Primary leiomyosarcomas are extremely rare. Its clinical configuration is a round to oval, more or less hemispherical elevation of the skin, but the appearance of these lesion is not distinctive so that the diagnosis is established by the histopathologic findings. Microscopically the cutaneous leiornyosarcomas consist of a poorly delineated proliferation of spindle shaped atypical myomatous cells arranged in interlacing fascicles which merge into collagenous stroma. We experienced a case of primary cutaneous leiornyosarcoma which developed as a hen egg sized tumor on the left shin in a 71-year-old woman and present this case with the review of literatures.

Although squamous cell carcinomas compose the majority of invasive cervical cancers, adenocarcinomas account for 10-20% of cervical cancers. Human papillomavirus (HPV) types 16 and 18 are strongly involved in the development of cervical neoplastic lesions squamous cell type. However, little is known about the association of HPV with adenocarcinoma because of its rarity, The p53 gene acts as a tumor suppressor and has been implicated in controlling cell cycle progression at the Gl-S transition, and absence or mutant of p53 gene is related to tumor progression. The present study was undertaken to identify clinical profiles, to characterize HPV infection status and p53 overexpression in the cervical adenocarcinoma and to investigate the prognostic significance of these findings. Thirty-six paraffin-embedded tumor tissues were obtained and patients clinical records were reviewed from tumor registry. Tissues were analyzed for the detection of HPV 16/1S by multiplex PCR and for the expression of p53 protein by immunohistochemical staining. Eighty-four percent of the cases were positive for HPV 16 and/or 18. HPV 16 positive rate was 36.1%, HPV 18 was 72.2%. The rate of double infection with HPV 16 and 18 was 25.0%. The p53 overexpression was detected in 11.1%. The overall 5 year-survival rate (YSR) was 72.2%. There were no significant difference in survival rate between HPV 18-positive and HPV 18-negative groups. The 5 YSR of the p53-positive group was 25.0% and that of p53-negative group was 78.1% (p=0.174). Inverse relationship between p53 overexpression and HPV DNA positivity was not found. In cervical adenocarcinoma, HPV type 18 was detected as the predo#minant type and may play a role in the carcinogenic process.

Postoperative brain damage is one of most serious complications of cardiopulmonary bypass (CPB). To prevent brain damage during CPB, adequate cerebral perfusion for cerebral oxygen demand should be maintained. This study monitored jugular venous oxyhemoglobin saturation (SjO₂), which reflects the overall balance of cerebral oxygen supply and demand, intermittently in 10 patients undergoing cardiac surgery. At the initiation of CPB, in spite of a significant decrease in mean arterial pressure, SjO₂ did not change, and it was stable during the hypothermic period of CPB. But a significan reduction in SjO₂ was observed during the rewarming period, and SjO₂ had an inverse linear correlation with esophageal temperature. Furthermore, the percent decrease of SjO₂ was related to rewarming speed. Therefore, therapeutic approaches for SjO₂ desaturation include slower rewarming, increasing cerebral blood flow, decreasing the cerebral metabolic rate for oxygen, increasing oxygen content, and increasing perfusion flow rate.

The results of hepatic portojejunostomy performed in 34 patients with biliary atresia between May 1989 and December 1997 were analyzed. These patients were divided into three groups based on age of surgery; group 1 (< or =60 days, n = 11); group 2 (61~90 days, n = 14), and group 3 (>90 days, n = 9). Jaundice was cleared in 22 cases (64.7%). There was no significant difference of jaundice-free rate according to the age at operation between group 1, 2, 3. After a mean follow-up period of 33.9 month (range 18days-105.7 month), there were eleven deaths from hepatic failure(6), esophageal varix bleeding even though anicteric(2), sepsis by cholangitis(1), heart failure(1) and renal failure(1). Two of group 1 and 3 had received liver transplantation. With follow-up of average 33.9 months (18days-106months, one follow-up loss), 5-year cumulative survival rate by Kaplan-Meier method was 65.9%. The 5-year survivals of group 1, 2, 3 were 63.6%, 77.9%, 41.4%. There was no significant difference of survival rates according to the age at operation between group 1, 2, 3. Moreover, two cases of group 3 survived more than 5 years. Therefore, hepatic portojejunostomy can be considered as a primary surgical modality for biliary atresia in a patient of 90 days or more. Early detection of esophageal varix and possible sclerotherapy is necessary for long term survival.

Vulva syringomas are rare in reviewing literature. In our case, a 29-year-old had multiple papular lesions involving both sides of the vulva. Microscopically the lesion showed dilated cystic sweat ducts some of which have small comma like tails resembling tadpoles. It is the purpose of this report to present a rare case of syringoma which was limited to the vulva without involvement of other sites.

Infantile fibrosarcoma is a rare malignant soft tissue tumor occurring especially in newborn and young children under 2 years. We experienced three cases of infantile fibrosarcoma presenting in the neonatal period. Case 1 presented with a multiseptated cystic mass on his left thigh at birth that was diagnosed as lymphangioma. After picibanil injection, we noted the size of the mass doubled and a solid lesion was prominent in the magnetic resonance image. Case 2 was found to have a reddish mass on his lower back mimicking hemangioma. Over 2 weeks, the mass grew rapidly with internal hemorrhaging. Case 3 was noted to have an encircling mass around the splenic flexure, which developed into congenital bowel obstruction. All of the tumors were resected completely, but microscopic resection margin was not clear in two patients. The two patients received adjuvant chemotherapy and all patients are well without evidence of recurrence.

Congenital afibrinogenemia is a rare disorder that refers to a congenital lack of production of fibrinogen, a key component of the hemostatic system. Bleeding manifestations of congenital afibrinogenemia vary in severity from mild to catastrophic. This is a case report of splenic rupture occurred in an eight-year-old boy with congenital afibrinogenemia. A conservative treatment was carried out with perfusion of cryoprecipitate and purified virally inactivated fibrinogen concentrates and splenectomy was avoided.

The chest radiographs and angiograms were retrospectively evaluated in 47 patients with pulmonary atresia (PA) and ventricular septal defect (VSD) to determine the characteristic findings of major aortopulmonary collateral arteries (MAPCSs) on the chest radiographs. Of 47 patients, 23 had MAPCAs and 24 had only PDA for blood supply of whole right and left lung. Chest radiographs enabled identification of 16 of 23 patients with MAPCAs. The most common finding of MAPCAs was inappropriately large peripheral pulmonary vasculature (n=16, 69.6%). The other findings were tortuosity of pulmonary vasculature (n=12, 52.2%), focal unevendistribution of pulmonary vasculature (n=12, 52.2%), and two descending pulmonary arteries (n=4, 17.4%). When chest radiographs showed two or more findings of MAPCAs, MAPCAs could be differentiated from PDA with statistical significance (p<0.005). It is concluded that chest radiographs may help to identify MAPCAs before angiography if two-dimensional echo ardiography suggests PA with VSD.
