Intracardiac hemangiomas are very rare primary cardiac tumor and there have been at least 37 reports of surgically resected cardiac hemangiomas. Most cardiac hemangiomas are asymptomatic. In symptomatic patients, symptoms are related to the location of tumor and outflow tract obstruction or obstruction of inferior and/or superior vena cava. Sudden death may occur due to conduction disturbances. The principle of treatment is surgical resection, and the prognosis is dependent upon the size, location and multiplicity of the tumor. A 40 year old man was admitted due to chest contusion and was found to have an intracardiac mass during echocardiographic examination. The mass was successfully removed and pathologic examination showed benign hemangioma. The patient was recovered uneventfully in postoperative period and was followed up for 1 year without evidence of recurrence.

Primary pulmonary arterial sarcomas, especially those originating from the pulmonary valve are extremely rare. A 35 year-old male patient was admitted for exertional dyspnea and fatigue. Large intraluminal mass in the main pulmonary artery and both pulmonary arteries was detected by chest computed tomogram, chest magnetic resonance imaging, echocardiogram, and pulmonary angiogram. We regarded the mass as a primary pulmonary arterial malignant tumor, and resected under cardiopulmonary bypass. The mass was appeared to originate from the posterior cusp of pulmonary valve, and extended from below pulmonary valve to main pulmonary artery and both pulmonary arteries. We resected the mass by pulmonary endarterectomy and replaced the pulmonary valve. The mass was diagnosed as a pulmonary arterial sarcoma in histopathologic examination.

신경초종은 신경초에서 발생되는 성장이 느린 양성 종양으로 단발성이며 드물다. 이 종양은 말초 신경,자율 신경,뇌신경의 Schwann세포에서 발생된다. 두경부 영역의 두개외 신경성 종양은 드물며 특히 타액선에서 발생되는 예는 드물다. 저자들은 20세 여자 환자에서 아래와 같은 소견을 나타내는 신경초종을 경험하였기에 보고하는 바이다. 1.주소는 좌측 악하선 부위의 종창이었으며 촉진시 3×4㎝의 단단한 종괴가 만져졌으나 동통이나 림프절병증은 없었다. 2. 일반방사선사진에서 종괴와 관련된 골변화는 없었으나 초음파 영상에서는 불균질한 반사 양상을 보이는 종괴가 좌측 악하선 영역에서 관찰되었다. 3. 자기공명영상으로 병소의 정확한 위치를 확인할 수 있었다. 병소의 경계는 명확하였으나 신호 강도는 균일하지 않았으며 T1 강조 영상에서는 근육과 유사한 신호 강도를 보였으나 T2 강조 영상에서는 근육보다 높은 신호 강도를 나타냈다. 4. 조직 병리학적으로 Antoni type B 부위보다는 A 부위가 지배적이었으며 Verocay body도 나타났다. 종양 세포는 anti-S-100 염색에 양성으로 반응하였다.

Metastases from hepatocellular carcinoma (HCC) can be found in the multiple organs including adrenal gland. But adrenal metastasis of HCC without obvious hepatic lesion is very rare. We report CT and MR findings of a patient who presented with adrenal metastasis as the first clinical manifestation of HCC. Signal intensity and enhancement pattern of adrenal metastastic mass of HCC were similar to those of HCC on MRI.

Central anticholinergic syndrome is defined as an absolute or relative reduction in cholinergic activity in the central nervous system and has a wide variety of manifestations. It is associated with almost any drug given during anesthesia, except neuromuscular relaxants, and treated with the cholinesterase inhibitor physostigmine. The diagnosis of central anticholinergic syndrome is often made when symptoms resolve promptly after the administration of physostigmine. We present a case of a central anticholinergic syndrome diagnosed by treatment with physostigmine, in a patient who received closure of patent foramen ovale associated with stroke.

Ganglionic cyst is the most common benign tumor in the wrist and hand, and easily diagnosed with ultrasonography. Ganglionic cyst in sonography usually appears as hypoechoic or anechoic with well-demarcated cystic mass. We report a case of the hyperechoic mass at the volar aspect of the wrist, which confirmed as ganglionic cyst by operative and histological findings.

A 34-year-old male was admitted to our hospital complaining of chest pain. Chest computerized tomography showed pleural effusion and mass in left lower area. After open thoracotomy and mass removal originating from the parietal pleura were done. The mass was pathologically diagnosed as poorly differentiated synovial sarcoma. Synovial sarcoma of the pleura is rare. Herein we report a case of synovial sarcoma of the parietal pleura.

Inflammatory myofibroblastic tumor was widely known as inflammatory pseudotumor, commonly developed as a solid mass in lung. The endobronchial inflammatory myofibroblastic tumor is a very rare case where only a few cases have been reported. We report a 13-year-old girl who had coughing for 5 months. The simple chest X-ray and computued tomography of the chest revealed a mass which obstructed the right lower lobe bronchus and pneumonic consolidation. The fiberoptic bronchoscopic finding was mostly gelatinous, gray-yellowish mass that obstructed the airway of right lower lobe bronchus nearly, and was considered as a chondroid hamartoma pathologically. Right lower lobectomy of lung was performed. The mass was confirmed as a endobronchial inflammatory myofibroblastic tumor The patient was discharged without complication and with outpatient followup.

Giant thymic Hyperplasia is a rare lesion in children. We report a case of giant thymic hyperplasia in the right anterior mediastinum in a 2 year-old male patient. Presenting symptom was frequent cough and sputum, plain chest X-ray and computed tomography showed huge mass in the right anterior mediastinum. The tumor resection was done through a median sternotomy for the prevention of progression to atelectasis caused by mass effect and tissue diagnosis. An open biopsy specimen showed normal thymic architecture. The patient recovered without any problem and is doing well untill now. We report this rare case of giant thymic hyperplasia with review of the literature.

Desmoplastic small round cell tumor (DSRCT) is a rare and highly malignant mesenchymal tumor found in the abdominal cavity. It mainly affects young male patients. We report a case of DSRCT that occurred in the abdominal cavity of a 50-year-old man. The tumor was characterized by small round tumor cells with irregular nests in the prominent desmoplastic stroma. The tumor cells showed immunoreactivity for epithelial membrane antigen, desmin, vimentin, and neuron specific enolase.
