Case Report

Hydroa Vacciniforme-like Epstein-Barr Virus-associated Lymphoproliferative Disease in a Child

SF Xu, MP Lu


A case of hydroa vacciniforme-like Epstein-Barr virus-associated lymphoproliferative disease (LPD) in a 9-year-old boy is reported in this paper. The patient had recurrent fever for 3 months accompanied by skin lesions. Immunohistochemistry of a skin biopsy revealed that the lymphocytes were positive for T cell markers. Flow cytometric analysis of peripheral blood showed a significantly increased percentage of natural killer cells and 91% CD158i monoclonal expression. The conclusion of the skin histopathology was EBV-positive cutaneous LPD. Laboratory tests on peripheral blood and immunohistochemistry of the skin biopsy confirmed that the child was infected with Epstein-Barr virus. Note: CD158i (Official Full Name: killer cell immunoglobulin-like receptor, two domains, short cytoplasmic tail, 4)

本文報告一例9歲男孩種痘水皰病樣EB病毒相關淋巴細胞增生性疾病(LPD)。病人反復發熱3月,伴皮膚病變。皮膚活檢免疫組織化學檢測顯示淋巴細胞呈現T細胞標誌物陽性。外週血流式細胞術分析顯示自然殺傷(NK)細胞比例顯著增高,91%有CD158i單克隆表達。皮膚組織病理學結論為:EB病毒陽性皮膚 LPD。外週血實驗室檢測和皮膚活檢免疫組織化學檢查證實男孩為EB病毒感染。註:CD158i(正式全名:殺傷細胞免疫球蛋白樣受體,2個結構域,短細胞漿尾,4)
