Nevocellular nevi are benign tumors composed of nevus cells, which are peculiar to man and almost everyone has a few nevi somewhere on his body. The dermatologist has a unique opportunity to study the most common neoplaam of man, the nevocellular nevus, becasue of its ready accessibility to visual observation and its simplicity obtaining for microscopic specimen. Much has been leamed last two decades about the nature, origin, and development of the nevocellular nevus. However, most of the these knowledge obtained by investigation of Caucasians. The investigation of colored subjects are scarcely reported. This paper is an attempt to clarify 1) the clinical features of nevocellular nevi developed on Korean, colored race. 2) the incidence of pigmented nevi developed on normal individuals and vitiligo patients. During the last l0 month(1975. 3. - 1975. 12. ) 525 normal individuals and 67 vitiligo patients were randomly selected and were investigated about incidence and clinical morphology(according to Levers clinical classification) of pigmented nevi developed on different body areas. The results were summarized as follows. 1) There was average 20 nevocellular nevi in each Korean individuals. Average 23 nevi was found in male and 15 nevi in female. 2) The number of nevus and its morphology were closely related to the age of host and body areas. 3) The flat type nevi was the most common type nevi and face was the most common site among the body areas. 4) In comparison with Caucasian, it seemed no racial difference in clinical features of the pigmented nevus. 5) There was no difference between the incidence of nevocellular nevus developed on normal individual and that of vitiligo patient.

The mongrel dogs, anesthetized with pentobarbital sodium, were used as experimental animals. The effects of a single intravenous injection of ethyl adrianol. 0.5 mg per kg of body weight, on cardiovascular response and urinary flow were compared with those of epinephrine, 0.05 mg per kg of body weight and norepinephrine, 0.05 mg per kg of body weight. 1) The pressor effect induced with 0.5 mg of ethyl adrianol per kg of body weight was similar to that with equipressor doses, 0.05 mg, kg of epinephrine or norepinephrine. 2) The duration of the pressor action of ethyladrianol lasted at least one hour but only about 15minutes with equipressor dose of epinephrine or norepinephrine. 3) Ethyladrienol was responsible for the increase of the urinary volume, which phenomenon is assumed to be related of the renal-function and the durability of the reaction. 4) Ethyladrianol is considered to be one of the ideal drugs for the treatment of hypotensive shock.

Mixed tumor can be defined as arising from the skin, often from sweat glands, and as being composed of epithelial elements intermingled with cartilage or myxoid tissue in such a way that epithelial cells appear to be continuous with these otber types of cells without separation by a basement membrane. RecentIy, we had opportunity to observe a patient, 34-year-old woman, who had typical mixed tumor of the skin in the central portion of the chin. The tumor developed as a solitary, firm, rice-sized subcutaneous nodule which had been present for 6 months with little increase in size and without any pain and tendemess. The covering skin was normal except mild erythema. Clinically, the lesion was simiIar to sebaceaus cyst, Under local anesthesia, tbe whole tumor mass was removed surgically for histologic study. The histopathologic finding reveals nests of cuboidal or polygonal cells, tubuloalveolar and ductal structures, and homogeneous, faintly bluish chondroid or foamy appearing matrix.

We cairried out this study to find the possibility of itch control with acupuncture under the hypothesis that antipruritic effect also exists if the itch sensation is closely allied to pain. We evaluated the effect of acupuncture on histarnine induced itch, flare and wheal in 20 healthy male volunteers aged 24 32 years old and compared it with the effect of pseudoacupuncture on them and that of no intervention on them. The results were as follows: 1. Mans of itch intensity and duration were decreased in A(session with acupuncture) and P(session with Pseudoacupuncture), compared to those of N(session with no intervention), and A was more effective in decreasing the itch intensity and its duration than P. 2. Means of maximal sizes of flare and wheal were smaller in A and P, but there was no remarkable difference between A and P.

Nevus lipomatosus cutaneous superficialis is a very rare skin disease, which usually is present at birth. The lesion shows groups of asymptomatic soft papules or nodules, which have a smooth or folded surface and are skin colored or yellowish. The area of predilection is the pelvic girdle (especially the buttock and sacrococcygeal areas). Microscopically, nevus lipomatosus cutaneous superficialis reveals groups of etopic fat cell nests within the dermis. Only one case was reported in Korea(1969). The authors observed a case of typical nevus lipomatosus cutaneous superficialis. The patient was 19 year-old male, who ha,ve had asymptomatic soft papules and nodules on the buttock, lower back and scalp since 14 years of his age. Routine laboratory findings were within normal limit. Histopathological findings showed etopic fat cell nests within mid and lower dermis (Fig. 3) Diagnosis was confirmed by clinical and histopathological findings. Litercature was briefly reviewed for the discussion.

We describe herein a 3 family members with phytophotodermatitis. After fig (juice) was applied to skin for the purpose of treating psoriasis in a 30 year-old woman and applied incidentally in her mother and 3 year-old daughter, vesicobullous eruptions developed immediately after sun-exposure, predominantly in the sun-exposed area. ln histopathology, the epidermis shows intraepidermal separation with necrosis and reepithelization on basal layer and marked spongiosis. We treated with systemic steroid, wet dressing with burow solution etc, so she healed without sequela after 2 weeks.

Authors experienced a 13-day-old boy who had suffered from walnut sized hard erythematous nodules on left axilla, anterior and posterior aspect of the neck which began to develop 9 days after birth. Histopathologic findings revealed subcutaneous fat necrosis and needle-shaped cleft in several fat cells. The skin lesions spontaneously resolved at 2 months of age. The clinical pattern, the skin manifestations, and the histologic appearance of the lesions were diagnostic of subcutaneous fat necrosis of newborn.

A case of primary ureteral tumor combined with giant hydronephrosis (3,500ml) was presented with a review of the literature. This case was confirmed with the retrograde pyeloureterogram and biopsy.

Epidermolysis bullosa dystrophica(EBD) is a rare, hereditary and chronic mechanobullous disease characterized by blistering and erosions of the skin in response to even minor trauma. A 5-year old girl visited with a complaint of continuous vesicobullous skin eruptions since birth. On examination, bullae, vesicles, atrophic scars, crusts and ero:ions were scattered on whole body. Loss of finger and toe nails, partial syndactyly of all toe webs and milia on dorsa of feet were noticed. We present a case of EBD that seems to be a recessive type considering the absence of family history with histopathologic and electron microscopic findings.
