본 논문에서는 지방종 초음파 영상에서 지방종을 자동적으로 추출하는 방법을 제안한다. 제안된 방법은 초음파 영상에 Monotone Cubic Spline 보간법을 이용하여 ROI영역을 추출한다. 추출된 ROI 영역에 Fuzzy Stretching 기법을 적용하여 명암 대비를 강조한 후, ART2 알고리즘과 8방향 윤곽선 추적 알고리즘을 적용하여 잡음을 제거한 후에 지방종의 후보 영역을 추출한다. 추출된 지방종의 후보 영역 중에서 형태학적으로 타원 형태를 띠거나 가장 큰 후보 영역의 정보를 이용하여 Labeling 기법을 적용하여 최종적으로 지방종 영역을 추출한다. 제안된 방법을 지방종 초음파 영상에 실험한 결과, 지방종 영역이 비교적 정확히 추출되는 것을 실험을 통하여 확인하였다.

Lipoma is a circumscribed mesenchymal tumor originating from the adipose tissue. The lesion is usually small and asymptomatic. The most common location is in the neck region, however, lipoma can be found in the mediastinum in rare occasions. Although lipoma reach to the large proportions in the mediastinum, it rarely compresses the neurovascular structure. We present a case of a 58-year-old man, in which a hourglass-type cervicomediastinal lipoma produced Horner's syndrome with voice change. The man presented a swelling at the right side of his neck, ptosis and anhidrosis on the right side of his face, and right chest discomfort. After the removal of the mass, all the symptoms which had been provoked by compression, as well as Horner's syndrome and hoarseness, nearly disappeared.

Lipoma is a benign tumor composed of mature adipocytes and the most common soft tissue mesenchymal neoplasm but relatively rare in the oral cavity. Lipoma of the tongue is uncommon and especially multiple lipomas are quite rare and only several cases of those were reported. We describe an unusual case of multiple lipomas of the tongue.

Although lipoma is the most common soft-tissue tumor, accounting for up to one half of all soft-tissue tumors, intra-articular synovial lipomas are rarely seen. Occasional cases of intra-articular lipoma arborescens have been reported. However, true intra-articular synovial lipomas should be differentiated from other similar lipomatoid conditions such as lipoma arborescens, which are different pathologic entities and show different clinical presentations. This article presents the case of a patient who had an intra-articular synovial lipoma of the knee joint.

Purpose: This study was designed to know the usefulness of the MRI to distinguish lipoma and well differentiated liposarcoma (WDL). Materials and methods: 47 lipomatous tumors with MRI were reviewed among the 107 lipomatous tumors operated in our department. MRI examinations and their corresponding pathology reports were compared to determine sensitivity, specificity, diagnostic ability, positive predictable value and negative predictable value. Statistical analysis was performed to know the relationship between malignancy of the tumor (WDL) with the age and gender of the patients, and location, depth, size and the enhancement of tumors in MRI. Results: Among 28 lipoma in MRI examinations, 26 were proved as lipoma in pathology, and only 6 were WDL from 19 suspicious lesions in MRI, and others were proved as lipoma variants mostly. The varieties of lipoma variants were fibrolipoma, angiolipoma, spindle cell lipoma, lipoblastoma and angiomyolipoma. The sensitivity, specificity, diagnostic ability, positive predictable value and negative predictable value of MRI were 100%, 68 %, 72%, 31% and 100% in WDL, and 90%, 89%, 89%, 93% and 84% in lipoma. Among the variants to distinguish WDL and lipoma, the size of tumor and enhancement in MRI were significant statistically (p<0.05). Conclusion: MRI was highly sensitive in detection of WDL and highly specific in detection of simple lipoma. The size of tumor and enhancement in MRI were significant variants to distinguish WDL and lipoma. When MRI finding is non-specific, it is more likely to represent one of lipoma variants.

Parosteal lipoma is a rare type of lipoma, the incidence being approximately 0.3% of all lipomas. Moreover, parosteal lipoma coexisting with osteochondroma is extremely rare. A few cases with coexistence of osteochondroma and parosteal lipoma have been reported and they were thought to be reactive changes of adjacent bone by parosteal lipoma. However, temporal relationship of these tumors could not be explained. Here, we report a case of parosteal lipoma associated with osteochondroma of the right ilium developed over 6 years, with follow-up radiographs.

Lipomas are the commonest soft tissue tumor. However, those arsing in the hand are infrequent. Lipomas in the hand that exhibit a size of more than 5 cm call giant lipoma, these are very rare only case reports and small series of this entity have been described. We could experience a case about giant lipoma of the hand which cannot easily contact, we report a case including review of literatures.

The parosteal lipoma is a very rare benign neoplasm of adipose tissue having an intimate relationship to the periosteum. The parosteal lipomas comprise only 0.3% of all lipomas. We have experienced a parosteal lipoma with hyperostosis of the left tibia, in 52 years old male. We report a case of parosteal lipoma and its clinical feature with review of the literature.

Spindle cell lipoma is a relatively rare adipocytic neoplasm that is easily mistaken for a liposarcoma, and is histologically characterized by a mixture of uniform spindle cells and mature fat cells. It occurs predominantly in male patients aged $45\~65$ years, and in most cases it arises in the subcutaneous tissue of the neck or shoulder. We report a case of a 45-year-old woman with spindle cell lipoma arising from the left pleural cavity.

Chondrolipomas, which are lipomas with chondroid metaplasia, are rare benign soft tissue tumors with no relevant epidemiological reports or radiological information. A limited number of lipomas with osteo/chondroid differentiation have been reported in the literature between 1960 and 2008. Moreover, only few studies have described the radiologic findings of chondrolipomas. Herein, we present a case of chrondrolipoma arising from the left supraclavicular region in a 77-year-old female.
