      • 단순포진 Virus 감염의 세포학적 진단시 면역조직 화학법의 적용

        박혜림,이갑노,백승룡,Park, Hye-Rim,Lee, Kap-No,Paik, Seung-Yong 대한세포병리학회 1990 대한세포병리학회지 Vol.1 No.1

        Herpes simplex virus type 1 and 2(HSV-1, HSV-2) are the ubiquitous human pathogens responsible for a variety of afflictions. HSV-2 is one of the viruses that were suspected of promoting carcinogenesis in the uterine cervix. Certainly, there is a need for the more sensitive and accurate laboratory techniques for HSV detection. We examined total 80 cases of smears including 17 Tzanck smears of skin and 63 cases of Papanicolaou smears from total 77 patients with clinical impression of herpetic infections, from September, 1985 through August, 1989. Immunohistochemical typings for HSV-1 and HSV-2 were performed together with routine cytologic findings and compared. The results are as follows : 1) Patients were 9 males and 33 females, and age distribution was between 5 and 71 years. 2) Subjective symptoms such as ulceration, vesicle, vaginal discharge, pruritus, and pain were complained in 36 patients and 38 cases were genital herpes. Recurrence was noted in 11 cases. 3) Positive results were obtained in 42 among 80 cases. 4) Both routine cytology and immunohistochemical staining were positive in 13 cases and in 24 cases only immunohistochemical staining were positive. 5 cases were positive only in routine cytologic smears. 5) The cases that immunocytochemical stain had been performed were 37 cases, which were all positive in type 2. Among the above 37 cases, type 1 also were positive in 5 cases. The results show that the immunoperoxidase technique is one of the rapid and reliable method to confirm the herpetic infection when suspected and that it is particularly useful when the Papanicolaou smear findings are equivocal.

      • 양성 림프절 증식의 세침흡인 세포검사의 감별진단

        In the investigation of superficial lymphadenopathy of unknown cause, fine needle aspiration (FNA) cytology plays an invaluable role. It enables the differentiation of benign lymphadenopathy from lymphoid and non-lymphoid malignancies, obviating the need for open biopsy, and allowing the triage of patients. Cytopathologists should be familiar with the typical FNA patterns of benign lymphadenopathy, and recognize and differentiate among categories. In a minority of cases of benign lymphadenopathy, FNA can render a specific diagnosis. Benign lymphadenopathies are generally categorized into reactive lymphoid hyperplasia (RLH), inflammatory or infectious processes, and benign lymphoproliferative disorders. RLH characteristically presents with a heterogeneous and polymorphous smear composed of normal cellular constituents of lymph nodes, in contrast with the homogeneous or monomorphic smear of most lymphomas. The caveat is that various malignant disorders may also present with polymorphous populations. It is also important to recognize thatbenign lymphoid smears may sometimes contain atypical cells that raise the suspicion of malignancy. Clinical information should always be the integral part of the diagnostic criteria in FNA of lymphadenopathy. If there is any doubt about the benign nature of the smear, it is prudent to suggest biopsy and ancillary studies.

      • 갑상샘 유두암종의 세포진단에서 형태학적 계측의 분석

        The diagnosis of papillary thyroid cancer is generally based on the findings of intranuclear cytoplasmic inclusions and nuclear grooves. Although anisokaryosis and poikilokaryosis, in papillary thyroid cancer, are not distinct when compared to other cancers, cytological examination can provide useful preoperative information. Our study evaluated the diagnostic role of computer-assisted image analysis for the pre-surgical assessment of papillary thyroid carcinoma. Thyroid aspirates from twenty female patients who were histologically confirmed to have both papillary carcinoma and benign nodules were studied. Different populations of 50 benign cells and 50 malignant cells were analyzed. Five morphometric parameters were selected for analysis: nuclear area, perimeter, maximum length, maximum width and intensity standard variation. The values obtained for papillary carcinomas were higher than the surrounding benign nodules as follows: nuclear area 63.5 vs. 36.1 (p=0.000), nuclear perimeter were 29.4 vs. 22.0 (p=0.000), maximum length 9.6 vs. 7.1 (p=0.000), maximum width 8.2 vs. 6.3 (p=0.000), the ratio between maximal length and maximal width 1.16 vs. 1.13 (p=0.000), the standard variation of intensity 14.9 vs. 15.9 (p=0.101) respectively. Therefore, morphometric information can be helpful for the differential cytological diagnosis of papillary thyroid carcinoma.

      • 세침흡인 세포검사에서 폐의 소세포암종과 샘암종의 감별진단

        Distinguishing small cell carcinoma from other lung malignancies is of great clinico-therapeutic significance. Small cell carcinoma is an aggressive tumor with a tendency to metastasize early. Survival time if untreated is low but this tumor is highly responsive to chemotherapy. We have occasionally experienced difficulties in differentiation between adenocarcinoma and small cell carcinoma of the lung in fine needle aspiration cytology (FNAC). The aim of this study was to investigate the possibility of distinguishing small cell carcinoma from adenocarcinoma of the lung in FNAC. We evaluated cytomorphological features of FNAC specimens from 62 small cell carcinomas and 57 adenocarcinomas from the lung that were confirmed by biopsy and/or immunohistochemistry on cell block. Cytomorphological details of the two tumors were compared. Nuclear smearing and nearly absent cytoplasm were the most distinct findings in small cell carcinoma compared to adenocarcinoma (p<0.05). Necrotic background, architecture and chromatin pattern, nuclear molding and nucleoli were significantly different (p<0.05). Nuclear size, nuclear membrane nature and nuclear size variation however were not helpful in distinguishing the two tumors. Combining several features described above, small cell carcinoma can be properly differentiated from adenocarcinoma on FNAC. FNAC is proposed as a diagnostic tool of small cell carcinoma of the lung in the case of inaccessibility to biopsy, and so may allow the proper therapeutic strategies to be determined in such cases

      • 자궁목 융모샘 샘암종의 세포 소견 -2예 보고-

        Villoglandular adenocarcinoma of uterine cervix has recently been described, and is characterized by good prognosis and occurrence in young women, except a small number of cases. Morphologically, it exclusively shows villoglandular growth and mild to moderate nuclear atypia, the cytologic diagnoses have been frequently missed due to interpretation error. We report here on the cytologic findings of two cases, and both cases were not diagnosed as adenocarcinoma before punch biopsy. One of these cases showed previously described characteristic features such as high cellularity and large tissue fragments with long villous fronds lined by columnar cell with mild nuclear atypia. The other showed moderate cellularity of somewhat smaller clusters without long villous structures. The clusters showed marked nuclear overlapping and the nuclei showed distinct moderate atypia with hyperchromasia and coarse chromatin pattern. The nucleoli were indistinct. Recognition of these features will be helpful to avoid underdiagnosis as a benign lesion, although diagnosis is still difficult in a portion of the cases.

      • Merkel 세포 암종의 동결절편진단에 있어 접착도말의 유용성 -1예 보고-

        Merkel cell carcinoma (MCC), a rare primary cutaneous small cell neuroendocrine carcinoma, is a tumor with distinct cytological features. In many cases, immunohistochemical staining (IHC) is required for the differentiation from other small round cell malignancies. Here we describe the cytological findings of Merkel cell carcinoma; these findings contributed to the diagnosis prior to performing IHC. A lower eyelid mass was excised and submitted for frozen section diagnosis. The frozen section diagnosis was consistent with a malignancy, but the more specific diagnosis was limited by the lack of specific histological features. Touch imprint cytology revealed a high cellularity with loosely cohesive small to large sized cells. The tumor cells showed hyperchromatic nuclei with fine chromatin and inconspicuous nucleoli, and thin-rimmed-cytoplasm including the characteristic eosinophilic button-like paranuclear inclusion, previously described as a pathognomonic cytological finding of MCC; this was not found in the H&E frozen section. In conclusion, we suggest that the touch imprint cytology may help in the differential diagnosis of small round cell neoplasms prior to performing IHC especially in frozen section diagnosis.

        Recently, we experienced a case of Angioimmunoblastic T-cell lymphom (AITL) in a 60-year-old man presented with lymphadenopathy, which is first cytological report in Korea. The cytological features showed a heterogeneous population of small to medium-sized lymphocytes, immunoblasts, and plasma cells. Characteristically, there were also a distinct population of follicular dendritic cells admixed with lymphoid cells, forming the so-called dendritic cell-lymphocyte complexes. Histological features showed the classic morphologic features of AITL. Recognition of the characteristic cytological features can suggest the possibility of AITL.

        Fine needle aspiration has been widely used to diagnose of breast lesions whether they are malignant or not. When applied by experienced and well-trained practitioners, its accuracy can approach that of histopathology. In order to make optimal use of FNAB in breast lesions, this article has reviewed the criteria for sample adequacy, the diagnostic terminology and the cytomorphologic approach to making a diagnosis and avoiding diagnostic pitfalls.

        The authors present the fine needle aspiration cytology (FNAC) cytologic findings of a case of extranodal marginal zone B cell lymphoma (MZBCL), which featured abundant plasma cells and eosinophilic histiocytes arising in both parotid glands. A 49-year-old female presented with palpable masses in both parotid glands. She had been suffering from systemic lupus erythematosus and rheumatoid arthritis. The lesions were evaluated by FNAC and smears showed a small number of clusters of oncocytic cells with abundant eosinophilic granular cytoplasm and small nuclei, intermixed with small to medium-sized lymphoid cells containing round to lobulated nuclei, which suggested Warthin's tumor. Some of lymphoid cells had a plasmacytoid appearance, and some scattered large cells contained a large amount of eosinophilic cytoplasm. Bilateral superficial parotidectomy was performed and a histopathologic study indicated MZBCL with abundant plasma cells, intermixed with eosinophilic histiocytes. The presence of oncocytic cells and a mixture of lymphoid and plasma cells indicates Warthin's tumor, but the cytologic features of a relatively monotonous small to medium-sized lymphoid infiltrate suggest the possibility of MZBCL in the clinical setting of an FNAC study performed on a patient suffering from a connective tissue disease.
