BACKGROUND: The incidence of Cutaneous malignant tumors has increased recently and they have varied in their developing patterns according to social and environmental influences. However, we have little clinical data about the cutaneous malignant tumors in the Chonnam provinee. OBJECTIVE: Our purpose was to analyze the clinical characteristics of cutaneous malignant tumors observed in the Chonnam province and to compare them with the data previously reported in Korea. METHOD: We clinically analyzed 427 cases of cutaneous malignant tumors during a 10 year period betwecn January 1987 and Oetober 1996, at the Department of Dermatology, Chonnam Univemity Hospital in Kwangju. RESULTS: 1. The average armual incidence of cutaneous malignant tumors among the total number of outpatients was 1.00+/- 0.25%. The incidence tended to increase with time from 0.90+/-0.29% in the first 5 year-period to 1.15+/-0.09% in the late 5 year-period. The increasing rate was most pronmient in basal cell carcinoma. 2. The most common tumor in the 427 patients with malignant tumor was basal cell carcinoma (52.5%), followed by squamous cell carcinoma (19.9%), malignant melanoma (13.3%), metastatic carcinoma (3.7%), malignant lymphoma (2.3%). 3. The mean age of onset was 60.7+/-16.0 years old (male; 59.6+/-15.0, female; 61.9+/-17.1) in the in the group as a whole; 63.9 in BCC, 63.3 in SCC and 55.8 in malignant melanoma. The ratio of men to women was 1.14:l. 4. The most common site of a11 malignant tumors was the head and neck (64.6%), where 89.3% of BCC, 58.8% of SCC, and 15.8% of malignant melanoma developed. The next common site was the lower exlremities and feet (15.7%) followed by the trunk (7,7%), and upper extremities and hands (7.3%).

Nevus sebaceus of Jadassohn has been referred to as a organoid nevus that classically evolves through three stages and may be associated with a range of skin tumors, and of these, syringocystadenoma papilliferum and basal cell carcinoma have been commonly reported to occur. The occurrence of keratoacanthoma is a very rare event in nevus sebaceus. Herein we report on a 23-year-old man with nevus sebaceus of the cheek. He represents a keratoacanthoma arising within nevus sebaceus.

We report two cases of cellulitis on the saphenous venectomy scar which developed after a coronary artery bypass graft(CABG). A 68-year-old male and a 62-year-old female developed acute cellulitis in the saphenous vein donor extremity after CABG. The repeated bacterial cultures were negative in both cases. However, onychomycosis was confirmed in one patient. The intervals between CABG and the initial bout of cellulitis in the male and female patient were 10 and 22 months, respectively. Although the exact pathogenesis remains obscure, factors such as direct bacterial infection, hypersensitivity to streptococcal exotoxins, a local compromise of lymphatic and venous drainage, and fungal infection might have contributed to the development of cellulitis in these patients.

PURPOSE: Transglutaminase 4 (TGase 4) belongs to a family of enzymes that catalyzes the post-translational modification of proteins. In an attempt to establish its physiological function(s), the distribution of TGase 4 expression in the human eye was determined. METHODS: Ocular tissues obtained from five human whole eyeball postmortem (40(+1) weeks at gestation age, 2 months, 48, 66, 76 years) were stained with monoclonal antibodies against human TGase 4 using indirect immunohistochemical method. RESULTS: TGase 4 was found in the lacrimal glands, corneal epithelium and endothelium, conjunctival epithelium, lens epithelium, retina (inner segment of photoreceptor, external limiting membrane, outer plexiform layer, inner plexiform layer, retinal nerve fiber layer and internal limiting membrane), iris, ciliary muscle, ciliary nonpigmented epithelium and trabecular meshwork. Endothelium of blood vessels in all ocular tissues was also stained. Conjunctival stroma, choroid, anterior tenon's capsule were faintly stained. No evidence of immunostaining for TGase 4 was found in the corneal stroma, iris stroma, lens nucleus, ciliary process, sclera, extraocular muscle and optic nerve. CONCLUSIONS: The expression pattern of TGase 4 was different from those of other TGase isoforms in the human eye. This result may be helpful in further investigation of the role of TGase 4 in the ocular tissue.

Herpes zoster is an uncommon disease in children, especially in healthy children. The clinical studies and observations of herpes zoster has been focused to children with hemato-oncologic diseases or immuno-compromised conditions. Recently the association of herpes zoster after varicella vaccine (Oka strain) immunization has been concerned and some cases of normal children after varicella vaccination have been reported. We experienced two cases of herpes zoster in healthy children after varicella vaccination.

BACKGROUND: Rosacea is a chronic skin disease which primarily affects the face. There have been many basic and clinical studies on rosacea in the West, but little in Korea. OBJECTIVE: This study was to investigate clinical features of rosacea in Korea and to compare them with those in the West. METHODS: During a 20-month period, 67 patients diagnosed as having rosacea were examined for their clinical presentations by means of personal interview. RESULTS: Erythema and telangiectasia were found in almost all of the 67 patients. Comparing with the results in the West, flushing and telangiectasia were more common whereas papules, pustules, and rhinophyma were less common with no case of ocular complaints or migraine. CONCLUSION: Because early detection and treatment is necessary to prevent the progression of rosacea, it is important to realize that rosacea is not uncommon in Korea and to recognize its somewhat different clinical manifestations from those in the West.

It is well known that hypertension is associated with left ventricular diastolic dysfunction which frequently precede systolic dysfunction. To determine whether nifedipine could improve left ventricular diastolic function in hypertensive patients, we studied 15 hypertensive patients and 15 normotensive subjects matched for sex, age with Doppler echocardiography. After oral administration of 10mg of nifedipine, there were no significant changes in Doppler-derived transmitral diastolic filling indexes of normotensive subjects. On the other hand, although peak flow velocity in atrial systole(PFVA), time velocity integral in atrial systole(TVIA) did not change significantly after nifedipine, nifedipine significantly increased peak flow velocity in early diastole(PFVE) from 40.2+/-6.4cm/sec to 46.5+/-10.9cm/sec(p<0.005), time velocity integral in early diastole(TVIE) from 5.24+/-1.2cm to 5.97+/-1.43cm(p<0.001), the ratio of PFVE/PFVA from 0.69+/-0.11 to 0.76+/-0.12(p<0.05), the ratio of TVIE/TVIA from 1.18+/-0.21 to 1.29+/-0.24(p<0.05), deceleration slope(DS) from 244.9+/-51.9cm/sec2 to 289.9+/-49.1cm/sec2 (p<0.001) and decreased isovolumic relaxation time(IVRT) from 132.3+/-10.3msec to 117.2+/-13.5msec(p<0.001), deceleration time(DT) from 168.8+/-30.3msec to 154.9+/-29.8msec(p<0.05) in hypertensive patients. These fimdings indicated that nifedipine improves Doppler-derived early diastolic filling indexes in hypertensive patients and may be related to improvement of active relaxation of left ventricle in early diastole.

BACKGROUND: Conventional vertical sections of scalp biopsy specimens are often inadequate for the diagnosis of alopecia. Alternatively, a better approach can often be provided with the use of transverse sections continues, which is readily available and continues to grow in popularity. OBJECTIVE: The purpose of this study was to compare the histopathologic findings of transverse and vertical sections of scalp biopsy specimens in various types of alopecia. METHODS:A total of 27 scalp biopsy specimens obtained during the past 16 months for the evaluation of alopecia was processed for either transverse or vertical section, or for both. With these sections a quantitative morphologic study was done by counting a variety of follicular structures, and any specific histopathologic changes were recorded. RESULTS: Diagnostic features that were better seen in vertical sections included quantitative morphologic changes of a variety of follicular structures such as total number of follicles, catagen and telogen hairs, vellus hairs and follicular stele, as were anagen-telogen ratios and terminal-vellus ratios. Other histopathologic findings that were better demonstrated in transverse sections included peribulbar inflammatory infiltrate for alopecia areata, miniaturization for androgenetic alopecia, trichomalacia and pigment cast for trichotillomania, and fat atrophy for pressure alopecia. In some cases, especially for scarring alopecia, vertical sections also allowed for useful adjunctive diagnostic information such as follicular destruction, dermal fibrosis and sclerosis, and interface change. CONCLUSION: Transverse sections of scalp biopsy specimens provided many useful information in histopathologic diagnosis of alopecia. But, in some cases of scarring alopecia, vertical sections provided more diagnostic findings. To overcome the diagnostic limitation of transverse sections, therefore, observing both transverse and vertical sections at a time could be an alternative way of enhancing diagnostic yield of alopecia.
