Congenital melanocytic nevus 是一种黑素细胞痣,要么在出生时出现,要么在婴儿后期出现。皮脂腺痣被描述为胚胎缺陷的毛囊皮脂腺单位的错构瘤位点。在这里,我们描述了如何使用针孔技术和 Erbium:YAG 激光来治疗不同患者的痣病变。 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区域(例如胃肠道和大脑)中生长。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 10% 左右。 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
激光手术通常用于美容去除小痣。如果尺寸大于4-5毫米,可能需要手术切除。对于幼儿来说,大于2毫米的痣通常很难完全去除而不留下疤痕。
