CD30 is a transmembrane glycoprotein of tumor necrosis factor receptor family, which is expressed differently in various lymphomas. It has specific effects on the proliferation and function of tumor cells. However, the significance of CD30 expression has not been fully recognized by clinicians and pathologists, and the detection and evaluation of CD30 have not been standardized. The role of CD30 in the diagnosis of lymphoma, detection methods and reporting standards are summarized in the paper to improve the understanding of CD30.

Primary cutaneous anaplastic large cell lymphoma is a rare non-Hodgkin's lymphoma.The tumor cells have the characteristics of anaplastic cells,expressing CD30 but not anaplastic lymphoma kinase.In this study,we reported a case of primary cutaneous anaplastic large cell lymphoma in a Tibetan child and summarized the clinicopathological features,aiming to strengthen the understanding of this disease.

PURPOSE: Caveolin-1 is proposed to represent a novel tumor suppressor protein and expression of recombinant caveolin-1 is sufficient to restrict the growth potential of transformed cells isolated from primary tumors of the breast, lung, and ovaries. We examined the relationship of caveolin-1 and Ki-67 expression to clinicopathological variables in patients with clear cell carcinomas of the kidney. MATERIALS AND METHODS: We examined caveolin-1 and Ki-67 expression in 119 clear cell carcinomas of the kidney using immunohistochemistry, and analyzed its relationship with tumor size, nuclear grade, TNM stage, vascular invasion, capsular invasion, metastasis, and metachronous metastasis were investigated. RESULTS: Of the 119 tumors analyzed, lymph node and distant metastasis (synchronous metastasis: 7, metachronous metastasis: 15) occurred in 3 and 22 cases, respectively. Caveolin-1 expression correlated with the T stage(p=0.004), TNM stage(p=0.013), metastasis(p=0.013), and metachronous metastasis(p=0.001). Ki-67 expression correlated with the T stage(p=0.041), nuclear grade(p=0.011), and vascular invasion(p=0.043). Caveolin-1 and Ki-67 expression showed similar changes, but there was no statistical significance(p=0.050). CONCLUSIONS: Caveolin-1 is expressed frequently in patients with metachronous metastasis, and may predict metastasis after surgery for clear cell carcinoma of the kidney.

Lymphomatoid papulosis(LyP) is a chronic recurrent dermatosi characterized by involuting and recurring papules, plaques, and nodules showing histologic feaurs suggesting rnalignant lymphoma. On histologic ground, it is divided into two types. type A and type B. In type A, large atypical lymphocytes are the main cellular cornponent and most of these express CD 30(Ki-1) antigen, which has been p!reviously thought to be specific for Read Sternberg cells of Hodgkins disease. In type B, cerebriform mononuclear lymphocytes sirr la to those in mycosis fungoides predominates. We report two cases of lymphomatoid papulosis, type A and type B, respectively. The large atypical cells in type A LyP expressed Ki 1 antigen. Both case were treated with PUVA and the outcome of the treatment has been fair.

OBJECTIVETo explore the clinicopathologic features of CD30-positive sinusoidal large B-cell lymphoma (CD30 + SLBCL) and its relative correlation with Epstein-Barr virus (EBV).

METHODSTwo cases of CD30 + SLBCL, a 65-year-old men and a 85-year-old women were morphologically and immunophenotypically analyzed. EBV status was also evaluated through not only the polymerase chain reaction (PCR) amplification to the EBV Bam HIW DNA sequence, but also an immunohistochemical detection of the latent membrane protein 1 (LMP1).

RESULTSThe patients presented with similarly superficial lymphadenopathy. One of them died of the tumor within 10 months. Microscopically, both of the neoplasms were characterized by a cohesive sinus growth pattern and the monomorphic cytology of the tumor cells. Immunohistochemically, They were both positive for CD45, CD30, and CD20 or CD79alpha, whereas neither expressed EMA, ALK1, nor any histiocytic/T-lineage markers. No evidence of EBV-infection could be found either.

CONCLUSIONSCD30 + SLBCL is a morphologically and immunophenotypically distinctive variant of diffuse large B-cell lymphoma, which should be distinguished from T/null cell type anaplastic large cell lymphoma and some other nodal lesions with a predominantly sinusoidal infiltrative pattern. CD30 + SLBCL may not be correlation with EBV.

OBJECTIVETo evaluate the expression and clinical significance of tumor necrosis factor receptor (TNFR) superfamily protein CD30 in diffuse large B cell lymhoma (DLBCL).

METHODSThe CD30 expression, clinical characteristics and prognosis of 63 patients with DLBCL, NOS out of 149 patients with DLBCL admitted in our hospital between January 2008 and December 2012 were analyzed retrospectively.

RESULTSno significant relationship existed between CD30 expression and clinical features, such as age, sex, B symptoms, staging, ECOG PS, LDH level, extranodal site involvement, IPI, GCB or non GCB type, bone marrow involvement. By univariate analysis, the clinical factors associated with general OS and EFS, included CD30, ECOG PS, B symptoms, extranodal site involvement, LDH level, IPI, bone marrow involvement and rituximab. Univariate analysis in GCB DLBCL indicated that CD30 had no significant effect on OS and EFS. However, univariate analysis in non-GCB DLBCL indicated CD30 was associated with longer OS (P=0.037) and showed a tendency of better EFS (P=0.067). In multivariate analysis, IPI and CD30 were independent prognostic factors for OS (IPI: P=0.000, 95%CI 0.042-0.374, CD30: P=0.044, 95%CI 1.055-60.613), and IPI also was independent prognostic factors for EFS (P=0.000, 95%CI 0.040-0.360). CD30+ and DLBCL have a tendency of better EFS (P=0.050, 95%CI 0.996-56.501).

CONCLUSIONCD30 expression level correlates with the prognosis of DLBCL and has a certain clinical value, which may be a new prognostic index of DLBCL.

OBJECTIVETo study the role of microRNAs (miRNAs) in ALK-negative anaplastic large cell lymphoma and CD30 positive peripheral T cell lymphoma (not otherwise specified), and discuss the pathogenesis of miRNAs in ALK-negative anaplastic large cell lymphoma.

METHODSThree cases of ALK-negative anaplastic large cell lymphoma of lymph node, 3 cases of CD30-positive peripheral T cell lymphoma (not otherwise specified) of lymph node and 3 cases of reactive hyperplasia of lymph node were detected by high flow microarray of miRNAs. The method of real-time quantitative polymerase chain reaction was further applied for 7 miRNAs in 15 cases of ALK-negatie anaplastic large cell lymphomas of lymph node and 15 cases of CD30-positive peripheral T cell lymphoma (not otherwise specified) of lymph node.

RESULTSThe significant difference of 13 miRNAs was found between ALK-negative anaplastic large cell lymphoma and CD30 positive peripheral T cell lymphoma (not otherwise specified) (P < 0.05), of which the result of 5 miRNAs was consistent with miRNAs expression spectrum: miR-664b-5p, miR-1275, miR-4739, miR-4736 and miR-504-5p, the difference was statistically significant (P < 0.05). Compared with reactive hyperplasia of lymph nodes, miR-664b-5p, miR-1275 and miR-4739 were significantly under-expressed (P = 0.004, P = 0.021, P = 0.031) and miR-4736 and miR-504-5p were significantly over-expressed (P = 0.009, P = 0.007) in ALK negative anaplastic large cell lymphoma.

CONCLUSIONSMiR-664b-5p, miR-1275, miR-4739, miR-4736 and miR-504-5p may become an important indicator in the differentiation ALK-negative anaplastic large cell lymphoma from CD30-positive peripheral T cell lymphoma (not otherwise specified). MiR-4739, miR-4736 and miR-1275 may play important role in pathogenesis of negative-anaplastic large cell lymphoma by target genes: TNFRSF8 and TMOD1.
