Islet cell neoplasms (ICNs) of pancreas are uncommon, and the cytologic features of ICN are not well delineated. We report a case of islet cell tumor with lymph node metastasis, describing the cytologic, histologic, and immunohistochemical findings. A 40-year-old woman was admitted due to upper gastrointestinal bleeding of 2 days' duration. Computed tomography of the abdomen showed a diffusely infiltrating bulky mass in the body and tail of the pancreas. The fine needle aspirate showed moderate to high cellularity, monotonous cell population, single ceil predominance over small cell clusters, and eccentrically located nuclei. Although the definite diagnosis of ICN on the cytologic basis is difficult, the cytomorphologic features are sufficiently distinctive to suggest the diagnosis.

동축선 프로브법을 사용하여 매질의 광대역 복소 유전율 값을 얻는다. 신뢰할 수 있는 복소 유전율 분포를 얻기 위해서는 먼저 측정된 반사계수의 정확성과 환산 모델의 안정성이 보장되어야 한다. 본 논문에서는 서로 다른 uncertainty를 갖는 계측기를 사용하여 환산 모델의 민감도를 해석하였다. 그리고 측정된 반사계수의 정확성에 영향을 주는 여러 요인에 대해 측정을 통해 조사하였다. Complex permittivities of material in a wide bandwidth are measured by using an open-ended coaxial probe. To obtain a confident complex permittivity profile, the accuracy of measured reflection coefficients and the stability of the conversion model should be guaranteed in advance. In this paper, the sensitivity of our conversion model is analyzed by employing two instruments with different uncertainties. And various factors effected on the accuracy of measured reflection coefficients are investigated in experiment.
자궁경부 세포진에서 ASCUS 진단의 세분화 - "ASCUS, R/O HSIL" : 세포학적 소견 및 조직학적 상관성

Cytologic and histopathologic features and human papillomavirus (HPV) DNA detection associated with 101 cervicovaginal smears which are ciassified as 'atypical squamous cells of undetermined significance, rule out high grade squamous intraepithelial lesion(ASCUS, R/O HSIL)' were reviewed and compared to 89 smears of 'ASCUS, not otherwise specified(NOS)'. Cytologic fieatures of ASCUS, R/O HSIL included atypical single small cells(36.6%), hyperchromatic tissue flagments(35.6%), atypical metaplastic cells(18.8%), endometrial cell-like clusters(5.9%), and atypical parakeratotic cells(3.0%). A final diagnosis of HSIL on biopsy was assigned to 47(54.0%) of 87 women with ASCUS, R/O HSIL and to 13(14.6%) of 89 women with ASCUS, NOS (p=0.000). There was no difference in HPV DNA detection late between ASCUS, R/O HSIL and ASCUS, NOS smears. These data suggest that subclassification of ASCUS is helpful to manage patients because ASCUS, R/O HSIL is more often associated with an underlying HSIL on biopsy. Therefore, women with ASCUS, rule out HSIL should be actively managed with colposcopic examination.

Papillary immature metaplasia (PIM) of the uterine cervix (Immature condyloma) is a subset of low grade squamous intraepithelial lesion (LSIL) which is frequently associated with human papilloma virus (HPV) types 6 and 11. The histologic features of PIM include filiform papillae lined by evenly spaced immature metaplastic-type cells with frequent nucleoli, mild anisokaryosis, and a low mitotic index. To characterize the cytologic changes associated with PIM, we analyzed 14 cases of PIM from our file. We reviewed biopsy slides and the cervicovaginal smears taken proximate to the time of blopsy. Histologically, nine cases had either flat condyloma (7 cases) or high grade squamous intraepithelial lesion (HSIL) (2 cases). Cytologic changes included cells in various stages of maturation with karyomegaly (14 cases), cells with irregularities in the nuclear membrane (13 cases), intermediate cells with karyomegaly(13 cases), cells with binucleatlon (13 cases), and aborted koliocytes (11 cases) Cervicovaginal smears from all cases were interpreted as atypical squamous cells of undetermined significance (ASCUS), NOS or ASCUS, rule out squamous intraepithelial lesion (SIL) or LSIL in two cases with flat condyloma or HSIL in a case with severe dysplasia. PIM is a distinct histologic entity that can present with a spectrum of cytologic findings, but cytologic findings may resemble variable reactive conditions and immature HSIL. Therefore, it is difficult to diagnose PIM by cytology alone. However, the meticulous efforts for making the cytologic diagnoses which can Induce active management of patients are recommended because PIM is a variant of LSIL and frequently has a flat condyloma or HSIL.

Four cases of primary transitional cell carcinoma (TCC) arising in the ovary (3 cases) and the parovarium (1 case) were collected for clinicopathologic analysis. The mean age was 46.2 years (range, 39-57 years). Two patients complained abdominal discomfort and vaginal discharge, respectively. Other 2 cases were incidentally found from routine check. Grossly, the tumors were solid and cystic (2 cases), solid (1 case) and surface papillary growth on capsule (1 case). Microscopically, the tumor showed almostly same to the histologic features of TCC of urinary bladder. Three cases were pure TCC, and one was mixed TCC and serous carcinoma. FIGO stage were 1 IIa, 2 IIc, and 1 IIIc. Treatment was surgery with adjuvant chemotherapy. Two patients are alive with no evidence of disease, and two have lung or brain metastasis.
