The authors reviewed clinical data and 50 pathologic specimens from 41 patients of prostate adenocarcinoma filed in the Department of Pathology, Hanyang University school of Medicine, in order to evaluate correlation between clinical stages and histopathologic grades of prostate adenocarcinoma. Each of five currently used grading systems were compared with clinical stages of prostate adenocarcinomas. The followings results were obtained: All of the grading systems were relatively well correlated with clinical progression of the tumon. Histologic grading systems including Gleason's grading system, Gleasons scoring system and M.D. Anderson system showed better correlation than cytologic grading system of Mostofi. Gaeta gradings system regarding both histologic and cytologic aspects of the carcinoma showed good correlation to clinical stage with correlation coefficient of 0.654. Combined scoring system of cytologic and histologic grades (Mostofi-M.D. Anderson combined scoring system) showed better correlation to the clinical stage than single individual grading s system. The author conclued that Gleasons histologic grading system with cytologic characteristics of tumor cells would represent best parameter of clinical progression of the prostate adenocarcinoma.

Urinary tract dilation is one of the most common side effects during pregnancy. This is primarily a physiologic phenomenon that is typically more prominent on the right side, and it is caused by hormonal changes and mechanical obstruction. Occasionally, urinary tract dilation leads to more serious urinary tract problems such as infection, obstructive renal failure and urinomas. Urinomas are also known as pararenal pseudocysts, and they generally occur as a result of urinary system disruption, but they only rarely occur with pregnancy. We report here on an unusual case of extremely large bilateral perirenal urinomas that were detected during the postpartum period. This was successfully resolved by percutaneous drainage and ureteral stents.

A case of extrapulmonary silicosis involving abdominal lymph nodes in a 62-year-old man is presented. The patient underwent subtotal gastrectomy and regional lymph nodes dissection for gastric adenocarcinoma of clinical stage III. On gross examination, two separate gastric adenocarcinomas and multiple enlarged lymph nodes mimicking metastatic lesion were noted. Microscopic examination of the enlaged lymph nodes revealed characteristic sclerohyaline silicotic nodules without metastatic adenocarcinoma. Chest roentgenogram showed diffusely scattered multiple tiny nodular lesions in the entire lung fields, particularly the posterior side of both upper lung fields. He had worked in a mine for 18 years and had been exposed to silica for 5 of those years. We report incidentally found, unusual case of extrapulmonary silicosis.

This is an autopsy case of a 6 month old girl who suddenly died of respiratory distress during sleep. She had suffered from mild but frequent episodes of common cold and was treated for eczema for several days. At autopsy, the heart was enlarged and weighed 100 gm. A firm and gray-white tumor, measuring 4.5 x 3.8 x 2.8 cm, was located in the interventricular septum and encroached upon the wall of left ventricle. The mass was well demarcated but was not encapsulated. Neither necrosis nor calcification was present. Microscopically the tumor was composed of haphazardly arranged bundles of collagen fibers and fibroblasts. Myocardial cells are intermingled with the fibroblasts at the margin of the tumor. Massive edema of the lung and congestion of the liver and spleen were pronounced.

Inflammatory myofibroblastic tumor(IMT) or inflammatory pseudotumor is a rare, solid tumor that most often affects children. This tumor is characterized by a spindle cell proliferation admixed with a variety of inflammatory cells. Although it has disputed nosology, a distinctive fibroinflammatory and even pseudosarcomatous appearance have been well appreciated. Herein, we report a case of IMT in the posterior mediastinum in a 19-year-old girl with clinical findings. The immunohistochemical and ultrastructural studies on the tumor cells are reported, and their distinctive characteristics are discussed in details.

Congenital scoliosis is defined as a lateral curvature of the spine caused by congenital anomalies of the vertebral development. In this study seventeen congenital scoliosis patients seen and treated by either Milwaukee brace or surgical intervention at Department of Orthopedic Surgery, Seoul National University Hospital from December 1972 to April 1978 were evaluated according to frequency of the curve pattern, character of the deformity, method of treatment and its correctability. The following results were obtained in this study. 1. Age distribution was from 2 to 39 years and mean age was 13.4 years. 2. The most common deformity pattern was hemivertebra in 8 cases (47.1%), unilateral unsegmented bar in 4 (23.6%) and mixed type in 3 (17.6%). 3. The most common curve level was thoracic in 6 cases (35.3%), followed by thoracolumbar in 4 (23.5%) and lumbar in 4 (23.5%). 4. The best corrected type by Milwaukee brace was trapezoid vertebra (29.4%) and then mixed type(26.1%), followed by block type (20%) and hemivertebra(2.3%). 5. The operative treatment was performed in the cases of unilateral bar and progressive type with Milwaukee brace. In terms of the correctability of the curvature, the surgical intervention was better than the conservative treatment, with the result of its average correction of 33.5% that is compared with 15.9% of Milwaukee brace. 6. Halofemoral traction was effectively applied in the cases of rigid and severe curve; the initial curve 76.3 degress with 21.3% of flexibility. 7. Loss of correction in operative treatment was 2.3 degrees (6.5%).

Aurthors have treated 77 cases of acute supp rative osteomyelitis since January 1972 until December 1979. Among them 69 patients had surgical treatment while 8 cases had antibiotic therapy only. 42 patients out of 69 surgically treated cases had fenestration operation, while 27 cases had multiple drilling operation to evacuate the bony abscess. In 15 cases Turkels bone biopsy needle was used to decompress the infected bones, and by It the abscess could be very effectively evacuated. After decompression with a Turkel needle by placing a small calibered polyethylene tube Into the lesion, the lesion was continuously irrigated with antibiotics solution. This procedure has proved to be very effective and a successful one which can easily be practised as an office procedure in the very poor and needy cases. Also when patients are seriously ill and/or other extensive surgery is not feasible, this simple procedure can easily be practised without hazard, Good end results without sequellae were abtained when early decompression with massive antiblotic therapy was instituted even by Turkel needle drainage.

The fluoroscopy-guided fine needle aspiration biopsy has been gaining widespread acceptance as a rapid and effective method to make a pre-operative diagnosis of mediastinal tumors including thymoma, malignant lymphoma, and metastatic carcinoma. Although thymoma is a most common tumor of the superior mediastinum, most cytopathologists are not experted in cytologic diagnosis of this tumor because of limited experience. In order to define the diagnostic cytologic features of thymoma, we have retrospectively reviewed imprinting smears and corresponding tissue sections from four cases of this tumor. All cases revealed an apparent biphasic pattern of epithelial cell clusters and lymphocytes with occasional branching capillary fronds extending from three dimensional epithelial cell clusters. Epithelial cell clusters predominated in one case and lymphocytes in two cases. Mixed epithelial cell and lymphocyte type represented in one of four cases. In the lymphocyte predominant type, the presence of epithelial cell clusters and small mature lymphocytes are helpful features to differentiate from a malignent lymphoma.
