Ki-1 monoclonal antibody is a well known marker for Reed-Sternberg cells in Hodgkin's disease, but also occasionally reacts with activated lymphoid cells of either benign or malignant nature. Recently, Ki-1 antibody positive Non-Hodgkin's lymphoma, usually of large cell and/or polymorphous type, has been reported in the lymph nodes, skin, soft tissue, and stomach, but not in the bone. We report a case of multifocal primary bone lymphoma in a seven-year old body involving the left shoulder and right frontal bone, which proved to be a large cell, polymorphous lymphoma, helper T-cell type expressing Ki-1 antigen.

PURPOSE: Laparoscopy-assisted distal gastrectomy (LADG) has become a viable alternative treatment for patients suffering with early gastric cancer. Surgeons have long thought that obesity might increase the rate of intraoperative or postoperative complications. This study was performed to evaluate the impact of obesity, according to the learning curve, in patients who underwent laparoscopy assisted distal gastrectomy for gastric cancer. METHODS: We retrospectively reviewed 100 patients who had undergone LADG for gastric cancer between September 2004 and May 2007 at Keimyung University Dongsan Medical Center. We measured the degree of obesity by using the body mass index (BMI: kg/m(2)), and we compared the surgical outcomes between the low BMI group (BMI < 25 kg/m(2), n=72) and the high BMI group (BMI >25 kg/m(2), n=28). We further subdivided the patients into the surgeons' number of cumulative LADG cases, the early learning curve group (from the first patient to the 50th patient) and the late learning curve group (from the 51th patient to the 100th patient). We analyzed them in terms of the operation time, the amount of intraoperative bleeding, the number of retrieved lymph nodes, the rate of operative morbidity and the length of the postoperative hospital stay. RESULTS: There no significant differences between the high and low BMI groups in terms of the patients' clinicopathologic characteristics and surgical outcomes, but there was a statistically significant difference in the operation times between the high BMI (303.3 min) and low BMI groups (269.3 min, P=0.029). The postoperative morbidity was not different between the high BMI (25%) and low BMI groups (12.5%, P=0.12). However, when we subdivided the patients by the learning curve, there was a statistically significant difference for the operation time (360 vs 297 minutes, respectively), postoperative morbidity (41.7 vs 10.5%, respectively) and the postoperative hospital stay (15.5 vs 8.6 day, respectively) between the high BMI and low BMI groups at the early learning curve period. Especially for male patients, the early learning curve period showed significant differences in the operation time, the postoperative morbidity and the postoperative hospital stay between the high BMI and low BMI groups, but in case of the female patients, there was no difference in postoperative morbidity and the length of the postoperative hospital stay. At the late learning curve period, there was no difference according to gender and obesity. CONCLUSION: Obesity itself does not increase operative morbidity when performing LADG in patients with gastric cancer. However, at a surgeon's initial period of performing LADG, a careful approach seems to be required for male obese patients.

A 21-year-old man with diabetic ketoacidosis (DKA) displayed short and clubbed fingers and marked eyebrow, which are typical of Hajdu-Cheney Syndrome (HCS). Laboratory findings confirmed type 1 diabetes mellitus (DM). After conservative care with hydration and insulin supply, metabolic impairment was improved. Examinations of bone and metabolism revealed osteoporosis and craniofacial abnormalities. The mutation (c.6443T>G) of the NOTCH2 gene was found. The patient was diagnosed with HCS and DM. There may be a relationship between HCS and DM, with development of pancreatic symptoms related to the NOTCH2 gene mutation.

PURPOSE: To report a patient with Leber's idiopathic stellate neuroretinitis accompanying peripapillary sensory retinal detachment detected with optical coherence tomography. CASE SUMMARY: A 26-year-old woman complained of visual disturbance in her right eye for several months. Her best corrected visual acuity was 0.5 in the right eye and 0.9 in the left eye. A relative afferent papillary defect was present in the right eye. Severe disc swelling with retinal hemorrhage and stellate macular exudates were observed in the right eye. Fluorescein angiography revealed optic disc leakage. There appeared to be no leakage from the other retinal vessels or from the retinal pigment epithelium. OCT revealed outer nuclear-plexiform layer fluid accumulation in the papillomacular region. Eight weeks after steroid treatment, the best corrected visual acuity in the right eye had improved to 0.7, and the optic disc edema had improved. The OCT showed that the fluid in the outer nuclear-plexiform layer space had largely been absorbed.

PURPOSE: To investigate the results of 23-gauge sutureless vitrectomy and preoperative bevacizumab in diabetic retinopathy cases. METHODS: A total of 212 eyes received pars plana vitrectomy by a single surgeon for proliferative diabetic retinopathy and were followed up for at least 6 months. The change of visual acuity and operative complications among the 20-gauge vitrectomy (group I, 86 eyes), 23-gauge vitrectomy (group II, 30 eyes), and 23-gauge vitrectomy with preoperative intravitreal bevacizumab (IVB) injection (group III, 96 eyes) were retrospectively analyzed. RESULTS: One month postoperatively, visual improvement was better in groups II and III than in group I. Three months postoperatively, visual improvement was better in group III than in groups I and II. Six months postoperatively, visual improvement in group III was better than in group I, but there was no significant difference between group II and III. Intraoperative retinal breaks and postoperative vitreous hemorrhage were less common in group III than in groups I and II. CONCLUSIONS: In patients with proliferative diabetic retinopathy, 23-gauge sutureless vitrectomy showed faster visual recovery compared with 20-gauge vitrectomy, and vitrectomy with preoperative bevacizumab had less intraoperative and postoperative complications than vitrectomy without preoperative bevacizumab.

Wilms' tumor is one of the most common abdominal neoplasms in the pediatric age group. The incidence of bilateral involvement is generally estimated to be 5 to 10 per cent. In the past, synchronous bilateral Wilms' tumor was almost always atal but multidisciplinary treatments have resulted in clearly improved prognosis. When the clinical characteristics of patient with bilateral tumors were compared with those of patients with unilateral tumors, several features became evident. Herein the authors report a case of a 7 month old infant with synchronous bilateral Wilms' tumor with congenital anomalies.

PURPOSE: Lymph node metastasis is an important prognostic factor in patients with early gastric cancer. Therefore, we analyzed the predictive factors for lymph node metastasis in submucosal gastric cancer and explored the feasibility of minimally invasive surgery. METHODS: The clinicopathological features of 317 patients with submucosal gastric cancer, who underwent radical gastrectomy with lymph node dissection at Department of Surgery, Keimyung University School of Medicine from January 2003 to December 2007, were examined retrospectively. The lesions were divided into 3 layers according to the depth of submucosal invasion of the cancer cell (SM1, SM2, and SM3). We analyzed the clinicopathological variables regarding lymph node metastasis. RESULTS: Of the 317 patients, 74 patients (23.3%) had lymph node metastasis. Tumor size, histological type, Lauren classification, depth of invasion, lymphatic invasion, vascular invasion, and perineural invasion showed a positive correlation with lymph node metastasis by univariate analysis. In multivariate analysis, tumor size (> or =4 cm vs <2 cm, P=0.034 and 2~4 cm vs <2 cm, P=0.043), histological type (P=0.013), and lymphatic invasion (P=0.000) were significantly correlated with lymph node metastasis. CONCLUSION: Tumor size, histological type, and lymphatic invasion were independent risk factors for lymph node metastasis in submucosal gastric cancer. Minimally invasive surgery, such as endoscopic submucosal dissection may be applied to submucosal gastric cancer with a tumor size less than 2 cm, differentiated histological type, and no lymphatic invasion.

BACKGROUND AND OBJECTIVES: The purpose of the present study was to compare the results of V-shaped and modified facelift incisions for parotidectomy. SUBJECTS AND METHOD: Ninety parotidectomy patients who underwent V-shaped and modified facelift incisions from 2014 to 2018 were enrolled in this study. Patient characteristics, tumor profiles, surgical outcomes, postoperative complications, and cosmetic results were assessed for the V-shaped (n=20) and modified facelift (n=70) incision groups. RESULTS: The tumor size was significantly larger in the modified facelift incision group than in the V-shaped incision group (2.6 cm vs. 1.9 cm, p < 0.001). There were no significant differences between the two groups regarding other baseline tumor characteristics, operating time, and postoperative complications. Although the results of Vancouver Scar Scale was similar in both groups, the V-shaped incision group showed higher subjective scar satisfaction scores than the modified facelift incision group (9.3 vs. 8.6, p=0.001). CONCLUSION: The results suggest that the V-shaped incision is feasible and can provide better subjective scar satisfaction in selected parotidectomy patients without increased complications.
