Xeroderma pigmentosum (XP) is an autosomal recessive genetic disorder of DNA repair in which the body's normal ability to repair damage caused by ultraviolet light is deficient. This leads to a 1000-fold increased risk of cutaneous and ocular neoplasms. Ocular neoplasms occurring in XP in order of frequency are squamous cell carcinoma, basal cell carcinoma and melanoma. Malignant melanomas occur at an early age in patients with XP. We report a case of XP with massive orbital melanoma in an eight-year-old boy which is unique due to its amelanotic presentation confirmed histopathologically.
着色性干皮病(XP)是一种常染色体隐性DNA修复基因疾病,患者体内修复紫外线造成损伤的正常能力存在缺陷。这导致皮肤和眼部肿瘤的发病风险增加1000倍。XP患者眼部肿瘤的发病频率依次为鳞状细胞癌、基底细胞癌和黑色素瘤。XP患者的恶性黑色素瘤发病年龄较早。我们报告了一例8岁男孩患XP并伴有巨大眼眶黑色素瘤的病例,该病例因经组织病理学证实为无黑色素表现而具有独特性。
