A clinical case of metastatic osteosarcoma in the heart cavity

Tumors of the heart are catalogued as a poorly studied area of clinical oncology because of an extreme rarity of this pathology, absence of pathognomonic symptoms, a large variety of clinical manifestations, and diagnostic complexity. In order to achieve diagnostic and therapeutic adequacy, clinicians need to be aware of cancer heart diseases and their frequently atypical clinical manifestations. The report presents a clinical case of tumor spreading through the vascular system and malignant lesions of the right atrium of the heart in a patient with osteosarcoma of the humerus, where osteosarcoma metastases are resected and plasty of the right atrium is performed by using a pericardial patch.
