A Case of Keratoelastoidosis Marginalis / 대한피부과학회지

ABSTRACT

Keratoelastoidosis marginalis is a rare skin disorder. Clinically it consists of small, firm, linear hyperkeratotic papules, characteristically along the margin of the hands. Histopathologically it shows hyperkeratosis, acanthosis, solar elastosis, and degeneration of collagen and elastic fibers. Long-term ultraviolet radiation exposure and chronic trauma are considered to be precipitating factors. Herein, we report a case of keratoelastoidosis marginalis and a review of the related literature.
