The formation of postlaminectomy arteriovenous fistula is unusual and the rongeur during discectomy with resultant simultaneous damage to artery and vein is causative. The delay in diagnosis is particularly distressing. The presence of a palpable abdominal thrill or bruit with or without congestive heart failure should results in a high index of suspicion of this entity. Prompt recognition and surgical closure of the post-laminectomy arteriovenous iliac fistula are most important in successful management.

The hamartoma is the commonest benign tumor of the lung and proved incidentally as asymptomatic coin lesion on routine chest radiologic examination, but has very low incidence, especially in endobronchial origin. The authors experienced a case of coincidental with intrapulmonary and endobronchial hamartoma. The patient, a 60-year-old man, a farmer, was admitted due to coughing and fever. Preoperative diagnosis was achieved by flexible bronchoscopic biopsy and managed by right middle lobectomy. Three lobulated masses were palpable in the right middle lobe. He was discharged on 15th postoperative day, without problem.

21 cases of the chest wall tumors that were operated and proved by pathologically at the dept. of thoracic & cardlovascular surgery, SNUH during 16 years from 1965 to 1981 were reviewed. The results are as follows: 1.Benign tumors were 11 cases. Primary malignant tumors were 7 cases. Metastatic tumors were 3 cases. 2.Incidence rate of male to female was 1.5:1. 3.Main symptoms were palpable mass [52.4%] and localized chest pain [14.3%]. 4.Locations of tumors were rib [61.9%], soft tissues and muscle [33.3%] and sternum [4.8%]. We excluded the Tbc, rib carles from the chest wall tumors.

Primary hepatocellular carcinomas are rare in dogs. A 12-year-old 5.4 kg female Poodle was referred to the Veterinary Medical Teaching Hospital with abdominal distension and mild anorexia. In this case, an extensive soft tissue mass was clearly palpable in the upper abdomen and radiography revealed a spherical mass of soft tissue density in the abdomen but its origin was not clear. In following an exploratory laparotomy, a partial hepatectomy was performed. Surgical complications were minimal. The survival time was seven months before dyspnea lead to a sudden and rapid decline.

Posterior mediastinal goiter extending to carotid sheath posteriorly is rare. Recently we experienced two cases of posterior mediastinal goiter presenting dyspnea due to tracheal compression. The one was a 48-year-old female with mediastinal tumor shadow on chest roentgenogram . The other was a 54-year-old female with palpable mass on neck and huge mediastinal mass. These masses were resected completely through the right posterolateral thoracotomy and median sternotomy respectively. The postoperative courses were uneventful.

The maximum current level in organic light emitting diodes (OLED) panel influences the maximum pixel luminance, the width of $V_{DD}$ lines, the maximum power consumption and the lifetime. We propose an algorithm that limits the overall current without any palpable image artifacts, and therefore, improve panel parameters by program.

Paratesticular liposarcoma is a very rare tumor that is typically reported as isolated cases of or as components of larger studies of liposarcomas. Image findings are similar to those of other anatomic sites, but in less-common sites, their appearance may be less familiar, and they may be mistaken for other pathologies. In addition, atypical image findings of liposarcoma make diagnosis more difficult. Herein, we report on the case of a 45-year-old male patient who presented with a painless, palpable mass in the right scrotum. The patient was diagnosed with paratesticular liposarcoma by excisional biopsy.

This is one case report of surgically treated partial atrioventricular canal. The 22 year-old male patient had no definitive history of frequent respiratory infection and cyanosis in his early childhood. Since his age of 7 years, dyspnea was manifested on exertion. First appearance of congestive heart failure was at his age of 16 years old. The physical examination revealed that the neck veins were distended and heaving of precordium. A thrill was palpable on the left 3rd-4th intercostal space extending from the sternal border toward the apex and Grade IV/VI systolic ejection murmur was audible on it. Neither cyanosis nor clubbing was noted. Liver was palpable about 5 finger breadths. Chest X-ray revealed increased pulmonary vascularity and severe cardiomegaly (C-T ratio = 74%). EKG revealed LAD, clockwise rotation, LVH and trifascicular block. Echocardiogram showed paradoxical ventricular septal movement, narrowed left ventricular outflow tract and abnormal diastolic movement of the anterior leaflet of mitral valve. Right heart catheterization resulted in large left to right shunt (Qp : Qs = 5.7: 1), ASD and moderate pulfllonary hypertension. Finally, left ventriculogram revealed typical goose neck appearance of left ventrlcalar outflow tract. On Oct. 10, 1980, open heart surgery was performed. Operative findings were: 1. Large primum defect ($6{\times}5$ Cm in diameter) 2. Cleft on the anterior leaflet of mitral valve. 3. The upper portion of ventricular septum was descent but no interventricular communication. 4. Downward attachment of the atrioventricular valves on the ventricular muscular septum. 5. Medium sized secumdum defect ($2{\times}1$ Cm in diameter). The cleft was repaired with 4 interrupted sutures. The primum defect was closed with Teflon patch and the secundum defect was closed with direct suture closure. Postoperatively atrial flutter-fibrillation in EKG and Grade U/VI apical systolic murmur were found. The postoperative course was uneventful and discharged on 29th postoperative day in good general conditions.

Purpose: Lymphoma originated from mucosa associated lymphoid tissue(MALT) is most common in gastrointestinal system, and rarely found in salivary gland, thyroid, bronchus or orbit. We experienced a case of MALT lymphoma which was originated from conjunctiva and involving lower eyelid without metastasis. Methods: A 40-year-old man suffered palpable mass on right lower eyelid without pain. Orbital computed tomographic and ultrasonographic findings showed a conical mass($1.9{\times}1.2{\times}0.9cm$ size) inside lower eyelid. The mass was completely excised under local anesthesia and histopathological examination was followed. Results: Microscopic finding showed a multiple follicular colonization. In the follicle, small lymphocytes and plasma cells differentiated to centrocyte-like cell, monocyte B cell, plasma cell were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. After excision, SPECT, abdominal CT was carried out and there were no evidence of extraorbital disease. Conclusion: Biopsy and pathological examination should be performed in patients who complain palpable mass on lower eyelid because of possibility of MALT lymphoma. Although MALT lymphoma is rarely metastasized, it is necessary to evaluate the extraorbital involvement using SPECT or other radiologic exams. For detecting extraorbital involvement, periodic follow-up examination is need.
