Abstract

Background Becker's nevus (BN) presents as a hairy patch or plaque with or without

The Treatment of Becker’s Nevus by Combination Therapy: Dr. Hoon Hur’s Golden Parameter Therapy and Dr. HOON Hur’s Optimal Melanocytic Suicide-1 Parameter Therapy

“…It might appear in males at puberty because of gene defect and circulating androgens [8]. Becker's nevus can be easily diagnosed clinically but sometimes a biopsy may be required in order to differentiate the lesions from congenital melanocytic nevus and congenital smooth muscle hamartoma [3,4]. In order to distinguish it from congenital melanocytic nevus and congenital smooth muscle hamartoma, it is very essential to figure out whether the lesion was present at birth or developed subsequently.…”

“…Moreover, in most cases, pseudo-Darier's sign with temporary induration after rubbing the lesion is observed. Histologically, congenital smooth muscle hamartoma is characterized by the hyperplasia of smooth muscle bundles throughout the dermis [3,4]. The histopathological findings of Becker's nevus represents that moderate elongation and focal fusion of rete ridges with increased number of melanocytes and enhanced melanin deposition in the epidermis, and increased number of arrector pili muscles and the hyperplasia of smooth muscles in the dermis.…”

“…A total of forty-two Korean patients (age range: 7-38 years old, mean age: 16.3 years old) with no significant medical or familial history who were clinically diagnosed with Becker's nevus (Figures 1,4,6,8) were participated in this study. Written consents were received from all of the patients before undergoing this laser treatment.…”

“…Becker's nevus, a benign cutaneous pigmentary hamartoma with a localized hypertrichosis, may occur on the shoulder or upper trunk, occasionally elsewhere on the body during childhood or adolescence [1][2][3]. The histopathologic findings demonstrate that there is no nevus cell in the basal layer of epidermis and in the dermis and Becker's nevus does not develop into malignant lesion [3,4]. Treatment for Becker's nevus may not be necessary except for cosmetic purposes.…”

The efficacy of intense pulsed light for Becker's nevus: A retrospective analysis of 45 cases

“…Its prevalence can be as high as 2%‐4% in young males in some regions 1,2 . It can occur in both males and females either at birth or at adulthood 3‐5 . Some patients may have a family history 6‐8 .…”
