Sézary syndrome: Report of a rare case with perioral manifestation and review of the literature.

This report aimed to describe a rare case of Sézary syndrome (SS) diagnosed in an Oral Medicine service. A 54-year-old female presented a generalized pruritus and erythema of the skin of 2 years in duration, which had been treated with antihistamines, corticosteroids, and hydrating creams, without resolution. Extra-oral examination showed a painful lymphadenopathy on the right supraclavicular region. Ultrasound-guided fine-needle aspirationbiopsy did not detect any abnormalities. The patient's skin was remarkably dry and thickened, with erythroderma, fissures, and ulcerations. The perioral region exhibited extreme peeling and angular cheilitis. Immunophenotyping of peripheral blood revealed proliferation of undifferentiated T-cells and a massive proportion of TCD4+ cells relative to TCD8+ cells. PET/CT examination demonstrated multiple lymphadenopathies, and bone marrow biopsy was negative for neoplastic cell infiltration. A diagnosis of SS was established, and the patient is currently being treated with UVB phototherapy, methotrexate, doxepin, and folic acid, with mostly complete regression of signs and symptoms.

Primary cutaneous T-cell lymphomas other than mycosis fungoides and Sézary syndrome. Part II: Prognosis and management.

Primary cutaneous T-cell lymphomas (CTCLs) other than mycosis fungoides (MF) and Sézary syndrome (SS) encompass a heterogenous group of non-Hodgkin lymphomas with variable clinical courses, prognoses, and management approaches. Given the morphologic and histologic overlap among the CTCL subtypes and other T-cell lymphomas with cutaneous manifestations, thorough evaluation with clinicopathologic correlation and exclusion of systemic involvement are essential prior to initiating therapy. Staging and treatment recommendations vary, depending on the subtype, clinical behavior, and treatment response. Generally, for subtypes in which staging is recommended, Ann Arbor or tumor, node, metastasis staging specific to CTCL other than MF or SS are used. For many subtypes, there is no standard treatment to date. Available recommended treatments range widely, from no active or minimal intervention with skin-directed therapy to aggressive systemic therapies that include multi-agent chemotherapy with consideration for hematopoietic stem cell transplant. Emerging targeted therapies, such as brentuximab, a chimeric antibody targeting CD30, show promise in altering the disease course of non-MF/SS CTCLs.

How we treat advanced stage cutaneous T-cell lymphoma - mycosis fungoides and Sézary syndrome.

T-cell lymphomas (TCLs) constitute a rare subset of non-Hodgkin lymphomas, with mycosis fungoides/Sézary syndrome (MF/SS) being the most common subtype of cutaneous TCLs (CTCLs). Considered an incurable but treatable disease, MF/SS management presents several challenges including diagnostic delays, debilitating effect on patients' quality of life, need for several lines of therapies, multidisciplinary care and cumulative drug toxicities limiting duration of use. The present review intends to provide an overview of the recent advances in our understanding of the biology of CTCL and how these are being leveraged to provide additional treatment options for management of advanced and recurrent disease. In addition, the discussion of the different modalities of treatment is summarised to further outline the importance of multidisciplinary care and early referral to CTCL centres.

[Cutaneous lymphomas : Clinical presentation - diagnosis - treatment]. / Kutane Lymphome : Klinik ­ Diagnostik ­ Therapie.

Cutaneous lymphomas comprise different subgroups with distinct biological behavior. Mycosis fungoides, the most common cutaneous lymphoma, presents with patches, plaques, tumors and erythroderma. Therapeutic options depend on stage and comprise local skin-directed treatment in early stages, while later stages and Sézary syndrome require systemic therapies including bexarotene, interferon or brentuximab vedotin. While the rare CD4-positive lymphoproliferation and acral CD8-positive lymphoma present with an invariably indolent course, cutaneous peripheral T­cell lymphomas exhibit an aggressive clinical behavior. Among the subgroup of cutaneous B­cell lymphomas, primary cutaneous marginal zone lymphoma and follicle center cell lymphoma belong to indolent entities with almost unrestricted overall survival, whereas cutaneous large B­cell lymphoma presents with a significant risk of systemic dissemination and is associated with high lethality.

Clinical Insights and Emerging Strategies in Managing Cutaneous T-Cell Lymphoma.

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. Utilization of Next-Generation Sequencing and other novel technologies has shed light on pathogenic mechanisms of CTCL, including immune dysregulation, antigen stimulation, and genomic alterations. CTCL management still remains a significant challenge due to lack of standardization of therapies for every stage of the disease. We provide a straightforward approach to clinical evaluation, diagnostic workup via immunophenotyping and molecular studies, staging guidelines, and select treatment strategies in Mycosis Fungoides and Sézary Syndrome. CTCL patients require individualized, holistic, and multidisciplinary care, for whom addressing management in different skin types and prioritizing quality of life issues are essential.

[Treatment of mycosis fungoides and Sézary syndrome]. / Therapie der Mycosis fungoides und des Sézary-Syndroms.

Adequate therapeutic management of cutaneous T-cell lymphoma (CTCL) requires the identification of the exact CTCL stage and entity within the current WHO classification. There is no curative therapy for CTCL yet, so that treatment currently aims at improving symptoms and quality of life as well as reducing relapse rates. The treatment has to be stage-adapted. Therapeutic options comprise skin-directed as well as systemic treatment. In early stages, phototherapy and local steroids are the first-line therapeutic options. For the therapy of higher stages, interferon alpha and the RXR-specific retinoid bexarotene are used as first-line medications. Second-line treatment comprises monochemotherapy with agents like gemcitabine or liposomal doxorubicine. Nevertheless, the high relapse rates in higher stages make novel alternative treatment options necessary. As future therapy, especially the fusion protein brentuximab-vedotin directed against CD30 shows promising potential in clinical studies.

Multidisciplinary Management of Mycosis Fungoides/Sézary Syndrome.

PURPOSE OF REVIEW: Diagnosis and management of mycosis fungoides and Sézary syndrome (MF/SS) require accurate clinicopathological correlation and a multidisciplinary approach. We reviewed major advances in the field regarding diagnostic and prognostic tools as well as skin-directed therapies (SDTs) and systemic agents for MF/SS published in the past 2 years. RECENT FINDINGS: Improved technology (T-cell receptor high-throughput sequencing) and increased multicenter collaboration (Cutaneous Lymphoma International Consortium) have led to diagnostic/prognostic advances. Concurrently, numerous genomic studies have enhanced understanding of disease pathogenesis. Advances in SDTs include topical resiquimod, a novel potent Toll-like receptor (TLR) agonist; consensus CTCL phototherapy guidelines; and use of low-dose radiation therapy. Novel systemic therapies for advanced disease of note include targeted antibody drug conjugates (brentuximab vedotin), immune checkpoint inhibitors, and allogeneic hematopoietic stem cell transplantation (HSCT). Our "toolbox" to diagnose and treat the spectrum of MF/SS continues to expand. Further characterization of genomic data going forward will enable a rational approach to selecting and combining therapies to improve patient care.

CD4-Positive T-Cell Large Granular Lymphocytosis Mimicking Sezary Syndrome in a Patient With Mycosis Fungoides.

A white woman aged 65 years presented with a macular, nonscaly, nonpruritic, erythematous lesion on her right breast. Test results revealed histological features similar to lichenoid dermatitis and early-phase primary cutaneous T-cell lymphoma with a subtype of mycosis fungoides (MF). Despite topical therapy with steroids, her skin disease continued to progress, so she underwent polymerase chain reaction and gene mutation testing. Two missense mutations were detected. The overall findings supported a diagnosis of co-occurring, CD4-positive large granular lymphocytosis and stage IA MF. The patient continued to receive topical steroids and maintenance phototherapy, and her skin lesions completely resolved after 14 weeks of therapy. Approximately 5 years after her initial presentation, she was free of symptoms, cytopenia, and no skin lesions were present. CD4-positive, large granular lymphocytosis was persistent. This patient case - to our knowledge, the first of its kind - posed dilemmas of a diagnostic and therapeutic nature. Correctly staging the lymphoma helped to aid the diagnosis and can help prevent patients similar to the one in this case from receiving unnecessary therapy.

Guidelines for phototherapy of mycosis fungoides and Sézary syndrome: A consensus statement of the United States Cutaneous Lymphoma Consortium.

BACKGROUND: Ultraviolet light (UVL) is a long established treatment for mycosis fungoides (MF) and Sézary syndrome (SS), subtypes of cutaneous T-cell lymphoma (CTCL). Treatments have traditionally included broadband, narrowband ultraviolet B light (UVB) and psoralen plus ultraviolet A light photochemotherapy (PUVA), but more recently, treatment options have expanded to include UVA1 and excimer laser. UVL is used either as monotherapy or as an adjuvant to systemic therapy, demonstrating efficacy in many cases that equal or surpass systemic medications. Despite its utility and duration of use, the current practice of using UVL guidelines for psoriasis to treat patients with MF/SS is problematic because the goals of prolonging survival and preventing disease progression are unique to CTCL compared to psoriasis. OBJECTIVES: We sought to develop separate guidelines for phototherapy for MF/SS for both clinical practice and for clinical trials. METHODS: Literature review and cutaneous lymphoma expert consensus group recommendations. RESULTS: This paper reviews the published literature for UVB and UVA/PUVA in MF/SS and suggests practical standardized guidelines for their use. LIMITATIONS: New standardization of phototherapy. CONCLUSIONS: These guidelines should allow the comparison of results with phototherapy in MF/SS across different stages of patients, centers, and in combination with other agents in practice and in clinical trials.

Vitamin D deficiency in mycosis fungoides and Sézary syndrome patients is similar to other cancer patients.

BACKGROUND: The purpose of this study was to determine the prevalence of vitamin D deficiency in CTCL patients and whether supplementation corrects vitamin D deficiency or treatment outcome. PATIENTS AND METHODS: Three hundred eleven CTCL patients including 27/311 (8.7%) with Sézary syndrome (SS), 169 cancer controls, and 69 normal controls from the M.D. Anderson clinics had 25(OH)D3 levels determined and categorized as deficient (< 20 ng/mL),insufficient (20-29 ng/mL), or sufficient (≥ 30 ng/mL). Clinical response was determined according to a change in percent body surface area involvement. RESULTS: Low 25(OH)D3 (< 30 ng/mL) levels were present in 76.9% of mycosis fungoides/SS patients, 75.2% of cancer controls, and 66.7% of healthy controls (P » .05, .07) and in 30% to 39% of historical normal controls. Correction of deficiency was successful in 35% or 55 of 156 patients who were given dealer's choice of either vitamin D2 at 50,000 IU orally (p.o.) biweekly or D3 1000 IU p.o. daily. Correction of vitamin D levels was noted in 27 of 100 (27%) patients given D3 and 28 of 56 (50%) given D2. Responses to standard CTCL therapy was similar among patients with corrected and persistently low levels (P » .51). CONCLUSION: To our knowledge,this is the first study of vitamin D status in CTCL patients. Vitamin D deficiency was present in CTCL and other cancer patients compared with normal and historical controls. Correction of vitamin D deficiency and type of vitamin D supplementation used did not affect the overall clinical disease response.

[New developments in Sézary syndrome]. / Actualités sur le syndrome de Sézary.

Sézary syndrome (SS) represents 3% of cutaneous T-cell lymphomas (CTCL). It is an aggressive epidermotropic CTCL with a 5-year survival rate of 24%. According to EORTC (European organization for research and treatment of cancer), SS is defined by erythroderma, diffuse lymphadenopathy, atypical T lymphocytes (>1000/mm(3)), and the presence of a major blood, cutaneous and nodal T cell clone. A specific marker for atypical tumoral T lymphocytes known as Sézary cells was identified in 2001, namely KIR3DL2 (CD158k) receptor, which allows more specific diagnosis of SS; levels of this marker are highly correlated with the clinical course of the disease. In therapeutic terms, clinical trials are being conducted on new molecules that point towards an improved prognosis for this disease. We propose a review of Sézary syndrome, which is currently the subject of scientific papers concerning both physiopathology and therapeutics, with new prospects of targeted therapy.

Diagnóstico y manejo del linfoma cutáneo de células T de tipo micosis fungoides y síndrome de Sèzary / Diagnosis and treatment of cutaneous T cells lymphoma

La micosis fungoides y el síndrome de Sèzary constituyen el grupo más frecuente de linfomas cutáneos de células T; tienen un curso lento y progresivo y un impacto negativo en la calidad de vida del paciente. En los estadios iniciales, la curación es anecdótica y en los casos avanzados pueden comprometer la vida del paciente; con las opciones terapéuticas actuales se consigue disminuir la sintomatología y se logran remisiones temporales. Para los estadios tempranos se propone el uso de terapias dirigidas a la piel, como los esteroides tópicos, la fotoquimioterapia PUVA y la radioterapia localizada, y otros no disponibles en nuestro medio, como la quimioterapia tópica y el bexaroteno, mientras que, para los estadios más avanzados, se recomiendan terapias que combinan las dirigidas a la piel con tratamientos sistémicos, como el interferón alfa, el vorinostat y la poliquimioterapia.

How I treat mycosis fungoides and Sézary syndrome.

The most common subtypes of primary cutaneous T-cell lymphomas are mycosis fungoides (MF) and Sézary syndrome (SS). The majority of patients have indolent disease; and given the incurable nature of MF/SS, management should focus on improving symptoms and cosmesis while limiting toxicity. Management of MF/SS should use a "stage-based" approach; treatment of early-stage disease (IA-IIA) typically involves skin directed therapies that include topical corticosteroids, phototherapy (psoralen plus ultraviolet A radiation or ultraviolet B radiation), topical chemotherapy, topical or systemic bexarotene, and radiotherapy. Systemic approaches are used for recalcitrant early-stage disease, advanced-stage disease (IIB-IV), and transformed disease and include retinoids, such as bexarotene, interferon-alpha, histone deacetylase inhibitors, the fusion toxin denileukin diftitox, systemic chemotherapy including transplantation, and extracorporeal photopheresis. Examples of drugs under active investigation include new histone deacetylase inhibitors, forodesine, monoclonal antibodies, proteasome inhibitors, and immunomodulatory agents, such as lenalidomide. It is appropriate to consider patients for novel agents within clinical trials if they have failed front-line therapy and before chemotherapy is used.

Review of the treatment of mycosis fungoides and sézary syndrome: a stage-based approach.

The NCCN Clinical Practice Guidelines in Oncology: Non-Hodgkin's Disease were recently revised to include recommendations for treating mycosis fungoides and Sézary syndrome. These uncommon lymphomas require a specialized evaluation and use a unique TNMB staging system. Unlike the other forms of non-Hodgkin's lymphomas, stage overwhelmingly determines prognosis and defines radically different treatment approaches. For patients with early-stage disease, initial treatment with skin-directed therapies is preferred, and many patients never require systemic therapy. For patients with refractory or advanced-stage disease, biologic therapies are often the first choices, whereas chemotherapies are reserved for later in the disease course. Many milder therapies may be repeated several times in the disease course, and maintenance and tapering strategies are common. This article also discusses the emerging role of allogeneic stem cell transplantation.

Prognostic factors in Sézary syndrome: a study of 28 patients.

BACKGROUND: The new European Organization for Research and Treatment of Cancer classification considers Sézary syndrome (SS) among the aggressive epidermotropic cutaneous T-cell lymphomas (ECTLs). Recent technological advances have facilitated the diagnosis of this disease, but it remains practically incurable, with a median survival of about 2.5-5 years. Deaths are due in part to the iatrogenic effects of treatments, which suggests that the management of SS could be improved. OBJECTIVES: Retrospectively to study the prognostic criteria related to disease progression. METHODS: Thirty patients with SS were followed up in the Dermatology Department of the University Hospital in Nantes, France, between January 1989 and May 2000. The diagnosis of SS was based on at least three of the following criteria: erythroderma, histological evidence of ECTL, a level of 20% or more circulating Sézary cells, and loss of My7 antigen expression by basal cells of the epidermis. Two patients not seen again after the initial diagnosis were excluded from the statistical study. RESULTS: The median disease-specific survival of the 28 patients was 64.55 +/- 10.11 months. The prognostic factors found in univariate analysis were age at diagnosis (P = 0.0109), interval before diagnosis (P = 0.0566), lactate dehydrogenase (LDH) level (P = 0.042) and presence of the Epstein-Barr virus (EBV) genome (BHLF in in situ hybridization) in skin (P = 0.0079). The prognostic factors found in multivariate analysis were age, interval before diagnosis and presence of the EBV genome in keratinocytes. A decreased number of Langerhans cells in the epidermis did not appear to be a prognostic factor. CONCLUSIONS: Our study confirms the prognostic value of age and LDH level, and for the first time demonstrates the prognostic value of the identification of the EBV genome in the skin. This seems consistent with a marked immune deficit during severe forms of SS.

Sézary syndrome: a summary.

Sézary syndrome is the leukemic form of primary cutaneous T-cell lymphoma. It is an aggressive disease, with the lowest reported median survival of all cutaneous lymphomas. Patients with Sézary syndrome live with the awareness that they are suffering from an incurable disease. Having to cope daily with extensive skin care regimens, these patients can benefit tremendously from the expertise of dermatology nurses, who can teach them skin selfcare and who are aware of the psychologic impact of this disease. The symptoms, treatments, and emotional distress related to Sézary syndrome are summarized.

[The Sézary syndrome]. / Síndrome de Sézary.

Sézary syndrome is a form of cutaneous T-cell lymphoma and, like mycosis fungoides, results from the malignant proliferation of mature post-thymic T-cell lymphocytes. The main features are the presence of abnormal mononuclear cells (Sezary cells) in the peripheral blood and exfoliative erythroderma. The authors present of a 70-year-old woman admitted to our clinic due to the case pruriginous and exfoliative erythroderma, subcutaneous nodes and lymphadenopathy. The clinical diagnosis of Sézary syndrome was confirmed through the identification of Sézary cells in the peripheral blood by cytochemistry and membrane marker studies and by lymph node histopathology. Genotypic studies excluded the presence of HTLV-I and HTLV-II sequences in DNA samples and confirmed the monoclonal nature and T-cell origin of this lymphoproliferative disease.

Pre-Sézary syndrome.

Eighteen patients with erythroderma, recurrent cycles of circulating Sézary cells of less than 1,000 cells/mm3, and a chronic course were followed for a mean time of nearly 5 years and were diagnosed as having pre-Sézary syndrome. Only one patient died, and none developed lymphoproliferative disease. All ten patients who underwent patch testing showed positive results. The elevation of IgE was striking when this group was compared with a group with Sézary syndrome. Most patients achieved partial or complete remission on low-dose chlorambucil and prednisone therapy. Some patients had lymphocytic or lymphomatoid bands on skin biopsy specimens and were like previously reported patients with pre-Sézary syndrome whose condition progressed to Sézary syndrome. A nontoxic chemotherapy or an anti-T cell treatment program can control this chronic erythroderma state.
