Benign tumors and tumor like lesions in the foot are uncommon and those that are malignant are rare. Metastatic cancer of bone distal to the knee and elbow is unusual. By contrast, non-tumorous lisions that cause swelling, pretuberance, or deformity are common. Fifty two cases of tumors on foot were treated at our department from Jan. 1970 to Dec. 1991, we have treated fifty two cases of foot tumor and analysed their clinical characteristics. Bone tumors were more frequent than soft tissue tumors (2:1). Among soft tissue tumors benign tumors were frequent than malignant(1.4:1), and fibroma was the most frequent tumor(30%). Benign soft tissue tumors occured frequently at Edward and Michael's Zone 3(57%). Benign bone tumors has higher incidence than malignant(20:1). Osteochondroma was the most frequent tumor (48%). Predilection sites for osteochondroma and enchondroma of foot was distal phalanges and mitatarsal bone, respectively.

Juvenile spring eruption(JSE) of the ears is an unusual type of photodermatosis, which develops on the light exposed areas of the ears of boys and young male adults in the early spring months. JSE has received little attention in the literature, and to our knowledge no cases have been reported in Korea until now. Herein we report a case of JSE occurring in a 17-year-old man who has suffered from a recurrent pruritic erythematous papulovesicular eruption of both helix, followed by crusting and healing without scarring within one to two months early each spring for six years.

A simple and convenient management system in coding and storage of the pathologic diagnoses was developed by generating the dBASE III with IBM-PC microcomputer. The program named "Pathology Slide Bank" can store about 3,600 data according to the SNOP coding in a standard 51/4 inch floppy disk and retrieve the data within two minutes.

The simultaneous ipsilateral fractures of the arm and forearm are relatively rare and there is no exact method of treatment for these fractures. Authors has clinically analized 37 cases of these fractures which are treated between September, 1973 and May, 1987 at the Department of Orthopedic Surgery, Hanyang University College of Medicine. The results can be summarized as follows. l. Among 440 patients with humeral fracture, there were associated fractures of the ipsilateral forearm bone in 69 patients (13. 4%). 2. The main cause of these fracture was traffic accident and the next one was fell from a height. 3. The most frequently associated injury was nerve paralysis. 4. The methods of treatment were classified as follows . 1 st method Both arm and forearm were treated by internal fixation (32.1%). 2nd method The arm was treated by internal fixation and the forearm by conservative method (11.8%). 3rd method The arm was treated by conservative method and the forearm by in- ternal fixation (11.8%). 4rdmethod Both arm and forearm were treated by conservative method (44. 3%). 5. By Andersons criteria, excellent and satisfactory results were obtained in 47. 1% of cases which were treated by mainly 1 st method.

Percutaneous chemical neurolysis of sacral nerve with phenol was performed on 11 cases of hyperreflexic bladder to augment bladder capacity and to make intermittent clean catheterization more feasible. Urodynamic evaluations were done before and after chemical neurolysis. Followup ranged from 10 months to 16 months(mean 13 months). Mean bladder capacity increased significantly after chemical neurolysis ( from 157.5ml to 340ml). No significant changes in bowel or injection sites were noted. Continence was improved in 100%, with 7 patients remaining completely dry and voiding with intermittent self-catheterization. The long term results were necessary but we considered the chemolysis of sacral nerve was available modality for hyperreflexic bladder patients, who did not respond to anticholinergic medication, before decide the more aggressive alternatives, such as augmentation cystoplasty or urinary diversion.

Presentation of antigen in a suitable form to lymphocytes is prerequsite for the initiation of primary immune response. Dendritic cells (DC) provide an effective pathway for presenting antigens to lymphocytes in situ. The aim of this study was to establish a dendritic cell-line from human tonsils and to investigate the changes in surface phenotype during culture. Immunohistochemical studies using various surface markers indicated that cultured DC were follicular dendritic cells (FDC) from human tonsils. Cultured DC showed typical dendritic morphology at early stage of culture. Their shape changed into fibroblast-like cells over culture time. Surface phenotype study suggested that cultured DC were distinct from human fibroblast. Antigenic pattern of FDC was changed during culture; I-ILA-DR antigens decreased and HJ2 antigens increased with aging of culture. Functional characteristics of human tosillar FDC will be investigated in the future.

In hypertensive patients it is very important to detect renal artery stenosis or pheochromocytoma, since both diseases are curable causes of hypertension. However, renal artery stenosis can be induced by pheochromocytoma, when the diagnosis of the two simultaneous disease is very difficult. We experienced two cases of pheochromocytoma presented as renal artery stenosis. Pheochromcytoma was overlooked when renovascular hypertension was diagnosed. Pheochromocytoma was found during surgery in one patient and after angioplasty in the other. In both cases, BP returned to normal after surgical removal of pheochromocytoma without repair of the stenosis. Prevention of ineffective and unnecessary renal artery angioplasty of surgery requires knowledge of this unusal association between pheochromocytoma and renal artery stenosis and a high degree of clinical alertness for pheochromocytoma.
