Xanthoma is a localized collection of tissue histocytes containing lipid. The majority of tendinous xanthomas probably occurs in the setting of hypercholesterolemia especially in bilateral Achilles tendon xanthomas. Xanthoma of the Achilles tendon is a rather rare, interesting orthopaedic condition that has important ramifications in internal medicine and dermatology because the lesion is associated with a specific disturbance of lipid metabolism. We experienced one case of normolipidemic and symptomatic Achilles tendon xanthoma. Surgical intervention was carried out for cosmetic and symptomatic reasons, the patient undergoing total resection and a reconstruction of the Achilles tendon by the combinedV-Y muscle flap and modified Lindholm technique.

Purpose: Surgical approaches to the condylar neck and subcondyle area can cause some morbidity such as, facial nerve injury, time-consuming nature and external scar etc. So many surgeons hesitate using open reduction and internal fixation for the treatment of subcondylar fractures. We report open reduction and internal fixation of subcondylar fractures in 13 adult patients via transmasseteric approach. Methods: From 2007 to 2009, 13 adults with subcondylar fracture of mandible were treated with open reduction and internal fixation via transmasseteric approach. A preauricular incision was extended downwards in a curvilinear fashion in the cervicomastoid skin crease. Skin flap was elevated above the SMAS layer. Masseter muscle was splitted at the anteroinferior edge of the parotid gland. After the fracture was reduced, fixed with appropriate plates and screws. All operation were performed under general anesthesia. Results: Mean follow-up period was 13.3 months. There were no signs and symptoms of facial nerve injury, difficulty in mouth opening, or malocclusion. Dissection time was roughly within 30 minutes. Conclusion: Transmasseteric open reduction and internal fixation of mandible subcondylar fracture can be performed with excellent visualization, and inconspicuous scar. It also offers swift access to the subcondylar area while substatially reducing the risk to the facial nerve and eliminating the complications associated with transparotid approaches.

Malignant fibrous histiocytoma after radiation therapy is very rare and its prognosis is poor. A 52-year-old male patient was admitted due to painful mass at the sternal area which developed 6 months ago. The patient had a history of radiation therapy for esophageal cancer 5 years ago. The incisional biopy disclosed sternal sarcoma. In spite of 5 cycles of chemotherapy, the m ss progressively enlarged, and an operation was performed. Total sternectomy with overlying skin and postal cartilage was performed and reconstruction was carried out with autologous rib bone graft, bilateral pectoralis klajor muscle flap and skin graft. The microscopic examination was consistent with malignant fibrous histiocytoma. The postoperative course was uneventful and the patient was discharged on postoperative 36 day.

We firstly described a box jellyfish, Carybdea brevipedalia collected from the southern coasts of Korea. It is morphologically characterized by gastric phacellae, a special digestive system of cubozoan jellyfish, and velarium, the thin muscle flap forming the opening of the subumbrellar cavity. The phacellae are linear-shaped, comprising numerous cirri branched from multiple roots. Each root also has multiple numbers of cirrus bundles. Basis of velarial cannels parts into two branches in each octant of velarium. Its geographic distributions were limited to Jeju-do and the middle-southern coasts where the organisms are seriously hazardous to bathers in summer. Numerous individuals and/or large-sized populations were observed specifically from beaches at Jeju-do, Namhae-do and a small fishing port of Namildae, while only a small amount of the individuals was observed in Gamak Bay, Jaran-Goseung Bay, and Geoje-do. We confirmed molecular identity of the Korean C. brevipedalia with comparison of nuclear ribosomal DNA sequences. Until now, Carybdea brevipedalia is the only cubozoan species reported to be distributed in Korean waters.

Autologous breast reconstruction after mastectomy in breast cancer patient is now increasing. The deep inferior epigastric artery (DIEA) free flap is well known as an ideal donor site for the microsurgical breast reconstruction. The branching pattern of the DIEA was well described in the literature. In that study, DIEA has three branching patterns near the arcuate line. We describe a case in which branching variation of the DIEA before entering the posterior surface of the rectus abdominis muscle. In three cases, DIEA originated from the external iliac artery ascended as a double trunk at 1cm, 2cm, and 4cm above the originating point, respectively. In one case, DIEA ascended as a single trunk along the linea alba toward to the umbilicus until it supply overlying subcutaneous tissue. Preoperative 3D computed tomographic angiography to identify the anomaly is recommended and meticulous dissection to the originating point of DIEA is needed.

Purpose: To report the case of recurred malignant proliferating trichilemmal tumor on scalp Methods: Case report and literature review Results: A 40-year-old man presented with a recurred malignant proliferating trichilemmal tumor, which developed on the occipital area. It was $8{\times}9{\times}4.5cm$ in size, protruded, firm and non-tender mass. This tumor was widely excised including normal skin margin and pericranium. Immediate reconstruction using free latissimus dorsi muscle flap and skin graft were done. Histopathologic examination revealed abrubt, compact trichilemmal keratinization in the central area of lobular epithelial proliferation. Conclusion: There has been no recurrence of tumor during follow-up period of nine months without adjuvant chemotherapy or radiotherapy.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign mesenchymal lesion with incidental histologic findings. Surgical excision is recommended as the treatment of choice for PASH, although the recurrence rates after excision range from 15% to 22%. A 46-year-old-female presented with a six-month history of bilateral breast enlargement and painful sensation mimicking inflammatory carcinoma. Imaging studies demonstrated innumerable enhancing nodules in both breasts. Due to the growth of the lesions and progressive clinical symptoms, bilateral subcutaneous mastectomy was performed. Grossly, the specimens were round and well-circumscribed, and the histologic examination revealed PASH. After mastectomy, we created a pocket with the pectoralis major muscle and a lower skin flap, which was deepithelized. Anatomical mammary implants were inserted, and the nipple areolar complex was transferred to a new position as a free graft. The aesthetic result was satisfactory after twelve months of follow-up.

An esophageal perforation following anterior cervical fusion is rare. Early development of an esophageal perforation after anterior cervical fusion is usually due to iatrogenic injury from retraction, injury associated with the original traumatic incident, improperly placed instruments or a bone graft. A 31-year-old man had a cervical dislocation and spinal cord injury because of severe cervical trauma after a traffic accident. He was quadriplegic and had no feeling below T4 dermatome. Anterior decompression of the cervical spine and anterior fusion with mesh with autobone were performed. An esophagocutaneous fistula occurred 7 days after anterior cervical surgery. A second anterior surgery was done because of pus drainage. The mesh was changed with an iliac bone graft, and the esophagocutaneous fistula site was primary repaired, but pus continued to drain. Conservative treatment, which consisted of wound drainage and intravenous administration of antibiotics, was tried, but was unsuccessful. After all, we removed the plate and screws, but did not removed the iliac bone graft, We closed the esophageal fistula, and transposed the sternocleidomastoid muscle flap to the interspace between the esophagus and the cervical spine. The wound to the esophagus was well repaired. In conclusion, precautionary measures are needed to avoid the complication, and adequate treatment is necessary to resolve those complications when they occur.

Post-Pneumonectomy Empyema[PPE] is a relatively uncommon but serious complication. And the management of it remains a disturbing and controversial area in the field of general thoracic surgery. Many methods have described and have had varying degrees of success. For the purpose of providing the guideline for management of post-pneumonectomy empyema, we reviewed our experiences of treatment of PPE from January 1985. to December 1992. There were 17 cases, which consist 7.9% of all pneumonectomy cases for that period. There were 13 male and 4 female patients with mean age of 47.1$\pm$ 16.2 yrs old. Both chest has the same incidence. The most common disease for prior pneumonectomy was tuberculosis, but the PPE was the most frequently occurred in empyema. The duration between pneumonectomy and PPE was 44.7 $\pm$81.1 months, where 58.8% of patients occurred within 1 month. Fever was the most frequent complaint and wound dischrge was detected in less than half of patients. There were 2 in-hospital mortalities.Mostly, in 13 cases, we did Eloesser operation. Five of them could finish second Clagett procedure, but one had recurrence. Four bronchopleural fistular patients underwent 3 single stage muscle flap closure and 1 direct closure with modified Clagett procedure. None had recurrence. Mean follow-up duration is 30.9\ulcorner22.3 months. There was 1 late death which was not related to PPE but to Malignancy recurrence.

Introduction: Since 1996, Dr. James Norman has successfully performed mimimally invasive radio-guided parathyroidectomy(MIRP) using intraoperative nuclear mapping with $^{99m}Tc$ sestamibi scanning and radioactivity detection probe. Objectives: We aimed to introduce this new surgical technique and evaluate it's efficacy by our own experiences. Method: From May to October 1999, five consecutive patients with primary hyperparathyroidism underwent parathyroidectomy by using modified MIRP technique. $^{99m}Tc$ sestamibi scanning was performed 1.0 or 1.5 hour before operation. After intraoperative localization of the tumor under the guidance of quantitative gamma counting with a NEVIGATOR probe, an unilateral small skin incision(3.0-4.0cm) was placed. Without a skin flap, the strap muscle was directly divided with the use of a Harmonic scalpel. After careful dissection, the parathyroid tumor was removed. Result: In all patients, a single adenoma could be easily detected and removed by this new technique. Mean incision length was 3.2cm(3.0-4.0cm) and operative time ranged from 40 to 110minute. All the patients were discharged within 2 days of surgery without any complication. Conclusion: This new operative technique could become the most minimally invasive alternative to the standard operative procedure for parathyroid adenoma.
