<p>Mycosis Fungoides and Sézary Syndrome, the two most common types of Cutaneous T-Cell Lymphoma (CTCL), present many management challenges for dermatologists. Here, we provide a comprehensive review of up-to-date literature, guidelines, and expert clinical insights. We highlight the updates in the World Health Organization Classification of Cutaneous Lymphomas; we summarize the epidemiology, including a recently observed stabilization of increasing incidence of CTCL in the past decade and increased incidence in males, blacks, and veterans; we also provide the most recent updates on prognostic factors for CTCL...

Sézary syndrome is an extremely rare form of cutaneous T-cell lymphoma. It presents suddenly and is associated with a poor prognosis. Clinical recognition is crucial for the diagnostic process and initiation of appropriate treatment. Plantar keratoderma is usually pathognomonic for Sézary syndrome and clinicians should be alerted to its presence.

HDAC inhibitors are promising agents for various T-cell lymphomas, including cutaneous T-cell lymphoma, peripheral T-cell lymphoma, and adult T-cell lymphoma/leukemia. CCR4 is an important therapeutic target molecule because mogamulizumab, an anti-CCR4 antibody, has shown promising efficacy against various T-cell lymphomas. In this study, we examined the in vitro synergistic effects of mogamulizumab and HDAC inhibitors against various T-cell lymphomas. First, we examined the expression of CCR4 mRNA and surface CCR4 in various T-cell lymphoma cell lines and found it was downregulated upon treatment with vorinostat, a pan-HDAC inhibitor...

Cutaneous T-cell lymphomas (CTCLs) are a heterogeneous group of malignancies with courses ranging from indolent to potentially lethal. We recently studied in a 157 patient cohort gene expression profiles generated by the TruSeq targeted RNA gene expression sequencing. We observed that the sequencing library quality and depth from formalin-fixed paraffin-embedded (FFPE) skin samples were significantly lower when biopsies were obtained prior to 2009. We also observed that the fresh CTCL samples clustered together, even though they included stage I-IV disease...

Laryngeal involvement is a rare manifestation of mycosis fungoides (MF), with only nine reported cases of cutaneous T cell lymphoma with laryngeal or vocal cord involvement. Herein, we report the case of a patient with a 7-year history of MF who presented to the emergency department with hoarseness, throat tightness and cough, as well as erythroderma and skin tumours. Laryngoscopy and CT imaging were concerning for lymphomatous involvement of the left false vocal cord. A biopsy was taken of the false vocal cord lesion, which revealed an aberrant immunophenotype consistent with MF...

Over a 2 year period a 32-year-old woman developed swellings of all 4 eyelid margins accompanied by complete loss of eyelashes. An inflammatory dermatologic condition was considered the most likely cause. A full thickness right lower eyelid biopsy revealed a multinodular lymphoid tumor at the eyelid margin which immunophenotypically and genetically was diagnosed as an extranodal marginal zone lymphoma. The mode of presentation of the disease was considered to be most unusual, as was its B cell lineage, since the majority of primary cutaneous lymphomas are of T-cell origin...

CD8 T-cell lymphomas comprise a wide spectrum of lymphomas, many which have yet to be formally classified. We present a case of a 43-year-old woman with an enlarging tumor distal to the distal interphalangeal joint of the fourth finger, compressing the underlying nail matrix. Magnetic resonance imaging showed bony involvement of the underlying distal phalanx. Histology showed a dense epidermotropic and pandermal infiltrate composed of medium-sized, uniformly pleomorphic lymphocytes with cleaved nuclei, which raised the possibility of primary cutaneous CD8 aggressive epidermotropic cytotoxic T-cell lymphoma...

Cutaneous T-cell lymphomas (CTCLs) are extremely symptomatic and still incurable, and more effective and less toxic therapies are urgently needed. ONC201, an imipridone compound, has shown efficacy in pre-clinical studies in multiple advanced cancers. This study was to evaluate the anti-tumor activity of ONC201 on CTCL cells. The effect of ONC201 on the cell growth and apoptosis were evaluated in CTCL cell lines (n=8) and primary CD4(+) malignant T cells isolated from CTCL patients (n=5). ONC201 showed a time-dependent cell growth inhibition in all treated cell lines with a concentration range of 1...

BACKGROUND: Mycosis fungoides (MF) is the major subtype of cutaneous T-cell lymphomas (CTCL). It usually has a prolonged indolent clinical course with a minority of cases acquiring a more aggressive biological profile and resistance to conventional therapies, partially attributed to the persistent activation of Nuclear Factor-kappa B (NF-κB) pathway. In the last decade, several papers suggested an important role for the FK506-binding protein 51 (FKBP51), an immunophilin initially cloned in lymphocytes, in the control of NF-κB pathway in different types of human malignancies...

BACKGROUND: T-cell lymphomas with anaplastic morphology typically comprise of anaplastic lymphoma kinase positive, anaplastic large cell lymphoma (ALK+ ALCL), ALK-negative ALCL (ALK- ALCL), and primary cutaneous ALCL (PC-ALCL). However, other entities such as diffuse large B-cell lymphoma, peripheral T-cell lymphoma, Hodgkin lymphoma, and undifferentiated carcinoma can also show similar anaplastic features. AIMS: To study the clinical features and histological spectrum of ALCL and emphasize the role of immunohistochemistry (IHC) in their diagnosis and categorization...

The presence and degree of peripheral blood involvement in patients with cutaneous T-cell lymphoma (CTCL) portend a worse clinical outcome. Available systemic therapies for CTCL may variably decrease tumor burden and improve quality of life, but offer limited effects on survival; thus, novel approaches to the treatment of advanced stages of this non-Hodgkin lymphoma are clearly warranted. Mutational analyses of CTCL patient peripheral blood malignant cell samples suggested the anti-apoptotic mediator BCL2 as a potential therapeutic target...

Primary cutaneous CD4+ small/medium sized pleomorphic T-cell lymphoma (SMPTCL) is unique among the peripheral T-cell lymphomas because of its indolent nature, typically presenting as a solitary nodule or plaque in the head and neck area of middle-aged and older adults. Recent studies have suggested a follicular helper cell origin for these lesions. MATERIALS AND METHODS: A retrospective review was conducted on all cases of SMPTCL diagnosed between 2008 and 2017. The goal of our study was to better categorize the clinical, pathologic and molecular features of cases of SMPTCL showing a significant degree of CD30 neoplastic large cell infiltration...

Infective dermatitis associated with HTLV-1 (IDH) is the main cutaneous marker of HTLV-1 infection. This disease occurs primarily in children and should be differentiated from other eczemas, especially from atopic dermatitis. The largest series of IDH are from Jamaica and Brazil. There are an estimated 15 to 20 million infected people in the world, and Brazil is one of the endemic regions. Studies suggest that IDH in children may be a marker for the development of T-cell leukemia/lymphoma (ATL) or myelopathy associated with HTLV-1/tropical spastic paraparesis (HAM / TSP) in adulthood...

Background: Mycosis fungoides (MF) is the commonest variant of primary cutaneous T cell lymphoma with several clinicopathologic variants. Defective apoptotic mechanism may be important in the pathogenesis and progression of MF. c-FLIP protein is an important anti-apoptotic marker and chemotherapeutic resistant factor. This study aimed to evaluate the c-FLIP expression in MF and its role in the pathogenesis of MF. Methods: Twenty patients of MF and ten normal persons were included in this study. Skin biopsies were obtained from both patients and controls...

Regulatory T cells (Treg) can be divided into two types: the natural cells (tTreg), which arise in the thymus, and the induced cells (iTreg), which are produced in peripheral tissues during immune response. The most recently published studies indicate that the supervisory functions of these cells are weakened in the pathogenesis of autoimmune and neoplastic diseases of the skin. This may be a result of the domination of other immune cells in the skin, such as Th1/Th17/Th22 and Tc1 type in psoriasis and Th2 in atopic dermatitis...

Skin biopsies of 41 angioimmunoblastic T-cell lymphoma patients were retrospectively analyzed for the expression of follicular helper T-cell (TFH) markers, Epstein-Barr virus (EBV), and the presence of RHOA (p.G17V) and IDH2 (p.R172K/S) mutations using allele-specific polymerase chain reaction. We categorized cases into 4 distinctive patterns: (1) low-density lymphocytic perivascular infiltrates (n=11), (2) dense perivascular infiltrates with atypical cells and occasional inflammatory cells (n=13), (3) diffuse infiltrates reminiscent of angioimmunoblastic T-cell lymphoma (n=4), or (4) other aspects (n=13)...

Richter syndrome represents the transformation of chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma into an aggressive large B-cell lymphoma. Skin involvement is exceptionally rare, with <20 cases reported and its presence as the first presentation of CLL/small lymphocytic lymphoma, as an isolated skin lesion has never been described. Primary cutaneous CD4-positive small/medium T-cell lymphoma (CD4 PCSM-TCL) characteristically presents with a dense dermal infiltrate consisting primarily of small-/medium-sized pleomorphic T-cells and less than 30% large pleomorphic cells...

Facilitating the development of alternative targeted therapeutic strategies is urgently required to improve outcome or circumvent chemotherapy resistance in children, adolescents, and adults with recurrent/refractory de novo mature B-cell (CD20) non-Hodgkin lymphoma, including Burkitt lymphoma (BL). Romidepsin, a histone deacetylase inhibitor (HDACi), has been used to treat cutaneous T-cell lymphoma. We have demonstrated the significant anti-tumor effect of anti-CD20 chimeric antigen receptor (CAR) modified expanded peripheral blood natural killer (exPBNK) against rituximab-sensitive and -resistant BL...
