Dematofibrosarcoma protuberans(DFSP) is a moderate-degree malignant tumor with high recurrence rate and low metastasis rate, from soft tissue. Principle of treatment is wide excision or Mohs micrographic surgery(MMS). Although wide excision has been performed with surgical margins of 2-5 cm until nowadays, there are problems of preservation of surrounding normal tissue. Therefore the authors tried to identify desirable surgical margins and operative method. From January 1999 to April 2003, 12 patients with DFSP were operated. We applied different surgical margins and operative methods according to the location of lesions. On the face, we performed MMS with surgical margin of 3-4 mm in 2 cases although there are problems of operation time and expense. But on the extremities and trunk, we performed authors' method to begin excising with surgical margins of 1 cm and excise extensively with MMS by 1 cm in 4 cases after April, 2001 although we had performed wide excision with surgical margin of 3 cm in 6 cases before. There was no recurrence or metastasis in the follow-up period. So we think that author's method is effective in surgical excision of DFSP

Background Xanthelasma palpebrarum (XP) is a benign disorder manifesting as yellowish cholesterol-laden plaques on the eyelids. This paper presents the outcomes in patients with XP who have undergone surgical excision as the main modality of treatment. Methods A retrospective review of patients who received surgery for xanthelasma palpebrarum from March 2007 to March 2011 was conducted. Patients were classified into four grades according to the location and extent of the lesion, with grade I being the mildest and grade IV being the most diffuse. Simple excision was performed in grade I and II lesions, while local flaps and skin grafts were performed in the more advanced grades. Results Ninety-five cases from March 2007 to March 2011 were included in this study. 66 cases (70%), were treated by simple excision. Twenty-four cases (25%) and 5 cases (5%) were treated by simple excision in combination with or without local flaps and skin grafts. In approximately 1/4 of the patients, orbicularis oris muscle involvement was observed. 4 patients (4.2%) developed scar contracture postoperatively, which required a secondary procedure. Recurrence was reported in 3 patients (3.1%). Otherwise. There were no other reports of major complications or disfigurement. Conclusions We found that for lesions involving the deep dermis and/or muscle, surgical excision was the most appropriate therapeutic option.

Aim: To compare recurrence rates of large loop excision of the transformation zone (LLETZ) with those of contour-loop excision of the transformation zone (C-LETZ) in the management of cervical intraepithelial neoplasia (CIN). Materials and Methods: The medical records of 177 patients treated consecutively by LLETZ and C-LETZ for CIN at Rajavithi Hospital between 2006 and 2009 were retrospectively reviewed. Results: Of the 87 women in the C-LETZ group, 2 cases (2.30%) had recurrence compared with 13 cases (14.4%) of the 90 women in the LLETZ group, the higher recurrence rate in the latter being statistically significant (p<0.05). Median times of follow up in the C-LETZ and LLETZ groups were 12 months and 14 months respectively (p>0.05). The C-LETZ group showed less intraoperative bleeding compared to the LLETZ group, but the rate of achievement of single specimens and positive margins were similar in the two groups. Conclusions: The present study demonstrated the superiority of C-LETZ over LLETZ in terms of efficacy; C-LLETZ is associated with a lower recurrence rate and also carries a smaller risk of intraoperative bleeding than LLETZ. The rotating technique still has a potential role in treating precancerous lesions of the cervix.

Congenital melanocytic nevus consists of congregations of nevomelanocytes. It is found in approximately 1% of new born infants. Congenital melanocytic nevus needs to be excised before it transforms into a malignant lesion. Many strategies have been attempted for the removal and reconstruction of the nevus. Serial excision enables wound closure to be accomplished with a shorter scar than if the original lesion was elliptically excised in a single stage and reorientation of the scar closer to the relaxed skin lines. The routine utilization of an elliptical serial excision as a standard method of closure often leads to the formation of elongated scars and waste of skin. The "Cogwheel pattern" serial excision is a new technique for reducing the size of the nevus efficiently. Reducing the final scar length, distributing the tension over many directions, and having the chance of decrease in operation numbers are ultimately achieved with the use of the "Cogwheel pattern" serial excision.

56 dogs that had undergone surgical excision of skin lesion tumors at Veterinary Medical Teaching Hospital in Seoul National University from 2000 to 2005 were evaluated retrospectively. The ratio of cases with benign versus malignant tumor types were 1.5:1.48 cases received surgical excision alone and 8 cases received adjuvant treatments. 42 cases were followed postoperative recurrence time and survival time (25 benign, 17 malignant). 25 cases (25/42, 60%) had no recurrence after surgical excision. In malignant tumor types, 5 cases (5/17, 29%) had recurrence and the median recurrence time was 157 days, and 8 cases (8/17, 47%) died due to tumors and survival time was 125 days. In benign tumor types, only 2 cases (2/25, 8%) had recurrence and the median recurrence time was 273 days.

Postoperative atlantoaxial rotatory subluxation (AARS) is a rare complication that develops almost exclusively in children following oropharyngeal and otologic surgeries, proposing that oropharyngeal inflammatory responses and excessive head rotation are responsible factors. However, there have been no reports of AARS after excision of a nevus on the head and neck. Here, we present two cases of AARS following limited head rotation during simple nevus excision. Patient 1, a 9-year-old girl, complained of neck pain and limited range of motion after excision of the nevus on the neck. After 2 months, computed tomography and magnetic resonance imaging finally revealed AARS with a ruptured transverse atlantal ligament. A month of halo traction was required for the treatment. Patient 2, an 11-year-old girl, presented with immediate pain and limited neck extension after tissue expander insertion under the upper chest and excision of the nevus on her left cheek. The diagnosis was promptly made using cervical spine radiography. A cervical collar was applied for 1 month. Both patients recovered without any complications after treatment. This report highlights the importance of suspicion for AARS after surgery regardless of surgical duration or amount of head rotation.

Aggressive angiomyxoma (AA) is a very rare mesenchymal tumor most commonly found in the pelvic and perineal regions. For the complete excision of retrorectal tumors, with extension through the levator muscle into the ischioanal space, open anterior and posterior approaches are typically required. Herein, we report our experience with robotic excision of a giant presacral AA with extralevator extension into the ischioanal space and extraction via Pfannenstiel incision, which we found to be technically feasible, efficacious, and safe to perform. Mayo Clinic Institutional Review Board exemption status was obtained for this study.

Purpose: Several methods of the nipple reduction have been reported. However, the methods described previously are difficult or have some demerits. This study proposes a simple technique for reduction of the nipple height as well as diameter. Methods: The purposed nipple height is marked. A pentahedral design of excision was marked around the nipple. Local anesthetic solution was infiltrated and a 4 - 0 Nylon traction suture was applied at the nipple apex. Excision of the nipple inside both two triangles and a rectangle was made. Remaining two flaps were approximated using 5 - 0 Nylon simple interrupted sutures. However, a part of wound closure was not done in the central area of the nipple. Results: 83 patients(166 nipples) underwent this procedure from December 1999 to December 2008. Follow up ranged from 6 months to 2 years with a mean of 10 months. 78 patients were female and 5 patients were male. No major complication occurred and remaining scars were very inconspicuous. Conclusion: This simple technique has the advantage of nipple reduction in both height and diameter, and provides good aesthetic outcomes.

Acromioclavicular joint cyst is a extremely rare condition, usually occuring in the presence of a wide communication between glenohumeral and acromioclavicular joint in patients with a full thickness rotator cuff tear. Removal of cyst only is reported with high recurrence rate. There was no case previously reported in Korea. We report a case of recurred acromioclavicular joint cyst with a massive rotator cuff tear after simple excision, which was treated by excision of cyst, acromioplasty and resection of the lateral end of the clavicle.

Mesenteric and omental cysts are rare lesions in childhood. These cysts are morphologically and pathologically similar to lymphangiomas that occur in other parts of the body. From 1980 to 1997, 8 children were diagnosed and treated for mesenteric or omental cysts. Their ages ranged from 18 days to 6 years. There were 5 boys and 3 girls. The main presenting symptom was abdominal pain. Operative procedures were complete cysts excision, complete excision with intestinal resection, or complete excision with intestinal resection and colostomy. Accurate preoperative diagnosis was possible with the current ultrasonographic imaging techniques. Complete excision of the lesion was possible in all patients and results were excellent.
