There are three major type of malignant melanoma which differ in their mode of onset, course; lentigo maligna melanoma, superficial spreading malignant melanoma and nodular malignant melanoma. Malignant melanoma may aris on apparently normal skin, in a junction nevus, rarely in a compound nevus and extremely rately in an intradermal nevus. We presented a case of malignant melanoma arising from compoud nevus in 51 year old male patient. Ulcerated verrucous walnut sized brown-black tumor mass was nticed on the posterolateral surface of right foot. There were no palpable lymph nodes in whole body. Tumor cells were epithelioid type and lie in irregularly alveolar formation histologically. There were also numerous nevus cells in dermis and nevus cell nest in lower epidermis with tumor cells. Surgical excision of tumor mass and skin graft was performed.

During 1964 to 1967, a survey of 30,534 persons for filariasis was made on all over the country with the following results: Among 24,816 draftees from all over the country in the army recruitment camp 155(0.63 %) were found infected with Brugia malayi. Cheju Do showed the highest microfilaria rate(3.5 %), North Kyongsang Do(1.4 %) the next and South Cholla Do(1.2 %) the third. Blood films from 2,308 inhabitants were examined and 407(17.6 %) showed microfilaria in Cheju Do. 30(3.1 %) out of 974 inhabitants in North Kyongsang Do were found to be infected. The microfilaria rates were 2.0 per cent for 400 inhabitants of Chindo island in South Cholla Do. However, no positive case of microfilaria was found in the inhabitants of Kokumdo among 1,820 persons examined in South Cholla Do and of Namhae island(among 165 persons examined) in South Kyongsang Do. The mean microfilarial density per 20 cu. mm of blood was 52.6 in the inhabitants of Cheju Do, 12.2 in North Kyongsang Do and 27.3 in Chindo island(South Cholla Do). Any distinct relationship between the incidence of positive cases of microfilariae and age or sex of the cases was not observed in Cheju Do. However, in Norh Kyongsang Do and South Cholla Do the microfilaria rate of the male group is higher than the one of the female group of the inhabitants. From the above survey results it turned out that filariasis was found throughout Southern Korea except Kyonggi Do and South Kyongsang Do. A total 30,534 persons examined, 601(2.0 %) were found to be infected by Brugia malayi. Therefore, it seems that there are some endemic foci of malayian filariasis in three main areas such as North Kyongsang Do, South Cholla Do and Cheju Do.

We observed three patients who showed widespread macular ashy-colored eruptions. They fit clinically and histopathologically with the typical erythema dyschromicum perstans (ashy dermatosis). Erythoma dyschromicum perstans is a peculiar pigmented condition of unknown etiology characterized by persistent ashy-gray colored macule, refractory to any modality. All of them have similar skin lesions which are multiple, variable sized oval-shaped, ash-colored macular eruption on the trunk and extremities. Histologic findings of 2 patients reveal the characteristic feature of focal hydropic degeneration of the basal cell layer of the epidermis, perivascular infiltrates of lymphocytes and histiocytes and melanin-laden macrophages in the corium, however, merely pigmentary incontinence into the corium in 1 patient. Literatures are briefly reviewed.

The authors report a case in which a cerebral arteriovenous malformation(AVM'S) disappeared completely and spontaneously within 7 years without bleeding episodes or surgical intervention. During the interval, he has been completely asymptomatic and had received no treatment except anticonvulsant medication for 6 months. There was no more epilepsy and mild muscular atrophy in the right lower extremity. A similar case has previously been described and is discussed briefly along with other cases of complete AVM'S regression.

Trauma is the important cause of death in children and adults. From May 1, 1984 to June 30, 1995, 370 patients were admitted to our hospital for genitourinary injuries. We made clinical observations and compared children with adults on incidence, cause, diagnosis and treatment of genitourinary traumatic patients. As the result, it was no significant difference between children and adults on incidence, sex ratio, cause, hospital stay, and associated injuries. The kidney was the most common organ to be injured and there was no difference in severity of renal injury between two groups. Operative treatments were more common in adults than children, and external genitalia was most common organ to get operation.

Nevus lipomatosus cutaneus superficialis is a very rare skin disease which appears at birth or within the firat two decades of life. This uncommon condition is due to collections of ectopic fat cells within the upper and mid-dermis. There are two clinical forms. The first form is a lesion of zonal distribution, present from birth or childhood, usually on the buttocks or the lower back. The second form, a dome or sessile, papule, begins in adult life and is less restricted in distribution, and occurs also on the limbs Coalescence of soft, yellowish papules tends to form cerebriform plaques. The authors experienced two cases of typical nevus lipomatosus cutaneus superficialis. The first case was a 23-year male who had asymptomatic, soft, skin colored, and pea sized confluent nodules on the right lower back area since at birth. The second case was a 35-year female who had asymptomatic, multiple, soft, skin colored from rice to walnut sized confluent nodules on the coccygeal area which developed at the age of 27. Diagnosis was confirmed by clinical and histopathological findings.

Epidermolytic hyperkeratosis is a rare disease which is extremely variable in its severity. In some patients it may be so severe and generalized during the neonatal period as to be lifethreatening, in others, it is relatively inconspicuous. A bullous eruption is the characteristic finding of the epidermolytic hyperkeratosis The bullous episodes soon become less frequent and more localized and may eventually cesse, but continue into adult life after the age of 20 years in at least 20% of cases. A case of epidermolytic hyperkeratosis is represented. The patient was a 25-year-old male who had ichthyosiform erythroderma and the frequent episades of bullous eruption. The bullous eruption had been subsided under the treatment with oral penicillin administration. The histopathological features of the bullous lesion on his abdomen revealed the features of epidermolytic hyperkeratosis.

The authers report a case of intracerebral extraventricular cyst of possible neuroectodermal origin, presenting as a right frontotemporoparietal mass lesion which has no communication with the subaracnhnoid space or ventricular system. A 4 months old male patinet recovered rapidly after partial removal of cystic wall, cystoventriculostomy and cystoperitoneal shunt. The pathogenesis and principles of diagnosis and surgical management of this rare lesion is discussed.

The objectives of the study were to provide the basic informations needed in the development of balanced medical services throughout the nation. As the national health care system was expanding rapidly along with the economic growth, quantitative re-evaluation of the system is of great need. For that reason, characteristics of the admitted patients were analyzed for the case-mix and patients' flow within and through regions. Materials were 421,530 cases of inpatients, who were reported through Medical Insurance Corporation(KMIC) for insurance claim, during the period of March 1, 1985 through February 28, 1987. Korean Diagnosis Related Groups(K-DRGs) classification system was adopted for the study of case-mix and 189 cities and countries were classified into 5 district groups by factor analysis results of K-DRGs. The major findings of this study were as follows ; 1) Factor analysis of case-mix, employing K-DRG system, revealed 5 distinct functional district groups. Group A(18 district) was prominent for tertiary medical care. In group B(36 districts), rather simple procedures were prevalent. Group C(26 districts) was distinctive for the medical care of well organized internal medicine practices with qualified clinical laboratories. Group D(17 districts) was characterized by relatively high balanced medical care. Group E (92 districts) was with very low level of medical care. 2) Analysis of the case-flow through the districts showed 3 types of flow patterns ; inflow, outflow, and balanced types. Inflow type of case-flow was found in Group A, C and D while Group B and E showed outflow type. Inflow was most prominent in Group A and Group E was of typical outflow type. Group B was consistently the outflow type except for Major Diagnostic Category XX regardless of the disease treaders, but Group C and D were inflow or outflow types according to the disease tracers.
