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 report a case of rhinocerebral mucormycosis in a 63-year-old female with a 1-year history of poorly controlled diabetes mellitus. She had black necrotic ulcers on the hard palate, bloody nasal discharge, swelling of the left side of her face, left blepharoptosis, proptosis, and conjunctival injection. Histopathological examination of the palatal lesion showed large, nonseptate, right-angled branching fungal hyphae in the dermis, and Rhizopus species was isolated on Sabouraud's agar media. The patient was treated with a combination of amphotericin B and surgical debridements but died of asphyxia one month after admission. This is a relatively uncommon, opportunistic infection occurring in a diabetic woman, and only several cases are reported in the Korean literature up to date.

Granuloma pyogenicum is a benign vascular tumor and usually occurs as a single lesion. But in a few instances, the development of multiple satellite lesions has been observed following excision or irritation of the primary lesion. Multiple satellite granuloma pyogenicum is a very rare variant of granuloma pyogenicum and occurs most commonly on the back, chest, or trunk, particularly in the interscapular region during childhood. We report a case of multiple granuloma pyogenicum which occurred on the unusual site of the scalp in a 70-year-old woman. The patient presented with a reddish pedunculated nodule with multiple satellite lesions on the right temporal area. The histopathologic findings of the primary and satellite lesions showed many newly formed capillaries and characteristic epidermal collarettes. The lesions were treated by surgical excision and electrodesiccation.

A 51-year-old female had disseminated, symmetrically distributed, brownish black pigmentation and papillary hypertrophy on the intertriginous and flexural areas for 6 months, and gastric adenocarcinoma was confirmed during the evaluation of internal malignancy, The cutaneous finding of acanthosis nigricans was a significant cutaneous marker of internal malignancy in this case.

We experienced a case of generalized granuloma annular e in a 68-year-old man. Many factors have been implicated in the genesis of this disease, but in this case no etiologic factors were identified. He was treated successfully with systemic corticosteroid for about l year.

Great difficulty may be encountered in the differentiation of basal cell carcinoma from trichoepithelioma snd, in some cases, it may even be irnpossible. Immunohistochemical methods using peanut agglutinin(PNA) which is glycoprotein of non-immune origin selectively binding to galactose-N-acetyl-galactosa-mine are increasingly used in dermatopathology to improve the diagnosis and differential diagnosis. Using PNA, anti-PNA antibody, and peroxidase antiperoxi-dase(PAP) technique, normal skin specimens, basal cell carcinomas, trichoepitheliiomas, and a variety of different skin tumors were studied, and different PNA Ibinding sites between basal cell carcinomas and trichoepitheliomas were observed. The results were as follows : l. In normal skin, except the basement membrane, epidermis and hair follicle epithelium showed a cell membrane staining of PNA, which stained weakly in the Ibssal cell layer. Sebaceous glands revealed membranous and cytoplasmic staining of PNA, but sweat ducts and duct coi1s were mostly negative. 2. 34 of 36(94.4%) basal cell carcinoma sections demonstrated peritumorous PNA-positive bands, and none of 5 trichoepithelioma sections showed peritumorous PNA-binding. 3. Peritumorous PNA-positive bands were strongly positive in solid and keratotic basal cell carcinomas, but decreased or absent in the vicinity of the ulceration or the dense inflammatory infiltration. 4. None of the other skin tumors(squamous cell carcinoms, keratoscanthoma, Bowens disesse and actinic keratosis} showed a periturnorous PNA-positive band. Therefore, we believe that the PNA staining on paraffin-embedded sections using PAP technique can be a useful probe for the differentiation of basal cell carcinoma from trichoepithelioma.

We report a case of Mycobacterium(M.) fortuitum infection in a 65-year-old female who presented with erythematous to purplish colored tender nodules and plaques with curst and purulent discharge on both upper and lower extremities along the sites of acupuncture. The culture of surgically excised specimen in 3% Ogawa media yielded slightly yellowish colored colonies within 2 days. Several tests for identification of the species were performed and growth on 5% NaCl, negative niacin test, positive results in nitrate reduction, catalase, urease and iron uptake tests were noted. Excision of the lesions followed by administration of minocycline and ciprofloxacin showed no sign of relapse to data a year after treatment.
