概括

黑色素瘤/低黑色素瘤 (AHM) 很难诊断,特别是当它们很薄时. 薄型AHM通常发生在肤浅的个体中,并且具有独特的临床特征,与较厚的病变的皮肤学区别有限.

科学领域:

皮肤病学皮肤病学
在瘤学瘤学.
病理学病理学病理学

背景情况:

黑色素瘤/低黑色素瘤 (AHM) 占皮肤黑色素瘤的2-8%.
由于它们的非特异性临床外观和缺乏明显的皮肤学特征,特别是在较薄的病变中,AHM会带来诊断挑战.

研究的目的:

评估薄型AHM的临床病理学和皮肤学特征.
确定有助于了解和诊断薄AHM的关键特征.

主要方法:

在Breslow厚度的基础上,对153个AHM的队列进行了分层,分为薄 (≤1.00毫米) 和厚 (>1.00毫米) 组.
利用模式分析对病变标准进行主观皮肤镜评估.

主要成果:

薄型AHM在红发和II型照片的人群中更为普遍,经常发生在干部.
患有薄型AHM的患者患有多重原发性黑色素瘤的发病率更高.
皮肤镜分析显示,薄型和厚型AHM之间没有显著差异,除了薄型病变中残留网膜的频率更高.

结论:

薄型AHM与较低的光型和红发有关,可能与黑素减少的防晒作用有关.
干部是薄型AHM的常见地点,与间歇性阳光照射相关.
在薄型AHM患者中,多重原发性黑色素瘤的发生率增加可能反映了遗传倾向和加强皮肤病监测.

Skin Cancer

Skin Cancer

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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Changes in Skin Color: Clinical Perspectives

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
