A case of peripheral neuroblastoma of a 33-year-old male, which was located on the left buttock, is presented. Histologcally, this tumor demonstrated smaliound cell infiltrations which were arranged in a characteristic rosette pattern and the tumor cells were positively stained with neuron specific enolase. We review the clinical, histopathological ultrastructural and immunohisto chemical characteristics of this rare tumor, as well as the differential diagnosis with other small round cell tumors.

Plexiform neurofibroma is considered a pathognomic of Von Recklinghousen's disease, which involves the deep and large nerve trunk. These are large irregular nerve fascicles which result from an increase in endoneural matrix within individual nerve facicles, without an increased number of nerve fibers. We experenced a case of Von Recklinghausen's disease in a 24 year-old male who had variable cutaneous skeletal, and CNS lesions. He presented multiple neurofibromas, cafe-au-lait spots, and axillary freckles as common cutaneous lesions of NF-I and giant pigmentation, sacral hypertrichosis, and plexiform neurofibroma as unusual cutaneous lesions. Also he had a scoliosis, bowing deformity of the humerous and wedging deformity of the body of the 5th cervical spine as a skeletal manifestation and cortical calcification in the occipital area as a CNS manifestation.

We present herein a case of pyoderma gangrenosum, which showed good response to cyclosporine therapy. The patient, a 47-year-old man, had suffered from a skin defect on the left anterior chest 2 months before the rapidly spreading pustules and ulcer with an inflammed, irregular undermined border appeared together with a hemorrhagic base which developed on his left anterior chest and upper abdomen. Cyclosporine was given orally in a dose of 150mg three times daily for 2 weeks, and tapering to 100mg three times daily for the next 3 weeks. Clinical improvement was observed after 14 day's treatment and all the skin lesions were replaced by granulation tissue with epithelialization after 35 day's treatment. After the 5-week period of treatment, blood urea nitrogen and creatinine rose to 29 and 1.8 mg/dl. Cyclosporine was stopped and then the patient was given prednisolone (10mg/day) in addition to dapsone(50mg/day) for 1 month. Recurrence has not been observed.

A case of multiple trichilemmal cysts (TC) is presented. TC is known to be a kind of keratinous cyst with lining cells showing trichilemmal keratiniration. A 63-year-old female patient presented with a 30 year duration of increasing in size and number of twenty five nodular lesions on the scalp. All twenty five TC on the scalp were totally excised and examined microscopically. However, the evidence of proliferation or malignant change like the previous case reports was not found in our case.

BACKGROUND: Although the histologic picture of epidermolytic hyperkeratosis is diagnostic for bullous congenital ichthyosiform erythrokerma (BCIE), it is not specific for it. It is found also in several other conditions, that is, linear epidermal nevus, epidermolytic keratisis palmaris et plantaris and epidermolytic acnthoma. Among these, BCIE is caused by mutations of the defferentiation s0pecific keratins K1 and K1-. These mutations produce a weakened cytoskeleton that is prone to collapse resulting I cell fragility and lysis. But the pathogenesis of epidermal nevus showing the similar histologic feature with BCIE is not known. OBJECTIVE: The purpose of our study is to conpare the electron microscopic picture and the immunohistochemical features, and to find the possible pathogenesis of both diseases. METHODS: We evaluated the clinical, histopathologic nd electron microscopic features of 5 BCIE cases and 14 epidermal nevus cases which were histologically diagnosed with epidermolytic hyperkeratosis at the department of dermatology at Wonju Christian Hospital, Shinchon Severance Hospital and Yongdong Severance Hospital, from January 1981 to June 1994. The immunohistochemical staining(PAP method) using monoclonal antibody against cytokeratin was performed on BCIE and epidermal nevus. RESULTS: Light microscopy of both BCIE and epidermal nevus showed the same histologic changes including hyperkeratosis, increased keratohyaline granules, acanthosis and perinuclear vacuolization of upper malpighia layer. Electron mioroscopic findings in both diseases were similar. Aggregation of tonofilaments is noted in the squamous cells, but is not evident in basal cells.In immunohistochemical study of both diseases, 34betaE12 is stained in the whole epidermis and is stuonger ex0ressed in the basal layer tan suprabasal layers. LP34 staining is evident in suprabasal cell layers up to the cornified cell layer. CONCLUSION: Electron microscopy and immunohistochemical study of both diseases showed the same finding. We thind that a defect in the differentiation specific keratins, K1 and K10 is perhaps involved in epidermal nevus histologically showing epidermolytic hyperkeratosis as in BCIE.

A 55-year-old Korean female patient who presented with longitudinal black pigmentation affecting the right thumbnail is described. Direct microscopic examination of nail tissue in 15% potassium hydroxide and cultures on Sabourauds glucose agar revealed Candida species. Cardida species as a cause of longitudinal melanonychia has, to our knowledge, been described only once in the literature. Our case may be the second one.

BACKGROUND: Xerosis is a relatively common disorder, especially in the elderly. The condition is characterized by fine scaling and is associated with generalized pruritus. OBJECTIVE: The purpose of this study was to evaluate the clinical efficacy, safety and tolerability of Zalsming cream in patients with xerosis and pruritus. METHODS: Thirty patients were treated with Zalsming cream. Clinical efficacy, as measured by the score of subjective symptom and objective signs, transepidermal water loss(TEWL) and electron microscopic finding, were asessed at 2, 4, and 6 weeks after topical application of the cream. RESULTS: The scores of clinical signs and TEWL showed statistically significant improvements. No one developed any local or systemic side effects. CONCLUSION: Topical application of Zalsming cream was found to be effective and safe for patients suffering from xerosis and pruritus.

We report a interesting case of acral lentigenous malignant melanoma associated with pseudocarcinomatous hyperplasia in a 65-year-old women A skin lesion showed a 5 x 5cm sized, black colored protruding mass with ulcerative surface on the right great toe for the last 10 years. Histopathological findings reveled hyperplasia of epidermis and the epithelium of the upper protion of the adnexa admixed with a proliferation of atypical epitheloid melanocytes that involved the mid and lower portion of the epidermis and the papillary dermis. There were dyskeratotic cells and pseudohorn cysts between the aggregates of atypical melanocytes. Immunhistochemical staining revealed that the nucleus and cytoplasm of the atypical epitheloid cells were strongly positive for S-100 protein and negative for keratin. Keratin staining revealed aggregates of positively stained kertinocytes with dyskeratosis and pseudohorn cysts admixed and trapped among negatively stained atypical melnocytes. A unusual case of malignant melanorna associated with pseudocarcinomatous hyperplasia in which conventional hematoxylin and eosin stained sections were difficult to differentiation between malignat melanoma and squamous cell carcinoma. Immunohistochemical staining for S-100 protein and keratin were essential in establesging the correct diagnosis.
