Congenital melanocytic nevus 是一种黑素细胞痣,可在出生时或婴儿期后出现。皮脂腺痣被认为是胚胎期毛囊皮脂腺单位的错构瘤性病灶。本文描述了如何使用针孔技术和 Erbium:YAG 激光治疗不同患者的痣性病变。 Congenital melanocytic nevus (CMN) is a melanocytic nevus that is either present at birth or appears during the latter stages of infancy. Nevus sebaceous has been described as the hamartomatous locus of an embryologically defective pilosebaceous unit. Here, we describe how we used the pinhole technique with an erbium-doped yttrium aluminium garnet (erbium : YAG) laser to treat nevi lesions in different patients.
黑色素瘤是一种肿瘤,当黑色素细胞(负责肤色的细胞)癌变时形成。黑色素细胞起源于神经嵴,这意味着黑色素瘤不仅可以在皮肤上生长,还可以在神经嵴细胞迁移的其他部位(例如胃肠道和大脑)中出现。早期黑色素瘤(0期)患者的生存率高达97%,而晚期(IV期)患者的生存率则大幅下降至约10%。 A melanoma is a tumor produced by the malignant transformation of melanocytes. Melanocytes are derived from the neural crest; consequently, melanomas, although they usually occur on the skin, can arise in other locations where neural crest cells migrate, such as the gastrointestinal tract and brain. The five-year relative survival rate for patients with stage 0 melanoma is 97%, compared with about 10% for those with stage IV disease.
○ 治疗
激光手术常用于美容性去除小痣。若痣直径大于 4–5 毫米,可能需要手术切除。对于幼儿而言,直径超过 2 毫米的痣往往难以在不留下疤痕的情况下完全去除。
