Fournier's gangrene is a synergistic necrotizing fasciitis of the perineal, perirectal and urogenital area and can be fatal unless treated in early stage. Perianal and urogenital infections are common causes of the disease but it can occur after artificial procedure on perineal area using by surgical instruments. It is mixed aerobic and anaerobic infection and E. coli is the most common causative bacteria. Untill now many investigators have focused on early diagnosis, preserving hemodynamic stability, broad-spectrum systemic antibiotics and treatment of underlying disease in management of Fournier's gangrene. The authors have experienced five patients of chronic liver disease whose necrotizing perineal infections developed spontaneously and treated them aggressively as described above and reconstructed perineal soft tissue defects using by various surgical methods, then we got good results both functionary and cosmetically. From now on, we would better reconstruct soft tissue defect of perineum with skin graft or pedicled flap in early stage when treat Fournier's gangrene, thereafter we can get an ultimate increase in patient's life quality.

Based on the soft and rigid extents, tissues are mainly divided into two groups in mammals, soft tissues including heart, lung, kidney and brain, and hard tissues including tendon, cartilage, teeth and bone. Among various tissues, bone, a dynamic rigid organ, is continuously remodeled by the opposing functional activity between bone formation by osteoblasts and bone destruction by osteoclasts. Bone protects the soft tissues and provides mineral reservoirs, which can supply the mineral needs of other soft tissues to normally maintain cellular function. While calcification in bone is an important action to fundamentally support the body and protect the soft tissues, calcification in soft tissues, including the heart, aorta, kidney, lung and spleen, results in severe organ damages, eventually causing sudden death. A growing body of evidence indicates that the osteoporotic patient who are aging, post-menopausal, diabetes and chronic kidney disease simultaneously represent a high clinical incidence of soft tissue calcification, illustrating a link between soft tissue calcification and bone decalcification (osteoporosis). This study will review what is currently known about the connection between bone decalcification and soft tissue calcification.

We present a case of a 37-year-old woman who had Kimura's disease involving the lower extremity mimicking malignant soft tissue mass. The diagnosis of Kimura's disease would be considered if there is a subcutaneous solid mass showing the preservation of the nodal architecture with perinodal infiltrations and the laboratory examinations for peripheral eosinophilia and serum IgE level should be recommended although it occurs at the lower extremity.

The artifacts in sonography is not always harmful. Sometimes it is beneficial for the evaluation of the water contents of the soft tissue and estimating the degree of inflammation and character of the regenerated tissue indirectly using artifacts such as acoustic shadowing and the enhanced transmission. It can also be useful to evaluate the possibility of aspiration of the calcifies masses by knowing of the contents of the water among them. Unlike the MRI it is useful to get real time informations with low cost in diagnosis and treatment of the soft tissue disease usinf artifacts in sonography.

Purpose: Mycobacterium abscessus belongs to the group of rapid-growing atypical mycobacterium. The organism is ubiquitous and is found in soil, dust, and water. Although it rarely causes disease in humans, Mycobacterium abscessus has been associated with soft tissue infection. To the best of our knowledge, this is the first case report of facial soft tissue Mycobacterium abscessus infection in a healthy child in Korea. Methods: A 12-year-old girl presented with an erythematous skin lesion with serous discharge on her chin, which had been present for 3 weeks. On her history, she had a laceration wound on her chin at public bath and the lesion was repaired at emergency department immediately. Although conventional soft tissue infecton treatment, her lesion remains unhealed state and had serous discharge for 2 months. Moreover, we found a 1 cm sized nodular mass on her chin. Therefore we performed excision operation and referred the specimen to the laboratory for microbial and histopathologic study. Results: Pathology report confirmed the mass was enlarged lymph node with chronic necrotizing granulomatous inflammation with central microabscess. Non-Tuberculous mycobacterium identification test through tissue specimen resulted Mycobacterium abscessus. We prescribed clarithromycin for three weeks by oral administration as well as performed wound debridement and mass excision via previous wound. This way, her lesion appeared to be complete healing with minimal scarring. There were no evidence of inflammation sign or palpable mass. Conclusion: Although the prevalence is rare, Mycobacterium abscessus infections of soft tissue should be considered even in a healthy child with a lesion caused by trauma or which fails to respond to conventional treatment.

Introduction: Soft-tissue impingement syndrome is now increasingly recognized as a significant cause of the chronic ankle pain. As a method to detect soft-tissue ankle impingement, a characteristic history and physical examination, routine MR imaging, and direct MR arthrography were used. The efficacy of routine MR imaging has been controversial for usefulness because of low sensitivity and specificity. Direct MR artrhography was recommaned for diagnosis because of the highest sensitivity, specificity and accuracy, but it requires an invasive procedure. The purpose of this study is to investigate the diagnostic accuracy of Fat suppressed, contrast enhanced, three-dimensional fast gradient recalled acquisition in the steady state with rediofrequency spoiling magnetic resonance imaging(CE 3D-FSPGR MRI) and to evaluate the clinical outcome of the arthroscopic treatment in assessing soft-tissue impingement associated with trauma of the ankle. Materials and Methods: We reviewed 38 patients who had arthroscopic evaluations and preoperative magnetic resonance imaging studies(3D-FSPGR MRI) for post-traumatic chronic ankle pain between January 2000 and August 2002. Among them, 24 patients had osteochondral lesion, lateral instability, loose body, malunion of lateral malleoli, and peroneal tendon dislocation. The patient group consisted of 23 men and 15 women with the average age of 34 years(16-81 years). The mean time interval from the initial trauma to the operation was 15.5 months(3 to 40 months), The mean follow-up duration of the assessment was 15.6months(12-48 months). MRI was simultaneously reviewed by two radiologists blinded to the clinical diagnosis. The sensitivity, specificity and accuracy of MRI was obtained from radiologic and arthroscopic finding. Arthroscopic debridement and additional operation for associated disease were performed. We used a standard protocol to evaluate patients before the operation and at follow-up which includes American Orthopedic Foot and Ankle Society Ankle-Hindfoot Score. Results: For the assessment of the synovitis and soft tissue impingement, fat suppressed CE 3D-FSPGR MR imaging had the sensitivity of 91.9%, the specificity of 84.4 and the accuracy of 87.5%. AOFAS Ankle-Hindfoot Score of preoperative state was 69.2, and the mean score of the last follow-up was 89.1. These were assessed as having 50% excellent(90-100) and 50% good(75-89). The presence of other associated disease didn't show the statistically significant difference(>0.05). Conclusion: Fat suppressed CE 3D-FSPGR MR imaging is useful method comparable to MR arthrography for diagnosis of synovitis or soft-tissue impingement, and arthroscopic debridement results in good clinical outcome.

Peripheral neuroepithelioma (PNE) of soft tissue is a malignant neuroectodermal tumor arising from peripheral (nonautonomic) nerve. It nay occur in both children and adults, and are highly aggressive neoplasms that rapidly give rise to metastatic disease and death. We exprienced a case of peripheral neuroepithelioma of soft tissue in the upper arm in a 18-year-old female. Cytologic features revealed small round cells with scanty cytoplasm occurring both singly and in clusters. The clusters frequently tended to form Homer-Wright rosettes. The cells had a round to oval nucleus with fine chromatin and inconspicuous nucleoli in a hemorrhagic background.

Craniofacial cleft is a rare disease, and has multiple variations with a wide spectrum of severity. Among several classification systems of craniofacial clefts, the Tessier classification is the most widely used because of its simplicity and treatment-oriented approach. We report the case of a Tessier number 3 cleft with wide soft tissue and skeletal defect that resulted in direct communication among the orbital, maxillary sinus, nasal, and oral cavities. We performed soft tissue reconstruction using the straight-line advanced release technique that was devised for unilateral cleft lip repair. The extension of the lateral mucosal and medial mucosal flaps, the turn over flap from the outward turning lower eyelid, and wide dissection around the orbicularis oris muscle enabled successful soft tissue reconstruction without complications. Through this case, we have proved that the straight-line advanced release technique can be applied to severe craniofacial cleft repair as well as unilateral cleft lip repair.

Purpose: Peri-implantitis, a clinical term describing the inflammatory process that affects the soft and hard tissues around an osseointegrated implant, may lead to peri-implant pocket formation and loss of supporting bone. However, this imprecise definition has resulted in a wide variation of the reported prevalence; ${\geq}10%$ of implants and 20% of patients over a 5- to 10-year period after implantation has been reported. The individual reporting of bone loss, bleeding on probing, pocket probing depth and inconsistent recording of results has led to this variation in the prevalence. Thus, a specific definition of peri-implantitis is needed. This paper describes the vast variation existing in the definition of peri-implantitis and suggests a logical way to record the degree and prevalence of the condition. The evaluation of bone loss must be made within the concept of natural physiological bony remodelling according to the initial peri-implant hard and soft tissue damage and actual definitive load of the implant. Therefore, the reason for bone loss must be determined as either a result of the individual osseous remodelling process or a response to infection. Methods: The most current Papers and Consensus of Opinion describing peri-implantitis are presented to illustrate the dilemma that periodontologists and implant surgeons are faced with when diagnosing the degree of the disease process and the necessary treatment regime that will be required. Results: The treatment of peri-implantitis should be determined by its severity. A case of advanced peri-implantitis is at risk of extreme implant exposure that results in a loss of soft tissue morphology and keratinized gingival tissue. Conclusions: Loss of bone at the implant surface may lead to loss of bone at any adjacent natural teeth or implants. Thus, if early detection of peri-implantitis has not occurred and the disease process progresses to advanced peri-implantitis, the compromised hard and soft tissues will require extensive, skill-sensitive regenerative procedures, including implantotomy, established periodontal regenerative techniques and alternative osteotomy sites.

Gastric cancer continues to be a leading cause of cancer death. The majority of patients with gastric adenocarcinoma in China present with advanced disease. Ruling out unresectable cancers from an unnecessary "open" exploration is very important. The aim of this study was to assess the value of five-port anatomical laparoscopic exploration in T4 gastric cancer in comparison with three-port laparoscopic exploration and laparotomy exploration. We conducted a retrospective study on 126 patients with T4 stage scheduled for D2 curative gastrectomy based on computed tomography (CT) staging at Department of Gastric Cancer and Soft Tissue Sarcoma, Fudan University Shanghai Cancer Center, from Apr. 2011 to Apr. 2013. Laparotomy exploration (Group I), three-port laparoscopic exploration (Group II) or five-port anatomical laparoscopic exploration (Group III) were performed prior to radical gastrectomy. Accuracy rate for feasibility of D2 curative gastrectomy in laparotomy exploration and five-port anatomical laparoscopic exploration groups was higher than that in the three-port laparoscopic exploration group. Five-port anatomical laparoscopic exploration group had the highest accuracy resection rate (Group I vs Group II vs Group III,92.6% vs78.6% vs 97.7%; p<0.05) and shorter length of hospitalization (Group I vs Group II vs Group III, $9.58{\pm}4.17$ vs $6.13{\pm}2.85$ vs $5.00{\pm}1.81$; p<0.001). Three-port laparoscopic exploration has low accuracy rate for assessing feasibility of D2 curative gastrectomy and five-port anatomical laparoscopic exploration should be performed on patients with T4 gastric cancer.
