A Case of Type V Hyperlipoproteinemia with Xanthoma Eruptivum / 대한피부과학회지

We report a case of type V hyperlipoproteinemia with xanthoma eruptivum in a 30-year-old male. He had diffuse erythematous yellowish papules on both extremities and the buttock. The laboratory findings showed the increased cholesterol and the triglyceride. Serum electrophoresis showed an increase in pre-beta and chylomicron, suggesting type V hyperlipoproteinemia. The biopsy specimen of an erythematous yellowish colored papule on the right knee showed many aggregates of foam cells without Touton giant cells.

A Case of Scleredema Preceded by Upper Respiratory Infection / 감염

Scleredema is a rare connective tissue disease of unknown etiology and characterized by non-pitting thickening of subcutaneous tissue of the neck, face, head, upper trunk and arms. We present a 28 year-old man with extensive skin changes following upper respiratory infection, who have not any concurrent disorders such as diabetes mellitus. Histopathological findings of skin showed normal epidermis with a widening of spaces between collagen bundles by infiltration of acid mucopolysaccharide in the dermis.

A Case of the Secondary Localized Cutaneous Amyloidosis due to Atopic Dermatitis / 대한피부과학회지

Secondary localized amyloidosis of the skin is occasionaly associated with keratoma, epithelioma, seborrheic keratosis, chronic dermatitis, etc. It was generally known that amyloidosis, especially lichen amyloidosis, is frequently seen in atopic disorders. But the exact mechanism and relationship of atopic disorders to the development of the amyloidosis is obscure still nowadays. This 72 years old male patient was suffered from itching sensation on the whole body which is suggested to be atopic dermatitis since about 35 years ago and pruritic lichenoicl papulonodular eruptions developed on the extensor surface of the lower extremity first since about 10 years ago and then occured gradually on the thigh and extensor surface of the arm and forearm in both side. The charateristic lesions seems to be lichen amyloidosis. But we suggest thc case is secondary localized amyloidosis of the skin probably due to atopic dermatitis in according to past history, physical examination and eosinophilia without other definitive diseases, The therapeutic results were not promissing, however itching and lichenoid papules were much disappeared during the treatment with steroid cream for occlusivc dressing therapy and oral use of steroid.

A Case of Mucoepidermoid Carcinoma of Parotid Gland Origin / 대한피부과학회지

Mucoepidermoid earcinoma occurred in about 2% among salivary gland tumor and in about 15% among malignant parotid gland tumor. The tumor occurred usually in elderly persons and arose as innocent-appearing swelling in the parotid gland region with gradual painless enlargement without alarming and it's usual size is less than 2 cm, However, a few of the poorly differentiated neoplasms grew rapidly and were painful and accompanied by facial nerve paralysis in about 15%. But it's prognosis is better than other salivary gland origin. We report a case of typical mucoepidermoid carcinoma of parotid gland origin which is occurred in 15 years old girl. The tumor begins pea sized painless nodule since about 2 years ago, and enlarged gradually to apple size and accompanied by facial nerve paralysis and pain sensation recently. But there was no evidence of tumor in parotid gland itself and no metastasis.

Effect of the Various Drugs on the Permeability of the Isolated Frog Skin / 대한피부과학회지

One of the most interesting subjects in the field of dermatology has become the clarifying of the action mechanism of various drugs in promoting skin permeability in regard to their usefulness or harmfulness to various skin diseases. Although dimethyl sulfoxide (DMSO) detergents and propylene glycol were well known as having a promoting effect on the skin permeability, but the exact action mechanism of them was still unknown because of difficulty in methodology. So an attempt to clarify the action mechanism and find out the differences in the mode of action between them have been made by using frog skin, which has been used in research for the 'membrane transport', during past but having complex structures i.e. soley as 'skin' in this study was done. Abdominal skin was removed from frogs, Rana nigromaculata, captured on the area of Kyung Ki Do. In a series of experimental procedures about effect of experimental agents, short circuit current (SCC) as an estimate of net flux of sodium transport and potential difference (PD) was measured by the method of Ussing and Zerahn(1951). And changes of SCC and PD was observed during treatment with bathing mediums which contained agents and maintained iso-osmorality by varying amount of sodium chloride. These were compared including the effect of concentration of each experimental agent. The experimental agents used were DMSO and various detergent, i.e., sodium lauryl sulphate(SLS): anionic detergent, benzalkonium chloride (BAC): cationic detergents, and 'Tween-80: nonionic detergents. Results obtained are summarized on the followings. 1. The promoting effect of the sodium lauryl sulphate on the active sodium transport was reached to maximum within 10 to 20 min and was present until 40 min. after bathing with it, and thereafter, sodium transport was inhibited irreversibly at the both sides of the frog skin. And the maximal promoting effect of the SLS induced by increasing concentration had relationship in such a way on the saturation curve. 2. The active sodium transport was always increased on the inside of the frog skin after bathing with benzalkonium chloride (BAC) and in spite of changing of bathing medium with Ringer's solution, the active sodium transport was steadiIy increased even beyond the effect of BAC except temporally decreasing just after the bathing with Riger's solution. But the frog skin died within 20 min. at the outside after bathing with BAC. 3. Tween-80 brought about reversible reaction increasing the active sodium transport across the frog skin at the inside after bathing. And it seemed to be parallel to the degree of tle coneentration of it. 4. The effect of dimethyl sulfoxide (DMSO) on the active sodium transport across the frog skin was altered seasonaly, i.e., promoting sodium transport during the summer months hut inhibiting it during the winter months. So it was suggested that the action of DMSO on the sodium transport depends on the metabolic rates of the frog skin and the action differed from that of ADH hormone which promotes the sodium transports only in winter months. Also the effect of the DMSO differed from various detergents in view of seasonal variation and reversibility of the action of it. From the above resu]ts, this experimental method should be used more preferably using isolated frog skin in the research for clarifying the action mechanisms of the various other drugs in skin permeability.

Disseminated Superficial Actinic Porokeratosis (DSAP): Report of Two Cases / 대한피부과학회지

Disseminated superficial actinic porokeratosis (DSAP) is one of the recently found skin disorderes, which was differentiated from classicaI porokeratosis (Mibelli) and senile keratosis etc. in view of clinical features and hietogenesis by Marvin E. Chernosky on 1967. The one was 60 years old female patient, who had been suffered from multiple dark-brownish keratotic uniform minute papules on dorsa of the hands, forearms and neck with accompanying itching sensation since about 20 year's old of her age. The another one was 38years old housewffe, wha had been suffered from same lesions of the former on the face, neck, extremities especially sun-light exposed area. In both cases, skin lesions were exacerbated during each summer season and increase in numbers of the skin lesions with more severe itching sensation. Chernosky postulated none of a dark-sklnned race affording natural protection against sun-light had skin lesion of D S A P, we were abIe to find out two cases of typical D S A P ih the Korea.
