  • Hemangiopericytoma is uncommon vascular neoplasm that arises from pericytes arround the capillary walls. It was first described as a distinct vascular neoplasm by Stout and Murray in 1942 The anatomic distribution is widespread throughout the body, with approximately one third occur in the head and neck. No sex predilection has been found. Although middle age appears to be the most prevalent time of onset, this neoplasm has been found in all age groups. The differentiation between benign and malignant hemangiopericytoma can be difficult. Although the majority of these tumors are benign, there are malignant variants that can metastasize. Metastasis of seemingly benign tumors may appear year of decade later, so long term close follow-up is needed. The treatment of choice is complete surgical excision of the tumor. Despite their vascular origin, these tumors are relatively radioresistant. Radiation therapy is reserved for inoperable metastases or treatment of postoperative surgical fields. Here we present a case of hemangiopericytoma occuring on the Lt. buccal mucosa.

  • Chondrosarcoma of the chest wall is a rare primary neoplasm found to occur in elderly men. Patients present with an enlarging, painful, anterior chest wall mass arising from either the vicinity of the costochondral junction or the sternum. Treatment includes wide resection with appropriate chest wall reconstruction. We report an unusual presentation of this uncommon tumor occurring as a huge chest wall mass in a young teenage girl.

  • Vascular anomalies encompass a variety of malformations and tumors that can result in severe morbidity and mortality in both adults and children. Advances have been made in the classification and diagnosis of these anomalies, with the International Society for the Study of Vascular Anomalies establishing a widely recognized classification system. In recent years, notable progress has been made in genetic testing and imaging techniques, enhancing our ability to diagnose these conditions. The increasing sophistication of genetic testing has facilitated the identification of specific genetic mutations that help treatment decisions. Furthermore, imaging techniques such as magnetic resonance imaging and computed tomography have greatly improved our capacity to visualize and detect vascular abnormalities, enabling more accurate diagnoses. When considering reconstructive surgery for facial vascular anomalies, it is important to consider both functional and cosmetic results of the procedure. Therefore, a comprehensive multidisciplinary approach involving specialists from dermatology, radiology, and genetics is often required to ensure effective management of these conditions. Overall, the treatment approach for facial vascular anomalies depends on the type, size, location, and severity of the anomaly. A thorough evaluation by a team of specialists can determine the most appropriate and effective treatment plan.

  • Epithelioid hemangioendothelioma (EHE) is a low-grade malignant vascular neoplasm that can occur anywhere in the body. EHE has a low annual incidence (0.38/106) and prevalence (< 1/106), and primary mediastinal EHE is exceedingly rare. We report a case of EHE in a 53-year-old female which manifested as an incidentally discovered mass in the right paratracheal region. In this report, authors describe the pathological and radiological findings of primary mediastinal EHE invading the superior vena cava in the right paratracheal area.

  • Castleman's disease is a relatively rate disorder of lymphoid tissue and poorly understood etiology. The disease may occur anywhere along the lymphatic chain, but is most commonly found as a solitary mass in the mediastinum. The hyaline vascular type represents 91% of Castlemen's disease, and these are most often discovered in the asymptomatic patient on routine chest film. Patients with the plasma cell type often exhibit systemic symptoms, including fever, night sweats, anemia, and hypergammaglobulinemia. Surgical excision effects cure, although resection of the hyaline vascular type may be associated with significant hemprrage owing to extreme vascularity. We recently experienced a case of hyaline vascular type Castleman's disease which was treated by surgical resection through the anterior mini-thoracotomy, and report with its review.

They are uncommon, potentially malignant tumors, and in the lung, the tumors may present as a small asymptomatic nodule or a large symptomatic lesion. Recently we experienced two cases of solitary pulmonary vascular tumors(epithelioid hemangioendothelioma and hemangiopericytoma), and reviewed them with references.

  • Primary hemangiopericytoma of chest wall is very rate and only a few cases have ever been reported. The tumor aries from the capillary pericyte of Zimmerman. It is a highly vascular slow growing tumor which can be calssified as both malignant and benign varieties. We report a case of a 66 year-old man in whom recurrent hemangiopericytoma was treated by complete surgical excision. In October 1993 he had received surgical excision of hemangiopericytoma on posterior chest wall. For more than 6 years after the operation he was in good condition until a recurrent mass was found on the chest X-ray. The patient was discharged 9 days after the operation and is receiving radiotherapy.

  • Arteriovenous malformations are vascular anomalies containing a communication between artery and vein without an intervening capillary bed and also are the most dangerous of vascular malformations being hemodynamically active. Treatment must be careful usually limited and considered in the phase of activity of hemodynamics. The patient was 29-year-old female and had no specific signs and symptoms except buldging, pal- pable mass on the right posterolateral chest wall from several years ago and it was gradually growing from that time. The operation was done with ligation of the right 9th, 1 Oth intercostal arteries and dissection from other normal tissues and then excised the arteriovenous malformation mass and its feeding vessels. The pathologic result was arteriovenous malformation.

  • Lymphangioleiomyomatosis(LAM) is defined as an abnormal proliferation of smooth muscles in the lung tissue throughout lymphatics, vascular and bronchial structure. A 52-year-old postmenopausal woman was admitted to our hospital for recurrent pneumothorax. She was treated for medroxyprogesterone by LAM 1 month ago. We performed operation of pulmonary partial resection and pleurodesis. The patient is receiving continuous medroxyprogesterone and Leuplin administration, and currently, 6 months after the operation, is still showing good results.
