목적: 최근 자기공명영상의 개발로 다양한 연조직종양의 영상의학적 진단이 가능해 졌다. 그러나 연조직종양의 다양한 조직구성이나 시간에 따라 구성분의 변화는 자기공명영상 만으로 악성과 양성 종양조차 감별을 어렵게 한다. 이에 본 저자들은 임상과 자기공명영상의 복합적인 소견으로 악성과 양성 연조직종양을 감별해 보고자 하였다. 대상 및 방법: 병리조직학적으로 확진된 82례(중간성종양을 악성종양으로 포함하여 37례와 염증성 종괴를 양성종양으로 포함하여 45례)를 후향적으로, 임상적 소견으로 연령, 크기, 위치, 그리고 자기공명영상 소견으로 종양경계, T2신호강도양상, 조영제T1신호강도양상, 그리고 조영증강 범위를 연관시켜 분석하였다. 자기공명영상으로 진단이 어렵지 않는 많은 전형적인 지방종과 결절종 그리고 농양같은 낭종은 양성종양 분류에서 제외하였다. 결과: 악성연조직종양은 양성에 비하여 연령으로 21~40세와 61~80세, 크기로 3.0 cm 이상, 발생위치로 몸체-골반-하지, 그리고 자기공명영상에서 불규칙한 경계, 50%이상의 조영증강범위 소견들의 빈도가 높았다. 결론: 발생위치로 몸체-골반-하지 와 상지-어깨-척추 로 나눈 임상소견이 악성과 양성 연조직종양을 감별하는데 통계학적으로 유의성있는 차이를 보였으며 나머지 다른 소견들은 특이적이지는 않았지만 부가적으로 악성과 양성을 감별하는데 도움이 되는 소견이었다.

Purpose: Malignant soft tissue tumors, known as sarcomas, are well known to be locally aggressive, frequently metastatic, and highly recurrent. In other hands, intermediate soft tissue tumors often recur locally with adjacent tissue infiltration so the clinical management is difficult as sarcoma. In the present study, we evaluate the clinical course of the intermediate soft tissue tumors and consider the management plan for those. Methods: From March, 1998 to April 2008, total 3 patients of intermediate soft tissue tumors underwent operations. A patient with fibrohistiocytic neoplasm, a free flap reconstruction was performed, and he underwent several more operations because of recurrences. Other patients with desmoids - type fibromatosis showed local invasion and adhesion, and one of them underwent reoperation due to local recurrence. Results: 2 of 3 patients underwent recurrences of tumors and reoperations were performed. In another patient with no recurrence, follow-up period was just 5 months, so there may be recurrence of tumor in long term follow-up. Conclusion: The clinical course of intermediate soft tissue tumors shows high recurrence rate. So clinically, intermediate soft tissue tumors should be considered as sarcomas. The successful management requires wide resection, carefully planned reconstruction, and close follow up with radiologic evaluation.

A 65-year-old woman presented with a solid mass on the right temporal area. The mass had grown for over 2 years without any initiating event of trauma or inflammation. Before excision, the patient went through a computed tomography scan, revealing a calcified mass without bony connection. Under general anesthesia, an excisional biopsy was performed. Microscopic examination confirmed a diagnosis of soft tissue osteoma. Soft tissue osteoma is rare, especially in the head and neck region. Osteomas in the temporal region have not been reported yet. Due to its rarity, osteoma might be misdiagnosed as another soft tissue or bone origin tumor. Its treatment of choice is simple excision. In this review, we present an unusual clinical form of soft tissue osteoma.

Extraosseous Ewing's sarcoma is a rare primary malignant soft tissue tumor which is histologically identical to Ewing's sarcoma. This tumor tends to involve the soft tissue of the lower extremity and paravertebral region of adolescents and young adults but particularly rare in infants. We recently experienced a case of extraosseous Ewing's sarcoma which presented in the left arm of 4 months infant.

Primary neoplasms of the ribs and sternum are rare. Most primary bony chest wall neoplasms are malignant, and chondrosarcoma is the most common malignancy in this location The etiology of chondrosarcoma is unknown. Definitive diagnosis of chondrosarcoma can only be made pathologically. The natural history of chest wall chondrosarcoma is one of slow growth and local recurrence. Most tumors of the sternum require wide resection and reconstruction procedures, with potentially serious postoperative problems. Advances in chest wall reconstruction primarily through refinement in muscle transposition and clarification of the functional anatomy and blood supply of trunk muscles, has resulted in a more aggressive resection of the these tumors . Recently we experienced a case with chondrosarcoma of the sternum. A 56 year-old man was admitted to our hospital due to painless, slowly enlarging mass at the left sternoclavicular junctional area. The chest radiograph strongly suggested an underlying cartilaginous neoplasm owing to the appearance of typical flocculent and curvilinear calcifications within the lesion. On CT of the chest, the tumor exhibited a scalloped or lobulated contour, hypodensity of the nonmineralized component in comparison to adjacent muscle, and characteristic stippled cartilaginous matrix mineralization, also typical for cartilaginous neoplasm. The patient underwent wide resection of the chest wall tumor include with a 2-3cm margin of normal tissue on all sides and the thoracic skeletal defect was reconstructed with polytetrafluoroethylene [Gore-Tex] soft-tissue patch. Soft tissue reconstructive procedure was done with the pectoralis major muscle transposition. The patient had an uneventful postoperative course and discharged without adjuvant treatment such as radiation and chemotherapy.

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.

Reconstruction of oral soft-tissue defects following resection of oral carcinomas can be achieved using various techniques including microsurgical tissue transfer. However, there seems to be a role for regional or local flaps. Small to medium-size defects can be functionally reconstructed with the platysma myocutaneous flap as an excellent choice particularly in medically compromised patients not being eligible for free tissue transfer. The present paper reviews the indication, surgical technique, and complications following reconstruction of defects of the oral cavity with the platysma myocutaneous flap.

Background: Soft-tissue sarcomas require tailored and multidisciplinary treatment and management. However, little is known about how sarcomas are treated and managed throughout the Asia-Pacific region. Materials and Methods: MEDLINE was systematically searched using prespecified criteria. Publications (previous 10 years) that reported tumour characteristics, treatment patterns, survival outcomes, and/or safety outcomes of patients with soft-tissue sarcoma were selected. Exclusion criteria were studies of patients <18 years of age; ${\leq}10$ patients; countries other than Australia, Hong Kong, Indonesia, Korea, Malaysia, New Zealand, Philippines, Singapore, Taiwan, or Thailand; >20% benign tumours; sarcomas located in bones or joints; gastrointestinal stromal tumour; Kaposi's sarcoma; or not reporting relevant outcomes. Results: Of the 1,822 publications retrieved, 35 (32 studies) were included. Nearly all patients (98%, 1,992/2,024; 31 studies) were treated with surgery, and more studies used adjuvant radiotherapy than chemotherapy (24 vs 17 studies). Survival outcomes and recurrence rates varied among the studies because of the different histotypes, sites, and disease stages assessed. Only 5 studies reported safety findings. Conclusions: These findings highlight the lack of specific data available about soft-tissue sarcomas in the Asia-Pacific region. Better efforts to understand how the sarcoma is managed and treated will help improve patient outcomes in the region.

A 17-month-old boy was evaluated for a midline mass on his chin. The mass was anchored to the mentalis muscle with a stalk-like structure. The pathological diagnosis of the mass was rhabdomyomatous mesenchymal hamartoma. This is the first report of rhabdomyomatous mesenchymal hamartoma presenting as a midline chin mass in Korean pediatric patients.

저등급의 섬유점액성 육종은 최근에야 진단적 분류가 이루어진, 드문 연부 조직 종양이다. 젊은 성인의 심부연부 조직에서 발생하는 경향이 있으며, 국소 재발이나 원격 전이가 가능하다. 진단적 범주가 확실히 정립되어 있지 않고 특정한 질환명으로 구분되고 있지 않다. 조직학적으로, 주로 소용돌이 양상으로 자라는 방추상세포와 점액성이나 섬유성 기질이 번갈아 관찰되는 것이 특징이다. 형태학적이나 면역조직학적 특징에 대한 세심한 고려가 상기 질환의 진단에 도움이 되며, 다른 양성이나 악성 연부 조직 종양과의 감별에 도움이 된다. 흉백에 발생한 저등급의 섬유점액성 육종을 경험하였기에, 문헌 고찰과 함께 보고하는 바이다.
