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.     

Epstein–Barr virus‐associated T‐cell lymphoproliferative disorder affecting skin and lung in an elderly patient

A 70‐year‐old man presented with papular skin lesions and was diagnosed with Epstein–Barr virus (EBV)‐associated T‐cell lymphoproliferative disorder (T‐LPD). The patient showed infiltration of a large number of EBV‐encoded RNA‐positive T cells in the skin and lung, presence of EBV load in the peripheral blood, and expansion of clonal EBV‐infected γδ T cells and CD8⁺ T cells in the blood and skin, as assessed by EBV‐terminal repeat Southern blot, T‐cell receptor polymerase chain reaction and flow cytometric analyses. In the Japanese or East Asian fatal cases of EBV‐associated T/natural killer (NK)‐LPD, there are two peaks in age at death, approximately 20 years and 60 years. The former age group is associated with chronic active EBV infection (CAEBV), and the latter group typically suffers from extranodal NK/T‐cell lymphoma. Our case is characterized not only by the unique skin and lung manifestations but also the late onset age of the disease, indicating that the skin manifestation of CAEBV can be seen even in elderly patients.     

Blastoid NK cell leukemia/lymphoma with cutaneous involvement

Malignant neoplasms from natural killer (NK) cells are characterized by their positivity for CD56 and absence of monoclonal TCR gene rearrangement. Recently, they have been classified into four main types (nasal and nasal-type NK cell lymphoma, aggressive NK cell leukemia/lymphoma, and blastoid NK cell leukemia/lymphoma), based on clinical features, racial predisposition, presence of azurophilic granules, immunophenotype and association with Epstein-Barr virus (EBV) infection. A 72-year-old Caucasian man presented with a malignant neoplasm comprised of blastoid cells without azurophilic granules in the Giemsa stain, with positivity for CD2, CD4, HLA-DR, CD45 and CD56, and negativity for CD3 (surface and cytoplasmic) and CD5. In situ hybridization for EBV and PCR analysis of rearrangement of the T cell receptor gene were negative. Based on these results, a diagnosis of blastoid NK cell lymphoma was made. In this case the first clinical manifestations were the cutaneous lesions, and, although the disease was already advanced at the diagnosis, the patient responded completely to the treatment and remains asymptomatic 14 months after diagnosis.
