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.

Fine needle aspiration cytology is considered as a useful diagnostic procedure in management of patients with breast lesions. This study was undertaken to evaluate the scoring system of Masood in the interpretation of breast aspirates, to establish the most useful cytologic criteria for the diagnosis of breast lesions, and to subclassify the benign breast diseases. To assess the feasibility of a cytologic grading system, 57 cases of benign breast disease, 61 cases of malignant breast disease were studied, respectively. The aspirates were evaluated for the cellular arrangement, the degree of cellular pleomorphism and anisonucleosis, and the presence of myoepithelial cells and nuceoli. Values ranging from 1 to 4 were assigned to each criterion and the sum of the individual values was made for each case. The presence of stroma, apocrine metaplasia, foamy histiocytes and inflammatory cells, background of the smear, and cellularity were also evaluated. Cut-off value of the scoring system of Masood between benign and malignant lesion was 15. Among the cytologic criteria, cellular arrangement, presence of myoepithelial cells, nucleoli, and stroma, status of chromatin pattern, and background of smear were useful criteria in the differentiation between benign and malignant lesions. Application of the scoring system of Masood does not always make the accurate diagnosis and the subclassification of benign breast disease.

Well differentiated fetal adenocarcinoma of the lung Is a subtype of pulmonary blastoma. In this report, CT-guided fine needle aspiration smears were performed at the right upper lobe of the lung in a 45 year-old male patient who had the smoking history of one pack per day for 25 years. The smears disclosed round, papillary, and tubular patterns of cell clusters. The individual cells had relatively uniform, small to medium sized nuclei without nucleoli, and showed vesicular or eosinophilic cytoplasm with Indistinct cell border. The morules were seen in the central area of papillary clusters. They were composed of two cell types, outer single layered cuboidal cellular lining and central three-dimensional cluster of cells simulating fetal lung. These cytologic features need to be differentiated from usual pulmonary adenocarcinoma, carcinoid, and pulmonary blastoma. On histologic findings, the tumor arised in the bronchial epithelium. And the tumor cells had abundant intracytoplasmic glycogen with neuroendocrine feature on histochemical study. In addition, the multiplicity of this tumor is the unique point comparable to the previous reports.

Inflammatory myofibroblastic tumor, histologically characterized by the presence of bland-locking spindle cells and infiltration of chronic inflammatory cells, is extremely rare in the gastric wall. We report a case of gastric inflammatory myofibroblastic tumor In a 27-month-old boy. The fine needle aspiration biopsy from the mass showed loose clusters or scattered spindle cells and inflammatory cells, predominantly of lymphocytes and plasma cells. The spindle cells resembled fibroblasts or myofibroblasts. Differential diagnosis from benign and malignant diseases involving abdominal cavity was discussed.

Urothelial carcinoma accounts for 90% of all the cases of bladder cancer. Although many cases can be easily managed by local excision, urothelial carcinoma rather frequently recurs, tends to progress to muscle invasion, and requires regular follow-ups. Urine cytology is a main approach for the follow-up of bladder tumors. It is noninvasive, but it has low sensitivity of around 50% with using the conventional cytospin preparation. Liquid-based cytology (LBC) has been developed as a replacement for the conventional technique. We compared the cytomorphometric parameters of $ThinPrep^{(R)}$ and cytospin preparation urine cytology to see whether there are definite differences between the two methods and which technique allows malignant cells to be more effectively discriminated from benign cells. The nuclear-to-cytoplasmic ratio value, as measured by digital image analysis, was efficient for differentiating malignant and benign urothelial cells, and this was irrespective of the preparation method and the tumor grade. Neither the $ThinPrep^{(R)}$ nor the conventional preparation cytology was definitely superior for distinguishing malignant cells from benign cells by cytomorphometric analysis of the adequately preserved cells. However, the $ThinPrep^{(R)}$ preparation showed significant advantages when considering the better preservation and cellularity with a clear background.

Mucoepidermoid carcinoma is the most common malignant neoplasm of the salivary gland, compring between 30 and 40%. Fine needle apsiration cytology was performed in five patients with mucoepidermoid carcinoma. The patients consisted of three males aged of 42, 48, and 60 years, and two females aged 36, and 56 years. The primary tumor sites were the parotid gland in four patients and the submandibular gland in the rest one. The histologic grades were low in one patient, intermediate in two patients and high in other two. In our experience, the common cytologic findings of low grade subtype were predominent mucous cells with some intermediate cells in an abundant mucinous background. The cytologic findings of intermediate grade subtype were predominant clusters of intermediate cells with or without mucous cells in an abundant mucinous background. And the cytologic findings of high grade subtype were predominant clusters of epidermoid cells with intermediate cells in a bloody background. Cytologic pleomorphism and atypia were more severe in high grade than low and intermediate grade, and nucleoli were more frequently noted in epidermoid cells. In low grade, it is very difficult to decide the benignancy or malignancy of the tumor. In fact, the presence of mucous cells in a mucinous background should rule out any other type of well differentiated carcinoma.
