Abstract
Mycosis fungoides is a rare cutaneous lymphoma in the paediatric population. The aim of this study was to examine the epidemiological, clinical, and histological characteristics, as well as the treatment modalities and response to therapy of paediatric patients with mycosis fungoides. This retrospective cohort study reviewed the records of 37 paediatric patients treated at Rambam Medical Center, Israel, between 2013 and 2021. Extracted data included epidemiology, clinical presentation, histological reports, infiltrate clonality status, treatment modalities and response to therapy. The mean follow-up period was 60 months. All patients were diagnosed with stage IA or IB disease. Folliculotropic mycosis fungoides was the most prevalent variant (49%). Most patients were treated with phototherapy (90%), with a response rate of 85%, and a complete response rate of 55% after the first course. There were no significant differences in response to phototherapy between the folliculotropic or other variants (p = 0.072). Similarly, delayed diagnosis, atopic diathesis, clonality, phototherapy type or number of treatments, were not associated with response to therapy, while protracted phototherapy was associated with prolonged remission. In conclusion, mycosis fungoides in the paediatric population is an indolent disease with a favourable prognosis and potentially prolonged response to phototherapy.

Suggested Guidelines for the Treatment of Mycosis Fungoides in Countries with Limited Resources. Dermatol Res Pract 2023; 2023:1360740. [PMID: 36762366 PMCID: PMC9904957 DOI: 10.1155/2023/1360740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 01/13/2023] [Accepted: 01/17/2023] [Indexed: 02/04/2023] Open
Abstract
The treatment options for mycosis fungoides (MF) have been expanding but unfortunately many of the currently used treatment modalities are unavailable in Egypt and other African/Arab countries. In addition, there is a lack of consensus on the treatment of hypopigmented MF (HMF), which is a frequently encountered variant in our population. We aimed to develop regional treatment guidelines based on the international guidelines but modified to encompass the restricted treatment availability and our institutional experience. Special attention was also given to studies conducted on patients with skin phototype (III-IV). Treatment algorithm was formulated at Ain-Shams cutaneous lymphoma clinic through the collaboration of dermatologists, haematologists, and oncologists. Level of evidence is specified for each treatment option. For HMF, phototherapy is recommended as a first line treatment, while low-dose methotrexate is considered a second line. For early classical MF, we recommend Psoralen-ultraviolet A (PUVA), which is a well-tolerated treatment option in dark phenotype. Addition of either retinoic acid receptor (RAR) agonist and/or methotrexate is recommended as a second line. Total skin electron beam (TSEB) is considered a third-line option. For advanced stage, PUVA plus RAR agonist and/or methotrexate is recommended as first line, TSEB or monochemotherapy is considered a second line option. Polychemotherapy is regarded as a final option. All patients with complete response (CR) enter a maintenance and follow-up schedule. We suggest a practical algorithm for the treatment of MF for patients with dark phenotype living in countries with limited resources.

Abstract
Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma. However, it is rare in pediatric population. Most of the cases of pediatric MF present with hypopigmented patches and/or various other forms, which may often mimic common childhood dermatoses, thereby causing a delay in the diagnosis. There are no established treatment guidelines for pediatric MF. As the progression of childhood MF is extremely rare and it has an indolent course, it is usually diagnosed at an early stage (IA, IB, IIA), and hence phototherapy with a response rate of >80% is a well-established effective treatment in children. However, as recurrences are frequently seen on stopping the therapies, a maintenance regimen and long-term follow-up is equally important. This article reviews the epidemiological factors, clinical presentations, diagnosis, and various treatment modalities used in pediatric MF. We analyzed and compared the data of almost 616 childhood MF cases from various studies undertaken from 1988 to 2021.

Abstract
BACKGROUND Mycosis fungoides (MF) in children is a rare disease and there are limited data regarding the behavior of the disease in this age group. We aimed to collect additional data to better understand the clinicopathologic features of MF in children. MATERIALS AND METHODS This study was a retrospective analysis of pediatric MF patients (diagnosed at age 0 to 18 y). RESULTS Thirteen pediatric patients with MF were identified. Female predominance was observed with a ratio of 1.6:1. Median values for age of onset of skin lesions and age at the time of histologic diagnosis were 5 and 12 years, respectively. All patients had early stage (stage IA to IIA) of MF at the time of diagnosis. Hypopigmented MF comprised 77% of all study patients, followed by classic MF (15%) and pagetoid reticulosis (8%). The lower extremity (especially proximal leg) followed by trunk and upper extremity were most commonly affected sites. Seven of 9 patients who had available immunohistochemistry data showed CD8 + predominance. Five of 8 patients whose follow-up data was available, achieved complete response with narrowband ultraviolet B treatment, while 2 and 1 had near complete response and partial response, respectively. CONCLUSIONS Our study demonstrated female sex and CD8 + profile predominance. Hypopigmented MF constituted the majority of cases. We observed good responses with narrowband ultraviolet B treatment.

Abstract
BACKGROUND Cutaneous hematologic malignancies are rare in children, and the literature about them is still sparse. OBJECTIVE The purpose of our study was to report our experience with pediatric cases of cutaneous hematologic disorders and describe their clinical and histological features. METHODS Data were retrospectively collected from the histopathologic database of the CHU Sainte-Justine, University of Montreal, Montreal, Canada. All patients up to 18 years of age with a diagnosis of a primary cutaneous lymphoma (including lymphomatoid papulosis), secondary cutaneous lymphoma or cutaneous manifestations of leukemia, followed from 1980 to 2019 at our center were reviewed. RESULTS Thirty-six patients were included. Age at presentation ranged from birth to 18 years of age (mean 7.83 ± 5.16; median 7.0). Ten different hematologic disorders were identified according to the WHO-EORTC classifications: lymphomatoid papulosis (10 cases), mycosis fungoides (6 cases), anaplastic large cell lymphoma (4 cases), pre-B acute lymphoid leukemia (5 cases), primary cutaneous marginal zone B-cell lymphoma (4 cases), primary cutaneous CD4+medium T-cell lymphoproliferative disorder (1 case), extranodal NK/T-cell lymphoma (1 case), hydroa vacciniforme-like lymphoproliferative disorder (1 case), B-cell lymphoblastic lymphoma (1 case) and acute myeloid leukemia (3 cases). CONCLUSION The most common subtype of cutaneous hematologic disease in our single institution study was lymphomatoid papulosis (type A and type C), followed by mycosis fungoides. Recognition of this large clinical and histological spectrum by dermatologists is important because diagnosis is often established by biopsy of skin lesions, even in secondary cutaneous cases. Moreover, the clinicopathological correlation is of utmost importance for the final diagnosis of those pathologies.

Abstract
BACKGROUND The literature on pediatric mycosis fungoides (MF) and especially its folliculotropic variant (FMF) is sparse. OBJECTIVES To describe the clinical manifestations, treatments, outcomes and long-term course of pediatric MF, including FMF. METHODS A retrospective analysis was conducted of all consecutive MF patients diagnosed at ≤18 years attending two medical centers in 1995-2015. RESULTS The cohort included 71 patients, all but 2 of whom had early-stage disease: hypopigmented (55%) folliculotropic (42%) and classical MF (39%), alone or in combination. The head and neck area was involved in 43% of patients with early-stage FMF compared to 12% of the non-FMF group (p=0.004). There was no difference in the involvement of other body areas between the groups. Pruritus, although mild, was more often recorded among patients with early-stage FMF compared to non-FMF (58% vs. 29%, respectively, P=0.02). Complete response (CR) was achieved in 60 of the 69 patients with early-stage MF (87%) after an average of 1.8 treatment modalities. NBUVB was the most administered treatment to non-FMF patients with CR rates of 63% versus 29% of FMF patients (P=0.04). Systemic/bath PUVA, or UVA+NBUVB were the most administered treatments to FMF patients with CR rates of 60% versus 81% for non-FMF patients (P=0.17). During a mean follow-up of 9.2 years (range 1-24), stage progression was observed in 4 (6%) of the patients with early-stage disease, 2 of whom (all FMF) to advanced stage. CONCLUSIONS Pediatric MF presents as an early-stage disease with over-representation of hypopigmented and FMF variants. NBUVB and UVA-based therapies yield good response rates in non-FMF and FMF patients, respectively. Disease course is indolent, and even on relatively long follow-up, it has a very low progression rate from early to advanced-stage disease, occurring in patients with FMF. We propose a treatment algorithm for pediatric MF.

Abstract
BACKGROUND/OBJECTIVES Primary cutaneous lymphomas are rare in pediatric patients. The clinical and histopathological manifestations may differ from those in adults. Due to their low frequency and the insidious clinical picture, the diagnosis is usually delayed. The Spanish Primary Cutaneous Lymphoma Registry was initiated in 2016 as a multicenter registry that would allow better insight into the epidemiological, clinical, histopathological, and treatment response characteristics of patients with primary cutaneous lymphomas. METHODS We conducted a prospective observational cohort study of primary cutaneous lymphomas in pediatric patients participating in the Spanish Academy of Dermatology and Venereology (AEDV) Primary Cutaneous Lymphoma Registry. RESULTS At the time of the analysis, 10 patients under 18 years of age out of 799 all-age cases (1.25%) had been included in the registry (7 males, 3 females). The mean age at diagnosis was 9.7 years (SD: 4.8). Seven (70%) had mycosis fungoides, 2 of them had the folliculotropic variant; and 3 (30%) had primary cutaneous marginal zone B-cell lymphoma. CONCLUSIONS Primary cutaneous lymphomas are extremely rare in pediatric patients and usually have a good prognosis. Therefore, a high level of suspicion is necessary for the diagnosis. We suggest management by experienced physicians and follow-up into adulthood.

Abstract
Primary cutaneous lymphomas are extranodal non-Hodgkin lymphomas of T- or B- cell origin, that predominantly affect older patients but have been reported in all age groups and as early as in the first years of life. Diagnosis of cutaneous lymphomas is challenging and requires high clinical suspicion and close collaboration between dermatologists, pediatric oncologists and pathologists. Skin involvement of non-Hodgkin lymphomas in children or adolescents can either be primary cutaneous or secondary due to an underlying nodal lymphoma. The most common primary cutaneous lymphomas encountered in children are of T-cell origin, with mycosis fungoides being the most prevalent cutaneous T-cell lymphoma, followed by CD30+ lymphoproliferative disorders. While cutaneous lymphomas share clinicopathologic characteristics between juvenile and adult forms, there are important differences in terms of clinical presentation, diagnosis and treatment. The hypopigmented variant of mycosis fungoides seems to be overrepresented in the pediatric age group. Prognosis and treatment of mycosis fungoides are stage dependent. The majority of children present with early-stage disease and respond well to topical corticosteroids and phototherapy.

Abstract
Primär kutane Lymphome sind extranodale T- oder B-Zell-Non-Hodgkin-Lymphome, die vorwiegend ältere Patienten betreffen, aber in allen Altersgruppen einschließlich der ersten Lebensjahre auftreten können. Die Diagnose kutaner Lymphome ist eine Herausforderung und erfordert einen hohen klinischen Verdacht sowie enge Zusammenarbeit zwischen Dermatologen, pädiatrischen Onkologen und Pathologen. Generell müssen primär kutane Lymphome von sekundär kutanen Lymphomen, welche meist von nodalen oder extranodalen Lymphomen ausgehen, unterschieden werden. Die häufigsten primär kutanen Lymphome im Kindesalter sind T-Zell Lymphome, wobei Mycosis fungoides das häufigste kutane T-Zell-Lymphom darstellt, gefolgt von CD30+ lymphoproliferativen Erkrankungen. Während klinisch-pathologische Merkmale kutaner Lymphome bei Jugendlichen und Erwachsenen ähnlich sind, gibt es wichtige Unterschiede bezüglich klinischer Präsentation, Diagnose und Behandlung. Die hypopigmentierte Variante der Mycosis fungoides scheint in der pädiatrischen Altersgruppe überrepräsentiert zu sein. Prognose und Behandlung der Mycosis fungoides sind stadienabhängig. Die Mehrheit der Kinder weist ein frühes Krankheitsstadium auf und spricht gut auf topische Kortikosteroide und Phototherapie an.

Hypopigmented Mycosis Fungoides: Loss of Pigmentation Reflects Antitumor Immune Response in Young Patients. Cancers (Basel) 2020; 12:cancers12082007.

Abstract
Hypopigmented mycosis fungoides (HMF) is a form of cutaneous T-cell lymphoma (CTCL), a heterogeneous group of extranodal non-Hodgkin's lymphomas. HMF has a unique set of defining features that include light colored to achromic lesions, a predilection for darker skin phototypes, an early onset of disease, and predominance of CD8+ T-cells, among others. In the current review, we detail the known pathways of molecular pathogenesis for this lymphoma and posit that an active Th1/cytotoxic antitumor immune response in part explains why this variant is primarily seen in children/adolescents and young adults, who do not exhibit signs of immunosenescence. As a result of this potent cytotoxic response, HMF patients experience mostly favorable overall prognosis, while hypopigmentation may in fact represent a useful surrogate marker of cytotoxic immunity targeting the malignant cells. Understanding the molecular processes behind the specific features that define HMF may lead to improved diagnostic accuracy, personalized prognosis by risk stratification, and improved management of HMF. Moreover, improving our knowledge of HMF may aid our further understanding of other cutaneous lymphomas.

Abstract
Mycosis fungoides (MF) is the most common primary cutaneous lymphoma in pediatric patients. Given the indolent nature of MF, symptoms often present in childhood but may not be diagnosed as MF until adulthood. Delayed diagnosis is associated with poor long-term prognosis. Thus, increased clinician recognition and accurate diagnosis of early-stage MF in pediatric patients is critically important. In this review, we summarize the clinical features of the most common pediatric MF subtypes and highlight important differences between pediatric and adult MF. Moreover, we reviewed all pediatric MF case series published between 2008 and 2018 to analyze treatment modalities and identify emerging therapies. As treatment of pediatric MF is complex, selection of therapy varies significantly depending upon the specific clinical characteristics, disease severity, and patients' preferences.

Abstract
BACKGROUND Hypopigmented dermatoses, more evident in dark-skinned people, are a frequent cause of consultation. Their etiology includes a wide range of dermatoses, from benign to malignant diseases. The clinical presentation appears very similar between them, making the correct diagnoses and management a challenge. METHODOLOGY Clinical records and histopathological biopsies were identified and compared in patients of the "Dr. Manuel Gea González" General Hospital throughout a 16-year period with the presumptive diagnosis of hypopigmented epitheliotropic T-cell dyscrasia (HTCD) or hypopigmented mycosis fungoides (HMF). Immunostaining analysis was performed in each specimen, the panel of antibodies used was: CD3, CD4, CD7, CD8, CD20, and CD62L. RESULTS Thirty cases of 81 patients found in the registries were included in this study. The main age group was formed by children younger than 15 years old. The main clinical differences between both entities were gender, presence of plaques, and neck lesions. The most significant histopathological parameters used to differentiate both diagnoses were: severity of lymphocytic infiltration, the extent of epidermotropism, folliculotropism, presence of Pautrier's microabscesses, lymphocytes with cerebriform nuclei, and dermal fibroplasia. No immunohistochemical differences were found between them. CONCLUSION The clinical distinction between HTCD and HMF continues to be a challenge, therefore an extensive clinicopathological correlation must be performed. AbCD7 and AbCD62L were not useful to differentiate both dermatoses. This paper suggests that HTCD and HMF should be considered as the beginning and the end of the same clinical spectrum.

Int J Dermatol 2019; 59:127-133. [PMID: 31633200 DOI: 10.1111/ijd.14689] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 09/14/2019] [Accepted: 09/20/2019] [Indexed: 11/26/2022]
Abstract
BACKGROUND AND OBJECTIVE Less than 5% of cases of mycosis fungoides (MF) present with a cytotoxic/suppressor CD8+ phenotype. This study aimed to evaluate the clinical characteristics, treatment modalities, and clinical course in CD8+ MF patients. METHODS In a retrospective analysis of 353 MF patients in a referral center at Ankara University, Turkey, 29 patients that were diagnosed with CD8+ MF were included in the study. RESULTS CD8+ MF cases constituted 8.2% of all MF patients. The age at the time of diagnosis ranged between 6 and 81 years with a median value of 46 years. The female-to-male ratio was 1.41. Patients presented with erythematous scaly (69%), hyperpigmented (58.6%), poikilodermic (17.2%), and hypopigmented (17.2 %) patches/plaques. The most common sites of involvement were the trunk and lower extremities. The most common comorbidity was hypertension (24.1%, n: 7) with 13 patients (44.8%) having a history of at least one autoimmune disease. At the time of diagnosis, 93.2% of the patients had early-stage disease, and 6.8% of the patients had advanced stage. The mean follow-up period was 6.68 ± 6.04 years (range 1-28 years). Most of the patients were treated with skin-directed therapies. Complete remission was achieved in 17 (58.6%) patients, eight (27.6%) patients had partial remission, and four (13.8%) patients had stable disease. CONCLUSIONS We concluded that CD8+ MF is associated with an indolent course and in most patients, skin-directed therapies were found to be efficient to control the disease.

Abstract
BACKGROUND The aim of this study was to determine the relative frequency of primary cutaneous lymphoma (PCL) in Argentina according to the new World Health Organization (WHO)-European Organization for the Research and Treatment of Cancer (EORTC) classification system. METHODS A total of 416 patients from 21 dermatology services were included during a 5-year period (2010-2015); these patients were classified using WHO-EORTC criteria. RESULTS There were 231 (55.2%) males and 185 (44.8%) females; the male-to-female ratio was 1.35. The median age of the patients was 57 years (range, 0-90 years). Most patients were Caucasian (79%), and only 16% of patients were registered as Amerindian. Most patients (387/416, 93%) had cutaneous T-cell lymphoma (CTCL); 28 patients (6.7%) were diagnosed with cutaneous B-cell lymphoma (CBCL). The most frequent CTCL subtypes, in decreasing order of prevalence, were mycosis fungoides (MF), including its variants (75.7%); CD30+ primary cutaneous lymphoproliferative disorders (7.2%); and Sézary syndrome (SS) (3.1%). Cutaneous follicle center lymphoma was the most common CBCL subtype (2.9%). In the subset of patients ≤20 years of age, the most common condition was MF (57%), followed by extranodal NK-T nasal-type lymphoma (14%). CONCLUSIONS This study revealed relatively higher rates of MF and lower rates of CBCL in Argentinean patients that have been reported in American and European countries.

Abstract
Mycosis fungoides with large-cell transformation is historically associated with a poor prognosis. Pediatric cases of mycosis fungoides with large-cell transformation are rare, with only three other cases reported in the literature. We present the first case of a child with almost complete remission of his mycosis fungoides with large-cell transformation shortly after administration of psoralen plus ultraviolet A, interferon-alfa, and localized radiation.

Abstract
T-cell lymphoma, a collection of subtypes of Non-Hodgkin lymphoma, is a rare malignancy. The low prevalence of this disease has made it challenging to identify subtype-specific risk factors. Potential risk factors could enable us to identify high-risk patients and predict patient outcomes. Here, we report on the current epidemiologic and prognostic factors data associated with the individual subtypes both of peripheral T-cell lymphoma (PTCL) and cutaneous T-cell lymphoma (CTCL) found in large cohort and case studies. Additionally, with recent findings, as well as updates in the new World Health Organization (WHO) classification of lymphoid neoplasms, we consider what this could do to change our approach to this group of diseases.

Abstract
BACKGROUND Cutaneous T-cell lymphoma (CTCL) is an uncommon disease with various clinical presentations. The hypopigmented type is more common in individuals with a dark skin complexion. Moreover, childhood CTCL is more common in Mediterranean populations in comparison to the West. OBJECTIVE To describe CTCL in the Saudi population. DESIGN A retrospective collection of data on all cases of CTCL from 2010-2016. SETTING Dermatology clinic at a tertiary center in Riyadh, Saudi Arabia. PATIENTS AND METHODS We collected data on all cases of CTCL diagnosed clinically and confirmed pathologically. MAIN OUTCOME MEASURE(S) The number of cases of CTCL, gender, age at diagnosis and clinical subtypes. RESULTS The most common presentation among 125 patients was the classic type (patches and plaques) followed by the hypopigmented and poikilodermatous variants. Males were 58% of the population (n=72). The median age at diagnosis was 41 years and the range was 5 to 86 years. Thirteen percent were younger than 20 years of age. CONCLUSION Hypopigmented and poikilodermatous types of CTCL are more common in our population than in the West. LIMITATION Retrospective, single-center data may not be generalizable since difficult cases are more likely to be referred to a tertiary center.

Abstract
Mycosis fungoides (MF), the most common primary cutaneous T-cell lymphoma, is unusual in children. OBJECTIVES We aimed to describe the epidemiologic, clinical, histopathologic, and immunophenotypic characteristics of MF as well as treatments and course of disease in a pediatric case series. MATERIAL AND METHOD Data for all patients admitted to our pediatric hospital (Hospital Dr. J. P. Garrahan) in Argentina with a clinical and histopathologic diagnosis of MF between August 1988 and July 2014 were included. RESULTS A total of 14 patients were diagnosed with MF. The ratio of boys to girls was 1:1.33. The mean age at diagnosis was 11.23 years (range, 8-15 years). The mean time between onset and diagnosis was 3.5 years (range, 4 months-7 years). All patients had hypopigmented MF and 42% also presented the features of classic MF. Seven (50%) had the CD8+ immunophenotype exclusively. Seventy-eight percent were in stage IB at presentation. Phototherapy was the treatment of choice. Four patients relapsed at least once and skin lesions progressed in 3 patients. All patients improved. CONCLUSIONS MF is unusual in children. The hypopigmented form is the most common. Diagnosis is delayed because the condition is similar to other hypopigmented diseases seen more often in childhood. Although prognosis is good, the rate of recurrence is high, so long-term follow-up is necessary.

Abstract
Granulomatous mycosis fungoides (GMF) is a rare form of mycosis fungoides (MF) characterized by an infiltrate of atypical lymphocytes, histiocytes, and multinucleated giant cells. Clinically, GMF has a slowly progressing course with a worse prognosis than other forms of MF. With its peak incidence being in the fifth to sixth decade, GMF is rare in children and adolescents. Herein we describe a 14-year-old boy with GMF.

Abstract
Primary cutaneous lymphomas (PCL) are rare in pediatrics. Mycosis fungoides (MF) is the most frequent PCL diagnosed in childhood. There are various clinical variants of MF, including the hypopigmented MF (HMF). We present a 5-year-old boy with an 18-month history of progressive, generalized, nonpruritic hypopigmented lesions with central lacy erythema. He had no improvement with emollients. Skin biopsy showed typical features of HMF. He was treated with topical corticosteroids and tacrolimus and narrow-band ultraviolet B (NBUVB) phototherapy, with good response. HMF may mimic multiple skin disorders. Unusual hypopigmented skin lesions should be biopsied. Though phototherapy is effective, recurrence is common.

Abstract
Cutaneous T-cell lymohomas (CTCLs) are rare, but potentially devastating malignancies, with Mycosis fungoides and Sézary Syndrome being the most common. In our previous study, we identified and described regions of geographic clustering of CTCL cases in Texas by analyzing ∼1990 patients using two distinct cancer registries. In the current work, we describe in detail demographic patterns for this malignancy in our study population and apply logistic regression models to analyze the incidence of CTCL by sex, race, age, and clinical stage at the time of diagnosis. Furthermore, using Fisher's exact test, we analyze changes in incidence over time in the identified Houston communities with unusually high CTCL incidence. While CTCL primarily affects Caucasian individuals >55 years old, we confirm that it presents at a younger age and with more advanced disease stages in African-American and Hispanic individuals. Also, we demonstrate a significant increase in CTCL incidence over time in the identified communities. Spring, Katy, and Houston Memorial areas had high baseline rates. Furthermore, a statistically significant disease surge was observed in these areas after ∼2005. This report supplements our initial study documenting the existence of geographic clustering of CTCL cases in Texas and in greater detail describes demographic trends for our patient population. The observed surge in CTCL incidence in the three identified communities further argues that this malignancy may be triggered by one or more external etiologic agents.

Abstract
We provide a review of the pathological and clinical features for uncommon B-cell and T-cell lymphomas of childhood with a specific focus on advances in treatment approaches and outcomes. There is clearly a need for prospective investigation of both the clinical and biological features of the uncommon non-Hodgkin lymphoma subtypes in childhood. These results should lead to more uniform and more effective treatment approaches.

Abstract
Primary cutaneous lymphomas (CL) in children is rare. Only a few studies focused specifically on paediatric CL and therefore little is known whether primary CL in children are similar to or different from their adult counterparts with respect to the clinicopathological presentation, behaviour and prognosis. An extensive literature search using PubMed/MEDLINE from January 1995 through July 2014 was undertaken for articles reporting cases of paediatric CL. In addition, we identified 31 children with CL in our institutions. Mycosis fungoides and lymphomatoid papulosis are the two most prevalent lymphoma forms in children. A few entities of cutaneous lymphomas such as cutaneous diffuse large B-cell lymphoma leg type, and Sézary syndrome have not been reported so far in children. Other lymphoma entities such as hydroa vacciniforme-like lymphoma are mostly seen in certain geographic areas (Asia, Central and South America). In the paediatric population, low-malignant indolent forms such as primary cutaneous marginal zone lymphoma and primary cutaneous follicle centre lymphoma are very rare, whereas the more aggressive forms of B-cell lymphomas, precursor lymphoblastic lymphomas, and blastic plasmacytoid dendritic cell neoplasm are the most common forms in children, mostly involving the skin secondarily. Most paediatric lymphomas have similar clinicopathological features and course as their adults counterparts, particularly in the group of cutaneous T-cell lymphomas. The spectrum of cutaneous B-cell lymphomas in children significantly differs from the one in adults. Diagnostic work-up and treatment of paediatric patients with lymphomas are best achieved in close collaboration with paediatric haematopathologists and oncologists.

Abstract
Background. Mycosis fungoides (MF) is the most common subtype of cutaneous T-cell lymphoma. Extensive studies on Iranian MF patients are absent. The present study aimed to produce updated clinical information on Iranian MF patients. Methods. This was a retrospective, descriptive, single-center study, including all cases of MF seen in the Department of Dermatology, University Hospital of Isfahan, Iran, between 2003 and 2013. Data systematically recorded for each patient included clinical, biological, histological, and molecular findings. Results. Eighty-six patients with clinical and histologic diagnosis of MF were included in the study. Thirty-nine patients (45.3%) were male. Female predominance was observed in patients (male : female ratio is 1 : 1.2). Patients were between 7 and 84 years of age (median: 41). The interval from disease onset to diagnosis ranged from 0 to 55 years (median: 1 year). Eighteen cases (20.9%) had unusual variants of MF. The most common types included hypopigmented and poikilodermatous MF. Childhood cases of MF constituted 5.8% (5/86) of all patients. The early stages were seen in 82 cases (95.34%). Conclusion. The major differences in epidemiologic characteristics of MF in Iran are the lack of male predominance and the lower age of patients at the time of diagnosis.

Abstract
Few studies have evaluated Asian children with mycosis fungoides (MF). We report a series of patients from a tertiary dermatologic institution in Singapore. A retrospective review was performed of patients younger than 16 years old diagnosed with MF between 2000 and 2008 at the National Skin Centre, Singapore. Forty-six patients were identified. At initial presentation, a provisional diagnosis of MF was made in 19 patients (41.3%), pityriasis lichenoides chronica (PLC) in 11 (23.9%) and postinflammatory hypopigmentation due to eczema or other causes in 11 (23.9%). After skin biopsy, the hypopigmented variant of MF was diagnosed in 42 patients (91.3%). There was one case each of PLC-like MF, pigmented purpuric dermatosis-like MF, classic MF, and solitary MF. Pityriasis lichenoides coexisted in three cases (6.5%). All except one patient presented with the early patch-plaque stage of disease (stage IA/B). The disease did not progress in any of our patients after a mean follow-up of 71.0 ± 52.5 months. Twenty-seven patients (58.7%) had complete disease clearance after a mean duration of 27.1 ± 28.1 months; 15 (49.7%) of 32 patients who received narrowband ultraviolet B treatment had complete clearance within an average of 8.9 ± 5.3 months, but 7 patients relapsed within 14.9 ± 14.8 months. One patient with solitary MF failed multiple treatment modalities before eventually achieving disease clearance with photodynamic therapy. Hypopigmented MF is the most common MF variant in Asian children. The diagnostic difficulty is in differentiating this from PLC, which may coexist with MF. Long-term prognosis is generally favorable.

Abstract
Mycosis fungoides (MF), the most common cutaneous T-cell lymphoma (CTCL), is rare in childhood. The prognosis and response to treatment are poorly described in children. The objective of the current study was to evaluate the response to phototherapy in a pediatric cohort. A retrospective cohort study of all patients diagnosed with MF before the age of 18 years and referred to the regional CTCL phototherapy service was performed between January 1990 and April 2012. Twenty-eight patients were identified (13 boys, 15 girls). The mean age at presentation was 11.6 ± 3.9 years. The hypopigmented variant was noted in 79% of patients. All patients had stage I disease (IA = 10, IB = 17, unknown = 1). The median follow-up after diagnosis was 43 months (range 6-274 mos). Narrowband ultraviolet B (NbUVB; 311 nm) was used as first-line phototherapy in 18 patients and psoralen (bath) plus ultraviolet A (PUVA) was used in 8 patients. Complete or partial response was observed in 19 of 22 patients (86%). A further course of phototherapy was required in 7 of 12 patients (58%) treated with NbUVB after a median of 4 months (range 4-29 mos). A further course of phototherapy was required in four of eight patients (50%) successfully treated with PUVA after a median of 45.5 months (range 30-87 mos). No disease progression was noted over the follow-up (median 43 mos). The majority of patients in our cohort had hypopigmented MF. Phototherapy offers an effective option for treatment of childhood MF, although the period of remission may be greater in patients treated with PUVA.

Abstract
Cutaneous T-cell lymphoma describes a heterogeneous group of neoplasms of skin homing T cells that vary considerably in clinical presentation, histologic appearance, immunophenotype, and prognosis. This paper addresses the cutaneous T-cell lymphoma in Asians with respect to clinical-epidemiologic and histopathological features. Compared with Western countries, Asia usually has higher rates of cutaneous T-cell lymphomas such as extranodal NK/T-cell lymphoma, hydroa vacciniforme-like lymphoma, subcutaneous panniculitis T-cell lymphoma, and adult T-cell leukemia/lymphoma and lower rates of cutaneous B-cell lymphomas. Among many variants of mycosis fungoides, hypopigmented lesions, pityriasis lichenoides-like lesions, and ichthyosiform lesions are more prevalent in Asia than in the West. Adult T-cell leukemia/lymphoma is endemic in southwestern Japan especially in the Kyushu island. The clinicopathologic characteristics of cutaneous lymphoma vary according to geography, and this may be ascribed to genetic and environmental etiologic factors.
