[Translational medicine in dermatology: experience in the Specialties Hospital of the 21st Century National Medical Center].

Through multidisciplinary research, translational medicine allows a comprehensive approach to diseases in order to provide patients with adequate treatment, whose aim is personalized and precision medicine. In this context, the Cellular Immunology Laboratory of the Immunochemistry Research Unit, and the Dermatology Service of the 21st Century National Medical Center's Specialties Hospital (Hospital de Especialidades del Centro Médico Nacional Siglo XXI) have achieved a partnership that aspires to provide better quality patient care. This objective is achieved by evaluating the inflammatory skin infiltrates in different pathologies to observe changes in local immunity related to the response to treatment, and with the disease progression distinguish between dermatological diseases, highlight the importance of comprehensive skin care, and make decisions about treatment choice.

Chlormethine Gel for Treatment of Patients with Mycosis Fungoides: Best Practices and Guidance to Clinicians.

Background: Mycosis fungoides (MF) is the most common form of cutaneous T cell lymphoma. While multiple guidelines provide treatment recommendations, there are currently no clear treatment algorithms for MF. Chlormethine gel is recommended by major treatment guidelines as a first-line option for stage IA-IIA disease, and, on the basis of these guidelines, used in combination with other therapies in patients with advanced-stage MF in clinical practice.

Predicting Prognosis of Early-Stage Mycosis Fungoides with Utilization of Machine Learning.

Mycosis fungoides (MF) is the most prevalent type of cutaneous T cell lymphomas. Studies on the prognosis of MF are limited, and no research exists on the potential of artificial intelligence to predict MF prognosis. This study aimed to compare the predictive capabilities of various machine learning (ML) algorithms in predicting progression, treatment response, and relapse and to assess their predictive power against that of the Cox proportional hazards (CPH) model in patients with early-stage MF.

It is approved for the treatment of mycosis fungoides, Hodgkin's lymphoma, and systemic anaplastic large cell lymphoma. Brentuximab has been associated with a number of potential adverse reactions; however, reports of renal complications are rare.

Dermoscopy of mycosis fungoides: could it be a confirmatory aid to the clinical diagnosis?

Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma that is difficult to be differentiated from other dermatological diseases. Dermoscopy is an easy and non-invasive office procedure that is widely used nowadays in the diagnosis of a wide variety of skin diseases. This prospective study aimed to describe and to differentiate the dermoscopic pattern of different stages and to compare the dermoscopic features observed in different clinical types of mycosis fungoides.

Clinically assessed mycosis fungoides tumor burden index as a prognostic marker in tumor-stage mycosis fungoides: a retrospective cohort study.

Prognostic markers are needed for tumor-stage mycosis fungoides (MF) because of their variable prognosis. The objectives of this study were to explore prognostic markers for tumor-stage MF and assess the prognostic significance of clinically assessed MF tumor burden index (MTBI). MTBI was devised to consider the tumor size ≥ 2 cm, number ≥ 5, ulcers, and body surface area ≥ 50%.

A Case Report of Folliculotropic Mycosis Fungoides: Diagnostic Criteria and Treatment Strategy.

Folliculotropic mycosis fungoides (F-MF) is considered a unique variant of mycosis fungoides (MF), which is a form of cutaneous T-cell lymphomas (CTCLs). F-MF can appear in various forms, including patches, papules, plaques, nodules, and tumors. It often affects the face and extremities, with some cases involving the eyebrows.

Cutaneous T cell lymphoma atlas reveals malignant T2 cells supported by a B cell-rich tumor microenvironment.

Cutaneous T cell lymphoma (CTCL) is a potentially fatal clonal malignancy of T cells primarily affecting the skin. The most common form of CTCL, mycosis fungoides, can be difficult to diagnose, resulting in treatment delay. We performed single-cell and spatial transcriptomics analysis of skin from patients with mycosis fungoides-type CTCL and an integrated comparative analysis with human skin cell atlas datasets from healthy and inflamed skin.

Skin barrier dysfunction in cutaneous T-cell lymphoma: From pathogenic mechanism of barrier damage to treatment.

Cutaneous T-cell lymphoma (CTCL) is a group of non-Hodgkin lymphomas characterized by multiple erythematous patches, plaques, or even nodules on the skin. As the disease progresses, patients develop widespread pruritic skin lesions, leading to skin barrier dysfunction, which significantly impacts their quality of life, appearance, and social adaptation. The pathogenesis of CTCL is not fully understood.

A Retrospective Comparison Between Home and in-Office NB-UVB Efficacy for Patients With Mycosis Fungoides.

Introduction: This study addresses the gap in research comparing the effectiveness between home and in-office narrowband ultraviolet B (NB-UVB) phototherapy for the treatment of mycosis fungoides (MF). Elderly and disabled patients with this condition disproportionally lack access to home units due to insurance denial.

Materials And Methods: A retrospective review included patients diagnosed with MF or Sezary syndrome who underwent either in-office or home UVB between 2016 and 2023.

Haematogenous seeding in mycosis fungoides and Sézary syndrome: Current evidence and clinical implications.

Cutaneous T-cell lymphomas (CTCLs) are a heterogeneous group of diseases characterised by abnormal neoplastic T-cell growth in the skin. Mycosis fungoides (MF), the most common CTCL, manifests as erythematous skin patches and/or plaques, tumours or erythroderma. The disease may involve blood, lymph nodes and rarely viscera.

[Hypopigmented mycosis fungoide. Case report].

Background: Hypopigmented mycosis fungoide (HMF) is a rare variant of cutaneous T-cell lymphoma of unknown pathogenesis. It is the most common cutaneous lymphoma in childhood. It is characterized by hypopigmented macules in non-photoexposed areas, generally asymptomatic.

Nanopore Sequencing for T-Cell Receptor Rearrangement Analysis in Cutaneous T-Cell Lymphoma.

Analysis of T-cell receptor (TCR) clonality is a major diagnostic tool for lymphomas, particularly for cutaneous T-cell lymphomas (CTCL) like Mycosis fungoides and Sézary syndrome. However, a fast and cost-effective workflow is needed to enable widespread use of this method. : We established a procedure for TCR rearrangement analysis via Oxford Nanopore Technology (ONT) sequencing.

Histopathologic Comparisons of Discoid Lupus Erythematosus and Folliculotropic Mycosis Fungoides in a Series of 43 Cases.

Background: Folliculotropic mycosis fungoides (FMF) is a rare cutaneous malignancy that can be mistaken for inflammatory diseases, such as discoid lupus erythematosus (DLE), due to the variability of histopathological findings.

Methods: This study aims to provide dermatopathologists with evidence-based histopathologic criteria to distinguish DLE from FMF by reporting overlapping and distinguishing microscopic features. Forty-three biopsies from patients with a confirmed diagnosis of DLE or FMF were graded for the presence or absence of 18 histopathologic features.
