Jae Seong Joo*, Jin Ok Baek, Yu Ri Kim, Kyung Moon Lee, Hoon Hur

Frictional Lichenoid Dermatitis (FLD) in children and Dermatitis Papulosa Adultorum (DPA) present with identical clinical features and histopathologic findings, leading to a deceptive resemblance. However, their pathogenesis diverges significantly. Both disorders manifest clinically as asymptomatic multiple skin-colored papules symmetrically appearing on either both elbows or both knees. Histopathologically, they exhibit evidence of interface dermatitis. We report a case of FLD in children and a case of DPA.
