Ki-1-positive large cell anaplastic lymphoma (Ki-1 LCAL) is recognized as a clinicopathologic syndrome with fever, peripheral lymphadenopathy and cutaneous nodules; the neoplastic cells express Hodgkin's disease-associated antigen, Ki-1 (CD30). We review here a recent case of Ki-1 LCAL with multiple bone lesions with destruction and present additional information. Although bone absorption is reported in some cases of Ki-1 LCAL, the genesis of bone absorption is unclear. Interleukin-6 (IL-6) is an important regulator of osteoclast formation and activation and can induce bone absorption. In our case, the surgically removed tumor tissue was studied for IL-6 mRNA expression and IL-6 secretion without any stimulation. Northern blot analysis showed strong IL-6 mRNA expression in the tumor tissue and ELISA assay showed a large amount of IL-6 in culture supernatants of the tumor tissue. Based on these results, coupled with the reported evidence, we discuss the close relationship between the presence of osteolytic lesions and IL-6 production in Ki-1 LCAL.

The expression of sialosylated Lewis chi (SLEX), a ligand for endothelial leukocyte adhesion molecule 1 in malignant lymphomas, was immunohistochemically examined, using the monoclonal antibody, CSLEX1, which specifically reacts with SLEX. It was expressed in 6 out of 64 non-Hodgkin's lymphomas, which consisted of 1 nasal large-cell lymphoma and 5 of 8 (62%) Ki-1-positive anaplastic large-cell lymphomas (ALCL). One nasal lymphoma positive for SLEX co-expressed a T cell marker, cluster of differentiation (CD) 5, and natural killer (NK) cell markers such as CD56 and CD16, indicating that SLEX+ nasal lymphoma cells are possibly malignant counterparts of SLEX+ NK cells. SLEX did not react with 30 B cell lymphomas or most Hodgkin's disease lymphomas, though it did with one lymphocyte predominance type. Although SLEX+ ALCL exhibit T cell markers in some cases, some ALCL expressing SLEX may represent histiocytic differentiation of the neoplastic cells. The lymphoma cells of ALCL were preferentially positive for SLEX, in contrast to Hodgkin's disease cells, and thus CSLEX1 in conjunction with CD30 and CD15 should be of use for analyzing and making differential diagnoses of routine paraffin-embedded sections of ALCL.

Non-Hodgkin's lymphomas (NHL) are part of an overlapping spectrum of lympho-proliferative diseases in childhood. In the first of this 2 part series, the clinicopathological aspects of NHL in childhood are discussed. The rapid progression of disease, the high incidence of micrometastases (over 80%) at diagnosis, and the propensity of hematogenous spread to the bone marrow and the central nervous system (CNS) as well as the clinico-pathologic 'clusters' associated with particular presenting sites distinguish the pediatric forms of disease. Abdominal primary sites most frequently manifest diffuse undifferentiated (Burkitt's or non-Burkitt's) histopathology, B-cell immunophenotype, FAB-L3 cytomorphology and specific karyotypic and/or genotypic alterations of the immuno-globulin genes and the c-myc oncogene. Mediastinal presentation is associated with lymphoblastic histopathology, T-cell immunophenotype and a variety of less consistent karyotypic and genotypic aberrations. Ki-1 lymphoma, a rare subtype of large cell NHL with specific features is often of T cell origin. The requirements for diagnosis, staging and monitoring are presented in the context of the associations between clinico-pathological presentation and subsequent behavior. The most frequent sites of disease progression and relapse are involvement of the bone marrow and the CNS. For Burkitt's lymphoma there is a historic perspective and a description of particular epidemiologic, clinical, virologic, immunophenotypic and genotypic features. Cytogenetic and molecular biologic studies of genomic rearrangements are advancing the understanding of oncogenesis, clonality, lineage, and clinical behavior. The capacity to detect and amplify DNA from submicroscopic disease may contribute to prognostic stratification both at diagnosis and during subsequent monitoring.

In this study, the expression of the novel intermediate filament protein Restin in human tissues was analyzed. Restin expression was studied by immunohistochemistry using polyclonal and monoclonal antibodies. Restin was not detected in normal tissues, a range of B- and T-cell non-Hodgkin's lymphomas, and nonlymphoid tumors. However, Restin was present in Reed-Sternberg cells and variants thereof in Hodgkin's disease, with the exception of the lymphocyte-predominant, paragranuloma subtype. Restin was also highly expressed in anaplastic large-cell lymphoma (so-called Ki-1 lymphoma). As expected, Restin was also expressed in Hodgkin cell lines L428, L428KSA, Co, and KM-H2 and the anaplastic large-cell lymphoma cell line Karpas 299, which was confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blotting, as well as Northern blotting. The presence of Restin in both Hodgkin's disease and anaplastic large-cell lymphoma is intriguing and might indicate a role of this structural protein in the pathogenesis of both conditions.

A 45-year old immunocompetent man presented with multiple lesions in the brain. A histological examination of the tumors showed a diffuse infiltrate of lymphoid cells with cellular polymorphism and of multinucleated giant cells. These cells were immunolabeled with antibodies against B cell lineage and with a monoclonal antibody, Ber-H2 (CD30), which showed the presence of Ki-1 antigen. Recently, among systemic non-Hodgkin's lymphomas, attention has been given to Ki-1-positive lymphomas, which have been incorporated in the up-dated Kiel classification. We report here a case of Ki-1-positive lymphoma arising in the CNS and review previously reported cases.

In this session there seemed to be general agreement on the existence of anaplastic large cell lymphoma (ALCL) as an entity defined by a characteristic morphology and by diffuse expression of the Ki-1 (CD30) antigen. The discussion indicated the lack of specific immunophenotypic and genotypic markers for such a neoplasm and the variability of the clinical patterns associated with it: these include a childhood form, an adult cutaneous form, and an adult nodal disease. While typical cases of ALCL are clearly distinct (by pathologic, cytogenetic, and clinical criteria) from Hodgkin's disease (HD), there is a variety of histologic and immunophenotypic patterns that overlap those of ALCL and HD; most of these would be classified as HD, lymphocyte depletion (LD) or nodular sclerosis (NS), syncytial subtype. No agreed-upon criteria were found that could consistently define these patterns, nor was an agreement possible on whether they are part of a continuum unifying ALCL and HD or phenotypically similar expressions of different diseases.

The cytopathologic, immunohistochemical and ultrastructural features of a case of Ki-1-positive lymphoma are presented and discussed. On fine needle aspiration (FNA) biopsy smears, the Ki-1-positive lymphoma was characterized by large isolated cells with abundant dense/vacuolated cytoplasm and large nuclei with irregular profiles. Although most cells contained one nucleus, binucleated and multilobed/multinucleated cells were also seen. The cohesion of the malignant cells in histologic sections of a biopsied lymph node suggested an anaplastic carcinoma. The discrepancy was resolved by ultrastructural and immunologic analyses. The main differential diagnoses on FNA material include Hodgkin's disease, malignant melanoma and undifferentiated carcinoma; the cytologic suspicion should be confirmed by immunocytochemical studies.

The case is described of a 62-year-old man with a 10-year history of hairy cell leukemia (HCL) who subsequently had a large-cell anaplastic or so-called Ki-1-positive lymphoma. Immunocytochemical staining of the lymphomatous node revealed positivity for Ki-1 (CD30) and epithelial membrane antigen in the tumor cells, and flow cytometric analysis showed simultaneous expression of Leu M5 (CD11c) and Leu 14 (CD22). Although HCL has been reported to coexist with both Hodgkin's disease and non-Hodgkin's lymphoma, the authors believe this is the first case in which a Ki-1-positive lymphoma developed in a patient with HCL. The clinicopathologic and immunologic features of both entities are discussed, as is the association of HCL with other neoplasms.

Non-Hodgkin's lymphomas (NHL) are part of the spectrum of disease associated with HIV infection. However, there are only occasional reports of NHL of T-cell origin in HIV-infected patients. A previously asymptomatic HIV-infected man, who was seronegative for human T-lymphotropic virus type I antibodies, developed a high-grade peripheral T-cell lymphoma of anaplastic large-cell type which was Ki-1 + (CD30 +), HLA-DR+, epithelial membrane antigen +, CD25 +, CD71 +, CD2 + and CD5 +. Pan-B markers CD19 and CD22 and histiocytic marker CD68 were negative. At diagnosis the patient had 0.3 x 10(9)/l T-helper lymphocytes. The response to chemotherapy was dramatic and the patient is alive and disease-free 18 months after treatment. A review of previously described peripheral T-cell lymphomas in HIV-positive individuals is performed, and we conclude that the spectrum of neoplasms in such cases is probably broader than originally thought.

The authors retrospectively reviewed the clinicopathologic and immunologic features of 65 consecutive cases of childhood lymphoma reported between 1980 and 1989. Southern blot hybridization was also performed in 23 cases to study their association with Epstein-Barr virus (EBV) and human T-cell leukemia virus type 1 (HTLV-1). The 65 cases included 56 non-Hodgkin's lymphoma (NHL) (86%) and 9 Hodgkin's disease (HD) (14%). The NHL could be classified into the following groups: Group I, small noncleaved cell lymphoma (20 cases); Group II, lymphoblastic lymphoma (17 cases); Group III, large cell lymphoma (17 cases); and miscellaneous (2 cases). There was no follicular lymphoma case. Immunohistochemical study on paraffin sections and/or frozen specimens in 47 cases of NHL showed that all the Group I cases belonged to B-cell neoplasm (17 of 17 cases); most of the Group II cases belonged to T-cell neoplasm (9 of 14 cases); and most of the Group III cases were peripheral T-cell lymphoma (PTL) (8 of 16 cases), including 2 cases of Ki-1 lymphoma. The majority of childhood NHL belonged to high-grade malignancy with an aggressive clinical course (median survival time, 8 months). The EBV DNA could be detected from the tumor tissues in 4 of 6 PTL, but in none of the remaining 19 cases of NHL including 6 Burkitt's type lymphomas. HTLV-1 proviral genome was not detected in all specimens examined. The authors concluded that the distribution pattern and clinicopathologic feature of childhood lymphoma in Taiwan are comparable to that in Japan and western countries. The frequent association of EBV with aggressive PTL was unique and deserves additional investigation.
