We describe a patient with a 30-year history of mycosis fungoides (MF) and renal transplantation performed 3 years before he presented with an ulcerated tumour in the lumbosacral area. Biopsy revealed a lymphatic infiltrate of medium-sized, pleomorphic T cells expressing the gamma-delta T-cell receptor. Radiological staging and bone marrow biopsy revealed no extracutaneous involvement. Despite reduction in systemic immunosuppressants, total skin electron beam radiotherapy and systemic chemotherapy, the disease followed a highly aggressive course and the patient died 31 years after initial diagnosis of MF...

The classification of cutaneous lymphomas is multidisciplinary and requires the correlation between clinical, histopathological, immunohistochemical, and molecular diagnostic elements. In this article, we present four different cases of CD30-positive T-cell lymphoma with cutaneous manifestations. We compare cases with definitive diagnosis of papulosis lymphomatoid type C, primary cutaneous anaplastic large T-cell lymphoma, systemic anaplastic large T-cell lymphoma with secondary skin involvement, and mycosis fungoides with large cell transformation, highlighting the importance of clinicopathological correlation to classify these cases...

Secondary cutaneous amyloidosis refers to clinically unapparent amyloid deposits within the skin in association with a pre-existing skin condition or skin tumors, such as basal cell carcinoma, porokeratosis, solar elastosis, Bowen's disease, and mycosis fungoides. A 70-year-old woman presented with a 6-month history of asymptomatic multiple yellowish plaques on both legs. She had been diagnosed with mycosis fungoides 7 years ago and was treated with psoralen and ultraviolet A radiation (PUVA) therapy, narrow-band ultraviolet B (UVB) therapy, and acitretin for 5 years...

The aim of this 10-year monocentric prospective study was to determine a cut-off value of Fas/CD95 expression by peripheral blood CD4+ T lymphocytes in discriminating patients with mycosis fungoides from controls with cutaneous benign lymphocytic conditions. CD95 expression in peripheral blood CD4+ T lymphocytes was measured using flow cytometry in 330 patients referred for diagnosis: 104 with mycosis fungoides and 226 with eczema, psoriasis, drug reaction, etc. The sensitivity and specificity of different thresholds of CD95 expression were calculated regarding the final diagnosis of patients with mycosis fungoides or controls...

Importance: In a phase 1 trial, single-dose O6-benzylguanine with topical carmustine for patients with early stage (stage IA through stage IIA) cutaneous T-cell lymphoma, mycosis fungoides (MF) type, resulted in clinical responses proportional to inhibition of O6-alkylguanine DNA alkyltransferase activity, but a maximum tolerated dose (MTD) was not reached. Objective: To determine whether dose escalation of carmustine in combination with dual-dose O6-benzylguanine to prolong alkyltransferase inhibition could reach an MTD...

BACKGROUND: Photochemotherapy with psoralen and ultraviolet A (PUVA), with or without adjuvant interferon-α (IFN-α), is a first line therapy for early stage mycosis fungoides and other forms of cutaneous T-cell lymphoma (CTCL). However, the mechanism by which PUVA with IFN-α work in CTCL is poorly understood. PURPOSE: To develop a model to investigate the mechanisms of PUVA and PUVA with IFN-α in CTCL cells. METHODS: An in vitro model to study the molecular mechanisms of PUVA was created using two different CTCL cell lines, MyLa, which has functional p53, and HuT-78, in which p53 is inactivated due to a homozygous nonsense mutation...

BACKGROUND: Erythroderma is a serious medical condition characterized by inflamed red skin involving over 90% of the body. It can be the common presentation of different diseases, therefore clinical diagnosis can be problematic. Controversial data are reported regarding the diagnostic value of histological examination in erythroderma subjects. METHODS: A retrospective study was performed, investigating histological skin specimens of patients with a clinical diagnosis of erythroderma admitted to the Department of Dermatology of State Pediatric Medical University, Saint Petersburg, from 2001 to 2014...

Cutaneous T cell lymphomas (CTCLs) are heterogeneous, with a prognosis determined in large part by combined clinical, histopathologic, and immunophenotypic features. They are classified under the WHO-EORTC classification of primary cutaneous lymphoma. Whether or not a patient diagnosed with CTCL will experience an aggressive course may not be completely predictable; however, certain subtypes have been proven to be associated with a poor response to therapy and/or short survival. These aggressive subtypes may be diagnosed by certain histologic, immunophenotypic, and clinical features; however, there are benign lymphoproliferative disorders (LPD), such as lymphomatoid papulosis (LyP) that present with biopsy findings that simulate an aggressive lymphoma...

Cutaneous T-cell lymphomas (CTCL), especially mycosis fungoides, can be considered as a state of longstanding low-grade systemic inflammation. Many studies have focused on secondary cancers with CTCL, but information about comorbidities is limited. A total of 144 patients with CTCL at Helsinki University Central Hospital during 2005 to 2015 were studied to determine associated comorbidities and causes of death in this cohort. Compared with an age-standardized control population, the prevalence of type 2 diabetes mellitus was increased among patients with CTCL with no link to obesity...

BACKGROUND: Unilesional mycosis fungoides (UMF) and pagetoid reticulosis (PR) are variants of mycosis fungoides. Conventional therapy comprises surgical excision or radiotherapy which may be associated with long-term side effects, especially when the lesion is located at a special site like the palms and soles. Therefore, alternative treatment options are needed to treat solitary lesions in the case of UMF or PR. Recently topical photodynamic therapy (PDT) has been described to be an efficient and non-invasive therapeutical option with excellent clinical outcome...

Classic mycosis fungoides (MF) presents with patches and plaques on the trunk and proximal extremities. However, numerous clinicopathologic variants have been described, making diagnosis challenging. Here, the authors report a 21-year-old woman with immunophenotypically and molecularly confirmed MF occurring in a dermatomal distribution. Awareness of this and other rare variants of MF is critical to avoid misdiagnosis.

BACKGROUND: Mycosis fungoides (MF) is an uncommon cutaneous neoplasm in dogs. Treatment options are limited. Total skin electron therapy (TSET) has been suggested as a possible therapy for canine MF. OBJECTIVE: To describe the use of TSET as palliative treatment for MF in a dog. RESULTS: An adult dog, previously diagnosed with nonepidermolytic ichthyosis, was presented with generalized erythroderma, alopecia and erosions. Histopathology revealed a densely cellular, well-demarcated, unencapsulated infiltrate extending from the epidermis to the mid-dermis compatible with MF...

BACKGROUND: Folliculotropic mycosis fungoides (FMF) is an aggressive variant of mycosis fungoides (MF) and generally less responsive to standard skin-directed therapies (SDTs). Recent studies distinguished an indolent (early-stage FMF) and a more aggressive (advanced-stage FMF) subgroup. The optimal treatment for both subgroups needs still to be defined. OBJECTIVES: Evaluation of initial treatment results in patients with early- and advanced-stage FMF. METHODS: 203 Patients (84 early-stage, 102 advanced-stage, 17 extracutaneous FMF), included in the Dutch Cutaneous Lymphoma Registry between 1985 and 2014 were studied...
