Abstract
Large multilobated nuclei lymphoma is a rare entity that is characterized morphologically by large neoplastic elements with prominent nuclear lobations and clinically by a predilection for extranodal sites and a favorable prognosis. According to the data collected to date, the neoplasia is thought to be of T-cell origin. The authors describe the clinical, morphologic and immunohistochemical findings of a case of non-Hodgkin's lymphoma with large multilobated nuclei that showed a definite B-lymphocyte origin.

Abstract
PURPOSE Primary mediastinal large cell lymphoma PMLCL is a recently described entity which has provoked considerable interest lately. The unique immunophenotype of the malignant cell, as well as conflicting reports regarding its response to therapy, prompted us to review the current literature focusing on the pathological and clinical aspects of this disease. DESIGN We reviewed the current literature that contained details on the clinical presentation, pathological profile and clinical outcome. RESULTS Most reports agree that PMLCL typically affects a young female population and presents with symptoms related to compression of mediastinal structures. Pathologically, the malignant cells may arise from a distinctive thymic medullary B cell subpopulation which is characterized by the following phenotype: CD19+, CD21-, CD20+, CD22+. Alterations of c-myc and lack of expression of HLA class 1 antigens on the tumour cell surface have been described. Response to treatment and clinical outcome have varied from one series to another and is possibly explained by the small number of patients in most series and by the heterogeneity of therapy. In general, the outcome does not appear to be worse than that of other large cell lymphomas although, given the young age of these patients, it might be expected to be more favourable. CONCLUSIONS Primary mediastinal large cell lymphoma is a distinct clinico-pathological entity characterized by: (1) a predominance of young adults; (2) female predominance (female/male ratio of 2:1) in contrast to the other large cell lymphomas; (3) CD19+/CD21- immunophenotype; (4) absence of HLA-class 1 antigen expression; (5) possible involvement of c-myc; (6) frequent dissemination at relapse to unusual anatomic sites in a pattern reminiscent of Burkitt's lymphoma. The role of radiotherapy and the optimal treatment for this disorder are issues that remain unresolved.

Abstract
Large multilobated cell lymphomas represent an heterogenous group comprising both B-cell and T-cell subtypes. The correct lineage identification of each subtype cannot be based on morphologic grounds, as it has already been stressed by other authors, and demands the use of immunophenotyping methods. In this study we review the literature and present eight new cases of large multilobated B-cell lymphoma which have been immunophenotyped in paraffin sections with a panel of monoclonal [L26 (CD20), 4KB5 (CD45R), UCHL1 (CD45RO), MT1 (CD43)] and polyclonal (anti-CD3, anti-kappa, anti-lambda) antibodies. We further investigated the expression of c-myc p62 oncoprotein and of proliferating cell nuclear antigen (PCNA) using the monoclonal antibodies c-myc 1-9E10 and PC-10 respectively. In all cases the neoplastic cells were positive for L26 (CD20) and negative for anti-CD3. Five cases were positive for 4KB5 (CD45R) while six cases stained positively for UCHL1 (CD45RO) or MT1 (CD43). Four cases were monoclonal in respect to light chain restriction. Immunoreactivity with c-myc 1-9E10 and PC-10 was observed in all cases. As far as c-myc 1-9E10 is concerned, positive cells constituted more than 45% of the neoplastic population in six cases, whereas in all cases the percentage of PC-10 positive cells was greater than 45%. The staining pattern was nuclear and/or cytoplasmic for c-myc 1-9E10 but solely nuclear for PC-10. The elevated c-myc and PCNA expression are indices of high proliferation rate in this type of lymphoma and may suggest a high malignancy grade.

Abstract
Multi-lobed non-Hodgkin's lymphoma (NHL) has recently been recognized as a NHL variant. A patient presented with a scalp nodule which, upon skull X-Ray, was seen to be associated with a bone defect. Immunophenotyping clearly demonstrated that this was a B-cell proliferation. Histologically the B-lymphocytes were closely related to centroblasts. There were no other extra cutaneous localizations. The present report emphasizes the importance of this clinico anatomical entity which shows prominent extra-nodal involvement, large lymphoid cells with multi-lobed nuclei and a good response to chemotherapy. Multi-lobed NHL may be a T-cell lymphoma, or a B-cell lymphoma closely related to centroblastic NHL. Although multi-lobed lymphomas have a predilection for cutaneous localizations, our case is the first primary cutaneous multi-lobed B-NHL, proven by immunophenotyping.

Abstract
Sixteen cases of primary anterior mediastinal B-cell lymphoma were characterized by morphologic, immunophenotypic, and clinical profiles. Twelve were men and four were women. The median age was 42 years. Virtually all tumors were of large cell type. Three main morphologic categories were identified, with one rare exception. In some tumors, the cells were compatible with centrocytes and centroblasts (four). Others had cells readily identifiable as centroblasts (six). Both these groups had a variable proportion of cells with multilobed nuclei. A third group was composed mainly of unclassifiable cells with multilobed nuclei (five). All had discernible sclerosis of varying intensity. A wider range of morphologic features and different sex distribution was noticed in comparison with previously reported clear cell features and younger women. The dominant phenotype of these B-cell lymphomas was CD19+, CD22+, CD37+, CD21-, CD30-, CD10-, CD5-, and Ig-negative. The finding of CD21-, Ig-negative phenotype, as observed by the authors and others, overlaps with some high-grade lymphomas of follicular center cell origin but is thought to bear similarity to a noncirculating population of thymic medullary B-cells. The tumors attained large size without peripheral dissemination and responded to chemotherapy as well as radiotherapy.

Abstract
Multilobated lymphomas were originally described as T-cell neoplasms, but many of B-cell type have subsequently been reported. A case of B-cell origin is reported in which both immunophenotypic and genotypic studies performed on a cell suspension of the lymphoma gave inconclusive and potentially misleading information, while paraffin and frozen section immunohistologic studies, as well as genotypic studies performed on DNA obtained from snap-frozen tissue, were definitive. Thus, this case illustrates some of the problems that may be encountered using cell suspensions as a source for immunophenotypic, and even the much more sensitive genotypic, studies.

Abstract
The classification of non-Hodgkin's lymphomas (NHLs) has been traditionally based on analysis of histologic sections and has been supplemented more recently by immunologic marker studies. It was the purpose of the present study to illustrate, side-by-side, sections and Romanowsky-stained imprints from the same surgical specimen from practically all categories of immunophenotyped NHLs, including rare and atypical variants that were difficult to classify from the histologic sections alone. Our results indicate that imprint cytology may reveal nuclear and cytoplasmic details not discernible in even the best tissue sections and that it may be selectively helpful in contributing to the classification of NHLs. Our results also show that the relative value of imprint cytology in the classification of malignant lymphomas varies greatly among categories. Specifically, we have found that imprints assist in three ways: the recognition of plasmacytoid features in small cell lymphocytic lymphomas, the recognition of plasmacytoid immunoblastic lymphoma, and the differentiation between NHLs which may be difficult to distinguish histologically. These include (1) small lymphocytic lymphoma versus lymphocytic lymphoma of intermediate differentiation, (2) true histiocytic malignancies versus large cell malignant lymphomas with abundant cytoplasm and/or phagocytosis, (3) anaplastic myeloma versus plasmacytoid immunoblastic lymphoma, (4) large noncleaved versus plasmacytoid immunoblastic lymphoma, (5) lymphoblastic lymphoma versus diffuse small cleaved cell lymphoma, and (6) lymphoblastic lymphoma versus small noncleaved cell lymphoma. Lymph node imprints are easy to prepare and readily interpretable by those experienced in the study of abnormal blood and bone marrow films. Their value as an ancillary methodology aimed at optimal accuracy in the classification of NHLs should be recognized.

Abstract
Circulating cerebriform lymphoid cells (Sezary cells) are considered to be highly predictive of cutaneous T-cell Lymphoma (CTCL). A leukemic peripheral blood (leukocyte count 24.5 x 10(9)/l) composed predominantly of cerebriform cells was found in a 75-year-old man presenting with weight loss and generalized lymphadenopathy but without skin lesions. Cell suspensions studies and immunohistochemistry of peripheral blood revealed that the cerebriform cells were B-cells (IgM+ Kappa+, HLA DR+, Leu 1+, CALLA-, B1+, and OKT 10+). A variety of T-cell markers (other than Leu1) was negative. Computer-assisted morphometry confirmed a nuclear profile typical of CTCL (mean nuclear contour index, 7.47). A lymph node that underwent subsequent biopsy revealed a follicular malignant lymphoma of small to intermediate cells with similar morphologic and immunologic characteristics to the circulating cerebriform cells. The findings of a leukemic presentation of a cerebriform B-cell lymphoma extends the recent observation of nodal B-cell lymphomas composed of cerebriform cells and indicates that circulating cerebriform cells should not be considered to be exclusively of T-cell origin.

Abstract
Multilobated non-Hodgkin's lymphomas (NHL) have recently been recognized as an NHL variant. During a period of 10 years we observed 30 individuals with NHL in which more than 30% of the malignant cells had a characteristic multilobation. The immunologic phenotype was determined in 14 of these cases. One was of T-cell lineage, and the others exhibited B-lymphoid markers. Sixty-eight percent of the patients presented with extranodal localizations. In the clinical follow-up a complete remission was observed in 78% of patients with a mean duration of 37 months (range, 5 to 120 months). The actuarial survival after 5 years was 45%. From these data we conclude that multilobated NHL are comparable to diffuse, large cleaved-cell NHL of an intermediate grade malignancy according to the Working Formulation or are comparable to the diffuse centrocytic-centroblastic NHL according to the Kiel classification. The neoplastic cells are to be considered as variants of follicle center cells, but the clinicopathologic correlation indicates that multilobated NHL represent a distinct nosologic entity.

Abstract
Ten cases of non-Hodgkin's lymphomas, mainly composed of large multilobated cells, have been studied. Our results are consistent with the view that they represent a somewhat heterogeneous group of lymphoid tumours displaying different morphological, clinical and immunophenotypic features. In B-cell type the large multilobated cells were histologically characterized by prominent nucleoli and distinctly basophilic cytoplasm whereas in the T-cell type they had indistinct or small nucleoli and ill-defined weakly eosinophilic cytoplasm. These differential features between B- and T-cell type were confirmed by electron microscopy. From a clinical standpoint B-cell type was characterized by a constant involvement of lymphoid tissues (lymph nodes and/or Waldeyer's ring); T-cell type showed, on the contrary, a more frequent involvement of extra-lymphoid sites (mainly bone and subcutaneous tissues). Our study provides some morphological features that may be helpful for a correct differential diagnosis in this heterogeneous group of non-Hodgkin's lymphomas.

Abstract
The clinical, pathologic, and immunologic features in nine cases of non-Hodgkin's lymphoma of the multilobated B-cell type are described. Clinical and phenotypic heterogeneity was observed in these B-cell neoplasms. A probable follicular center cell derivation for these cytologically unusual B-cell lymphomas is supported by antecedent histories of follicular center cell neoplasms in three cases; a focal nodular pattern in one case; the demonstration of peanut lectin (PNA) receptors, a marker for follicular center cells, on neoplastic multilobated B cells; and immunoultrastructural studies of nonneoplastic tonsillar cells that identified and characterized rare multilobated cells, immunoreactive for B1, B2, and Ia membrane antigens, a phenotype consistent with follicular center-type cells. Comparison of B- and T-cell multilobated lymphomas revealed that only immunologic studies accurately discriminated between these neoplasms.

Abstract
Four cases of multilobated B-cell lymphoma, one follicular and three diffuse, are described. Many of the lymphoma cells show marked lobulation of the nuclei, and possess multiple prominent nucleoli. There are admixed classical centrocytes, classical centroblasts, and cells with morphology intermediate between classical centroblasts and multilobated cells. Multilobated cells are also observed in small numbers in germinal centres of lymph nodes showing reactive follicular hyperplasia. We believe that the multilobated B-cell may represent one form of centroblast during transition between the centroblastic and centrocytic stages. Multilobated B-cell lymphoma may be its neoplastic counterpart in which the nuclear lobulation is further exaggerated.

Abstract
We analyzed the clinicopathologic features of 13 patients with immunologically confirmed peripheral T-cell lymphoma. The lymphomas were classified into poorly differentiated lymphocytic, mixed cell, and large cell types. Marked morphologic heterogeneity was noted within the mixed cell and large cell categories, and the various subtypes are described. Twelve of the 13 patients received multiagent chemotherapy. Only three of the nine patients with poorly differentiated or mixed cell lymphomas achieved a complete remission, and the median survival for this group was 11 months. In contrast, all three of the treated patients with large cell lymphomas achieved a complete remission, two of whom are alive without disease (14 and 29 months, respectively). Classification of peripheral T-cell lymphomas into lymphocytic, mixed cell, and large cell types, as well as further subclassification within the heterogeneous groups, is suggested so that pathologic features of prognostic significance can be identified.

Abstract
Seven cases of B-cell lymphoma that morphologically resembled T-cell lymphoma are described. These cases are of four morphologic types: atypical poorly differentiated lymphocytic lymphoma (PDLL) with convoluted nuclei, "Lennert's" lymphoma, mixed lymphocytic-"histiocytic" lymphoma with large variation in size of abnormal cells, and "histiocytic" lymphoma with large multilobed nuclei. These cases add further support to the belief that morphologic criteria alone are not sufficient for accurate immunologic classification of the malignant lymphomas since they may represent a distinct clinicopathologic entity.

Abstract
Malignant lymphomas with multilobated nuclei are rare, recently recognized neoplasms of the immune system initially thought to be of T-cell type. Reported is a case of large cell lymphoma with multilobated nuclei in which immunologic marker studies demonstrated that the neoplastic cells had characteristics of B-lymphocytes. The neoplastic cells possessed surface and cytoplasmic immunoglobulin of the IgG, lambda type, and stained diffusely with monoclonal antibodies to B1, Leu-10 and OKIaI antigens and focally with anti-B2. The lymphoma cells did not react with monoclonal antibodies directed against T-cells and monocytes/granulocytes. As documented here with multiple monoclonal antibody lymphocyte markers, the multilobated lymphoma can have a B-cell phenotype as well as the cell phenotype described previously. Thus, even the unique finding of multilobated nuclear morphologic features is unreliable in predicting the lymphocyte lineage.

Abstract
Three cases of primary malignant lymphoma of the maxilla are reported. The primary intraosseous origin of these tumors was demonstrated by x-ray examination and surgical exploration. The initial interpretation as odontogenic infection led to a delay in starting therapy of 9 months in one case. Biopsies of two cases were initially interpreted as sarcoma because of a dense reactive fibrosis between the tumor cells. Subsequently, hemimaxillectomy was performed in one case. Histologically and ultrastructurally the tumor cells showed marked nuclear abnormalities with cleavage, folding, and lobulation. Immunohistochemical studies of two cases showed a monoclonal immunoglobulin expression, IgG-K; T-lymphocyte-associated antigens were not detected on the tumor cells. The findings indicate the existence of a primary B-cell malignant lymphoma of bone with multilobated nuclei. The lymphoid nature may be masked by a dense proliferation of connective tissue. The relation of these tumors to the classifications for malignant lymphoma of lymph node is discussed.

Abstract
Paraffin sections of surgical and autopsy material from 12 cases of primary non-Hodgkin's lymphomas of the central nervous system were examined for histopathological diagnosis and for the demonstration of cytoplasmic immunoglobulins. According to the Kiel classification, there were five cases of lymphoplasmacytoid polymorphous lymphoma, five of immunoblastic lymphoma, one of lymphoblastic lymphoma of convoluted cell type. There was also one of the recently described multilobated lymphoma. An immunohistological study of light and heavy chains by peroxidase-antiperoxidase (PAP) technique and avidin-biotin complex (ABC)technique was performed. Intracellular immunoglobulins were demonstrated in seven cases: four cases were classified as immunoblastic lymphomas and three cases as lymphoplasmacytoid lymphomas. Negative immunoglobulin staining was observed in five cases: two lymphoplasmacytoid lymphomas, one immunoblastic, one lymphoblastic of convoluted cell type and one multilobated. A 'monoclonal' pattern of immunoglobulin staining was detected in six cases. One case, classified as immunoblastic lymphoma, showed 'bitypic' staining for kappa and lambda chains. It was concluded that primary CNS non-Hodgkin's lymphomas of the present series showed morphological and immunohistological features similar to those of malignant lymphomas arising in extraneural sites. In particular, the presence in our series of a multilobated lymphoma, as a primary CNS tumour, is emphasized.

Abstract
Caribbean T-cell lymphoma/leukemia (CATL) is a recently described neoplasm similar to Japanese adult T-cell leukemia/lymphoma, but it occurs in patients born in a different geographic region. Four adult Black West Indian women with CATL were studied using a multiparameter approach, including clinical, hematologic, pathologic, and immunologic investigations. The disease was usually characterized by adenopathy (with or without hepatosplenomegaly), peripheral blood involvement, hypercalcemia often in the absence of gross bony lesions, and a poor prognosis. The neoplastic cells were pleomorphic with marked nuclear irregularity of a multilobated or more cerebriform type. Lymph node biopsies demonstrated a diffuse pleomorphic lymphoma with variable degrees of nuclear irregularity and transformation. Marrow involvement consisted of focal nodules or, more commonly, scattered atypical lymphoid cells. Marrow biopsies also often demonstrated osteoclastic activity. Cases were all of T-cell origin, most commonly of T-helper phenotype, although there was some phenotypic heterogeneity. All patients had antibodies to the human T-lymphoma/leukemia virus.

Abstract
A 59-year-old man was hospitalized for evaluation of cervical lymph node enlargement, and a diagnosis of a diffuse histiocytic lymphoma with B-cell markers was made. The unusual multilobated nature of the lymphoma cells is the subject of this study. The light and electron microscopic features are described and compared with those previously reported T-cell lymphomas which appear to have similar morphologic features. The importance of performing immunologic marker assays to determine T-cell or B-cell type and the limited predictive value of morphologic features in this regard are emphasized.

Abstract
Tissue from 53 non-Hodgkin's lymphomas of high-grade malignancy according to the Kiel classification were analysed for cellular immunological markers. In most cases studies were performed in parallel on cell suspensions and cryostat sections. Histologically, the lymphomas were classified as anaplastic centrocytic (four), centroblastic (seven), Burkitt type (three), convoluted-cell type (five) lymphoblastic-unclassified (10), immunoblastic (IBL) (19) and pleomorphic T-cell type (five). Immunological phenotyping resulted in 60% B lymphomas characterized by monotypic surface membrane Ig (SmIg) and/or cytoplasmic Ig (CIg), and 23% T lymphomas with detectable E receptors; 17% of cases were non-expressive (O-type). Unusual SmIg-types were noticed in some monoclonal proliferations. Gamma (gamma) and mu chains occurred simultaneously in four cases; delta chain was the only heavy-chain in one case and a heavy-chain was absent in one case. Cases of IBL were of T-cell type in two cases, and two other cases were non-expressive. The cases of B-IBL expressed CIg in 93%, but the B lymphomas other than B-IBL only in 38%. Receptors for Fc-IgG and C3 were expressed by all major immune phenotypes (B, T, O), but were infrequent in lymphoblastic lymphoma unclassified (O-type). Adoption of immunological techniques to include frozen tissue studies was necessary in order to reach a conclusion regarding the immune phenotype in several cases.
