ReferencesBecker nevus, nazývaný aj Beckerova melanóza, je benígne ochorenie kože. Môže sa objaviť od narodenia alebo sa vyvinúť neskôr a spôsobiť škvrny na koži s vlasmi alebo bez nich. Je to nezvyčajné a väčšinou postihuje mužov. Postihnuté miesto často časom stmavne a môže tam narásť prebytočné ochlpenie. 29‑ročný transrodový pacient prišiel s tmavými škvrnami na koži, ktoré sa objavili vo veku 15 rokov ako malé škvrny. Postupom času sa tieto škvrny rozrástli na väčšie. Vyšetrenie odhalilo tmavé škvrny s vlasmi na pravej strane hrudníka, ramena, chrbta a nadlaktia, s nepravidelnými okrajmi.
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 je bežné kožné ochorenie charakterizované pigmentovou škvrnou s extra rastom ochlpenia na jednej strane tela. Často sa lieči laserom, hoci existujú aj ďalšie možnosti. Používajú sa rôzne typy laserov – buď samostatne, alebo v kombinácii – s vlnovými dĺžkami od 504 do 10 600 nm a reláciami od 1 do 12. Výsledky sa líšia, ale zdá sa, že kombinácia laserov s rôznymi vlnovými dĺžkami prináša lepšie účinky. Vedľajšie účinky sú zvyčajne mierne až stredne závažné začervenanie. Lasery sú vo všeobecnosti bezpečné, avšak poskytujú skôr miernu (nie vynikajúcu) účinnosť pri liečbe Beckerovho nevu.
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.

○ Liečba
Vlasy prekrývajúce névus je možné odstrániť laserom. Vzhľadom na vysokú mieru recidívy je však takmer nemožné odstrániť névy laserom.
