Hydroa vacciniforme-like lymphoma (HVLL) is an Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disorder of childhood that occurs mainly in Central and South America and Asia. We present the clinicopathological features of 20 Mexican children with HVLL with a median age of 8 years at diagnosis (range, 1-15). All patients presented with skin lesions involving sun-exposed areas, but n...
BACKGROUND Epstein-Barr virus (EBV)-associated hemophagocytic lymphohistiocytosis (HLH), EBV-positive systemic T-cell lymphoproliferative disease (STLPD) of childhood, and chronic active EBV (CAEBV) infection may develop after primary EBV infection. This study reviewed the clinicopathological spectrum of EBV-associated T- and natural killer (NK)-cell LPD, including STLPD and CAEBV infection, wi...
Chronic active Epstein-Barr virus (EBV) disease (CAEBV) is a systemic EBV-positive lymphoproliferative disorder characterized by fever, lymphadenopathy, and splenomegaly. Patients with CAEBV may present with cutaneous symptoms, including hypersensitivity to mosquito bites and hydroa vacciniforme (HV)-like eruptions. HV is a rare photodermatosis characterized by vesicles and crust formation afte...
EBV-associated T/NK-cell lymphoproliferative disease (T/NK-LPD) is defined as a systemic illness characterized by clonal proliferation of EBV-infected T or NK cells. We prospectively enrolled 108 nonimmunocompromised patients with this disease (50 men and 58 women; median onset age, 8 years; age range, 1-50 years) evidenced by expansion of EBV(+) T/NK cells in the peripheral blood; these were o...
A new category, "EBV positive T-cell lymphoproliferative disorders (LPD) of childhood", was proposed in the 2008 World Health Organization's (WHO) classifications of lymphoma. This series of lymphoproliferative disorders is rare. There are two major types of this series of disorders: systemic EBV positive T-cell LPD of childhood and hydroa vacciniforme-like lymphoma (HVLL). In this study, we de...
recognised that many people are unsuitable for such treatment, particularly in the case of neurotic and highly reflex types ; so also individuals with blonde skins which do not easily pigment and easily freckle are not usually favourable subjects, and in these depression and not stimulation often follow the treatments. The same would also apply to all cases of hydroa aestivalis (recurrent summe...
To the Editor: Hydroa vacciniforme-like lymphoma (HVLL) is a rare cutaneous T-cell lymphoma recently recognized in the 2008 WHO classification of lymphomas [1]. HVLL is an Epstein–Barr virus-associated lymphoma affecting mostly children in Latin America and Asia [2,3]. HVLL, similar to hydroa vacciniforme is characterized by edema, vesicles, necrotic areas, and vacciniforme-like scars in the fa...
