  • Objective: This article concerns evaluation of the sensitivity, specificity and accuracy of FNAB for pre-surgical diagnosis of benign and malignant lesions of major and minor salivary glands of patients treated in the Department of Head and Neck Surgery of Erasto Gartner Hospital. Methods: This retrospective study analyzed medical records from January 2006 to December 2011 from patients with salivary gland lesions who underwent preoperative FNAB and, after surgical excision of the lesion, histopathological examination. Results: The study had a cohort of 130 cases, but 34 cases (26.2%) were considered unsatisfactory regarding cytology analyses. Based on the data, sensitivity was 66.7% (6/9), specificity was 81.6% (71/87), accuracy was 80.2% (77/96), the positive predictive value was 66,7% (6/9) and the negative predictive value was 81.6% (71/87). Conclusion: Despite the high rate of inadequate samples obtained in the FNAB in this study the technique offers high specificity, accuracy and acceptable sensitivity.

  • A 32-year-old female was admitted for evaluation of known mass on right suprahilar area. Chest PA showed $4{\times}3cm$ round and homogenous mass on suprahilar area. No abnormal findings were found in PFT, cytology, bacterial study, and fine needle aspiration biopsy(FNAB). On chest computed tomography, solitary mass was on right suprahilar area and no evidence of intrapulmonary metastasis or lymphnode metastasis was seen. Right upper lobectomy of lung was performed and Castleman's disease of hyaline vascular type was diagnosed based on the histologic findings of multiple and large lymphoid follicles with prominent vascular proliferation and hyalization in the central portion.

  • Infection of the uterine cervix by human papilloma viruses (HPV) may be associated with cervical pre-cancer and invasive cervical carcinoma if left untreated. With advance in molecular techniques, it has become easier to detect the resence of HPV DNA long before the appearance of any lesion. This study concerned cervical scrape samples of 310 married non-pregnant women attending a gynecology outpatient department for both Pap and PCR testing to detect HPV DNA. Nested PCR using primers for L1 consensus gene with My9/My11 and GP6+/GP5+followed by multiplex PCR were carried out to detect HPV 16 and HPV18. Result: HPV prevalence was 11.9% out of which 3.67% cases of negative for intra-epithelial lesion or malignancy (NILM) and in 71.1% (27/38) of atypical cervical smears were HPV positive. There was increasing trend of high-risk-HPV positivity (HR HPV 16 and 18), from 20% in benign cytology (NILM) to 42.9 % in LSIL, 71.41% in HSIL and 100% in SCC. There was highly significant association of HPV infection with cervical lesion ($x^2=144.0$, p<0.01) and also with type specific HPV prevalence ($x^2=7.761^*$, p<0.05).

  • The recently proposed Bethesda system for cervical/vaginal cytology has made a standardization related to "atypia". In cellular change due to inflammation or repair, the word "benign cellular change" has been suggested as a substitute for atypia. Terminology related to atypia cells may become standardized, but the cytologic criteria has not been well defined yet Among 8113 cases screened, we evaluated 182 cases as atypia squamous cells undetermined significance (ASCUS) by the Bethesda system (TBS): 52 cases of ASCUS were cytologically diagnosed and 33 cases were histologically verified. ASCUS was diagnosed based on nuclear enlargement and nonclassical signs of condyloma. The results are as follows; Six cases (16.6%) turned out to have benign cellular change. Twenty five cases (69.1%) demonstrated squamous intraepthelial lesion, condyloma was 2 cases (6.0%) and mild dysplasia was not revealed. Moderate and severe dysplasia were 1 case (3.0%) and 16 cases (48.4%), squamous cell carcinoma and adenocarcinoma were 4 (12.1%) and 1 cases (3.0%), respectively. Our data suggested that patients with ASCUS are highly recommended to be examined colposcopic biosy to cornfim.

  • A 3-years-old female Pointer was evaluated for anorexia, dyspnea and exercise intolerance for 10 days. Auscultation revealed muffling of heart sound. There were leukocytosis, anemia, hypoalbuminaemia and hyperglobulinaemia on the blood profiles. Radiography showed severe pleural effusion. Thorax ultrasonographs described traped pleural effusion, pericardial effusion and collapsed right lung lobe(s). On CT images, thoracic neoplasia and lung torsion were ruled-out. Thoracocentesis with thoracoscopy and bacterial culture revealed pyothorax and pleuritis. The diagnosis of pyothorax in dogs and cats is based on clinical signs, radiography, thoracocentesis and cytology and culture of the exudate. In this case, various diagnostic medical imaging techniques (radiography, ultrasonography, CT and thoracoscopy) were used for diagnosis of pyothorax.

  • A six year old female Shih Tzu was euthanized after having about 2 months history of weakness and convulsion with hypoglycemia. On ultrasonography, several masses in variable sizes were noted in the liver and fine needle aspiration cytology revealed probable neoplasm of pancreatic origin. On necropsy, numerous round firm tan nodules with central depression were noted in the liver and heart. Mesenteric lymph node was enlarged and fused with presumable pancreatic tissue. Based on the histopathology and immunohistochemistry, the tumor was confirmed as malignant metastatic insulinoma.

  • An 8-year-old, female Pointer dog was presented with weight loss, hematochezia, and dyschezia. For the diagnosis, physical examination, complete blood counts, serum chemistry, radiography, ultrasonography, computed tomography, colonoscopy, cytology and histopathological examination were performed. The complete blood counts and serum biochemistry results were within the reference range. Ultrasonographic findings were presented with the thickened wall of the colon and rectum. Colonoscopy revealed irregular and ulcerated mucosal surface, mass and luminal narrowing of colorectal lesions. There were thickened wall and contrast enhancement of the lesion in colorectal region on the computed tomography. The cytologic examination suggested the adenocarcinoma. Postmortem histopathologic examination revealed adenocarcinoma. Based on these findings, the dog was diagnosed with annular colorectal adenocarcinoma.

  • The aim of the present study is to demonstrate the usefulness of intraoperative fine needle aspiration (FNA) of pancreatic lesions in 30 patients. A conclusive diagnosis was done in 27 patients and the diagnoses of three patients were deferred. No complications followed the procedure. Based on histologic findings of the resected specimens in 20 cases and of cell blocks in 10 cases, the final diagnoses were adenocarcinoma in 19 cases, chronic pancreatitis in nine cases and tuberculosis in two cases. The sensitivity, specificity and diagnostic accuracy were 95%, 100% and 96% resepectively and there were no false positives. The smear of aspirate was stained with toluidine blue and examined by light microscope. The presence of there-dimensional clusters of disoriented cells and the increased nuclear/cytoplasmic ratio with large prominent nucleoli were the most helpful criteria for a diagnosis of malignancy in the pancreas. The intraoperative FNA of pancreatic lesions was considered as a simple, safe, and highly specific and sensitive tool in differentiating benign from malignant lesions. The intraoperative FNA can be recommended as the first tool of choice of intraoperative diagnostic procedure in lesions of the pancreas.

  • A 5-year-old castrated male domestic shorthair cat was referred for further investigation of pulmonary nodules incidentally detected on thoracic radiographs. Thoracic radiographs identified ill-defined soft tissue opacity nodules with small faint mineral opacity. Thoracic computed tomography (CT) revealed that bronchial dilation and bronchial wall thickening in bilateral cranial and accessory lung lobes. Round to ellipsoid mineralized concretions were found embedded in the intrabronchial soft tissue attenuation material. Based on radiography, CT, and cytology, the patient was tentatively diagnosed as having broncholithiasis with chronic bronchitis. This report described the CT diagnosis of broncholithiasis, which has been rarely reported in a cat.

  • A 6-year-old spayed, female golden retriever dog was presented with a skin mass on the dorsal region of the right carpus. The cytology result of the region revealed characteristics of mast cell tumors (MCTs). Short wave-infrared fluorescence-guided surgery using Indocyanine green (ICG) was performed to determine the surgical margin of the tumor. ICG was injected intravenously 24 hours before the surgery and the patient was hospitalized and carefully monitored. During the surgery, ICG fluorescence-based surgery was performed to identify the tumor and the surgical margin. The tumor was visible, and the skin mass was resected using NIR device for the guidance of the surgical margin of the tumor. Once the resection was complete, the surgical site was again inspected with SWIR fluorescence imaging to identify residual tumor cells. The resected tumor, using ICG navigation, was classified as low-grade cutaneous MCT and the margin was complete on the histopathological result. We report herein a case of resection of a cutaneous MCT in a dog using SWIR fluorescence imaging ICG which can be potentially used for the identification of tumors and evaluation of the surgical margin for complete resection.
