We experienced a case of primary hepatic actinomycosis which was initially diagnosed by means of fine needle aspiration. The patient was a 31-year-old emaciated man with a 2-month history of 10 kg weight loss, right upper quadrant pain and flank pain. The liver was palpable and tender on physical examination. Computerized tomography scan of the liver showed two ill-defined hypodense masses in gallbladder fossa and inferior pole of right lobe. Hepatocellular carcinoma was clinically suspected. A CT-guided fine needle aspiration was peformed. Microscopically, smears showed numerous radiating clusters of filamentous bacteria with many neutrophils and monocytes in necrotic background. The symptoms were improved by incision and drainage and massive administration of penicillin.

Leiomyosarcoma of the soft tissue is a well-defined and characteristic entity histologically, but cytomorphological studes are lacking. A correlaive cytological study of 2 cases of leiomyosarcoma is presented. The smears from case 1 were rich in tumor cells and most cells were arranged in large sheets or clusters. The cells showed round to oval nuclei containing fine chromatin and small promiment nucleoli. The smears from case 2 were moderate in cellularity with loose clusters or isolated cells. The characteristic blunt-ended and cigar-shaped nuclei containing coarse chromatin and prominent nucleoli were identified in case 2. Nuclear atypia, prominent nucleoli and high cellularity permit diagnosis of malignancy, although the atypia is generally less pronounced than in the histology. The cytological diagnosis of leiomyosarcoma may be auxiliary in the diagnosis of recurrence or metastasis in the patients with alleged leiomyosarcoma.

Secretory carcinoma is a very rare tumor of the breast, having characteristic histologic findings. A cytologic study of a secretory carcinoma is presented. The smears were abundant in tumor cells which were arranged in loosely adherent or large tight clusters in clear background. The individual cells were round or oval, monomorphic, and had abundant eosinophilic cytoplasm. The cytoplasm showed distinct borders and single or fine vacuolization. The nuclei were peripherally located, oval, and vesicular with small prominent nucleoli. As in histology, the cytologic features were so characteristic that a diagnosis of secretory carcinoma could be made by ctyologic study only.

35세 및 22세 여자의 경부에 생긴 종괴의 세침흡인 세포학적 검사에서 악성이 의심되는 병변 및 악성 병변으로 오진되었던 모기질 세포종 2예의 세포학적 소견을 기술한다. 핵 세포질의 비율이 높고 뚜렷한 핵소체를 보이는 기저양 세포, 농염성 핵을 가진 각화된 편평상피세포, 이물형 거대세포 및 괴사성 배경을 보였고, 후속하여 보았을 때 이러한 소견은 모기질 세포종의 특이적인 소견으로서 악성 종양으로 보기에는 염색질의 분포가 균질하고 핵들의 다형성이 없는 점이 악성 종양과는 구별되는 소견이었고, 모기질 세포종은 경부 종괴 및 여하한 부위의 피하 종괴의 세침 흡인에서 상기의 소견을 보일 때 감별 진단의 하나로서 고려해야한 양성 병변이다. We describe cytologic findings of two cases of pilomatrixoma which had been cytologically misdiagnosed as suspicious malignant and malignant lesions in 35 year-old and 22 year-old females who presented a palpable neck mass. The cytologic smears showed many basaloid cells with a high nuclear-cytoplasmic ratio, nuclear hyperchromatism and prominent nucleoli, keratinized squamous cells with pyknotic nuclei, foreign body giant cells, and chronic inflammatory cells in necrotic back-ground. Retrospective view of this aspiration smear revealed that these findings were characteristic features of pilomatrixoma, and the evenly distributed chromatin pattern as well as the lack of nuclear pleomorphism were considered to be the differential points from malignant neoplasm. Pilomatrixoma is a benign neoplasm which should be included in differential diagnosis if the fine needle aspiration cytologic smear of a neck mass or subcutaneous mass of any site showed these features.

Two cases of giant cell tumor of bone diagnosed by fine needle aspiration cytology are described. Case 1 was a 28-year-old male who had pain sense for one year at the right distal thigh. His radiologic finding revealed a destructive cortical lesion with soft tissue extension at medial side of epiphysis of the distal femur. Case 2 was a 21-year-old female complaining pain at left distal forearm for eight months and showed a well-demarcated expansile osteolytic lesion with multiseptation, and cortical destruction at epiphysis and metaphysis of the left distal radius on the X-ray. Fine needle aspiration of each lesion was performed. The aspirate of the case 1 revealed moderate cellularity, which was composed of scattered giant cells of osteoclastic type and small round to oval monotonous stromal cells in large areas. Giant cells were evenly distributed in single or small groups and had irregular but abundant cytoplasms with 10 to 20 nuclei in the center. The nuclei showed ovoid shape, fine granular chromatin, and a small but conspicuous nucleolus. Stromal cells were dispersed in isolated pattern or sometimes aggregated in clusters and showed the same nuclei as those of giant cells and scanty cytoplasms. Comparing to case 1, case 2 had a more translucent abundant cytoplasm in the giant cells and more spindled stromal cells. All two cases revealed neither nuclear atypism nor increased abnormal mitoses In both giant and stromal cells, suggesting no evidence of malignancy. Thereafter the lesions were treated with excision and curettage, and histologically confirmed as giant cell tumors of the bone.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells haying predominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei. The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchioloalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

A total of 362 bile samples from 104 patients with evidence of biliary tract obstruction were submitted for diagnostic cytology from January, 1989 to April, 1991. The patients were classified based on the obstructive cause, and the cytologic results were reviewed. 298 of the specimens were from patients with intrabiliary malignant structure, and 17 were from patients with extrabiliary malignant compression or benign biliary obstruction. Bile cytology was positive for carcinoma in 42 samples from patients with intrabiliary malignant stricture, and the diagnostic sensitivity was 14%. There were no false positive cases. We concluded that the cause of low sensitivity was degenerative change of cell due to prolonged sampling time. What is noteworthy was the high prevalence of Clonorchis sinensis eggs, being detected in 25 patients with intrabiliary malignancy, supporting the association between clonorchiasis and biliary tree malignancy.

Cytologic findings of pleural effusion in three cases of rhabdomyosarcoma are reported. Case 1 was a pleomorphic rhabdomyosarcoma which had devoped at the chest wall of an elderly male patient and caused pleural effusion. The cytologic features were consistent with pleomorphic rhabdomyosarcoma, that was, showing loose clusters, cellular pleomorphism, and abundant finely vesicular cytoplasm. Cases 2 and 3 were embryonal rhabdomyosarcomas in young adults. Primary site was the oral cavity in case 1, but unknown in case 2 and case 3. The effusion cytology was similar in these cases. Clustered or isolated small round cells with hyperchromatic nuclei and scanty cytoplasm were smeared. The cohesiveness of tumor cells was weak and the cells did not show linear arrangement or nuclear melding. Effusion cytology in a sarcoma patient would be diagnostic when the primary site and the type of sarcoma were already known. 저자들은 비교적 접할 기회가 흔치 않은 횡문근육종의 체액 세포학 3예를 경험하였기에 그 임상 소견과 함께 세포학적 소견을 간결히 기술하였다. 제 1예는 흉벽에 다형 횡문근육종이 있는 환자의 늑막 삼출액 소견으로서, 세포들은 느슨한 군집을 형성하거나 개별적으로 흩어져서 도말되었고 핵은 다형성이 심하였으며 다핵을 가지는 세포도 관찰되었고 과염색상을 보였다. 횡문근육종의 특이 소견인 가로무늬는 관찰되지 않았고 세포질은 미세 공포형이었다. 나머지 2예는 구강 원발성 및 원발 병소를 알수 없는 배형 횡문근육종으로서 이들의 늑막 삼출세포학적 소견은 서로 유사하였다. 군집을 형성하거나 개별적으로 흩어진 세포들은 작고 둥근 세포들로서 이들은 미미한 세포질과 과염색상의 핵을 가지고 있었으며 소 세포 암종에서 관찰되는 염주형 배열 또는 주물 현상은 인정되지 않았다. 육종의 체액 세포학은 원발 병소및 아형이 알려진 경우에 진단적이라고 여겨진다.

저자들은 접할 기회가 흔치 않은 갑상선의 저분화암종인 일명 "도암종"의 세침흡인 세포검사 1예를 경험하고 조직학적으로 확인하였기에 문헌검색과 함께 보고하는 바이다. 흡인 도말된 세포들은 비교적 깨끗한 도말배경에 중등도 이상의 높은 세포밀도를 보였으며, 세포들은 개개로 흩어지는 양상과 판상의 군집을 이루는 양상이 어우러져 관찰되었다. 때로 세포들이 소포배열을 이루는 곳도 관찰되었다. 대부분의 종양세포들은 비교적 비슷한 크기와 모양을 나타내었으나 일부의 세포들은 현저한 다형성을 보였다. 일부의 세포에서 핵에 주름을 보였으나 소수에 불과하여 이는 어떤 갑상선병변에서나 관찰할 수 있는 비특이적 변화로 간주되었다. 세포의 겹침이 별로 없이 높은 세포밀도를 보이는 점, 세포가 개개로 흩어지는 양상과 소수 다형성이 현저한 세포의 혼재 등은 본 종양을 진단하는데 도움이 되는 소견으로 생각되며, 이러한 소견을 염두에 둠으로써 수술전 진단에 도움을 줄 수 있으리라 생각된다. A case of poorly differentiated "insular" carcinoma of the thyroid is presented and discussed with references to the literature. Un fine needle aspiration cytology of our case, the aspirates were highly cellular with tumor cells appearing as dispersed isolated cells as well as in dense clusters and syncytial formations. Occasional microfollicles containing colloid were evident. Most of nuclei were fairly uniform with considerable variability and a few showed definite atypical features. Nuclear grooving was additional features. Necrotic debris was not seen. Our cytologic findings were correlated well with histology, confirming typical insular pattern of tumor cells with the presence of occasional pleomorphic cells and papillary carcinoma-like features. With much attention to cytological features of insular carcinoma, it would be possible to diagnose a preoperative suggestive diagnosis, even though not definitive.

A case of multiple myeloma with massive pleural effusion is reported. A 53 year-old previous known multiple myeloma patient vistited our hospital complaining of cough with sputum. Radiologic study revealed multiple osteolytic bony lesions and left side pleural effusion. The effusion were bloody exudates containing numerous atypical plasma cells. The tumor cells showed pleomorphism, eccentric nuclei, prominent nucleoli, perinuclear halo, multincleation, and chromatin patterns of occasional cart-wheel appearance. The cytological examination of pleural fluid established the malignant nature of the effusion with multiple myeloma.
