A fine needle aspiration biopsy specimen of a retroperitoneal mass in a 26-year-old man who had had an orchiectomy for seminoma was submitted for cytologic evaluation. Cytologic features of the specimen included uniform neoplastic cells found singly or in groups of several cells intermingled with lymphocytes in a characteristic foamy, lacelike background. These cells varied from 10 to 20 m in diameter. The nuclei were round to ovoid with fine or reticular chromatin and one or more prominent nucleoli. The poorly defined cytoplasm stained pale-blue or blue with cytoplasmic vacuoles. The cytologic appearance was consistent with seminoma. Documented reports of the cytological appearance of seminoma are rare. The diagnosis of primary gonadal seminoma by fine needle aspiration biopsy is probably not indicated since the treatment of a primary gonadal tumor, regardless of its histogenesis, requires surgical resection. However, fine needle aspiration biopsy is extremely valuable in the diagnosis of extragonadal as well as metastic and recurrent seminoma.

3.Epidermoid Cyst after Groin Flap Mimicking Malignancy.
Journal of the Korean Society for Surgery of the Hand 2016;21(3):167-172
Epidermoid cyst is a benign tumor containing a layer composed by stratified squamous epithelium and filled with keratin. The epidermoid cyst after soft tissue damage such as bite, laceration could be caused by implantation of epidermal cells. There are reports of epidermoid cyst rarely occurred after surgical procedures such as bone graft or spine puncture. However, the report of epidermoid cyst associated with flap in the hand is very rare. We experienced such epidermoid cyst after the groin flap mimicking malignancy in the distal phalanx of the thumb. We found calcified mass with bony erosions in radiologic findings and heterotrophic signals and partial necrosis in magnetic resonance imaging that suggested malignancy. However, it was pathologically diagnosed as an epidermoid cyst. Therefore, we report the case and literature review.

BACKGROUND: Our aim was to make a comparative analysis of radiological and clinical outcomes of using either one or two interlocking distal screws on a Polarus intramedullary nail for the internal fixation of humeral shaft fractures. METHODS: From January 2008 to March 2014, we enrolled 26 patients with humeral shaft fractures who were operated on using intramedullary nails. The patients were divided into 2 groups according to how many interlocking distal screws were used to lock the Polarus nail: in group 1, a single interlocking distal screw was used in 12 patients; and in group 2, double interlocking distal screws, in 14 patients. We compared the degree of recovery of the displaced fracture fragments between the two groups. To compare the nonunion and shoulder function, we assessed each patient's modified American Shoulder and Elbow Surgerns (ASES) score. RESULTS: We found that 10 of 12 fractures achieved union in group 1, and 13 of 14 fractures, in group 2. We did not find a meaningful difference in the time to bone union between the two groups. The percentage of recovery of displaced fracture fragments until union was 66.9% for group 1 and 59.41% for group 2. At the final follow-up, we found that the scores for shoulder joint modified ASES was 78.7 for group 1 and 80.7 for group 2. CONCLUSIONS: Our results show that if locked appropriately, even a single screw on a Polarus nail can provide satisfactory radiological union and improved clinical outcome after intramedullary nailing of humeral shaft fractures.

5.Short-Term Results of Subpectoral Tenodesis of the Proximal Biceps Tendon Using by Interference Screw.
Journal of the Korean Shoulder and Elbow Society 2010;13(1):7-13
PURPOSE: Our purpose was to retrospectively analyze clinical results of subpectoral tenodesis of the proximal biceps tendon using an interference screw. MATERIALS AND METHODS: We reviewed 23 cases of patients receiving tenodesis of the proximal biceps tendon between January 2008 and January 2009 for whom we had follow-up data for at least 1 year. Twenty-three cases were operated on using subpectoral tenodesis; 16 of these cases had a rotator cuff tear. The results were judged using a visual analog scale (VAS), ASES, tenderness on the biceps groove, fixation failure and the degree of deformity (BAD). RESULTS: VAS and ASES scores were significantly improved in all patients by the time of the final observation. There were no significant complications or fixation failures. The patients without a tear of the rotator cuff had a better result than patients with a tear of the rotator cuff, but the difference between the two groups was not significant (p>0.05). CONCLUSION: In patients with pathology of the long head of the biceps brachii, benefits of subpectoral interference screw tenodesis include pain relief, maintenance of functional biceps, muscle strength, and cosmesis. Subpectoral biceps tenodesis using interference screw fixation appears to be a promising, reproducible, reliable technique for addressing anterior shoulder pain related to pathology of the long head of the biceps brachii.

PURPOSE: The effects of desensitizing agent are often for a short duration. One of the reasons is believed to be wear of desensitizing agent by tooth brushing. To reduce the wear and make the duration longer, dental bonding resin was applied and the changes of dentin permeability after toothbrushing were measured. MATERIALS AND METHODS: Extracted teeth free from caries were chosen. Coronal dentin discs with thickness of 1 mm were prepared. Using the split chamber device developed by Pashely, hydraulic conductance and scanning electron microscope images (SEM) were compared and contrasted before and immediately after the application of desensitizing agent and bonding resin and then after equivalent tooth brushing of 1 week, 2 weeks, and 6 weeks. Four commercially available desensitizing agents were used in this study; they were All-Bond 2, Seal & Protect, Gluma, and MS Coat. And Dentin/Enamel Bonding resin (Bisco Inc.) was used. The results of this study are as follows. RESULTS: On all specimens, the hydraulic conductance decreased after the application of tooth desensitizing agent and bonding resin. Compared with the specimens treated only with desensitizer, the specimens treated with All-Bond 2, Gluma, MS Coat and plus D/E bonding resin had a little increase in hydraulic conductance after 1, 2 and 6-week tooth brushing. In case of Seal & Protect, the specimens showed the same result only after 6-week tooth brushing. On examination of SEM, the dentinal tubule diameter had decreased after treatment of desensitizing agents and bonding resin. And the specimens treated with All-Bond2, Seal&Protect, Gluma, MS Coat and plus D/E bonding resin had an significant decrease in diameter of dentinal tubule after 6-week tooth brushing. CONCLUSION: According to the results of this study, it is effective to use bonding resin after application of desensitizer in reducing the wear by tooth brushing and making the duration longer. In this study, just 6-week tooth brushing was performed, and it is not enough to regard it as a long-term data. So further study is needed and more perfect method for treating dentin hypersensitivity should be developed.

PURPOSE:
Nipple-sparing mastectomy (NSM) has become increasingly popular due to improved cosmesis without compromising oncologic safety. Radial and inframammary incisions are usually used to achieve NSM, with periareolar incisions usually being avoided because of the risk to nipple-areola complex viability. In an attempt to maximize esthetic effects, we performed NSM through periareolar incision with immediate reconstruction. We report our initial experience.
METHODS:
This case series consisted of all consecutive patients (n = 34) who underwent NSM through a periareolar incision in our institution between August 2017 and December 2018. All patients underwent NSM through periareolar incision followed by immediate reconstruction with an implant or deep inferior epigastric perforator flap. Patient demographics, tumor and treatment characteristics, and short-term postoperative outcomes were reviewed.
RESULTS:
The mean patient age was 46.74 ± 6.69 years (range, 38–62 years), and the mean operation time was 96.68 ± 28.00 minutes. Indications included in situ cancer in 12 cases and invasive cancer in 22 cases. There was 1 major complication (postoperative hematoma) requiring operative reintervention. No other complications including fistula, implant exposure, or reconstruction failure was observed. At the time of writing, no case of local recurrence has been observed.
CONCLUSION
Our initial report shows that NSM with immediate reconstruction may successfully be performed through periareolar incision. This method maximizes esthetic effects and may be an appropriate surgical option for NSM.

The lung and stomach are very unusual sites for teratoma. The histologic findings of intrapulmonary and gastric teratomas are not different from those arising in usual sites, such as the ovary or testis. However, preoperative diagnosis is sometimes difficult to make partly because of unusual location. We report here two cases of teratoma, one intrapulmonary teratoma and the other gastric. The intrapulmonary teratoma in our study had an endobronchial tumor growth, which rules out mediastinal teratoma. Meanwhile gastric teratomas usually present as a submucosal tumor and most cases are reported in infancy and childhood. Gastric teratoma in this study occurred in a 27-year-old man. To the best of our knowledge, this case of intrapulmonary teratoma is the eighth and the gastric teratoma is the first to be reported in Korea.

A 52-year-old woman with a history of general weakness, fatigue, weight loss, elevated serum levels of liver transaminase enzyme for three months underwent an F-18 FDG PET/CT scan to evaluate a cause of the hepatosplenomegaly found on abdominal ultrasonography. Initial PET/CT revealed markedly enlarged liver and spleen with intense FDG uptake. Otherwise, there were no areas of abnormal FDG uptake in whole body image. Histological evaluation by a hepatic needle biopsy demonstrated diffuse large B cell type lymphoma and final diagnosis for this patient was hepatosplenic B-cell lymphoma. She received five cycles of CHOP chemotherapy, and second PET/CT scan was followed after then. Follow-up PET-CT revealed normal sized liver with disappearance of abnormal FDG uptake. Hepatosplenic B-cell lymphoma is relatively rare and mostly presents as single or multiple nodules.1,2 Diffuse type hepatosplenic lymphoma is extremely rare and poorly recognized entity.3 The diagnosis is very difficult and complicated by the presence of misleading symptoms.4 In this rare hepatosplenic B-cell lymphoma case, F-18 FDG PET/CT scan provided a initial diagnostic clue of hepatosplenic lymphoma and an accurate chemotherapy response.
