Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors. However, it remains difficult to differentiate cystadenoma from cystadenocarcinoma for multiseptated cystic hepatic lesions with papillary projection on computed tomography (CT) and magnetic resonance imaging (MRI). Here we report the case of a 47-year-old woman with several months of postprandial discomfort and abdominal fullness. CT and MRI revealed multiseptated cystic lesions with papillary excrescences. A left hemihepatectomy was performed. Histology showed a benign mucinous cystic tumor with ovarian-like stroma.

We have experienced a case of neurofibromatosis with unusual giant pigmentation, which presents itself as a 28 cm x 40 cm sized, serrated bordered light brownish patch speckled with small dark hyperpigmented macules on his back. Histopathologic examinations of light brown patch and speckles showed only an increase in basal melanin pigmentation.

The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study, the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large gonial angle in orthognathic surgical cases with skeletal Class Iii malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was sgrall in male.

The purpose of this study was to evaluate the histologic difference that occured after trichloroacetic acid(TCA) chemical peel in an animal model that was pretreated with Tretinoin alone or Tretinoin-based combined pretreatment kit. Eight Hartley white guinea pigs were used in our study. The dorsal skin of the guinea pigs was divided into six equal squares(2x2 cm). Upper two areas of these six were not pretreated, middle two areas were pretreated for 4 weeks with Tretinoin alone and lower two areas were pretreated for 4 weeks with Tretinoin-based combined kit. Each guinea pig underwent chemical peel with 50% TCA. The wounded areas were biopsied at post-peeling 3 weeks and 6 weeks. The histology revealed that those animals pretreated with combined kit healed quicker than the animals pretreated with Tretinoin alone. This study implies that if patients are treated with Tretinoin-based-combined pretreatment kit before undergoing chemical peel, the pretreatment time will be shortened.

PURPOSE: High frequency oscillatory ventilation (HFOV) is used to support infants with severe respiratory failure unresponsive to conventional ventilation (CV). We reviewed chest radiographs before and after HFOV with clinical correlation in infants with respiratory distress syndrome (RDS). METHODS: Eighteen very low birth weight infants with RDS who had HFOV were included in this study. All patients were diagnosed as having RDS clinically and radiologically. Mean gestational age of infants was 27 weeks (range : 24-31 weeks). The mean duration of HFOV was 3 days (range : 14 hours-9 days). The chest radiographs of these infants within 3 hours before and after application of HFOV were retrospectively reviewed. Radiological findings based on aeration and parenchymal densities were classified into improved, no change, and progressed. Medical records were reviewed for FiO2 levels, clinical outcomes, complications, and causes of death. RESULTS: In 15 of 18 infants, aeration and parenchymal densities were improved and FiO2 levels were also improved after HFOV. Four of these 15 infants who showed improvement of radiological findings developed pneumothorax, sepsis, pulmonary or intestinal bleeding, and subsequently died. In remaining 3 infants in whom chest radiographs after HFOV showed no interval change or progression, oxygenation was also worsened and all died. CONCLUSION: Chest radiographs of HFOV-treated, very low birth weight infants showed improvement of aeration and parenchymal densities in most cases. Clinical outcome was good in infants who showed improvement on chest radiographs compared to those of progression group as far as there was no associated complication. Knowledge of radiological changes after HFOV will help in interpretation of chest radiographs in those HFOV-treated infants.

We report the implantation of a balloon-expandable intravascular stent at proximal left anterior decending artery in a patients suffered from Canakian functional class III angina for 8 years. The patient received 3 times percutaneous transluminal coronary angioplasty at proximal left anterior descending and circumflex artery without benefits. Repeated angiography revealed restenosis at proximal left anterior descending artery. Atherectomy was tried with transluminal extraction catheter(TEC) with luminal dissection and coronary bypass graft followed. occluded vein grafts were defined by follow-up angiography and chest pain recurred. No residual stenosis or thrombosis was documented in 24 hour follow-up angiography and the patient was discharged without symptom at 10 days after stenting.

OBJECTIVES: Breast conserving surgery (BCS) for early breast cancer is now an accepted treatment, but there are controversies about its comparability with mastectomy. Thus, we investigated the survival outcomes who underwent BCS and modified radical mastectomy (MRM). METHODS: In this retrospective review, we analyzed the survival outcomes of 618 patients with early breast cancer who underwent two different surgery from January 2002 to December 2009. Postoperative pathologic difference, disease free survival period, overall survival period, recurrence pattern, recurrent rate and site were compared. In addition, preoperative patients data are also collected. RESULTS: Disease free survival period of MRM and BCS was 108.46 months and 80.82 months, respectively (P < 0.01). However, there was no significant correlation between overall survival period and operative methods (P = 0.67). In addition, recurrence pattern (P = 0.21), recurrent rate (P = 0.36) and site (P = 0.45, P = 0.09) were not associated with operative method. CONCLUSIONS: In this study, we can suggest that early breast cancer patients could improve their disease free survival if they underwent MRM. So, when we operate high risk breast cancer patients, MRM could be considered for their disease free life. Further studies may be required to establish appropriate strategy of surgery for early breast cancer.

A 72-year-old woman developed pruritic erythematous patches on sun-exposed areas for 2 months following treatment with hydrochlorothiazide (Dichlozid) for hypertension. A phototest revealed a decreased minimal erythemal dose to UVA (MED(UVA)=2 J/cm²). A photopatch test with 0.5%, 1%, and 5% hydrochlorothiazide ointment revealed no response. Two weeks after discontinuation of hydrochlorothiazide, the skin lesions improved with complete loss of photosensitivity without any therapy. At that time, an oral provocation phototest with hydrochlorothiazide was performed and it showed a decreased MED to UVA (MED(UVA)=2 J/cm²).
