Purpose: Management of the soft tissue defect in the lower extremity caused by trauma has always been difficult. Coverage with local and free muscle flaps after complete surgical excision of necrotic soft tissue and bone is a major strategy for treatment. There is no doubt that muscle provides a good blood supply, thus improving bone healing and increasing resistance to bacterial inoculation. However, accompanying problems are seen in cases with shallow dead space. This research was conducted to assess the efficacy of raising anterolateral thigh flaps and transferring them to the defect after complete debridement of non-viable, infected, and scar tissue as an alternative way to use local or free muscle flaps. Methods: From March 2005 to October 2007, 18 cases of soft tissue defect on lower extremities were re-surfaced with an anterolateral thigh perforator free flap. Results: The follow-up period ranged from 1 to 31 months with a mean of 15.9 months. All flaps survived completely. Satisfactory aesthetic and functional results were achieved. Under a two-point discrimination test, 13 patients had sensory recovery from 11 mm to 20 mm after 6 months postoperatively. Conclusion: Reconstruction of the lower extremity with anterolateral thigh perforator free flaps after appropriate debridement is a good alternative way to use local or free muscle flaps.

Spinal extradural arachnoid cyst (SEAC) is a rare disease and has surgical challenges because of the critical surrounding anatomy. We describe the rare case of a 58-year-old woman who underwent extradural cyst total excision with dural repair and presented with refractory cerebrospinal fluid (CSF) leakage even though two consecutive surgeries including dural defect re-repair and lumbar-peritoneal shunt were performed. The authors covered the sacral defect using bilateral gluteus maximus muscle flap in tongue in groove and wrap around pattern for protection of visible sacral nerve roots and blockage of CSF leakage point. With the flap coverage, the disappearance of cyst and fluid collection was confirmed in the postoperative radiological finding, and the clinical symptoms were significantly improved. By protecting the sacral nerve roots and covering the base of sacral defect, we can minimize the risk of complication and resolve the refractory fluid collection. Our results suggest that the gluteus muscle flap can be a safe and effective option for sacral defect and CSF leakage in extradural cyst or other conditions.

Currarino syndrome is a hereditary syndrome characterized by the triad of a sacral bony defect, presacral mass and anorectal malformation. We retrospectively reviewed 13 Currarino syndrome patients who were treated in our center between 1997 and 2010. Demographic data, initial symptoms, initial diagnosis. pathologic diagnosis of presacral mass, associated anomalies and managements were analyzed. There were 8 boys and 5 girls. Four patients were diagnosed as Currarino syndrome immediately after birth with failure of passage of meconium and abdominal distension. Four patients underwent surgery for imperforate anus immediately after birth and W8re diagnosed as Currarino syndrome later and underwent reoperation. Three patients were diagnosed during work-up and management with of the tentative diagnosis of Hirschsprung's disease. Diagnosis of the remaining two patients was at the age of 26 months and 9 years and anorectal malformation was not associated. Twelve patients showed hemi-sacrum and one patient showed bilateral sacral subtotal agenesis. Two patients without anorectal malformation underwent presacral mass excision, untethering of spinal cord and repair of myelomeningocele. Six out of 8 patients, excluding 3 that expired or were lost to follow up, with anorectal malformation underwent colostomy, presacral mass excision, untethering of spinal cord, repair of myelomeningocele, posterior sagittal anorectoplasty and colostomy repair. One patient underwent only posterior sagittal anorectoplasty after colostomy. One waits the scheduled operation only with Hegar dilatation. Pathologic examation of presacral masses showed myelomeningoceles in 4 patients, lipomyelomeningoceles in 3 patients and dermoid Cyst in one patient. Teratoma was combined in 2 patients. Eight patients needed neurosurgical operation for spinal cord problems. Seven patients had urologic anomalies and two of them underwent operation. Currarino syndrome should be considered as a differential diagnosis in pediatric patients with abdominal distension, constipation and anorectal malforlnation. For proper evaluation and treatment, a multi-disciplinary approach is recommended.

Forehead osteomas are benign but can pose aesthetic and functional problems. These osteomas are resected via bicoronal or endoscopic approach. However, large osteomas cannot be removed via endoscopic approach, and bicoronal approach can result in damage to the supraorbital nerve with resultant numbness in the forehead. We present a new approach to resection of forehead osteomas, with access provided by an anterior hairline incision and subcutaneous dissection. Three patients underwent resection of the forehead osteoma through an anterior hairline incision. The dissection was carried in the subcutaneous plane, and the frontalis muscle and periosteum were divided parallel to the course of supraorbital nerve. The resulting bony defect was re-contoured using $Medpor^{(R)}$. All three patients recovered without any postoperative infection or complication and symptoms. Scalp sensory was preserved. Aesthetic outcomes were satisfactory. Patients remain free of recurrence for 12 months of follow up. The anterior hair line approach with subcutaneous dissection is an effective method for removal of forehead osteoma, since it offers broad visualization and hides the scar in the hairline. In addition, the dissection in the subcutaneous plane avoids inadvertent injury to the deep nerve branches and helps to maintains scalp sensation.
Papillary fibroelastoma is a rare benign tumor of the heart. A 21-year-old man presented with dyspnea on exertion and echocardiogram showed a small round mass attached to the anterolateral papillary muscle. After excision of the mass, including anterior papillary muscle, chordae tendinae, and anterior leaflet, he underwent mitral valve re-placement with a mechanical valve. He was discharged on anticoagulant therapy without further problems.
Background: There are limited studies on oncoplastic breast conserving surgery in Asian women. We aimed to determine the applicability and safety of oncoplastic surgery, highlighting the specific circumstances when it will be most useful and compare our preferred technique with the worldwide practice of oncoplastic approaches. Materials and Methods: Breast cancer patients who underwent oncoplastic breast conserving surgery at a single institution from 1st May 2014-31st March 2015 were included. Data on patient demographics, tumor characteristics and the type of oncoplastic surgery performed were collected. Results: Nineteen breast cancer patients were identified. 42.1% of patients had grade I ptosis. The indications for surgery included a large tumor to breast size ratio (52.6%), multifocal/multicentric lesions (36.8%) and asymmetric breasts (10.6%), averting a mastectomy in 89.4%. Round block was the commonest technique in 63% of patients, in contrast to the inverted T pattern most frequently used in renowned institutions in the West. Mean and median tumor size and weight of specimen were 29.4/25mm (11 - 75mm) and 77g/64g (10 - 246g) respectively. Re-excision rate was 10.5%. Complete mastectomy was performed for one patient. One patient developed wound dehiscence which was treated conservatively. Cosmetic outcome was rated as excellent/good by 94.7% of patients. The patients remained clinically well after a median 16 months follow up. Conclusions: Oncoplastic breast conserving surgery is useful in a specific subgroup of Asian patients with a relatively small breast volume and minimal ptosis. Round block was the commonest technique in our series, in contrast to the worldwide utility of oncoplastic techniques. It is oncologically safe and has good cosmetic outcomes.
Benign lung tumors compose a heterogeneous group of solid growths that present variations in clinical features, depending on whether the origin is within the bronchus on lung parenchyma or from visceral pleura. Benign tumors of the lung are relatively uncommon, and series are to be found in the literature and the classification of benign tumors of the lung continues to be controversial because of disagreement concerning the origin and prognosis of many common lesions. We adopt Liebows original classification but excluded bronchial adenoma which no longer considered as benign tumor and added pulmonary A-V fistula and congenital cystic adenomatoid malformation. We analyzed 61 cases of benign tumors which were composed of 16 original Korean cases and 45 cases which were reported on journal of Thoracic & Cardiovascular Surgery. The results were. [1] Incidence; Of 61 cases, chondromatous hamartoma was 2 cases [41 %], congenital cystic adenomatoid malformation 10 cases [16.4 %], pulmonary A-V fistula 5 cases [8.1 %], sclerosing hemangioma 4 cases [6.5 %], teratoma, plasma cell granuloma & mesothelioma were 3 cases [4.9%], Castlemans disease 2 cases [3.3%], and mucous gland adenoma, paraganglioma, and leiomyoma 1 case [1.6 %]. [2] Age & Sex distribution; Male 30 cases and female 31 cases. Mean age was 31.4 years old. [3] Main symptom; was coughing, 32.8%, and no symptom, 24.6%. [4] Sixty eight percentage of chest film showed mass density, and 4 cases showed calcification, 2 cases had lobulation. [5] Size of mass was large and multiple mass was 2 cases. Endobronchial tumors were 9 cases, 14.9 %. [6] Three cases of endobronchial tumor were preoperatively diagnosed by bronchoscopy and 2 cases of pulmonary A-V fistula were diagnosed by pulmonary arteriography. [7] Seven cases, 11.5%, had associating diseases such as bronchogenic cyst, thymic cyst, Schwannoma, situs inversus, bronchiectasis and bronchogenic carcinoma. [8] Minor resection such as excision 8i: wedge resection were 15 cases, 26.2 %, and 6 cases, 75.4 %, of lobectomy were performed including 5 cases of pneumonectomy 5 cases had. [9] Postoperative complications; One case, 1.6 %, expired due to respiratory insufficiency. Two cases had re-operation due to bleeding and hemoptysis.
Preauricular sinus and preauricular skin tag are common childhood congenital anomalies. It is important for the pediatric surgeon to be familiar with the embryology and differentiation of head and neck structure to accurately diagnose and treat these lesions. Seventy eight patients with preauricular sinus and twenty-eight with preauricular skin tag treated in the Department of Pediatric Surgery at Hanyang University Hospital from January 1981 to May 2002 were reviewed to determine relative frequency, clinical classification and appropriate treatment. The male to female ratio of preauricular sinus was 1:1.2, and preauricular skin tag was 1:1. The most commonly presenting age of sinus and skin tag was before 5 year (62.8%) and before 1 year (53.6%). Twenty nine of 78 cases of preauricular sinuses were on the left, 25 on the right and 24 bilateral. Signs of infection were seen in 73.0% of patients with preauricular sinus at operation. Only 31.3% of lesions were infected in patients less than one year of age, but 89.5% between 3-5 years and 100% between 5-8 years. Cartilage was present in five patients with preauricular skin tag. Although re-operation due to wound infection was necessary in four cases, no recurrences were found. The preauricular sinus is a common anomaly in childhood, and has had a relatively high recurrence rate. But most of the recurrences were due to incomplete resection because of combined infection. Initial proper diagnosis and early operation are very important. Identification of the exact anatomical location of sinus tract is necessary because total excision of the lesions including those tracts is the only way to prevent recurrence.
Seventy four patients with soft tissue sarcomas treated by postoperative radiotherapy in the Department of Therapeutic Radiology, Seoul National University Hospital between August 1979 and September 1990 were analyzed. The follow-up Period ranged from 3 to 145 months with a median of 51 months. Liposarcoma and malignant fibrous histiocytoma(MFH) constituted $54\%$ of the cases and the histologic grades of tumors are as follows: grade I, 23 cases; grade II, 17 cases; grade III, 24 cases: unknown grade, 10 cases. The patients were treated by marginal(17 cases), wide(55 cases) or compartmental(2 cases) excision followed by Postoperative radiotherapy. The total radiation doses were 4200-8820 cGy (median 6000 cGy), 180-200 cGy daily. 5 times per week. Of 74 Patients, 35 ultimately failed. The local control was $62.2\%$ at 5 years and cumulative risk of distant metastasis was $22,3\%$ at 5 years. The overall survival and disease free survival were $72.3\%$, and $53.3\%$ at 5 years, respectively. Survival after appearance of metastasis was $15.1\%$ at 3 years. Patients with liposarcoma experienced better local control than those with other histologic type and tumor grade and surgical resection margin significantly correlated with local recurrence, distant metastasis and overall survival on univariate analysis. In conclusion, re-excision is needed for patients with positive surgical resection margin to improve local control and further therapeutic measures using effective chemotherapy should be explored in the hope of improving overall survival.

Aboriginal and Torres Strait Islander people comprise about 2.5% of the Australian population. Cancer registry data indicate that their breast cancer survivals are lower than for other women but the completeness and accuracy of Indigenous descriptors on registries are uncertain. We followed women receiving mammography screening in BreastScreen to determine differences in screening experiences and survivals from breast cancer by Aboriginal and Torres Strait Islander status, as recorded by BreastScreen. This status is self-reported and used in BreastScreen accreditation, and is considered to be more accurate. The study included breast cancers diagnosed during the period of screening and after leaving the screening program. Design: Least square regression models were used to compare screening experiences and outcomes adjusted for age, geographic remoteness, socio-economic disadvantage, screening period and round during 1996-2005. Survival of breast cancer patients from all causes and from breast cancer specifically was compared for the 1991-2006 diagnostic period using linked cancer-registry data. Cox proportional hazards regression was used to adjust for socio-demographic differences, screening period, and where available, tumour size, nodal status and proximity of diagnosis to time of screen. Results: After adjustment for socio-demographic differences and screening period, Aboriginal and Torres Strait Islander women participated less frequently than other women in screening and re-screening although this difference appeared to be diminishing; were less likely to attend post-screening assessment within the recommended 28 days if recalled for assessment; had an elevated ductal carcinoma in situ but not invasive cancer detection rate; had larger breast cancers; and were more likely than other women to be treated by mastectomy than complete local excision. Linked cancer registry data indicated that five-year year survivals of breast cancer cases from all causes of death were 81% for Aboriginal and Torres Strait Islander women, compared with 90% for other women, and that the former had larger breast cancers that were more likely to have nodal spread at diagnosis. After adjusting for socio-demographic factors, tumour size, nodal spread and time from last screen to diagnosis, Aboriginal and Torres Strait Islander women had approximately twice the risk of death from breast cancer as other women. Conclusions: Aboriginal and Torres Strait Islander women have less favourable screening experiences and those diagnosed with breast cancer (either during the screening period or after leaving the screening program) have lower survivals that persist after adjustment for socio-demographic differences, tumour size and nodal status.
