Primary monophasic mediastinal, cardiac and pericardial synovial sarcoma: a young man in distress

A 19-year-old male was admitted because of exertional. dyspnoea. The imaging studies revealed epicardial, pericardial. and mediastinal masses. The tumours could not be resected through a minor thoracotomy, only biopsies could be taken. Analyses led to the final diagnosis of a monophasic synovial sarcoma. The patient preferred a conservative and palliative approach. Three months later he died at home. Autopsy demonstrated dramatic extension of the tumour masses. We conclude this report with a discussion on primary cardiac tumours.
