Singola metastasi cardiaca da adenocarcinoma intestinale: una rara localizzazione

: Metastasis to the heart from malignancy is a frequent but underestimated event. Tumors that are located in the mediastinum, such as pleural mesothelioma, are more frequently associated with cardiac colonization. Few reports have described metastasis from colon adenocarcinoma, which usually colonizes liver and lungs. Moreover, intracardiac localization is more common for primary cardiac neoplasms than for metastasis. We present an unusual case of a patient operated for colon adenocarcinoma who exhibited a single intracardiac secondary localization. Although the mass was huge, the patient was completely asymptomatic. Strict oncologic follow-up facilitates an early identification of the lesion, which could then be promptly resected.
