Congenital nevus - Aangebore Nevus
☆ In die 2022 Stiftung Warentest-resultate van Duitsland was verbruikerstevredenheid met ModelDerm net effens laer as met betaalde telemedisyne-konsultasies.
Dit is moeilik om groot nevi op die neus heeltemal te verwyder as hulle nie in die neonatale tydperk verwyder word nie.
Aangesien dit 'n onreëlmatige vorm het, is 'n biopsie nodig.

Congenital melanocytic nevus is 'n tipe geboortemerk wat óf by geboorte óf tydens babatyd ontwikkel. Nevus sebaceous is 'n velabnormaliteit wat gebrekkige haarfollikels behels. In hierdie studie het ons 'n lasertegniek genaamd die pinhole metode met 'n Erbium: YAG laser gebruik om nevus letsels in verskeie pasiënte te behandel.
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 is 'n tipe donker velvlek wat van geboorte af daar is en word meer as 20 cm breed wanneer 'n persoon volgroeid is. Dit is regtig skaars, gebeur in minder as 1 uit elke 20 000 pasgeborenes. Al is dit skaars, is dit 'n groot probleem, want dit kan lei tot ernstige probleme soos velkanker of die brein en senuwees (neurokutane melanose) aantas. Die kans om velkanker daaruit te kry iewers in jou lewe wissel van 5 tot 10%.
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%.

In vergelyking met 'n melanositiese nevus, is aangebore melanositiese nevi gewoonlik groter in deursnee en kan oortollige hare hê. As meer as 40 cm (16 duim) met hipertrikose is, word dit soms 'n reuse harige nevus genoem.
Melanositiese nevi groei dikwels proporsioneel tot die liggaamsgrootte soos die kind volwasse word. Prominente hare vorm dikwels, veral na puberteit.
Chirurgiese uitsny is die standaard van sorg. Baie word chirurgies verwyder vir estetika. Maar groter word uitgesny vir die voorkoming van kanker. Reuse aangebore nevi het 'n groter risiko vir maligniteit degenerasie in melanoom. Skattings van transformasie na melanoom wissel van 2-42% in die literatuur.
Wanneer die letsel klein is, kan dit chirurgies verwyder word. Maar dit is baie moeilik om dit heeltemal te verwyder sonder litteken wanneer dit groot word met ouderdom.
