Melanocytic nevus - Nev Melanositikhttps://en.wikipedia.org/wiki/Nevus
Nev Melanositik (Melanocytic nevus) se yon kalite timè melanocytic ki gen selil nevus. Majorite nevi parèt pandan de premye deseni lavi yon moun. Avèk apeprè youn nan chak 100 ti bebe ki fèt ak nevi. Nevi akeri yo se yon fòm neoplasm benign, pandan y ap nevi konjenital yo konsidere kòm yon malformation minè oswa hamartom epi yo ka nan yon pi gwo risk pou melanom. Nevus Benign yo sikilè oswa oval epi yo anjeneral piti (souvan ant 1-3 mm), menm si kèk ka pi gwo pase gwosè yon gonm kreyon tipik (5 mm). Gen kèk nevi ki gen cheve.

○ Tretman
Operasyon lazè yo souvan fè pou retire kosmetik ti nevi. Si gwosè a pi gwo pase 4-5 mm, yo ka mande yon eksizyon chirijikal. Nan timoun piti, yon nevus ki pi gwo pase 2 mm nan gwosè souvan difisil yo dwe konplètman retire san sikatris.

  • Nòmal nevus
  • Becker nevus ― Zepòl; karakterize pa kwasans lan nan cheve sou nevus la.
  • Nevus of Ota ― Parèt ble akòz kote gwo twou san fon selil nevus yo nan kouch po a. Nan ka pasyan sa a, nevus la sitiye sou konjonktiv la. Ota nevus ka retire atravè tretman lazè.
  • Compound nevus ― Boutèy. Ti mak nesans ka grandi nan gwo nevi ak laj.
  • Intradermal nevus ― Fòm yon nodil ki vle pèse anvlòp la.
  • Nòmal nevus. De foto ki anba yo se intradermal nevus, ak twa foto ki anlè yo se junctional nevus.
  • Blue nevus ― Akòz kote selil nevus yo byen fon, li parèt ble.
  • Intradermal nevus ― Li souvan obsève sou po tèt la.
  • Foto sa a endike yon blesi nevus. Sepandan, si blesi prensipal la piti tankou sa a, algorithm la ka pa kapab byen predi kondisyon an.

Congenital melanocytic nevus se yon nevus melanocytic ki swa prezan nan nesans oswa ki parèt pandan dènye etap yo nan anfans. Nevus sebase yo te dekri kòm kote hamartomatous nan yon inite pilosebaceous anbriyolojik ki defektye. Isit la, nou dekri kijan nou itilize teknik pinhole ak yon lazè Erbium:YAG pou trete blesi nevi nan diferan pasyan yo.
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.

Yon melanom se yon kalite timè ki fòme lè melanosit, selil ki responsab koulè po a, vin kansè. Melanosit soti nan krèt neral la. Sa vle di ke melanom ka devlope pa sèlman sou po a, men tou nan lòt zòn kote selil krèt neral imigre, tankou aparèy gastwoentestinal la ak sèvo. Pousantaj siviv pou pasyan ki gen melanom nan etap bonè (etap 0) wo nan 97%, pandan ke li desann anpil nan apeprè 10% pou moun ki dyagnostike ak maladi nan etap avanse (etap 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.
