The present study is concerned with angiographic findings of bone tumors in patients who have been admitted to Severance Hospital from April 1968 to March 1971. Angiography of peripheral tumors is a valuabIe procedure in that it provides important information concerning the presence or absence of a tumor, defines its size and extent, and gives indication of malignancy. Angiography as an additional aid in the diagnosis of malignant bone lesions was first presented by dos Santos, Lamas and Caldos (1931). Begg (1955) stated that a normal angiogram of a limb shows that the branches of the main artery follow a slightly curved and undulating course, and that their calibre slowly and progressively decreases. None of these vessels are seen to reach the periosteum, nor is the nutrient artery ever visible. dos Santos (1931) proposed certain angiographic criteria of malignancy, notably the presence of numerous irregular vessels at the transit of the contrast medium from the arteries to the veins. Margulis(1964)stated a large number of malignant neoplasms are highly vascular and present chaotic patterns. Their vessels have irregular lumina and arteriovenous communications are present within them. Areas of intense contrast staining occupy parts of or the entire tumor. This appearance, frequently described, has been assumed to be characteristic of and uniformly encountered in malignant tumors. Angiographies in the present study include 6 cases of Osteogenic sarcoma, 4 cases of Chondrosarcoma, 2 cases of Giant cell tumor, 1 case of Liposarcoma, 1 case of Kaposis sarcoma, 1 case of Hemangioma, 1 case of Metastatic bone tumor, 1 case of Fibrous dysplasia and 1 case of Neurofibromatosis. Angiography was performed 13 times under local and 5 times under the general anesthesis. 20 to 30cc of 50 per cent Hypaque was utilized for examination. Angiographic findings are as follows: 1. HypervascuIarity is seen in osteogenic sarcoma, giant cell tumor, hemangioma and metastatic bone tumor. But neurofibromatosis and fibrous dysplasia are avascular. 2. Irregularity of the vascular net work seems characteristic in osteogenic sarcoma, hemangioma, and metastatic bone tumor. 3. Blood pools are seen prominently in osteogenic sarcoma, giant cell tumor, hemangioma and metastatic bone tumor. but no blood pools in neurofibromatosis and fibrous dysplasia. 4. Arteriovenous shunt is seen in osteogenic sarcoma, chondrosarcoma, hemangioma and metastatic bone tumor. But there is no A-V shunt in giant cell tumor, liposarcoma, Kaposis sarcoma, neurofibromatosis and fibrous dysplasia. 5. Retention of contrast medium is seen prominently in osteogenic sarcoma and hemangioma. But no retention of contrast medium is noted in liposarcoma, neurofibromatosis and fibrous dysplasia. While I do not regard arteriography as a necessary procedure for the differantial diagnosis of all presumptive bone neoplasms, it is indeed valuable in selected cases, in differential diagnosis of bone tumors and in the demonstration of the vascularity and extent of extraosseous soft tissue masses and it can be helpful in selecting an appropriate biopsy site. By indicating the size ar,d vascularity of a lesion and its major blood supply, it may influence the surgical approach.

We analysed 26 cases of pyogenic osteomyelitis of the spine who were treaed at Younsei University Hospital during 25 years from January 1952 to August 1977 by operative or conaervative treatment. The diagnosis of pyogenic osteomyelitis of the spine is not easy and very confused. The cause and entry of the offending organism is mainly by venous drainage from the genitourinary and lower extremity circulation and the next is direct spreading from the adjacent focus. The typical clinical symptom is severe pain and tenderness over the lesion accompanied by febril history and the clinical course is relatively rapid than tuberculosis of the spine. In blood examination leukocytosis is uncommon but it showed relative increase of neutrophils in 62%, and erythrocyte sedimentation rate in 89%. Radiological findings are narrowing of joint space, erosion and/or destuctive change of vertebral body, vertebral marginal sclerotic change, and new bone formation and less frequently abscess shadow. The results obtained from this study were as follows, 1) The incidence of pyogenic osteomyelitis of the spine among total cases of the pyogenic osteomyelitis was 2.5% and the ratio of the pyogenic osteomyelitis of the spine to the spine tuberculosis was 2.8%. 2) The sexual incidence was in 11 and 15 each male and female. and the avrage, prevalent age was 34 years of age. 3) The pathogenic organism was isolated in 20 cases from the diseased focus during surgical procedure; stapyhloccus in 16 cases, pseudomonas in two and in a case of E.coli and proteus each. 4) The lumber vertebrae was mostly involved, i.e.lumbar in 11 cases, cervical in four, thoracic in nine, lumbosacral and sacrum in one each. 5) The operative treatment was performed in 23 cases and conservative in 3 cases with the satisfatory result in all cases. 6) We conclude that the focal curettage with anterior interbody fusion through anterior approach was better than the conservative treatment.

Osteitis condensans ilii is one of the rare disease which represents an alteration in the normal bony architecture of that portion of the ilium alongside the sacro-iliac joint: namely condensation without involvement of joint space or adjacent sacrum. We analyzed clinically 9 cases of osteitis condensans ilii who were treated at the Department of Orthopedic Surgery, Medial college of Yonsei University. The results were as follows :l. All patients were women and oldest patient was 47, the youngest 23 years of age. 2. The pain occured following delivery in 3 cases and in one case ofter trauma. There was urinary tract infection in one case. 3. All patients complained low back pain and the pain extended to buttock in 2 cases whereas the radiating pain to lower extremity in 4 cases. 4. In 4 cases was a positive straight leg raising test elicited. 5. In 3 cases the blood sedimentation rate was increased above normal. 6. All patient succeed in relieving pain with conssrvative treatment. In 2 instances steroid was used. 7. There were combined diseases in 4 cases : herniated nucleus pulposus in 2 cases, rheumatoid arthritis in 1 case, osteoarthritis in 1 case.

Bone formation by osteoblast may be closely related to the increase in intracellular Ca2+ activity of osteoblast. In order to study the effects of changes in Ca2+ activity of osteoblast-like cell on fracture healing, we changed intracellular Ca2+ activity of osteoblast-like cells by vanadate and verapamil. And the process of fracture healing was observed after injection of the treatment osteoblast-like cells into the fracture site by hematoxylin-eosin (H-E) stain and bromodeoxyuridine (BrdU) stain. The results were as follow: 1) The most effective range of concentration which could facilitate bone formation was 10-6 to 10-5 M. 2) H-E stain showed more abundant osteoblast and osteoid tissues, more active mitotic division of osteoblast, and earlier appearance of chondroblast and chondroid tissue, making the maturation of woven bone faster in the vanadate-treated group than in the control group. The opposite was true in the verapamil-treated group compared with the control group. 3) BrdU labeling index showed more active osteoblastic proliferation in the vanadate-treated than in the control group. The opposite was observed in the verapamil-treated group compared with the control group. From these results, the fracture healing appears to be facilitated and decelerated by vanadate which apparently increase intracellular Ca2+ activity of osteoblast and verapamil which decreases it, repectively. Therefore the change of intracellular Ca2+ activity of osteoblast can be considered to be one of fracture healing mechanisms and expected to be applied for clinical purpose.

Many methods of correcting secondary cleft lip nose deformity have been introduced, but a single best method that can be uniformly adjusted for all cases does not exist. Since it is difficult to make the nostril of the cleft side symmetric with that of normal side, the authors tried to formulate the basis for correction of unilateral secondary cleft lip nose deformity according to the varying amounts of deformed nostril. We then adopted 4 different methods of correcting the soft tissue and nostril deformity in 63 patients from 1996 to 1998 and surveyed the results. Our principles were as follows: 1) Alar rim incision was done in cases of different-shaped cleft-side nostrils with nearly the same measured area in comparison to the normal side. 2) When deformity of the alar-columellar web was severe, we performed modified Z-plasty. 3) When the nostril of the cleft-side nostril was smaller than the normal side with slight asymmetry, reverse W-plasty was done. 4) We adopted a reverse-U incision when there was a discrepancy in height with moderate asymmetry compared with the normal nostril. After dissection, repositioning of alar cartilage was done by same method in each case. A nasal stent was kept in position for at least 6 months postoperatively in almost all cases. After follow-up of 6 to 24 months, we concluded that our choice was correct in selecting the optimal operative method, considering the characteristics of deformity of the cleft side nostril in an effort to make it symmetric with that of the normal side.

BACKGROUND: Epidermal cysts are a common occurrence. But there have been few studies to determine the clinical and histopathological characteristics of epidermal cysts. OBJECTIVE: To evaluate the clinicopathological characteristics of 324 cases of epidermal cyst. METHODS: We evaluated the clinical and histopathologic features of 324 cases of epidermal cyst at the Department of Dermatology at Korea University Anam Hospital over 5 years, from January 2001 to December 2005. RESULTS: The ratio of male to female patients was 1.7 : 1. Age distribution ranged from 7 to 91 years old. The duration of lesions was variable with mean duration of 29.3 months. The most common site of occurrence was the face. Histopathologic changes of cystic walls were atropy, acanthosis, hypergranulosis, vacuolation and parakeratosis. We identified parakeratotic cells, red blood cells, calcifications and bacterial colonies in the cystic contents. We also found verrucous architectures in the cystic walls of 23 cases. Initially, some cases were clinically diagnosed as epidermal cysts, but histopathological findings then discovered only inflammation, granulation, pilomatrichoma or lipoma, rather than an epidermal cyst. We discovered that there was also a close relation between erythema and rupture of the cystic wall. CONCLUSION: Our clinical and histopathologic findings of the epidermal cysts were similar to previous reports. However, we did find verrucous architectures on not only the palmoplantar area, but also many other areas of the body. Quite a few cases which had initially been clinically diagnosed as epidermal cysts, turned out not to be upon histopathologic investigation.
