Distal radioulnar is a part which has a rotational movement through the function of distal radioulnar joint and extensor carpi ulnaris. The injury mechanism in this area is usually a trauma largely due to traffic accidents. In general these injuries to the distal radioulnar joint are treated by a closed reduction. However, the isolated distal ulnar fracture without radial fracture, which is often called the night stick fracture, is difficult to treat by a closed reduction and a cast immobilization alone, especially if there is a displacement or fracture segment impinging soft tissue or severe comminution. Nonunion has been the frequent outcome with this method of treatment and limitation of rotation of forearm and distal radioulnar joint have occurred due to long period of immobilization or malunion. Thus, a different treatment modality such as open reduction and internal fixation and early active joint motion has arisen as a better treatment modality. In this study, 8 cases of isolated distal ulnar fracture without radial fracture have recieved the operation and the early active joint movement, if a displacement was present either at the time of injury or after the initial closed reduction. As a result, this method has enabled the patients to reduce the rate of complication of nonunion and to recover limitation of joint motion in a shorter time period.

Primary malignant parovarian epithelial tumors are extremely rare, with only 56 cases previously reported in the world literature. Most parovarian epithelial tumors are of paramesonephric (Mullerian) origin. In this article, we report the first case in the Korean literature of papillary serous cystadenoma of borderline malignancy from paramesonephric parovarian cyst. This case presented here is of particular interest since this neoplasm is rare. A 48-year-old female underwent a hysterectomy with bilateral adnexectomy and pelvic lymph node dissection for a cystic tumor of the right parovarian area. The tumor, measuring 13 cm in diameter, was apart from the ovaries, fallopian tubes and uterus. The cyst wall had well-developed smooth muscle layers. The cyst was lined with mildly atypical ciliated and non-ciliated low columnar cells compatible with those of paramesonephric origin. From the inner surface of the cyst several cauliflower-like structures projected into the lumen. They were of a predominantly papillary architecture covered by atypical epithelial cells with piling-up and occasional glandular growth. No destructive stromal invasion was identified.

This case report describes a paraganglioma of the cauda equina in a 37-year-old man, as documented by light microscopy and immunohistochemistry. The patient experienced low back pain of 3 years duration, with the recent onset of sciatic pain and altered sensation in the right leg. Magnetic resonance imaging of L4 vertebral level revealed an ovoid, solid mass in the cauda equina. The mass was measured 1.5 cm in the greatest diameter. The histologic appearance was characterized by organoid pattern with clusters of chief cells (zellballen). Immunohistochemically, tumor cells are positive for keratin, epithelial membrane antigen, vimentin, neuron specific enolase and chromogranin.

PURPOSE: Prostate volume has been known to be poorly correlated with other parameters used to assess benign prostatic hyperplasia(BPH), including symptom score, peak flow rate(Qmax), amount of postvoid residuals(PVR). The purpose of this study was to determine if measurement of the transition zone index(TZI) of the prostate correlated well with other clinical parameters in predicting the degrees of obstruction. MATERIALS AND METHOD: We prospectively evaluated 86 men with symptomatic BPH(mean age: 65.4 years) according to symptoms, Qmax, PVR, transrectal ultrasound volume of the entire prostate and the transition zone. TZI was determined as the ratio between transition zone volume(TZV) and total prostate 1 volume(TV). RESULTS: Age correlated with symptoms(r=0.29, p=0.006) and PVR(r=0.466, p=0.001); Qmax negatively correlated with age(r=-0.487, p=0.001), symptoms 1 (r=-0.28, p=0.007) and PVR(r=-0.36, p=0.001). Age also correlated with TV(r=0.4, p=0.001), TZV(r=0.435, p=0.001) and, TZI(r=0.36, p=0.001). There was a weak correlations between TV and symptom r=0.23), Qmax(r=0.28), and PVR(r=0.24); a stronger correlation were noted between TZ and symptoms(r=0.33), Qmax(r=-0.35) or PVR(r=0.28). There were significant correlation between TZI and symptoms(r=0.35), Qmax(r=-0.38) or PVR(r=0.30). Age, PVR, 721, and TZV were significantly greater and Qmax were significantly lower in severe (IPSS > or = 20, N=38) symptom group than in moderate(IPSS < or = 19, N=48) one. (p < or = 0.01). On the other hand, the age, PVR, symptom score, TZI, and TZV in low Qmax( < or = 10ml/sec) group were significantly greater than in high Qmax ( > or = 15m1/sec) group. No significant differences of TV were noted either between moderate and severe symptom group or low and high Qmax group. CONCLUSIONS: Transition zone volume or index are parameters that correlates significantly with evaluated parameters of BPH and may serve as a useful method for evaluating obstruction. Studies are underway to determine if transition zone index can be used prospectively to predict and correlate response with therapies designed to ablate prostatic tissue medically or surgically.

Primary extranodal lymphoma of the liver is very rare, approximately thirty-one cases having been reported in the literature. We report one case of primary malignant lymphoma of the liver in a 26-year-old female, who was presented with palpable abdominal mass on the epigastrium for about 40 days. Laboratory findings revealed no specific abnormalities. Peripheral lymph nodes or spleen were not palpable. An abdominal ultrasonogram revealed a huge mass involving the entire left lobe of the liver. Left lateral segmentectomy of the liver was done. The resected lateral portion of left lobe of the liver showed a large solitary mass, 12 cm in the greatest dimension, with a yellowish gray fleshy solid cut surface. Though light microscopic feature was compatible with primary malignant lymphoma, diffuse large cell type, intermediate grade by the working formulation, undifferentiated carcinomas including hepatocellular carcinoma, plasmacytoma, and pleomorphic sarcomas could not be completely ruled out. Thus, marker studies and electron microscopic examination were performed. Immunoperoxidase stains for common leukocyte antigen was positive, and the Leder stain for myeloid granule was negative. Electron microscopic stuids revealed findings of neoplastic lymphoid cells, consistent with malignant lymphoma. Primary lymphoma of the liver has only rarely been reported, and its natural history is unclear. Many of the reported cases have been large cell lymphomas, as in this case.

We report a case of necrotizing arteritis involving the gallbladder. This case was clinically diagnosed as cholelithiasis with cholecystitis, and necrotizing arteritis was found in the surgically resected specimen. Vascular changes were similar to those seen in classic polyarteritis nodosa, involving medium-sized muscular arteries and characterized by fibrinoid necrosis and panarterial and periarterial inflammation varying from active to resolving stages. Acute cholecystitis is a rare initial clinical manifestation of the systemic vasculitis. If acute cholecystitis is found in the absence of obvious cause, careful examination is essential. Since steroid therapy improves the prognosis in the systemic vasculitis, clinicians and pathologists should be aware of this unusual lesion.

BACKGROUND: There are several ways to treat for recurrent pericardial effussion and cardiac tamponade due to malignancy. They are repeated pericardiocentesis, pericardial instillation of sclerosing and chemotherapeutic agents, surgical creation of a pericardial window and transthoracic pericardiectomy. Surgical techniques are usually effective but bear a significant morbidity and mortality especially in chronic debilitating cancer patients. So percutaneous balloon pericardial window as an alternative to surgery in these patients. METHODS: After pericardiocentesis was performed, a 0.035 inch J-tip guidewire was advanced into the pericardial space. And a pigtail catheter was advanced over the wire. A moderate amount of pericardial fluid were removed. A nd then the pigtail catheter was withdrawn and 8F sheath was inserted. A20mm diameter, 4cm long(Single balloon method) or two 10mm diameter, 4cm long balloon dilating catheter(Double balloon medium) was advanced over the wire to straddle the parietal pericardial border though the sheath. Several inflations of the balloon with a solution containing 50% radiographic contrast medium were performed until disappearance of the balloon waist. After balloon dilation, contrast medium from the pericardial space to subcutaneous tisse suggesting successful PBPWF. Single ballon method was employed in 4 patients and Dould balloon method in 2 patients. RESULT: We performed percutaneous balloon pericardial window formation in 6 patiemts with malignant pericardial effusion. We did percutaneous balloon pericardial window formation successfully in 5 patients and failed due to adhesion of parietal pericardium in 1 patient. One patient developed recurrent pericardial effusion with tamponade at a mean follow-up of 11.49.6 months(1.5-26 months). Conclusion: These results suggest that PBPWF is an alternative method less invasive than subxiphoid surgical windowing, espesially in critically ill patients with recurrent malignant pericardial effussion. It carries less risks and has more constant effect than repeated pericardiocentesis.
