One patient with a large inoperable malignant hemangiopericytoma and three patients with local recurrence and/or metastases were treated with combination adriamycin, 50 mg/m2, and DTIC, 600-700 mg/m2, intravenously every 4 weeks. Two achieved palliation, one with measureable shrinkage of tumor, and the other with loss of incapacitating lower limb edema secondary to vascular and lymphatic obstruction. The third patient objectively had a less than partial response. The fourth patient did not respond to adriamycin and DTIC or to a subsequent trial of cis-platinum, 60 mg/m2, intravenously every 3 weeks. However, radiotherapy produced an objective response at the site of the local recurrence and relief of painful bone metastases. Two patients died of progressive disease; the third patient has stable disease and is continuing chemotherapy; and the fourth patient died, probably from adriamycin-induced cardiac failure in the presence of rapidly advancing intraabdominal metastases. The combination of adriamycin and DTIC is active in malignant hemangiopericytoma, and palliation of advanced disease can be achieved. However, prolonged survival is uncommon in the presence of a large tumor burden.

An echocardiogram demonstrated a large tumor in the left atrium of a 47-year-old woman with sudden heart failure. Emergent cardiotomy showed that the tumor arose from the left atrial wall, and almost entirely occupied the left atrium. Grossly, the tumor had partly undergone necrosis. Histologically, the tumor consisted predominantly of round to polygonal cells with ill-defined cell borders surrounding 'stag horn'-shaped blood vessels. Mitosis was frequently seen with abnormal mitotic figures. Immunohistochemically, the tumor cells diffusely expressed vimentin and focally expressed factor XIIIa and human leukocyte antigen-DR. A few tumor cells expressed S-100 protein or alpha-smooth muscle actin. Histopathological diagnosis was malignant hemangiopericytoma of the left atrium. Most tumor cells expressed matrix metalloproteinase (MMP)-2 and MMP-3, and several cells expressed MMP-9, all of which are capable of degrading a major component of basement membrane (i.e. type IV collagen). Furthermore, tumor cells expressed membrane type 1 MMP and tissue inhibitor of metalloproteinase-2, both of which are required for activation of proMMP-2. Fourteen months after the surgical removal, she died of systemic recurrent tumors.

We describe the patient with gigantic chest tumor admitted to the hospital because of dyspnoea. The patient was operated on after the elimination of suspicion of acute pulmonary embolism. Cardiovascular failure was caused by the huge arterial-venous fistula in the tumor and diastolic heart failure were the reasons for dyspnoea. On the basis of the microscopic examination hemangiopericytoma (HPC) was diagnosed--a mesenchymal tumor derived from pericytes. We present in our paper the rules applying to dealing with HPC.

Cardiac hemangiopericytoma is a rare soft tissue tumor. We describe a case of hemangiopericytoma in the left atrium, which was diagnosed as myxoma preoperatively. A 70-year-old woman was admitted with heart failure. An echocardiogram showed a large myxoma-like mass in the left atrium, herniating into the left ventricle; therefore, an emergency operation was performed. Histological examination revealed a malignant hemangiopericytoma. The patient's postoperative course was uneventful, but she died due to a local recurrence 4 months after the operation.

We describe the case of a 91 years old woman admitted to our department for dyspnea associated with drowsiness. At the admission to the Emergency Room the patient stay in a comatose state and blood tests performed showing severe hypoglycemia (38 mg/dl at admission in non diabetic patient). Anamnestic history: multifactorial anemia; frequent hospitalizations for heart failure; AMI treated with stenting; in 1986 Haemangiopericytoma resection in the right iliac region; in 2006 palliative surgery for recurrence with residual mass. Blood tests showed lower levels of insulin and normal C- peptide serum concentration in correspondence of low glucose concentration (in relation to continuous and adequate parenteral nutrition), IGF 1 and GH level was respectively suppressed (IGF1=47 ng/ml whit normal range 97-331 ng/ml) and normal/low (GH 0.43 uUI/mL whit normal range 0.06-14.00 uUI/mL).Therefore hypoglycemia appeared related to paraneoplastic production of IGF -2.
