A 1991 report documented the cases of nine patients with both Becker's nevus and malignant melanoma.

Thus the pathophysiology of Becker's nevus remains unclear.

As Becker's nevus is considered a benign lesion, treatment is generally not necessary except for cosmetic purposes.

Of the nine melanomas, five were in the same body area as the Becker's nevus, with only one occurring within the nevus itself.

PN has been linked to Becker's nevus, linear IgA disease, an autoimmune condition, liver disease and T cells.

Becker's nevus (also known as "Becker's melanosis," "Becker's pigmentary hamartoma," "Nevoid melanosis," and "Pigmented hairy epidermal nevus") is a skin disorder predominantly affecting males.

"Epidermal nevus syndrome" is sometimes used as a synonym, but more often as a broader term referring to Schimmelpenning syndrome in addition to nevus comedonicus syndrome, CHILD syndrome, Becker's nevus syndrome, and phakomatosis pigmentokeratotica .

While it is generally considered an acquired rather than congenital disorder, there exists at least one case report documenting what researchers claim is a congenital Becker's nevus with genetic association: a 16-month-old boy with a hyperpigmented lesion on his right shoulder whose father has a similar lesion on his right shoulder.

Pigmented hairy epidermal nevus syndrome is a cutaneous condition characterized by a Becker nevus, ipsilateral hypoplasia of the breast, and skeletal defects such as scoliosis.
