A teratoma is the most common benign germ cell tumor that develops in the mediastinum. Patients with a mediastinal teratoma are usually asymptomatic. However, a spontaneous rupture of a mediastinal teratoma into the pleural cavity or adjacent organs can cause severe chest pain, hemoptysis, acute dyspnea, etc. Complications such as recurrent pneumonia, pericardial effusion, pleural effusion and great vessel invasion can sometimes occur. We encountered a case of a patient with an abrupt onset of dyspnea after persistent shoulder pain for one month. The X-ray examinations revealed a unilateral mediastinal mass with contralateral pleural effusion. Subsequent evaluations confirmed a spontaneous rupture of the teratoma into the contralateral pleural cavity.

A case is described in a girl who presented with recurrent life-threatening hemoptysis at the age of 18 months, and had been diagnosed as atrial septal defect with severe cardiomegaly which was presumed to result in pulmonary vein stenosis at the age of 6 months. Closure of atrial septal defect was associated with decreased heart size and improved pulmonary venous flow. However, recurrent life-threatening hemoptysis occurred during follow-up, Computed tomography scan demonstrated left pulmonary vein stenosis and extrinsic compression of the left bronchus by multiple soft tissue density-masses. Exploratory thoracotomy revealed single stenotic left pulmonary vein, and flat left main bronchus compressed by multiple hypertrophied lymph nodes, Unexpected endotrachial tube bleeding during left hilar dissection mandated to proceed to left pneumonectomy, The patient's postoperative course was uneventful. Follow-up chest roentgenography revealed acceptable left hydrothorax without mediastinal shifting, Nevertheless, a long-term follow-up is necessary.

The medical records of 87 patients with thyroid nodule treated from May 1992 to February 1996 were retrospectively reviewed to assess complication with age, sex, pathologic classification, location of lesions, and surgical procedures. The overall rate of complication were observed 10(11.5%) in thyroid surgery. The most common complication was transient hypoparathyroidism, which occurred in 6(6.9%) of 87 patients. The 2(2.3%) patients experienced Permanent hypoparathyroidism and each 1(1.1%) patient was reported in transient recurrent laryngeal nerve paralysis and hematoma.. Well-performed thyroid surgery usually produces few complications. More extensive resections, involving bilateral thyroidectomy are associated with a higher incidence of postoperative morbidity, in particular vocal cord paralysis and hypoparathyroidism, than procedures that consist essentially of unilateral thyroidectomy. Our experience suggests that the postoperative complication relates primarily to the surgical procedure. The low incidence of permanent complications in thyroid surgery suggests the feasibility of total thyroidectomy as the operation of choice when thyroid nodules were malignant and surgeons are familiar with the technique and indications.

Organized hematoma of the maxillary sinus is a rare, nonneoplastic benign lesion with locally destructive behavior that may mimic a malignancy. Clinically, symptoms do not usually occur while the lesion remains localized to the maxillary sinus. Because there is gradual enlargement of the lesion causing erosion and displacement of the adjacent bony structures, symptoms such as epistaxis, cheek swelling, nasal obstruc-tion, headache, and exophthalmos become manifest. Radiologically, unilateral cases are much more fre-quent than bilateral, and Waters' view shows complete opacity of the expanded maxillary sinus and some masses. CT scan shows a large heterogeneous enhancing mass causing considerable expansion of the max-illary sinus with bony erosion. On MR imaging, the mass usually has a variable signal intensity on T1- and T2- weighted images, ranging from low to high. After contrast administration, discrete areas of enhance-ment are present within the mass. Although the disease is essentially benign and nonneoplastic, differen-tial diagnosis from neoplastic disease including malignancy both clinically and radiologically has been always problematic. Accurate preoperative diagnosis of organized hematoma of the maxillary sinus is important to avoid unnecessary extensive surgery, because this condition is curative with a simple, conservative surgical approach and rarely recur. Organized hematoma of the maxillary sinus should be included in the differential diagnosis when patients have recurrent epistaxis, slow-growing mass of the cheek, nasal obstruction, and expansile mass in the maxillary sinus. A 33-year-old man was referred to the department of oral and maxillofacial surgery with a three-month history of slowly growing painful swelling of the left cheek. The mass of the maxillary sinus was resected by a Caldwell-Luc approach. Histopahtoly showed only a fibous encapsulated organized hematoma. To our knowledge, organized hematoma of the maxillary sinus has not been previously described in the Korean literature of the oral and maxillofacial surgery. We report a case of organized hematoma of the maxillary sinus presenting with an enlarging maxillary sinus mass.

Oral Lichen Planus(OLP) is a idiopathic chronic inflammatory disease with more difficult to clear and higher recurrent rate than cutaneous lesions. But, there has been no estabilished theories about the proper treatment for OLP. The purpose of this study is to examine the clinical feature, relationship with systemic disease and dental treatment of OLP patients of Korea and to gain helpful information about clinical characteristics and treatment of OLP. The subjects chosen for the study were 54 patients who had visited Department of Oral Diagnosis & Oral Medicine at Yonsei University Dental Hospital Dental Hospital and diagnosed as OLP. Previous clinical records has been reviewed and questionnaires, oral examination, laboratory examination were done and recorded. The following results were obtained : 1. Of the 54 patients, 21 were men and 33 were women with an average age of 47.8 years. 2. The most common intraoral site was bilateral buccal mucosa, followed by unilateral buccal mucosa, gingiva, vesibule, lip mucosa, glossal mucosa, palatal mucosa and mouth floor. 3. The mixed, erosive and reticular form of OLP was most frequent(83.3%) clinical form. 4. OLP patients with liver disease were 5, and drug medication patients were 7. But, we could not find its evidence of association with OLP. 5. Associated events on onset of symptom were stress, denture wearing, dental treatemtn, and common cold. 6. Associated symptoms were dry mouth, tingling, sore throat, and altered taste perception. 30.8% of patients had no specific associated symptoms. 7. Aggravating factors of symptom were peppery food, hot food, fatigue, toothpaste, salty food, sour food, tension, and conversation. Reducing factors were cold food, sleeping. 69.2% of patients had no specific reducing factors. 8. There were no significant differences between normal papulation and OLP patients in CBC, SGOT< SGPT, Serum iron, Total iron binding capacity. 66.7% of subjects were positive response to fungus study for Candida Albicans. The incidence of stress and dental treatment on onset of symptom appeared high in OLP patients. Especially, high incidence of positive response to fungus study for Candida albicans, prescription of anti-fungal agents and dental treatment considerations may be helpful to treatment of OLP.

Abrupt progression of renal scarring associated with vesicoureteral reflux (VUR) is rare in males over 2 years old of age. We report a 5 year old boy with sustained unilateral high grade VUR who experienced abrupt progression of renal scarring; he had a relative renal radionuclide uptake of 38% at 2 years of age that dropped to 8% after three years. Per his parent's wishes, he took prophylactic antibiotics for 25 months after his first febrile urinary tract infection (UTI) at 4 months old without surgical management. One episode of recurrent breakthrough infection occurred at the age of 2 years. This observation reminds us that a recommending surgical management for sustained high grade VUR associated with renal scarring might be needed. Close follow up of DMSA for renal scanning, and long term follow up of patients after the first febrile UTI are important.

A six-month old boy and a thirty-month old girl who suffered from dyspnea were admitted to our hospital. Their primary disease was congenital myopathy, and both of them had a history of recurrent pneumonia. Chest X-ray scan showed unilateral diaphragmatic eventration. To minimize the injury of weakened respiratory muscle in children with myopathy, VATS plication was performed under double lung ventilation. Each of the two patients were discharged on the 17th and 24th postoperative day. We report two cases of successful VATS plication in children with diaphragmatic eventration associated with congenital myopathy.

Background: Preauricular sinuses represent a common congenital abnormality in children. Classically, a preauricular sinus manifests as a small opening, usually near the anterior limb of ascending helix. The difficulty in the surgical treatment of preauricular sinus is the high recurrence rate. The aim of this article is to review the outcomes of preauricular sinus and to introduce our surgical technique and its prognosis. Methods: A single-institutional retrospective review was performed for all patients who had undergone excision of congenital periauricular sinus between October 2007 and April 2014. Medical records were reviewed for demographic information, wound complication, and recurrence rate. The sinus tract was visualized with the aid of preoperative dye instillation and intraoperative probe insertion. The skin next to the sinus opening was incised elliptically, and the tract itself was dissected medially to the end of the sinus tract and posteriorly to the cartilage of the ascending helix. Results: The review identified 44 patients for a total of 57 preauricular sinus tracts. The mean age at time of operation was 16.3 years with a range from 9 months to 65 years. Unilateral preauricular sinus tract was present in 31 patients (11 right and 20 left preauricular tract), and 13 patients had bilateral sinus tract. None of the patients had experienced wound issues postoperative, and there were no recurrent sinus tract formation or infection. Conclusion: Using a combination of dye instillation, probe insertion, and modified dissection, we were able to achieve a recurrence free series of preauricular sinus tract excision among a heterogenous group of patients. A large patient series is necessary to replicate the results of this study.

Objective: This observational study was to identify risk factors for vulvar cancer recurrence. Materials and Methods: In the study 107 patients with primary vulvar cancer were analyzed. Surgical treatment consisted of radical excision of the primary tumor in combination with unilateral or bilateral superficial and deep inguinofemoral lymphadenectomy through separate incisions. Patients with deeper tumor invasion >1 mm or wider than 2 cm and/or groin lymphnode metastases were referred for adjuvant radiotherapy. Those with large privary vulvar tumors received neoadjuvant radiotherapy of 30Gy followed by surgical treatment and adjuvant radiotherapy. Results: Most of patients had only primary radiotherapy to the vulva and inguinal lymph nodes and only 34.5% of patients were eligible for surgical treatment. In 5 year follow-up period 25.2% (27) patients were alive without the disease, 15.0% (16) were alive with the disease and 59.8% (64) were dead. 60.7% (65) patients experienced local recurrence and 2.8% (3) patients had distant metastases. Median survival for patients without recurrent disease was $38.9{\pm}3.2$ months and $36.0{\pm}2.6$ months with no statistically significant difference. Patients with early stage vulvar cancer had longer mean survival rates-for stage I $53.1{\pm}3.4$ months, $38.4{\pm}4.4$ months for stage II and $33.4{\pm}2.6$ and $15.6{\pm}5.2$ months for patients with stage III and stage IV vulvar cancer, respectively. The only signifficant prognostic factor predicting vulvar cancer recurrence was involvement of the midline. Conclusions: Patients having midline involvement of vulvar cancer has lower recurrence risk, probably because of receiving more aggressive treatment. There is a tendency for lower vulvar cancer recurrence risk for patients over 70 years of age and patients who are receiving radiotherapy as an only treatment without surgery, but tendency for higher risk of recurrence in patients with multifocal vulvar cancer.

Objective: This qualitative study retrospectively examined the experience and psychological impact of contralateral prophylactic mastectomy (CPM) among Southern Chinese females with unilateral breast cancer history who underwent BRCA1/2 genetic testing. Limited knowledge is available on this topic especially among Asians; therefore, the aim of this study was to acquire insight from Chinese females' subjective perspectives. Methods: A total of 12 semi-structured in-depth interviews, with 11 female BRCA1/BRCA 2 mutated gene carriers and 1 non-carrier with a history of one-sided breast cancer and genetic testing performed by the Hong Kong Hereditary Breast Cancer Family Registry, who subsequently underwent CPM, were assessed using thematic analysis and a Stage Conceptual Model. Breast cancer history, procedures conducted, cosmetic satisfaction, pain, body image and sexuality issues, and cancer risk perception were discussed. Retrieval of medical records using a prospective database was also performed. Results: All participants opted for prophylaxis due to their reservations concerning the efficacy of surveillance and worries of recurrent breast cancer risk. Most participants were satisfied with the overall results and their decision. One-fourth expressed different extents of regrets. Psychological relief and decreased breast cancer risk were stated as major benefits. Spouses' reactions and support were crucial for post-surgery sexual satisfaction and long-term adjustment. Conclusions: Our findings indicate that thorough education on cancer risk and realistic expectations of surgery outcomes are crucial for positive adjustment after CPM. Appropriate genetic counseling and pre-and post-surgery psychological counseling were necessary. This study adds valuable contextual insights into the experiences of living with breast cancer fear and the importance of involving spouses when counseling these patients.
