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...

IL-31 is a recently identified cytokine with a well-defined role in the pathogenesis of pruritus. IL-31, whose production is induced by IL-4 and IL-33, binds a heterodimeric receptor (R) composed of the exclusive IL-31RA chain and the shared oncostatin M R. Signaling through the IL-31R involves the MAPK, PI3K/AKT and Jak/STAT pathways. Different variants and isoforms of IL-31RA with different signaling activities have been identified. IL-31 is produced predominantly by circulating Th2 lymphocytes and skin-homing CLA(+)CD45RO(+) T cells...

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)...

Mycosis fungoides (MF) is the most common type of primary cutaneous lymphomas. Several clinical variants of MF have been described. Purely, hypopigmented variant of MF (HMF) is rare. Phototherapy, especially photochemotherapy (Psoralen and ultraviolet), is the most widely used method and is recommended as the first-line treatment for HMF. However, there are no standard guidelines for phototherapy as the disease is uncommon. We, hereby, report a 30-year-old woman with HMF in whom clinical, histopathological, and immunohistochemical remission was achieved following narrow-band ultraviolet B therapy...

Cutaneous T-cell lymphoma (CTCL) commonly presents as mycosis fungoides or Sezary syndrome, both having CD4 positivity. A subset of CTCL which lacks CD4 surface marker is classified as cutaneous γ and δ-T-cell lymphoma (CGD-TCL). Because of its rarity and inability to study large number of patients, the impact of immunophenotype on the clinical outcome of primary CTCL in patients is limited. We report a case of primary CGD-TCL in a 71-year-old male because of this rarity and to emphasize its aggressive nature...

BACKGROUND: Nonmycosis fungoides/Sézary syndrome (non-MF/SS) primary cutaneous lymphomas (PCL) are currently categorized under the 2005-World Health Organization/European Organization for Research and Treatment of Cancer (WHO-EORTC) classification for PCL. These differ in behavior from secondary cutaneous lymphomas (SCL) and to lymphomas limited to the oral cavity (primary oral lymphomas [POL]) both categorized under the 2016-WHO classification for lymphoid neoplasms. AIMS: This study aims to report the first series of non-MF/SS PCL, SCL, and POL in a Mexican cohort, examine the applicability of current classification systems and compare our findings with those from foreign cohorts...

Cutaneous T-cell lymphomas (CTCLs) represent a group of rare and heterogeneous diseases that are very difficult to treat at advanced stages. The development of monoclonal antibodies is a new hope for the treatment of these diseases. Alemtuzumab (Campath) is a humanized IgG1 kappa monoclonal antibody specific for CD52, an antigen expressed by most T and B lymphocytes. Alemtuzumab may frequently induce long-term remissions in patients with Sezary syndrome but high-dose treatments lead to severe cytopenia, immune depletion, and opportunistic infections...

Mycosis fungoides is the most common primary cutaneous T-cell lymphoma. The approach to diagnosis and further follow-up is outlined. Evidence for interventions is based classically on a Tumor Node Metastasis Blood TNMB "stage-based" approach. The treatment options in India are limited. The options as per risk stratification and prognostic index are discussed. Early stages and low-risk patients can be managed with expectant policy or skin-directed therapies including topical steroids and phototherapy; intermediate-risk patients can be opted for interferons or retinoids or low dose methotrexate along with radiotherapy including total skin electron beam therapy while high-risk patients are managed most often with single agent or multiagent palliative chemotherapy...

BACKGROUND: Granulomatous slack skin (GSS) is an extremely rare subtype of T-cell lymphoma, a variant of mycosis fungoides (MF). Herein, we describe the first reported case of GSS associated with metastatic testicular seminoma. PATIENTS AND METHODS: A 28-year-old male patient presented with circumscribed erythematous loose skin masses, especially in the body folds and which had been relapsing for 4years. Skin biopsy showed a loss of elastic fibers and an atypical granulomatous T-cell infiltrate with epidermotropism, enabling a diagnosis of GSS to be made...

We retrospectively reviewed data pertaining to five patients with cutaneous T-cell lymphoma (CTCL) who had received hematopoietic stem cell transplantation (HSCT) between 2004 and 2015 at Kurume University Hospital, along with their clinical data until March 2016. For patients with advanced CTCL eligible for HSCT, autologous HSCT was performed when they responded well to chemotherapy, and allogeneic HSCT was selected for patients with advanced mycosis fungoides (MF)/Sézary syndrome (SS) and CTCL other than MF/SS with poor chemosensitivity...

Primary cutaneous follicular helper T-cell (Tfh) lymphoma is a recently described variant of peripheral T-cell lymphoma-not otherwise specified. This particular variant, usually presenting as a sudden onset of multiple plaques and nodules, is characterized by tumoral atypical T cells that express an array of Tfh markers, such as inducible T-cell costimulator, Bcl-6, CXCL13, PD-1, and CD10. The authors now present 3 patients whose known clinical skin findings are consistent with PTCL of Tfh origin (PTCL-Tfh)...

In order to provide a common standard for the treatment of mycosis fungoides (MF) and Sézary syndrome (SS), the European Organisation for Research and Treatment of Cancer-Cutaneous Lymphoma Task Force (EORTC-CLTF) published in 2006 its consensus recommendations for the stage-adapted selection of management options for these neoplasms. Since then, the understanding of the pathophysiology and epidemiology of MF/SS has advanced, the staging system has been revised, new outcome data have been published and novel treatment options have been introduced...

Mycosis fungoides (MF) progresses from patch to tumor stage by expansion of malignant T-cells that fail to be controlled by protective immune mechanisms. In this study, we focused on IL-32, a cytokine, highly expressed in MF lesions. Depending on the other cytokines (IL-4, GM-CSF) present during in vitro culture of healthy volunteers' monocytes, IL-32 increased the maturation of CD11c(+) myeloid dendritic cells (mDC) and/or CD163(+) macrophages, but IL-32 alone showed a clear ability to promote dendritic cell (DC) differentiation from monocytes...

Background: The differential for soft tissue tumors of the hand and upper limb is broad. Hematologic malignancy remains quite low on the differential for soft tissue tumors involving the hand, and there is little in the literature describing surgical management of such cutaneous manifestations. When the tumor is large or involves the thumb, careful consideration of reconstructive options is required. Methods: We present a rare case of an aggressively enlarging mycosis fungoides, a cutaneous T-cell lymphoma tumor, involving the thumb...

Dermatosis characterized by tissue eosinophilia arising in the context of hematologic disease is known as eosinophilic dermatosis of hematologic malignancy. The most commonly associated malignancy is chronic lymphocytic leukemia. Eosinophilic dermatosis of hematologic malignancy is a rare condition with a wide variety of clinical presentations, ranging from papules, erythematous nodules, or blisters that simulate arthropod bites, to the formation of true plaques of differing sizes. Histology reveals the presence of abundant eosinophils...

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).

Mycosis fungoides and the Sezary syndrome (SS) are rare lymphomas of CD4(+) helper T cells. There is stagewise progression from patch/plaques to thicker tumor lesions/diffuse erythroderma. Blood involvement is a characteristic of SS. Outcomes are related to the extent of skin, blood, lymph node, and visceral organ involvement. Patients with limited patch and plaque disease are treated with skin-directed therapies. More advanced/refractory disease is treated with skin-directed therapies and oral or systemic immunomodulatory agents...
