Becker nevus
☆ I Stiftung Warentest-resultaten 2022 från Tyskland var konsumentnöjdheten med ModelDerm bara något lägre än med betalda telemedicinkonsultationer.
Den kännetecknas av en stor nevus med riklig hårväxt över området.

Becker nevus , även kallad Becker melanos, är en godartad hudsjukdom. Det kan dyka upp från födseln eller utvecklas senare, vilket orsakar fläckar på huden med eller utan hår. Det är ovanligt och drabbar främst män. Det drabbade området mörknar ofta med tiden, och överflödigt hår kan växa där. En 29-årig transpatient kom in med mörka fläckar på huden som började vid 15 års ålder som små fläckar. Med tiden växte dessa fläckar till större fläckar. Undersökningen visade mörka fläckar med hår på höger sida av bröstet, axeln, ryggen och överarmen, med oregelbundna kanter.
Becker's nevus is also known as Becker melanosis. It is a benign lesion which can be presented as congenital or acquired with hairless or hypertrichotic lesions. It's a rare case which affects mainly male individuals. It is often pigmented and gets darker by time and excessive hair growth can be seen over it. A 29-year-old transgender patient presented with hyperpigmentation with the lesion which started at the age of 15 as a small hyperpigmented macule. The lesion increased gradually to form giant patches. On examination a right-side hyperpigmentation involving the anterior chest, shoulder, scapular region, upper arm with hypertrichosis and irregular margins.

Becker's nevus är en vanlig hudsjukdom som kännetecknas av en pigmenterad fläck med extra hårväxt på ena sidan av kroppen. Det behandlas ofta med laser, även om det finns andra alternativ. Olika typer av lasrar har använts, antingen ensamma eller tillsammans, med våglängder från 504 till 10 600 nm och sessioner från 1 till 12. Resultaten varierar, men att kombinera lasrar med olika våglängder verkar fungera bättre. Biverkningar är vanligtvis mild till måttlig rodnad. Medan lasrar i allmänhet är säkra, ger de måttlig effektivitet (inte utmärkt) för Beckers nevus.
Becker's nevus is a common pigmented dermatosis, usually featured by ipsilateral pigmented patch with hypertrichosis. Becker's nevus is often treated with various types of lasers although other regimens are available. A variety of lasers had been used alone or in combination to treat Becker's nevus. Laser wavelengths used for Becker's nevus ranged from 504 to 10,600 nm, while the number of treatment varied from 1 to 12 sessions. The clinical outcomes were mixed although combination of lasers with different wavelengths appeared to achieve a better efficacy. Adverse effects were usually mild to moderate erythema. While lasers are relatively safe, their efficacy for Becker's nevus is moderate.

○ Behandling
Håret som ligger över nevus kan tas bort med laser. Men på grund av den höga återfallsfrekvensen är det nästan omöjligt att ta bort nevi med laser.
