皮肤基底细胞癌

定义

基底细胞癌或BCC是人类最常见的恶性肿瘤。据认为，BCC产生于表皮基底层的多能细胞，或毛囊较少见。BCCs通常发生在长期暴露在阳光下区域，表现为头部和颈部缓慢扩大的红色丘疹、斑块或结节，尽管浅表变体常常位于躯干。BCCs经常溃烂并结痂。虽然很少转移，但如果被忽视或治疗不当，特别是硬化型或浸润性亚型，会造成严重的局部破坏和畸形。

Basal cell carcinoma or BCC is the most common malignancy in humans. It is believed that BCCs arise from pluripotential cells in the basal layer of the epidermis or, less commonly, hair follicle. BCCs typically occur in areas of chronic sun exposure and present as slowly enlarging reddish papules, plaques or nodules on the head and neck, although the superficial variant is often located on the trunk. BCCs frequently ulcerate and become crusted. Although they rarely metastasize, they can cause significant local destruction and disfigurement if neglected or inadequately treated, particularly if of the sclerosing or infiltrative subtype.
