Human embryology is the study of development from a single cell to a baby in 9 months. Implantation occurs at the end of the first week of development. The second week of development is known as the week of 2’s. Gastrulation, the most characteristic event occurring in the third week, establishes three germ layers composed of ectoderm, mesoderm, and endoderm. The three germ layers and neural crest cells lead to the development of their own tissues and organs during the embryonic period, which extends from the third to the eighth week. Major congenital malformations occur in the embryonic period. The fetal period, from the third month to the day of birth, is the time for maturation of tissues and organs, and growth of the body. Because of the close relationship between embryology and congenital abnormalities, knowledge of human development is essential to assess the effects on the embryo when the mother has been exposed to teratogens. This paper briefly reviews the normal embryonic development and associated congenital malformation.

Postmenopausal squamous atypia (PSA) is a phenomenon characterized by cellular alterations mimicking condyloma in the uterine cervix of postmenopausal women. It is not associated with human papillomavirus (HPV) infection. The aim of this study is to correlate findings with HPV infection and the cytohistologic findings of PSA. Eighty-three smears from postmenopausal women, initially interpreted as ASCUS and low-grade squamous intraepithelial lesions(LSIL), were reviewed according to the criteria of PSA. Fifty-eight cases were subsequently reclassified as PSA. Forty cases categorized as PSA were available for HPV-DNA detection by a nested polymerase chain reaction. Eight of these 40 cases(20%) showed biopsy-proven LSIL lesions. The HPV-DNA was detected in 42.5%(17/40), compared to 25%(5/20) of control cases. The HPV-DNA detection rate of biopsy-proven LSIL was 62.5%(5/8). It has been concluded that cytologic differential diagnosis of PSA from LSIL is difficult due to because of poor histologic and viral correlation.

Medullary carcinoma (MC) of the breast is an uncommon histologic form of infiltrating ductal carcinoma and the cytologic features of MC are not well delineated. We recently experienced a case of fine needle aspiration cytology of MC of the breast. The characteristic cytopathologic features were cellular aspirate consisting of large, pleomorphic cells in background of many single to clusters of lymphocytes.
Neuroendocrine Tumors of the Female Reproductive Tract: A Literature Review
전이경 대한병리학회 2015 Journal of Pathology and Translational Medicine Vol.49 No.6
Neuroendocrine tumors of the female reproductive tract are a heterogeneous group of neoplasms that display various histologic findings and biologic behaviors. In this review, the classification and clinicopathologic characteristics of neuroendocrine tumors of the female reproductive tract are described. Differential diagnoses are discussed, especially for non-neuroendocrine tumors showing high-grade nuclei with neuroendocrine differentiation. This review also discusses recent advances in our pathogenetic understanding of these disorders.

We report two autopsy cases that revealed the partial absence of the septum pellucidum with ventriculomegaly. In each case, the brain showed mild dilatation of both frontal horns of the lateral ventricles, normal third and fourth ventricles and no aqueductal stenosis. The posterior portion of the septum pellucidum was absent and the fornices were fused in a single midline nodule, abnormally displaced to a caudal position and lodged in the foramina of Monro. The brain base showed no apparent abnormalities;the optic nerves were well developed. We conclude that the caudally displaced fornix in the absence of the septum pellucidum may have intermittently obstructed the foramina of Monro and induced mild ventriculomegaly.

Urine cytology is of limited value in the diagnosis of renal cell carcinoma with reported detection rates of $0\sim80%$. The aim of this study is to demonstrate the usefulness of urine cytology in renal cell carcinoma. In the eleven histologically proven cases of renal cell carcinoma, urinary smears were reevaluated. The cytologic results were as follows; positive for malignant cells in 3 cases(27%), suspicious in 2 cases(18%) and negative in 6 cases(55%). The average diameter of the tumor of the 5 cases reported as positive or suspicious for malignant cells was 9.7cm and 3 had invaded the renal pelvis. The other 6 tumors, reported as negative, were 5.7 cm in average diameter and one of them showed involvement of the renal pelvis. These results suggest that urine cytology is considered unsatisfactory in the early defection of renal cell carcinoma. However, careful examination of urinary smear could improve the detection rate especially in more advanced cases involving the renal pelvis as well as those of larger tumors.
자궁내 발달지연과 정상 말기임신 태반에서의 Telomerase 활성도와 MIB-1 및 Fas, Fas Ligand 발현차이에 관한 연구
전이경,홍성란,양문호 대한병리학회 2005 Journal of Pathology and Translational Medicine Vol.39 No.1
Background : The placenta from a pregnancy that is complicated by intrauterine growth retardation (IUGR) tends to be smaller than that from a normal pregnancy. To investigate this difference, we analyzed the telomerase activity, the proliferative activity and the mRNA levels of apoptosis mediators in placentas. Methods : In 20 placentas from normal third-trimester pregnancies and 22 placentas form pregnancies that were complicated by IUGR, the telomerase activity was detected by a telomeric repeat amplification protocol assay. The proliferative activity was assessed by immunohistochemical staining using the MIB-1 monoclonal antibody. The expression of the apoptosis mediator was evaluated by semi-quantitative reverse transcription-polymerase chain reactions for fas and fas ligand. Results : Telomerase activity was detected in 2 (10%) of 20 normal placentas, whereas it was not observed in all tested 13 placentas that were associated with IUGR. The proliferative activity was significantly low in the placentas that were associated with IUGR (7.44 2.96%), compared with the normal placentas (11.0 3.48%, p=0.002). There was no statistically significant difference in the mRNA levels of fas or fas ligand between two groups. Conclusions : Low telomerase and proliferative activities in the placenta may play a role in the pathogenesis of IUGR.

Due to insufficient clinical information, most cervicovaginal smears from pregnant or postpartum women have been screened without regard to pregnancy-related cytological changes. Here, we have reviewed 116 abnormal cervicovaginal smears from 103 pregnant and postpartum women. Initial cytological diagnoses revealed the following: 9 cases of high-grade squamous intraepithelial lesions (HSIL), 8 cases of low-grade squamous intraepithelial lesions (LSIL), 85 cases of atypical squamous cells of undetermined significance (ASCUS), and 14 cases involving atypical glandular cells of undetermined significance (AGUS). 31 cases upon review, involved pregnancy-related cytological changes, comprising 25 cases of decidua cells, 4 cases of Arias-Stella reaction, and 2 cases of cedidual cells coupled with Arias-Stella reaction. Interpretation errors were detected in 14 cases: 13 cases of decidual cells interpreted as either ASCUS favor reactive or ASCUS ruled out HSIL, and one case of Arias-Stella reaction was interpreted as ASCUS ruled out HSIL. Decidual cells and degenerated glandular cells with Arias-Stella reaction can result in diagnostic mistakes. In order to avoid misdiagnosis and unnecessary surgeries, both clinicians and pathologists must be aware of the pregnancy-related cytological changes. The clinician should also always inform the pathologist on the pregnancy status of the patient.

Malakoplakia is an uncommon chronic granulomatous inflammation that usually involves the urinary and gastrointestinal tracts, but rarely affects the female genital tract. We experienced a case of malakoplakia in a cervicovaginal smear in a 54-year-old woman. Colposcopic examination showed a friable, easily bleeding tissue in the uterine cervix and the vaginal fornix. The cervicovaginal smear consisted of numerous isolated histiocytes, polymorphonuclear leukocytes, lymphocytes, and plasma cells. The histiocytes had an abundant, granular, and degenerated cytoplasm with inflammatory cell debris. Michaelis-Gutmann bodies were readily identified.
