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.

A household survey was conducted to compare the patterns of morbidity and medical care utilization between medical aid beneficiaries and medical insurance beneficiaries. The study population included 285 medical aid beneficiaries that were completely surveyed and 386 medical insurance beneficiaries selected by simple random sampling from a Dong (Township) in Taegu. Well-trained surveyors mainly interviewed housewives with a structured questionnaire. The morbidity rates of acute illness during the 15-day period, were 63 per 1,000 medical aid beneficiaries and 62 per 1,000 medical insurance beneficiaries. The rates for chronic illness were 123 per 1,000 medical beneficiaries and 73 per 1,000 medical insurance beneficiaries. The most common type of acute illness in medical aid and medical insurance beneficiaries was respiratory disease in medical aid beneficiaries, musculoskeletal disease was most common, but in medical insurance beneficiaries, gastrointestinal disease was most common. The mean duration of acute illness of medical aid beneficiaries was 3.8 days and that of medical insurance beneficiaries was 6.8 days. During the one year period, mean duration of medical aid beneficiaries chronic illnesses was 11.5 months which was almost twice as long compared to medical insurance beneficiaries. Pharmacy was most preferable facility among the acute illness patient in medical aid beneficiaries, but acute cases of medical insurance beneficiaries visited the clinic most commonly. Chronic cases of both groups visited the clinic most frequently. There were some findings suggesting that much unmet need existed among the medical aid beneficiaries. In acute cases, the average number of days of medical aid users utilized medical facilities was less than medical insurance users. On the other hand, the length of medical care utilization of chronic cases was reversed. Geographical accessibility was the most important factors in utilization of medical facilities. Almost half of the study population answered the questions about source of funds on medical security correctly. Most respondents considered that the objective of medical security was affordability. The chief complaint on hospital utilization was the complicated administrative procedures. These findings suggest that there were some problems in the medical aid system, especially in the referral system.

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.

Juvenile granulosa cell tumor is rare but one of the common congenital testicular neoplasms. Although histological features are typical of its ovarian counterpart, testicular juvenile granulosa cell tumor has a distinctly different clinical presentation. We report a case of juvenile granulosa cell tumor arising in the cryptochid testis of a 4-day-old newborn. A 6 5 5 cm sized multilocular cyst containing thick, mucinous fluid was found in the peritoneal cavity. The external surface of the cyst was smooth and the septae were relatively thin. The cyst consisted of numerous mucin-filled, cystic follicles lined by cells having vacuolated cytoplasm and round to oval dark nuclei without grooves. Cells resembling granulosa cells of an ovarian follicle were also observed in the intervening stroma forming irregular solid nests.

Reactions from stinging insects are significant to dermatologists because of the wide variety of clinical presentations from mild local reaction to severe anaphylactic reaction. Although ant sting commonly occurs, it has been rarely reported in the literatures. We experienced a unique case with allergic reactions by the ant of the Cremawgaster iw6w urai vagala, subfamily Myrmicinae, family Formicidea, order Hymenoptera that has not been previously reported.

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.

The clinical and pathological features of warty dyskeratoma are presented. Warty dyskeratoma is a rarely encountered, solitary, benign cutaneous tumor occurring most often on the head and neck and to our knowledge, no cases associated with cutaneous horn have been published in western literature. We experienced a case of warty dyskeratoma with a cutaneous horn occurring in a 70-year-old male, who had a 1.3 cm-sized and slowly growing nodule on his neck. A brief review of the literature, was made especially in relation to the pathological findings and histogenesis of warty dyskeratoma.

BACKGROUND: Valve replacement in children has many problems such as the durability of prosthetic valve, thomboembolism and hemorrhage. But recently, the necessity of valve replacement in children increased and the above problems were solved party. So the number of valve replacement in children increased progressively. RESULTS: Valve replacement in 47 children were done at Seooul National University Chidren's Hospital from March 1986 to July 1991. The patients were composed of 25 males and 33 females. 25 patients had congenital heart disease and 22 patients rheumatic heart disease. 45 patients received single valve repalcement, 2 patients double valve repalcement, and among all of them, 2 patients redo-replacement. The major valve lesion was mitral insufficiency and post-operative status in view of NYHA functinonal class was improved in most patients. The mechanical valves were applied to 45 patients and tissue valves to 2 patients. The indication of valve replacement were progressive increase in ventricular volume, major regurgitant fraction over grade III decrease in exercise tolerance and vegetation. The overall early mortality was 8.5% and late mortality 0%. There were post-operative complication rate of 30% and late complication rate 14%, and among the later, valve faliure was reported in 2 pantients and thromboembolism in 1 patient. The complication-free rate was 97.7% at post-operative 1 month, 91.3% at 12 months, 90% at 36 months and 60% at 48 months. 43 patients received anticoagulation and/or antiplatelet therapy, but there was no critical indication for this. CONCLUSION: These results suggest that cardiac valve replacement in children have been effective therapeutic modality even though various problems still remain, but we propose that sufficient long-term follow-up and clinical research be needed.
