Estrogen receptor(ER) is a soluble form of hormone receptor protein which is located in the nucleus and cytoplasm of a cell is found in 60% of cases of the cells of breast carcinoma. Fifty to sixty percent of ER positive breast carcinoma responds to antihormone therapy wheres the response rate is only 5% in ER negative tumors. Currently, the ER assay has become a standard index in the management and prediction of the prognosis of advanced breast carcinoma. Semiquantitative biochemical assay, dextran-coated charcol(DCC) assay, to measure ER from fresh tissue was first developed by Korenman in 1970 using isotope-labled ertradiol, has been widely utilized. In 1978, Kurzon newly developed immunocytochemical assay(ICA) employing monoclonal antibody against those hormone receptors to detect intracellular localization of ER and progesterone receptor (PR). The results of the assay have been reported by many investigators thereafter. The purpose of this study was to evaluate the hormonal receptors with a monoclonal antibody using an immunoperoxidase procedure to detect both estrogen and progesterone receptors (ER-immunocytochemical assay:ER-ICA and PR-immunocytochemical assay:PR-ICA) in 59 cases of paraffin embedded sections from formalin-fixed and routinely processed breast carcinoma tissue. Concomitantly, fine-needle aspiration biopsy cytology of the breast cancer from 29 women were assayed for ER/PR receptors. Results were compared with quantitative biochemical values determined from dextran-coated charcoal(DCC) assay on the fresh tumor tissue obtained subsequently from the surgery. ER-ICA showed positive result in 22 out of 36 DCC-positive cases(sensitivity, 61.1%) and negative in 23 out of 23 DCC-negative cases (specificity, 100.0%). PR-ICA was positive in 33 out of 35 DCC-positive cases(sensitivity, 94.3%) and negative in 16 out of 24 DCC-negative cases(specificity, 66.7%). The value of ER-ICA or PR-ICA positivity were roughly correlated with the concentration of ER/PR receptors analyzed by DCC method. The results of both methods were correlated with the nuclear grade of the tumor(ICA:p=0.002, DCC: p=0.015) but were not correlated with histologic grade(ICA: p=0.323, DCC: p=0.0164). ER-ICA positivity was correlated with lower incidence of axillary node metastasis (p=0.021) but no significant correlation between PR-ICA positivity and node metastasis(p=0.171). Both ER/PR-ICA positivity were not correlated with age(p=0.924) and tumor size(p=0.663). The score of ICA particularly ER was proportional to DCC level(ER: r=0.5, p=0.000, PR: r=0.2, p=0.000). ICA concordance with DCC of ER and PR were 76.3% and 83.1%, respectively. The concordance of PR-ICA and DCC was proportional but was statistically less significant. In aspiration biopsy cytology the concordance of ER/PR-ICA and DCC were 72.4% and 65.5%, respectively. Immunocytochemical staining to identify ER/PR receptors from the tissue of breast carcinoma would be tested as a mean to substitute for the conventional DCC method.

Cancer of the alimentary tract in children is an extremely rare occurence, and it accounts for no more than 5% of all pediatric neoplasms. Malignant neoplasms of the stomach are particularly uncommon in childhood. The majority of such lesions are malignant lymphomas or soft tissue sarcomas, with less than 5% identified as carcinomas. We report a case of signet ring cell carcinoma of stomach in 15-year-old girl. This patient had a clinical manifestation of cough with sputum, fever, abdominal distension due to ascites, hepatomegaly, and cervical lymphadenopathy for 40 days. There was no known gastrointestinal symptoms. Metastatic signet ring cell carcinoma was suspected by aspiration biopsy cytology of cervical lymph node, and confirmed later by excisional biopsy. Endoscopy confirmed a small mucosal erosion in the anterior wall of the antrum and histopathology confirmed the diagnosis of signet ring cell carcinoma.

Brenner tumors constitute about l.5~2.5% of all primary ovarian neoplasms and are almost always benign. It appears to derive from the surface epithelium of the ovary which undergoes metap1asia to form the urothelial-like components. we experienced a case of malignant Brenner tumor with adenocarcinoma and squamous cell carcinoma patterns in a 57-year-old woman. It was partly cystic tumor and contained a 4cm-sized gray yellow, lobulated or papillary solid mass, projecting from the cystic wall. Ultrastructurally, the solid mass was composed of malignant urothelial-like cells with focal glandular differentiation.

Mutation of p53 tumor suppressor gene is now recognized as the most frequent genetic alteration in human neoplasms. Although meningiomas are common intracranial tumors, little is known about the clinical significance of p53 abnormalities in meningiomas. We studied 31 cases of meningioma to investigate the significance of p53 protein expression in meningiomas and its relationships with histological and clinical parameters and proliferative activity. Classical and atypical meningiomas were 16 (51.6%) and 15 cases (43.4%), respectively. p53 protein expression was detected in 4 (25.0%) of 16 classical, and 12 (80.0%) of 15 atypical meningiomas. p53 protein expression was correlated with Ki-67 staining index, atypical type, high histologic score, sheet pattern of the neoplastic cells, vascular proliferation, and male patient (p<0.05). In conclusion, immunohistochemical evaluation of p53 protein and histologic score of meningiomas are useful in assessing the prognosis.

The anatomical structure of vermiform appendix was studied for 124 Korean adult cadavers and the articles were reviewed with special reference to its position and length. The results are as follows ; 1. On the frequency of positional types based on Wakeley (1933), postileal type was recorded most frequently (37.7%) and retrocecal type was found in 19.7% of cases, showing the difference from other ethnic groups whose most frequent position was retrocecal or pelvic type. 2. In the direction of appendix in relation to the clock, the direction between 1 and 3 o'clock was most frequently found. 3. Appendix of fixed form was found in 22.1% of cases, that of free form 77.9%. In free form, postileal type was found most frequently, but retrocecal type was met most frequently in fixed form. 4. The length of appendix was 5.95±1.64 cm (male ; 6.14±1.67 cm ; female 5.59±1.51 cm). Neither significant difference between sex nor positional type was noted. 5. Positions of appendix are seemed to be set up during fetal stage. The Ethnic variation in the positions of appendix is thought to be determined by inherited physical anthropological factor, not by postnatal one.

Tracheal gaenesis is an extremely rare congenital anomaly and is characterized by totally or partially undeveloped trachea. In many instances, the lesion has been associated with malformations in other organ systems. This anomaly is classified into 3 types based on developmental period of the respiratory tract. We report a case of tracheal agenesis with tracheoesophageal fistula in a 2-hour-old male. Postmortem examination revealed that the upper and mid portion of the trachea was absent but 1 cm segment of the trachea above the carina was present. The proximal end to this trachea opened to the esophagus by a fistula, 1 cm in diameter. The well-formed larynx ended blindly in a fibrous sac at which thyroids and cartilage islands are noted. Associated anomalies were bilobed right lung and single umbilical artery.

This is a retrospective review of fine-needle aspiration cytology(FNAC) smears of 153 cases of thyroid disease performed during August 1989 to July 1995, which were confirmed histologically following surgical operations. FNAC results showed 63 cases(41.2%) of adenomatous goiter, 45 cases(29.4%) of papillary carcinoma, 29 cases(19.0%) of follicular neoplasm, 4 cases(2.6%) of follicular variant of papillary carcinoma, 4 cases(2.6%) of Hashimoto's thyroiditis, 4 cases(2.6%) of Hurthle cell neoplasm, 2 cases(1.3%) of medullary carcinoma and one case(O.7%) each of subacute thyroiditis and of anaplastic carcinoma. The overall accuracy of cytological diagnosis was 83.7%. These data strongly suggest thyroid FNAC is a reliable preoperative diagnostic tool, but FNAC has been less valuable in the diagnosis of follicular lesions than any other disease of the thyroid. Adenomatous goiter was not infrequently interpreted as follicular neoplasia that requires surgery for diagnostic .conformation and vice versa. The following findings are considered to be compatible with follicular neoplasm: 1) microfolticles, 2) nuclear grooving, 3) irregularity of nuclear membrane, and 4) irregular arrangement or crowding of follicular cells in groups. The FNAC criteria of adenomatous goiter are as follows: 1) atrophic follicular cells, 2) presence of macrophages, 3) abundant colloid, and 4) large follicles. It is recommended that aspiration of thyroid lesions in order to analyse with critical clinico pathological approach and surgery is considered only for nodules that are clinically suspicious or unresponsive to hormone therapy or when a diagnosis of follicular neoplasm is made.

In the past, parasitic diseases were a major problem in public health in Korea. In recent years, however, nematodiasis that used be prevalent are no longer a serious problem. Instead some cestodiasis, particularly cysticercosis and sparganosis have become comparatively more important in recent years. Parasitic infestation of soft tissue is presented as a subcutaneous nodule or mass with nonspecific clinical manifestations.

Rudimentary meningoceles represent a developmental anomaly in which meningothelial elements are found in the skin. The majority of rudimentary meningoceles occur on the scalp over the occiput or along cranial suture lines. They are present as a pink papule, nodule or an area of alopecia. Histologically, the lesion consists of scattered foci of meningothelial cells, an anastomosing network of empty spaces with psammoma bodies and collagen bodies, and small vessels, which may be located from the dermis to the subcutis. Immunohistochemically, the meningothelial cells are commonly positive for vimentin and often positive for EMA. We report the cases of two infants who were noted at birth to have scalp hair anomalies. One had a translucent, bald, slightly atrophic patch on the midline of the vertex and the other had a subcutaneous nodule surrounded by long hairs, so called "hair collar sign" on the midline of the occipital area. The latter had an underlying skull defect without a communication with intracranial spaces. Due to the occasional presence of connection to the central nervous system, any midline lesion in an infant, including rudimentary meningocele, deserves careful preoperative evaluation including imaging studies.
