Congenital melanocytic nevus 是一種黑色素細胞痣,要麼在出生時出現,要麼在嬰兒期稍後出現。皮脂腺痣被描述為胚胎缺陷的毛囊皮脂腺單位的錯構瘤位點。在此,我們說明如何利用針孔技術與 Erbium:YAG 雷射治療不同患者的痣狀病變。 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.
黑色素瘤是一種腫瘤,當負責膚色的黑色素細胞發生癌變時形成。黑色素細胞起源於神經嵴,這意味著黑色素瘤不僅可以在皮膚上生長,還可能出現在神經嵴細胞遷移的其他部位,如胃腸道和大腦。早期黑色素瘤(0 期)患者的存活率高達 97%,而晚期(IV 期)患者的存活率則降至約 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.
○ 治療
雷射手術常用於美容性去除小痣。若痣直徑超過 4–5 mm,可能需要外科切除。對於幼兒而言,直徑超過 2 mm 的痣通常難以在不留下疤痕的情況下完全去除。
