A case of angiosarcoma of the breast in a 55-year-old woman is reported. It is clear that no effective treatment has so far been devised. The time from treatment to death was 41 months in this patient, compared with 25 months in collected cases from the literature. The possible value of adjuvant chemotherapy is stressed.
A 10-year-old, lethargic, potbellied pig presented with signs of abdominal discomfort and a palpable abdominal mass. Laparotomy revealed a 20 cm diameter mass on the spleen and smaller masses on the omentum and liver. After euthanasia and histologic examination of the hepatic mass, the diagnosis was hepatocellular carcinoma.
Authors present a case of epithelioid haemangiosarcoma of the thyroid gland in a 54-year-old female with a history of eufunctional nodular goitre. The patient was treated by total thyroidectomy with extirpation of cervical lymph nodes and by subsequent chemotherapy. The tumour behaved highly aggressively with early generalization and unusual way of metastatic spread into the wall of the stomach and duodenum. The patient died 3 months after the surgery due to therapeutically unmanageable bleeding into the GIT. The clinico-pathological aspects of the case are discussed.

The case of a young 32 year old male with a primary cardiac angiosarcoma is reported. The neoplasm manifested itself by a quickly increasing cardiac tamponade but without metastases. The nonradical resection of the tumor was made because of local invasion with tumor tissue. The patient was followed-up for 3 years after the surgery and no recurrence of the malignant process was observed. Cardiac angiosarcoma is a very rare malignant tumor of soft tissues. In spite of significant progress in clinical treatment, for a patient diagnosed antemortem with cardiac angiosarcoma, the long-term expectations are usually very poor. Commonly known risk factors for this group of neoplasms (haemangioma of skin, chroniclymphedema, chronic post-tuberculosis pleurisy, X-ray, thorium dioxide) cannot be easily associated with the primary cardiac angiosarcoma cases. The search for chromosomal anomalies and gene mutations leading to cardiac angiosarcoma is ongoing. There is hope that recently obtained evidence for mutation of the p53gen, will provide a better understanding of this heart neoplasia.
