Nickel is widely known throughout the world as a common source of contact dermatitis. Korea is one of the rapidly developing countries where the use of nickel and nickel by-products is on the rise. Lacking in ore, Korea imports most of its nickel. In the last ten years, in relation to rapid industrial development, the amount of nickel imported has increased over 1, 000 times. Nickel dermatitis is becoming an increasing problem in the patch test clinic. With regards to this, we have tried the dimethylglyoxime spot test to all materials mentioned in the textbooks which are regarded as nickel sources in other industrialized societies, so as to make an up-to-date list of nickel sources applicable to Korea. In addition, we have also included traditional nickel sources such as acupuncture needles, fire pot, old and new coins and chest of drawers etc. We also have analyzed data concerning nickel imports to Korea during the past 10 years.

The pathogeoesis of papulonecrotic tuberculid had been thought to be the result of hernatogenous dissemination from primary tuberculous focus of other organs. But, today, the existence of papulonecrotic tuberculid as a rare cutaneous reaction to the Mycobacterium bacillus is questioned. Papulonecrotic tuberculid is, however, a real entity in underdeveloped countries where tuberculosis is more common. We report a case having papulonecrotie tuberculid associated with cervical lymph node tuberculosis confirmed by typical histopathology and by clinical response to antituberculous chemotherapy. This case supports Iden et al's view (1) that skepticism regarding the existence of papulonecrotic tuberculid is probably the result of the current decreased prevalence of untreated tuberculosis and consequently increased rarity of this entity.

Malignant angioendothelioma is an uncommon malignant vascular tumor featuring endothelial cell, and it occurs most frequently in sixth and seventh decade. Most lesions occur over the face and scalp, and may be solitary or multiple, The lesion usally appears as a localized dark red to purplish nodules or plapue with small satellite nodules. Histopatholgic finding shows a nodule eomposed of irregular vascular spaces lined by plump endothelial cells stroma. We present a case of malignant angioendo thelioma on a 42 year-old woman. The patient had purplish nodule with satellite lesions on the right cheek. This case was confirmed by clinical picture, histologic findings and electron microscopic examination.

The brief report of Zeisler (1922) of a pregnant woman with scattered telangiectasia in a unilateral distribution is perhaps the first recorded case of this syndrome. The syndrome has been described in association with pregnancy, puberty, alcoholisrn and cirrhosis, hormonal therapy and congenital status. The authors observed in a 17-year-old male unilateral telangiectatic lesions over the left C, C, C, Tl and T, dermatomal regions. The lesions developed at first at his puberty on the anterior part of the chest as speckled bright red discoloration. Thereafter, the lesion has been progressed to involve the left upper extremity, sholder, upper middle part of the chest, eventually. Family history was negative and physical, lahoratory and X-ray examination were all negative or within normal limit. No mucous membrane involvement was observed. On histopathologic examination of the skin lesion, thin walled ectatic vessels lined with single layer of endothelial cells were observed in the upper dermis. The lesions were partly dermabrased with favorable result.

PURPOSE: We evaluated the survival rate, prognostic factors and patterns of failure in malignant and atypical meningiomas, and investigated the role of radiation therapy in the treatment of these tumors. MATERIALS AND METHODS: We retrospectively reviewed nineteen patients treated at Asan Medical Center between Mar. 1994 and Jun. 2000 with histologically confirmed malignant or atypical meningiomas. The median patient age was 52 years. The extent of surgery prior to radiation was gross total resection in 13 and subtotal resection in 6. Eleven patients were referred for radiation immediately after diagnosis and the remainder after at least one recurrence. All patients received megavoltage radiation to a median dose of 55.8 Gy. The median follow-up period was 41 months. RESULTS: Eleven patients (57.9%) showed no evidence of disease, five patients died of meningioma and three were alive with disease. The 5-year overall and relapse-free survivals were 75.9 and 50.6%, respectively. There were no statistically significant prognostic factors found to be associated with relapse-free survival by univariate or multivariate analysis. During the follow-up period, no significant treatment-related complications were detected. CONCLUSION: The major patterns of failure were in-field recurrence. In order to reduce local failure, a higher radiation dose may be needed and a high precision therapy should be considered.
