Abstract

Lichen striatus is a rare inflammatory dermatosis that
influences mostly children, being rare reports in adults. The pathogenesis is
unknown. In addition, lichen striatus is demonstrated as T-cell mediated
inflammatory cutaneous disease. It is characterized by linear tendency, usually
on the extremities. Its most typical property is the linear arrangement of
slightly raised, lichenoid papules. A 28-year-old woman presented with a
3-month history of an asymptomatic linear erythematous violaceous papular
lesions on her left abdominal area. Skin biopsy was performed in terms of
differential diagnosis from other linear distributions of inflammatory
dermatoses. Histopathological examination revealed hyperkeratosis, acanthosis,
focal parakeratosis, exocytosis, subbasal dissociation of an area, vacuolar
degeneration of the basal membrane, perivascular and lichenoid lymphocytic
infiltration. As a result, our case was diagnosed as lichen striatus,
clinically and histologically. Topical pimecrolimus ointment twice a day
therapy was preferred in the patient.
