Lasers effective treatment for Becker's Nevus
Becker's nevus, named after American dermatologist Sam Becker, not the co-founder of Steely Dan Walter Becker, is a pigmented nevus ( mole) which darkens and develops hair, usually with the onset of adolescence. It is unusual to develop a Becker's nevus on the face as most such lesions occur on the shoulder, scapula ( shoulder blade) or upper chest. Like you, most patients are male (5:1) and it is felt that androgens cause these growths to become more prominent. Interestingly, acne often develops in this unsightly patch.
Although there are reports that melanoma can develop in a Becker's nevus, their treatment is generally considered cosmetic. Lasers have dramatically improved the success rate and appearance of such treatment which was once limited to surgery. While the Q switched ruby laser was originally used, Velez et al ( British Journal of Dermatology, Feb. 2005) showed that the erbium: Yag laser is superior. The long pulsed Alexandrite laser has also been successfully utilized ( Derm. Surg, July 2009). I am less familiar with the use of IPL for treating these lesions, but the pain should be minimal if a cooling device is used in conjunction with the treatment. This also should prevent burning or other side effects from the treatment.
The pigmentation in a Becker's nevus is lodged in the keratinocytes rather than the dermis so, it should respond to IPL treatment . Nonetheless, it seems to me that a laser would be preferable.
Incidentally, the American actor Richard Gere sports a Becker's nevus on his left upper back. This interesting lesion can be seen in American Gigolo or an Officer and a Gentleman.
