Melanocytic nevus - Nevus Melanositikhttps://en.wikipedia.org/wiki/Nevus
Nevus Melanositik (Melanocytic nevus) minangka jinis tumor melanocytic sing ngandhut sel‑sel nevus. Mayoritas nevi katon sajrone rong dekade pisanan urip manungsa. Kira‑kira siji saka saben 100 bayi lair kanthi nevi. Nevi sing dipikolehi minangka wangun neoplasma jinak, dene nevi kongenital dianggep minangka malformasi cilik utawa hamartoma lan bisa uga duwe risiko luwih dhuwur kanggo melanoma. Nevus jinak iku bunder utawa oval lan biasane cilik (biasane antara 1‑3 mm), sanajan sawetara bisa luwih gedhe tinimbang ukuran penghapus potlot (5 mm). Sawetara nevi duwe rambut.

○ Pengobatan
Operasi laser biasane ditindakake kanggo mbusak nevi cilik kanthi tujuan kosmetik. Yen ukurane luwih gedhe tinimbang 4‑5 mm, eksisi bedah bisa uga dibutuhake. Ing bocah cilik, nevus sing ukurane luwih gedhe tinimbang 2 mm asring angel dicopot tanpa ninggalake parut.

  • Nevus normal
  • Becker nevus — Pundhak; ditandai dening wutah rambute ing nevus.
  • Nevus of Ota ― Katingal biru amarga lokasi sel nevus sing ana ing lapisan kulit jero. Ing kasus pasien iki, nevus dumunung ing conjunctiva. Nevus of Ota bisa diilangi kanthi perawatan laser.
  • Compound nevus – bokong. Tandha lair cilik bisa tuwuh dadi nevi gedhe nalika umur mundhak.
  • Intradermal nevus — wujudipun buntelan ingkang njedhul.
  • Nevus normal. Foto loro ing ngisor iki yaiku intradermal nevus, dene foto telu ing ndhuwur yaiku junctional nevus.
  • Blue nevus ― Amarga lokasine sel nevus sing jero, katon biru.
  • Intradermal nevus — biasane ditemokake ing kulit sirah.
  • Gambar iki nuduhake lesi nevus. Nanging, yen lesi utama cilik kaya iki, algoritma kasebut bisa uga ora prédhiksi kondisi kasebut kanthi akurat.

Congenital melanocytic nevus minangka nevus melanositik sing ana nalika lair utawa katon ing tahap pungkasan bayi. Nevus sebaceous diterangake minangka lokus hamartomatous saka unit pilosebaceous sing cacat embriologis. Ing kene, kita nerangake cara nggunakake teknik pinhole kanthi laser Erbium:YAG kanggo nambani lesi nevi ing macem‑macem pasien.
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 minangka jinis tumor sing dibentuk saka melanosit, sel sing tanggung jawab kanggo warna kulit, lan dadi kanker. Melanosit asalé saka sel puncak saraf. Iki tegese melanoma bisa berkembang ora mung ing kulit, nanging uga ing wilayah liya ing ngendi sel‑sel puncak saraf migrasi, kayata saluran pencernaan lan otak. Tingkat kelangsungan urip kanggo pasien melanoma tahap awal (tahap 0) dhuwur, nganti 97%, nanging mudhun sacara signifikan nganti udakara 10% kanggo wong sing didiagnosis penyakit tahap lanjut (tahap 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.
