We report a case of acral persistent papular mucinosis in a 5 year-old female with multiple papules on both dorsa of the hands, wrists and forearms. Examination of a biopsy specimen showed a domeshaped lesion in the dermis composed of spindle-shaped fibrobla,sts and widely spaced collagen fibers. These spaces were filled with mucinous material, as demonstrated by positive staining with aleian blue at pH 2.5 and pH 0.5.

Exogenoue exposurea to pathogenic fungi have been suggested as causes of acute atta.eks of tinea pedis. Psthogenic fungi is rarely present on the skin aurfaces without cauaing definite and characteristic reactions. However, it was suspected by eome observers that pathogenic fungi might be more or liesa normal inhabitant of the human skin. Alterations in host susceptibility and loss, of local immunity are more to blame than new exposure to exogenous micro-ganisms. To determine this point, fungal culture was done from the fourth toe web of 824 high school students. The results of the study were summarized as follows,' l. Among 824 cases, 780 cases(94.7%) had grossly normal appearing toe web and 44 cases(5,3%) were suspected superficial fungal infection. 2. Positive rate of KOH examination was 4.6%(36,'780) in normal toe web and 45.4%(20/44) in dermatophytic lesion. 3, The positive rate of fungal culture from normal and infected toe web are 7.9 %(62/780) a.nd 40.9%(18/44), respectively. In the normal toe web, Trichophyton rubrum(66.1%), T, entagrophytea(include T. interdigitaLe) and Epidermophyton, floccosum(3.2%) were isolated. In the dermatophytic lesion, T. rubrurn(88.8%) and T. me ntagrophytes(11.2% ) w ere isolated. Although toe webs do not present clinical symptoms and signs, pathogenic fungi as a normal inhabitant can be isolated from clinically normal toe webs. Some of these cases, therefore, will develope to tinea pedis in time.

A 26-year-old man presented with a bluish speckled patch on the dorsum of the left hand. It had apperaed at birth as a bluish spot. Since adolescence the lesion extended and at the time of visiting hospital it covered the most part of the dorsum of the left hand and even some palmar aspect. The histopathological and ultrastructural examination revealed numerous dermal melanocytes, mainly in the upper dermis. Clinically and pathologically, the patient was diagnosed as having dermal melanocyte hamartoma, a distinct type of dermal melanocytosis.

Among the patients visting Department of Dermatology, Chungman National University, 58 cases had various side effects due to the malpractice of skin disorders. We analysed these 58 cases and the results can be summerized as follows ; 1. 37 cases(64%) were in the second and third decades and 11 cases(19%) were under 19 years-old. 2. Drug medication from pharmacy was the most common(79%), and then local clinics(12%), herb clinics(9%) in decreasing orders. 3. In the route of administration, oral ingestion(38%) was the most common, and 47 cases (81%) were medicated with adrenocorticoids. 4. In motivation to the visit, 31 cases(53%)were by advice, 15 cases by advertizement and 12 cases (21%) by themselves. 5. Acne and psoriasis were about a half of pre-existing skin diseases. 6. Side effects due to malpractice may be divided into 5 items : systemic side effects due to adrenocorticoids (59%), aggravation of pre-existing skin diseases (22%), topical side effects due to adrenocorticoids (10%), chemical irritation and burn (7%), and mercury intoxication (2%) in decreasing orders.

Since adult human skin can be grown in chernically defined medium without serum, the skin organ culture has gained a great interest as a method for studies concerning skin biology, pharmacology and toxicology. however, serum supplementation has extensively been used to improve the viahility of tissue culture. This study was undertaken to evaluate the effect of serum on the histologic changes ohserved during the organ culture of the normal human skin. The general architecture of the skin was well maintained for 6 days with or without seru. After then, fetal calf serum or autologous human serum was found to enhance the viability of the epidermis. A confluent layer of necrotic spinous ceils was ovserved earlier and more widespread without serum. The addition of serum had an impressive effect on epibolization. In the absenee of serum, the formation of the epibolus was not only minimal, but also, susceptible to degeneration, and no epibolus remained at 10 days rif incubation. No difference can be found between fetal calf serm and autologous human serum in the formation of the epibolus. There was no favorable effect of serum on the formation of new stratum corneum. The thickness of new straturn corneum increased in parallel with the number of parakeratatic cells, increasing most rapidly between 6 and 8 days of incubation. Parakeratosis was more prominent in the presence of serurn.

Bullae and sweat gland necrosis have been often described in patients with mental ges, whieh commonly alanifested as erythematous or vesicobullaus lesions on pressure sites. Histopathologically, the aecrosis of sweat glands is a characteristic 6nding. Generalized and/or loca1 tlssue bypoxia due to prolonged ieamobihxation may have resulted in these clinical and histopakological manifestations. To date, we have experielwed 15 cases with bulla and sweat gland necrosis. On admission, about half the patients had carbon monoxide poisoning, and the remainders had alcohol overdosage, drug inioxication, and others. A11 our patients had menfal changes caused by carbon wonoxide poisening, aleohol intoxication, and others. Abrupt erythematous swelling and/or vesicobullous lesione affected pressure sites in all patients. Three patietns had erythematoias lesiqms on non-pressure sites simuhtaneously. Histopathologic examinatians of 12 biopsy specimes showed the necrosis of the epidermis, intra- or sub-epidermal bulla, and/or sweat gland necrosis.

We present three cases of eosinophilic pustular folliculitis without eosinophilia in a 19-year-old female, a 27-year-old male, and a 51-year-old male. Multiple erythematous plaques with papules and pustules were observed on the face in two patients and on the face, trunk, and extremities in the third patient. Histopathologic findings showed hair follicles and the sebaceous glands infiltrated with mixed inflammatory cells composed of eosinophils and neutrophils, characteristic of eosinophilic pustular follicultitis. However, peripheral blood eosinophilia was not present in any of our three cases.

Benign symmetric lipomat,osis is a rare disease of undetermined cause characterized by symmetric deposits of adipose tissue o:n the neck, upper trunk and abdomen. We report three cases of kienign symmetric lipomatosis, one of which is associated with alcoholic liver disease and the patient complained of a diffieulties in neck motion, All of them are about sixty year old men with history of frequent alcohol consumption. In histopathologic findings, the reticular dermis was completcly replaced by mature fat cells and there was a slight increase in vascular and fibrous elements.

We report a case of a skin problem induced by a visual display t rminal in a 24-year-old female. The patient had erythematcn.is rashes, crusts on both zygomatic areas and upper eyelids with itching, burning and pain sensations after she had been exposed to her visual display terminal. After the cassation of exposure, her skin lesions were markedly improved. A proioction test with her own visual display terminal was positive.
