作者报告发生在眼脸皮肤表面(6例)和结膜(23例)的恶性雀斑(lentigo maligna),恶性雀斑黑瘤(lentigo maligna melanoma)和浅层扩张性黑瘤(superficial spreadingmelanoma)的病例。当这些皮肤性眼脸病变扩张至结膜时,它们的特殊组织学特征保持不变。在本组中,皮肤黑瘤三种最常见类型中有二型,浅层扩张性黑瘤和恶性雀斑黑瘤。这是有上皮内成分的两型,往往彼此混淆。结膜并有恶性黑瘤无放射状生长期和恶性黑瘤有未分类的放射状生长期二类。
The authors report cases of lentigo maligna, lentigo maligna melanoma, and superficial spreading melanoma on the ocular surface (6 cases) and conjunctiva (23 cases). When these skin ocular facial lesions expand to the conjunctiva, their specific histological features remain unchanged. In this group, the three most common types of cutaneous melanoma are type II, shallow dilating melanoma and malignant freckles melanoma. There are two types of intraepithelial components that are often confused with each other. Conjunctiva and malignant melanoma There is no radial growth phase and malignant melanoma with unclassified radial growth phases.
