The authors present a case of Merkel cell carcinoma (MCC) with unique immunohistochemical staining characteristics. A 57-year-old woman presented with a firm 0.3 cm tan papule on her left nasal-labial fold that was reportedly increasing in size and bleeding. She had a history of multiple head and neck actinic keratoses, papillary thyroid carcinoma, and a family history of an uncle with melanoma. The clinical differential diagnosis was "non-melanoma skin cancer." Histological examination showed a markedly atypical-appearing basaloid neoplasm, present mostly in the dermis, with focal pagetoid spread into the epidermis...

Extracorporeal photopheresis (ECP) has been used for over 35 years in the treatment of erythrodermic cutaneous T-cell lymphoma (CTCL) and over 20 years for chronic and acute graft-versus-host disease (GvHD) and solid organ transplant rejection. ECP for CTCL and GvHD is available at specialised centres across the UK. The lack of prospective randomised trials in ECP led to the development of UK Consensus Statements for patient selection, treatment schedules, monitoring protocols and patient assessment criteria for ECP...

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...

Jacqueline M Junkins-Hopkins Md
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...

Histone deacetylases (HDACs) play a crucial role in the remodeling of chromatin, and are involved in the epigenetic regulation of gene expression. In the last decade, inhibition of HDACs came out as a target for specific epigenetic changes associated with cancer and other diseases. Until now, more than 20 HDAC inhibitors (HDACIs) have entered clinical studies, and some of them (e.g., vorinostat, romidepsin) have been approved for the treatment of cutaneous T-cell lymphoma. This review provides an overview of current knowledge, progress, and molecular mechanisms of HDACIs, covering a period from 2011 until 2015...

BACKGROUND AND OBJECTIVES: Intralesional injection of anti-CD20 antibody (rituximab) has been described as effective therapeutic option for patients with indolent primary cutaneous B-cell lymphoma (PCBL). To date, no parameters that reproducibly predict favorable clinical outcome of this treatment have been identified. The study aims to evaluate the clinical response and adverse effects as well as patients' self-perception of intralesional injection of anti-CD20 antibody for treatment of indolent PCBL compared to other treatment modalities...

BACKGROUND: Chronic actinic dermatitis (CAD) is a recurrent photosensitive dermatitis that occurs predominantly on sun-exposed areas with unknown etiology. In severe cases, it may present with erythroderma, which is clinicopathologically analogous to cutaneous T-cell lymphoma. Typically, inflammatory infiltrates in the skin lesions are mainly CD8(+) reactive T cells. However, hematologic characteristics of CAD have not been fully elucidated. METHODS: Twenty patients with CAD ranging in age from 45 to 86 years (median, 64), including 17 males and three females (M/F ratio, 5...

Staphylococcal enterotoxins have been shown to promote lymphoma-associated immune dysregulation. This study examined changes in the skin microbiome of parapsoriasis compared with intact skin. Swab microbiome specimens were taken of the parapsoriasis lesions of 13 patients. Control samples were taken from contralateral healthy sides of the body. Microbiotas were characterized by sequencing the V1-V3 region of the 16S ribosomal RNA bacterial genes on the Illumina MiSeq platform. The most common genera in the microbiome data were Propionibacterium (27...

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...

Anaplastic large cell lymphomas (ALCLs) are CD30-positive T-cell non-Hodgkin lymphomas that bear chromosomal rearrangements of the TP53 homologue, TP63, in a subset of cases that demonstrate aggressive clinical behavior. In the present study, we examined the relationship between p63 protein expression by immunohistochemistry and the results of fluorescence in situ hybridization (FISH) using TP63 probes in 116 ALCLs. We also determined the relative expression of full-length TAp63 and truncated ΔNp63 isoforms (e...

Vasculitis is a remarkable presentation of the extrahepatic manifestations of HCV. According to the presence or absence of cryoglobulins it is subdivided into two main types: cryoglobulinemic vasculitis and non cryoglobulinemic vasculitis based on the attribution of vasculitis to serum cryoglobulins as a pathogenic factor. The attribution of cryoglobulinemia to HCV represents a success story in the history of immunology, microbiology, and clinical medicine. HCV can bind to and invade lymphocytes, consequently triggering an immune response through different mechanisms...

Patients with neurofibromatosis type 1 (NF-1) have a well-known predisposition for certain types of malignancies, including lymphoproliferative disorders. Cutaneous T-cell lymphoma (CTCL) has been reported in patients with NF-1, although it is considered a rare entity in this subset of patients. Cutaneous follicular helper T-cell lymphoma (CTFHCL) is a recently emerged rare subtype of CTCL with peculiar clinical and histopathological features and represents a diagnostic and therapeutic challenge. Only a few cases of CTFHCL have been reported in the literature...
