PURPOSE: To analyze clinical, radiological and pathological features as well as clinical outcome after surgical treatment of patients with secondary chondrosarcoma arising from osteochondroma(tosis). MATERIALS AND METHODS: We retrospectively reviewed clinical records, radiographs, pathologic slides of 14 patients. Nine patients were male and five were female. The mean age was 34 years. The mean follow-up period was 54 months. RESULTS: All patients had a history of previous mass since childhood or puberty. Preexisted osteochondroma was single in 3 patients and multiple in 10. Remaining 1 patient had multiple osteochondromatosis with enchondromatosis. MRI clearly provided thickness of cartilage cap, which was over 2 cm except in 2 cases. Chondrosarcoma was grade 1 in all except 1 case, which was grade 2. Wide excision was performed in 10 patients, marginal excision in 3 and amputation in 1. Twelve patients were doing very well without evidence of disease. Among 3 patients with marginal excision, 1 patient had local recurrence and 1 patient died of disease. CONCLUSION: Comprehensive understanding of clinical, radiological and pathological features of secondary chondrosarcoma is warranted for accurate diagnosis. The best result can be expected with early recognition of malignant change of osteohcondroma(tosis) and wide excision.

Infantile fibrosarcoma is a rare malignant soft tissue tumor occurring especially in newborn and young children under 2 years. We experienced three cases of infantile fibrosarcoma presenting in the neonatal period. Case 1 presented with a multiseptated cystic mass on his left thigh at birth that was diagnosed as lymphangioma. After picibanil injection, we noted the size of the mass doubled and a solid lesion was prominent in the magnetic resonance image. Case 2 was found to have a reddish mass on his lower back mimicking hemangioma. Over 2 weeks, the mass grew rapidly with internal hemorrhaging. Case 3 was noted to have an encircling mass around the splenic flexure, which developed into congenital bowel obstruction. All of the tumors were resected completely, but microscopic resection margin was not clear in two patients. The two patients received adjuvant chemotherapy and all patients are well without evidence of recurrence.

Milia en plaque is characterixed by multiple milia-like lesions within an erythematous edematous plaque in the postauricular area. The histopathological findings are those of milia. We report a case of milia en plaque occurring on the scapha's fossa of the left auricle in a 3-year-old boy.

Moyamoya disease is a rare occlusive cerebrovascular disease characterized by stenosis or occlusion of the main cerebral arteries. It has a tendency for multifactorial inheritance and familial occurrence, although its pathogenesis is not clear. We observed this disease in two girls from the same family:one was eight years old and the other was 45 months. They presented with transient ischemic attacks. We performed cerebral angiography on both patients and magnetic resonance angiography (MRA) on the younger. Both approaches showed the typical features of moyamoya disease, and MRA successfully revealed abnormal findings specific for the disease in the second child. Both children received encephaloduroarteriosynangiosis (EDAS) and this produced good results. MRA is thus a powerful and noninvasive way of detecting individuals at high risk of developing this disease. Considering the reported familial incidence of moyamoya disease in Japan, a careful search for family members using MRA would probably reveal many more such cases in Korea.

We described a case of diffuse biphasic cutaneous amyloidosis, a unique form of localized cutaneous amyloidosis. A 41-year-old man has gradually developed a lichenoid papular and a grouped spotted pigmented macular eruption on the trunk and upper extremities over the past 15 years. Histopathologic examination revealed that amyloid deposits were present in the papillary dermis. It was confirmed by Congo red staining, immunohistochemistry and electron microscopy. There was no evidence of systemic amyloidosis.

The geriatric population tends to increase, worldwidely, and the same in orthopedic fields. In this age group, senile changes, both physical and mental, appear. In addition, psychiatric problems due to retirement from the job and changes of the role in his society and in the family, are included. The geriatric orthopedics is peculiar and its importance is increasing, which makes great demands on both medical and surgical skills as well as an enthusiastic teamwork. Fifty six patients over the age of 70, who were admitted and treated at the Department of Orthopedic Surgery, Seoul National University Hospital, between 1986 to 1987, were analysed. The results were as follows. 1. Thirth four patiens were female and twenty two were male. 2. The fracture was the most common cause, and degenerative arthritis, tumor are the next causes. 3. Operation was performed in 38 cases. 4. The associated diseases were hypertension, diabetes, U.T.I., renal failure, poor sight, pulmonary and cardiovascular diseases, which were more common than other age group. 5. Intra or postoperative complications were hypertension, liver function abnormalities, renal and respiratory failures and et al., which were also more common. 6. Old age is a major risk factor for surgery, but is not a contraindication, so careful evaluation and managements are needed, which can be done by specialized geriatric orthopedic team.

The blood management act was revised on December 4, 2020, to enhance transfusion management and has been established in accordance with the department of transfusion management in the medical institution. The department of transfusion management is involved in education related to transfusion, transfusion monitoring, and ward rounding. The department of transfusion management is essential for promoting the stability and safety of transfusions. This paper aims to help the department of transfusion management operation by sharing the experience of the department of transfusion management.
