Abstract PDF: Lymphangioma is a congenital abnormality of the lymphatic system detected primarily in early childhood. There are rare reports of mediastinal lymphangioma in older adults. We hereby report on a 66-year-old female patient who underwent kidney transplantation 20 years previously and who developed pathologically confirmed solitary mediastinal lymphangioma 1 year ago. Chest radiography showed a mediastinal nodule, which was not observed 2 year previously, therefore she was referred to the pulmonary division. She had no symptoms, and chest computed tomography demonstrated a 25-mm, well-defined, low-density nodule located at the anterior mediastinum. The size of the nodule had increased from 25 mm to 34 mm 1 year later, and it was completely resected via video-assisted thoracic surgery. The histological diagnosis was cystic lymphangioma. Therefore, we recommend that clinicians consider cystic lymphangioma as a possible diagnosis even in older patients with a mediastinal cystic mass that shows progressive enlargement.

A Case of Synovial Sarcoma in Mediastinum.: Yong Hoon Yoon, Dong Uk Kang, Eun Jeong Gong, Sang Yong Om, Jin Seo Lee, Ji Won Lyu, Woo Sung Kim; Yeungnam Univ J Med. 2013;30(1):51-54. Published online June 30, 2013; DOI: https://doi.org/10.12701/yujm.2013.30.1.51

Abstract PDF: Synovial sarcoma is a rare malignancy in the thoracic cavity, especially in the mediastinum. In this paper, a case of primary mediastinal synovial sarcoma is reported. A 34-year-old woman was hospitalized with dyspnea. Her chest X-ray and computed tomography (CT) showed a 16x13x11 cm mass in her anterior mediastinal space. Surgical resection was performed but was incomplete. The pathological and immunohistochemical analysis confirmed the diagnosis of monophasic spindle cell synovial sarcoma. The patient underwent adjuvant radiotherapy for two months, but local recurrence and metastasis occurred in her pleural cavity. She eventually underwent chemotherapy for one year and died 18 months after her operation.

Review

Anterior Mediastinal Tumor.: Jae Kyo Lee; Yeungnam Univ J Med. 2010;27(2):98-104. Published online December 31, 2010; DOI: https://doi.org/10.12701/yujm.2010.27.2.98

Abstract PDF: Primary anterior mediastinal neoplasms comprise a diverse group of tumors and account for 50% of all mediastinal masses. Thymic epithelial neoplasm are most common and classified into thymoma, invasive thymoma, and thymic carcinoma. Neuroendocrine differentiation of thymic epithelial neoplasm are rare malignancies. Germ cell tumor (GCT) is second most common anterior mediastinal tumor and most of them are mature cystic teratoma. Malignant mediastinal GCT are rare than benign. Primary thoracic lymphoma is rare than thoracic involvement of systemic lymphoma and most common location of primary thoracic lymphoma is anterior mediastinum. The clinical and radiologic appearance of the most common masses are reviewed.

Case Reports

A Case of Nonfunctioning Paraganglioma of the Posterior Mediastinum.: Young Chul Mun, Sung Keun Yu, Hye Jung Park, Kyeong Cheol Shin, Choong Ki Lee, Jin Hong Chung, Kwan Ho Lee, Mee Jin Kim, Jung Cheul Lee; Yeungnam Univ J Med. 2000;17(2):155-160. Published online December 31, 2000; DOI: https://doi.org/10.12701/yujm.2000.17.2.155

Abstract PDF: Paraganglioma is a tumor from the extra adrenal paraganglion system and is rarely observed in the mediastinum. The authors experienced a case of nonfunctioning paraganglioma of the posterior mediastinum. The patient was 34-years-old male in whom abnormal mass lesion was nites in chest radiograph with hemoptysis. His blood pressure and serologic examination were within normal range upon admission to our hospital. Chest CT revealed a tumor in the left lower lobe. Diagnostic thoracoscopy was performed and diagnosed a posterior mediastinal mass. Surgical resection was them performed. Posterior mediastinal mass was removed successfully and histological examination of the surgical specimen diagnosed paraganglioma. He received radiotherapy after surgery and was followed up. Related literature are reviewed.

Radiologic findings of mediastinal fibromatosis.: You Song Chang, Jae Ho Cho, Kil Ho Cho, Mee Soo Hwang, Bok Hwan Park; Yeungnam Univ J Med. 1991;8(2):217-221. Published online December 31, 1991; DOI: https://doi.org/10.12701/yujm.1991.8.2.217

Abstract PDF: The fibromatosis is a rare timorous with local invasion, but is not metastasized distantly. This term should not be applied to nonspecific reactive fibrous proliferations that are part of an inflammatory process of are secondary to injury of hemorrhage and have no tendency toward growth or recurrence. It arises principally from the connective tissue of muscle and overlying fascia or aponeurosis (musculoaponeurotic fibromatosis), and chiefly affects the muscle of shoulder, pelvic girdle, and extremity. The term 'aggressive fibromatosis' is also employed to describe this disease, but it is impossible to predict the clinical course in the individual case. The fibromatosis arising in the mediastinum is very rare, and the report about it is nearly absent. The plain radiography shows merely mass with soft tissue density. The CT demonstrates a poorly defined homogenous or heterogeneous mass, isodense with skeletal muscle on precontrast-images, and slightly hyperdense to muscle on postcontrast-scan. Accurate delineation between the tumor & surrounding tissue is vague or frequently impossible. The authors experienced one case of the mediastinal fibromatosis recently and report the case with review of concerned literature.
