Clinicopathological studies of primary malignant chest wall tumor on 16 cases operated between 1962 and 1988 were made. Of 9 osteogenic sarcomas, 8 cases were chondrosarcoma and 1 case was Ewing's sarcoma. Of 7 soft part sarcomas, 2 cases were fibrosarcoma, liposarcoma and neurogenic sarcoma respectively, and one case was hemangiosarcoma. Most of the cases had symptoms, such as chest mass and/or chest pain comprehend symptoms for more than one year. The intrathoracic growth of tumor is common, especially in osteogenic sarcoma. The maximum size of tumor was 8.2 cm in a mean diameter. Preoperative histological diagnosis is difficult to make even though various radiologic diagnosis or pathological technique as biopsy or cytology were assessed. And true rate of preoperative diagnosis is limited only 43.8%. Wide resection combined with the tissue distant more than 3 cm length from tumor is recommended and 6 cases underwent combined resection of diaphragm, pericardium or lung. 3 cases underwent chest wall reconstruction using the Marlex mesh and 10 cases were able to direct closure, in 13 cases with ribs resection. The 5 year survival rate of endurable cases was 62.2%, and that of soft tissue sarcoma (68.6%) is better than that of osteogenic sarcoma (41.7%). The recurrent or metastatic rate in high, 7 cases (43.8%), but reoperation was added for 5 cases of local recurrence or for a case of lung metastasis. 5 year survival rate of cases with recurrence or metastases is relatively good, 46.8%, especially excellent in 4 cases with recurred lesions after more than 2 years of tumor free interval.

A 54-year-old black man presented with a soft-tissue sarcoma of the left anterior thigh. Surgical staging studies and initial biopsy results identified the lesion as a grade IIB pleomorphic liposarcoma. After radical hip disarticulation, follow up pathologic studies of the disarticulated limb showed the tumor to be confined to the anterior compartment of the left thigh without extracompartmental extension. The post-excisional surgical pathology report identified at least four different malignant mesenchymal elements: liposarcoma, myosarcoma, chondrosarcoma, and extraosseous osteogenic sarcoma. The sarcoma was therefore reclassified as a malignant mesenchymoma. The fact that the tumor was found to be intracompartmental at the time of surgery changed the staging of the tumor to stage IIA. A radical surgical margin, as recommended by Enneking, remained the treatment of choice. Three months postoperatively, the patient had chest pain and dyspnea. Chest films revealed multiple pulmonary nodules and the patient died of pneumonia 3 months later.

The immunoconjugate XMMCO-791/RTA consists of ricin A chain bound to a murine monoclonal antibody MoAb 791T. This monoclonal antibody (MoAb) binds to a glycoprotein of 72 kD, which is expressed on human colorectal carcinoma, ovarian carcinoma, and osteogenic sarcoma. XMMCO-791/RTA was tested in a Phase I trial with proposed dose escalation steps of 0.02, 0.04, 0.15, and 0.2 mg/kg per day. Twelve patients with metastatic colorectal carcinoma were treated at 0.02, 0.03, and 0.04 mg/kg per day dose levels administered over 1 hour on days 1-5. Study-related toxicities were hypotension (6 patients); greater than 10% weight gain (6 patients); peripheral edema (9 patients); fever (4 patients); confusion (3 patients); diarrhea (3 patients); proteinuria, as identified by dipstick (3 patients), greater than 0.6 mg/dl decrease in serum albumin (11 patients); greater than 25% decrease in oncotic pressure (10 patients), and a decrease in ionized calcium (8 patients). Six patients received a second course of treatment. HAMA levels developed in 9 patients and titers increased with number of courses administered. Decreased overall toxicity, in comparison to the first course, was noted, but one patient had an allergic-type response (hypotension, crushing chest pain, diaphoresis) after the test dose of the second course (HAMA level > 10,000 IgG). Life-threatening toxicity in the form of fluid shift, resulting in noncardiac pulmonary edema and third-spacing occurred after course 1 in 1 of 3 patients at the 0.04 mg/kg per day level. No further dose escalation was attempted and no antitumor activity was seen.

A 48-year-old man with neurofibromatosis type 1 presented with chest pain, paroxysmal hypertension, tachycardia, and progressive respiratory insufficiency. Clinical investigation displayed calcified tumors in the anterior mediastinum and pararenal region. Histological examination at autopsy revealed composite tumors consisting of pheochromocytoma and malignant peripheral nerve sheath tumor (MPNST) at two sites: the left adrenal gland and the region surrounding the inferior vena cava, probably corresponding to the right adrenal gland. The MPNST component showed a varied histological appearance, including hyalinized bands with polygonal cells, a cartilaginous and myxoid stroma, a hemangiopericytomatous architecture, and a fibrosarcomatous structure, which suggested osteosarcoma, chondrosarcoma, angiosarcoma, and fibrosarcoma, respectively. In addition, based on the ultrastructural findings, the gastrointestinal tract was involved with mesenchymal tumors showing neurogenic differentiation. These lesions suggest the divergent cellular differentiation of neural crest-derived cells to mesenchymal elements as well as neuroectodermal neoplasms.

A 13-year-old girl presented with dyspnea and chest pain. Chest radiography showed a massive left pleural effusion. Computed tomography revealed a tumor of the fourth rib. A large bloody effusion was drained. Her anemia worsened (hemoglobin: 4.8 g/dl), and hemorrhagic shock ensued. An emergency thoracotomy was performed. Bleeding from the ruptured tumor was identified. The fourth rib, the tumor, and the adjacent tissues were resected. Histopathologic examination revealed a ruptured primary osteosarcoma of the rib with pleural dissemination.

A 40-year-old woman presented with a known case of osteogenic sarcoma of the right leg and underwent below-the-knee amputation. The preoperative workup was negative for distant metastases, and the patient was followed regularly. Two years later she developed dyspnea and chest pain. Computed tomography revealed diffuse left lung metastases with pleural involvement and nodular metastases in the right lung. Tc-99m methylene diphosphonate whole-body bone scanning revealed the amputated right leg with a clean stump but with widespread metastases in the right thigh involving soft tissue and bone, and the pelvis, left femur, and skull. In addition, diffuse left lung metastases involving both parietal pleura and lung parenchyma were seen. Tc-99m methylene diphosphonate uptake has been observed in the soft tissue and lungs in patients with osteogenic sarcoma but is rarely observed in practice with this degree of aggressiveness.

A 36-year-old woman was hospitalized for preoperative chemotherapy for osteosarcoma. She received intravenous fluids for 12 hours for volume expansion, then methotrexate 24 g (12 g/m2) over 6 hours. This was followed by intravenous leucovorin 200 mg over 1 hour. Two hours after the methotrexate infusion the patient developed chest pain and bradycardia. An electrocardiogram revealed sinus pauses, and telemetry recordings indicated a 4-beat run of ventricular tachycardia. A cardiac work-up consisting of cardiac enzyme level determination, two-dimensional echocardiography, and an adenosine technetium-99m tetrofosmin stress test was negative for structural and ischemic heart disease. The patient recovered without treatment and, approximately 2 weeks later, received a second course of methotrexate at half the dose without complication. One month later the patient received treatment with doxorubicin and cisplatin; 2 days later she died unexpectedly at home. Clinicians should be aware that high-dose methotrexate can cause cardiac symptoms and arrhythmias in previously healthy adults. This complication warrants attention and needs additional clinical investigation.

We examined 14 spindle cell tumours of the pleura that were sent to a Mesothelioma Panel for re-evaluation after a primary suspicion of mesothelioma. The clinical, histological, immunohistochemical and CGH findings were investigated. Final diagnoses were eight sarcomatoid mesotheliomas (SM) and six non-mesotheliomas: two pulmonary sarcomatoid carcinomas, an epithelioid hemangioendothelioma, a malignant solitary fibrous tumour, a malignant pleural smooth muscle tumour and an extraskeletal osteosarcoma. Seven of the eight SM and two of the other six tumours presented with unilateral pleural effusion, dyspnoea, and chest pain, which are characteristic clinical findings in malignant mesothelioma. No single antibody used in the immunohistochemistry separated SM from other tumour types. The most frequently observed chromosomal losses in SM were 4q, 4p11-p13/p15, 6q and 13. Losses of 4p11-p13/p15 and 4q occurred in combination in four out of five SM with detectable chromosomal changes, but neither was found in any of the other tumours. Gain or high-level amplification of 5p was also common in SM. According to our results and literature, losses at 4p, 4q and 9p and gain at 5p are the chromosomal changes that best differentiate SM from pleural sarcomas and lung carcinomas. CGH analysis may help distinguish a cytokeratin-positive SM from a sarcomatoid carcinoma. Similarly, in the case of a cytokeratin-negative tumour, CGH analysis may disclose chromosomal changes characteristic of sarcomas or mesotheliomas.

Limb-salvage surgery for malignant tumors frequently involves reconstruction with an endoprosthesis anchored to bone by using third-generation cementing techniques. A 10-year-old boy with osteosarcoma had a pulmonary embolus caused by polymethylmethacrylate after having limb-salvage surgery that used high-pressure cementing techniques. He experienced transient postoperative chest pain, and a new wedge-shaped radiodense pulmonary lesion appeared on a computed tomography scan of the chest. A thoracotomy for resection of suspected metastatic osteosarcoma revealed a pulmonary infarct caused by cement embolization. Awareness of this potential complication should prompt investigation of possible pulmonary embolism and may prevent unnecessary thoracotomy.

Carcinosarcoma of the lung is a malignant tumor composed of a mixture of carcinoma and sarcoma elements. The carcinomatous component is most commonly squamous followed by adenocarcinoma. The sarcomatous component commonly comprises the bulk of the tumor and shows poorly differentiated spindle cell features. Foci of differentiated sarcomatous elements such as chondrosarcoma and osteosarcoma may be seen. Aspergillus pneumonia is the most common form of invasive aspergillosis and occurs mainly in patients with malignancy, immunocompromising or debilitating diseases. Patients with Aspergillus pneumonia present with fever, cough, chest pain and occasionally hemoptysis. Tissue examination is the most reliable method for diagnosis, and mortality rate is high.We describe a case of primary carcinosarcoma of the lung concurrently occurring with invasive pulmonary aspergillosis in a 66-year old patient.
