Melanocytic nevushttps://en.wikipedia.org/wiki/Nevus
Melanocytic nevus o se ituaiga o tuma melanocytic e iai sela nevus. Ole tele ole nevi e aliali mai ile luasefulu tausaga muamua ole olaga ole tagata. E tusa ma le tasi mai le 100 pepe e fananau mai ma nevi. O nevi maua o se ituaiga o neoplasm mama, a'o nevi fanau mai e manatu o se fa'aletonu la'ititi po'o le hamartoma ma atonu e maualuga atu le lamatiaga mo le melanoma. O nevus ga'o e lapotopoto pe lapotopoto ma e masani lava ona la'ititi (masani i le va o le 1-3 mm), e ui o nisi e mafai ona lapopo'a nai lo le lapisi masani o penitala (5 mm). O nisi nevi e iai lauulu.

○ Togafiti
O le taotoga laser e masani ona faia e aveese ai nevi laiti. Afai ole lapo'a e sili atu i le 4-5 mm, e ono mana'omia se tipi tipitipi. I tamaiti laiti, o se nevus e sili atu i le 2 mm le tele e masani ona faigata ona aveese atoa e aunoa ma se maʻila.

  • Nevus masani
  • Becker nevus ― Tau‘au; faʻaalia i le tuputupu aʻe o lauulu i luga o le nevus.
  • Nevus of Ota ― E foliga lanumoana ona o le loloto o le nofoaga o sela nevus i totonu o le dermal layer. I lenei maʻi, o le nevus o loʻo i luga o le conjunctiva. Ota nevus e mafai ona aveese e ala i togafitiga laser.
  • Compound nevus ― Tonu. Fa'ailoga fanau laiti e mafai ona tupu i nevi tetele pe a matutua.
  • Intradermal nevus ― Le foliga o se nodule fa'aoso.
  • Nevus masani. O ata e lua o loʻo i lalo o le intradermal nevus, ma o ata e tolu o loʻo i luga o le junctional nevus.
  • Blue nevus ― Ona o le loloto o le nofoaga o sela nevus, e foliga mai e lanumoana.
  • Intradermal nevus ― E masani ona matauina i luga o le ulu.
  • O lenei ata o loʻo faʻaalia ai le nevus lesion. Ae peitaʻi, afai e laʻititi le liona autu e pei o lenei, atonu e le mafai e le algorithm ona vaʻai saʻo le tulaga.

Congenital melanocytic nevus o se nevus melanocytic o lo'o i ai i le taimi na fanau mai ai pe fa'aalia fo'i i vaega mulimuli o le pepe. Nevus sebaceous ua faamatalaina o le nofoaga hamartomatous o se vaega pilosebaceous faaletonu embryologically. O iinei, matou te faʻamatalaina pe faʻapefea ona matou faʻaogaina le pinhole technique i se Erbium:YAG laser e togafitia ai nevi lesions i gasegase eseese.
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.

O le melanoma o se ituaiga tuma e tupu pe a avea melanocytes, sela e nafa ma le lanu o le paʻu, ma kanesa. Melanocytes e afua mai i le neural crest. O lona uiga e le gata e mafai ona tupu le melanomas i luga o le paʻu ae faʻapea foʻi i isi vaega o loʻo feoai ai sela o le neural crest, e pei o le gastrointestinal tract ma le faiʻai. O le fua faatatau o le ola mo tagata mamaʻi e maua i le amataga o le melanoma (laasaga 0) e maualuga i le 97%, ae e pa'ū tele i le tusa ma le 10% mo i latou e maua i le tulaga maualuga (tulaga IV) .
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.
