An 11-year-old spayed female maltese was presented for abdominal distention, dysuria and dyschezia. Panting and heart murmur was found and abdominal palpation was difficult due to increased abdominal pressure. A soft tissue mass, $6{\times}3cm$ in size, was identified radiographically in pelvic canal, displacing the descending colon to the medioventral direction and the urinary bladder cranially. On ultrasonography, the mass consisted of homogeneous hypoechoic parenchyma containing the focal hyperechoic region ($1.6{\times}1.5cm$). The mass had distinct margin and no connection with adjacent organs. It was considered as a mass originating from the retroperitoneal cavity. Additional diagnostic procedures were not advanced because of the owner's request, and only a surgical excision of the mass was performed to alleviate the dysuria and dyschezia. Histopathologic examination and immunohistochemistry determined the mass as a soft tissue sarcoma and excluded hemangiosarcoma and osteosarcoma, both are the most common types of the retroperitoneal tumors. This report described non-vascular soft tissue sarcoma originating from the retroperitoneal cavity in a maltese dog.

Many different factors which may affect the prognosis of the soft tissue sarcomas have been reported by many authors ; Generally, tumor size, histologic type, surgical margin, and multi modality therapy therapy as the prognostic factors were reported. The objectives of this retrospective study of soft tissue sarcomas are : 1) to define more clearly prognostic variables that have significant predictive value for disease-free and overall survival ; and 2) to evaluate tumor histologic grade based upon extent of tumor necrosis as a means of stratifying more aggressive soft tissue sarcomas(grade II & III) of the extremities. We treated 94 patients who had soft tissue sarcoma of the extremities and trunk from May 1984 to September 1994(average duration of follow-up was 5 years ranging from 2 months to 10 years) and evaluated the prognostic factors of the soft tissue sarcomas; age, sex, depth, size, location, histologic type and grade, stage, therapy modality, surgical margin, local recurrence and distant metastasis. The results were as follows. 1. The patients with poorer prognosis were over the age of fifty, whose mass was deeply located, size of the mass was over 10cm in diameter, grade III in histology, who had local recurrence, metastasis, and received only surgery. 2. Among these prognostic factors, the most significant prognostic factor was histologic grade base upon extent of tumor necrosis.

목적: 골외성 골육종은 고악성도 종양으로 연부조직육종에 비해 어느 정도의 치료 성적을 보이는 지에 대해 잘 알려져 있지 않다. 본 연구는 두 악성 연부 육종의 치료결과를 비교 하는데 있다. 대상 및 방법: 병리학적으로 확진된 12례의 골외성 골육종의 치료결과를 분석하였다. 고악성도 연부조직육종 환자와 짝짓기 환자-대조군 분석을 위해 악성도 3등급의 연부조직 육종 중 골외성 골육종 환자와 유사한 위치, 크기, 나이를 가진 환자 6배수를 선별하였다. 결과: 골외성 골육종 환자 나이는 35~77세 (중간값 50세)였다. 위치는 상지 5례, 둔부 4례, 하지 3례 였다. 5년 생존율은 52% 였다. 대조군인 연부조직육종의 5년 생존율은 55%로 두 군 사이에 유의한 차이는 없었다(p=0.8). 국소재발율은 골외성 골육종이 58%, 연부조직육종이 36%이었으며 두 군 사이에 유의한 차이는 없었다(p=0.2). 전이율은 각각 67%, 51%이었으며 유의한 차이는 없었다(p=0.4). 결론: 골외성 골육종은 고악성도 연부조직종양과 비슷한 전이 및 국소재발 위험도를 가지는 것으로 보인다. 그러나 본 연구에 포함된 골외성 골육종의 증례가 적으므로 다기관 연구를 통해 더 연구가 필요할 것으로 생각된다.

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.

Purpose: Local recurrence is the most common cause of failure in retroperitoneal soft tissue sarcoma patients after surgical resection. Postoperative radiotherapy (PORT) is infrequently used due to its high complication risk. We investigated the efficacy of PORT using modern techniques in patients with retroperitoneal soft tissue sarcoma. Materials and Methods: Eighty patients, who underwent surgical resection for non-metastatic primary retroperitoneal soft tissue sarcoma at the Yonsei Cancer Center between 1994 and 2015, were retrospectively reviewed. Thirty-eight (47.5%) patients received PORT: three-dimensional conformal radiotherapy in 29 and intensity-modulated radiotherapy in nine patients. Local failure-free survival (LFFS), overall survival (OS), and RT-related toxicities were investigated. Results: Median follow-up was 37.1 months (range, 5.8-207.9). Treatment failure occurred in 47 (58.8%) patients including local recurrence in 33 (41.3%), distant metastasis in eight (10%), and both occurred in six (7.5%) patients. The 2-year and 5-year LFFS rates were 63.9% and 47.9%, respectively. The 2-year and 5-year OS rates were 87.5% and 71.1%. The 5-year LFFS rate was significantly higher in PORT group than in no-PORT group (74.2% vs. 24.3%, p<0.001). In multivariate analysis, PORT was the only independent prognostic factor for LFFS. However, there was no significant correlation between RT dose and LFFS. OS showed no significant difference between the two groups. Grade ${\leq}2$ acute toxicities were observed in 63% of patients, but no acute toxicity ${\geq}$ grade 3 was observed. Conclusion: PORT using modern technique markedly reduced local recurrence in retroperitoneal sarcoma patients, with low toxicity. The optimal RT technique, in terms of RT dose and target volume, should be further investigated.

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.

초음파 검사는 연부조직 종물 평가를 위해서 일차적으로 시행할 수 있는 효과적인 검사로 알려져 있다. 저자들은 좌측원위 대퇴부에 통증을 동반한 표재성 연부조직 종물로 내원한 환자의 초음파 검사에서 양성 종양으로 판단되었으나 수술 후 조직검사에서 활막육종으로 진단된 증례를 경험하여 문헌고찰과 함께 이를 보고하고자 한다.

Synovial sarcoma is a malignant soft tissue tumor originated from primitive mesenchymal cell. It occurs primarily in the paraarticular regions, parapharyngeal regions and abdominal wall. We experienced a case of intrapulmonary synovial sarcoma which was the first case originated from the lung and confirmed postoperatively.

The Ewing`s sarcoma is the primary malignant bone tumor but the tumor also occurs as a primary soft tissue neoplasm without involvement of bone. Here is presented a case of extraskeletal Ewing`s sarcoma in the posterior and superior mediastinum with review of literature. To our knowledge, this is the first case report of extraskeletal Ewing`s sarcoma in Korea.

Epithelioid sarcoma is a malignant soft tissue neoplasm with an uncertain histogenesis. We report the imprint cytologic features of epithelioid sarcoma in the left shoulder of a 29-year-old male patient. Imprint cytologic findings showed dissociated and loose aggregates of anaplastic epithelioid cells on the necrotic, bloody, and inflammatory background. Tumor cells were round to polygonal shaped. Tumor cells had vesicular nuclei with abundant cytoplasm. The nuclei were irregular in shape and often eccentrically located. Some tumor cells were oval to spindle shaped. Binucleated and multinucleated cells were found. Intracytoplasmic vacuoles were present. On immunohistochemical stain, the tumor cells were positive for epithelial membrane antigen, vimentin, and CD34.
