Description
Ameije Anthony and colleagues published a 2026 case report of a Becker nevus, a pigmented skin patch with increased hair growth, appearing in the beard area of a 25-year-old man. The darkened plaque with thicker terminal hair covered the left side of his face and neck, yet he had no muscle or skeletal abnormalities. A biopsy was taken to confirm what the lesion was, and the report is framed as a teaching case.
Microscopy showed thickened skin with broadened ridges, extra pigment in the basal layer, bundles of smooth muscle, and enlarged hair follicles. The feature best supporting the accepted explanation is the combination of extra hair and onset at puberty, when rising androgens can activate the overactive androgen receptors thought to drive this condition. The case reminds clinicians that a beard-distribution patch in a young man may be a Becker nevus rather than a shaving-related problem.
