Congenital nevus - Tug'Ma Nevus
☆ Germaniyaning 2022 yilgi Stiftung Warentest natijalariga ko'ra, iste'molchilarning ModelDermdan qoniqish darajasi pullik teletibbiyot maslahatlariga qaraganda bir oz pastroq bo'lgan.
Neonatal davrda olib tashlanmasa, burundagi katta nevuslarni butunlay olib tashlash qiyin.
Noto'g'ri shaklga ega bo'lgani uchun biopsiya zarur.

Congenital melanocytic nevus - tug'ilish paytida yoki chaqaloqlik davrida paydo bo'ladigan tug'ilish belgisi turi. Nevus sebaceous - nuqsonli soch follikulalarini o'z ichiga olgan teri anomaliyasi. Ushbu tadqiqotda biz turli bemorlarda nevus lezyonlarini davolash uchun Erbium: YAG lazer bilan pinhole usuli deb ataladigan lazer texnikasidan foydalandik.
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.

Giant congenital melanocytic nevus - teridagi qora dog'ning bir turi bo'lib, u tug'ilishdan boshlab mavjud bo'lib, odam to'liq o'sganida kengligi 20 sm dan oshadi. Bu haqiqatan ham kamdan-kam uchraydi, har 20 000 yangi tug'ilgan chaqaloqdan 1 tasida sodir bo'ladi. Kamdan kam bo'lsa ham, bu juda muhim, chunki teri saratoni kabi jiddiy muammolarga olib kelishi yoki miya va nervlarga ta'sir qilishi mumkin (neyrokutan melanoz) . Hayotingiz davomida teri saratoni bilan kasallanish ehtimoli 5 dan 10% gacha.
Giant congenital melanocytic nevus is usually defined as a melanocytic lesion present at birth that will reach a diameter ≥ 20 cm in adulthood. Its incidence is estimated in <1:20,000 newborns. Despite its rarity, this lesion is important because it may associate with severe complications such as malignant melanoma, affect the central nervous system (neurocutaneous melanosis). The estimated lifetime risk of developing melanoma varies from 5 to 10%.

Melanotsitik nevus bilan solishtirganda, tug'ma melanotsitik nevuslar odatda diametri kattaroq va ortiqcha sochlarga ega bo'lishi mumkin. Agar gipertrikoz bilan 40 sm (16 dyuym) dan ortiq bo'lsa, u ba'zan gigant tukli nevus deb ataladi.
Melanotsitik nevuslar ko'pincha bolaning etukligida tana hajmiga mutanosib ravishda o'sadi. Ko'zga ko'ringan tuklar ko'pincha, ayniqsa balog'at yoshidan keyin hosil bo'ladi.
Jarrohlik yo'li bilan olib tashlash standart tibbiy yordamdir. Ko'pchilik estetika uchun jarrohlik yo'li bilan olib tashlanadi. Ammo kattaroqlari saratonning oldini olish uchun kesiladi. Gigant tug'ma nevuslar melanomaga yomon xulqli degeneratsiya xavfi yuqori. Adabiyotda melanomaga aylanish baholari 2-42% gacha o'zgarib turadi.
Zarar kichik bo'lsa, uni jarrohlik yo'li bilan olib tashlash mumkin. Ammo, yoshi bilan kattalashganda, uni chandiqsiz butunlay olib tashlash juda qiyin.
