination of the nodules showed dense lymphocytic infiltrates composed predominantly of large dysplastic lymphocytes that marked as B cells (CD20(+)). In 2 cases, the neoplastic cells were BCL-2 positive. All patients responded to initial therapy with localized electron beam radiation and chemotherapy but had disease progression. One patient had a complete and durable second response to anti-CD20 monoclonal antibody (rituximab). CONCLUSIONS The patients described have similar clinical and histopathologic features to those previously described. There may be an association between LBCL and pre-existing lower-extremity vascular disease. Treatment of LBCL is difficult, but 1 patient responded well to systemic anti-CD20 monoclonal antibody.

Abstract
Cutaneous marginal zone B-cell lymphoma is a recently proposed entity and constitutes a cutaneous counterpart of extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT). Borrelia burgdorferi infection has been suggested as a possible causative agent in European cutaneous cases of marginal zone B-cell lymphoma, whereas API2-MALT1 fusion and BCL10 mutation are highly associated with MALT lymphoma. Aberrant nuclear BCL10 expression may be closely correlated with API2-MALT1 fusion in gastric and pulmonary MALT lymphomas. We examined 24 Asian cases of cutaneous marginal zone B-cell lymphoma for B. burgdorferi involvement, API2-MALT1 fusion, BCL10 cellular expression, and BCL10 mutation. Neither Borrelia DNA nor API2-MALT1 fusion transcript was detected. Nuclear BCL10 expression was evident in tumor cells of 11 of 24 cases, although BCL10 mutation was found in one case only. Clinicopathologically, nuclear BCL10 was more frequently expressed in macroscopically nodular lesions than in plaques or papules (p = 0.0031). These data suggest that 1) B. burgdorferi infection may not play an important role in developing cutaneous marginal zone B-cell lymphoma in Asian cases, 2) neither API2-MALT1 fusion nor BCL10 mutation is closely associated with the pathogenesis, 3) aberrant nuclear BCL10 may frequently be expressed in the absence of these genetic abnormalities, and 4) nuclear BCL10 expression may be clinically important because it was observed in locally aggressive tumors.

Abstract
Primary cutaneous B-cell lymphoma (PCBCL) is rare, with few series reported in the literature. Its classification and treatment remain controversial. Biopsy specimens of 13 patients with PCBCL were classified according to both the European Organization for Research and Treatment of Cancer (EORTC) and the new World Health Organization (WHO) classifications. Treatment and clinical outcomes were documented. Using the EORTC classification there were seven men and six women aged 32-85 years (mean = 51 years) with follicle centre cell (FCC) lymphoma (nine), immunocytoma (two) and primary cutaneous large B-cell lymphoma of the leg (PCLBCL-leg) (two). When the WHO classification was used, the nine patients with FCC were reclassified as follicle centre (five) and diffuse large B-cell lymphoma (four). Most patients had localized disease (12). Initial treatment consisted of radiotherapy alone (seven), combination chemotherapy alone (one), combined chemoradiotherapy (three) and surgery (two). Twelve patients achieved complete remission (median follow up 28 months, range 10-167 months). One patient with PCLBCL-leg died from progressive cutaneous disease. Most localized PCBCL lesions (except PCLBCL-leg) have a favourable prognosis. We recommend that clinicians be familiar with the important differences in the EORTC and WHO classifications. Further large prospective studies comparing the WHO and EORTC classifications are required to more clearly delineate the outcomes of the increasing number of patients who are classified as DLBCL by the WHO system.

Abstract
B-cell lymphomas comprise up to 25% of primary cutaneous non-Hodgkin lymphoma (NHL). Two main classification systems are used, namely the European Organization for Research and Treatment of Cancer (EORTC) and the World Health Organization (WHO) classification of tumours. Indeed, there is much controversy surrounding which classification system to use, which in turn influences the interpretation of existing data and subsequently how we manage patients with these conditions.

Abstract
The new World Health Organization (WHO) classification of hematopoietic and lymphoid malignancy represents the first worldwide consensus document on the classification of lymphoma/leukemia. Its aim is to supercede all existing classification systems, including the Revised European American Classification (REAL), and the organ-based classification of cutaneous lymphoma proposed in 1997 by the European Organization for Research and Treatment of Cancer (EORTC) cutaneous lymphoma project group. This article compares the REAL, EORTC, and WHO classifications with particular reference to cutaneous lymphoma. It identifies those entities that have been adopted from the EORTC classification, and illustrates important new entities in the category of cytotoxic T-/NK-cell lymphomas that characteristically present in the skin or subcutaneous tissue. However, WHO is not an organ-based classification and some categories (eg follicular B-cell lymphoma and peripheral T-cell lymphoma) include both cutaneous and systemic diseases, and these may have very different prognoses. It is, therefore, important that cancer registries are capable of recording sites of involvement for both B- and T-cell lymphomas so that the incidence and prognosis of cutaneous lymphomas can be established from national data sets in future years.

Abstract
BACKGROUND Primary cutaneous marginal zone B-cell lymphoma (MZCL) has recently been described. Differentiation from follicular centre cell lymphomas and lymphocytomas is often difficult due to insufficient experience and a lack of large series of patients. OBJECTIVES To characterize primary cutaneous MZCL better, we report clinical, histopathological, immunophenotypic and molecular genetics features in a series of 22 patients. METHODS All patients were treated and followed up at the same institution. Diagnosis of MZCL was based on the World Health Organization classification criteria. All samples were routinely tested with a wide panel of monoclonal antibodies. DNA was extracted from every sample following standard methods. IgH rearrangement and t(14;18)(q32;q21) studies were performed in all samples. RESULTS Twenty-two patients (20 men, two women; mean age 50 years, range 24-77) were included. The mean follow-up was 43 months. Seventy per cent of patients presented with characteristic skin lesions on the trunk or extremities, consisting of deep red to violaceous infiltrated plaques, nodules or tumours frequently surrounded by diffuse or annular erythema. Four patients presented with lesions on the head and neck area. Two patients had disseminated skin lesions. The main histopathological features were non-epidermotropic, dense lymphocytic infiltrates mainly distributed in a nodular pattern. Adnexal involvement was usually present, with eventual formation of lymphoepithelial complexes. Cytologically, the infiltrate was polymorphous with marginal zone B cells and B-monocytoid cells. Blastoid CD30+ cells were often observed. Colonized reactive germinal centres and lymphoplasmocytoid differentiation were frequently present. Neoplastic cells were CD20+, CD79a+, CD5- and CD10-. Monotypic expression of light chains was observed in 18 cases (13 kappa; five lambda). Clonal IgH rearrangements were detected in 14 cases. The bcl-2 mutation t(14;18)(q32;q21) was demonstrated in two cases. Most patients were treated with local radiotherapy. Complete response rate with this approach was 100%. Six patients (27%) had skin recurrences from 6 months to 8 years after first treatment. Five patients (23%) had extracutaneous involvement. Two of them had a large cell transformation and one died of lymphoma. Three of four patients with head and neck presentation developed extracutaneous disease. CONCLUSIONS MZCL appears to be a well recognizable entity, clinically, histologically and immunophenotypically. Although prognosis is generally good, the disease has potential for skin as well as extracutaneous recurrences. Large cell transformation and head and neck presentation may be associated with a worse prognosis.
