Melanocytic nevus - Nevus Melanocytichttps://en.wikipedia.org/wiki/Nevus
Ko Nevus Melanocytic (Melanocytic nevus) he momo pukupuku melanocytic kei roto i ngā pūtau nevus. Ka puta te nuinga o ngā nevi i roto i ngā tau e rua tuatahi o te oranga o te tangata. Tata ki te kotahi i roto i ia 100 ngā pēpi ka whānau he nevi. He nevi kua riro he āhua o te neoplasm pai, engari ko te nevi whānau e kīia ana he iti te āhua kino, he hamartoma rānei, ka nui ake pea te mōrearea mō te melanoma. He porowhita, he porotītaha rānei te nevi ngawari, he iti noa iho (i waenga i te 1–3 mm), ahakoa he nui ake ētahi i te rahi o te komuru pene (5 mm). He mārō ētahi nevi.

Maimoatanga
Ka whakamahia te pokanga taiaho hei tango i ngā nevi iti. Mēnā he nui ake te rahi i te 4–5 mm, ka hiahiatia he tangohanga. I roto i ngā tamariki nohinohi, he uaua ki te tango i te nevi nui ake i te 2 mm me te kore he nawe.

I te 2022 Stiftung Warentest hua mai i Tiamana, he iti noa iho te pai o nga kaihoko ki a ModelDerm i nga korero mo te waea rongoa utu.
  • Nevus noa
  • Becker nevus ― Pakipaki; e tohuhia ana e te tipu o ngā makawe i runga i te nevus.
  • Nevus of Ota ― He kikorangi te āhua, ā, ka hohonu te wāhi o ngā pūtau nevus i te papanga kiri. I roto i tēnei take, kei runga te nevus i te conjunctiva. Ka taea te tango i te Ota nevus mā te maimoatanga laser.
  • Compound nevus ― Reke. Ka taea e ngā tohu whānau iti te tipu ki te nevi nui, me te pakeke.
  • Intradermal nevus – te ahua o te nodule puta.
  • Nevus noa. Ko ngā whakaahua e rua kei raro nei he intradermal nevus, ā, ko ngā whakaahua e toru i runga ake nei he junctional nevus.
  • Blue nevus ― Nā te hōhonutanga o te pūtau nevus, he kikorangi te āhua.
  • Intradermal nevus – Ka kitea i te mahunga.
  • Ko tēnei pikitia e tohu ana i te nevus. Heoi, mēnā he iti te whiu matua pērā, kāore pea e taea e te algorithm te tohu tika i te āhua.

Ko te Congenital melanocytic nevus he nevus melanocytic ka puta mai i te whanautanga, ā, ka puta mai rānei i ngā wāhanga whakamutunga o te kohungahunga. Ko te Nevus sebaceous, kua kiia ko te wāhi hamartomatous o te āhua pilosebaceous, kua pā ki te whanautanga. I konei, ka whakaahuahia me pēhea te whakamahi i te tikanga pinhole me te Erbium:YAG laser hei rongoā mō ngā nevi i roto i ngā turoro rerekē.
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.

Ko te melanoma he momo pūkūpuku ka puta ina mate ngā melanocytes, ngā pūtau e pā ana ki te tae kiri. Ko ngā melanocytes i ahu mai i te kōhanga neural. Ko te tikanga, ka tupu te melanoma, ehara i te kiri anake, engari i ētahi atu wāhi ka heke ngā pūtau neural crest, pērā i te kōhanga whekau me te roro. Ko te reiti oranga mō ngā turoro melanoma moata (waahanga 0) he teitei ki te 97%, engari ka tino heke ki te 10% mō te hunga kua pangia e te mate o mua (wahanga 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.
