☆ U rezultatima Stiftung Warentest-a za 2022. iz Njemačke, zadovoljstvo potrošača ModelDerm-om bilo je samo nešto niže nego s plaćenim telemedicinskim konsultacijama.
Uočeno je neuobičajeno više linija. Melanonihija (Melanonychia) je uglavnom dobroćudan, ali ako na ovom nivou ima mnogo nepravilnih linija, može se razmotriti biopsija.

Mnogi pacijenti zabrinjavaju melanonihiju, jer uzrokuje smeđe-crnu promjenu boje nokatne ploče. To je čest razlog za promjenu boje noktiju, a uzroci variraju od benignih do potencijalno ozbiljnih, poput melanoma. Uzdužna trakasta melanonihija može proizaći iz različitih lokalnih ili sistemskih faktora.
Melanonychia is a very worrisome entity for most patients. It is characterized by brownish black discoloration of nail plate and is a common cause of nail plate pigmentation. The aetiology of melanonychia ranges from more common benign causes to less common invasive and in situ melanomas. Melanonychia especially in a longitudinal band form can be due to both local and systemic causes.

Melanonychia represents a brown to black discoloration of the nail plate that may be induced by benign or malignant causes. Two main mechanisms are involved in the appearance of melanonychias, i.e., melanocytic activation and melanocytic hyperplasia.
Široka, duboko pigmentirana traka s nepravilnim linijama i pigmentiranim proširenjem na periungualna tkiva znak je melanoma.
