Annular lichenoid dermatitis of youth is a rare chronic dermatosis with an unknown cause, affecting both genders at an equal frequency. It is clinically characterized by a hypopigmented center and an erythematous border or hyperpigmented annular patches or plaques. The differential diagnosis includes annular dermatoses, such as tinea, erythema annulare centrifugum, erythema chronicum migrans, morphea, and mycosis fungoides. In this case report, we examined the clinical and histopathological features of two male patients aged 9 and 12 years with annular lichenoid dermatitis and presented their 3-year follow-up data while also reviewing the cases reported in the literature.
