[Cardiac metastasis from a Merkel cell skin carcinoma. A case report]

The authors report the case of a cardiac metastasis of a Market cell skin tumour in a 72 year old woman, presenting with chest pain and infero-lateral myocardial ischaemia simulating an acute coronary syndrome. The diagnosis, suspected on echocardiography, was confirmed by thoracic CT scan. Markel cell carcinoma is a rare skin tumour classified among the malignant neuroendocrine tumours. It has a high metastatic potential, especially to the gastrointestinal tract and the lung. On the other hand, cardiac metastases are quite exceptionally rare.
