Özet:

Lichen striatus is a well-known, acquired, self-healing, linear inflammatory dermatosis. Its etiology remains unclear. It rarely affects adults, and it is characterized by abrupt onset of coalescent papules, in a linear disposition, usually on the extremities. It is usually localized and asymptomatic; however, when the onset occurs in adulthood, patients may experience widespread lesions and pruritus. The lesions are located on extremities and less commonly on the trunk, and they follow the developmental lines of Blaschko. Histopathology findings indicate both lichenoid and spongiotic dermatitis. The therapeutic approach usually used is topical steroids. It is reported here the case of an adult woman with erythematous violaceous papules on the left leg, diagnosed with lichen striatus by clinical and histopathological correlation.
