The authors aimed to apply a nonsurgioal and atraumatic method for avulsing dystrophic nails due to onyohomyoosis by using 22.25% urea ointment under occlusive dressing. One hundred and eighty-nine nails with onychomycosis in fifty-five patients were treated by this rnethod. The results obtained a,re as follows: 1. Of a total of 82 fingernails and 107 toenails in 55 patients, all fingernails and 103 toenails showed an excellent response with easy removal of the diseased nails. 2. The duration tha.t the occluded urea ointment remained in place before sucessful avulsion was 6.7(range, 3 to 18) days for fingernails, and 9.1(range, 3 to 18) days for toenails with onychomycosis. 3. Of 4 nails of control group which were treated with white petrolatum, none showed the significant improvernent. 4. The problems during this treatment were; severe irritation with pain(l case), mild irzitation and/or itching(5 cases), and pin-point bleeding on curettage of nail bed (19 cases). It is suggested the urea treatment has many advantages and seemed to be ideal for patients with digital vascular insufficiency and increased susceptibility to infection.

We present a case of bullous congenital ichthyosiform erythroderma in a two year old female, in whom no hereditary background was found. The skin lesion was characterized clinically by blister formation with generalized erythematous hyperkeratosis which was especially prominent on the flexural surfaces of extremities and intertriginous areas. The histopathologic examination revealed marked hyperkeratosis, cavity changes of the malpighian cells with perinuclear vacuoles and markedly thickened granular layer containing many keratohyaline granules.

Clinical study on 62 patients (26 males and 36 females) with neurofibromatosis seen during past ten years at the Department of Dermatology, Pusan National Universitg Hospital, was made the variable clinical manifestations of the disease and Riccardis ciassification were emphasized. The results were as follows . 1) Family history was noted in 32 cases(51.6%) and exhibited autosomal dominant inheritance pattern. 2) Cutaneous neurofibromas were found in 52 cases(83.8%). 3) Cafe-au-lait spots, measuring greater than 1.5cm in its longest diameter, were found in 60 cases(96.8%) and 44 cases(71.0%) had more than 6 in number. 4) Among associated abnormalities were,' mental retardation(20,9%), skeletal abnormalities(11.2%), seizure, severe headache, etc. 5) According to Riccardis classification, 38 cases could be classified as type I, 28 cases(73.7%); type II, 0 case ; type III, 1 case(2.6%); type IV, 3 cases(7, 9%); type V, 1 case(2.6%); type VI, 4 cases(10.5%); type VII, l case(2.6%); and type VIII, 0 case.

We have studied the effects on wound healing of moist conditions in rabbit, achieved by covering excised wounds with the polyurethane film dressings, and dry conditions, by exposure to air during the period from day 1 to day 21 after injury. We have quantified the rate of dermal repair by means of differenetial cell counts of neutrophils, macrophages, fibroblasts, and endothelial cells. The rate of re-epithelialization was also examined. The resuts were as follows: 1. There was an acceleration of the inflammatory phase of repair in the moist wounds. The late phase of inflammation began more rapidly. On day 3 after injury there were 150% more macrophages (p<0.01) and 70% fewer neutrophils (p<0.01) in moist wounds. It was also observed the presence of significantly more fibroblasts (p<0.01) in the moist wounds than the dry wounds. 2. There was also more rapid increase in the number of proliferative phase cells-fibroblasts (p<0.01) and endothelial cells (p<0.01) in moist wounds. the lower content of neutrophils (p<0.05) and the higher number of fibroblasts (p<0.01) which were observed in moist wounds on day 7 after injury suggested that healing was by then well advanced into the proliferative phase. 3. On day 14 after injury, the decrease in the number of fibroblasts in moist wounds suggested that this group entered the remodeling phase of repainr. The lower total cell count in moist wounds than in dry on day 21 after injruy suggested a more rapid progress through the remodeling phase. 4. The reepithelialization of moist wounds was faster than that of dry wounds. These findings suggested that moist wounds occluded with polyurethane film dressing healed more rapidly and in a more orderly manner than did dry wounds, both epidermal and dermal repair being accelerated.

Merkel cell carcinoma (MCC) is an unusual primary cutaneous tumor, occasionally found con-current with other malignancies. A case of MCC with coexisting squamous cell carcinoma (SCC) was studied histologically, immunohistochemically and ultrastructurally. The MCC and SCC occured at the same site, but each preserved its identity and transition between the two was not identified.

Phakomatosis pigmentovascularis was first described in 1947 as a distinctive association of cutaneous hemangioma and pigmentary nevi by Ota et al. We describe a 7-year-old boy who, since birth, had three kinds of discolored patches over the various parts of the body: blue spots (dermal melanocytic nevi), reticulated reddish patches (nevus flammeus), and hypopigmented macules (nevus anemicus). No systemic disease was found.

We presented a case of Ehlers-Danlos syndrome(ED syndrome) in s 21-year- old male, who had hyperextensibility of skin, skin fragility, and cigarette paperlike atrophic scars with no joint problems since infancy. There was a family history which was suggestive of autosomal dominant trait. Microscopic examination of the skin biopsy specimen from the normal appearing skin on the right forearm showed no abnormal appearance. In this case the manifestations of skin including marked hyperextensibility might be in accord with type I (gravis) ED syndrome, but the joint manifestation did not correspond to this type. It might be hard to classify this case according to the eleven types of ED syndrome. Wed rather consider this case as a. mixed form of type I and type Il ED syndrome.

Silver sulfadiazine, an antibacterial agent, has been used successfully in the praphylaxis and treatment of burn infection. 42 volunteers with herpes zoster were enrolled in a clinical trial to evaluate the effectiveness of topical silver sulfadiazine cream. 1% silver sulfadiazine cream was applied 4 times daily until crust removal and epithelialization on 21 patients. As the control, wet compress with 1: 5,000-1: 10,000 KMnO4 solution was done 4 times daily on 21 patients. ln treated group with silver sulfadiazine cream, the durations needed for marked reduction of erythema and edema of lesions, striking control of pain and burning sensation, complete drying of vesicles and crust formation, and crust removal and epithelialization were significantly decreased as compared to the control group. The rate of postherpetic neuralgia was also decreased markedly. The sooner the treatment began after the onset of symptoms, the more dramatic the response was. Signs of local or systemic side effects were not observed.

Letterer-Siwe disease is one of Langerhans cell histiocytosis, with Hand-Schuller-Christian disease and eosinophilic granuloma, characterized by proliferation of Langevha is cell. The clinical course of Letterer-Siwe disease is acute fulmunant of casionally fatal, involving skin and many other internal organs, such as the lymph node, liver, spleen, ung and bone. We present 3 cases of Letterer-Siwe disease with characteristic cutaneous findings and revealed Langerhans granules by imrriunohistochemical stain and electronmicrc scopic examination. All patients died in spite of combined chernotherapy.
