Though basal cell carcinoma is the most frequent and increasing malignant tumor of the skin in Korea, its pathological analysis has been done only on the small numbers. So, we did a comprehensive pathologic study on the 283 patients with basal cell carcinoma diagnosed in the Department of Pathology, Seoul National(233cases) and Chung-Ang(50cases) University Hospital during 1975-1992. The age distribution was ranged from 15 to 84 years with highest incidence rate in the age group of 5th-8th decades and 83.7% of all patients were over 40 years of age. Sex difference was not noted. The most common site was face occuring in 235 out of 283cases(83.0%) especially in the eyelid(25.5%), nose(17.9%) and cheek(16.6%). The most frequent histopathologic type was solid type(54.0%) followed by mixed(23.9%), adenoid(7.5%), and metatypical(4.7%). Among 51 mixed type, all showed solid components with adenoid(51.0%) followed by morphea(25.5%) and metatypical type(13.7%). And among 14 recurrent cases, solid type is found in 50% of cases. The characteristic clinicopathological findings are solid arrangement of tumor cells with various histological pattern and predominant occurence on the face.
Incidence

Malignant tumors of the small bowel are uncommon by comparison with those in other parts of the gastrointestinal tract. Adenocarcinomas account for about half of the malignant tumors of the small intestine, which account for 1% to 2% of the gastrointestinal neoplasma. Small-bowel tumors are often asymptomatic and without clinical significance, and later became symptomatic and are eventually fatal. Patient's with regional enteritis, especially those who have had segments of the intestine surgically by passed, have an increased incidence of small-bowel cancer. The author experienced a case of an adenocarcinoma at the jejunostomy site (Braun anastomosis) which was treated by using a B II type subtotal gastrectomy for stomach cancer. That case of a jejunostomy site adenocarcinoma is reported and the literature on small-bowel malignancy is reviewed.

PURPOSE: The purpose of this study was to evaluate the spectrum of MR characteristics of cystic acoustic neurinomas and to correlate with pathologic findings. MATERIALS AND METHODS: We retrospectively reviewed the MR findings of 12 patients with cystic acoustic neurinomas. The signal intensity and enhancement pattern of the cystic components as well as the location relative to the tumors were analyzed. RESULTS: A total of 30 cysts were found in 15 acoustic neurinomas;28 were intratumoral cysts and the remaining two were extratumoral cysts. The signal intensity of all 28 intratumoral cysts was higher than that of CSF on Tl-weighted images, and isointense to CSF on T2-weighted images, while the signal intensity of the two extratumoral cysts was same as CSF on both Tl-weighted and T2-weighted images. Rim enhancement was seen in 27 of 28 intratumoral cysts but in none of the two extratumoral cysts. CONCLUSION: We concluded that intratumoral cyst was due to tumoral necrosis, hemorrhage or degenerative change and extratumoral cyst due to secondary arachnoid cyst formation.

Spinal epidural abscesses were evaluated using Gadolinium-enhanced magnetic resonance imaging (MRI) in 19 surgically and clinically confirmed cases, including 13 with tuberculous spondylitis and 6 with pyogenic spondylitis. We observed rim enhancement patterns in 10 patients and diffuse enhancement patterns in 9 patients. The spread patterns were localized to ventral or dorsal epidural space and encircled entire epidural space. We conclude that rim enhancement indicates abscess and diffuse enhancement indicates granulation tissue and fibrosis. Tuberculous epidural abscess spreads to ventral epidural space and pyogenic epidural abscess encircles entire epidural space.

BACKGROUND: Allergic diseases are characterized by immediate - and late - phase reactions to various allergens by the selective activation of a subset of CD4 + T cells. In response to allergen, T cells isolated from atopic donors are biased to low levels of IFN - y and high levels of IL - 4, and vice versa by T cells from non - atopic donor. Objective : The aim of this study was to evaluate the patterns of IL - 4 and IFN - y production after Der p I stimulation and the effect on the cytokine production from T cells by budesonide, disodium cromoglycate and cyclosporin A in atopic and non - atopic individuals. MATERIAL AND METHOD: Seven Der p I specific atopic and 7 non - atopic individuals were selected. We decided the 50% inhibiting concentration of each immunomodulator by lymphocyte proliferation assay, and measured their effects on the cytokine production in vitro by intracellular IL - 4, IFN - y staining and flow cytometry. Results and CONCLUSION: There was significant difference on stimulation index ( SI ) of production of IFN - y as well as IL-4 after Der p I stimulation between atopic and non-atopic individuals ( IL - 4 ; 1.57 +/- 0.7 : 0.98 +/- 0.2, p = 0.026, IFN - r : 1.45 +/- 0.5 : 0.95 +/- 0.2, p = 0.048 ). The synthesis of IL - 4, and IFN - r were significantly inhibited after the stimulation of every immunomodulators in atopic individuals, DSCG couldnt inhibit IL - 4 and IFN - r in nonatopic individuals. There was no significant difference in the inhibiting effect of these immunomodulators in both of them.
