Abstract
Recent developments in immunotherapy against malignancies overcome the disadvantages of traditional systemic treatments; however, this immune checkpoint treatment is not perfect and cannot obtain a satisfactory clinical outcome in all cases. Therefore, an additional therapeutic option for malignancy is needed in oncology. Stimulator of interferon genes (STING) has recently been highlighted as a strong type I interferon driver and shows anti-tumor immunity against various malignancies. STING-targeted anti-tumor immunotherapy is expected to enhance the anti-tumor effects and clinical outcomes of immunotherapy against malignancies. In this review, we focus on recent advancements in the knowledge gained from research on STING signaling in skin cancers. In addition to the limitations of STING-targeted immunotherapy, we also discuss the clinical application of STING agonists in the treatment of skin cancer.

Abstract
Sézary syndrome (SS) is a form of cutaneous T-cell lymphoma (CTCL), demonstrating leukemic involvement of malignant T-cells. Known systemic sequelae of SS include hemophagocytic syndrome-induced anemia, normocytic anemia secondary to bone marrow infiltration, and pancytopenia. We report a patient with SS, initially demonstrating widespread morbilliform eruption, who presented with malignancy-related microangiopathic hemolytic anemia (MAHA). Our findings represent a novel presentation of SS that will inform the differential diagnosis and treatment of future SS patients presenting with anemia and thrombocytopenia.

Abstract
Cell adhesion ability is one of the components to establish cell organization and shows a great contribution to human body construction consisting of various types of cells mixture to orchestrate tissue specific function. The cell adhesion molecule 1 (CADM1) is a molecule of cell adhesion with multiple functions and has been identified as a tumor suppressor gene. CADM1 has multifunctions on the pathogenesis of malignancies, and other normal cells such as immune cells. However, little is known about the function of CADM1 on cutaneous cells and cutaneous malignancies. CADM1 plays an important role in connecting cells with each other, contacting cells to deliver their signal, and acting as a scaffolding molecule for other immune cells to develop their immune responses. A limited number of studies reveal the contribution of CADM1 on the development of cutaneous malignancies. Solid cutaneous malignancies, such as cutaneous squamous cell carcinoma and malignant melanoma, reduce their CADM1 expression to promote the invasion and metastasis of the tumor. On the contrary to these cutaneous solid tumors except for Merkel cell carcinoma, cutaneous lymphomas, such as adult-T cell leukemia/lymphoma, mycosis fungoides, and Sézary syndrome, increase their CADM1 expression for the development of tumor environment. Based on the role of CADM1 in the etiology of tumor development, the theory of CADM1 contribution will desirably be applied to skin tumors according to other organ malignancies, however, the characteristics of skin as a multicomponent peripheral organ should be kept in mind to conclude their prognoses.

Abstract
Background: The onychodystrophies associated with Sézary syndrome (SzS) have rarely been described in the literature. We performed a retrospective analysis of SzS patients at a single institution and compared our data with previous publications. Objectives: The objectives of this study were to identify and describe the most frequent nail alterations in patients with SzS. Methods: A retrospective analysis was performed with some prospective observations at the University of Pittsburgh from 1989 to 2017. Results: We identified 54 patients with SzS out of 535 patients with cutaneous T-cell lymphoma. Nineteen patients with SzS had photos of their nail. All those patients exhibited some type of onychodystrophy. The most common types were paronychia (63.2%; 12/19), leukonychia (42.1%; 8/19), onycholysis (42.1%; 8/19), trachyonychia (31.6%; 6/19), and subungual hyperkeratosis (26.3; 5/19). Cluster analysis of our data in comparison with published data on the psoriatic nails indicated that while leukonychia, onycholysis, subungual hyperkeratosis, and nail discoloration were frequently observed in psoriasis, onychauxis, anonychia, distal notching, and onychoschizia occurred more commonly in patients with SzS. Conclusions: The most common nail manifestations in SzS patients included paronychia, leukonychia, and onycholysis. The nail manifestations in SzS patients appeared to be heterogeneous, while onychauxis, anonychia, distal notching, and onychoschizia seem to be specific to SzS in comparison with psoriasis.

Abstract
Primary cutaneous lymphomas are a heterogeneous group that includes 2 main groups of primary T- and B-cell lymphomas, which can involve the skin with distinct variability in clinical presentation, histopathology, immunophenotypes, molecular signature, and prognosis. The authors describe the most frequent clinical forms of cutaneous lymphomas and their dermoscopic features. Even if the diagnosis of these entities is still based on a cellular level and the literature on dermoscopy in cutaneous lymphomas is limited and, for several entities it is based only on single case reports/case series, we think that know how they appear also in dermoscopy can be useful for helping in the clinical diagnosis.

Abstract
Background Cutaneous T-cell lymphoma (CTCL) represents a spectrum of diseases composed of malignant T lymphocytes. The most common type is mycosis fungoides (MF). An accurate diagnosis of early MF may be difficult because of the varied clinical and histologic expressions of the disease. Methods The authors review the epidemiology, possible risk factors, clinical manifestations, diagnostic techniques, staging, prognosis, and treatment options for MF. Results The varied and often nonspecific clinical and bistologic presentations of MF may delay diagnosis and staging, thus necessitating further studies such as immunophenotyping and T-cell receptor gene rearrangement analysis. Conclusions A multidisciplinary approach to the diagnosis, staging, and treatment of MF assists in optimizing outcomes from management of patients with this disease.

Abstract
Primary cutaneous lymphomas can be diagnosed when the clinical symptoms, histology, immunohistology and molecular biological changes are characteristic of primary cutaneous T or B‑cell lymphomas; however, in many cases not all of the changes are typical of a primary cutaneous lymphoma especially in the early stages; therefore, the diagnosis of a primary cutaneous lymphoma can be a challenge. This is especially true for the Sézary syndrome, which can initially prove to be difficult to differentiate from reactive erythroderma; therefore, the main focus of this review is the diagnostics of Sézary syndrome. The review also summarizes the clinical heterogeneity and describes the classical histological and immunohistochemical changes for the diagnosis of Sézary syndrome. Recent data from different multicenter, international studies by the cutaneous lymphoma task force of the European Organisation for Research and Treatment of Cancer (EORTC) on dermatological alterations of the skin and the detection of Sézary cells in blood are addressed. The detection of Sézary cells in the blood still remains a challenge despite improved molecular boiological and cytogenetic characterization of tumor cells. The latest studies of the EORTC group particularly identified CD158k, MYC, MNT, DNM, TWIST1, EPHA4 and PLS3 as valuable markers for the differentiation of reactive erythroderma but which are not yet part of the standard diagnostics of Sézary syndrome. Further studies are required to see if these markers can be used in the routine clinical application.

Abstract
Cutaneous T-cell lymphomas (CTCLs) are a heterogeneous group of extranodal lymphomas involving the skin. Diagnosis of the two main subtypes of CTCL-mycosis fungoides (MF) and Sézary syndrome (SS)-is based on the International Society for Cutaneous Lymphomas/European Organization for Research and Treatment of Cancer (ISCL/EORTC) classification system, which utilizes clinical, histopathological, molecular biologic, and immunopathologic features. Risk stratification, based on TNMB (tumor, node, metastasis, and blood) staging, provides prognostic information, with limited-stage disease conferring the longest median overall survival. Skin-directed therapies are preferred in the management of limited-stage disease, whereas advanced-stage disease requires systemic therapies. As the mechanisms of CTCL pathogenesis are increasingly understood, new monoclonal antibodies, checkpoint inhibitors, immunomodulatory agents, and small molecules are under investigation and may provide additional therapeutic options for those with advanced CTCL. This review examines the current landscape of targeted therapies in the treatment of CTCLs.

Abstract
Sézary syndrome is an aggressive variant of cutaneous T cell lymphoma with poor prognosis and clinically characterized by erythroderma and Sézary cells in the blood. Here we report a case of bullous Sézary syndrome. A seventy-year-old male presented with erythroderma and inguinal lymph node swelling. Histopathological examination showed dermal and epidermal infiltration of atypical lymphocytes and Sézary cells could be detected in peripheral blood samples. He was therefore diagnosed as Sézary syndrome. Four months after the onset, he developed bullae on axillary and inguinal areas, featuring subepidermal blistering with basal cell degeneration and dense infiltration of atypical lymphocytes. Autoimmune bullous diseases were excluded by negative immunofluorescence. Bullous forms of Sézary syndrome are extremely rare although several cases of a bullous variant of mycosis fungoides have been reported.

Abstract
AIM The aim of this paper was to present diagnostic methods helping in the recognition of mycosis fungoides (MF) and Sezary syndrome (SS). BACKGROUND Mycosis fungoides is the most common form of primary cutaneous T-cell lymphomas. It is characterized by a distinctive long-term course and malignant T-cell proliferation. MF diagnosis is not easy, mainly due to the atypical clinical presentation of the disease at an early stage. MATERIALS AND METHODS Low specific changes, which can be observed at the histopathological examination. Initially, the skin lesions may resemble psoriasis, atopic dermatitis or chronic eczema. Patients are qualified according to the available, and generally accepted WHO-EORTC classification, based on a combination of clinical and histopathological markers. From a clinical point of view, it is also important to carry out the qualification according to the TNMB assessment, which allows to specify the stage of the disease, and is helpful in the monitoring of the course of disease and therapeutic effects. RESULTS In this paper we try to present currently available diagnostic methods. CONCLUSION Diagnosis of MF and SS still causes many problems due to less characteristic changes in the early stage of disease and requires wide interdisciplinary knowledge.

Abstract
Objective: To evaluate the efficacy and safety of romidepsin in refractory cutaneous T-cell lymphoma (CTCL). Data Sources: An English-language literature search of PubMed and MEDLINE (Nov 2011–April 2012) was performed using the terms romidepsin, CTCL, and depsipeptide (FK228). The National Comprehensive Cancer Network guidelines, American Society of Clinical Oncology abstracts, American Society of Hematology abstracts, clinical trial registry, and prescribing information from the manufacturer were reviewed for additional information. Study Selection and Data Extraction: Phase 1 and 2 trials evaluating the efficacy and safety of romidepsin were reviewed with a specific focus on its use in cutaneous T-cell lymphoma. All peer-reviewed articles with clinically relevant information were evaluated for inclusion. Data Synthesis: In advanced stage CTCL, single or combination chemotherapy regimen responses are variable and lack durability. Romidepsin is a histone deacetylase inhibitor approved for refractory cutaneous T-cell lymphoma, Romidepsin has shown an improvement in duration of response and pruritus over traditional therapy. In 2 independent Phase 2 trials, romidepsin showed an overall response rate of 34% and durable response of 13–15 months in patients with refractory CTCL. The most frequent toxicities of romidepsin include nausea. vomiting, fatigue, or myelosuppresston. Clinically insignificant QT interval changes have been observed but did not correlate with a decrease in left ventricular ejection fraction, or elevated laboratory markers of myocardial damage. Conclusions: Romidepsin is an effective, durable, and well-tolerated single-agent therapy in patients with refractory CTCL and should be considered for formulary addition in this population.

Abstract
Introduction: Cutaneous T cell lymphoma (CTCL) encompasses a heterogeneous group of neoplasms of skin-homing T cells, which includes mycosis fungoides, the most common form, and Sézary syndrome, the leukemia equivalent of mycosis fungoides. Histone deacetylase inhibitors are currently under investigation for their therapeutic value in a variety of conditions. Through multiple mechanisms, they induce apoptosis or inhibition of tumor cell growth. Some studies have also shown histone deacetylase inhibitors to have synergistic activity with existing therapeutic agents in selected conditions. Romidepsin is a histone deacetylase inhibitor with a promising efficacy and safety profile that may represent a valuable treatment alternative for patients with treatment-resistant mycosis fungoides and Sézary syndrome. Aims: To review emerging evidence regarding the use of romidepsin in the management of treatment-resistant CTCL. Evidence review: There is evidence that romidepsin can induce significant and durable responses in patients with refractory CTCL. In two independent Phase II trials including a total of 167 patients with CTCL, there was an overall response rate of 34% with a partial response of 28% and complete response rate of 6%. The most frequent toxicities reported from the Phase II trials were nausea, vomiting, fatigue, anorexia, and dysgeusia. Clinical potential: Romidepsin may be an effective therapeutic option for patients with CTCL who have had treatment failure with multiple standard treatment modalities.

Abstract
Mature T- and natural killer (NK)-cell neoplasms are relatively rare forms of leukemia/lymphoma. The diagnosis of these entities is often difficult, necessitating extensive immunophenotypic, molecular, and genetic testing. Despite the accumulating information on the pathobiology of these neoplasms, in many cases the prognosis remains poor. This article presents an updated view of the morphologic, immunophenotypic, genetic, and molecular characteristics of the mature T- and NK-cell neoplasms. For a better understanding of this complex topic, the development of normal T and NK cells is briefly discussed. The presentation of the characteristic features of the neoplasms in the 2008 World Health Organization classification of hematopoietic neoplasms includes advances in the understanding of the pathobiology of each diagnostic category.

Abstract
Mycosis fungoides (MF) constitutes the most frequent cutaneous T-cell lymphoma. Sezary syndrome is considered by some authors to be an erythrodermic leukemic variant of MF, but is classified separately in the new WHO-EORT classification of cutaneous lymphomas. MF usually occurs in old adults with a 2:1 male to female ratio. Its prognosis is variable and strongly conditioned by the extent and type of skin involvement and presence of extracutaneous disease. Patients with stage IA-disease have an excellent prognosis with an overall long-term life expectancy that is similar to an age-, sex-, and race-matched control population. Almost all patients with stage IA MF will die from causes other than MF, with a median survival >33 years. Only 9% of these patients will progress to more extended disease. Patients with stage IB or IIA have a median survival greater than 11 years. These patients with T2 disease have a likelihood of disease progression of 24% and nearly 20% die of MF. Subgroups with stage IB or IIA have similar prognosis. Patients with cutaneous tumors or generalized erythroderma have a median survival of 3 and 4.5 years, respectively. The majority of these patients will die of MF. Extracutaneous dissemination is observed in less than 10% of patients with patch or plaque disease and in 30-40% of patients with tumors or generalized erythrodermatous involvement. Extracutaneous involvement is directly correlated to the extent of cutaneous disease. The most commonly involved organs are lung, spleen, liver, and gastrointestinal tract. Patients with extracutaneous disease at presentation involving either lymph nodes or viscera have a median survival of <1.5 years. Patients with plaque-type or erythrodermic MF may develop cutaneous tumors with large cell histology, often expressing CD30, which share a common clonal origin as observed in their preexisting MF and are associated with a less favourable outcome.

Abstract
BACKGROUND Mycosis fungoides is an uncommon cutaneous T-cell lymphoma characterized by malignant monoclonal proliferation of T-helper lymphocytes. Its course is variable with a potential for lymphatic and hematogenous involvement. We report the investigations, staging, treatment, follow-up, and outcome of 28 patients. This is the first such study reported from Ireland. METHODS Twenty-eight patients with mycosis fungoides (14 women, 14 men; average age, 52.5 years) were reviewed over 12 years in the dermatology clinic which assesses an average of 4500 patients per year. All mycosis fungoides patients were referred from their family physicians. The diagnosis was made in all cases from a combination of clinical findings, histology, and immunohistochemistry. TNM staging revealed 11 patients at diagnosis stage IA (T1), 12 at stage IB (T2), four at stage IIB (T3), and one at stage III (T4). RESULTS The usual male preponderance was not found. Eight patients needed multiple biopsies to establish the diagnosis. Detailed investigations were not useful in the early stages. Patients were followed up over a 12-year period. Thirteen patients died as a result of cutaneous lymphoma. Two patients with stage IA disease progressed rapidly and died, a feature reported in only 10% of patients at this stage. Five patients showed unusual features, including a long history prior to presentation, the development of the rarely reported bullous mycosis fungoides, and aggressive disease beginning at a young age. CONCLUSIONS Mycosis fungoides is rare; we reviewed 28 patients over 12 years. The prognosis is poor at the later stages; 13 patients died. Two patients who died were unusual in that they rapidly progressed from stage IA disease; however, in the majority of patients with this stage, the prognosis is excellent. Detailed investigations were unhelpful in early stage disease. Close clinical follow-up is essential to identify disease progression.

Abstract
Adult T-cell leukemia/lymphoma (ATLL) is a malignant proliferation of mature helper T lymphocytes,(1) and is caused by human T-lymphotropic virus type I (HTLV-I);(2) an HTLV-I infection endemic in the Caribbean, south-western Japan, South America and Africa.(3,4) Seroepidemiological studies suggest that it is also endemic in Brazil.(5) Although carriers of HTLV-I show polyclonal integration of virus in T lymphocytes, only patients with ATLL of various subtypes show monoclonal integration of HTLV-I in tumor cells.(6,7) Cutaneous T-cell lymphomas (CTCL) are a group of primary cutaneous lymphoproliferative diseases(8) with unknown etiology.(9) The two most common presentations of CTCL are mycosis fungoides (MF) and Sézary syndrome (SS).(10-13) However, both CTCL categories can easily resemble ATLL. Therefore, in HTLV-I endemic areas, differentiation between ATLL and CTCL must be performed, as they have different prognoses and treatment approaches.(14).

Abstract
Os linfomas cutâneos de células T/NK constituem um grupo de doenças linfoproliferativas extranodais atualmente classificadas e subdivididas de acordo com o comportamento clínico segundo consenso da Organização Mundial de Saúde e da Organização Européia para Pesquisa e Tratamento do Câncer. Os linfomas cutâneos de células T/NK de comportamento clínico indolente compreendem a micose fungóide clássica, a micose fungóide foliculotrópica, a reticulose pagetóide, a cútis laxa granulomatosa, o linfoma cutâneo primário de grande célula anaplásica, a papulose linfomatóide, o linfoma subcutâneo de célula T paniculite-símile e o linfoma cutâneo primário de pequena e média célula T CD4+ pleomórfica. Os linfomas cutâneos de células T/NK de comportamento agressivo incluem a síndrome de Sézary, o linfoma extranodal de célula T/NK, tipo nasal, o linfoma cutâneo primário agressivo de célula T CD8+ epidermotrópica, o linfoma cutâneo de célula T <FONT FACE=Symbol>gd</FONT> e o linfoma cutâneo primário de célula T periférica, não especificado. O linfoma-leucemia de células T do adulto e a neoplasia hematodémica CD4+CD56+, embora considerados linfomas sistêmicos, são aqui abordados por apresentarem-se inicialmente na pele em significativo número de pacientes. O diagnóstico desses processos é realizado pelo exame histopatológico complementado pela análise do fenótipo das células neoplásicas, imprescindível no processo classificatório. O estadiamento para a avaliação da extensão anatômica da doença considera além do envolvimento cutâneo, o estado clínico e histológico dos linfonodos e das vísceras. Avaliação hematológica é fundamental na caracterização da síndrome de Sézary. Os tratamentos preconizados incluem terapêuticas dirigidas exclusivamente à pele, modificadores da resposta biológica e quimioterapia sistêmica.

Abstract
Patients with advanced cutaneous T cell lymphoma (CTCL) exhibit profound defects in cell-mediated immunity. Although it has been suggested that Sezary syndrome (SS) patients have a decreased natural killer (NK) lymphocyte activity, nothing has been reported concerning the sensitivity of Sezary cells to NK lymphocyte-mediated cytotoxicity. Peripheral blood NK cells from healthy donors were tested against Sezary tumoral cell lines as well as against freshly isolated Sezary cells. Further, we studied their ability to exhibit antibody -dependent cell-mediated cytotoxicity using either the murine anti-CD158k/KIR3DL2 monoclonal antibody (moAb) AZ158 that specifically recognizes Sezary cells, or the anti-CD52 monoclonal antibody alemtuzumab. The results show that Sezary cell lines are susceptible to NK lymphocyte lysis. More importantly, we found that freshly isolated malignant cells are killed either by IL-2 activated allogeneic NK lymphocytes or when the tumor lymphocyte targets are incubated with an anti-MHC class I F(ab)'2 antibody. Further, anti-KIR3DL2 and anti-CD52 moAb can enhance the NK lysis. Finally, we report that NK lymphocytes isolated from SS patients are potentially cytotoxic lymphocytes against autologous malignant Sezary cells. These findings indicate that antitumor-mediated NK lymphocyte cytotoxic activity can be triggered in patients with CTCL and raise the possibility of developing novel therapeutic strategies by stimulating their innate immunity.

Abstract
Exfoliative erythroderma, or diffuse erythema and scaling of the skin, may be the morphologic presentation of a variety of cutaneous and systemic diseases. Establishing the diagnosis of the underlying disease is often difficult and, not uncommonly, erythroderma is classified as idiopathic. Several cases are presented to demonstrate the diversity of presentation of this disease. Laboratory findings are typically unhelpful in establishing the etiology of erythroderma. Clinical data combined with multiple skin biopsies over time are necessary. Systemic complications of erythroderma include infection, fluid and electrolyte imbalances, thermoregulatory disturbance, high output cardiac failure, and acute respiratory distress syndrome. The initial approach to the management of erythroderma of any etiology includes attention to nutrition, fluid and electrolyte replacement, and the institution of gentle local skin care measures. Oatmeal baths and wet dressings to weeping or crusted sites should be followed by application of bland emollients and low-potency topical corticosteroids. Systemic dermatologic therapy may be required to maintain improvement achieved with local measures or to control erythroderma refractory to local measures. The prognosis of erythroderma is dependent on the underlying etiology.

Abstract
PRESENTING FEATURES: An 85-year-old black woman presented to the Osler Medical Service complaining of a pruritic, erythematous scaly rash that was on her right thigh and abdomen and that had been worsening over the prior 3 months. She also complained of increasing fatigue, decreased exercise tolerance, and a 5-lbs weight loss. There was no orthopnea, paroxysmal nocturnal dyspnea, fevers, chills, or night sweats. She denied recent travel and exposures to or contact with ill people. Her past medical history was unremarkable. There was no history of eczema, atopy, or dermatologic conditions. Her only medication was a baby aspirin taken daily. On physical examination, she was afebrile, her blood pressure was 110/72 mm Hg, and her pulse was 82 beats per minute with a room air oxygen saturation 98%. She was mildly obese but in no apparent distress. She had 1-cm anterior cervical lymphadenopathy bilaterally and a 1-cm left axillary lymph node. Cardiovascular and chest examination was unremarkable. Her abdomen was soft and nontender, with a faint, erythematous rash that was mildly scaly but nontender in her abdominal skin fold. Her right thigh showed a large erythematous area, approximately 15 x 20 cm, which was scaly with multiple areas of discoloration (Figure 1). There was no palpable mass. She had slight edema in her right leg. Her left thigh was normal. Neurologic examination was nonfocal. Laboratory studies were notable for a white blood cell count of 17,000 cells/microL, with a differential of 46% lymphocytes. The absolute lymphocyte count was 8000 cells/microL. Hematocrit was 28%. Platelet count was normal. A comprehensive metabolic panel was normal. A peripheral blood smear (Figure 2) showed numerous atypical lymphocytes with cerebriform nuclei. Peripheral blood flow cytometry showed the presence of a clonal population of T cells that expressed CD4 and CD5 but showed a loss of CD7. What is the diagnosis?

Abstract
Cutaneous lymphomas are rare and, although some are a manifestation of systemic lymphoma, the majority arise primarily from the skin. These primary cutaneous lymphomas comprise both T- and B-cell subtypes and represent a wide spectrum of disorders, which at times can be difficult to diagnose and classify. Classical therapeutic strategies include topical corticosteroids, phototherapy, radiotherapy, retinoids, extracorporeal photopheresis, topical chemotherapy, systemic chemotherapy and biological response modifiers. Newer therapies include the synthetic retinoid bexarotene, the immunotoxin conjugate denileukin diftitox, interleukin-12 and monoclonal antibodies such as alemtuzumab and rituximab.

Abstract
OBJECTIVES Alemtuzumab (anti-CD52, Campath-1H) has recently been shown to be effective in the treatment of a range of hematological malignancies, including B-cell chronic lymphocytic leukemia and T-cell prolymphocytic leukemia. We undertook a phase II study to evaluate the safety, tolerability and efficacy of alemtuzumab in patients with relapsed or refractory advanced stage cutaneous T-cell lymphoma. PATIENTS AND METHODS A total of eight patients were enrolled, seven with mycosis fungoides/Sézary syndrome (MF/SS) and one with large-cell transformation of MF. Seven patients had disease refractory to multiple previous therapies. Alemzumab (30 mg) was administered intravenously three times per week for 12 wk or until maximum response. RESULTS The overall response rate was 38%, with three patients achieving partial remission, two patients with stable disease and three patients with progressive disease (PD) during treatment. The time to progression was short, with all patients developing PD within 4 months of starting alemtuzumab. Response duration in the three PR patients was also brief, with responses lasting less than 3 months in all three cases. Significant hematological and immunosuppressive toxicity was observed, with both grade 3-4 cytopenias and significant infectious complications occurring in a majority of cases. CONCLUSIONS Our findings suggest that in heavily pretreated, refractory, advanced stage MF/SS, although alemtuzumab has biological activity, it is associated with significant toxicity and only modest clinical utility. As such, combination regimens incorporating alemtuzumab merit further investigation in this difficult to treat patient group.

Abstract
Cutaneous T-cell lymphoma (CTCL) is a neoplasm of helper T cells whose first manifestations usually appear in the skin. The various forms of CTCL are distinguished by both clinical features and histopathology. Early on, the diagnosis may be difficult to establish because of its numerous, and often non-specific, clinical presentations. Further, the pathological findings of early lesions may lack the diagnostic features observed in well-developed or advanced disease. The diagnosis of CTCL must be considered in any patient with a chronic, therapy-resistant condition of the skin. In patients with non-specific histological findings, a high index of suspicion and multiple biopsies may eventually lead to a diagnosis of CTCL. Once the diagnosis of CTCL is established, accurate staging is essential both for its effect on treatment decisions and for its prognostic value. In general, CTCL is a chronic, slowly progressive disease with a long evolution. The development of tumours is a poor prognostic sign, as is erythroderma. The Sezary syndrome is a distinct form of erythrodermic CTCL that is characterized by exfoliative erythroderma, lymphadenopathy, lymphocytosis, intense pruritus, and circulating large, abnormal lymphocytes (Sezary cells). When death does occur, it is most often due to septicemia. Treatment of CTCL must be tailored to the individual patient. The most commonly employed treatment options are photochemotherapy and topical chemotherapy.

Abstract
We describe a patient with therapy-resistant cutaneous T-cell lymphoma, Sézary syndrome variant, in association with concurrent polyarthritis and vitiligo, who was successfully treated with extracorporeal photochemotherapy (ECP). The combination of Sézary syndrome with seronegative rheumatoid arthritis is rare. In our patient the T-cell lymphoma was refractory to standard treatments that included psoralen-UVA, lymph node irradiation, and polychemotherapy. ECP has been shown to be effective in the treatment of selected cases of Sézary syndrome. There is a strong suggestion that ECP as a monotherapy can provide a significant benefit for other T-cell-mediated diseases including rheumatoid arthritis. In spite of a disease duration of 10 years, a very low CD8 cell count (2% of lymphocytes), a very high CD4 cell count (94%), and multiple unsuccessful chemotherapeutic trials before initiation of ECP, our patient achieved a long-lasting complete remission of both diseases with normalization of the CD4+ and CD8+ T-lymphocyte subsets. Concurrent developing vitiligo was unaffected by ECP.

Abstract
Cutaneous lymphomas are rare and although some are a manifestation of systemic lymphoma, the majority arise primarily from the skin. These primary cutaneous lymphomas comprise predominantly T cell subtypes and represent a wide spectrum of disorders. Pathologists can currently choose to label these conditions according to three classifications (REAL, EORTC or WHO) but each has shortcomings. Nonetheless, in an attempt to unify the field, we would recommend that pathologists make every attempt to categorise these conditions according to the WHO classification. This classification can encompass all the conditions and aligns the cutaneous lymphomas with the broader systemic lymphoproliferative conditions.

Abstract
BACKGROUND Cutaneous T-cell lymphoma (CTCL) is a clonally derived, skin-invasive malignancy of CD4(+) T lymphocytes with the phenotype of mature helper T cells. Advancing stages of CTCL are associated with depressed cell-mediated immunity, increased production of T helper type 2 cytokines and decreased levels of T helper type 1 cytokines. OBJECTIVE Our purpose was to evaluate the cytokine secretion pattern and cell-mediated cytotoxicity in peripheral blood mononuclear cells of patients with Sézary syndrome in relation to the presence of the malignant clone. METHODS Serial polymerase chain reaction for the T-cell receptor-beta or T-cell receptor-gamma gene rearrangement was used to determine the presence of the malignant clone. Enzyme-linked immunosorbent assays were used to determine the levels of interleukin 4 and interferon gamma produced by the peripheral blood mononuclear cells from the patients with Sézary syndrome. RESULTS We demonstrate 3 cases of Sézary syndrome with typically suppressed cell-mediated cytotoxicity, elevated production of interleukin 4, and depressed production of interferon gamma by their peripheral blood mononuclear cells before institution of therapy with biologic response modifier therapy. In all 3 cases after clinical and molecular remission, we observed striking immunologic changes, including an increase in levels of natural killer cell activity and interferon gamma production and decreased production of interleukin 4. CONCLUSIONS The observation that the cytokine secretion pattern by peripheral blood mononuclear cells from 3 patients with Sézary syndrome normalized with the disappearance of the malignant clone from the peripheral blood suggests that the malignant T cells account for the aberrant cytokine production. Moreover, the aberrant cytokine production may be the cause for suppression of cell-mediated immunity seen in advancing stages of CTCL.

Abstract
BACKGROUND Cutaneous T-cell lymphoma (CTCL) is a rare occurrence in India. Total skin electron irradiation (TSEI) is a well-accepted therapeutic modality for the treatment of CTCL throughout the world. The aim of this study was to retrospectively analyze the treatment outcome of TSEI in Indian patients with CTCL and to determine the different parameters affecting the disease-free survival in these patients. METHODS Fourteen male patients between 27 and 82 years of age with CTCL (duration of disease, 4 months to 2 years) were treated with TSEI between 1985 and 1998. Seven patients had early stage disease, while the other seven had advanced disease. Two patients had lymph node involvement at the time of presentation. The TSEI was performed according to the Stanford technique delivering a total dose in the range 8-36 Gy. RESULTS Of the 14 patients, 10 showed complete remission following TSEI. The total follow-up period was 4-110 months (median, 52 months). Five patients were disease free at the end of 5 years. Two patients died due to rapid progression of the disease, while the cutaneous lesions relapsed in three patients after 2-27 months and one patient developed visceral metastasis. CONCLUSIONS TSEI was an effective therapeutic modality for the treatment of CTCL in this group of patients, both as a curative and palliative measure, although the long-term prognosis is poor.

Abstract
Primary cutaneous lymphomas have a distinct clinical behavior and prognosis, and therefore require a different therapeutic approach, as compared with their primary nodal equivalents. The European Organization for Research and Treatment of Cancer (EORTC) classification for primary cutaneous lymphomas recognizes a limited number of cutaneous T-cell lymphomas and cutaneous B-cell lymphomas and is at present the best guide to optimal management and treatment of these conditions. Herein, the relationship between the EORTC classification and the recently published World Health Organization classification is discussed, and recent developments regarding the main types of cutaneous T-cell lymphomas and cutaneous B-cell lymphomas recognized in the EORTC classification are presented.

Abstract
PURPOSE Primary cutaneous T-cell lymphomas (CTCLs) encompass a wide variety of lymphomas that are characterized by the localization of the malignant lymphocytes to the skin at presentation. Advances in molecular biologic techniques, including immunophenotyping and gene rearrangement studies to determine clonality, have led to more frequent diagnosis of CTCL as well as more consistent subclassification of these entities. However, there continues to be confusion in the classification, prognosis, and management of patients with CTCL. The purpose of this review is to present a summary of the diagnosis, prognosis, and treatment of CTCL, with specific emphasis on mycosis fungoides (MF) and Sézary syndrome (SS). We also present a detailed discussion of the entities that make up the differential diagnosis of CTCL. DESIGN We reviewed the medical literature on CTCL and other diseases that make up the differential diagnosis of CTCL. RESULTS AND CONCLUSION MF and SS are the most common forms of CTCL. The etiology of this disease is still unknown. Patients may go for months to years with skin abnormalities before being diagnosed. MF/SS is an indolent disease and patients with T1 disease have a normal life expectancy. Patients who undergo transformation to large-cell lymphoma (8% to 23% of patients) have a poor prognosis, with mean survival ranging from 2 to 19 months. Treatment for MF/SS continues to be palliative. There are many new therapies that are currently being investigated in clinical trials, and the DAB(389)IL-2 fusion protein was recently approved for the treatment of refractory MF/SS.

Abstract
BACKGROUND Generalized eczema or erythroderma may be the presenting sign of cutaneous T-cell lymphoma. Additionally, intractable pruritus has been associated with Hodgkin's lymphoma. However, reports of adult-onset eczematous dermatitis has rarely been linked to noncutaneous lymphoproliferative disorders. OBSERVATIONS We observed one patient in 1993 who had the onset of intractable dermatitis characterized by prurigo nodularis-like lesions and widespread erythematous plaques. After 18 months of cutaneous symptoms he experienced dyspnea. At this time Hodgkin's disease was diagnosed. This observation prompted us to evaluate subsequent patients with adult-onset eczema who were poorly responsive to therapy and in whom an obvious cause could not be determined. Over the next 24 months we identified an additional 2 patients with lymphoma who met this criteria. CONCLUSION Unexplained eczema of adult onset may be associated with an underlying lymphoproliferative malignancy. When a readily identifiable cause (eg, contactants, drugs, or atopy) is not found, a systematic evaluation should be pursued. Patients should be evaluated with a careful physical examination, complete blood cell counts, peripheral blood smears, chest roentgenography, computed tomography of the chest and abdomen, and serum protein electrophoresis.

BACKGROUND Erythrodermic cutaneous T-cell lymphomas (CTCL) including Sézary syndrome have been successfully treated with daily administration of chlorambucil and prednisone (Winkelmann regimen). OBJECTIVES Our purpose was to determine the efficacy and safety of a low-dose pulse chemotherapy with chlorambucil and fluocortolone in this stage of the disease. Fluocortolone has the same potency as prednisone but lacks a mineralocorticoid effect. PATIENTS/METHODS Thirteen patients with erythrodermic CTCL (stages III-IVb) were treated with chlorambucil and fluocortolone therapy (chlorambucil 10-12 mg day-1 for 3 days and fluocortolone, first day 75 mg, second day 50 mg and third day 25 mg) as primary therapy in an uncontrolled pilot study. Treatment was started with pulses every 2 weeks; subsequently, the intervals were prolonged according to the clinical status. Clinical outcome, side-effects and long-term survival were assessed. RESULTS Seven patients achieved a complete remission and six had a partial response (improved significantly). The mean duration of remissions was 16.5 (median 12) months. The mean number of cycles necessary during the first year was one cycle every 5 weeks. No treatment-related severe side-effects occurred. The long-term follow-up (mean 31.5, median 27 months) showed that six patients remained in complete remission and three showed a stable partial remission. Four patients died, two of them from their lymphoma. CONCLUSIONS We conclude that pulse chemotherapy with chlorambucil and fluocortolone is effective and safe in the treatment of erythrodermic CTCL and should be considered as an alternative to the classical Winkelmann treatment scheme.

Abstract
Erythroderma can be caused by a variety of underlying dermatoses, infections, and systemic diseases. Many of the findings on history, physical examination, and laboratory evaluation are nondiagnostic. Distinctive clinical and laboratory features pointing to a specific disease may be evident, however. Conclusive clinicopathologic correlation may require multiple and repeated skin biopsies. The prognosis of erythroderma has improved with the advent of innovative dermatologic therapies (e.g., cyclosporine and synthetic retinoids) and advances in the management of systemic manifestations. Death from sepsis, cardiac failure, adult respiratory distress syndrome, and capillary leak syndrome continue to be rarely reported. A high index of suspicion for these complications must be maintained to facilitate early medical intervention.

Abstract
Stage IV cutaneous T-cell lymphoma (CTCL) has a notoriously poor prognosis and many treatment options exist. We describe the successful treatment of a case of stage IV CTCL with combination photopheresis and high-dose interferon alfa (IFNalpha). The patient was treated with combination therapy of monthly photopheresis and daily doses of IFNalpha up to 36 MU. Response to therapy was followed by clinical observation and Southern blot analysis for the detection of a malignant clone. The findings of this case were compared with others using a computer-based literature review. A complete clinical response lasting 64 months was achieved. Clinical relapse was preceded by an increase in the CD4/CD8 ratio and by reappearance of the T-cell receptor gene rearrangement. Combined photopheresis and high-dose IFNalpha led to a durable and sustained complete response in stage IV CTCL. CD4/CD8 ratios and T-cell gene rearrangements may be helpful in patient management.

Abstract
Cutaneous T-cell lymphoma (CTCL) is an indolent lymphoma usually of CD4+ T lymphocytes in which the aggressive treatment for the advanced stages does not increase survival. Photopheresis has been established as an alternative modality for the therapy of erythrodermic CTCL and reportedly improves survival in patients with advanced stages of the disease. The objective of this study is to review the experience of treating patients with erythrodermic CTCL with extracorporeal photochemotherapy (ECP) at the New York Veteran Affairs Medical Center/NYU Medical Center between September 1987 and April 1997. Forty-one patients with erythrodermic CTCL (stages III and IV) received photopheresis; 25 of them fulfilled the inclusion criterion, i.e., the completion of greater than or equal to 6 cycles of photopheresis. Skin score was defined as a product of severity and percentage of involved surface area. Complete clinical response was defined as disappearance of measurable disease for at least one month, and partial response was defined as greater than or equal to 50% clearance of measurable disease for at least one month. The profile of the patients was: 20 men, 5 women; average age: 64.2 years; 17 patients had stage III disease, and 8 had stage IV disease. Five of the 25 patients (20%) achieved complete clinical response, another 15 (60%) had partial response, and 5 (20%) had no response. The mean time (+/- SD) to achieve complete clinical clearance was 12.6 +/- 10 months (range: 4-30 months) and the mean time (+/- SD) to obtain partial clinical response, including complete response, was 9.7 +/- 5.3 months (range: 4-17 months). Remission duration ranged from 9 to 67 months. The median survival time from the time of initiation of photopheresis is estimated at 70 months. The complete responder group had a lower median CD4/CD8 ratio compared to the non-responders at baseline (3.8 vs 7.2, respectively), although the difference was not statistically significant (P = 0.40). At the time of maximal response, the CD4/CD8 ratio of the complete responder group decreased towards normal values (median = 1.2), whereas this ratio increased among the non-responders (median = 11.0; P = 0.04). Side effects were minimal. Extracorporeal photochemotherapy is an effective and safe treatment for erythrodermic CTCL. In some of these patients, it can induce a long-term and complete clinical remission.

Abstract
Pre-Sézary syndrome is an erythroderma with a chronic course, clinical findings of Sézary syndrome, lymphocytic subepidermal band infiltration at times, and repeated cycles of circulating Sézary cells of less than 1,000 cells/mm3. Duration of the pre-existing skin diseases preceding pre-Sézary erythroderma varies from a few weeks to 20 years. Before the erythroderma develops, these patients are diagnosed with contact dermatitis, neurodermatitis, chronic dermatitis, atopic dermatitis, or asteatotic eczema. Hand lesion also precedes the pre-Sézary erythroderma. This condition has been controlled by three cycles of chemotherapy consisting of vincristine, cytoxan, doxorubicin, and prednisolone. We describe a case of pre-Sézary syndrome preceded by hand lesion and treated with chemotherapy.

Abstract
OBJECTIVE To determine the frequency of ophthalmic abnormalities in patients with cutaneous T-cell lymphoma (mycosis fungoides and Sézary syndrome) and T-cell lymphoma involving the skin and to describe the clinical course of the disease with selected examples. DESIGN Retrospective, clinic-based, cross-sectional study. PARTICIPANTS A computerized diagnostic retrieval system was used to identify all patients with T-cell lymphoma involving the skin who were examined at the Mayo Clinic (Rochester, Minnesota) between January 1, 1976 and December 31, 1990. The medical records of affected patients were reviewed. MAIN OUTCOME MEASURES Identification of ophthalmic abnormalities. RESULTS During the 15-year interval from 1976 through 1990, cutaneous T-cell lymphoma was diagnosed in 2155 patients. Of these, 42 (1.95%; 26 male and 16 female) had at least one ophthalmic abnormality attributable to the disease. The diagnoses in these 42 patients were mycosis fungoides in 19, clinical variants of T-cell lymphoma of the skin (most commonly peripheral T-cell lymphoma) in 11, and Sézary syndrome in 12. Cicatricial eyelid ectropion was the most common finding, affecting 17 (40.4%) of the 42 patients. Thirty-seven patients had findings that, although probably not a direct consequence of cutaneous T-cell lymphoma, have been cataloged in previous studies. CONCLUSION Although ophthalmic abnormalities in patients with cutaneous T-cell lymphoma are relatively uncommon, the manifestations of the disease are diverse and frequently difficult to treat.

Abstract
BACKGROUND There is limited published evidence regarding the efficacy of total skin electron beam radiation for patients with the diffuse erythrodermic form of mycosis fungoides. METHODS Forty-five patients with erythrodermic mycosis fungoides were managed at McMaster University in Hamilton, Ontario, Canada (n=34), and at Yale University (n=11) between 1970 and 1996. All received radiation without neoadjuvant, concomitant, or adjuvant therapies. The median age was 67 years (range, 42-84 years). The male-to-female ratio was 2.2. Fifteen received radiation for the treatment of newly diagnosed disease. There were 28 with Stage III (T4 N0-1 M0), 13 with Stage IVA (T4 N2-3 M0), and 4 with Stage IVB (T4 N0-3 M1) disease, and 21 had blood involvement. The median radiation dose was 32 gray (Gy) (range, 4.8-40 Gy). The median treatment time was 21 days (range, 3-125 days). A technically more intense method of radiation (32-40 Gy and 4-6 MeV electrons) was administered to 23 patients. RESULTS All patients responded. The rate of complete cutaneous remission was 60%, with 26% remaining progression free at 5 years. Remission was associated with more intense radiation (P=0.014 in multivariate analysis with adjustment for blood and staging information). With the more intense radiation, 74% attained remission, with 36% remaining progression free at 5 years. For 8 patients with Stage III disease without blood involvement, all entered remission, with 69% remaining progression free at 5 years. Twenty of 30 deaths were related to mycosis fungoides. The median overall survival was 3.4 years, with a 10-year estimate of 28%. The median cause specific survival was 5 years, with a 10-year estimate of 43%. Both overall and cause specific survival were associated with an absence of blood involvement (both P<0.03 in multivariate analysis). Age was not a significant factor. Toxicities of radiation were acceptable when radiation was administered over 6-9 weeks at 5 fractions per week. CONCLUSIONS Total skin radiation is an efficient monotherapy for patients with erythrodermic mycosis fungoides. With more intense radiation, the rate of cutaneous remission is 74%, and 27% remain progression free at 10 years. Radiation may be most efficacious in Stage III, with no blood involvement. When there is blood, lymph node, or visceral involvement, combined modality therapies should be explored.

Abstract
Photopheresis or extracorporeal photochemotherapy (ECP) is a novel immunomodulatory therapy based upon pheresis of light-sensitive cells. Whole blood is removed from patients who have previously ingested the photosensitizing agent 8-methoxypsoralen (8-MOP) followed by leukapheresis and exposure of the 8-MOP containing white blood cells (WBCs) extracorporeally to an ultraviolet A (UVA) light source prior to their return to the patient. In 1988, the Food and Drug Administration (FDA) approved photopheresis for the treatment of cutaneous T-cell lymphoma (CTCL). Treatment of CTCL with photopheresis has been reported in over 300 patients worldwide. Photopheresis has also demonstrated encouraging results in the treatment of solid organ transplant rejection, graft versus host disease, scleroderma, and other autoimmune diseases although fewer patients have been studied. This review will focus on the North American experience with photopheresis.

Abstract
Mycosis fungoides (MF) and Sezary syndrome (SS) are the two main clinical entities of cutaneous T-cell lymphoma (CTCL). As the disease progresses from MF to SS, a switch from a type 1 (interleukin [IL]-2 and gamma interferon [IFN-gamma]) to a type 2 (IL-4) cytokine production profile occurs. Although roles for type 1 and type 2 cytokines in the pathogenesis of CTCL have been proposed, the cellular origins of these cytokines are unclear. Using flow cytometry to identify individual T-cell subsets, we studied cytokine synthesis by the T cells of 13 patients with SS and 12 with MF and 9 hematologically healthy donors. Upon activation with phorbol 12-myristate 13-acetate (PMA), the numbers of T cells synthesizing IL-2 were similar for all study groups. Whereas the predominant T-cell producing IL-2 in healthy donors and in those with MF was CD7(+), in patients with SS, it was CD7(-). Although the number of IL-4(+) CD4(+) T cells was low for all study groups, there was a significantly higher number of IL-4(+) CD8(+) T cells in patients with MF than in those with SS or healthy donors. There was a decline in the number of IFN-gamma-producing T cells in CTCL donors compared to that in healthy donors. More importantly, there was a significant decrease in the number of IFN-gamma-producing T cells with disease progression from MF to SS. The inability of these T cells to synthesize IFN-gamma may have prognostic value in CTCL, since it may be responsible for the progression of the disease from MF to SS.

Abstract
OBJECTIVES To describe the current state of the knowledge regarding the pathology, clinical presentation, treatment strategies, and nursing management of patients with cutaneous T-cell lymphoma, specifically, mycosis fungoides and the Sezary syndrome. DATA SOURCES Book chapters, review articles, published research studies, proceedings from professional meetings. CONCLUSIONS Although mycosis fungoides and the Sezary syndrome are rare, epidemiologic studies suggest an increasing incidence. Advances in cellular biology and immunology result in continuously changing diagnostic and treatment strategies aimed at this illness. IMPLICATIONS FOR NURSING PRACTICE Oncology nurses need an understanding of the current state of the knowledge of cutaneous T-cell lymphoma to meet the extensive needs of patients confronted with this chronic, progressively devastating malignancy.
