Gastric cavernous hemangioma is a relatively rare benign gastric disease. Gastric hemangiomas are most commonly encountered in adulthood, although they can occur in any age group. While surgical resection is the curative treatment, endoscopic resection can be performed for treatment of selected cases. The patient was a 53-year-old male who was referred for evaluation of incidentally detected gastric subepithelial tumor with dense vascularity and oozing on the apex of the lesion. An EUS revealed a homogenously hypoechoic mass confined to the submucosal layer that showed no continuity with adjacent vessels, and there was no regional lymphadenopathy. Endoscopic submucosal dissection was successfully performed with en bloc resection. The final diagnosis was benign cavernous hemangioma of the stomach.

PURPOSE: The purpose of this study is to evaluate the influence of intracapsular fracture lines of the mandibular condyle on the anatomical and functional recovery after non-surgical closed treatment. METHODS: Clinical and radiological follow-up of 124 patients with intracapsular fractures of the mandibular condyle was performed after closed treatment between 2005 and 2012. The intracapsular fractures were classified into three categories: type A (medial condylar pole fracture), type B (lateral condylar pole fracture with loss of vertical height) and type M (multiple fragments or comminuted fracture). RESULTS: By radiological finding, fracture types B and M lost up to 24% vertical height of the mandibular condyle compared to the height on the opposite side. In Type M, moderate to severe dysfunction was observed in 33% of the cases. Bilateral fractures were significantly associated with the risk of temporomandibular joint (TMJ) dysfunction in fracture types A and B. Bilateral fracture and TMJ dysfunction were not statistically significantly associated in type M fractures. CONCLUSION: Most of the mandibular intracapsular condylar fractures recovered acceptably after conservative non-surgical treatment with functional rehabilitation, even with some anatomical shortening of the condylar height. The poor functional recovery encountered in type M fractures, especially in cases with additional fracture sites and bilateral fractures, points up the limitation of closed treatment in such cases.

PURPOSE: Maxillofacial fractures are rapidly increasing from car accidents, industrial accidents, teenaged criminal activity, and sports injuries. Accurate assessment, appropriate diagnosis, and preparing individual treatment plans are necessary to reduce surgical complications. We investigated recent trends of facial bone fracture by period, cause, and type, with the objective of reducing surgical complications. METHODS: To investigate time trends of maxillofacial fractures, we reviewed medical records from 2,196 patients with maxillofacial fractures in 1981~1987 (Group A), 1995~1999 (Group B), and 2008~2012 (Group C). We analyzed each group, comparing the number of patients, sex ratio, age, fracture site, and etiology. RESULTS: The number of patients in each period was 418, 516, and 1,262 in Groups A to C. Of note is the increase in the number of patients from Group A to C. The sex ratios were 5.6:1, 3.5:1, and 3.8:1 in Groups A, B, and C. The most affected age group for fracture is 20~29 in all three groups. Traffic accidents are the most common cause in Groups A and B, while there were somewhat different causes of fracture in Group C. Sports-induced facial trauma was twice as high in Group C compared with Group A and B. Mandible fracture accounts for a large portion of facial bone fractures overall. CONCLUSION: We observed an increase in facial bone fracture patients at Kyungpook National University Dental Hospital over the years. Although facial injury caused by traffic accidents was still a major cause of facial bone fracture in all periods, the percentage decreased. In recent years, isolated mandible fracture increased but mandible and mid-facial complex fracture decreased, possibly because of a reduction in traffic accidents.

OBJECTIVES: The purpose of this study was to analyze the survival rate of reconstruction plates that were used to correct mandibular discontinuity defects. MATERIALS AND METHODS: We analyzed clinical and radiological data of 36 patients. Only discontinuous mandibular defect cases were included in the study. Reconstruction plate survival rate was analyzed according to age, gender, location of defect, defect size, and whether the patient underwent a bone graft procedure, coronoidectomy, and/or postoperative radiation therapy (RT). RESULTS: Plate-related complications developed in 8 patients, 7 of which underwent plate removal. No significant differences were found in plate survival rate according to age, gender, location of defect, defect size, or whether a bone graft procedure was performed. However, there were differences in the plate survival rate that depended on whether the patient underwent coronoidectomy or postoperative RT. In the early stages (9.25+/-5.10 months), plate fracture was the most common complication, but in the later stages (35.75+/-17.00 months), screw loosening was the most common complication. CONCLUSION: It is important to establish the time-related risk of complications such as plate fracture or screw loosening. Coronoidectomy should be considered in most cases to prevent complications. Postoperative RT can affect the survival rate and hazard rate after a reconstruction plate is fitted.

PURPOSE: Breast cancer treatment has progressed significantly over the past 20 years. However, knowledge regarding male breast cancer (MBC) is sparse because of its rarity. This study is an investigation of the clinicopathologic features, treatments, and clinical outcomes of MBC. MATERIALS AND METHODS: Clinical records of 59 MBC patients diagnosed during 1995-2014 from seven institutions in Korea were reviewed retrospectively. RESULTS: Over a 20-year period, MBC patients accounted for 0.98% among total breast cancer patients, and increased every 5 years. The median age of MBC patientswas 66 years (range, 24 to 87 years). Forty-three patients (73%) complained of a palpable breast mass initially. The median symptom duration was 5 months (range, 1 to 36 months). Mastectomy was performed in 96% of the patients. The most frequent histology was infiltrating ductal carcinoma (75%). Ninety-one percent of tumors (38/43) were estrogen receptor–positive, and 28% (11/40) showed epidermal growth factor receptor 2 (HER-2) overexpression. After curative surgery, 42% of patients (19/45) received adjuvant chemotherapy; 77% (27/35) received hormone therapy. Five out of ten patients with HER-2 overexpressing tumors did not receive adjuvant anti–HER-2 therapy, while two out of four patients with HER-2 overexpressing tumors received palliative trastuzumab for recurrent and metastatic disease. Letrozole was used for one patient in the palliative setting. The median overall survival durations were 7.2 years (range, 0.6 to 17.0 years) in patients with localized disease and 2.9 years (range, 0.6 to 4.3 years) in those with recurrent or metastatic disease. CONCLUSION: Anti–HER-2 and hormonal therapy, except tamoxifen, have been underutilized in Korean MBC patients compared to female breast cancer patients. With the development of precision medicine, active treatment with targeted agents should be applied. Further investigation of the unique pathobiology of MBC is clinically warranted.

BACKGROUND: Cystic neoplasms of the pancreas are being recognized with increased frequency. In 1993, a report on 123 cases of cystic neoplasms of the pancreas diagnosed over a period of 32 years was published in Korea. Many changes on the concept of cystic neoplasms of the pancreas have been made, including classification and diagnostic criteria. The present study was conducted wherein a new survey on cystic neoplasms of the pancreas in Korea. METHODS: Cystic neoplasms of the pancreas diagnosed over a period of 12 years, from 1993 to 2004 in 25 university hospitals throughout Korea were collected. They were classified according to the World Health Organization classification of cystic neoplasms of the pancreas. RESULTS: A total of 1264 cases of cystic neoplasms of the pancreas were diagnosed. The diagnoses and frequencies are as follows: intraductal papillary mucinous neoplasm, 499 (39.5%); mucinous cystic neoplasm, 318 (25.2%); serous cystic neoplasm, 232 (18.4%); solid pseudopapillary neoplasm, 192 (15.2%); cystic endocrine neoplasm, 11 (0.8%); lymphoepithelial cyst, 8 (0.6%); acinar cell neoplasm, 3 (0.2%); mature teratoma, 1 (0.1%). Increase in the annual number of diagnoses was evident. In intraductal papillary mucinous neoplasm and mucinous cystic neoplasm, a significant increase in mean age was seen in patients with malignant neoplasms. CONCLUSIONS: Cystic neoplasms of the pancreas are diagnosed with increasing frequency in Korea, the most common being intraductal papillary mucinous neoplasm of the pancreas. In intraductal papillary mucinous neoplasm and mucinous cystic neoplasm, the grade of dysplasia increased with mean age, suggesting an adenoma-carcinoma sequence.
