Abstract

We present the case involving a 59-year-old male patient with a history of hypertension and dyslipidemia, who consulted for a dermatosis of 6 months' duration. Physical examination revealed erythematous-violaceous annular plaques in the axillae, back, and lower limbs, mostly asymptomatic. The presumptive diagnosis was annular lichen planus, confirmed by histopathological study. Treatment with topical and oral corticosteroids resulted in the complete resolution of the lesions within one month. This case highlights an atypical variant of lichen planus, emphasizing the importance of differential diagnosis and suggesting the need to investigate its relationship with comorbidities such as hypertension and dyslipidemia, among others.
