Keratoelastoidosis marginalis

BACKGROUND: Keratoelastoidosis marginalis is a rare disease that is a variant of solar elastosis. Long-term ultraviolet radiation exposure and chronic trauma secondary to manual labor are considered to be inciting factors.

OBJECTIVE: To outline the clinical and histological features of this disorder.

METHODS: We report two cases and review the literature.

RESULTS: Both patients had persistence of their disease despite multiple topical treatment regimens.

CONCLUSION: Keratoelastoidosis marginalis is a chronic and progressive disease that is difficult to treat. The differential includes focal acral hyperkeratosis and acrokeratoelastoidosis.
