Askin tumor is an uncommon malignant neoplasm in the thoracopulmonary region mainly occurring in children and adolescents. Four young patients with histologically proven Askin tumors were treated in our hospital. In all patients, chest computed tomography imaging demonstrated a chest wall mass with or without destruction of ribs. All patients underwent radical mass resection and postoperative c...

Actinomycosis is an uncommon disease in children and most cases are cervicofacial infections. To date, there have been only a few reports on children with chest wall involvement due to actinomycosis. Here we report a 9-year-old girl with a mass lesion in the chest wall mimicking Ewing's sarcoma of the rib. Thoracic actinomycosis without typical features of the disease is often evaluated with th...

Synovial sarcomas are the fourth most common malignant soft-tissue tumors, and typically develop in para-articular locations of the extremities. Other less common sites include the head and neck, abdominal wall, intra-abdominal cavity, and mediastinum. However, the occurrence of these tumors in the chest wall is rare. In this article, we report the interesting case of a 31-year-old male with mo...

A 72-year-old man with a history of brain infarction presented with left sided anterior chest pain secondary to a thymic carcinoma. He received induction radiotherapy, 45 Gy. Preoperative computed tomography showed the tumor was adherent to a thoracic aortic aneurysm (TAA) which had extensive mural thrombus and calcification. To obtain adequate exposure without exerting tension on the fragile a...

Phyllodes tumors are rare fibroepithelial neoplasms of the breast. In the literature, borderline or malignant tumors have been reported to present with unusual characteristics including a short clinical history and extremely rapid tumor growth. Skin necrosis and infection sometimes accompanies these malignancies. Giant phyllodes tumors have a good prognosis when treated with total mastectomy, b...

A 27-year-old female presented with a history of a right chest wall tumor at 3 years of age. At that time, the tumor was surgically resected and diagnosed as Ewing's sarcoma (EWS), and postoperative chemoradiotherapy was administered. The patient remained disease-free for 25 years. At age 27, chest computed tomography revealed a mass adjacent to the anterolateral thoracic wall. After surgery, t...

Abdominal-based free flaps are commonly used for breast reconstruction, and the internal mammary or thoracodorsal vessels are typically used as recipient sites. Conversely, free tissue transfer is less commonly used for chest wall reconstruction in the setting of chest wall recurrence, in part, because of a paucity of recipient vessels. Here, we describe a case of a 68-year-old female smoker wi...

Askin's tumor is a rare tumor arising from the chest wall. It is a subset of Ewing sarcoma characterized histologically by the presence of small round blue cells. It is a highly malignant tumor with guarded prognosis, which is dependent upon the extension of tumor at the time of diagnosis. A dual paper of Askin's tumors in young boys is being presented here.

BACKGROUND Large tumor motion often leads to larger treatment volumes, especially the lung tumor located in lower lobe and adhered to chest wall or diaphragm. The purpose of this work is to investigate the impacts of planning target volume (PTV) margin on Stereotactic Body Radiotherapy (SBRT) in non-small cell lung cancer (NSCLC). METHODS Subjects include 20 patients with the lung tumor locat...
