Atypical cutaneous and mucosal lichen planus in a 53-year-old Filipino male: case report
Abstract
Lichen planus (LP) is a rare papulosquamous inflammatory disease. We report a 53-year-old male with a 6-month history of multiple, pruritic, brown, atrophic macules on the face. He also had erythematous, pruritic, scaly papules on the trunk, lower back, genitalia and the extensor surface of the upper extremities, as well as plaques with erosions on the lower lip and buccal mucosa. The initial diagnosis of atypical LP was made through dermatoscopy and confirmed through skin punch biopsy and direct immunofluorescence. The patient was successfully treated with topical corticosteroids and chlorhexidine gluconate mouthwash initially, followed by an 8-week course of oral corticosteroids.
