Classifications of cutaneous lymphomas and lymphoproliferative disorders: An update from the EORTC cutaneous lymphoma histopathology group. J Eur Acad Dermatol Venereol 2024; 38:1491-1503.

Abstract
The classification of primary cutaneous lymphomas and lymphoproliferative disorders (LPD) is continuously evolving by integrating novel clinical, pathological and molecular data. Recently two new classifications for haematological malignancies including entities of cutaneous lymphomas were proposed: the 5th edition of the WHO classification of haematolymphoid tumours and the International Consensus Classification (ICC) of mature lymphoid neoplasms. This article provides an overview of the changes introduced in these two classifications compared to the previous WHO classification. The main changes shared by both classifications include the downgrading of CD8+ acral T-cell lymphoma to CD8+ acral T-cell LPD, and the recognition of entities that were previously categorized as provisional and have now been designated as definite types including primary cutaneous small or medium CD4+ T-cell LPD, primary cutaneous gamma/delta T-cell lymphoma, primary cutaneous CD8+ aggressive epidermotropic cytotoxic T-cell lymphoma, Epstein-Barr virus-positive mucocutaneous ulcer. Both classifications consider primary cutaneous marginal zone B-cell clonal neoplasm as an indolent disease but use a different terminology: primary cutaneous marginal zone lymphoma (WHO) and primary cutaneous marginal zone LPD (ICC). The 5th WHO classification further introduces and provides essential and desirable diagnostic criteria for each disease type and includes chapters on reactive B- or T-cell rich lymphoid proliferations formerly referred as cutaneous pseudolymphomas, as well as histiocyte and CD8 T-cell rich LPD in patients with inborn error of immunity. As already emphasized in previous lymphoma classifications, the importance of integrating clinical, histological, phenotypic and molecular features remains the crucial conceptual base for defining cutaneous (and extracutaneous) lymphomas.

[PMID: 37317772 DOI: 10.25259/ijdvl_1003_2021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Accepted: 01/01/2023] [Indexed: 06/16/2023]
Abstract
Background Follicular mycosis fungoides is a distinct variant of mycosis fungoides with a broad clinical spectrum. Recently, many studies have indicated that follicular mycosis fungoides should be divided into different subtypes with disparate prognoses. Objective To define the clinicohistopathologic features and outcomes of follicular mycosis fungoides and to identify risk factors that may be related to the prognosis of Chinese patients with follicular mycosis fungoides. Materials and methods We conducted a single-centre retrospective study and reviewed the clinical, histopathologic and immunophenotypic data of 12 patients diagnosed with follicular mycosis fungoides between 2009 and 2020 in the Department of Dermatology of West China Hospital of Sichuan university. Results A total of 12 patients (seven males and five females) with a mean age of 30 ± 14 years (age range 16-55 years) were included. Scalp and face were the most common involved sites (100%). Follicular papules, acneiform lesions, plaques, and nodules, were the main clinical presentations. Histopathological findings were consistent with the classic manifestations of follicular mycosis fungoides, including folliculotropism, perifollicular and intrafollicular lymphocytic infiltrates and mucinous degeneration. Interferon α-1b was the most common treatment. Four patients died of follicular mycosis fungoides in three years. Notably, immunohistochemical analysis revealed a decreased number of CD20+ cells in the deceased patients. Limitations This is a retrospective evaluation with a small number of cases; further prospective studies are warranted to support our inferences. Conclusion Our patients were much younger than in previous studies. The observed difference in this cohort may be explained by race, in addition to the limited number of cases. A decreased number of B cells might be associated with a poor prognosis, and more studies are necessary to discover the role of B cells in follicular mycosis fungoides as well as in mycosis fungoides.

Abstract
This study pioneers the application of artificial intelligence (AI) and hyperspectral imaging (HSI) in the diagnosis of skin cancer lesions, particularly focusing on Mycosis fungoides (MF) and its differentiation from psoriasis (PsO) and atopic dermatitis (AD). By utilizing a comprehensive dataset of 1659 skin images, including cases of MF, PsO, AD, and normal skin, a novel multi-frame AI algorithm was used for computer-aided diagnosis. The automatic segmentation and classification of skin lesions were further explored using advanced techniques, such as U-Net Attention models and XGBoost algorithms, transforming images from the color space to the spectral domain. The potential of AI and HSI in dermatological diagnostics was underscored, offering a noninvasive, efficient, and accurate alternative to traditional methods. The findings are particularly crucial for early-stage invasive lesion detection in MF, showcasing the model's robust performance in segmenting and classifying lesions and its superior predictive accuracy validated through k-fold cross-validation. The model attained its optimal performance with a k-fold cross-validation value of 7, achieving a sensitivity of 90.72%, a specificity of 96.76%, an F1-score of 90.08%, and an ROC-AUC of 0.9351. This study marks a substantial advancement in dermatological diagnostics, thereby contributing significantly to the early and precise identification of skin malignancies and inflammatory conditions.

Abstract
INTRODUCTION Dermatoscopy is a frequently used non-invasive diagnostic procedure. OBJECTIVES Considering that mycosis fungoides (MF) mimics parapsoriasis clinically in early stages, we aim to determine the dermatoscopic criteria and the histopathological correlations in patients with MF and small plaque parapsoriasis (SPP). METHODS This prospective study involved 28 patients with clinical and histopathological diagnoses of MF and 31 patients with SPP. Videodermoscopy and USB capillaroscope were used to evaluate the patients vessels at ×200 magnification. Vascularity was evaluated through microvascular density (MVD) scoring involving CD34 antibody staining. RESULTS Fifty-nine patients were included in this study. The scores corresponding to the presence of short linear vessels, linear-curved vessels, branching linear vessels, and non- structured orange-colored areas were significantly higher in the MF patients than in the SPP patients (P < 0.05). The highest MVD (P = 0.01) scores were also higher in the MF patients than in the SPP patients. CONCLUSIONS The SPP and early-stage MF patients differed in their MVD scores, and the findings correlated with the dermatoscopy and lesional capillaroscopy findings. Differentiating features between SPP and MF were thus identified.

Abstract
Cutaneous T-cell lymphomas are an heterogeneous group of uncommon lymphoid neoplasms that are challenging to diagnose and require close collaboration between dermatologists, pathologists and hematologists/oncologists. This article reviews the most common cutaneous T-cell lymphomas: mycosis fungoides (both classic and variant forms) as well as its leukemic counterpart Sézary syndrome, CD30+ T-cell lymphoproliferative disorders including the ever-expanding group of lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma, and primary cutaneous CD4+ small/medium lymphoproliferative disorder. We discuss the classic clinical and histopathologic features of these lymphomas and review how they can be distinguished from reactive entities. In particularly, updates to these diagnostic categories and current controversies in classification are highlighted. Moreover, we review the prognosis and treatment for each entity. These lymphomas exhibit variable prognosis, and therefore it is important to correctly classify atypical cutaneous T-cell infiltrates for appropriate patient treatment and prognosis. Cutaneous T-cell lymphomas are at the interface of several medical specialties; this review seeks to summarize key features of these lymphomas and highlight new and emerging insights into these lymphomas.

Abstract
Background Cutaneous T-cell lymphoma (CTCL) is a chronic and progressive disease that has a major impact on quality of life (QoL). Objectives To describe the impact of the different stages of disease in patients with classical mycosis fungoides, folliculotropic mycosis fungoides, and Sézary syndrome on generic- and dermatology-specific QoL and the relation with itch. Methods A cross-sectional cohort study of patients with classical mycosis fungoides, folliculotropic mycosis fungoides, and Sézary syndrome was performed. Outcomes were the Skindex-29 score, Impact of Chronic Skin Disease on Daily Life which includes a visual analogue scale itch, and RAND-12. Results One hundred six patients with CTCL were included. Compared to the total mycosis fungoides group, patients with Sézary syndrome had significantly worse Skindex-29 scores. Patients with advanced disease had statistically higher scores for the symptom (P = .007), functioning (P = .002), and total score (P = .012). The degree of itching was strongly correlated with the total Skindex-29 score (R = 0.713, P < .001). Conclusion The different stages of CTCL can have a significant effect on multiple domains of generic- and dermatology-specific QoL. Itch was strongly correlated with QoL and therefore can be used as an overall QoL indicator. The effect on QoL, even in patients with early-stage disease, should not be underestimated.

Abstract
BACKGROUND Ten-year survival rates in mycosis fungoides (MF) broadly varies, however, there is no standardized prognostic index available. This is presumably due to low prevalence, heterogeneity, and diagnostic challenges in MF. Recent studies have focused on identifying objective prognostic indices by using different parameters for survival determinants. The Cutaneous Lymphoma International Prognostic Index (CLIPI) and the Prospective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) represent prototypical studies that identify prognostic factors, seeking to improve management and outcomes in early-stage MF. Detecting these factors and stratifying MF patients according to their disease progression risk may help to manage these patients more efficiently. AIMS Review the current literature to determine the risk factors determining prognosis in MF. METHODOLOGY A Comprehensive literature search was performed using electronic online databases "PubMed" and "Google Scholar" using key words 'prognostic factor', 'prognostic indicator', 'mycosis fungoides', 'Sezary syndrome', 'Skin Lymphoma', 'Cutaneous Lymphoma'. Articles published in English language were considered for the review. RESULTS The strongest prognostic factor in MF patients is the stage of the disease. T stage and the presence of extracutaneous disease are the most important factors for survival. Other factors that are associated with worse prognosis are male gender, age >60, presence of plaques, folliculotropism, eosinophilia and lymph node stage above N1/Nx. Elevated LDH was associated with later tumor stages and large cell phenotype at diagnosis had a better prognosis. KIR3DL2 was associated with malignant transformation. CONCLUSION The PROCLIPI study has assessed risk factors collected in MF patients from different countries and across different ethnicities following a rigorous clinicopathologic process. The findings presented here illustrated that disease prognosis in early stages depends on many contributing factors. Detection and stratification of such factors may allow a personalized approach to management of these patients.

Abstract
The cutaneous lymphomas are malignancies of T-cell and B-cell lymphocytes in which the skin is the primary organ of involvement. The cutaneous T-cell lymphomas include variants that can mimic the presentation of common skin diseases or arthropod bites. Mycosis fungoides, the most common cutaneous T-cell lymphoma, usually presents as fixed asymptomatic patches or plaques in sun-protected areas. The cutaneous B-cell lymphomas have fewer variants that often present as papules or nodules that can mimic nonmelanoma skin cancers. Some therapies for cutaneous lymphoma have unique side effects such as central hypothyroidism, hyperlipidemia, and peripheral neuropathy.

Abstract
BACKGROUNDS Follicular mycosis fungoides (FMFs) is a distinct form of T-cell lymphoma whose course is considered aggressive. METHODS A retrospective study with long-term follow-up of 20 patients diagnosed with spiky/keratosis-pilaris-like FMF between 2008 and 2017 was conducted. RESULTS Twelve males and eight females were identified, with a mean age at first diagnosis of 59 years (range 42-86). Hyperkeratotic follicular papules were the sole clinical finding in 16 of 20 patients. A diagnostic delay between first symptom development and initial diagnosis was frequent (mean 42 months). The head/neck region was concurrently affected only in two patients. Disease stage at diagnosis was IA in two patients (10%) and IB in 18 (90%). Five patients had almost complete lesion regression, whilst there was only a slight improvement, without regression in 14. Two patients developed infiltrated papules, comedones, and small cysts during follow-up. Only one patient progressed to tumor stage (IIB) five years after the first diagnosis. The mean follow-up was seven years (range: 12-180 months). None of them died of cutaneous lymphoma. CONCLUSIONS FMF presenting with only spiky/keratosis-pilaris-like lesions have an excellent prognosis at medium-term follow-up. Early recognition of patients with this peculiar FMF presentation might lead to identifying prognostic factors.

Abstract
BACKGROUND Primary cutaneous gamma-delta T-cell lymphoma (PCγδTCL) and primary cutaneous aggressive epidermotropic T-cell lymphomas (PCAETCL) are rare aggressive cytotoxic cutaneous lymphomas (CyCL) often difficult to diagnose. Histopathologically, PCAETCL and PCγδTCL may resemble mycosis fungoides (MF) and the presence of adnexotropism in CyCL (CyCL) contributes to this diagnostic challenge, especially in the setting of atypical and double-negative phenotypes. METHODS In this retrospective study clinical data and histopathological section of 91 patients were analyzed for signs of clinical and histopathological signs adnexotropism. RESULTS Adnexotropism was identified in 48.4% (44/91) of cases, including PCAETCL (40.9%, 18/44), PCγδTCL and cytotoxic cutaneous lymphomas, not otherwise specified (CyCTCL, NOS) (43.2%, 19/44 and 15.9%, 7/44). Comparison between disease-related mortality with Kaplan-Meier survival analysis of non-adnexotropic vs adnexotropic CyCL did not show any significant difference between the two groups (P = 0.8). Clinically they present with patches, plaques, and tumors and commonly with ulceration, but follicular prominence or alopecia are rare. Clinical signs of adnexotropism such as alopecia and hypo- or anhidrosis were rarely seen. CONCLUSION Adnexotropism is a common finding in CyCL, especially in PCAETCL. Adnexotropic CyCL may be histopathologically difficult to distinguish from folliculotropic mycosis fungoides. A comprehensive IHC panel should be routinely performed in such cases.

Abstract
Lichen spinulosus (LS) is an uncommon skin condition mostly in children and adolescents but uncommon in adults. It presents as a group of hypopigmented or skin-colored follicular papules and keratotic spines with a sandpaper-like appearance. There is a lymphohistiocytic infiltrate in the dermis centered around hair follicles. We present a rare case of LS in a 52-year-old woman with a rough, bumpy, itchy rash affecting the trunk and extremities. Her rash consisted of clusters of hyperkeratotic follicular-based spiny papules. Histologic sections demonstrated several dilated hair follicles filled with keratotic plugs surrounded by a dense perifollicular lymphohistiocytic infiltrate, particularly at the level of the infundibula, that extended into the follicular epithelium.

Abstract
Folliculotropic mycosis fungoides (FMF) is characterized by a broad clinical spectrum and worse prognosis compared to classical MF. This study aimed to evaluate the clinical characteristics, treatment modalities and long-term outcome and risk factors for progression and survival of FMF patients. We conducted a single-center retrospective study and reviewed 53 patients diagnosed with FMF between 1990 to 2019 in a referral center at Ankara University, Turkey. Regarding to stage at diagnosis, 24 patients (45.3%) had advanced-stage disease (≥IIB). Follicular papules was observed in 66% and alopecia in 49.1% of the cases. Forty-three patients (81.1%) suffered from pruritus. The majority of the patients (92.4%) had at least one systemic therapy. Complete remission was achieved in 24.5% of the patients. The median time of overall survival (OS) was 50 months (range 9-324 months) and 5-year and 10-year OS was 83% and 69%, respectively. Twenty-eight (52.3%) patients progressed to more advanced stages and seven (13.2%) patients died due to MF during the follow-up period. FMF is associated with a progressive course and in most patients, skin-directed therapies were found to be inefficient to control the disease and multiple systemic therapeutic agents were required to control the disease.

Abstract
BACKGROUND Folliculotropic mycosis fungoides (FMF) is a distinct variant of mycosis fungoides. Recent studies recognized indolent and aggressive subgroups of FMF, but there is controversy how patients presenting with plaques should be classified. The present study describes the histopathologic features of 40 FMF plaques. The aim of the study was to identify risk factors for disease progression and poor outcome in this group. METHODS Clinical, histopathological, and immunophenotypical data from 40 patients with plaque stage FMF were reviewed and analysed for risk factors for disease progression and survival. RESULTS After a median follow-up of 80 months, disease progression occurred in 20 of 40 patients. Percentage of atypical cells, cell size, percentage of Ki-67+ cells, and co-existent interfollicular epidermotropism, but not the extent of perifollicular infiltrates, were associated with disease progression and reduced survival, while extensive follicular mucinosis was associated with increased survival. CONCLUSIONS This study underlines that FMF patients presenting with plaques represent a heterogeneous group and that a subgroup of these patients may have an indolent clinical course. It further shows that histological examination is a valuable tool to differentiate between indolent and aggressive disease.
