  • Alveolar soft part sarcoma, named by Christopherson in 1952, is a very rare soft tissue sarcoma. It reportedly accounts for 0.5 to 1.0% of all soft tissue sarcoma and no established treatment principle assists it. The relative lack of symptoms makes it easily overlooked and consequently early diagnosis is frequently impossible. Often, the metastasis to the lung or the brain is the first manifestation of the disease. In some cases wide excision is not performed because it is misdiagnosed as a benign tumor. Authors experienced 7 cases of alveolar soft part sarcoma in 20 years and found the ultimate prognosis grave and the treatment not promising. Therefore, the authors recommend the following; 1. Early diagnosis and early treatment are important for successful management of alveolar soft part sarcoma. 2. Preoperative incisional biopsy is necessary for pathologic diagnosis. 3. The recommended treatment modality is a combination of wide excision, chemotherapy and radiotherapy.

  • FDG-PET의 반정량적인 당대사지표인 pSUV, aSUV, $TBR_{51}$$TBR_{area}$는 비관혈적으로 악성과 양성 연부조직 병변을 감별하는 데 모두 높은 정확도를 나타내었다. FDG-PET은 연부조직 종양의 평가에서 MRI와 상호보완적인 역할을 할 수 있을 것이다. 또한 FDG-PET은 악성 연부조직 종양환자들의 전이의 발견과 치료 후 추적관찰에도 도움이 될 것으로 생각되며 이에 관한 연구가 계속되어야 할 것이다.

  • 사지와 몸통의 연부조직 종양은 정형외과 의사가 직면할 수 있는 흔한 문제이다. 비록 연부조직 종양은 대부분 양성이지만 정형외과 의사는 양성과 악성 종양을 구별할 수 있는 특징을 알고 있어야 한다. 연부조직 종양의 임상적 특징 및 역학을 이해하게 되면 올바른 진단 및 수술적인 치료를 할 수 있게 된다. 종양의 크기와 깊이는 종양의 진단을 위해 가장 중요한 요소이다. 종양의 감별 진단을 하기 위해서 우선적으로 상세한 병력청취와 자세한 신체 검사가 필요하며, 이후 단순 방사선 촬영, 초음파, 자기공명영상(magnetic resonance imaging), 양전자 방출 단층촬영술(positron emission tomography), 컴퓨터 단층촬영(computed tomography), 뼈 스캔, 혈관 조영술 등의 다양한 영상 촬영법을 사용하여 종양을 진단하고 진단된 종양의 특성을 확인하여야 한다. 특히 초음파 검사는 외래에서도 쉽게 수행할 수 있어 유용하다. 그러나 검사자의 숙련도에 따라 검사 정확도의 차이가 발생할 수 있다는 단점이 있다. 종양의 생검을 통한 조직검사는 종양에 대한 모든 영상 검사를 시행한 후 최종적으로 시행하는 것이 원칙이다. 조직 검사를 시행할 때는 세심한 주의를 기울여야 하며, 최종적인 진단 후에는 치료를 위해 다각적인 접근을 시행하여야 하며 필요한 경우에는 경험 있는 근골격계 종양전문의사에게 의뢰하는 것이 필요하다.

  • Aggressive angiomyxoma is a rare neoplasm that arise from soft tissue of the perineum and usually affects young woman. It has a high risk of local recurrence due to infiltrative lesion. This tumor should be distinguished from benign and malignant tumor or tumor like lesion of the perineum. We experienced a case of an aggressive angiomyxoma on soft tissue of the vaginal wall in 43-year-old woman and reported it with a brief review of literature.

  • Recently we experienced four cases of soft tissue Ewing sarcoma, developed in the calf muscles in two cases, and one case each in the foot and suprascapular region. We also found that the clinical course in all cases was rather rapid, because of local recurrence and metastatic lesions developing within a few months, followed by the patients' death in about 2 years after the primary tumor was excised. These cases were improperly treated initially as some kind of benign soft tissue tumor. The delay led to missed early accurate diagnosis and was thought to be one of the main causes for the rapid local recurrence and metastasis after tumor excision. The pulmonary metastasis was the most common cause of death.

  • Myofibroma is a rare benign soft tissue tumor that in all ages usually occurs in the head and neck region, and at subcutaneous tissue, but rarely has bone origin within bone. Intraosseous lesions are more often found in childhood. Although intraosseous lesions are relatively common in mandible. Reports for mandible, reports on radiographic findings of myofibroma occurred on the mandible are uncommon. We describe the radiographic appearance on the conventional radiographs and CT of myofibroma of the mandible in a 9-year-old boy. This benign lesion closely resembles to odontogenic cyst or tumor on image.

  • Giant cell tumor of the tendon sheath (GCTTS) is a slowly growing, benign soft tissue tumor. The tumors occur predominantly on the hands and feet. Although the clinical and histopathologic features are well-defined, only a few reports have described the cytologic appearance of this entity. A 26-year-old woman presented with a gradually developing circumscribed soft tissue mass near the proximal phalanx of her left little finger for one year. Imprint and fine needle aspiration (FNA) smears were obtained from the excisional biopsy specimen. The imprint smears were composed of predominantly singly dispersed bland mononuclear cells and several giant cells. The mononuclear cells were polygonal to round, and they showed a histiocyte-like appearance. Osteoclast-type multinucleated giant cells of various sizes were randomly scattered throughout the smears, and these cells contained 3 to 50 nuclei. Nuclear atypia and pleomorphism were absent in both the single and giant cells. Loose aggregates of hemosiderin-laden macrophages and binuclear stromal cells were also seen. The cytologic features of the FNA smears were similar with those of the imprint, Additionally, the FNA smears contained several clumps of densely collagenous stromal tissue that were seldom noted in previously reported cytologic material. The cytologic features were well-correlated with the concurrent histologic findings and the diagnosis of GCTTS was made. When the clinical and radiologic datas are integrated, the diagnosis of GCTTS can be strongly suggested, based on the pre-operative cytologic specimen.

  • Soft tissue implantation of thyroid tissue is a very rare event. Needle tract implantation of thyroid carcinoma after fine-needle aspiration (FNA) biopsy has been occasionally reported, but implantation of benign thyroid tumor tissue is extremely rare. Rupture of thyroid tissues during surgery or trauma may cause the thyroid tissue to be implanted and result in multiple palpable nodules in soft tissue of the neck. Several reports have shown the possibility of implantation of normal or hyperplastic thyroid tissues in soft tissue. We herein report a case of implantation of adenomatous hyperplastic tissue in the neck along the trochar and previous operation site after endoscopic thyroid surgery, which was successfully treated by complete excision.

  • Purpose: Elastofibroma is a rare benign tumor that is characterized histologically by the presence of abnormal elastic fibers within a stroma of fibroadipose tissue. Usually it is slow-growing, solid, ill-defined mass occurring chiefly in elderly woman and arising from the soft tissue around the inferior angle of the scapula. Methods: We experienced a representative case of elastofibroma. A 73-year-old women complained of a soft-tissue mass, which measured $6{\times}6cm$, at the inferior angle of the left scapula, which had been found incidentally 4 months before. When the arm was elevated, the mass projected out beneath the scapula. The entire mass was resected with a tumor-free margin. Results: The resected tumor appeared to be nonencapsulated, fibrous and white mass, and it contained yellow fatty streaks. We confirmed that the histopathologic diagnosis of this tumor was elastofibroma. Follow-up examination revealed no evidence of local recurrence for 10 months. Conclusion: This entity is rarely reported in Korea. However, more patients could be diagnosed if physicians pay more careful attention to clinical and radiological features of elastofibroma. Moreover, recognizing the benign nature of this lesion is important to avoid an unnecessary operation.

  • 초음파의 다양한 장점에도 불구하고 초음파의 질감(echotexture)과 균질성(homogenecity)의 문제로 악성 종양과 양성종양을 감별하는데 한계가 있을 수 있으므로, 초음파를 이용한 고형의 연부조직 종괴를 진단할 때는 주의가 필요하다.
