Clinically, it presents with erythematous or hypopigmented patches covered by characteristic greasy, white-to-yellow scales that can be associated with variable pruritus

Clinically, it presents with erythematous or hypopigmented patches covered by characteristic greasy, white-to-yellow scales that can be associated with variable pruritus The underlying pathophysiology involves an inflammatory response to the proliferation of commensal *Malassezia* yeast species, altered skin surface lipid composition, epidermal barrier disruption, and host immune susceptibility
