[A case report of primary hemangiopericytoma of the chest wall].

A 35-year-male was found to have an abnormal shadow with an extrapleural sign located in the right lower lung field by a chest X-ray. Chest CT revealed a well demarcated tumor in the chest wall adjacent to the 4th rib. Chest MRI showed that the tumor contained punctate or linear low-intensity areas, which were considered to be small blood vessels. A diagnosis of hemangiopericytoma was established by percutaneous needle biopsy. Under the definite diagnosis, extended resection of the chest wall was performed to remove the tumor with a surgical margin of more than 5 cm, corresponding to surgery for other malignant soft-tissue neoplasmas. Hemangiopericytomas rarely arise in the chest wall, although they can be found in any region which contains pericytes. Preoperative definite diagnoses of hemangiopericytoma have rarely been reported. However, preoperative diagnosis is an important factor in deciding the operative procedure for hemangiopericytoma. It has been reported that hemangiopericytomas show local recurrences and distant metastases, although they are histologically benign. We consider that hemangiopericytomas in the chest wall should be treated with extensive resection corresponding to surgery for other malignant soft-tissue neoplasmas.

[Differential diagnostic problems between nodular fasciitis and soft-tissue sarcomas. A review of the literature and a case report].

After a review of literature and the report of a case with intrathoracic location, the authors consider present criteria for a correct diagnosis of low grade soft tissue sarcoma, when the possibility of nodular fasciitis is under evaluation. Nodular fasciitis is a benign pathology up to day not well characterised from the clinical and pathological point of view. The authors conclude that differential diagnosis between low grade soft tissue sarcoma and nodular fasciitis is frequently possible only on the basis of clinical course evaluation; otherwise the management may be inadequate.

[The surgery of abdominal aortic aneurysms synchronous with neoplastic lesions (apropos of 18 personal observations)].

The management of simultaneously occurring abdominal aortic aneurysm and malignancy is controversial. It is unclear whether to treat the aneurysm first or the malignancy, or both simultaneously. If the malignancy is resected first there is a risk of postoperative rupture of the aneurysm. If simultaneous surgery is performed there is a risk of prosthetic graft infection. This condition leads to many therapeutic problems which, by the light of 18 personal cases occurred in almost ten years and the recent literature, are discussed in this paper.

[A new method of reconstruction for chest wall resection].

Sixteen patients who involved in chest wall disease underwent major chest wall resection between April 1995 and January 1999. The underlying diseases were 6 recurrence of breast cancers, 4 direct invasion by primary lung cancer, 2 metastatic chest wall tumor, one direct invasion by metastatic lung tumor, one direct invasion by metastatic mediastinal tumor, one radio-induced-necrosis of the chest wall, and one chest wall infection. In 9 patients, the thoracic cage reconstruction was performed using double sheets of absorbable mesh (Dexon mesh), cross string sutures and autologous ribs grafts. None of the patients had major respiratory failure and chest wall unstability. No late complications including infections, pains, recurrence and others related to reconstruction materials have been observed.

[Reconstruction of the thoracic wall].

The resection of the thoracic wall for cancer, traumas or results of radiotherapy could require a reconstruction of the same wall with prosthetic material of different nature to the purpose of protect the important intrathoracic structures, avoid the flail chest and maintain a ventilation adjusted with aesthetically acceptable results. Numerous and varied they have been and they are the materials used to such aim, but the more numerous experiences concern the reconstructions of the wall with the employment of nets of Marlex or the patch of Gore-Tex. In the complete two years eight patients have arrived at our observation in which a prosthetic reconstruction has been performed with heterologous material. In three of them has been used the net of Marlex, in five the patch of Gore-Tex of two millimeters of thickness. The prostheses have stayed well you bear and in all the patients the authors have gotten a good stabilization of the thoracic wall.

[Changes in MR imaging appearance of breast cancer after intra-arterial infusion chemotherapy].

The purpose of this study was to evaluate whether the characteristic change in breast cancer related to chemotherapeutic response (CR) and the effect of invasion and toxicity in the skin and pectoralis muscle exist on MR imaging after intra-arterial infusion chemotherapy. A total of 11 patients with histologically proven breast cancer underwent MR study before and after chemotherapy. Changes in images and the dynamic curve-after-chemotherapy were evaluated, including time to maximum signal intensity (SI) and the early phase enhance ratio (EPER) in the tumor. In the tumor, changes in the dynamic curve, time to maximum SI, EPER and necrosis did not correlate with CR, but change in SI on T2-weighted images was suggested to do so. Changes in the dynamic curve and images in the pectoralis muscle and in images on the skin were suggested to correlate with CR. In addition, images changed for the worse in many cases of invasion and toxicity in the pectoralis muscle and in some cases of invasion in the skin. In conclusion, tumors had fewer imaging changes correlating with CR after intra-arterial infusion chemotherapy. Changes for the worse in images of the pectoralis muscle and skin may be useful for the evaluation of invasion.

[The place of surgery in the treatment of advanced localized, recurrent and metastatic breast cancer].

In the multidisciplinary treatment of locally advanced and metastatic breast cancer, aggressive surgical options can be chosen in selected cases. They may allow: survival to be prolonged by the resection of metastases (liver, ovary, lung), symptomatic treatment (bone pain, local recurrence, infiltration of the chest wall), prevention of potentially disabling complications (pathologic fractures, medullary compression), exclusion of another tumoural or non tumoural diseases. The decision to perform surgery has to be discussed between the surgeon and the oncologist so as to optimise its timing. Surgical treatment can follow induction therapy or can precede chemo- or hormonotherapy.

[Patient positioning and its verification: justification, state of the art of the classical practices].

Patient immobilization is considered an important part of the quality control program in radiation therapy. The need for patient immobilization according to the symptoms, ensuring both reproducibility and comfort, is described in the recommendations for level 1 published by the SFPM (Société française de physique médicale) and the SFRO (Société française de radiothérapie oncologique). A customized device, associated with regular controls, is required for level 2. Customized procedures are mandatory in clinical practice for head and neck and brain treatments. Internal margins and movements of patients must be analyzed and controlled as deviations of CTV placement relative to the isocenter of linacs. They could be reduced with efficient positioning devices and accurate customized immobilization systems. Different devices could be used according to tumor locations. Except for subclavicular tumors, their efficacy remains controversial.

[Desmoid tumor of the chest wall infiltrating into the brachial plexus: report of a resected case].

We report a case of a desmoid tumor which developed in the apex of the chest wall. A 18-year-old woman was admitted with left shoulder pain. Chest X-ray showed a mass shadow in the left upper lung field. Chest MRI demonstrated the mass infiltrated into the left brachial plexus. A desmoid tumor was suspected on percutaneous needle biopsy. Resection of the tumor was performed. The mass was 13 x 9 x 5 cm in size and diagnosed pathologically as desmoid tumor. Adjunctive postoperative radiation therapy of 60 Gy was done. Postoperative course was uneventful except motor disturbances of the left fingers. At 15 months postoperatively, there was no evidence of recurrence.

Spinal intradural extramedullary capillary hemangioma: MR imaging findings.

SUMMARY: Spinal intradural extramedullary capillary hemangiomas are extremely rare. We present the MR imaging and histologic findings in three patients with this abnormality. The three patients were men who had symptoms of either myelopathy (n = 2) or radiculopathy (n = 1). The tumors were well demarcated, 1.5-2.0 cm in diameter, and were located at the posterior or posterolateral portion of the thecal sac (one at the L1 level and the other two at the midthoracic level). On MR images, the tumor showed isointensity relative to the spinal cord on T1-weighted images, hyperintensity on T2-weighted images, and strong homogeneous enhancement on contrast-enhanced T1-weighted images in all three patients. In two patients, the dural tail sign was observed. Capillary hemangioma should be included in the differential diagnosis of a spinal intradural extramedullary tumor.

[A case of benign schwannoma arising in the brachial plexus with intrathoracic extension].

A case of benign schwannoma originating from the lowest trunk of the left brachial plexus with intrathoracic extension was reported. Intrathoracic growth of a schwannoma of the brachial plexus has been reported in only five cases in the literature. The patient was a 35-year-old man and had been pointed out an abnormal shadow at the left lung apex on the roentgenogram since 20-year-old. The tumor shadow was increased to seven cm from four in size on recent chest X-ray. We performed a video-assisted thoracoscopic surgery with the oblique skin incision at the left neck and removed the tumor completely and safely.

[A case of schwannoma arising in brachial plexus with intrathoracic extension].

A case of benign schwannoma arising in the brachial plexus with intrathoracic extension was presented. The patient was a 55-year-old man, who was pointed out an abnormal shadow in the left apical region on routine chest X-ray examination. MRI showed that the mass extended to the lowest trunk of the brachial plexus. He had no complaint. Therefore, a diagnostic operation was performed. The tumor was subcapsularly resected with thoracoscopic surgery. Histopathological examination revealed a schwannoma (Antoni type A and B). It should be kept in mind that tumors arising in the brachial plexus are a probable differential diagnosis for tumors at the pulmonary apex, even if no neurological symptoms are seen in the upper extremities.

Ultrasonography: an aid in the diagnosis of masses in pediatric patients.

Ultrasound was used to evaluate 100 pediatric patients suspected of having a mass. This technique was found to be useful in several ways: (1) differentiation of cystic, solid, and complex masses, which is not usually possible with routine roentgenographic evaluation; (2) delineation of free fluid collections from those that are loculated or contained within masses; (3) measurement of the size of both normal and abnormal structures; and (4) confirmation of the abnormal position or absence of organs. Ultrasound was used as a supplement to routine clinical and radiologic studies.
