Elastosis perforans serpiginosa (EPS) is a rare disorder showing erythematous or skin-colored hyperkeratotic papules with a serpiginous or arcuate distribution. There are various treatment modalities available, but a standard treatment method has not been established. We report the case of a 33-year-old male patient with a 2-month history of grouped, multiple, annular-shaped, scaly erythematous papules on his right anterior neck. A histopathological analysis revealed increased brightly eosinophilic elastic fibers from the papillary dermis through the epidermis and clutching the dermis at the site of the perforation of the elastic fibers. Immunohistochemical analysis revealed abnormal elastic fibers with transepidermal elimination in the papillary dermis on the elastic stain. Based on these features, the lesion was diagnosed as EPS. After treatment with six sessions of the 585-nm pulsed dye laser over 3 weeks, the lesion was cleared without any adverse events and no recurrence was observed 2 months after therapy.
