- 关于局部EB,特别是 Dystrophic EB (DEB) 的脱发的文献是有限的.
- 在DEB中很少报告有痕和无痕的脱发.
研究的目的:
- 在患有局部发性EB的患者中表征脱发.
- 为了研究DEB.EB中脱发的组织学特征.
- 为了区分与DEB相关的脱发症与其他潜在的原因,如状.
主要方法:
- 一个58岁的女性病例介绍,她患有前肢DEB和COL7A1突变.
- 临床检查头皮毛发稀疏和相关的皮肤发现.
- 使用垂直和水平切口进行头皮活检的组织病理学分析.

01:19Clinical Applications of Epidermal Stem Cells
3.2K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

5.7K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
