Fine needle aspiration biopsy cytology (FNA) for diagnosis of a variety of breast tum- ors has been proven to be a simple, safe, and cost saving diagnostic methodology with high accuracy. Cytologic specimens from 1,029 fine needle aspirations of the breast during last 3-year period were reviewed and subsequent biopsies from 107 breast lesions were reevaluated for cytohistological correlation. FNA had a sensitivity of 81.6% and a specificity of 98.3%. One out of 107 cases bio- psied revealed a false positive result (0.9%) and the case was due to misinterpretation of apocrine metaplastic cells in necrotic backgound as malignant cells. A false negative rate was 8.4% (9 of 107 cases biopsied). Six of 9 false negative cases were resulted from insufficient aspirates for diagnosis, and remaining three of 9 false negative cases revealed extensive necrosis with no or scanty viable cells on smears. The results indicate that for reducing false positive and false negative rates of FNA, an experienced cytopathologist and a proficient aspirator are of great importance.

Infantile hypertrophic pyloric stenosis (IHPS) is known to be prevalent in full-term babies, and relatively rare in prematures. The diagnosis of IHPS in premature infants may be obscured because of the lack of classical symptoms and signs and the absence of the standard criteria for ultrasonic diagnosis. The purpose of this study is to discover the clinical differences of IHPS between premature and full-term infants with pyloric stenosis, and to determine the appropriate diagnostic methods for early diagnosis in prematures. The clinical records of 52 IHPS patients who had been operated from October, 1994 to April, 1997 were reviewed. IHPS in premature infants was 25%. The onset of symptom was 4.7 weeks of age in premature, and 2.9 weeks in full-term babies. Diagnosis was established by typical symptoms, signs, and diagnostic imaging studies. In two premature infants, diagnosis was confirmed by upper gastrointestinal (GI) series, because ultrasonography did not meet the diagnostic criteria. Two premature infants diagnosed as gastroesophageal reflux by esophagography initially, were confirmed to have IHPS by upper GI series. For the diagnosis of IHPS, a new set of criteria for premature babies has to be developed.

A 52-year-old women, suffering from generalized pruritus due to intrahepatic and common hepatic duct stones, was treated with astemizole, 30mg daily. Sixty one days later, convulsions and syncope developed suddenly during hospitalization. She had no history of arrhythmia, heart disease, electrolytes imbalance, or CNS disorders. As another case, a 44-year-old man suffering from pruritus due to liver cirrhosis, was treated with astemizole, 30mg daily. Thirty two days later, palpitations and syncope also developed suddenly during hospitalization. He was diagnosed liver cirrhosis, 3 years ago and there was no history of arrhythmia, heart disease, electrolytes imbalance, or CNS disorders. Administration of astemizole was stopped immediately. The laboratory investigations revealed the normal range of serum potassium, calcium and magnesium in both cases. The ECG finding showed the prolongation of QTc interval, frequent VPCs and intermittent polymorphic drugs. On 1st and 3rd day, after discontinue of astemisole, the ECG abnormalities disappeard. It is suggested that astemizole overdose can induce prolongation of QTc interval and torsade de pointes, especially in the patient with liver disease.

Neurilemmoma or Schwannoma is a arising from the sheath of Schwann and is embryologically derived from the neural crest. It is usually solitary and may be benign or malignant, solid or cystic. encapsulated or diffuse. We report a rare case of benign neurilemmoma (Antoni A type) of the penis in a 20 year-old male, and the relevant literature was reviewed.

We report a case of herniated lumbar disc with sequestrated fragments which were located posterior and lateral to the thecal sac. A 60-year-old woman developed lumbago and sciatica one year prior to presentation and acute exacerbation occurred recently. Magnetic resonance imaging showed a mass that was located posteriorly and laterally to the dural sac at the L3-4 level. Laminectomy at L3-4 was done and several fragments were easily separated from the left posterolateral and posterior aspect of the dural sac. Microscopic evamination revealed disc fragment.

In our preliminary study to find antiviral or antitumor agents from Korean natural products, we found that the Shope fibroma virus (SFV) induced fibromas reaching maximum size at 5~6 days with spontaneous disappearance at 15~20 days after SFV intracutaneous inoculation into Korean domestic rabbits. However, the sizes of fibromas of rabbits at day 5 after virus inoculation were significantly different individually. Assuming that the variation of tumor size was due to either susceptibility or the preexisting antibodies against SFV in the Korean domestic rabbits, the rabbits were checked for the antibodies against SFV by IFAT using SFV infected RKl3 cells. The antibody positive rate of normal Korean domestic rabbits was 32.8% and the sizes of the fibromas of the positive rabbits were significantly smaller than those of negative rabbits (p<0.0001). The fibroma sizes were dependent on the antibody titers of rabbits to SFV. The sizes of fibromas after inoculation of SFV into immunized rabbits were about one tenth of those by the first inoculation into normal rabbits. This is the first report on the antibody prevalence against SFV among normal Korean domestic rabbits and it suggest the existence of a wild fibroma virus or related virus in Korea.

Human tail is a rare congenital anomaly in which a lesion protrudes from the lumbosacrococcygeal region. We encountered a case of human tail involving an intradural lipoma and tethered cord, occurring in a 1-day -old female who presented with an 8 cm-sized tail shown by MRI to arise from the S3-4 level. The cauda equina and film terminale were entrapped by the lipoma, but there were no bony abnormalities.
