While it can arise at any age, it most frequently affects adults between the fourth and sixth decades of life, with a higher prevalence reported in men

The condition is categorized as primary (idiopathic) or secondary to underlying causes such as fecal contamination, local trauma from overzealous hygiene, anorectal pathology (including hemorrhoids and anal fissures), infectious organisms, or dermatoses like contact dermatitis and psoriasis

The condition is categorized as primary (idiopathic) or secondary to underlying causes such as fecal contamination, local trauma from overzealous hygiene, anorectal pathology (including hemorrhoids and anal fissures), infectious organisms, or dermatoses like contact dermatitis and psoriasis

Pathophysiologically, disruption of the perianal epidermal barrier, exposure to irritants, and mechanical excoriation precipitate a persistent itch-scratch cycle that manifests clinically as erythema, maceration, lichenification, and secondary skin breakdown
