Extensive pulmonary metastases in young boy with primary cardiac angiosarcoma: a case report.

Primary cardiac angiosarcoma is rare and even more so in patients as young as the case described. The diagnostic process poses several challenges to the clinician, of which the obtaining of a histological sample is one. This case report demonstrates aspects both unique and typical of this rare disease. It also describes an effective option for obtaining tissue for a histological diagnosis in patients whose clinical condition may not allow biopsy under general anaesthesia.
