Leiomyosarcoma arising in the skin is rare tumor, and diagnosis usually is made microscopically. After local excision, these lesions recur in large proportion of pat ients. The authors herein report a 53-year-old male with leiomyosarcoma appeared in the skin of the right forearm and presenting as a dark reddish colored, 5*6cm in diameter, superficial ulcerated single firm nodule with intermittent pain. Histopathological examination showed poorly circumscribed tumor consisting of interlacing bundles of spindle shaped smooth muscle cells in the middle and lower parts of the dermis. The nuclei were hyperchromatic, large, vacuolated, and irregular in shape. Electron microscopic findings revealed cytoplasmic organelles such as rough endoplasmic reticulum and mitochondria of malignant smooth muscle cells in the paranuclear area, Characteristic subsarcoelmmal caveolae and dense plaque were noted and myofilaments were distributed in the peripheral cytoplasm. The tumor did not recur in 10 months' follow-up.

OBJECTIVE: The purpose of this study was to compare the right and left differences of frontal ramal inclination in chin-deviated individuals. METHODS: Thirty adult patients with clinically apparent chin deviation were selected as the chin-deviated group, and 30 adult patients with symmetric faces were selected as the control group. On the posteroanterior cephalograms, the frontal ramal inclination was measured, and the right and left differences were compared and analyzed. RESULTS: While the control group did not show right and left differences of frontal ramal inclinations, the chin-deviated individuals showed right and left differences of frontal ramal inclination. In chin-deviated individuals, the frontal ramal inclinations of the non-deviated side were statistically greater than those of the deviated side. The right and left differences of frontal ramal inclinations, with menton deviation and the right and left differences of maxillary heights showed statistically significant correlation. CONCLUSION: We conclude that the frontal ramal inclinations should be considered in the diagnosis of facial asymmetry.

This is a case report of the congenital ileal atresia with disuse microcolon. The patient was a 3 day-old male newborn infant who was admitted in department of pediatrics Soon Chun Hyang Hospital with complaints of persistant vomitings, no meconium passage, and jaundice from a few hours after birth. The diagnosis was established by characteristic clinical features and barium enuma and finally confirmed by operationl. The operative findings showed that entire colon showed very narrow lumen and was associated with malrotation of the cecum, volvulus of midgut, multiple bands formation, and atresia of ileum with marked dilated proximal small bowel. It is considered that this microcolon was originated from non-use of the colon due to atreisa of the ileum. Resection of the obstructed ileum with multiple bandlysis and finally ileo-ileal end to end anastomosis were done. Microscopic findings showed that sections of cord like mass revealed marked narrowing of mucosal lumen with collections of mucus and necrotic cell debris and lack of mucosa. He was discharged 50 days after operation with favorable condition and normal finding of follow-up barium enema. A brief review of related literature was also presented.

Enlargement is an inherent property of X-rays which occurs when straight lines diverge from small a focal spot. The purpose of the present study was to evaluate the validity of the correction of gonial angle width enlarged on frontal cephalogram, using frontal and lateral cephalograms taken orthogonally from each other. In 40 adult individuals, frontal and lateral cephalograms were taken at a 90 degrees angle using the Head Posture Aligner. The angle width was measured on the frontal cephalogram and subsequently, the corrected angle width was calculated using the magnification rate of two cephalograms. Measured and corrected angle widths were compared with the measurement from the 3D CT image. The measurement on the frontal cephalogram showed a 9.10 mm of enlargement on average, ranging from 7.92 to 11.31 mm. Corrected angle width measurement showed a 0.14 mm difference with the 3D CT image measurement, which was not statistically significant. The results of the study indicate that actual angle width can be approached through calculation using frontal and lateral cephalograms taken orthogonally with the help of the Head Posture Aligner. The study also showed that the magnitude of correction error did not show a significant correlation with the amount of menton deviation, and it suggests that the present correction method is valid even in individuals with severe facial asymmetry.

PURPOSE: Virtual colonoscopy is the most recently developed tool for detecting colorectal cancers and polyps, but its effectiveness is limited. In our study, we compared the result of preoperative virtual colonoscopy to result of preoperative and postoperative colonoscopy. We evaluated also the accuracy of preoperative virtual colonoscopy in patients who had obstructive colorectal cancer that did not allow passage of a colonoscope. METHODS: A total of 164 patients who had undergone preoperative virtual colonoscopy and curative surgery after the diagnosis of a colorectal adenocarcinoma between November 2008 and August 2013 were pooled. We compared the result of conventional colonoscopy with that of virtual colonoscopy in the nonobstructive group and the results of preoperative virtual colonoscopy with that of postoperative colonoscopy performed at 6 months after surgery in the obstructive group. RESULTS: Of the 164 patients, 108 were male and 56 were female patients. The mean age was 62.7 years. The average sensitivity, specificity, and accuracy of virtual colonoscopy for all patients were 31.0%, 67.2%, and 43.8%, respectively. In the nonobstructive group, the average sensitivity, specificity, and accuracy were 36.6%, 66.2%, and 48.0%, respectively, whereas in the obstructive group, they were 2%, 72.4%, and 25.4%. Synchronous cancer was detected via virtual colonoscopy in 4 of the 164 patients. CONCLUSION: Virtual colonoscopy may not be an effective method for the detection of proximal colon polyps, but it can be helpful in determining the therapeutic plan when its results are correlated with the results of other studies.

The management of the third molar tooth in mandibular angle fracture is still controversial. Retrospective analysis of 197 cases of mandibular angle fractures associated with third molar tooth was undertaken. Selective prophylactic extraction of the third molar teeth were undertaken in 66 cases. The third molar teeth were retained in 131 fractures. The indication of extraction of the third molar teeth in mandibular angle fracture were as follows: 1) interfering with reduction of the fracture; 2) excessive mobility; 3) exposure of tooth root due to distraction of the fracture; 4) fractured teeth; 5) severely carious tooth 6) infected supporting structure. There were no significant differences between the complication rate in the "tooth removed" group and "tooth retained" group. Complications were minimal. Therefore proper management of the third molar tooth in mandibular angle fracture will minimize complication.

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H₂ blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.

PURPOSE: To evaluate the ultrasonographic features of nonlactiferous breast abscess. MATERIALS AND METHODS: We retrospectively reviewed ultrasonograms of 21 cases with surgically and clinically proved nonlactiferous breast abscess. The cases included 17 cases of acute or chronic inflammation and 4 cases of tuberculosis. RESULTS: Location of the lesion was subareolar in 15 cases and peripheral in 6. Mean anteroposterior/transverse diameter ratio was 0.49. Internal echogenicitiy of the lesion was variable, with heterogeneous mixed-echoic echotexture in 18 cases and homogeneous hypoechoic in 3. Margin of the lesion was irregular in 18 cases(85.7%) and posterior sonic enhancement was observed in 17 cases(81%). There were also noted obliteration of adjacent superficial fascia, localized skin thickening, and sinus tract or ductal ectasia in 19(90.5%), 9 (42.9%), and 9(42.9%) cases respectively. CONCLUSION: Major ultrasonographic findings of nonlactiferous breast abscess was subareolar located, variable shaped mass with posterior enhancement. Additional findings were fistular formation, loss of superficial fascia, and axillary lymphadenopathy.

BACKGROUND: Magnesium sulfate (MgSO4) is a drug of choice for women with preeclampsia, with evidence that it reduces progression to eclampsia and maternal mortality. However, no previous studies have been conducted on the effect of magnesium sulfate on labor. This retrospective study investigated the effect of magnesium sulfate on the labor duration and the neonatal outcomes in parturients with preeclampsia. METHODS: We reviewed the medical records of 209 women who delivered vaginally with the diagnosis of preeclampsia from January 1, 2003 to June 30, 2013. They were divided into two groups, primipara (Primi group) and multipara (Multi group). Then, each group was subclassified as MgSO4-treated (Mg group) and MgSO4-untreated group (Cont group) again. Collected data included the duration of each stage of labor and neonatal outcomes. RESULTS: The duration of the 1st stage of labor was significantly longer in the Multi-Mg group, compared with the Multi-Cont group (138 +/- 149 min vs. 88 +/- 92 min, P = 0.025). However, the total labor durations were comparable between the two groups. Primi group had no difference in durations of any stage of labor and the total duration. Neonates showed worse outcomes (lower birth weight, lower Apgar, higher NICU admission rate) in the Primi-Mg group than the Primi-Cont group. CONCLUSIONS: Although preeclamptic multiparous parturients treated with MgSO4 showed longer 1st stage of labor than those untreated with MgSO4, the total labor durations were comparable between the groups.
