Hydroa vacciniforme-like Epstein-Barr virus-associated monoclonal T-lymphoproliferative disorder in a child

Hydroa vacciniforme (HV) is a chronic photosensitivity disorder induced by ultraviolet radiation. Hydroa vacciniforme-like lymphoma is a rare cutaneous T-cell lymphoma occurring mainly in childhood. Recent studies have demonstrated an association between chronic latent Epstein-Barr virus (EBV) infection and both the benign skin disorder and the lymphoma. The authors report a 6-year-old boy with chronic EBV infection, HV-like skin eruptions, and chronic hepatitis. Histopathologic examination of a skin biopsy specimen demonstrated epidermal ballooning degeneration and dense superficial and deep perivascular and periappendageal lymphoid cell infiltrates extending to the fat lobules. Some blood vessels in the deep plexus were infiltrated by predominantly CD4+ and TIA-1+ cytotoxic T cells. The EBV genomes were found within tissue from three skin biopsies and peripheral blood cells. Monoclonal T-cell receptor gene rearrangement was present in skin biopsy specimens. Although no lymphoma has been found during 2 years of follow-up treatment, the possibility of lymphoma developing out of the current smoldering stage is of concern. The clinical manifestations of lymphoproliferative disorder and chronic active EBV infection are discussed.     

Hydroa Vacciniforme-Like Lymphoproliferative Disorder in Korea: Prognostic Implication of Clinical Signs and Whole Blood Epstein-Barr Virus DNA

BackgroundHydroa vacciniforme-like lymphoproliferative disorder (HVLPD) is rare Epstein-Barr virus (EBV)-associated disease. The classic form of HVLPD is a self-resolving disease, whereas the systemic form can progress to malignant lymphoma, resulting in fatal outcomes. However, the prognostic factors remain unclear.ObjectiveThis study aimed to evaluate the clinical characteristics of HVLPD and the association between whole blood EBV DNA and clinical outcomes.MethodsWe retrospectively reviewed our 25-year experience involving 11 patients with HVLPD from a single tertiary center in South Korea and evaluated the clinical characteristics of HVLPD and the correlation between whole blood EBV DNA and clinical outcomes.ResultsOf the total 11 patients, 54.5% (6/11) manifested classic HVLPD that resolved with conservative treatment, while 45.5% (5/11) patients had systemic HVLPD, four of whom died of progressive disease or hemophagocytic syndrome. Five patients with systemic HVLPD manifested severe skin lesions such as prominent facial edema, deep ulcers and necrotic skin lesions involving sun-protected areas. Median EBV DNA levels at initial diagnosis were higher in three dead patients than in those alive (2,290 vs. 186.62 copies/µl).ConclusionWhen EBV DNA levels were high, patients showed severe skin lesions and when EBV DNA levels were low, skin lesions tended to improve. Thus, patients with high EBV DNA levels showed an increased risk of severe skin lesions and disease progression.

Artificial reproduction of atypical hydRoa vacciniforme caused by latent EpStein-Barr virus infection

BACKGROUND: Cases of hydroa vacciniforme-like eruptions caused by latent Epstein-Barr virus (EBV) infection have been reported in Asia and Mexico, some of which progressed to lymphoproliferative disorders. The precise clinical features of the disease are not, however, clear. METHODS: We performed an artificial provocation test with repeated exposures of ultraviolet A (UVA) and UVB in an 8-year-old Korean girl who had severe hydroa vacciniforme-like skin eruptions on exposed areas. RESULTS: The patient showed features of latent EBV infection serologically, and an in situ hybridization study indicated that most infiltrating mononuclear cells in the dermis were positive for EBV. After three exposures to UVA irradiation with a total dose of 90 J/cm2, erythema and vesicles appeared on the UVA-irradiated site but not on the UVB-irradiated site. CONCLUSIONS: Atypical hydroa vacciniforme caused by latent EBV infection could be reproduced by repeated UVA irradiation. Further study on the photo-protection would be necessary to prevent its progression to lymphoproliferative malignancies.

Hydroa vacciniforme is associated with increased numbers of Epstein-Barr virus-infected γδT cells

Hydroa vacciniforme (HV) is a rare photosensitivity disorder of childhood associated with Epstein-Barr virus (EBV)(+) T-cell infiltration. We have summarized clinical manifestations of HV, and analyzed EBV(+) T-cell subsets as well as EBV DNA load in lymphocyte fractions, in comparison with hypersensitivity to mosquito bites (HMB), an EBV-associated T/natural killer (NK) lymphoproliferative disorder. We found that 31 of 33 (93.9%) HV lesions were composed of EBV(+) T cells and reactive EBV(-) cytotoxic T cells, without significant CD56(+) cell infiltration, whereas many CD56(+) cells were present in 8 of 9 (88.9%) HMB lesions. Of 13 (20.6%) HMB patients with or without HV, 12 (92.3%) showed increased percentages (>32%) of NK cells in the peripheral blood, whereas in the 16 patients with HV alone, 14 (87.5%) showed no increase. Of the 11 HV patients, 10 (90.9%) had increased percentages (>5%) of circulating γδT cells, with a mean value of 15.7 ± 2.9%, and the γδT-cell fractions contained larger amounts of EBV DNA than non-γδT-cell fractions. A triple-labeling method revealed that all three HV patients examined had increased percentages of EBER(+), T-cell receptor (TCR)γδ(+), and TCRαβ(-) cells. Our observations indicate that HV is associated with increased numbers of EBV(+) γδT cells, whereas HMB is associated with EBV(+) NK cells.     

Hydroa vacciniforme-like lymphoma: a case report and literature review

Hydroa vacciniforme (HV) is a photosensitivity disorder in childhood characterized by recurrent vacciniform vesicles, necrotic ulcers, and scars on sun-exposed areas. HV-like lymphoma is a rare variant of cutaneous T-cell lymphoma. HV, atypical HV and HV-like lymphoma belong to the spectrum of Epstein-Barr virus (EBV)-associated lymphoproliferative disorders. We report a fatal case of HV-like lymphoma in a 31-year-old man with a 16-year history of recurrent vacciniform papulovesicular eruption with crusts and scarring. The rash initially was confined to the sun-exposed areas. Histopathology revealed focal necrosis of the epidermis and subjacent dermis with a superficial lymphocytic infiltrate, consistent with HV. Toward the end of the clinical course, the skin lesions became persistent and spread to nonsun-exposed areas. Repeated biopsies revealed epidermal necrosis with infiltration of CD4+, CD56- lymphocytes in the dermis, some with atypical nuclei, and small blood vessel vasculitis. EBV-encoded RNA (EBER-1)-positive lymphocytes were detected. Progression of his skin lesions was associated with colon ulcers, gingival ulcers, fever, splenomegaly, leukopenia and thrombocytopenia. EBER-1-positive lymphocytes were detected in all biopsy specimens, including the skin, gingiva, and bone marrow; the last also showed infiltrate of atypical lymphocytes with T-cell receptor-γ gene rearrangement. The pathogenic role of UV-irradiation is discussed.
