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.

To delineate the coronary anatomy and the left ventricular function during early myocardial infarction, coronary arteriography and left ventriculography were performed prospectively in 28(34%) of 83 patients who were admitted to the coronary care unit at Severance Hospital from November 1983 to August 1984 within 30 days(median : 14 days;range : 4 hours to 30 days) after the onset of symptoms. The frequency of total occlusion of the infarct related artery was evaluated in the time course of infarction. To prove spontaneous recanalization, 3 patients who had total coronary occlusion underwent serial study within 11-20 days after the first study. We categorized the patients into two comparable groups according to the infarction site, coronary angiographic findings, and age. Comparison of clinical and angiographic findings between each group was made. The following results were obained. 1) There were 23 patients with transmural myocardial infarction(82.1%) and 5 with nontransmural infarction(17.9%). Among 23 patients with transmural infarction, 14 had anterior infarction(60.9%) and 9(39.1%) inferior infarction. 2) The mean age was 51.3 years(range : 31-79 years). The ratio of male to female was 3.7:1. 3) Fifteen patients(53.6%) had one-vessel disease, 10(35.7%) two-vessel disease and 2(7.1%) three-vessel disease, One patient(3.6%) had insignificant disease(less than 50% reduction in luminal diameter). Nontransmural infarction had a tendency to be associated with higher prevalence of multivessel disease than transmural infarction(80% vs 34.8%). 4) In 23 patients with transmural infarction, 12(52.2%) had complete occlusion and 11(47.8%) incomplete occlusion of the infarct related artery. Three patients(13.0%) had subtotal occlusion(90-99%) and 4(17.4%) had lesions of 70-89% luminal diameter narrowing. Three patients(13.0%) had 50-69% lesions and the remaining 1(4.4%) had insignificant obstructive lesions. 5) Of the 23 patients with transmural infarction, 12 were studied within 14 days and 11 in 15-30 days after the onset of symptoms. The frequency of total coronary occlusion was significantly higher in the patients studied within 14 days of symptom onset vs those studied in the 15-30 days period(83.3% vs 18.2%;p<0.001). Serial studies of 3 patients with total coronary occlusion at the initial study demonstrated occurrance of spontaneous recanalization in 2 patients. 6) The left ventricular-ejection fraction was higher in the patients with nontransmural infarction, inferior infarction, and incomplete coronary occlusion(65+/-14%, 58+/-16% and 57+/-17%) than that of the patients with transmural infarction, anterior infarction, and complete coronary occlusion(51+/-15%, 47+/-14% and 46+/-13, p<0.05). But there was no significant difference in left ventricular ejection fraction between the young(<45 year) and the old(> or =45 year) age groups. And also 0-1 vessel disease and 2-3 vessel disease groups did not show significant difference in ejection fraction. The degree of congestive heart failure was more severe in the patients with anterior infarction than in those with inferior infaction. multi-vessel disease group was significantly older than 0-1 vessel disease group(55+/-8 yrs vs 46+/-12 yrs, p<0.05), and the young age group had a tendency to be associated with higher prevalence of single vessel disease. 7) As for the complications of angiocardiography in this study, there was ventricular finbrillation in 2 patients(7.1%) without mortality. It is concluded that coronary arteriography can be safely performed within one month after acute myocardial infarction;high prevalence of one-vessel disease in acute myocardial infarction in the Korean adult patients admitted to a general hospital;lower incidence of total coronary occlusion in the late time course of infarction due to spontaneous recanalization;better left ventricular function in the patient groups with nontransmural infarction, inferior infarction and incomplete coronary occlusion.

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.

Supernunmerary nipple is a developmental anomaly occuring alon, the course of the embryological milk lines. This entity has receieved little attention in the dermatologic literature and has been confused with a pigmented nevus in some cases. We have experienced two ease of the more unusual form of supern umerary nipple. According to the Kajavas classification, our caes are classified as polithelia pilosa and complete breast with nipple.

We report a case of herpes zoster with generalized varicelliform eruption. A 56-year-old male presented with rice-sized erythematous grouped ruptured or crusted vesicles with a band-like distribution on the left chest and back and generalized rice-to-pea-sized erythematous vesicles on his whole body. Histologic examination revealed ballooning degeneration and multi-nucleated giant cells in the epidermis and leukocytoclastic vasculitis in the dermis.

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 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.
