Background: The role of (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET) in the evaluation of anaplastic large-cell lymphoma (ALCL) first presenting in the skin is not well established, while computed tomography (CT) is used as a standard procedure.

Objectives: The aim of this study was to evaluate the use of FDG-PET versus CT at initial staging of ALCL first presenting in the skin.

Materials & Methods: Eleven cases of ALCL first presenting in the skin who underwent both FDG-PET and CT were retrospectively analysed. Read More

Therapeutic agents designed to stimulate the immune system are now cornerstones in the treatment of metastatic melanoma. These drugs promote lymphocyte growth and survival, which could plausibly result in clinical lymphoproliferative disorders. We report the case of a 62-year-old female with metastatic melanoma who developed primary cutaneous small/medium CD4 T-cell lymphoproliferative disorder (PC-SMTCL) after treatment with vemurafenib and recombinant high-dose interleukin-2 (IL-2).

Background: Anaplastic large cell lymphoma (ALCL) is the second most common T cell lymphoma and 2% of all non-hodgkin lymphoma (NHL). It is an aggressive lymphoma with three subtypes, primary cutaneous ALCL, primary systemic ALK +ve ALCL and primary systemic ALK-ve ALCL depending upon rearrangement of Anaplastic Lymphoma Kinase (ALK) gene into ALK +ve and ALK -ve ALCL. Purpose of study is to determine the outcome of patients with ALCL treated at our institute. Read More

CD28 is the major costimulatory receptor on T cells regulating proliferation, survival and effector function. Acquired mutations in the extracellular domain of CD28 have been identified in patients with cutaneous T cell lymphoma, angioimmunoblastic T cell lymphoma and other T cell neoplasms, suggesting it may contribute to disease pathogenesis. We used a heterologous system in which mutant human CD28 was expressed on primary murine T cells deficient in CD28 to ascertain how specific mutations identified in a genetic screen of patients with cutaneous T cell lymphoma affected normal T cell function.

SAHA (vorinostat) is a histone deacetylase inhibitor approved by the USA Food and Drug Administration (FDA) for treating advanced refractory cutaneous T cell lymphomas. As SAHA alters the expression of many genes under control of the Sp1 transcription factor, we examined the effect of its association with the FDA-approved anticancer antibiotic Mithramycin A (MTR, plicamycin), a competitive inhibitor of Sp1 binding to DNA. Sézary syndrome (SS) cells, expanded ex vivo from peripheral blood mononuclear cells of 4 patients, were tested for their sensitivity to the drugs regarding cytotoxicity and differential responsive gene expression.

It is also the only bicyclic inhibitor to undergo clinical assessment and is considered a promising drug for the treatment of T-cell lymphomas. The cellular action of romidepsin results in enhanced histone acetylation, as well as the acetylation of other nuclear or cytoplasmic proteins, influencing cell cycle, apoptosis, and angiogenesis.
