Background : Lymphangioma of the mediastinum is an uncommon benign tumor of lymphatic origin that is most often seen in children, is very rare in adults and is frequently discovered incidentally on chest x-ray exams. While radiology (CT and MRI) may suggest the diagnosis and allow an assessment of the operative difficulties, the histology of the surgical specimen is required for precise diagnosis. Complete resection is the only treatment; however, in some patients resection was incomplete because of the infiltrating character of these tumors, leading to recurrence. We report three cases of mediastinal lymphangioma with a review of the literature.

Purpose To assess the predictive factors and describe the imaging features of mediastinal lymph node (MLN) metastases in patients with head and neck cancer. Materials and Methods We compared the clinical features and disease characteristics (sex, age, site of primary tumor, histologic type, history of prior treatments, TNM stages, and metastasis in cervical LNs) of patients with head and neck cancers between the MLN metastasis and no MLN metastasis groups. We also evaluated the chest CT (distribution and maximum dimension of the largest LN) and PET/CT (maximum standardized uptake value) features of MLN metastases based on the MLN classification. Results Of the 470 patients with head and neck cancer, 55 (11.7%) had MLN metastasis, involving 150 mediastinal stations. Hypopharynx cancer, recurrent tumor, T4 stage, N2/N3 stages, and M1 stage were found to be significant predicting factors for MLN metastasis. The most common location of MLN metastasis was ipsilateral station 2 (upper paratracheal LNs, 36.4%), followed by ipsilateral station 11 (interlobar LNs, 27.3%) and ipsilateral station 10 (hilar LNs, 25.5%). Conclusion Metastasis to MLNs should be considered in patients with head and neck cancer, especially in cases that are associated with a hypopharyngeal cancer, recurrent tumor, and high TNM stages.

Pulmonary carcinosarcon!as are rare malignant tumors consisting of an admixture of epithelial and mas- enchymal elements of the type ordinarily seen in malignancies of adults. Compared with all pulmonary neoplasms it occurs with a frequency of 0.3% and has a strong association with smoking. Carcinosarcomas be divided into two clinicopathologic groups based on the locution of the lung: a solid parenchymal type and a central or endobronchial lesion Noninvasive diagnostic tests have a rather low yield in detecting carcinosarcoma. The most frequent metastatic sites are hilar and mediastinal Lymph nodes. Surgical resection is both diagnostic and the initial treatment. The prognosis is poor and average postoperative survival is 9 months. We report one case of pulmonary carcinosarcoma demonstrated by immunohlstochemical staining in a 61 year old male patient with a review of literatures.

Lobectomy with mediastinal node dissection has been standard treatment for non-small cell lung cancer (NSCLC). Nowadays, video-assisted thoracoscopic surgery (VATS) is gaining acceptance as an alternative treatment option, given the quality-of-life benefits that it confers. For the VATS procedure, most surgeons create two or three ports with a utility incision of 3 to 5 cm. However, with acquired skill and instrumentation advances, single-incision thoracoscopic surgery has emerged over time. Here, we report the case of an 86-year-old female with NSCLC treated by single-incision segmentectomy.

Von Recklinghausen's disease is a systemic hereditary disorder with varied manifestations in bone, soft tissue, nervous system, and skin, the most common of which is the developement of multiple, small, cutaneous tumors with a characteristic histologic picture. Tumors develop after birth and before puberty in most cases, and they increase in number until old age. Malignant neoplasms that complicate multiple neurofibromatosis include gliomas of the optic nerve, astrocytomaas of the cerebral and cerebellar hemispheres, and sarcomas of peripheral nerves (femoral, tibial and intercostal nerves) and somatic soft tissues. Little attention has been paid to the presence of cystic lung disease in association with neurofibromatosis. Currently, most think of thoracic involvement in neurofibromatosis in terms of posterior mediastinal neuroma, pheochrocytoma, meningocele or, less commonly parenchymal pulmonary neurofibromas. Author have experienced 2 cases of Von Recklinghausen's disease. One case developed a hyge malignant Schwannoma in the parietal pleura of left 4th intercostal space and multiple benign neurofibromas (two in intercostal spacees and one in the neck) , and the other has several episodes of pneumothorax resulting from diffuse cystic lung disease which required closed thoracotomy drainage.

A case report of lymphangiohemangioma of the mediastinum that was misdiagnosed as thymic origin mass on chest CT and MR angiography. Operative finding revealed vascular proliferation originated from innominate vein and the pathologic finding showed both lymphatic and vascular component which was diagnosed lymphangiohemangioma.

The peritoneum is the most frequent site of recurrence for gastric cancer after gastrectomy, followed by the liver and lymph nodes. In contrast, metastasis to the thymus is rare. Annual surveillance with computed tomography was performed on a 67-year-old man who previously underwent a distal gastrectomy and D2 lymph node dissection for gastric cancer at Tottori University. Five years after the initial operation, an anterior mediastinal tumor was detected by computed tomography. The patient underwent video-assisted thoracic surgery to remove the tumor. Histopathology revealed adenocarcinoma cells similar to those of the gastric cancer resected 5 years previously. Thymic metastasis was considered likely based on the location of the tumor. The recognition that gastric cancer can metastasize to unusual anatomic locations, such as the thymus, can facilitate an accurate, prompt diagnosis and appropriate treatment.

Pleuropulmonary blastoma (PPB) is a rare intrathoracic neoplasm, found solely in childhood. The usual symptoms are dyspnea, chest discomfort, recurrent respiratory infections, fever, dry cough, and chest pain. The progress of PPB is usually aggressive and its progress is generally poor. Lymphatic spread to the hilar and mediastinal nodes can occur Distant metastasis is found in brain, bones, and intra-abdominal organs. Surgical resection is the treatment of choice. When the disease Is too extensive for surgical resection, neoadjuvant chemotherapy can be used. We report 2 cases of pleuropulrnonary blastoma in children successfully treated with multimodal therapy.

Primary neoplasms of the trachea are rare, but are a very serious critical life-threatening disease. Nearly all the lesions of the trachea are presented as obstructive lesions. Bronchoscopic examination including chest C-T, tomogram and air tracheogram are essential for the further definition of these lesions. The need for removal of tracheal tumors whether complete or incomplete, is clear enough regardless of the histology of the tumor. We have experienced 9 cases from Jan. 1965 to June, 1985. One patient with tracheal hamartoma was cured with complete resection through rigid bronchoscopy and another patient with fibrous histiocytoma was treated with re-excision and laser evaporation through superior mediastinotomy due to recurrence, 1 year later. The remaining patients were treated with mass excision or segmental resection and end-to-end anastomosis through collar incision and superior mediastinal sternotomy. The remaining two patients were operated with and segmental resection and end-to-end anastomosis of trachea using partial cardiopulmonary bypass. The histologic diagnosis were adenoid cystic Ca[5], fibrous histiocytoma[1], mucoepidermoid Ca[1]. hamartoma[1], anaplastic Ca.[1]. Three patients were treated post-operatively with radiation; with adenoid cystic Ca.[2] and anaplastic Ca.[1]. Their post-operative courses were uneventful during the follow-up from 2 months to 7 years.

Chylopericardium is a rare disease entity characterized by the accumulation of chylous fluid in the pericardial sac. It usually arises from mediastinal neoplasms, thrombosis of the subclavian vein, tuberculosis, nonsurgical trauma, thoracic or cardiac surgery. The spectrum of symptoms for chylopericardium varies from an incidental finding of cardiomegaly to dyspnea, upper abdominal discomfort, cough, chest pain, palpitation, fatigue. However, most of the patients are asymptomatic. The main purpose of treatment of chylopericardium is the prevention of cardiac tamponade and prevention of metabolic, nutritional, and immunological compromise due to chyle leak. Here, we report a case of chylopercardium secondary to lymphangiomyoma with review of the literature.
