Author and Disclosure Information
Hair pigmentation is a complex phenomenon that involves many hormones, neurotransmitters, cytokines, growth factors, eicosanoids, cyclic nucleotides, nutrients, and a physicochemical milieu. We report a case of repigmentation of gray hairs in lesions of annular elastolytic giant cell granuloma (AEGCG) on the scalp of a 67-year-old man.
Practice Points
- Hair repigmentation can be a clinical clue to a subjacent inflammatory disease.
- Hair depigmentation associated with aging may be a reversible condition under proper stimulation.
