  • The columnar cell variant of papillary carcinoma is a rare tumor of the thyroid, associated with aggressive behavior, early metastasis, and a rapidly fatal course. We present the fine needle aspiration cytologic(FNAC) findings of columnar ceil variant of papillary carcinoma with cytohistologic correlation. In the smears, the tumor fragments showed mainly papillary pattern and a few scattered individual cells were present around the papillary fragments. The tumor cells were columnar or cuboidal and exhibited pseudostratification of the nuclei. The nuclei were oval to elongated with finely stippled chromatin and inconspicous nucleoli. Neither nuclear grooves nor intracytoplasmic inclusion was found. The FNAC diagnosis was consistent with papillary carcinoma. Total thyroidectomy was done and the histologic finding of the mass showed a predominantly papillary and focal solid proliferation of columar cells with marked nuclear pseudostratification. The unique histopathologic features and highly aggressive nature of columnar ceil variant of papillary carcinoma require that this variant should be differeniated from common papillary carcinoma of the thyroid.

  • Mutation of the P53 tumor suppressor gene playa major role in the development of many carcinomas, namely in the colon, breast and bladder, whereas the role played by such mutations in thyroid carcinogenesis remains controversial. Vascular endothelial growth factor (VEGF) induces proliferation of endothelial cells, stimulates angiogenesis, and increases vascular permeability. Increased VEGF expression has been associated with poor clinical outcomes in many malignancies E-cadherin, a calcium-dependent transmembrane glycoprotein, is an adhesion molecule Expression of p53, VEGF and E-cadherin was assessed immunohistochemically in 19 tall columnar variant of papillary carcinoma, 24 common papillary carcinoma and 7 follicular carcinoma. The aim of this study was to evaluate the expression of P53,VEGF and E-cadherin as a potential maker for the prognosis of thyroid carcinomas. The results are as follows: 1) There were no significance in any clinical parameters examined among tall columnar variant of papillary carcinoma, common papillary carcinoma and follicular carcinoma. 2) The expression of P53 demonstrated low in tall columnar variant of papillary carcinoma, common papillary carcinoma and follicular carcinoma, but a significantly high in regional lymph node metastasis. 3) The expression of VEGF demonstrated a significantly high in regional lymph node metastasis than those without metastasis in papillary thyroid carcinoma. 4) The expression of E-cadherin demonstrated less often among papillary carcinomas with lymph node metastasis than in those without metastasis in papillary thyroid carcinoma. In conclusion, it is suggested that VEGF and E-cadherin will be useful for the diagnosis of thyroid carcinoma and serves as a biological marker for thyroid carcinoma lymph node metastasis.

  • The thyroid is the organ that has the greatest risk of malignant tumors among the endocrine tumors. The papillary carcinoma occupies 80% of the entire thyroid tumors. Immunohistochemical staining of galectin-3 has usually been used in differentiating papillary carcinoma and follicular carcinoma. The p53 gene of the cell cycle is a tumor suppressor gene acting in on the control points. The cyclin D1 genes in the cell cycle, involved in the implementation of G1 and S phase, plays an important role in the progression of thyroid tumors. This research compares and analyzes correlation between papillary carcinoma, follicular carcinoma, p53, cyclin D1 and galectin-3 gene expression patterns. In a total of 30 cases from papillary carcinoma, 21 cases from p53 (70%), 27 cases in galectin-3 (90%), and 26 cases in cyclin D1 (86.7%) showed positive rate. The galectin-3 staining investigated, showed a significant difference between a papillary carcinoma and a follicular carcinoma. Follicular carcinoma from 15 cases, p53 in 13 cases (86.7%), galectin-3 in 5 cases (33.3%) and cyclin D1 in 12 cases (80%) showed a positive rate. The cyclin D1 in follicular carcinoma and staining between the p53 that had correlation was also investigated. In this study, as the examples of the expression of the 27 cases of galectin-3 (90%) in papillary carcinoma and 5 cases in follicular carcinoma (33.3%) indicate, it was concluded that there is a difference in the expression on both carcinoma. In addition, cyclin D1 and p53 has a positive rate in follicular carcinoma, when cyclin D1 in 12 cases (80%), there was a significant correlation that was investigated. Distinguishing between papillary carcinoma and follicular carcinoma can be identified by the expression of galectin-3. It is considered to get results that are more accurate in follicular carcinoma diagnosis depending on whether the cyclin D1 and p53 is expressed or not.

  • Oxyphilic (Hurthle) cells have abundant eosinophilic granular cytoplasms and occur in both benign and malignant neoplasms of the thyroid gland. Most published studies described mainly oxyphilic tumors of follicular type, and reports on oxyphilic papillary thyroid carcinomas are rare. The oxyphilic variant of papillary carcinoma differs from the classic papillary carcinoma in its more aggressive biological behavior. We report a case of oxyphilic papillary carcinoma exhibiting exclusively oxyphilic cells in a follicular pattern without papillary structures. The pattern of papillary carcinoma was confirmed by fine needle aspiration material and lymph nodal metastasis, both of which revealed typicaled papillary structures with characteristic nuclear features, psammoma bodies, and oxyphilic cytoplasm.

  • Mixed squamous cell carcinoma and papillary carcinoma in the thyroid gland is a very rare malignant tumor characterized by rapidly progressive clinical course and radioresistance. A 63-year-old woman had mixed squamous cell carcinoma and papillary carcinoma in the thyroid gland diagnosed by fine needle aspiration cytology (FNA), and the diagnosis was confirmed by histological examination. She had complained of a fixed, egg-sized mass of the anterior neck with hoarseness for 1 year. The findings of FNA consisted of sheets and clusters of polygonal epithelial cells with hyperchromatic, pleomorphic nuclei and eosinophilic, abundant, laminated cytoplasm. These findings were consistent with squamous cell carcinoma. Also, fool of papillary carcinoma were noted, and the cells exhibited nuclear groovings and intranuclear cytoplasmic inclusions. Total thyroidectomy specimen showed a diffusely infiltrating tumor in the left thyroid which was composed of mixed papillary carcinoma and well-differentiated squamous cell carcinoma. In junction between two components, squamous metaplasia of papillary carcinoma was noted.

  • Simultaneous occurrence of medullary and papillary thyroid carcinomas in the same gland is very rare. In fact. there are only 18 cases of simultaneous occurrence of medullary and papillary thyroid carcinomas in the literature. We report a case of simultaneous medullary and papillary carcinoma of thyroid gland. A 67-year-old woman was diagnosed with medullary carcinoma of right lobe of thyroid gland and papillary carcinoma of left lobe of thyroid gland by fine needle aspiration cytology. Total thyroidectomy, anterior neck dissection, bilateral modified radical neck dissection and tracheotomy was undertaken. The tumor metastasized to regional lymph node and extrathyroidal muscle invasion of left papillary carcinoma was also revealed by pathological report. This report describes a case of thyroid carcinoma that demonstrated both medullary carcinoma and papillary components in the thyroid with lymph node metastasis.

  • Papillary renal cell carcinoma (RCC) is an uncommon subtype of RCC that has distinctive gross, histologic, and cytogenetic features. The cytologic features of FNA are abundant papillary clusters and relatively few single cells. The cells are usually small and contain uniform nuclei; numerous macrophages with foamy cytoplasm are often found in the background. We describe a case of papillary renal cell carcinoma evaluated by fine needle aspiration cytology(FNAC) in a 42 year-old man. The smear showed a few papillary clusters and numerous macrophages with foamy cytoplasm in the background. With adequate cellularity, papillary RCC can be distinguished reliably from non-papillary RCC by FNAC.

  • Solid papillary carcinoma of the breast is a distinctive form of intraductal papillary carcinoma frequently associated with both mucinous carcinoma and infiltrating ductal carcinoma, not otherwise specific. To our knowledge, this case is the first description of the cytologic aspects of solid papillary carcinoma of the breast in the Korean literature. We experienced a case of solid papillary carcinoma of the right breast diagnosed by fine needle aspiration cytology(FNAC) in a 70-year-old female. FNAC from the right breast showed high cellularity consisting of mostly tight clusters of tumor cells and a few scattered tumor cells. The nuclei were monotonously round to oval in shape with inconspicuous nucleoli. The cytoplasm was abundant and finely granular. Scant amount of mucinous material was present on the background. The diagnosis was confirmed histologically and immunohistochemically.

  • Papillary thyroid carcinoma is rarely associated with macroscopic vascular invasion or tumor thrombosis. Especially, superior vena cava syndrome(SVCS) resulted from tumor thrombosis of papillary thyroid carcinoma is extremely rare. We present herein a case of SVCS caused by tumor thrombosis from papillary thyroid carcinoma which was successfully solved by intravascular placement of self-expandable stent in 74-year-old woman.
