摘要
皮肤癌可来源于任何皮肤结构。比如从来源于表皮成分(基底细胞癌和鳞状细胞癌)及黑素细胞(恶性黑素瘤),到少见情况下来源于血管(血管肉瘤),结缔组织(如隆突皮肤纤维肉瘤)和其他皮肤附属结构(如微囊性附属器癌)。皮肤也可被淋巴瘤细胞浸润(T细胞性和B细胞性)以及其他系统恶性疾病也可侵犯到皮肤。
Cancer may arise from any structure in the skin.Malignant tumours range from the common epidermally dervied malignancies(basal cell carcinoma and squamous cell carcinoma),through malignant melanoma(derived from melanocytes),to the rarer eancers of blood vessels(e.g.angiosarcoma),connective tissue(e.g.dermatofibrosarcoma protuberans)and other adnexal structures(e.g.microcystic adnexal carcinoam).The skin may also be infiltrated by lymphoma cells(T and cell)and by secondary malignant deposits.
