Mycosis fungoides is the most common Cutaneous T cell lymphoma. Selection of appropriate treatment for mycosis fungoides is based on prognostic factors and overall clinical stage at diagnosis. In the past decade, clinical success has been reported using photodynamic therapy as an alternative target-specific therapy to treat mycosis fungoides. This review aimed to summarize the current advances in management of mycosis fungoides by administration of photodynamic therapy.

Bexarotene is a third-generation retinoid X receptor-selective retinoid that is widely used for the early treatment of advanced-stage cutaneous T-cell lymphomas. In this report, we describe a case of successful treatment of advanced primary cutaneous peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) with oral bexarotene monotherapy. After the administration of oral bexarotene at a dose of 300 mg/m2 /day, all skin lesions and lymph nodes regressed, and complete remission was achieved for 1 year. Our case suggested that bexarotene monotherapy could be one of the possible therapies for the treatment of primary cutaneous PTCL-NOS...

In recent years, much has been learned about the molecular genetics of cutaneous T-cell lymphomas. Fanok et al. (2018) translate knowledge from systematic genomic and transcriptomic analyses to develop a mouse model that tests the hypothesis that activated STAT3 in CD4+ T cells may be a driver of cutaneous T-cell lymphomas. The transgenic mouse that they developed exhibits clinical features of mycosis fungoides, as well as Sezary syndrome, two well-known entities in the cutaneous T-cell lymphoma spectrum. Furthermore, these authors show that TCR engagement and microbiota are required for development of the complete clinical phenotype...

Primary cutaneous CD30+ T cell lymphoproliferative disorders (PCLPD), the second most common type of primary cutaneous T cell lymphomas, accounts for approximately 25-30% of cutaneous T-cell lymphoma cases. However, only small retrospective studies have been reported. We aimed to identify prognostic factors and evaluate the overall survival (OS) of patients with PCLPD stratified by ethnicity. We identified 1496 patients diagnosed with PCLPD between 2004 and 2014 in the US National Cancer Database. Chi-square test and anova were used to evaluate differences in demographic and disease characteristics, socioeconomic factors and treatments received...

Aminolevulinate-based photodynamic therapy (ALA-PDT) selectively eliminates diseased tissues primarily through the induction of intrinsic apoptotic pathway. ALA-PDT is a first-line therapy for actinic keratosis, however, it is less effective for cutaneous T-cell lymphoma (CTCL). We have previously demonstrated that the resistance of CTCL to apoptosis correlates with decreased expression of death receptors such as FAS, and that methotrexate functions as an epigenetic regulator that re-establishes the susceptibility of CTCL to extrinsic pathway apoptosis...

Ibrutinib has previously been shown to inhibit Bruton's tyrosine kinase (BTK) and interleukin-2-inducible T-cell kinase (ITK), which mediate B-cell and T-cell receptor signaling, respectively. BTK inhibition with ibrutinib has demonstrated impressive clinical responses in a variety of B-cell malignancies. Whether ibrutinib inhibition of ITK can lead to clinical response in T-cell malignancies is unknown. We hypothesized that ibrutinib-mediated ITK inhibition in T-cell lymphoma would result in decreased signaling through the T-cell receptor pathway and promote antitumor immune response by driving selective cytotoxic Th1 CD4 effector T-cell differentiation...

A 43-year-old Malaysian man with well-controlled HIV infection on combination antiretroviral therapy presented with a six-week history of a widespread rash. The patient was otherwise well but was developing new lesions on a daily basis. Referral to Dermatology instigated punch biopsies, which revealed a diagnosis of lymphomatoid papulosis type A. This case highlights the importance of swift referral, especially in cases of spontaneous regression of symptoms, in order to obtain the correct diagnosis. In most patients, this condition tends to be chronic, with its chronicity and benign clinical course setting it apart from cutaneous anaplastic T-cell lymphoma and Hodgkin's disease, which are major entities in the histological differential diagnosis...

Primary pulmonary lymphoma is defined as clonal lymphoid proliferation affecting one or both lungs in a patient with no extrapulmonary involvement at the time of diagnosis or during the subsequent 3 months. Anaplastic large cell lymphoma (ALCL) is a rare T-cell neoplasm which occurs as two distinct clinical entities-cutaneous and systemic variant. Primary lung involvement is extremely uncommon. It can be classified on the basis of being positive or negative for ALK rearrangement which carries prognostic significance...

Anaplastic large cell lymphoma (ALCL) represents a group of malignant T-cell lymphoproliferations that share morphological and immunophenotypical features, namely strong CD30 expression and variable loss of T-cell markers, but differ in clinical presentation and prognosis. The recognition of anaplastic lymphoma kinase (ALK) fusion proteins as a result of chromosomal translocations or inversions was the starting point for the distinction of different subgroups of ALCL. According to their distinct clinical settings and molecular findings, the 2016 revised World Health Organization (WHO) classification recognizes four different entities: systemic ALK-positive ALCL (ALK+ ALCL), systemic ALK-negative ALCL (ALK&minus; ALCL), primary cutaneous ALCL (pC-ALCL), and breast implant-associated ALCL (BI-ALCL), the latter included as a provisional entity...

Papuloerythroderma of Ofuji (PEO) is an erythroderma-like eruption with flat-topped papules that spare the skin folds (a "deck-chair sign" finding). Many infections, medications, and systemic diseases have been associated with PEO, including cutaneous T-cell lymphomas (CTCL). The relationship between the clinical presentation of PEO and CTCL remains poorly elucidated. Clinical, laboratory, and histopathological data were obtained from the Lymphoma Clinic at the Ottawa Hospital, Canada. We report 5 patients with deck-chair-sign-positive CTCL, mycosis fungoides, and Sézary syndrome variants...

BACKGROUND: Folliculotropic mycosis fungoides (FMF) is a cutaneous T-cell lymphoma mainly affecting the hair follicle, which seems to represent a place of immune privilege phenomenon. OBJECTIVES: To explore a possible role of immune privilege (IP) in FMF analyzing the major histocompatibility complex (MHC) expression. METHODS: Immunohistochemistry for HLA-G and MHC-II was performed to formalin-fixed paraffin-embedded cutaneous skin biopsies of FMF patients (n = 43), conventional mycosis fungoides (CMF; n = 13), alopecia areata (AA; n = 13), and normal scalp skin (NS; n = 12)...

BACKGROUND: Bexarotene (Targretin® ) is currently the only FDA approved retinoid X receptor (RXR) -selective agonist for the treatment of cutaneous T-cell lymphomas (CTCLs). The main side effects of bexarotene are hypothyroidism and elevation of serum triglycerides (TGs). The novel RXR ligand, 9-cis UAB30 (UAB30) does not elevate serum TGs or induce hypothyroidism in normal subjects. OBJECTIVES: To assess preclinical efficacy and mechanism of action of UAB30 in the treatment of CTCLs and compare its action with bexarotene...

During the treatment of extracorporeal photopheresis (ECP), white blood cells are collected by apheresis and exposed to ultraviolet A after incubation with 8-methoxypsoralen. Although ECP was first developed for cutaneous T cell lymphoma, it has shown promising efficacy in a number of other serious conditions, like acute and chronic graft-versus-host disease, lung and cardiac transplant rejection and other autoimmune diseases. The ECP has been used for thirty years in some specialized centers but remains unknown to most of the physicians...

Peripheral T-cell lymphomas not otherwise specified (PTCLs-NOS) have been defined as a kind of "Pandora's box", because of the broad morphologic spectrum, which features a prevalent nodal involvement and an aggressive, yet non-specific clinical course1,2 . PTCLs-NOS usually have a nodal presentation, while a skin spread occurs in approximately 20% of cases3 being regarded as a worse prognostic factor4,5,6 . PTCLs-NOS featuring skin lesions present at least six months before a hypothetical systemic involvement are regarded as a separate entity, named primary cutaneous PTCLs-NOS (PC-PTCLs-NOS)3,4,7 ...
