BACKGROUND
This study investigated whether human papillomavirus (HPV) genotype is related to koilocytic changes in cervical cytology and histology, and what factors cause discrepancies among cytology, HPV DNA chip tests, and biopsies.
METHODS
We examined 174 of 949 cases histologically confirmed by both cytology and HPV DNA chip testing. We analyzed koilocytic changes in cytology and biopsies according to HPV genotype.
RESULTS
HPV-16 significantly coincided with nuclear size variation and hyperchromasia, although the cytomorphologic features correlated with other HPV genotypes were not statistically significant. By analyzing 68 cases in which there were discrepancies between the HPV DNA chip test and histological results, we confirmed that artifacts or glycogen acanthosis resulted in the over-diagnoses of four HPV-negative cases with normal cytology. Four diagnostic errors and four sampling errors were present in eight HPV-positive cases. The degree of nuclear size variation significantly influenced the cytologically under-diagnosed cases (p=0.006).
CONCLUSIONS
Other than HPV-16, HPV genotype exhibited no cytological or histological differences. The discrepancy between the results of HPV DNA chip test and histology was created by glycogen acanthosis, immature squamous metaplasia, artifacts, and sampling errors.

Abstract PDF

BACKGROUND
Cervicovaginal cytology is a screening test of uterine cervical cancer. The sensitivity of cervicovaginal cytology is less than 50%, but studies of cytologic/histologic correlation are limited. We analyzed the diagnostic accuracy of cervicovaginal cytology in the detection of the squamous epithelial lesions of the uterine cervix and investigate the cause of diagnostic discordance. MATERIALS AND METHODS: We collected a total of 481 sets of cervicovaginal cytology and biopsies over 5 years. The cytologic diagnoses were categorized based on The Bethesda System and the histologic diagnoses were classified as negative, flat condyloma, cervical intraepithelial neoplasia (CIN) I, CIN II, CIN III, or squamous cell carcinoma. Cytohistologic discrepancies were reviewed.
RESULTS
The concordance rate between the cytological and the histological diagnosis was 79.0%. The sensitivity and specificity of cervicovaginal cytology were 80.6% and 92.6%, respectively. Its positive predictive value and negative predictive value were 93.7% and 77.7%, respectively. The false negative rate was 19.4%. Among 54 false negative cytology cases, they were confirmed by histology as 50 flat condylomas, 2 CIN I, 1 CIN III, and 1 squamous cell carcinoma. The causes of false negative cytology were sampling errors in 75.6% and interpretation errors in 24.4%. The false positive rate was 7.4%. Among 15 false positive cytology cases, they were confirmed by histology as 12 atypical squamous cells of undetermined significance (ASCUS) and 3 low grade squamous intraepithelial lesions (LSIL). The cause of error was interpretation error in all cases. The overall diagnostic accuracy of cervicovaginal cytology was 85.7%.
CONCLUSIONS
Cervicovaginal cytology shows high overall diagnostic accuracy and is a useful primary screen of uterine cervical cancer.

Abstract PDF: Localized amyloidosis of the ureter is rare and clinically confused with neoplasm. We describe a case of localized amyloidosis of the ureter in which the presence of amyloid was detected in ureteral washing cytology. A 75-year-old female presented with gross hematuria. Abdominal CT and retrograde pyelography revealed hydronephrosis and hydroureter on the left side with abrupt narrowing of the distal ureter. Ureteral washing cytology yielded a hypocellular smear with many irregular clumps of amorphous, extracellar, waxy material. Biopsy sections demonstrated submucosal deposits of eosinophilic amorphous material which gave characteristic apple green birefringence with Congo-red stain under the polarized light. Familarity with the cytologic features of amyloid is helpful for preoperative diagnosis and proper treatment.

Abstract PDF: We investigated a unilocular mammary cyst occurring in a two and a half year old male baby. The cyst was lined by simple columnar epithelium and filled with a milky secretory material. These histologic features were consistent with galactocele. The child had enlarged left breast since birth, but it seemed to be noncontributory as the child had neither endocrine abnormalities nor perinatal disorders. Galactocele is an uncommon breast lesion usually occuring in females following lactation. It is rarely a cause of breast enlargement.

Abstract: Since the discovery of hepatitis B virus as one of the causes of hepatitis, liver and hepatocellular carcinoma, many hepatitis B viral markers that appear in infected individuals have been discovered and many efforts to understand the relationship between the emergence of viral markers and the progression of hepatitis have been performed. Gudat (1975) compared the expression of HBcAg and HBsAg in various conditions and stages of hepatitis but the pattern of expression of viral markers and its significance have not been understood. Recently it was found by mierocytotoxicity assay that HBcAg might be the target of T lymphocytes. This study attempted to identify any correlation of the tissue expression rate and pattern of HBcAg and HBsAg with the histologic activity of 46 cases of liver cirrhosis using immunohistochemical staining. The expression rate and pattern of HBcAg and HBsAg in relation to the nodular size and positivity of serum HBeAg were also compared. The results were as follows; 1) The expression rate of HBcAg in the liver was 41.3% (19/46). and that of HBsAg was 67.4% (31/46). 2) The histologic activity of liver cirrhosis appeared to be correlated with the expression of HBcAg, especially cytoplasmic HBcAg. 3) The positivity of serum HBeAg was significantly higher in active liver cirrhosis. 4) There was no relationship between the tissue expression of HBsAg and the histologic activity of liver cirrhosis. relationship existed between the nodular size and expression rate and pattern of HBcAg and HBsAg. This study suggests that the tissue HBcAg, especially the cytoplasmic HBcAg is the most likely factor determining the histologic activity of liver cirrhosis, and that the cytoplasmic HBcAg may be the ultimate cause and target of most host immune response.

Abstract: Unstable microsatellite repeat sequences or DNA replication errors(RER) due to defective mismatch repair genes have been reported in a subset of sporadic colorectal tumors and in most tumors of patients of hereditary nonpolyposis colorectal carcinoma(HNPCC). To elucidate the clinicopathological correlation of these RER-positive cancers, we examined 16 cases of colorectal carcinoma of different histologic subtypes(6 cases of carcinoma with no gland formation, 5 cases of mucinous carcinoma and 5 cases of gland forming carcinoma). We detected RER in five cases. The patients with RER-positive cancers had a marked preponderance of carcinoma with no gland formations out of 6 carcinomas with no gland formation were RER-positive cancers) and of cancers proximal to splenic flexure(all of the RER-positive cases were proximal colon carcinomas). We conclude that RER-positive cancers have wiique pathologic features that may be useful for the screening and counselling of patients with hereditary colon cancers.
