The thymolipoma is rather rare benign tumor of the thymus. One case of huge thymolipoma, seen in a 11-year-old boy, is presented. It is about 2.16kg. He had some chest discomfort. The chest film showed homogeneous haziness fills the left hemithorax, On chest CT scan, multiple small amorphous soft tissue densities were recognized as islands within a large fatty mass. Tumor resection was performed through left anterolateral thoracotomy. The mass was yellowish soft, measured 29x19Xllcm, 12X7.5x3.5cm, 7.0X3.0X1.0cm. Microscopically, the tumor was comprised of abundant mature adipose tissue and normal thymic tissue.

From January 1994 to August 1995 we performed 270 cases of fine needle aspiration cytology for bone and soft tissue lesions. Among them 137 cases were diagnosed histologically. Sixty-seven cases were benign and 70 cases were malignant. We analysed these on the aspect of sensitivity, specifity, positive predictive value, negative predictive value of the cytologic examination. Malignant cases consisted of bone tumor 29 cases; soft tissue tumor 25 cases; and metastatic tumor 16 cases. The sensitivity and specifity of the aspiration cytology for malignant tumor were 67.8% and 97%, respectively. The positive and negative predictive value of aspiration cytology were 97.4% and 72.7%, respectively. Among them 40 cases were primary bony lesions; 14 benign lesions, 26 malignamt bone tumors. Sensitivity of aspiration cytology for these primary bony lesion was 90%(18/20) and its specifity was 100%(13/13). Three cases showed atypical cells in cytology but with biopsy we could find them as one benign and two malignancies. Two cases of manignancy showed negative result in cytology; one was parosteal sarcoma of proximal femur and the other was osteosarcoma of proximal tibia which was biopsied already at other hospital. Although the overall sensitivity and specifity for malignant bone and soft tissue tumors were relatively low and not so predictable, the fine needle aspiration cytology for primary bony lesion was useful in the differential diagnosis of benign or malignancy.

We experienced a case of soft tissue osteochondroma in the foot. The 43-years-old male was complained palpable mass and mild pain at the heel for 3 years. The plain radiograpy revealed a bony mass without connection of neighbor bone in the heel. The osteochondroma in the soft tissue is rare benign tumor. The mass was removed en bloc. The gross and histologic findings were consistent with osteochondroma. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, soft tissue osteochondroma, and true osteochondroma which arises from bone. The symptom was improved. After postoperative 1 year, recurrence was not.

Pleomorphic adenoma is a benign salivary gland tumor with histologic diversity. The majority of these tumor occurs in the parotid gland. The authors experienced the patients, who complained the tumor-like soft tissue mass on the palatal area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed it as pleomorphic adenoma in the palatal area, and obtained characteristic features were as follows: 1. Main clinical symptom was a painless, slow growing, soft tissue mass with normal intact overlying mucosa on the palatal area. 2. In the radiographic examminations, well encapsulated homogeneous soft tissue mass was shown in the lesion site, and cortical thinning on the palate was also observed. 3. In histopathologic examminations, proliferated cellular components in the hyaline stroma were observed as double layered duct-like structure and densely solid sheet appearance.

Thallium-201 scintigraphy is used to discriminate the malignant bone tumor from the benign by qualitatively and quantitatively, and to predict the response of preoperative chemotherapy in osteosarcoma, by comparing the changes of thallium uptake ratio after chemotherapy to the tumor necrosis ratio. Thallium-201 scintigraphy scan should be done prior to surgical biopsy. PICKER Prism 2000 gamma camera with high resolution parallel hole collimator is usually used for scanning. The patient is injected with 2-3mCi of Tl-201 and the early phase is checked in 30 minutes and delayed phase in 3 hours. The scan images are visually evaluated by a blinded nuclear medicine physician. We could evaluate true positive, true negative, false positive and false negative by the comparison of results with those of biopsy, and calculate positive and negative predictive value(%), sensitivity(%), specificity(%) and diagnostic accuracy(%). For the quantitative analysis of thallium uptake, we drew the region of interest on the tumor side and contralateral normal side as mirror image, and calculated the uptake ratio with dividing the amount of gamma count in tumor side by normal side. We could calculate the percent changes of thallium uptake ratio in early and delayed phase, and compare them to the ratio of tumor necrosis. Thallium-201 scintigraphy proved as useful imaging study to discriminate malignant bone tumor from benign, but had exception in giant cell tumor and low grade malignant bone tumors. We can use T1-201 scan to differentiate the benign from the malignant tumor, and to evaluate the response of preoperative chemotherapy or radiotherapy, and to determine the residual tumor or local recurrence. For the better result, we need to have a more detail information about false positive cases and a more objective and quantitative reading technique.

Primary tumors of the chest wall are rare than those of other portions of the body. Soft tissue tumors of the chest wall, though these are benign or malignant, should not be paid special attentions about their management than other soft tissue tumors of the body. Thoracic skeletal tumors, however, have some problems in the treatment because of defect in chest wall leading to herniation of lung and paradoxical movement of thoracic cage. The authors experienced 10 case of primary chest wall tumors at the department of thoracic and cardiovascular surgery, the national medical center, during last 15 years. Five of 10 cases were soft tissue tumors, and they were 2 case of lipoma and each one case of myxosarcoma and leiomyosarcoma. Among 5 bone tumors there no cases of sternal tumor, and their histopathological diagnosis were each one of fibrous dysplasia, giant cell tumor, osteochondroma, Ewing`s sarcoma and osteogenic sarcoma. Wide excision, though it was palliative one in certain case, was performed in 9 cases and only diagnostic incisional biopsy in one case, There were no postoperative deaths during admission to the hospital and all cases were missed during short term follow up after discharge from the hospital.

골격외 연골종은 골이나 골막과의 연결이 없이 초자연골을 주성분으로 하는 연부조직의 연골종양을 이른다. 골격외 연골종은 매우 드물게 발병하며, 대부분 수부나 족부의 관절근처의 연부조직 및 건 활액막 근처에서 흔하게 관찰된다. 본 증례에서는 저자들이 경험한 젊은 여성의 수지에서 발생한 골격외 연골종 1예를 보고하고자 한다.

목적 : 족부 및 족관절에 발생하는 종양은 다른 부위에 비해 그 발생 빈도가 낮으며, 특히 악성 종양은 매우 드물고 양성 종양으로 간과되는 경우도 있어 족부 및 족관절에 발생한 종양의 임상 양상에 대해 알아보고자 하였다. 대상 및 방법 : 1989년부터 1998년까지 10년 동안 족부 종양으로 진단받은 72명을 대상으로 조사를 시행하였다. 결과 : 남자가 40예, 여자가 32예였다. 양성 종양이 53예(74%)로, 연부 조직 종양이 30예, 골 종양이 23예였다. 악성 종양은 19예(26%)였으며, 연부조직 종양이 17예, 원발성 골종양이 1예, 전이성 골종양이 1예였다. 양성 종양은 연부 조직에서는 섬유종이, 골종양에서는 골연골종이 가장 많았다. 악성 종양은 악성 흑색종이 7예로 가장 많았다. 호발 부위는 양성종양의 경우 족지부, 악성 종양의 경우 발 뒤꿈치 부위였다. 악성 종양 19예 중 국소 재발은 3예, 원격 전이는 8예에서 발생하였다. 결론 : 악성 종양이 26%였으며 원격 전이가 42%로 높았다. 따라서, 족부 종양의 경우 악성의 가능성을 염두에 두고, 치료 시에 병리학적인 확진이 필수적이라 하겠다.

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.
