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.

PURPOSE: To investigate prognostic factors influencing on local recurrence, distant metastasis and event-free survival of liposarcomas. MATERIALS AND METHODS: Fifty-two patients managed for liposarcomas since 1993 were analyzed respectively in the view of prognostic influence of patient age, tumor size, location, histologic type, histologic grade, resection type, surgical margin, chemotherapy and radiation therapy on local recurrence, distant metastasis and event-free survival. The mean follow up period was 39 months. The univariate and multivariate regression analysis were performed for statistical evaluation. RESULTS: The local recurrences occurred in 11 patients (21.2%) and distant metastasis in 4 patients (8%), Event-free survival rate at 4 year follow up was 67%. In univariate analysis, histologic grade, surgical margin, chemotherapy and radiation therapy were significant prognostic factors on local recurrence (p<0.05). However, histologic grade lost its significance in muitivariate analysis. Trunk location revealed higher rate of distant metastasis than extremity location. In univariate analysis on event-free survival. histologic grade and chemotherapy were significant factors (p<0.05). No factor remained significant in multivariate analysis. CONCLUSION: Considering selection bias, positive surgical margin was negative prognostic factor on local recurrence. Liposarcomas arisen in trunk revealed higher rate of distant metastasis. There was no independent prognostic factor on event-free survival of patients with liposarcomas.

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.

This study was designed to investigate the effects of occlusive dressing with corticosteroid on the count, size and morphology of corneocytes of normal human skin. We select 16 male volunteers, aged 23 to 25 years, without skin lesions. They were divided to 2 groups according to duration of occlusive dressing, 3 days to group 1 and 6 days to group II. Specimens were obtained from 4 sites on the back, which were studied for the effect of occlusive dressings without any topicals, with 0.l% hydrocortisone-l7-butyrate cream, with 0.25% desoxymethasone ointment, and with base of desoxymethasone, before and every 3 to 5 days after occlusive dressings, up to a total 4 times in group I and 5 times in group II.

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.

Juvenile spring eruption(JSE) of the ears is an unusual type of photodermatosis, which develops on the light exposed areas of the ears of boys and young male adults in the early spring months. JSE has received little attention in the literature, and to our knowledge no cases have been reported in Korea until now. Herein we report a case of JSE occurring in a 17-year-old man who has suffered from a recurrent pruritic erythematous papulovesicular eruption of both helix, followed by crusting and healing without scarring within one to two months early each spring for six years.

Digital subtraction angiography(DSA) was made in 72 patients at department of radiology, Seoul National University hospital from February 1982 to January 1983 with our system, SRM-II, developed by cooperation of department of medical engineering, Seoul National University Hospital. The results were as follows; 1. In the total 72 cases, vascular disease was 28 cases in which aortic disease including Takayasu's aortitis was 18 cases. Others were vascular tumors in 32 cases and various conditions such as renal donor and artificial arteriovenous shunt. 2. Extent of the lesion was well delineated especially in aortic disease in cluding 8 cases of Takayasu's aortitis, 6 cases of aortic aneurysm and 2 cases of Behcet's syndrome. 3. DSA can be done to outpatient without admission because of its simplicity and non-invasiveness. DSA is useful especially in the evaluation and follow-up of vascular disease and the diagnostic value is expected to grow continuously according to the renewal of system.
