Melanocytic nevushttps://en.wikipedia.org/wiki/Nevus
Melanocytic nevus ndi mtundu wa chotupa cha melanocytic chomwe chili ndi nevus cell. Ambiri a nevi amawonekera m'zaka makumi awiri zoyambirira za moyo wa munthu. Pafupifupi mwana mmodzi mwa ana 100 aliwonse amabadwa ndi nevi. Nevi yopezeka ndi mtundu wina wa neoplasm yoyipa, pomwe congenital nevi imawonedwa ngati cholakwika chaching'ono kapena hamartoma ndipo ikhoza kukhala pachiwopsezo chachikulu cha melanoma. Benign nevus ndi yozungulira kapena yozungulira ndipo nthawi zambiri imakhala yaying'ono (nthawi zambiri imakhala pakati pa 1-3 mm), ngakhale ina imatha kukhala yayikulu kuposa kukula kwa chofufutira cha pensulo (5 mm). Nevi ena ali ndi tsitsi.

○ Machiritso
Opaleshoni ya laser nthawi zambiri imachitika kuti achotse nevi yaying'ono. Ngati kukula kwake kuli kokulirapo kuposa 4-5 mm, kudulidwa kwa opaleshoni kungafunike. Mwa ana ang'onoang'ono, nevus yokulirapo kuposa 2 mm kukula imakhala yovuta kuchotsedwa kwathunthu popanda zipsera.

  • Normal nevus
  • Becker nevus ― Phewa; yodziwika ndi kukula kwa tsitsi pa nevus.
  • Nevus of Ota ― Amawoneka abuluu chifukwa chakuzama kwa ma cell a nevus mu dermal layer. Pankhani ya wodwala uyu, nevus ili pa conjunctiva. Ota nevus ikhoza kuchotsedwa kudzera mu chithandizo cha laser.
  • Compound nevus ― Buttock. Zizindikiro zazing'ono zobadwa zimatha kukula mpaka nevi yayikulu ndi zaka.
  • Intradermal nevus ― Maonekedwe a nodule yotuluka.
  • Normal nevus. Zithunzi ziwiri pansipa ndi intradermal nevus, ndipo zithunzi zitatu pamwambapa ndi junctional nevus.
  • Blue nevus ― Chifukwa chakuya kwa ma cell a nevus, amawoneka abuluu.
  • Intradermal nevus ― Nthawi zambiri imawonedwa pamutu.
  • Chithunzichi chikuwonetsa chotupa cha nevus. Komabe, ngati chotupa chachikulu ndi chaching'ono chonga ichi, algorithm sangathe kuneneratu molondola mkhalidwewo.

Congenital melanocytic nevus ndi melanocytic nevus yomwe imakhalapo pakubadwa kapena imawonekera kumapeto kwa ubwana. Nevus sebaceous yafotokozedwa kuti ndi malo osasinthika a gawo la embryologically defective pilosebaceous unit. Apa, tikufotokozera momwe tidagwiritsira ntchito njira ya pinhole ndi Erbium:YAG laser kuti tichite zilonda za nevi mwa odwala osiyanasiyana.
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.

Melanoma ndi mtundu wa chotupa chomwe chimapanga pamene ma melanocyte, maselo omwe amachititsa khungu, amakhala ndi khansa. Ma melanocyte amachokera ku neural crest. Izi zikutanthauza kuti melanomas imatha kukula osati pakhungu lokha komanso m'malo ena omwe maselo a neural crest amasamukira, monga m'mimba ndi ubongo. Kupulumuka kwa odwala omwe ali ndi melanoma yoyambirira (gawo 0) ndipamwamba kwambiri pa 97%, pomwe amatsika kwambiri mpaka pafupifupi 10% kwa omwe amapezeka ndi matenda apamwamba (siteji 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.
