[Atrial myxoma: cutaneous manifestations].
BACKGROUND
Atrial myxomas may have variable misleading symptoms, explaining frequent delays in diagnosis. Multiple embolisms with irreversible consequences may occur. The dermatologist has a prominent role to play, as the clinical picture includes cutaneous signs.


METHODS
A 60 year old woman, with previous history of joint pain and Raynaud's phenomenon suffered a sudden neurological transitory ischemic event. The cutaneous manifestations associated left forearm erythematous macules, distal ischemia of the left fourth and fifth fingers and livedo of both lower limbs. Cardiac echography confirmed the clinical diagnosis of atrial myxoma. Surgical excision was followed by rapid and complete cure.


CONCLUSIONS
Atrial myxoma is a rare benign tumor usually revealed by prominent cardiac and embolic manifestations. Systemic and cutaneous signs may however be the sole symptoms, warranting the dermatologist's attention.
