Ultrasono-guided percutaneous catheter drainage of 28 abscesses and fluid collections was performed. In 24cases, operation was avoided and the patients were cured(24/28). Of these, 4 cases were recurred and repeatedcatheter drainage was performed. There were two failures and partial success was achieved in 2 cases; in thesepatients, operation was necessary, although the patients benefited from the percutaneous drainage. Cures andpartial successes totaled 26/28. We describe significance of the diagnostic needle aspiration, especially inpredicting the drainability of cavity contents. We review aspects of postprocedurecatheter management includingirrigation and timining of withdrawal.

The ultrasound-guided fine needle aspirations were performed in order to diagnose a suspected neoplastic orinfectious diseases in 52 patients with focal liver disease. Of these, neoplastic lesions were suspected in 31patients and infectious lesions in 21 patients ultrasonically and/or clinically. The overall accuracy for bothsuspected malignant and infectious disease was 79%(41/52). The primary indication for fine needle aspiration wasto document the presense of malignancy and to avoid a diagnostic laparotomy, and to drain hepatic abscesses.Consequently we were convinced that the ultasound

The rhabdomyosarcoma of the prostate is very rarely encountered in the western literature, and only a few reports have been published in Korea. The authours recently experienced two cases of rhabdomyosarcomas of the prostate in 35-year-old and 51-year-old males who had suffered from gross hematuria and difficulty of urination. Microscopic studies showed embryonal type of rhabdomyosarcoma in two cases. The clinical and pathological features of the distinctive prostatic rhabdomyosarcoma are described, and a brief review of the literature is made.

The eccrine poroma was described first by Pinkus et al. in 1956 as a subgroup of benign solid hidradenoma with the histologic structure resembling acrosyringium. The histologic appearance of eccrine poroma greatly resembles that of seborrheic keratosis and basal cell carcinoma. But the clinical lesion is fairly unique and the tumor is most commonly found almost exclusively on the foot, in the skin of the plantar surface. During the past four years, the authors experienced five cases of eccrine poroma which were diagnosed by histopathological examination of the tumor mass. All the cases occurred in the sole and lateral sides of the foot as well. Clinical and pathological features were reviewed and a brief review of the literatures was done.

BACKGROUND: The use of prednisone in the treatment of myasthenia gravis (MG) has been required circumspection because of its tendency to produce exacerbations of weakness in the early stages of treatment, often requiring critical management. However, factors influencing the exacerbation has not been defined well. The purpose of this study was to evaluate the clinical factors predicting the exacerbation by prednisone in the early stage of treatment in MG. METHODS: Fifty five patients, first-ever prescribed high dose prednsone (40-80 mg) during hospitalization in Samsung Medical Center were included. Prednisone induced exacerbation was defined as significant exacerbation of objective neurologic signs of MG within 4 weeks after prednisone addition by utilizing Myasthnia gravis Severity Scale (MSS). We investigate the differences between the exacerbated and nonexacerbated groups in the clinical, laboratory and electrophysiological features. RESULTS: Twenty three patients (42%) experienced definite exacerbation after prednisone treatment. Old age, presence of bulbar symptom, and severe neurologic finding reflected by MSS score were significant predictors of prednisone induced exacerbation in multivariate logistic regression analysis. Higher prednisone dosage per body weight (Kg) was neither a significant predictor of exacerbation nor related with the early improvement in bivariate correlation. CONCLUSIONS: Prednisone induced exacerbation in MG is a frequent challenging problem to clinician. Clinicans should keep in mind the possibility of exacerbation of MG when prescribing prednisone especially, to old, bulbar dominant, severe and disable myasthenic patients.

During the past 1 year the authors experienced 2 cases of fetal cerebellum in an immature teratomaof the ovary which were diagnosed by the histopathological examination of the tumor mass removed by the surgical operation. The first case was a 15-year-old female. At laparatomy an infant head sized mass at the site of the right ovary was removed. The ovary was replaced by a large, predominantly solid and focally cystic mass which weighed 810 gms. and measured 16x14x11 cm. The second case was a 10-year-old female. The right ovary was replaced by a large cystic and focally solid mass which weighed 730 gms. and measured 15x13x10 cm. The cystic portion of the tumor was made up to multiloculated cysts filled with serous fluid. Microscopically, the first case showed an abundant mature tissue from the three germ layers, but this was intermixed with small foci of neuroepithelial tubules present in groups. Well formed fetal cerebellar folia(18 folia) characterized by a definite external granular cell layer, molecular layer, Purkinje neurons and an internal granular cell layer was identified. The second case revealed a predominantly mature tissue. Mature elements from the three germ layers were present. There are small foci of immature neural tissue growing largely in the form of neuroepithelial tubules. Fetal cerebellum with well formed folia(13 folia) was also identified. A brief review of the literature and a discussion on the clinicopathological correlations were made.

Compared with osteosarcoma of bone, primary osteosarcoma of the soft tissue is very rare. Extraskeletal osteosarcoma is also a highly malignant pleomorphic sarcoma composed of cells exhibiting primarily osteoblastic, and to a lesser extent, chondroblastic differentiation. A case of extraskeletal osteosarcoma in the right sole is presented in a 67 year old male. The patient had noticed a progressively enlarging soft tissue mass, during about 14 months. This sarcoma was located in the soft tissues without attachment to the skeleton, as determined by examination of the X-Ray findings. The mass of right plantar portion was simply excised and pathologically confirmed to be an extraskeletal osteosarcoma. The clinical and pathological features of this sarcoma are described, and brief review of the literature is made.

Agenesis of the dorsal pancreas is one of the rare congenital anomalies of the pancreas. Six cases of them have been reported. We have experienced an autopsy case of agenesis of the dorsal pancreas associated with fetal death in the uterus. Grossly, the body and tail of the pancreas and uncinate process were not found and those were partially replaced by adipose tissue. No abnormality was noted in the other organs. Microscopically, pancreatic tissue with autolytic change was identified only in the head portion of the pancreas.

Tumorlet is a rare lesion of disputed origin that was first described by whitwell in 1955, and about one-third of the reported cases have been associated with underlying lung disease. Patient was a 60-year-old female who was admitted with a histroy of chest discomfort and dyspnea. Right lower lobe was partially resected under the clinical diagnosis of the bronchogenic cyst. Grossly, lung tissue around round cystic lesion appeared brown firm and somewhat fibrotic, and showed several scattered ill-defined whitish gray nodules. Microscopically, lung tissue around bronchogenic cyst was partially obliterated by dense fibrous scar tissue. Within this areas of fibrosis, and in the wall of alveolar ducts and respiratory bronchioles, innumerable microscopic tumorlets were found and argyrophilic granules were also demonstrated in scattered tumorlets with Grimelius stain.
