It is very rare to diagnose a squamous cell carcinoma when the carcinoma cells are observed in various body fluids. The effusion cytology of squamous cell carcinoma has not been sufficiently studied till now. We examined 10 cases of body fluid cytologic specimen diagnosed as metastatic squamous ceil carcinoma, which were selected among 2,100 body fluid cytology cases collected from 1986 to 1991. The patients had been confirmed to have primary squamous ceil carcinomas. The backgrounds of cellular aspirates were necrotic in most and the cells appeared in clusters or individually. The cell clusters showed round and smooth margins, mimicking adenocarcinoma, but in flat sheets rather than three-dimensional bails. the individual cells were most frequently Graham's 3rd-type cells, found in all cases, which were described as 1.5 times large as the parabasal cells and having small cytoplasmic rims. Other malignant squamous cells were undifferentiated cells, polygonal cells, fiber cells, and tadpole cells with decreasing order of frequency. The recognition of various features of malignant squamous cells would be helpful for the diagnosis of squamous ceil carcinoma found in effusion cytology.

Liver is generally known as an organ which is most commonly involved by the metastic tumors. According to the tendency of using fine needle aspiration in the diagnosis of hepatic tumors, the differentital diagnosis between hepatocellular carcinoma and metastatic carcinoma frequently has been a main issue in the poorly differentitated cases, especially to the pathologists of Korea, an endemic area of hepatocellular carcinoma. Until now the problem has been usually solved by the comparison of cytologic characteristics of their tumor cells but not by background cytologic features which rarely have been studied. We observed the background cytologic features helpful for the differential diagnosis through the analysis of 20 cases who had confirmed primary cancer and were diagnosed as metastatic carcinomas in the liver by fine needle aspiration cytology. Twenty cases included 9 adenocarcinomas, 7 spuamous cell carcinomas, 1 small cell carcinoma, 1 carcinoid, 1 adenoid cystic carcinoma, and 1 renal cell cacinoma. Analysis of background cytologic features revealed that 77% of adenocacinoma cases showed benign mesenchymal components and hepatocytes and spuamous cell carcinoma cases disclosed benign mesenchymal tissue (71%) and necrosis (57%), Remaining cases showed variable combinations of benign mesenchymal component, necrosis, hepatocytes, and bile duct epithelial cells. No case revealed atypical hepatocytic naked nuclei, a useful cytologic finding of hepatocellular carcinoma. In summary, the background cytologic features more commonly observed in metastatic carcinomas than in the hepatocellular carcinoma were benign mesenchymal components, hepatocytes, necrosis, and bile duct epithelium. The endothelial cells and hepatocytic naked nuclei, two relatively specific findings of hepatocellular carcinoma were not observed except for renal ceil carcinoma. Above background cytologic features are thought to be helpful for the differential diagnosis between the hepatocellular carcinoma and various metastatic carcinomas in the poorly differentiated cases.

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.

70세 여자의 늑막에 발생한 점액양 연골육종의 세침흡인세포학적 소견을 기술하였다. 환자는 4개월간의 좌측 흉통과 2개월간의 호흡곤란을 호소하였고 흉부 X-선 및 전산화 단층촬영상 좌측 늑막강에 위치하여 흉벽을 침범하는 커다란 분엽상 저음영성 종괴와 늑막 삼출액이 관찰되었다. 종괴의 세침 흡인 도말은 세포 밀도가 매우 높았고, 세포질이 풍부한 나원형 세포들이 점액성 물질내에 산재되거나 간혹 뭉쳐 있었다. 풍부한 세포질은 불투명한 청색으로 소포를 함유하기도 하였으며 그 경계는 흩어진 세포에서는 비교적 분명했으나 세포집단에서는 불분명하였다. 핵들은 한쪽으로 치우쳐져 둥글거나 난원형을 보였고 염색질은 미세하였으며 다수의 작은 핵소체를 갖고 있었다. 세포들간의 다형성이나 유사분열은 잘 관찰되지 않았다. 이상의 소견은 연공육종의 세포학적 특징과 유사했으나 연골 성분이 관찰되지 않았고 점액성 물질이 매우 풍부하여 확진을 위한 생검이 시행되었고 조직학적으로 점액양 연골육종임이 확인되었다. A 70-year-old female who was diagnosed as myxoid chondrosarcoma by fine needle aspiration of a pleural mass is described. She presented with left chest discomfort of 4 months' duration and aggravating dyspnea and chest pain for 2 months. Chest X-ray and CT scan revealed a large lobulated low density mass invading chest wall at the left pleural cavity and massive pleural fluid. Fine needle aspiration was done under the impression of mesothelioma or metastatic cancer. The aspirates from the mass were very cellular and composed of isolated or clustered forms of large plump cells. Abundant cytoplasm was blulsh opaque and the margin was rounded in the isolated cells, whereas clustered cells show ill-defined ceil borders and aggregating tendency. The nuclei were eccentric, round to ovoid, and had fine chromatin pattern and multiple small nucleoli. Cellular pleomorphism or mitotic figure was not definite. These findings were consistent with cytologic features of chondrosarcoma. Final diagnosis was confirmed as myxoid chondrosarcoma by mediastinoscopic biopsy and the tumor showed strong positivity for S-100 protein.

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.

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis of small and medium-sized muscular arteries that typically involve multiple organs, including peripheral nerve, skin, joint, muscle, gastrointestinal tract, kidney, and heart. In addition to systemic involvement of the classical PAN, localized diseases of the gallbladder, uterus, testis, and skin have been reported. In particular, a limited involvement of the appendix is an unusual manifestation of PAN and usually runs a favorable prognosis when compared with the classical PAN. We described a 13-year-old woman with a limited form of PAN presenting as acute appendicitis without other systemic manifestations. She recovered after exploratory laparotomy and appendectomy without administration of steroid or immunosuppressant.

Splenic tuberculosis is an uncommonly considered diagnosis in clinical practice. This is a case report of splenic tuberculosis in a 13-year-old boy who was seronegative to HIV. He was just well until 7 days prior to this admission when he started to feel epigastric and left subchondral pain. Chest X-ray was not pathological. Abdominal ultrasonography showed slight splenomegaly with multiple hypoechoic nodules and abdominal CT disclosed multiple irregular hypodense lesions in the spleen. Radiological interpretation suggested the possibility of lymphoma or metastatic malignancy. Splenectomy was done and the histopathological findings showed extensive chronic granulomatous inflammation compatible with tuberculosis. Splenic tuberculosis must be included in the differential diagnosis of hypoechoic and hypodense lesions by means of sonography and computed tomography, respectively.

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.

Candida exists in the oral cavity as normal flora, which is cultured in 7% of the population. And the development of candidiasis is usually related to the systemic or local immunosuppressed status such as diabetes, long-term antibiotics, steroid, radiation therapy or chemotherapy. However, isolated laryngeal candidiasis in immunocompetent patients is a rare entity with fewer than 40 cases reported in the world. Symptoms of laryngeal candidiasis are variable such as hoarseness, dysphagia, or odynophagia according to its extent, but it has clinical importance because of its resemblance with laryngeal premalignant or malignant lesions. Diagnosis is made by biopsy under direct laryngoscopy with special staining to identify the hyphae. In this article, we report a case of laryngeal candidiasis presented as leukoplakia localized on vocal fold with literature reviews.

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.
