A case of primary non-clear-cell adenocarcinoma of the vagina is reported occurring in a 65-year-old woman without exposure to diethylstilbestrol (DES) in utero. The adenocarcinoma did not appear to be associated with vaginal adenosis. It lacked clear cell component and interestingly composed of columnar epithelial cells of endocervical-type. Cytologically round to oval nuclei revealed one or more small nucleoli and fine granular chromatin pattern. Cytoplasm was plump, faintly basophilic and homogeneously stained. Histologically well differentiated columnar epithelial cells were arranged on trabecular pattern mainly, and also occasional glandular lumina and small solid sheets were found. Mitoses were hardly found.

Multinucleated giant cells of osteoclast-like appearance can be seen in a type of anaplastic carcinoma of thyroid and only a few case reports for fine needle aspiration cytologic findings are found in the literatures. Recently, we experienced a case of anaplastic carcinoma of thyroid with many osteoclast-like giant cells in a 72-year-old woman. The cytologic features and immunohistochemical results are described with special emphasis on differential diagnosis.

An unusual case of papillary carcinoma of the thyroid revealing numerous multinucleated giant cells in the aspiration biopsy cytology is reported. Papillary carcinoma is the most common malignant neoplasm of the thyroid and is frequently diagnosed by aspiration biopsy cytology. Recently, we experienced a case of papillary carcinoma with many multinucleated giant cells in a 55-year-old woman. The cytologic features are described.

Retinoids have been shown to be effective in suppressing tumor development in chemical carcinogens such as N-nitroso-N-methylurea (NMU) and N-nitroso-N-ethylurea (NEU) induced mammary tumors in various animals. However, retinoids-mediated chemopreventive process, linked to transcription factor NF-kappaB activation on chemoprevention has yet to be studied. (omitted)

Intracystic papillary carcinoma(IPC) of the breast is a distinctive and very rare variant of intrductal carcinoma. The cytologic features of IPC have been rarely reported, and there are difficulties in distinguishing between benign and malignant papillary breast lesions. Herein we report a IPC of the breast in a 80 year-old female. Fine needle aspiration cytology revealed monotonous cuboidal epithelial cells in small clusters and individually scattered on bloody background. The tumor cells did not show overt cytologic atypia. With the histologic features of this case and review of the literature, the cytologic differential points are discussed.

A 16-year-old female Poodle with multiple mammary masses was referred to the Veterinary Medical Teaching Hospital of Seoul National University. Radiographic finding indicated a round mass of soft tissue density at the ventral portion of the 4th-7th sternum, which was 7 cm in diameter and presented multiple mineralization within the mass. Cytologically, aspirate of the mammary mass was moderately cellular and revealed well-differentiated osteoblasts with moderately basophilic cytoplasm, various sized and eccentrically placed nuclei and distinct nucleoli. Osteoblasts interspersed with osteoid-suspected pink-staining intercellular matrix. Some cells displayed malignant features such as macronuclei, macronucleoli, binucleation, abnormal mitotic figures, anisocytosis and anisokaryosis. On which the mass was diagnosed as osteosarcoma. Histopathologic examinations of the mass were compatible with a diagnosis of osteosarcoma. The patient was treated with surgery alone. The patient died 45 days later from surgery.

Background: The prevalence of esophageal cancer (EC) with second primary cancers (SPC) is increasing worldwide. This study was aimed to understand the clinical features of EC patients with SPC in the Taiwanese population. Materials and Methods: Clinical and laboratory data for 180 EC patients with or without SPC were collected between January 2009 and December 2013. Information on treatment approaches, location of SPCs and ABO blood type were also collected and stratified. Results: The most common SPC in EC patients was hypopharyngeal cancer, followed by laryngeal cancer and hepatocellular carcinoma in our study. Malignancies of colon, prostate and lung were also found. There was a significant higher portion of blood type A in the EC patients with SPC compared with those without (42.4% vs 19.5%, P=0.006). Conclusions: The frequency and SPC site distribution and blood type A should be considered in clinical evaluation of EC patients with a high risk of developing SPC in the Taiwanese population.

A case of retroperitoneal paraganglioma is presented with fine needle aspiration cytologic features. A 57-year-old woman complained of abdominal discomfort and left flank pain for 2 years. The abdominal CT scan revealed an ovoid mass left to the abdominal aorta. Percutaneous fine needle aspiration was performed from the mass. The smear revealed cellular sheets or groups on hemorrhagic background. The tumor cells were ovoid, round to spindle shaped with mild to moderate cellular pleomorphism. The nuclei were round to ovoid and had evenly dispersed chromatin and small nucleoli. The cytoplasm was amphophilic, finely granular and poorly defined. Cells having large or spindle nuclei were quite frequently observed, however, mitosis was not present The cytologic findings suggested paraganglioma, but the frequent spindle cell pattern and the pleomorphism made it difficult to exclude other endocrine tumors and sarcomas. The clinical, histological and ultrastructural findings as well as cytologic findings contributed to confirmatory diagnosis.

Background: Quantitation of urine protein is important in dogs with chronic kidney disease. Various analyzers are used to measure urine protein-to-creatinine ratios (UPCR). Objectives: This study aimed to compare the UPCR obtained by three types of analyzers (automated wet chemistry analyzer, in-house dry chemistry analyzer, and dipstick reading device) and investigate whether the differences could affect clinical decision process. Methods: Urine samples were collected from 115 dogs. UPCR values were obtained using three analyzers. Bland-Altman and Passing Bablok tests were used to analyze agreement between the UPCR values. Urine samples were classified as normal or proteinuria based on the UPCR values obtained by each analyzer and concordance in the classification evaluated with Cohen's kappa coefficient. Results: Passing and Bablok regression showed that there were proportional as well as constant difference between UPCR values obtained by a dipstick reading device and those obtained by the other analyzers. The concordance in the classification of proteinuria was very high (κ = 0.82) between the automated wet chemistry analyzer and in-house dry chemistry analyzer, while the dipstick reading device showed moderate concordance with the automated wet chemistry analyzer (κ = 0.52) and in-house dry chemistry analyzer (κ = 0.53). Conclusions: Although the urine dipstick test is simple and a widely used point-of-care test, our results indicate that UPCR values obtained by the dipstick test are not appropriate for clinical use. Inter-instrumental variability may affect clinical decision process based on UPCR values and should be emphasized in veterinary practice.
