Abstract PDF: The Bethesda System (TBS) was first developed in 1988 for the need to enhance the communication of the cytopathologic findings to the referring physician in unambiguous diagnostic terms. The terminology used in this reporting system should reflect current understanding of the pathogenesis of cervical/vaginal disease, so the framework of the reporting system should be flexible enough to accommodate advances in medicine, including virology, molecular biology, and pathology. Three years after the introduction of TBS, the second Bethesda workshop was held to set or amend diagnostic criteria for each categories of TBS. TBS 1991 is now widely used. The third Bethesda workshop, The Bethesda System 2001 Workshop, was held in National Cancer Institute, Bethesda, Maryland from April 30 to May 2, 2001. Again, the goals of this workshop were to promote effective communication and to clarify in reporting cervical cytopathology results to clinicians and to provide with the information to make appropriate decisions about diagnosis and treatment. Nine forum groups were made and there were Web-based bulletin board discussions between October, 2000 and the first week of April, 2001. On the basis of bulletin board comments and discussions, the forum moderators recommended revised terminologies in the Workshop. Hot discussions were followed after the presentation by forum moderators during the workshop. Terminologies confusing clinicians and providing no additional informations regarding patient management were deleted in the workshop to clarify the cervicovaginal cytology results. Any informations related to the patient management were encouraged to add. So 'Satisfactory for evaluation but limited by' of 'Specimen Adequacy' catergory was deleted. Terminology of 'Unsatisfactory' was further specified as 'Specimen rejected' and 'Specimen processed and examined, but unsatisfactory'. Terminologies of 'Benign Cellular Change' and 'Within Normal Limits' were combined and terminology was changed to 'Negative for intraepithelial lesion

Abstract PDF: To evaluate the role of sputum and bronchial washing for the diagnosis of lung carcinoma, we studied the sensitivity of both cytologic techniques using the biopsy confirmed cases from 228 patients. Among them, 123 cases were squamous cell carcinomas, 42 cases were adenocarcinomas, 48 cases were small cell carcinomas, one case was large cell carcinoma, and 14 cases were other types of carcinoma including poorly differentiated carcinomas. Three hundreds and ninety two sputa and 173 sputa were obtained in the pre- and post- bronchoscopic periods. Bronchial washing had been taken once in each patient. The overall sensitivity of the sputum cytology was 0.52 and that of the bronchial washing 0.63, while it increased to 0.83 when a combination of both techniques. Squamous cell carcinomas were diagnosed to the great extent in which sensitivities were 0.59 and 0.74, in sputum and bronchial washing, respectively. The post-bronchoscopic sputa showed higher sensitivity (0.44) than pre-bronchoscopic sputa (0.30). The sensitivity of sputa increased from 0.34 to 0.49 when three samples were examined compared to the single examination. The accuracy of cell typing was 94.0% in sputa and 93.8% in bronchial washing. Repeated sputum examination including post- bronchoscopic sputa is warranted to improve sensitivity and a complementary role of both cytologic techniques can be postulated by these data.

Abstract PDF: Tuberculous lymphadenitis is not uncommon in Korea. Therefore, an inexpensive, safe and rapid method is needed to diagnose the tuberculous lymphadenitis. Fine needle aspiration cytology is a good method for this purpose, but has several limitations in the diagnosis of tuberculous lymphadenitis, especially when the presence of acid-fast bacilli is not proved. To evaluate the usefulness of the polymerase chain reaction with enzyme immunoassay technique in the detection of Mycobacterium tuberculosis (M. tuberculosis) in the cervical lymph node aspirates, the authors performed fine needle aspiration cytology and M. tuberculosis PCR with enzyme immunoassay for mycobacterial DNA sequences from 15 cases of the fine needle aspirates. Cytomorphologically, the cases were categorized into three types: predominantly necrotic materials; typical epithelioid cell granulomas with or without giant cells and caseous necrosis; and non-tuberculous lesions, such as reactive lymphadenitis, abscess, metastatic carcinoma and malignant lymphoma. M. tuberculosis DNA was found in 8 of 15 cases by PCR with enzyme immunoassay. Negative findings on PCR were achieved in 7 cases, which revealed non-tuberculous lymphadenopathy. In conclusion, we suggest that M. tuberculosis PCR with enzyme immunoassay using the fine needle aspirates is a very useful tool for the diagnosis of tuberculous lymphadenitis.

Abstract PDF: While cytologic characteristics of squamous dysplasia, carcinoma in situ, and invasive squamous cell carcinoma of the uterine cervix are well documented, relatively few studies have dealt with the cellular features of microinvasive carcinoma. In order to describe the cellular characteristics of microinvasive squamous cell carcinoma, we retrospectively reviewed 45 cervovaginal smears(15 carcinoma in situ, 15 microinvasive cancer, 15 invasive cancer) which were confirmed by histologic examination of specimens obtained by hysterectomy at the Seoul National University Hospital during 5 years from 1995 to 1999. The cytologic features about tumor diathesis, inflammatory background, cell arrangement, anisonucleosis, nuclear membrane irregularity, nuclear chromatin pattern, and nucleoli were observed. The cytologic characteristics of microinvasive squamous cell carcinoma of the uterine cervix are syncytial pattern, mild tumor diathesis, the irregularity of nuclear membrane, irregularly distributed nuclear chromatin, and occurrence of micronucleoli. But, correlation between the depth of invasion and the cytologic feature had limited value.

Abstract PDF: Pleuropulmonary blastoma (PPB) is an unusual intrathoracic blastoma presenting in childhood and characterized by a biphasic neoplastic population of undifferentiated, small round blastemal cells and larger spindle-shaped sarcomatous cells with entrapped benign epithelial-lined structures. We experienced the cytologic features of PPB in imprint smear from the pleural-based huge mass of the middle lobe of the right lung in a 4-year-old boy. The smears showed high cellularity composed of small ovoid blastemal elements and scattered spindle mesenchymal tumor cells. Lobectomy and pathologic investigation confirmed the diagnosis. PPB seems to be a tumor in which accurate diagnosis may be achieved by cytology if appropriate clinical information were given. Timely and accurate diagnosis of PPB by cytology paves the way for attempting preoperative treatment in future cases.

Abstract PDF: Acinic cell carcinoma(ACC) is the third common malignancy in major salivary gland. Fine needle aspiration cytology is a useful tool for the diagnosis of salivary gland lesions. However, some low grade malignancies, such as ACC and mucoepidermoid carcinoma show relatively high false negative rate, mainly due to deceptively benign cytomorphologic appearance. We experienced a papillary-cystic variant of ACC, having different cytopathologic features compared with those of classic ACC. Our case showed monolayered sheets and papillary clusters without any acinic structures or naked nuclei of the tumor cells. Foamy proteinaceous material was seen in the background. The tumor cells had a large amount of granular cytoplasm and eccentric nuclei. Many vacuolated or clear cells were also noted.

Abstract PDF: Salivary duct carcinoma is an uncommon aggressive malignant epithelial neoplasm with similarity to intraductal carcinoma of the breast. This neoplasm occurs most often in the parotid gland of middle-aged and older males. About 7% of reported tumors occured in the submandibular gland. The report of salivary duct carcinoma with calcification is rare. We report a case of salivary duct carcinoma with calcification in the submandibular gland. The patient was a 73-year-old male with a mass of the right submandibular gland for 1 year. On the fine needle aspiration cytology, the aspirate showed scant cellularity, small clusters of tumor cells, and scattered small calcifications. Nuclei of the tumor cells showed mild pleomorphism and round to oval in shape, and cytoplasm was abundant and finely granular. Nucleoli were indistinct and necrosis was not noted. There were no cribriform or papillary arrangements of tumor cells. Cytologic findings of salivary duct carcinoma are variable depending on histologic findings, and calcifications could be an additional cytologic finding.

Abstract PDF: Cytologic features of a case of mantle cell lymphoma is presented, which was obtained by fine needle aspiration cytoloby and confirmed by excisional biopsy of axillary lymph node. A 67-year-old female alleged palpable masses in both axillae for several months. Additional multiple lymphadenopathies were found in the both neck and inguinal areas. The main cytologic feature was carpeting of monotonous slightly atypical small lymphocytes without heterogeneous components. The nuclei of these lymphocytes are slightly larger than benign small lymphocyte and relatively round with some indentation. Nucleolus was not prominent and no mitosis was found. Their cytoplasm was scanty and cyanophilic in Papanicolaou's stain. The histiocytic cells, which had bland-looking banded nuclei and abundant cytoplasm, corresponding to pink histiocytes were shown. Excisional biopsy of lymph nodes was diagnosed as mantle cell lymphoma, diffuse type.

Abstract PDF: Fine needle aspiration cytology of the cervical lymph node was performed in a 63-year-old man who had had an orchiectomy for seminoma one year ago. The tumor cells were arranged in loose clusters, occasional sheets, or single cells. The nuclei were round to ovoid with fine or reticular chromatin, and had one or more prominent nucleoli. These cells were intermingled with lymphocytes in a characteristic foamy, lacelike background. Documented reports of the cytologic appearance of the seminoma are rare, especially in the metastatic lesion. The diagnosis of primary gonadal seminoma by fine needle aspiration cytology is probably not indicated since the treatment of primary gonadal tumor requires surgical resection. Because of the characteristic cytologic features, fine needle aspiration cytology may be helpful in evaluation of the extent of tumor spread in the patients with testicular tumors.

Abstract PDF: A 20-year-old young man who had undergone treatment for a suprasellar/perichiasmal tumor 2 years before, was presented with a huge palpable splenic mass. A fine needle aspiration cytology from the splenic mass showed dissociated large pleomorphic tumor cells having irregular nuclear outline, coarse chromatin, and one or two macronucleoli, and scattered small lymphocytes in fine granular background. Above cytologic findings were regarded as the characteristics of germinoma. Differential diagnosis from the large cell lymphoma of spleen was emphasized.

Abstract: Primary malignant lymphoma of the thyroid gland is uncommon malignancies. Its fine needle aspiration cytology (FNAC) findings are rarely described in the literature. This article highlights the FNAC diagnosis of primary malignant lymphoma of the thyroid gland. A 70-year-old female presented with a rapidly enlarging thyroid mass of five months' duration. FNAC smears showed low cellularity consisting of predominantly atypical enlarged lymphoid cells admixed with a few small lymphocytes, plasma cells, and oncocytic cells. Some disrupted lymphoid cells were also present. The tumor cells infiltrated into the thyroid follicular epithelium forming lymphoepithelial lesion. The cytologic appearance showed a diffuse mixture of cell types with only a few small, mature lymphocytes and many enlarged lymphoid cells. The enlarged lymphoid cells were atypical and pleomorphic with nuclear clefting and irregularities. Grossly, the left lobe of the thyroid was nearly replaced by a diffuse firm to soft solid mass with smooth tan fish-flesh homogeneous cut surface. Histological diagnosis was diffuse large B-cell lymphoma with areas of marginal zone B-cell lymphoma of MALT type.
