Phototherapy is a useful noninvasive therapy, but it can induce cutaneous malignant tumours, including squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). We report on a 79-year-old man who had long-standing mycosis fungoides for 40 years, which had been treated with psoralen ultraviolet A therapy for 37 years at a dose of approximately 5000 J/cm(2) . Approximately 6 years before presentation, numerous types of cutaneous malignancies, including actinic keratosis, BCC and SCC, had begun to develop all over the patient's body. Read More

Purpose Of Review: Diagnosis and management of mycosis fungoides and Sézary syndrome (MF/SS) require accurate clinicopathological correlation and a multidisciplinary approach. We reviewed major advances in the field regarding diagnostic and prognostic tools as well as skin-directed therapies (SDTs) and systemic agents for MF/SS published in the past 2 years.

Recent Findings: Improved technology (T-cell receptor high-throughput sequencing) and increased multicenter collaboration (Cutaneous Lymphoma International Consortium) have led to diagnostic/prognostic advances. Read More

Psoriasis is a complex, chronic immune-mediated inflammatory disease that most commonly presents as well-demarcated erythematous plaques with micaceous scale, affecting roughly 3-4% of the US population [1-4]. Clinically, lesions are often well demarcated thick, scaly, erythematous plaques, characteristically located on the extensor surfaces, such as elbows and knees [1]. In most cases, clinical impression is sufficient to diagnose psoriasis. Read More

Mycosis fungoides is the most common form of cutaneous T-cell lymphoma. Stage IA and IB mycosis fungoides cutaneous T-cell lymphoma can be effectively controlled by skin-directed therapies such as the mechlorethamine gel approved by the Food and Drug Administration. Dermatology nurses play a key role in promoting good patient compliance through patient education about mycosis fungoides cutaneous T-cell lymphoma disease, proper administration of mechlorethamine gel, and connecting patients with patient assistance programs or other supportive services.

Folliculotropic mycosis fungoides (FMF) is a distinct variant of mycosis fungoides (MF) where atypical T-cells invade the hair follicles. The objective was to assess the clinical features, risk factors for progression, long-term outcome and response to treatment modalities in a large cohort of FMF patients. We, therefore, conducted a single-center retrospective study, reviewing 114 patients with FMF seen from 1987 to 2015 at the cutaneous T-cell lymphoma clinic of the MD Anderson Cancer Center.

In order to provide a common standard for the treatment of mycosis fungoides (MF) and Sézary syndrome (SS), the European Organisation for Research and Treatment of Cancer-Cutaneous Lymphoma Task Force (EORTC-CLTF) published in 2006 its consensus recommendations for the stage-adapted selection of management options for these neoplasms. Since then, the understanding of the pathophysiology and epidemiology of MF/SS has advanced, the staging system has been revised, new outcome data have been published and novel treatment options have been introduced. The purpose of the present document is to update the original recommendations bearing in mind that there are still only a limited number of controlled studies to support treatment decisions for MF/SS and that often treatment is determined by institutional experience and availability.

Depending on the other cytokines (IL-4, GM-CSF) present during in vitro culture of healthy volunteers' monocytes, IL-32 increased the maturation of CD11c(+) myeloid dendritic cells (mDC) and/or CD163(+) macrophages, but IL-32 alone showed a clear ability to promote dendritic cell (DC) differentiation from monocytes.

Primary cutaneous anaplastic large cell lymphoma (PC-ALCL) is a CD30+ lymphoproliferative disorder (LPD) of the skin with a relatively good prognosis in the absence of high-stage disease. CD30+ LPDs comprise approximately 25%-30% of primary cutaneous lymphomas and as a group represent the second most common clonal T-cell neoplasm of the skin behind mycosis fungoides. Diagnosis of PC-ALCL relies strongly on clinicopathologic correlation given the potential morphologic, clinical and molecular overlap with the other cutaneous CD30+ LPD, lymphomatoid papulosis, and more aggressive hematolymphoid neoplasms.
