  • The mucoepidermoid carcinoma is a rare tumor in the lung for less than 1% of all pulmonary neoplasm. It is mostly presented as a solitary pulmonary nodule at a large bronchial tree on bronchoscope. But more peripheral located tumor that not accessible to the bronchoscope are rarely reported on literature. The cytologic findings of these tumors are discribed as a mixture of squamous cells, mucous cells, and intermediate cells with overlapped cellular clusters. We experienced a case of peripheral mucoepidermoid carcinoma of lung diagnosed by fine needle aspiration cytology. The smear showed many cellular clusters on mucoid background. They consisted of many intermediate cells with occasional mucus-secreting cells, but malignant squamous cells were not present.

  • Eccrine acrospiroma is a rare adnexal tumor of the skin. When the clinical presentation is that of a breast lump, diagnosis can be difficult. Also, most of the cytopathologists are not familial with the cytologic features of this tumor and this is responsible for diagnostic pitfalls. We experienced a case of eccrine acrospiroma of the right breast in a 41-year-old female, misdiagnosed by fine needle aspiration cytology (FNAC). FNAC was characterized by tight clusters or sheets of small round cells, polygonal cells, and spindle cells and tubule like structures within clusters. Myoepithelial cells were not noted in the clusters. The diagnosis of eccrine acrospiroma was confirmed by histology.

  • Carcinsarcoma is an uncommon pulmonary malignancy characterized by carcinmatous parenchyma and sarcomatous stroma. The cytologic, immunohistochemical and ultrastructural features of a case of pulmonary carcinosarcoma suspected by fine needle aspiration cytology is presented. Only bizarre spindle cells arranged in loose groups, in microtissue fragments and in a dissociate fashion were present on the aspiration smears. They were markedly positive for vimentin. The epithelial component was not found, which was probably due to marked paucity of carcinomatous component that was proved by histologic examination of the resected tumor. The diagnosis of pulmonary carcinosarcoma should be conidered whenever poorly differentiated epithelial ceil groups with a malignant mesenchymal component set in a myxoid background are seen in a pulmonary cytology specimen.

  • We report a case of fine needle aspiration cytology of endodermal sinus tumor of the ovary. A 13-year-old girl complained of abdominal mass and pain. The abdominal sonography revealed a well-demarcated huge mass, which was solid and multiseptated. Percutaneous fine needle aspiration was performed from the mass. The smears revealed moderate cellularity, which was arranged in sheets or clumps of pleomorphic malignant cells on mucoid background The valuable characteristic features of tumor cells were papillary configuration, vacuolated cytoplasm and intracellular and extracellular hyaline globules. The diagnosis was confirmed later by histologic study of surgical resection of the specimen.

  • Medullary carcinoma (MC) of the breast is an uncommon histologic form of infiltrating ductal carcinoma and the cytologic features of MC are not well delineated. We recently experienced a case of fine needle aspiration cytology of MC of the breast. The characteristic cytopathologic features were cellular aspirate consisting of large, pleomorphic cells in background of many single to clusters of lymphocytes.

  • The mucoepidermoid carcinoma is a rare tumor in the lung. A case of bronchial mucoepidermoid carcinoma diagnosed by fine needle aspiration cytology is presented. The smear showed many intermediate cells with occasional mucus-secreting cells. Malignant squamous cells were not present. The cellular arrangement of intermediate cells was overlapping and grouped in ball-like fashion. These cytologic features are unique for diagnosis of this tumor.

  • The purpose of this study was to evaluate the prevalence of thyroid nodules and malignant findings of thyroid nodules in 1,954 patients (654 males and 1,300 females) aged 20 years or older who underwent thyroid ultrasound from January 2018 to December 2018. Examination of the thyroid gland was performed, and fine needle aspiration cytology was performed on the thyroid nodule. As a result, 108 (16.5%) out of 654 males and 368 (28.3%) out of 1,300 females showed higher prevalence than males. The prevalence of single nodules and multiple nodules in gender and age groups was significantly higher for women and for ages (male p=.001, female p=.001). There was a significant difference in males in the nodule size (p=.001) and no significant difference in females (p=.069). Fine - needle aspiration cytology of 476 patients with nodules was diagnosed as malignant in 46 patients (9.6%). Based on pathologic results, 383 benign and 93 malignant groups were analyzed. Ultrasonographic findings were as follows single nodule (p=.000), solid(p=.004), hypoechoic (p=.000), ill-defined peripheral boundary (p=.000), and calcification (p=.000), respectively. In the diagnosis of thyroid nodule, primary ultrasonographic findings through morphological classification of the nodules may reduce indiscriminate fine needle aspiration cytology in benign and malignant nodules.

  • Fine needle aspiration cytology has become a frequently used technique for the diagnosis of lesions in the head and neck. Fine needle aspiration cytology of the salivary glands were performed on 66 patients. In 59 patients with satisfactory samples, cytologic diagnoses were as follows; there were 47 benign lesions, including pleomorphic adenoma(20), Warthin's tumor(3), benign cystic lesion(4), Inflammatory lesion(4), lymphoid lesion(3), myoepithelioma(1), unspecified benign neoplasm (5), and unclassified benign lesion(7). There were 6 cases of undetermined malignancy and 6 malignant lesions including mucoepidermoid carcinoma(3), adenoid cystic carcinoma(1), carcinoma ex pleomorphic adenoma(1), and metastatic carcinoma(1) in cytologic diagnosis. In 25 patients, the cytologic diagnosis was correlated with histologic findings. The sensitivity of the benign lesion was 96% and the specificity was 82%. There was no false-positive diagnosis. The sensitivity and the specificity of pleomorphic adenoma were 75% and 95%, respectively. Some of Warthin's tumors were confused with benign cystic lesion due to frequent cystic change of the tumor. The sensitivity and specificity of the malignant lesions were 56% and 88%, respectively. There were three false negative diagnoses. Two mucoepidermoid carcinomas were correctly diagnosed by cytology. Two of three adenoid cystic carcinomas were misdiagnosed as benign tumors.

  • A total of 48 cases of tuberculous lesion in the lymph nodes (43 cases), lung (3 cases) and soft tissue (2 cases), was subjected to fine needle aspiration cytology (FNAC). The age of the patients ranged from 19 to 77 year-old (average 33.6 years in age) and the male to female ratio was 1 : 4. Thirty-four cases (70.8%) demonstrated distinct granulomatous reaction with or without caseation necrosis, nine cases (18.8%) showed no granulomas, but large amount of necrotic debris with numerous polymorphonuclear cells and histiocytes, and five cases (10.4%) revealed acellular material only. The overall AFB positivity in smears was 62.5%. In areas associated with granulomatous reaction and necrosis, AFB positivity was 55.8%, while it was 80.0% in cases with acellular necrotic material. There were 2 cases of parasitic infestation which could not be easily differentiated from tuberculosis based on aspiration smears only.

  • Amyloid golfer is a rare disease entity that is defined as a symptomatic mass or clinically detectable thyroid enlargement because of amyloid deposition. We present a case of amyloid golfer diagnosed in the fine needle aspiration cytology(FNAC) in a 73-year-old Korean woman presented with nephrotic syndrome and thyroid enlargement. The thyroid function was in normal range. Thyroid scan showed a nodule, $4{\time}2cm$ in the right lobe with underlying diffuse golfer. Aspirates revealed benign looking follicular cells and scattered eosinophilic material. The sections of the cell block showed nodular deposit of eosinophilic hyalinized material in the interfollicular area. It showed apple-green birefringence under polarization with Congo red stain. The renal biopsy also exhibited deposition of eosinophilic materials in the glomeruli and interstitial vascular wall, which were confirmed as amyloidosis. This material was morphologically distinct from the colloid.
