Extraskeletal osteosarcoma is an uncommon tumor originated from soft tissue without evidence of skeletal involvement. It usually affects adults and its common locations are extremity, buttock, and retroperitoneum. Although the histologic feature of this tumor is well known, there have been few reports on the fine needle aspiration cytologic findings. We report the imprint cytologic feature of extraskeletal osteosarcoma. The patient was a 49-year-old man with a mass of the left anterior chest for 2 years. On the Imprint preparation, the smears showed malignant round, polygonal or spindle cells with coarsely clumped chromatin and occasionally prominent nucleoli. The malignant cells occur singly, in clusters, or associated with amorphous eosinophilic osteoid. Mitotic figures are also seen.

Urinary tract infection (UTI) is most commonly diagnosed bacterial infection in febrile infants. Renal abscess is a very rare complication of UTI in children. Early diagnosis and treatment with appropriate antibiotics are important because renal scar correlates positively with the time of treatment. Renal ultrasonography and abdominal computerized tomography facilitates an earlier diagnosis and is also useful in establishing percutaneous drainage. Extended broad spectrum antibiotics therapy alone can be effective in most types of renal abscesses in infant, but some antibiotics-resistant cases need surgical drainage or nephrectomy. We report a case of a infant UTI, that progressed to renal abscess despite early antibiotic treatment and was treated with US guided percutaneous needle aspiration.

An adult female dog was presented for evaluation of mammary gland masses. Complete blood count and serum chemistry data were within normal limits. Fine-needle aspiration cytology of the mammary masses revealed clusters of malignant epithelial cells with clear cytoplasmic vacuoles. Based on histopathological findings, a diagnosis of lipid-rich mammary carcinoma was made. Approximately 5 weeks after surgical removal, the tumor recurred at the surgery site and metastasis to the tibia was detected. Due to the poor prognosis and deterioration of the condition, the dog was euthanized.

At OPD follow-up in December 1998, chest x-ray of a 42-year-old female showed a solit ary pulmonary nodule at a superior basal segment in the right lower lobe. After percut aneous transthoracic needle aspiration failure, wedge resection of the superior basal segment of lower lobe in right lung was performed for diagnosis and therapy. Three years ago, she had received surgery to remove a mass in the left buttock. The mass was pathologically diagnosed as malignant fibrous histiocytoma. She subsequently received 4500 rad radiotherapy for 35 days. Pathology confirmed metastatic malignant fibrous histiocytoma of the lung.

We have observed retroperitoneal hematoma after trigger point injections of quadratus lumborum in a patient with chronic low back pain. Severe flank pain and dyspnea was observed three hours after injection of local anesthetic and steroid to the trigger point of quadratus lumborum muscle. There was fuge hematoma in abdominal CT image around the right kidney, which displaced and compressed the kidney anteriorly. Following infusion of contrast media, extravasation through renal vein and IVC was notified. Patient had a past history of having been treated with platelet aggregation inhibitor and lower dose aspirin treatment after cerebral ischemia for a year, but coagulative function was within normal range. Patient was admitted 12 days for bed rest, pain control and transfusion. We need to take greater care with a frequent aspiration and exact direction of needle, during trigger point injection of quadratus lumborum, particu right side, to avoid vascular injury.

There were only a few reports of mercury on pulmonary artery. However, there is no data on surgery related mercury dissemination. The objective of the present article is to describe one case of postoperative injected mercury dissemination. A 19-year-old man presented severe neck pain including meningeal irritation sign and abdominal pain after injection of mercury for the purpose of suicide. Radiologic study showed injected mercury in the neck involving high cervical epidural space and subcutaneous layer of abdomen. Partial hemilaminectomy and open mercury evacuation of spinal canal was performed. For the removal of abdominal subcutaneous mercury, C-arm guided needle aspiration was done. After surgery, radiologic study showed disseminated mercury in the lung, heart, skull base and low spinal canal. Neck pain and abdominal pain were improved after surgery. During 1 month after surgery, there was no symptom of mercury intoxication except increased mercury concentration of urine, blood and hair. We assumed the bone work during surgery might have caused mercury dissemination. Therefore, we recommend minimal invasive surgical technique for removal of injected mercury. If open exposures are needed, cautious surgical technique to prohibit mercury dissemination is necessary and normal barrier should be protected to prevent the migration of mercury.

Clinical observation were performed on 25 cases of Mediastinal tumors or Cyst, those were admitted and treated at the Department of Thoracic and Cardiovascular Surgery, Korea University Hospital, during the 6 years period from March 1973 to March 1979. The following results are obtained. Of 25 cases, 19 patients were males and 6 patients were females. Range of age varied widely from 2 years to 72 years. Approximately 28% were younger than 15 years of age at the time of diagnosis. The common subjective symptoms of the patients were anterior chest pain [36%], coughing [27%], dyspnea and a few incidence of hemoptysis. Diagnostic procedures were posteroanterior and lateral chest roentgenorgrams, Chest tomograms, Brochograms, Esophagograms, Mediastinoscopy, Scalene and Axillary Lymph node biopsy, and Needle aspiration biopsy. In the histological distribution on Mediastinal tumors in order of frequency, Neurogenic tumor 6 cases [25%], Lymphoma 5 cases [21%], Bronchogenic cyst 4 cases [17%], Pericardial cyst 2 cases [8.3%], Teratodermoid tumor 2 cases [8.3%], and each one case of Rhabdomyosarcoma, Seminoma, Cavernous hemangioma, Anthracosis, Tuberculoma were noted respectively. Of 24 cases of the histologically confirmed Mediastinal tumors, 6 cases [24%] were malignant. Thoracotomy for removal of tumor or cyst was performed on 17 cases and offered cure of all benign tumors. In 6 cases of malignant tumors, Chemotherapy with Vincristine, Cyclophosphamide and Prednisolone was given to 1 case Lymphoma. There was no case of postoperative mortality.

Two hundred twenty one cases of open heart surgery were done in the Department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital from July, 1981 to October, 1984. 1.There were 154 cases [73%] of congenital anomalies and 57 cases [27%] of acquired valvular heart diseases. Among the congenital cases, 128 cases were acyanotic and 26 cases were cyanotic. Among the 57 cases of acquired valvular replacement surgery, 3 cases had open heart commissurotomy, one had Kay annuloplasty. 2.The age distribution of the congenital acyanotic anomalies ranged from 5 to 32 years with mean age of 12.8 years, the congenital cyanotic anomalies from 3 to 29 years with mean age of 14.2 years and the acquired valvular diseases from 9 to 51 years with mean age of 30 years. The difference of sex distribution was no significance. 3.Three methods for debubbling process were used in our institute, in 133 cases, the vent was inserted into the left ventricular apex, in 61 cases inserted into the left atrium through right superior pulmonary vein and in 17 cases used needle aspiration only. 4.For cardioplegia, the GIK solution was infused repeatedly from 30 to 40 minutes interval and brought excellent results for myocardial protection during open heart surgery. 5.Overall mortality was 7.6%. The mortality along with each disease is 1.56% in congenital acyanotic cases, 26.9% in congenital cyanotic cases and 12.3% in acquired valvular disease.

An unusual case of primary leiomyosarcoma at the left lower posterior chest wall with metastasis to the right lung parenchyme is presented. The patient was a 43-year-old man who was asymptomatic but a slow growing hard mass was noted at the left lower posterior chest wall. The chest computed tomography showed a tumor at the left lower posterior chest wall with multiple metastasis to the right lung. The left lower posterior chest wall mass was examined by percutaneous needle aspiration and it was revealed as rhabdomyosarcoma histologically. En bloc resection to the left lower posterior chest wall tumor and metastasectomy to the multiple nodules in the right lung were done and pathological examination finally revealed primary leiomyosarcoma at the left lower posterior chest wall with multiple metastasis to the right lung. Chemotherapy was scheduled as adjunctive measure.

Carcinoma ex pleomorphic adenoma is rare, aggressive, poorly understood malignancy that occurs in the salivary glands. The patient was 70-year-old male presenting ovoid elevated submandibular mass that has been present for 30 years and rapid growing for 6 months. The initial cytologic finding by fine needle aspiration biopsy showed highly malignant cells and the radiologic finding revealed a $3.6{\times}3.7{\times}4.8cm$ sized mass with cervical lymphadenopathy. After wide excision of submandibular gland and modified radical neck dissection, the histologic examination revealed that tumor was composed partly of a benign pleomorphic adenoma and partly of an adenocarcinoma component with areas of calcification and frequent angiolymphatic invasion. We present a rare case of adenocarcinoma ex pleomorphic adenoma with tumor thrombus in the submandibular gland.
