Yn 'e 2022 Stiftung Warentest-resultaten út Dútslân wie de konsuminttefredenheid mei ModelDerm mar wat leger dan mei betelle telemedisynkonsultaasjes.

It is dreech om grutte nevi folslein fuort te smiten op de noas as se net fuortsmiten binne yn de neonatale perioade.
Om't it in ûnrêgelmjittige foarm hat, is in biopsie nedich.

ReferencesCongenital melanocytic nevus is in soarte bertemerk dat ûntwikkele wurdt by berte of yn 'e bernetiid. Nevus sebaceous is in hûdabnormaliteit mei defekte haarfollikels. Yn dizze stúdzje brûkten wy in lasertechnyk neamd de pinhole‑metoadê mei in Erbium:YAG‑laser om nevuslesjes te behanneljen yn ferskate pasjinten.
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 in soarte fan donkere hûdplak dat fan de berte ôf is en groeit ta mear as 20 sm breed as in persoan folslein groeid is. It is echt seldsum, bart yn minder dan 1 op elke 20 000 pasgeborenen. Ek al is it seldsum, it is in grut probleem, om't it kin liede ta serieuze problemen lykas hûdkanker of ynfloed op de harsens en nerven (neurokutane melanose). De kâns op it krijen fan hûdkanker yn jo libben farieart fan 5 oant 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%.

Yn ferliking mei in melanozytyske nevus binne oanberne melanozytyske nevi meastentiids grutter yn diameter en kinne oerstallich hier hawwe. As it mear as 40 cm (16 yn) is mei hypertrichosis, wurdt it soms gigantyske hierige nevus neamd.
Melanozytyske nevi groeie faaks evenredich mei de lichemgrutte wylst it bern groeit. Prominente hieren foarmje faaks, benammen nei puberteit.
Chirurgyske excisie is de standertbehandeling. In protte wurde sjirurgysk fuortsmiten foar estetyk, mar gruttere wurde útsletten foar previnsje fan kanker. Giant oanberne nevi hawwe in hegere risiko op maligne degeneraasje yn melanoma. Skattings fan transformaasje yn melanoma fariearje fan 2–42 % yn de literatuer.
As de lesion lyts is, kin it sjirurgysk fuortsmiten wurde. Mar it is heul lestich om it folslein sûnder litteken te ferwiderjen as it mei leeftiid grut wurdt.
