The fifty gastrointestinal polyps, which were removed endoscopically frorn 47 patients at the Seoul National Univeraity. Hospital from January, 1978 to September, 1983, were reviewed with regard to the clinical and pathological features. The observed data are as follows; 1) Fifty polyps were reoved from 10 patients with gastric polyps and 37 patients with colonic polyps. Out of 37 patients 26 were male and 21 female, the sex ratio being 1.2: 1. 2) The gastric polyps were located in the body and antrum and 90 per cent of the colonic polyps were found in the left colon, especially in the rectosigmoid colon. 3) Out of the 10 gastric ployps snared, 8 could be retrivevd, 2 being lost. The histological examination showed that 3 were hyperplastic polyps, 2 gastritis verrucosa, 1 inflammatory polyp and the remaining 1 revealed intramucosel carcinoma with borderline epithelium. 4) Fourty polypectomies were performed in 37 patients with colonic polyps. Histological examination revealed that 24(60%) were adenomatous polyps, 9(22.5%) retention polyp, 4 (10.0%) inflammatory polyp and 3(7. 5%) Peutz-Jegher's poIyps. Among the adenomatous polys, 4 cases were complicated with focal adenocarcinoma. 5) Except the 2 cases of post-polypectomy bleeding, no other complication was encountered. The one case of hemorrhage after gastric polypectomy was treated with transfusion of 2 pints of whole blood, and the other case after colonic polypectomy required exploratory laparotomy because of inability of bleeding control by electrocoagulation.

This sutdy was designed to localize the distribution of basic fibroblast growth factor(bFGF) in the developing rat condylar region and to elucidate the associated function of bFGF in the condyle development. The condyles of temporomandibular joint of Sprague-Dawley rats (27g of weight) were used. The tissues were examined with electron microscope and immunohistochemical method. The results were as follows: 1. The developing condylar region are divided in to 5 zones apparently: proliferative, maturation, hypertrophic, calcifying, and ossification zones. 2. The cells in the proliferative zone are condensed and have under-developed cell organells in the cytoplasm. This zone shows a strong immunoreactivity of bFGF. 3. The cells in the maturation zone are typical chondroblasts showing well-developed cell organells and round nucleus. The cartilaginous matrix does not show the immunoreactivity of bFGF, while the chondroblasts show the immunoreactivity. 4. The cells in the hypertrophic zone show hypertrophic change having the degenerated cell organelles and small nucleus. There are no immunoreactivity of bFGF in this zone except the nucleus and endoplasmic region showing mild immunoreactivity. 5, The cells in the calcifying zone show hypertrophic change and cell organelles are disappeared. The cells are surrounded by the calcified cartilaginous matrix. There are no immunoreactivity of bFGF in this zone except the endoplasmic region showing mild immunoreactivity. 6. In the zone of bone formation, chondroblasts are disappeared. Newly differentiated osteoblasts secreting osteoid around the calcified cartilaginous matrix. The bone marrow shows the immunoreactivity of bFGF, while the bone matrix does not show the immunoreactivity of bFGF.

Two cases of clear cell syringoma are reported in the women who were 39 ad 54 years old, respectively. They had had asymptomatic, ricegrain-sized skin colored to yellowish pink papules on the face, particularly on he lower eyelid for several years. Interestingly, both of them had suffered from diabetes mellitus for more than a decade and been placed on irregular antidiabetic medications. Routine laboratory findings in the elder patient(case 2), unfortunately not checked in the younger patient(cases 1) due to her refusal, were within normal limits except marked glucosuria. Histologic examination revealed numerous various-sized, well-defined tumor nests composed largely of clear cells with polygonal cellular boundary and eccentric nucleus. Special stain with Periodic acid-Schiff disclosed existance of glycogen in the clear cells, but other special stains such as alcian blue showed negative findings. Electron microscopic examination of the elder patient revealed many multivesicular bodies suggestive of lysosomes, and numerous droplets of glycogen dispersed between them in villi-rich periluminal cell.

The leukemias are a heterogeneous group of neoplasms arising from the malignant transformation of hematopoietic cells. The cutaneous lesions associated with leukemia may be divided into the specific (leukemic infiltration) and nonspecific (leukemids). These may occur separately or in combination with each other. A 28 year old man admitted to the Department of Dermatology in December 1989, for diffuse infiltrated skin lesions of five months duration. In July 1989, he had experienced hyperpigmented diffuse infiltration on the face, which gradually spread to involve the neck and trunk. In November 1989, he felt cervical, submandibular, and inguinal lymph node enlargement. Skin biopsy specimen showed diffuse dermal and subcutaneous infiltration of atypical lymphocytes. Bone marrow biopsy and peripheral blood smear specimen showed changes of acute lymphoblastic leukemia(L). In addition, we studied infiltrated cell.; by immunoperoxidase staining with a pannel of monoclonal antibodies. The results revealed that the atypical cells expressed mainly helper/inducer T cell marker.

We report a case of sebaceous carcinoma arising from nevus sebaceus of Jadassohn ocurring in a 68-year-old male, who showed a pedunculated cauliflower like tumor mass on verrucoid linear plaque in the fronto-parietal scalp. Histopathologic findings revealed mult,iple irregular tumor lobules composed mainly of foamy cytoplasmic atypical cells suggesting undifferrntiated sebaceous cells. Good result was obtained with wide local excision and primary closure without recurrence for 9 months after surgiral excision.

During the three years from March, 1983 to Feb, 1986, 159 cases of head injury surgically treated in the department of neurosurgery, Capital Armed Forces General Hospital were clinicostatistically analysed and discussed with the review of the literature. The following results were obtained.1) Due to the army distinctiveness, all cases were male and the age incidence was becoming maximal at the third decade. 2) Traffic accidents form by far the largest Group(38.4%), and next are, in order of incidence, accidents due to fall from height, simple fall(19%), exercise(12.6%), gun shot wound or explosive injury(9.4%) and assault(9.4%). 3) Skull fracture were seen in 115 cases(72.3%), and nearly half of those 55 cases, were linear fracture. 4) Of the 133 patients with intracranial hematoma or subdural hygroma, 88 cases(66.7%) were accompanied by skull fracture. 93% of epidural hematomas were associated with skull fracture and the most common wite of hematoma was temporoparietal area. 5) Of all cases of subdural hematoma, acute type was prevalent(59.4%) and its main site involved was temporoparietal area. 6) The associated injuries were found in 22.6% of patients. The frequent ones were facial bone fracture, upper extremity fracture, clavicle fracture, and chest injury, in order. 7) The minor head injury of Glasgow coma scale score(GCS) of 13 to 15 was 68 cases(42.8%). The moderated head injury of 9 to 12 was 28 cases(17.6) and the serve head injury of 3 to 8, 63 cases(39.1%). 8) The operation mortality was 26.8% and the good recovery was achieved 55.4% of patients. The remaining 18.8% resulted in disabled or vegetative state. 9) In the accidents of gun shot wound or explosive injury, operation mortality rate was 60%, but 5 cases(33.3%) were seen good recovery.

As jaws of children differ from those of adults in the aspects of architectural and mechanical properties, site, form and treatment modality of pediatric fractured jaws are somewhat different from those of adults. This study takes stastics of 33 pediatric patients with mandibular fractures (55 fracture sites) who were admitted to the department of oral and maxillofacial surgery. Kyung-hee university from May 1986 to March 1995, aged up to 15years with primary or mixed dentition, by age, cause, site and treatment modality. The results are as follows. 1. The mandibular fracture has sexual predilection for male, 0 to 3 years group. 2. The main cause of mandibular fracture is falling from various position, followed by traffic accident. 3. The highest incidence of fracture site is symphysis and/or condyle area. 4. Circumferential wiring is widely used for pediatric mandibular fracture.
