Composite haemangioendothelioma of the heart as an incidental finding in a woman in her 40s

A previously healthy female patient in her 40s with no relevant medical history presented to her primary care physician with gastrointestinal symptoms. A subsequent CT scan revealed an incidental epicardial/pericardial apical mass. This mass was resected via a minimally invasive anterolateral left thoracotomy. Histological and immunohistochemical analysis revealed a composite haemangioendothelioma. After surgical removal, the patient quickly showed a good general condition and was tumour-free 6 months postresection.
