Atrial myxoma

INTRODUCTION

Cardiac myxoma is the most common primary tumor of the heart. Most cases occur in the left atrium during the third to sixth decade of life. Classically, the presentations of cardiac myxomas include obstructive, embolic, and constitutional sym­ptoms and signs. We report a case of atrial myxoma associated with migratory maculopapules, represent­ing an embolic phenomenon without cardiac sym­ptoms and showing the histological findings of intravascular myxomatous material in the dermal vessels, a diagnostic clue to the presence of atrial myxoma.

To our knowledge, there has not been any repo­rted case in the Korean dermatologic literature, to describe left atrial myxoma presenting with migratory erythematous maculopapules. The histologic features of such lesions should alert the clinician to the presence of an otherwise silent atrial myxoma.
