Available conventional pathologic diagnostic tools for lung cancer include sputum cytology, lung biopsy using bronchoscopy, and washing and brushing cytology. In addition, fine needle aspiration (FNA) cytology is now available and has become popular. In this study, an attempt was made to compare the relative sensitivity between conventional cytopathologic methods and FNA cytology, to study the clinical characteristics of lung cancer in which the diagnosis was established by FNA cytology, and to study the cellular findings and diagnostic criteria of lung cencers. Cases included in this study were selected from 105 patients who had been diagnosed an lung cancer at Yonsei University Medical Center during the 5-year period from January 1984 to December 1988. These 105 cases were reviewed with respect to medical records and pathologic slides and then the following conclusions were made. The mean age of cases was 58.5 years, and the sex ratio of males to females was 3.5:1. Tumors were mostly solitary in number and were mainly located at the periphery of the lung. The sensitivity of FNA cytology, sputum, and bronchial washing was as follows: FNA cytology was 0.93, sputum, 0.2, and bronchial washing, 0.14. The coincidence rate of cytopathologic diagnosis with histologic diagnosis was as follows: epidermoid carcinoma was 92%, adenocarcinoma 83%, undifferentiated large cell carcinoma 66%, and undifferentiated small cell carcinoma 100%. The false negativity of FNA cytology was 7%, which was mainly due to material insufficiency. For the differential diagnosis of histologic type, some brief criteria could be summarized. Differential diagnostic points of each histologic type were as follows: epidermoid carcinoma showed a large cellular group with keratinized cytoplasms and hyperchromatic and pyknotic nuclei, adenocarcinoma showed a glandular or ball-like arrangement by monotonous round cells, undifferentiated large cell carcinoma was mainly composed of irregular large cells and showed emperipolesis, and undifferentiated small cell carcinoma showed an Indian file appearance with molding by small, round hyperchromatic cells. In conclusion, FNA cytology is a more efficient, definite, and sensitive method for diagnosing lung cancer than other cytopathologic studies, so that careful selection of patients and experienced technique will improve the diagnostic accuracy of FNA cytology in diagnosing lung cancer.

Many articles concerning the accuracy of diagnosis of malignant tumor cells in body fluids have appeared in the literature, but few authors have attempted to describe the characteristics of these cells to determine the site of the primary tumor as they relate to tumors of specific primary sites. This paper presents the results of a retrospective study on malignant body cavity effusions of which the primary site was established on the basis of either biopsy or surgical resection of the primary neoplasm during the period of 6 years beginning from January 1983 to December 1988. The results obtained are summarized as follows: 1) The 143 fluid specimens from 129 patients were composed of 51 cases of pleural, 69 of peritoneal, and 9 of pericardial origin. 2) Adenocarcinoma was the most frequent type of malignant effusions (78.3%). The most common primary site was the lung (50%) in pleural fluid and stomach (55.2%) in ascites. 3) The results of this study show that the primary site of tumor cells can be identified in the body fluid of accurate cytomorphologic criteria are used. Identification of the primary site of an effusion would be improved by the consideration of clinical information

A clinical and histological study of typical sebaceous epithelioma (basal cell epitheioma with sebaceous differentiation) developed secondarily in lesions of nevus sebaceus of Jadassohn is presented. The patient was 42 years old male. The sebaceous epithelioma tends to have about the same clinical characteristics as undifferentiated basal cell epithelioma but it is more often a yellow color. Sebaceous epitheliova may arise from nevus sebaceus and it is preursor of undifferentiated basal ce]1 epithelioma. Histological]y, the preparation showed massive development of sebaceous gland, papillomatous epidermal hyperplasia and maturation of apocrine glands. The tumor cell nests were mostly composed of large sheets of irregularly shaped cells in palisading pattern at the periphery. There were Iarge number of cells with vacuolated cytoplasm resembling sebaceous cell in certain part of the tumor cell masses and several keratin pearls. Diagnosis confirmed by clinical appearance and histological picture. These lesions could be treated sucessfully by wide excision.

Subcutaneous fat necrosis is manifested by erythematous tender nodules on the legs, buttock or trunk and is associated with pancreatic disease including acute and chronic pancreatitis, pancreatic carcinoma, pseudocyst, pancreatic stone and other diseases. Its histologic findings are pathognomonic and reveal foci of subcutaneous fat necrosis with "ghost-like" anucleated cells with thick "shadowy wall" and surrounding inflammatory infiltrate consisting of polymorphonuclear cells, eosinophils, lymphocytes, histiocytes, foam cells and foreign body giant cells. We experienced a case of subcutaneous fat necrosis associated with pancreatic adenocarcinoma manifested by subcutaneous nodules in the buttock and lower extremities and by arthralgia of the left knee in a 67-year-old woman. Therefore, we are reporting to emphasize the importance of the skin findings of the internal disease.

Mucous gland adenoma, one type of bronchial adenoma, is first introduced by Rosenblum and Klein2) in 1935 and very rare. Only twenty-one cases had been reported in english literature. This tumor must be differentiated from other types of bronchial adenoma because of completely benign clinical course. A case of mucous gland adenoma is presented which showed marked secondary calcification.
Adenoma

Pulmonary adenocarcinoma of fetal type is a very uncommon tumor of the lung which simulates an early stage of lung differentiation. This is a primitive appearing epithelial tumor similar to the epithelial component of pulmonary blastoma but lacking the sarcomatous features. Since the report of Kradin et al, 8 more cases have been reported by a variety of name. These tumors are composed of glycogen-rich, non-ciliated tubular epithelial cells forming irregularly shaped tubules or arranged in a papillary pattern. A very remarkable findings of this tumor is the presence of endocrine cells which is confirmed by argyrophilia, immunohistochemistry or electron microscopy. We experienced a case of this tumor which showed hepatocytoid differentiation in addition to the characteristic histologic findings. Immunohistochemical studies performed on a resected tumor tissue showed immunoreactivity for alpha-fetoprotein, neuron-specific enolase and somatostatin, and endocrine type granules were found ultrastructurally. Although this tumor seems to have a relation with pulmonary blastoma in its histology, immunohistochemistry and ontogeny, a distinction between these should be attained because the average survival of the former group is longer as 23 months, while that of the latter is only 4 months.
