Pediatric lymphangioma can occur at any site. However the neck is the most common site. There are two treatment modalities (surgical excision and intralesional injection) for lymphangiomas. But, the treatment guide line for lymphangioma has not been established, yet. The aim of this study is to establish the treatment guide line based on our experience with lymphangiomas. Medical records of 82 cases of lymphangioma were reviewed retrospectively. On MRI (magnetic resonance image) findings, lymphangiomas were divided into 4 groups by the proportion of the cyst bigger than 2 cm in diameter of the tumor; group A-proportion of cyst occupies more than 75%, group B-proportion of the cyst 50~75%, group C-25~50%, and D in less than 25%. All patients were treated with OK-432 intralesional injection as the initial treatment. The effective response rates of OK-432 in group A & B were 88.2% and 88.8%, respectively. Group C response was 38.0% and D only 20.0%. Twenty-three patients received surgical excision. The result of surgical excision was generally satisfactory. Surgical site infection occurred in 1 case and postoperative bleeding in 1 case. Theses results indicate that intralesional injection of OK-432 could be the first line therapy in group A & B. In group C, OK-432 would be better as the first line therapy than surgery. For the group D, surgical excision should be the first line of treatment.

Background: Lipomas are common benign tumors of mesenchymal origin that are composed of mature adipocytes. Giant lipomas have a diameter ≥ 10 cm in one or more dimensions or weigh at least 1,000 g. The surgical excision of a giant lipoma requires extensive dissection, increasing the risk of a seroma, which can cause surgical site complications such as wound infection and necrosis. Sclerotherapy with Abnobaviscum (Viscum album extract) is a relatively new technique used to reduce malignant pleural effusion. In this study, we evaluated the effectiveness of prophylactic sclerotherapy using Abnobaviscum to decrease seroma after giant lipoma excision. Methods: We conducted a retrospective medical record review of patients who underwent surgical excision for giant lipoma of the neck from January 2019 to December 2022. Sclerotherapy was performed on the first postoperative day in patients who consented to the procedure, and Abnobaviscum was instilled through the existing Hemovac drain. We compared the clinical course between those who underwent postoperative sclerotherapy and those who did not. Results: Among the 30 patients who underwent giant lipoma excision, we applied sclerotherapy with Abnobaviscum to 15 patients. The average time from surgery to Hemovac removal was statistically shorter in patients who underwent sclerotherapy (p= 0.004). Furthermore, seroma formation was significantly reduced in patients receiving sclerotherapy (p= 0.003). Conclusion: In patients undergoing giant lipoma excision, sclerotherapy using Abnobaviscum helps reduce postoperative seroma formation during the initial postoperative period. It can be an excellent method to reduce complications related to seroma and attenuate patients' postoperative burden.

Purpose: The purpose of this study was to identify the effect of the exchange of saline used in surgical procedures on surgical site infections. Method: Patients with stomach cancer were assigned to the experimental group or to the control group by random sampling, respectively. The experimental group received an exchange of saline during the operation right after the excision of the stomach in a gastrectomy but the control group did not. Data were collected from the medical charts of 34 patients from Dec. 1, 2002 through May 31, 2003. Result: The surgical site infection rate of the experimental group was 5.9% while surgical site infection rate of the control group was 17.6%. In total, the surgical site infection rate was 11.8%. The experimental group maintained a normal level of WBC on post operative day 3; however, the control group, showed an increase of WBC on post operative day 3. Conclusion: The exchange of saline used in an operation immediately after the excision of the stomach in a gastrectomy decreases the contamination level of saline used in the operation, and can prevent surgical patients from a surgical site infection.

Leiomyosarcoma is a rare form of soft tissue neoplasm, with only 1% to 5% occurring in the head and neck region. Current recommended treatment suggests surgical excision with a wide lateral margin, but no definite guidelines regarding excisional margin have been established yet. Recently, complete excision with a narrow surgical margin has been recommended, and the authors present a case of cutaneous leiomyosarcoma on the face that was successfully managed by complete removal with a narrow excisional margin. A 74-year-old woman presented with a 3 cm sized, rapidly growing cutaneous mass on her right preauricular area. Preoperative biopsy of the skin lesion suggested a cutaneous leiomyosarcoma. The authors performed complete surgical excision with a 1 cm lateral margin, and the resulting skin defect was repaired with bilateral V-Y advancement local flaps. Histopathology and immunohistochemistry evaluation confirmed a moderately differentiated cutaneous leiomyosarcoma, with negative margin involvement. The patient refused of any additional treatment, but showed no locoregional recurrence during the 1.5 years of postoperative follow-up period. With a regular postoperative follow-up, cutaneous leiomyosarcomas may be successfully treated with a narrow surgical margin.

In 1940, Kasabach and Merritt first described the association of a large vascular tumor and thrombocytopenia and termed this Kasabach-Merritt(KM) syndrome. It is characterized by a rapidly enlarging vascular anomaly and consumptive coagulopathy with thrombocytopenia, prolonged prothrombin time and partial thromboplastin time, hypofibrinogenemia, and the presence of D-dimer and fibrin split product, with or without microangiopathic hemolytic anemia. This is a potentially life-threatening condition with mortality rates from 20 to 30% as a result of severe sepsis, coagulopathy, or invasion of vital organs. Treatment modalities are corticosteroids, interferon alfa-2a or 2b, chemotherapy(vincristine, cyclophosphamide, etc.), aspirin, dipyridamole, com- pression, radiation therapy, embolization of feeding vessels and surgical excision. A standard treatment regimen for KM syndrome has not been established and most reports on definitive management of these complex vascular lesions have been anecdotal, involving small numbers of patients. The authors have successfully treated a patient of KM syndrome with actively bleeding huge hemangioma by surgical excision. They present it with the review of articles.

Purpose: The purpose of this study is to compare the clinical outcome of excision versus osteosynthesis of type II accessory navicular performed by a single surgeon. Materials and Methods: Cases of 14 feet treated with excision and 13 feet by osteosynthesis for type II accessory navicular of 25 patients from 2002 to 2009 were included in this study. Radiological measurements and American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scale was evaluated. Results: AOFAS midfoot scale of both excision and osteosynthesis groups at last follow-up showed improvement from pre-operation. However, there was no statistical difference in AOFAS midfoot scale and subjective satisfaction between the two groups at last follow-up. In detail of AOFAS midfoot scale, pain and footwear requirements showed statistically favorable results for the excision group, while activity limitation and support showed statistically favorable results for the osteosynthesis group. Subjective recovery time returning to daily activities and starting rehabilitation exercise were 14.6 weeks in the excision group and 13.7 weeks in the osteosynthesis group (p=0.025, Mann-Whitney). Suture anchor loosening was observed in one case in the excision group and non-union in two cases in the osteosynthesis group. Conclusion: Both excision and osteosynthesis are favorable surgical methods, but each method has advantages and possible complications such as suture anchor loosening or non-union. Surgeon's preference, patient's chief complaint, specific needs of patient after the operation and consideration of the size of accessory navicular can be a criteria to consider when selecting a surgical method.

Clear cell hidradenoma is a skin adnexal tumor originating from eccrine glands. The risk of local recurrence after surgical resection exceeds 50%, and 6-19% of cases are malignant. The rarity of clear cell hidradenoma and its diverse histological findings make this type of tumor a diagnostic challenge. We present a case of recurrent clear cell hidradenoma of the posterior neck in a 70-year-old woman. The tumor recurred once after complete excision, and did not recur again after 1-cm wide excision and reconstruction with a local bilobed flap. Recurrent clear cell hidradenomas are activated by surgical stimulation, increasing the risk for metastasis. Therefore, we suggest that wide excision with confirmation of a tumor-free margin by frozen-section biopsy should be the first-line treatment for recurrent benign clear cell hidradenoma.

Background and Objectives : Surgery is considered the primary treatment for intracordal cyst. However, patients who had undergone surgery are still subject to recurrence and continued voice changes. Intracordal cysts naturally disappear in some patient population. Cyst does not always recur in patients who had received partial surgical removal, too. Contradicting results raises a question whether complete surgical removal of intracordal cyst is necessary and demonstrate need for better treatment. Herein, the author proposes novel surgical method technique intralaryngeal needle technique (INT), a technique using surgical needle for not only injection but also for aspiration and excision of cyst. This study aims to examine the potential of intralaryngeal needle technique in treating intracordal cysts. Materials and Methods : Surgical procedures were done on in-patients diagnosed with intracordal cyst. 23 patients received follow-up screening after the surgery for one year. Patients' subjective satisfaction levels, acoustic measures, aerodynamic measures, laryngeal stroboscopic results were compared before and after the treatment. Results : Overall patients were satisfied with novel surgical excision method. In terms of aerodynamic measures, maximum phonation time, mean air flow rate improved after the surgery. In terms of acoustic measures, Jitter, Shimmer, NHR, and voice pitch changes after the treatment showed statistically significant differences. Laryngeal stroboscopy results showed significant decreases in cyst sizes. Post-surgery patients had improved mucosal waves and amplitudes values. Conclusion : The results show the validity of intralaryngeal needle technique in reducing intracordal cyst size by excision, aspiration, and injection. The author believes this novel technique can be used as an alternative surgical method for intracordal cysts.
