Mycosis fungoides (MF) is the most common form of cutaneous T-cell lymphoma. Although indolent in its early stages, MF is more aggressive in advanced stages, particularly if large cell transformation occurs. Histologically, transformed MF is similar to primary cutaneous anaplastic large cell lymphoma (pcALCL) and nodal ALCL (nALCL). MF had not been associated with immunohistochemical expression of anaplastic lymphoma kinase (ALK) until we previously reported a case documenting the presence of ALK by immunohistochemistry in a patient with stage IA MF and concurrent nALCL...

PKM2 (pyruvate kinase M2), a critical regulator of glycolysis, is phosphorylated by numerous growth factor receptors and oncogenic tyrosine kinases including NPM-ALK which is expressed in a subset of aggressive T-cell non-Hodgkin lymphomas known as anaplastic large cell lymphoma, ALK-positive. Our previous work demonstrated that phosphorylation of Y105-PKM2 by NPM-ALK regulates a major metabolic shift to promote lymphomagenesis. In addition to its role in metabolism, recent studies have shown that PKM2 promotes oncogenesis by phosphorylating nuclear STAT3 (signal transducer and activator of transcription 3) and regulating transcription of genes involved in cell survival and proliferation...

Breast implant-associated (BIA) anaplastic large-cell lymphoma (ALCL) is a rare disease, comprising a small percentage of all non-Hodgkin lymphomas (NHLs), reportedly 2-3%. There is currently no established standard approach to the treatment of BIA ALCL. The first case on the development of ALCL in the presence of a breast implant was reported in 1997 and the association was first identified by the Food and Drug Administration in 2011. We herein describe a case of BIA ALCL in a patient with a previous history of breast cancer and breast reconstruction who presented with hardening of her breast implant...

Indoleamine 2,3-deoxygenase 1 (IDO1) induces immune tolerance in the tumor microenvironment (TME) and is recognized as a potential therapeutic target. We studied the expression of both IDO1 and the related tryptophan 2,3-dioxygenase (TDO) in several different subtypes of cutaneous T-cell lymphoma (CTCL), and evaluated the kynurenine (KYN) pathway in the local TME and in patient sera. Specimens from the total of 90 CTCL patients, including mycosis fungoides (MF, n = 37), lymphomatoid papulosis (LyP, n = 36), primary cutaneous anaplastic large cell lymphoma (pcALCL, n = 4), subcutaneous panniculitis-like T-cell lymphoma (SPTCL n = 13), and 10 patients with inflammatory lichen ruber planus (LRP), were analyzed by immunohistochemistry (IHC), immunofluorescence (IF), quantitative PCR, and/or liquid chromatography-tandem mass spectrometry (LC-MS/MS)...

INTRODUCTION: Systemic ALK-positive anaplastic large cell lymphoma (ALK-positive ALCL) is a T-cell lymphoma. Owing to its rarity, variations in incidence and survival at the population level are not clearly known. MATERIALS AND METHODS: Using the Surveillance Epidemiology and End Results database (SEER 18), we selected patients aged ≥ 20 years with ALK-positive ALCL, diagnosed between 2001 and 2013. Incidence rate, overall survival (OS), and its determinants were analyzed with a significance level of P < ...

Anaplastic large cell lymphoma (ALCL) is a T-cell lymphoma which has been recognized to have a variable clinical presentation and a broad spectrum of histomorphologic features. Its variable histomorphologic appearances are sometimes diagnostically challenging for the pathologists since they can mimic sarcomas, melanomas and undifferentiated carcinomas. To our knowledge, a previous case of axillary soft-tissue mass of ALK-positive ALCL with an alveolar growth pattern has been so far reported in the literature...

Hitherto poor outcomes, paucity of data and heterogeneity in International approach to Pediatric NHL (Non-Hodgkin Lymphoma) prompted the need for guidelines for Indian population with vast variability in access, affordability and infrastructure across the country. These guidelines are based on consensus among the experts and best available evidence applicable to Indian setting. Evaluation of NHL should consist of easily doable and rapid tissue diagnosis (biopsy or flow cytometry of peripheral blood/malignant effusions), St Jude/IPNHLSS (International Pediatric Non-Hodgkin Lymphoma Staging System) and risk grouping with CSF (Cerebro-spinal fluid), bone marrow, whole body imaging [CECT (Contrast enhanced computerized tomography) ± MRI (Magnetic resonance imaging)] and blood investigations for LDH (Lactate dehydrogenase), TLS (Tumor lysis syndrome) and organ functions...

Background: Primary breast lymphoma (PBL) has gained attention with the description of breast implant-associated anaplastic large cell lymphoma (ALCL). Less is known about PBL incidence, treatment, and survival by lymphoma subtype. Methods: The Surveillance, Epidemiology, and End Results (SEER) registry database was queried for patients with PBL as first malignancy, with attention to non-Hodgkin Lymphoma PBL subtypes: diffuse large B-cell lymphoma (DLBCL), follicular lymphoma, marginal zone lymphoma (MZL), and ALCL...

Activating Janus kinase (JAK) and signal transducer and activator of transcription (STAT) mutations have been discovered in many T-cell malignancies, including anaplastic lymphoma kinase (ALK)(-) anaplastic large cell lymphomas (ALCLs). However, such mutations occur in a minority of patients. To investigate the clinical application of targeting JAK for ALK- ALCL, we treated ALK- cell lines of various histological origins with JAK inhibitors. Interestingly, most exogenous cytokine-independent cell lines responded to JAK inhibition regardless of JAK mutation status...

Primary cutaneous anaplastic large cell lymphoma (PC-ALCL) is a CD30+ lymphoproliferative disorder (LPD) of the skin with a relatively good prognosis in the absence of high-stage disease.[1] CD30+ LPDs comprise approximately 25-30% of primary cutaneous lymphomas and as a group represent the second most common clonal T cell neoplasm of the skin behind mycosis fungoides (MF).

Anaplastic large cell lymphoma (ALCL) is one of the most common peripheral T-cell lymphomas, and the incidence is higher in blacks than non-Hispanic whites. ALK-positive and ALK-negative ALCL are distinct subtypes that have different characteristics and clinical outcomes. Breast implant-associated ALCL is a rare lymphoma that has a good survival outcome, and a recent study showed that total capsulectomy is essential for treatment. Brentuximab vedotin (BV) is a standard treatment for relapsed/refractory ALCL...

Primary breast lymphoma is a rare disease and accounts for 0.5% of cases of breast cancer. Most primary breast lymphomas develop from B cells, and the involvement of T cells is rare. Anaplastic large cell lymphoma (ALCL) is a recently discovered T-cell lymphoma associated with breast implants. Only a few cases have been reported to date. It is believed that the incidence of ALCL is increasing because of the increasing number of breast implants. The clinical presentation is variable and can manifest as a palpable mass in the breast or armpit, breast pain, or capsular contracture...

Anaplastic large-cell lymphoma (ALCL) is a rare type of highly malignant, non-Hodgkin lymphoma (NHL). Currently, only studies on the chimeric oncogene NPM-ALK have reported a link to ALCL progression. However, the specific molecular mechanisms underlying the invasion of ALCL are still unclear. Here, we sought to investigate differentially expressed, long non-coding RNAs (lncRNAs) in ALCL and their potential biological function. Our microarray analyses revealed that LINC01013, a novel non-coding RNA gene, was highly expressed in clinical specimens of ALCL and was significantly upregulated in invasive ALCL cell lines...

Anaplastic large-cell lymphomas (ALCLs) are agroup of CD30-positive non-Hodgkin lymphomasthat are linked by common morphologic andimmunophenotypic features but have varyingclinical and genetic characteristics. The World HealthOrganization classification currently recognizes threesubtypes of ALCL: systemic anaplastic lymphomakinase-positive ALCL, systemic anaplastic lymphomakinase-negative (ALK-) ALCL, and primary cutaneousALCL. Here we present a 42-year-old man with ahistory of systemic ALK- ALCL, who was in remissionfor six months before relapsing with skin-limitedanaplastic large-cell lymphoma...

Anaplastic large cell lymphomas (ALCLs) are CD30-positive T-cell non-Hodgkin lymphomas that bear chromosomal rearrangements of the TP53 homologue, TP63, in a subset of cases that demonstrate aggressive clinical behavior. In the present study, we examined the relationship between p63 protein expression by immunohistochemistry and the results of fluorescence in situ hybridization (FISH) using TP63 probes in 116 ALCLs. We also determined the relative expression of full-length TAp63 and truncated ΔNp63 isoforms (e...
