Becker Nevus Syndrome

  • We believe that the lipofilling technique is a natural and valuable treatment option for thoracic anomalies in Becker nevus syndrome with a major impact on patient's quality of life.[ncbi.nlm.nih.gov]
  • You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.[rarediseases.info.nih.gov]


  • (Outcomes/Resolutions) The prognosis of Becker’s Nevus is excellent on its complete excision and removal Since, these are benign conditions, the prognosis is generally excellent even if no treatment is provided and only periodic observation maintained[dovemed.com]
  • Prognosis The naevus remains indefinitely. [ 2 ] Becker naevus syndrome [ 1, 6, 7 ] This is a Becker's naevus with additional abnormalities of underlying tissues derived from ectoderm. It is a type of epidermal naevus syndrome.[patient.info]
  • Prognosis Prognosis is determined mainly by cardiac complications. Most patients with LEOPARD syndrome lead a normal life.[emedicine.medscape.com]


  • Etiology The etiology of Becker’s nevus remains unclear. It is a hamartoma of ectodermal and mesodermal derivatives that is thought to be hormonally responsive given the augmented smooth muscle and peripubertal growth.[dermatologyadvisor.com]
  • The exact etiology is unknown, but androgen stimulation may be responsible for the hypertrichosis and darker pigmentation in postpubertal males [5] .[ijsronline.net]
  • The male predominance, onset at or after puberty and the hypertricosis suggest that local androgen hypersensitivity may be an etiological factor.[drsandeshgupta.com]
  • Pathophysiology The pathogenesis and etiology of Becker nevus remain uncertain.[emedicine.com]


  • In addition, a significant increase in the number of androgen receptors in Becker melanosis lesional skin has been reported. [2] Epidemiology Frequency A study of 19,302 men aged 17-26 years revealed a prevalence of Becker melanosis of 0.52%.[emedicine.com]
  • Epidemiology It is more common in men. One study reported a prevalence of 0.52% in men aged 17-26 years. [ 4 ] Presentation [ 1, 2 ] A large brown area, sometimes covering half the upper back or chest. Most lesions become hairy (hypertrichosis).[patient.info]

  • Pathophysiology The pathogenesis and etiology of Becker nevus remain uncertain.[emedicine.com]
  • Pathophysiology Thedevelopmental anomalies associated with Becker’s nevus syndrome,including breast hypoplasia, supernumerary nipples and musculoskeletalanomalies, are similar to the spectrum seen in the epidermal nevussyndrome and suggest mosaicism.[dermatologyadvisor.com]


  • Current medical research has not established a way of preventing the occurrence of Becker’s Nevus However, if the signs and symptoms of melanoma (such as a suspicious-looking pigmented spot that changes in color and shape) are observed, then immediate[dovemed.com]
