  • Cystic hypersecretory carcinoma of the breast is a rare variant of ductal carcinoma of breast, first described in 1984 by Rosen and Scott. Histologically, it is characterized by the formation of dilated ducts and cysts containing an eosinophilic secretory product resembling thyroid colloid. Cytologic findings show a few clusters of atypical ductal epithelial cells in amorphous proteinaceous material with clacking artifact. Differential diagnosis include mucinous carcinoma and benign mucocele-like tumor. We present two cases of fine needle aspiration cytology of cystic hypersecretory intraductal carcinoma of the breast with a review of the literature.

  • Pulmonary amyloid deposition generally occurs with concurrent primary systemic amyloidosis. Localized forms of pulmonary amyloidosis are rare and appear most frequently as an incidental finding on chest radiographs. We present a case of nodular pulmonary amyloid tumor suggested by fine needle aspiration cytology(FNAC) and confirmed by histology examination with the polarizing light microscopy. A 41-year-old woman presented with ill-defined nodules. In the middle and lower lobes of both lungs. FNAC of the nodules revealed waxy, acellular amorphous fragments. Thoracotomy for diagnosis may be avoided by FNAC diagnosis of this unusual lesion.

  • Utilization of fine needle aspiration cytology (FNAC) in the diagnosis of odontogenic tumors seems to have little attention. Ameloblastoma is the most common epithelial odontogenic tumor. However, the cytologic findings of ameloblastoma are described recently. We report a case of ameloblastoma diagnosed by FNAC. The aspirated blood-tinged mucoid fluid from maxillary mass showed a few clusters of tumor cells with distinct two-cell population: basaloid cells with palisading arrangement and squamous cells with more abundant and eosinophilic cytoplasm. Nuclear atypism, pleomorphism or mitosis were absent. A few keratinized bodies in the tumor cell clusters and the third component, stellate cells were also characteristic.

  • Lymphoepithelial carcinoma, also known as malignant lymphoepithelial lesion or lymphoepithelioma, is a rare tumor in salivary glands. Lymphoepithelial carcinoma has a characteristic histological findings comprising irregularly-shaped nests of malignant epithelial cells within a lymphocyte-rich stroma, occasionally forming lymphoid follicles. We recently experienced a case of fine needle aspiration cytology (FNAC) of lymphoepithelial carcinoma of parotid gland in a 61-year-old male. The FNAC yielded a hypercellular smear of many irregular clusters of malignant epithelial cells in the background of lymphoid stroma.

  • Tubulolobular carcinoma is a tumor of the breast that shares histoiogic features of both tubular and lobular carcinoma of the breast. The cytologic features of this neoplasm have not been reported in Korea. We described a case of tubulolobular carcinoma diagnosed by fine needle aspiration cytology in a 46-year-old female. The tumor contained several cytologic features of both tubular and lobuar carcinoma, including tubular structures, single filing of cells, intracytoplasmic vacuoles, and low nuclear grade.

  • Fine needle aspiration cytology (FNAC) is an easy convenient non-invasive method in the diagnosis of superficial palpable masses. The cytologic findings by FNAC of reactive and neoplastic lesions in various organs including breast, lymph node, thyroid, salivary gland, etc., have been described, but, those of soft tissue lesions including proliferative fasciitis are relatively rare to find. We recently experienced a case of FNAC of proliferative fasciitis in the left back of a 72-year-old male. The FNAC smears were scant in cellularity and contained large cells with abundant basophilic cytoplasm, one to two nuclei lying at the periphery, and prominent nucleoli that resemble ganglion cells.

  • Alveolar soft part sarcoma (ASPS) is a rare soft tissue sarcoma, which occurs predominantly in adolescents and young adults. The cytological characteristics of this condition have been described only rarely in the literature. Here, we report a case of alveolar soft part sarcoma. A 28-year-old man presented with a mass in his right buttock, which had persisted for three years. The mass was subjected to a fine needle aspiration cytology (FNAC). The smears were cellular. The observed tumor cells were round or polygonal, and exhibited vesicular nuclei with prominent nucleoli and finely granular cytoplasm. Naked nuclei were frequently detected. Tumor cells were arranged singularly, but occasionally in a pseudoalveolar pattern.

  • 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.

  • Fine needle aspiration cytology (FNAC) is a very useful tool in the preoperative diagnosis of lesions of the salivary gland. Surgical therapy of high-grade malignancies (salivary duct carcinoma, mucoepidermoid carcinoma, squamous cellcarcinoma, carcinoma ex pleomorphic adenoma, small cell carcinoma, and sebaceous carcinoma) is different from that of benign lesions or low-grade malignancies. Therefore, the recognition of high-grade malignancies is important in salivary gland FNAC. Although recognition of high-grade malignancies of the salivary gland by FNAC is not difficult, precise classification of these malignancies is often impossible. Additionally, because of its rarity, FNAC of spindle cells and mesenchymal lesions of the salivary glands is a tool that is not familiar to many cytopathologists. The characteristic cytomorphologic features of these lesions are reviewed here with a discussion of specific diagnostic problems.

Fine Needle Aspiration Cytology of Eccrine Acrospiroma of the Breast - Report of a Case Misdiagnosed as Ductal Carcinoma - (유방에 발생한 에크린 선단공한산종의 세침흡인 세포소견 -관암종으로 오인한 1예 보고-)

  • 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.
