Effectiveness and tolerability of chlormethine gel for the management of mycosis fungoides: a multicenter real-life evaluation
BackgroundTopical chlormethine (CL) is recommended as a first-line treatment for early-stage mycosis fungoides (MF) and in 2017, the European Medicines Agency approved the CL gel formulation to treat adult patients. More recently, to increase patient compliance and adherence, clinicians have developed flexible protocols that allow the concomitant use of CL gel with topical corticosteroids in daily practice regimens. Therefore, sharing real-life data on CL gel use and side effects management may help improve the use of this agent.ObjectivesTo expand knowledge about the actual use of CL gel in patients with MF, the present study assessed the improvement of MF skin lesions after CL gel treatment and provided information on the management of cutaneous adverse events (AEs) in a real-life setting.MethodsThis was an Italian retrospective study conducted among six dermatology referral centers. Patients ≥18 years affected by MF and in treatment with CL gel (160 µ/g), alone or in combination according to routine clinical practice, between December 2019 and December 2021 were considered. The study’s primary aim was to evaluate the effectiveness of CL gel in terms of overall response rate (ORR) after 3 months of treatment.ResultsA total of 79 patients (61% male) with different stages of MF (84% early stage) were included. CL gel was prescribed mainly in association with topical corticosteroids (66% of patients). ORR after 3 months of treatment was 42%, with no differences between early- and advanced-stage MF. Response rates improved over time up to 97% after 18 months of treatment. Overall, 66 AEs were reported in 67% of patients; most were hyperpigmentation (45%) and irritant contact dermatitis (37%). Six AEs led to treatment discontinuation, and five out of six (83%) patients who reported these events resumed treatment after interruption. No AEs were classified as severe.ConclusionsOur observations support the use of CL gel in patients with early- and advanced-stage MF, making it a valuable treatment option
Vitiligo: Unmet Need, Management and Treatment Guidelines
Vitiligo is a chronic depigmenting disorder characterized by characteristic, non-scaly, chalky-white skin macules and patches, due to the loss of skin pigment. Its exact pathogenesis is still not fully un-derstood but it seems to be an autoimmune disease where the combination of genetic, environmental, and immune factors contributes to the destruction of melanocytes in the epidermis. Vitiligo is classified into different types based on its clinical characteristics and distribution patterns. The two main forms of vitiligo are non-segmental vitiligo (NSV) and segmental vitiligo (SV). NSV is the predominant form, characterized by symmetrical skin patches, that tend to evolve over time. In contrast, SV has unilateral or band-shaped lesions that progress rapidly but often stabilize early. Herein, current unmet needs in terms of psychosocial consequences and relative lack of valid therapeutic approaches are critically analyzed and put in perspective in the Italian prescribing scenario. Finally, available management guidelines are illustrated and briefly compared, to provide context for upcoming treatment options
Primary Cutaneous Gamma-Delta T Cell Lymphomas: A Case Series and Overview of the Literature
Primary cutaneous gamma-delta T cell lymphomas (PCGDTCLs) are rare and aggressive cutaneous malignancies that have been diagnostically challenging for dermopathologists and clinicians since their first published descriptions in 1991. Since then, the availability of immunostaining for T cell receptors γ and δ in formalin-fixed paraffin-embedded samples has greatly increased our knowledge of the gamma-delta phenotype by showing that it may also be present in the context of indolent entities, such as mycosis fungoides (MFs) and lymphomatoid papulosis, and this has raised questions concerning its diagnostic and prognostic implications. We here describe the histological and clinical differences between the dermo-epidermal and subcutaneous sub-groups of PCGDTCL observed in a cohort of 20 patients attending a single experienced centre, with particular focus on cases with an MF-like presentation, which are still less well defined than those of classic MF

CUTANEOUS B-CELL LYMPHOMAS: UPDATE ON DIAGNOSIS, RISK-STRATIFICATION, AND MANAGEMENT
: PCBCLs are a group of Non-Hodgkin's B-cell lymphomas originating in and usually confined to the skin, representing approximately one fourth of primary cutaneous lymphomas (PCL). Their current classification system has been the result of the joint World Health Organization (WHO) - European Organization for Research and Treatment of Cancer (EORTC) consensus in 2018. To date, several types of PCBCLs have been described in the scientific literature, with different clinical presentation and prognosis. Primary cutaneous follicle-center lymphoma (PCFCL) and primary cutaneous marginal zone lymphoma (PCMZL) are the most common forms, with a typical indolent course. On the contrary, primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT) is less common, yet more aggressive, with a reported 5-year overall survival of approximatively 50%. In this review, we outline the PCBCLs defining diagnostic criteria, report the features of the less common subtypes and summarize the noteworthy therapeutical options currently available in this field
The Microenvironment’s Role in Mycosis Fungoides and Sézary Syndrome: From Progression to Therapeutic Implications
Background: Mycosis fungoides (MF) and Sezary Syndrome (SS) are the most common cutaneous T-cell lymphomas. It has been hypothesized that the interaction between the immune system, cutaneous cells, and neoplastic elements may play a role in MF/SS pathogenesis and progression. Methods: This paper aims to revise in a narrative way our current knowledge of the microenvironment’s role in MF/SS. Results and Conclusions: Literature data support a possible implication of microenvironment cells in MF/SS pathogenesis and progression, opening up new therapeutic avenues
An expert consensus report on mycosis fungoides in Italy: epidemiological impact and diagnostic-therapeutic pathway
Mycosis fungoides (MF) is a rare neoplasm representing the most frequent form of primary cutaneous T-cell lymphoma (CTCL). Diagnosis of MF is generally complex, often requiring integration of clinical, histological, immunophenotypic and molecular data. Currently, there are no epidemiological data supported by registries or local studies on MF in Italy. Moreover, the clinical management of MF in Italy is heterogeneous, and differs according to the geographical area and experience of the physician who manages the disease. Considering the uncertainties in the current scenario for MF in Italy, a consensus project involving experts on CTCL was initiated to define the epidemiological impact of MF and obtain information about the current diagnostic and therapeutic pathway of this disease in Italy. The prevalence of MF in Italy was estimated to be 6,800 patients, 4,900 of whom with early stage of disease; the estimated incidence ranged between 270 and 330 new cases per year. Among the clinical figures involved in the multidisciplinary management of MF, dermatologists were recognized as a reference point for both diagnosis and therapeutic decisions. These findings suggest the importance of monitoring both the disease and its management; it is, therefore, interesting to set up regional registries for monitoring and recognition of rare tumor status for MF. The results further indicate the need to train physicians to favor more rapid diagnosis and simplify the pathway for referring patients to reference centers with adequate diagnostic and treatment standards. In light of the forthcoming introduction of new therapies, the development of a nationwide PDTA (Path of Diagnostic Therapeutic Care, in Italian defined as Percorso Diagnostico-Terapeutico Assistenziale) is also of substantial importance
