Epstein-Barr virus (EBV)-associated lymphoproliferations involving the skin are a rare but important group of diseases with a broad spectrum of behavior, ranging from self-limiting spontaneously resolving disorders to highly aggressive malignancies. They may be of B, T, or natural killer (NK) cell type and include EBV-positive mucocutaneous ulcer, lymphomatoid granulomatosis, EBV-positive diffuse large B-cell lymphoma, hydroa vacciniforme-like lymphoproliferative disorder, and extranodal NK/T-cell lymphoma of nasal type. Recognition and distinction of these entities is important in view of their differing prognoses and treatments. Read More

Hydroa vacciniforme (HV)-like lymphoma is a rare, usually fatal Epstein-Barr virus-driven lymphoproliferative disease affecting children from Asia, Mexico, and South America. Cutaneous manifestations imitate HV, a benign photodermatosis in which systemic symptoms are not observed, and spontaneous regression occurs later in adolescence or young adulthood. We report a case of HV-like lymphoma in a 12-year-old girl, descendent from an ancient Amazon indigenous tribe that, as far as we know, represents the second Brazilian case ever reported in the medical literature.

Chronic active Epstein-Barr virus infection (CAEBV) is a prototype of the EBV-associated T- or NK-cell lymphoproliferative diseases, which also include hypersensitivity to mosquito bites and severe-type hydroavacciniforme. The manifestations of CAEBV are often self-limiting with minimum supportive care or only prednisolone and cyclosporine A with or without etoposide. However, allogeneic hematopoietic stem cell transplantation (HSCT) is the only cure, without which patients with CAEBV die within several years. Read More

This article will focus on the cutaneous lymphoproliferative disorders associated with EBV, with an emphasis on the upcoming changes in the revised 4th Edition of the WHO classification of tumors of the hematopoietic system, many of which deal with cutaneous disorders derived from NK-cells or T-cells. Extranodal NK/T-cell lymphoma usually presents in the upper aerodigestive tract, but can involve the skin secondarily. EBV-associated T- and NK-cell lymphoproliferative disorders (LPD) in the pediatric age group include the systemic diseases, chronic active EBV infection (CAEBV) and systemic EBV+ T-cell lymphoma of childhood.

Photodermatoses are a group of skin disorders caused by abnormal reaction to ultraviolet radiation. Photodermatoses are divided into four groups: (1) immunologically mediated photodermatoses; (2) chemical- and drug-induced photodermatoses; (3) photoaggravated dermatoses; and (4) hereditary photodermatoses. This contribution discusses differences in the approach and diagnosis of pediatric and adult patients with suspected photodermatoses, focusing on immunologically mediated photodermatoses and chemical- and drug-induced photodermatoses.

Background: Hydroa vacciniforme (HV) is associated with Epstein-Barr virus (EBV) infection and a risk of transformation to lymphoma.

Methods: We retrospectively analyzed six HV cases for EBV association and transformation to HV-like T-cell lymphoma. Clinicopathologic features were reviewed and cases were assessed for EBV-encoded RNA (EBER) by in situ hybridization, double staining with immunohistochemistry and EBER and for T-cell clonality.

They are represented in large part by extranodal T/NK cell lymphomas- nasal-type or extra nasal-type, chronic lymphoproliferative disorders of T/NK cells or chronic active EBV disease, systemic EBV-positive lymphoproliferative disorders of childhood, hydroa vacciniforme-like lymphoma, hepatosplenic T-cell lymphoma and primary cutaneous gamma/delta T-cell lymphoma among others. Many T/NK cell neoplasms in this age group are derived from cells of the innate immune system, in contrast to adults where they are predominantly from the adaptive immune system. Read More

Hydroa vacciniforme-like cutaneous lymphoma is a very rare Epstein-Barr virus positive peripheral T-cell lymphoma affecting Asian and Hispanic children and young adults with a defective cytotoxic immune response to EBV predisposing to the development of the disease. We report on 2 Ecuadorian patients with papulovesicular and ulcerated crusted lesions on the face, upper and lower extremities and abdomen, with aggressive clinical course and, in one case, a fatal outcome. The histological and molecular profiles (immunohistochemistry and in situ hybridization) established a diagnosis of hydroa vacciniforme-like Epstein-Barr virus-encoded small RNAs + cutaneous T-cell lymphoma in both cases.

Over the past few decades, cumulative research has revealed that latent EBV infection may be implicated in the pathogenesis of a heterogeneous group of lymphoproliferative disorders and malignancies occurring in both immunocompetent and immunocompromised hosts. Many of these diseases have either primary or secondary cutaneous manifestations. Read More

Epstein-Barr virus (EBV) is a ubiquitous virus that has been implicated in a wide range of human diseases, many of which have mucocutaneous manifestations. As a member of the herpesviridae family, EBV causes lifelong infection by establishing latency in B lymphocytes. An intact immune response is critical in preventing progression of EBV disease, and the clinical manifestations of infection are dependent on the intricate relationship between virus and host immune system.

Hydroa vacciniforme-like lymphoma (HVL) is a rare cutaneous T-cell lymphoma that is usually seen in children of Hispanic or Asian origin. Association between chronic latent Epstein-Barr virus infection in both hydroa vacciniforme (HV) and HVL has been demonstrated and has recently been categorized by the World Health Organization as one of the Epstein Barr virus-positive lymphoproliferative disorders of childhood. Patients with HVL present with a cutaneous rash characterized by edema, blisters, ulcers, and scars mainly seen on the face and extremities that mimic HV; however, unlike in HV, the lesions tend to be extensive and deeper and are associated with severe scarring, necrosis, and systemic manifestations.

Purpose: Epstein-Barr virus (EBV) infects not only B cells but also T cells and natural killer (NK) cells, and T- and NK-cell lymphoproliferative diseases (T/NK-LPD) that are refractory to conventional chemotherapies may develop. To identify a molecular-targeted therapy for EBV-associated T/NK-LPDs, we investigated whether CC chemokine receptor 4 (CCR4) was expressed on EBV-infected T and/or NK cells and whether a humanized anti-CCR4 monoclonal antibody, mogamulizumab, was effective.

Experimental Design: CCR4 expression was examined in various cell lines. Read More

EBV-associated T- or NK-cell lymphoproliferations represent a continuous spectrum of diseases ranging from asymptomatic infection, infectious mononucleosis (IM), to clonal and malignant lymphoproliferations including systemic EBV-positive T/NK-cell lymphoproliferative disease (EBV-T/NK-LPD) of childhood and hydroa-vacciniforme-like lymphoma of the skin. The clonal diseases are more prevalent in East Asia and exhibit overlapping clinical and pathological features with chronic active EBV infection. Read More

Epstein-Barr virus (EBV) infection is usually asymptomatic and persists lifelong. Although EBV-infected B cells have the potential for unlimited proliferation, they are effectively removed by the virus-specific cytotoxic T cells, and EBV-associated lymphoproliferative disease develops only in immunocompromised hosts. Rarely, however, individuals without apparent immunodeficiency develop chronic EBV infection with persistent infectious mononucleosis-like symptoms. Read More
