  • A 2-year-old, 12.5 kg, castrated male, mixed-breed dog was presented with a 1-year history of pruritus and progressive alopecia. On physical examination, no remarkable findings were detected including body condition score (5/9). A dermatological examination of the dog revealed generalized erythema, papules or plaques, especially on the face, auricle, dorsum, and shoulder. A fine-needle aspiration of the dorsum and face lesions revealed various numbers of macrophages with foamy cytoplasm and multinucleated giant cells. A bacterial culture test showed the growth of Staphylococcus pseudintermedius. A complete blood cell count was unremarkable and biochemical abnormalities included hyperglobulinemia (4.8 g/dL, reference interval 2.5-4.5 g/dL), mild hypertriglyceridemia (277 mg/dL, reference interval 10-100 mg/dL) and mild hypercholesterolemia (383 mg/dL, reference interval 110-320 mg/dL). Additional diagnostic tests were performed to identify the underlying cause of hyperlipidemia. Canine pancreatic lipase immunoreactivity (<50 ng/mL, reference interval 0-200 ng/mL) and total T4 (1.4 ㎍/dL, reference interval 1.1-5.6 ㎍/dL) were within the reference intervals. For a definitive diagnosis, skin biopsy specimen was collected from the papular lesions on the dorsum by using a 4 mm biopsy punch. A histopathological examination revealed numerous large macrophages with abundant foamy cytoplasm in the dermis. The foamy macrophages were located diffusely between the collagen fibers. Extracellular amorphous lipid deposits were also presented in the dermal tissue. A definitive diagnosis of cutaneous xanthoma was made based on clinical signs and cytological and histopathological results.

  • Cytological examination is widely used as a diagnostic tool because of the ease of collecting cells from the involved area. However, the diagnostic yield of cytological examination is unsatisfactory; the reasons include sampling error, poorly prepared samples, small numbers of malignant cells, and low grades of cellular atypia. In this study, we focused on the high infectivity of adenovirus towards epithelial cells and applied the luciferase-expressing adenoviral vector to a new cancer cell detection tool. In addition, adenoviral infectivity was enhanced by modifying viral fiber proteins. The sensitivity of the diagnostic tool was tested using the NCI-H1299 lung cancer cell line, and validated in body fluid samples from cancer patients with a variety of etiology. Results showed that the adenovirus efficiently transfected NCI-H1299 with high sensitivity. Only 10 cancer cells were sufficient for detection of luciferase signals. In body fluid samples, the adenovirus confirmed the diagnosis for malignant and benign cancer, but not in non-epithelial cell derived samples. This study provides proof-of-concept for a more reliable and sensitive diagnostic tool for epithelium-derived cancer.

  • Abnormalities of p53 gene are common in lung cancers and are associated with immunologically detectable p53 protein. p53 immunoreactivity is uncommon in normal cells but is frequently seen in neoplasia. Therefore, assessment of p53 expression may assist in the cytological diagnosis of malignancy. The usefulness of p53 immunostaining as a marker of malignancy in the cytological analysis of bronchial brush specimens from the patients with lung cancers was investigated in this study. A total of 71 bronchial brush samples submitted for cytologic diagnosis were immunostained with D07, a monoclonal antibody to recombinant p53 protein. Resultant p53 data were correlated with cytologic diagnosis and clinical information. Of the 17 smears with a benign cytodiagnosis, all were p53 negative. Of the 40 cases with a malignant cytodiagnosis (histologically confirmed), 35 were p53 positive and 5 were negative. Of the 14 cases that were cytologically suspicious but nondiagnostic for malignancy, 11 were p53 positive, 9 of which were subsequently proved to be malignant by histologic examination, and the remaining 2 cases were tuberculosis clinically. Forty four of 51 histologically confirmed lung carcinomas were p53 positive, including 25 of 28 squamous cell carcinomas, 13 of 17 small cell carcinomas, 3 of 3 adenocarcinomas, and 3 of 3 large cell undifferentiated carcinomas. These results suggest that p53 immunostaining could be of value as a marker of malignancy in the cytologic examination of bronchial brush specimens. Furthermore, we have shown the possible clinical utility of p53 immunostaining in cytopathological diagnosis, that is, as a valuable adjunct to morphological assessment in the analysis of cytopathologically suspicious cases.

  • Background: Colposcopy is the gold standard procedure for evaluating cervical cytological abnormalities. Although it is essentially a minimally invasive intervention, referral for colposcopy may cause significant distress on patients. In this study, we aimed to determine if pre-procedural anxiety levels have a significant association with procedure related pain and discomfort in women undergoing colposcopy for evaluation of abnormal cervical cytology. We also assessed the impact of various clinical factors on anxiety, pain and discomfort in these patients. Materials and Methods: This prospective study was performed at the gynecologic oncology department of Zekai Tahir Burak Women's Health Education and Research Hospital in Ankara, Turkey between January and June 2013. After taking informed consent, State-Trait Anxiety Inventory (STAI) form and a 14-item questionnaire were filled for women who were admitted to our outpatient colposcopy unit for evaluation of abnormal cervical cytology. STAI scores were calculated for each participant. Immediately after the procedure, visual analog scale (VAS) scores for procedure-related pain and discomfort were obtained. Associations between STAI and VAS scores were investigated using correlation analyses. The effect of various contributing factors on anxiety, pain and discomfort were evaluated with linear regression analysis. The p values less than 0.05 were considered statistically significant. Results: A total of 222 women met the inclusion criteria within the study period. Mean patient age was $38.5{\pm}9.6$. Median state and trait anxiety scores were 47 and 46, respectively. Median VAS scores for pain and discomfort were 4 for both variables. State anxiety had a significant correlation with procedure related discomfort (p=0.02). Colposcopy related pain VAS scores were significantly affected by state anxiety level, marital status and prior gynecological examination (p<0.05). Colposcopy related discomfort VAS scores were significantly affected by state anxiety level, marital status, prior gynecological examination and educational status. Conclusions: Additional measures should be implemented in women that carry higher risk for experiencing pain and discomfort. Social, cultural and lifestyle issues may also affect women's experiences during colposcopy, therefore further studies are needed to define specific determining factors in various populations.

  • Here, we report a case of pulmonary paragonimiasis that was improved with initial anti-tuberculosis (TB) therapy but confused with reactivated pulmonary TB. A 53-year-old Chinese female presented with a persistent productive cough with foul smelling phlegm and blood streaked sputum. Radiologic findings showed subpleural cavitary consolidation in the right upper lobe (RUL). Bronchoscopic and cytological examination showed no remarkable medical feature. She was diagnosed with smear-negative TB, and her radiologic findings improved after receiving a 6-month anti-TB therapy. The chest CT scans, however, obtained at 4 months after completion of anti-TB therapy showed a newly developed subpleural consolidation in the RUL. She refused pathologic confirmation and was re-treated with anti-TB medication. Nevertheless, her chest CT scans revealed newly developed cavitary nodules at 5 months after re-treatment. She underwent thoracoscopic wedge resection; the pathological examination reported that granuloma caused by Paragonimus westermani. Paragonimiasis should also be considered in patients assessed with smear-negative pulmonary TB.

  • An 8 month old leopard gecko (Eublepharis macularius) with a large nodule was referred to our hospital. During the physical examination, the nodule had an unclear boundary from the top of the left eye to the front of the left ear and prevented the opening of the left eye. A hard, cheese-like, yellow, pus-filled nodule was observed. A cytological examination of a pus swab sample revealed pyogranulomatous inflammation with rod-shaped bacteria. Ofloxacin was chosen as the empirical topical antimicrobial drug for treatment. The swab samples were inoculated in trypticase soy agar with 5% sheep blood and incubated at 37℃ for 24 h. Gram-negative bacteria were identified via Gram staining, and the Kirby-Bauer antimicrobial susceptible disk diffusion test against 24 antibiotics according to protocol M100-Ed32 of CLSI showed that the fluoroquinolone group (ciprofloxacin and enrofloxacin) was susceptible to the isolated bacteria. Molecular identification based on 16S ribosomal RNA gene sequencing confirmed that the isolated bacteria had a 99.85% nucleotide similarity with Serratia surfactantfaciens (GenBank accession no. CP014948). After 1 week, the boundaries of the nodule became clear; thus, the abscess was physically removed by expanding the hole formed above the eye for drainage, and flushing was repeated. After another 1 week, new tissue restoration without scarring was observed. This is a rare case report of the successful management of a subcutaneous abscess and scar-free healing in a lizard.

  • A two-year-old, spayed female, 22.5 kg Pungsan was referred with chronic crusts and erosion on the nose. A referring veterinarian prescribed an anti-inflammatory dose (0.5-1 mg/kg/day) of oral glucocorticoids for 5 months, but skin lesions showed no meaningful improvement. A dermatological evaluation revealed a crust, depigmentation, erosion, and erythematous lesion over the nasal planum with a loss of the normal cobblestone texture. Also, firm and multifocal plaques over the thigh, groin, axilla, and dorsum were detected. A cytology examination on the nose, thigh, groin, axilla, and dorsum revealed moderate neutrophilic inflammation and bacterial infection. Abdominal radiography and ultrasonography revealed subcutaneous calcified materials along the thigh, groin, axilla, and dorsum. Calcinosis cutis was suspected because of the adverse effect of previous prolonged corticosteroid therapy. A histopathology examination of the nose lesion revealed moderate to severe degenerative or apoptotic changes of the basal layer and lymphoplasmacytic interface dermatitis. Facial discoid lupus erythematosus (FDLE) was diagnosed based on the history and the clinical, cytological, and histopathological results. Minocycline (7 mg/kg PO q 12 h) and niacinamide (500 mg/dog PO q 12 h) were prescribed as initial treatment. Glucocorticoids were not administered due to the presence of calcinosis cutis induced by previous corticosteroid treatment. After 6 weeks of treatment, the clinical signs on the nose were mildly improved. At this time, topical 1% pimecrolimus cream (twice daily) was initiated, while minocycline and niacinamide were continued at the same dose. The nasal planum markedly improved after 6 weeks of additional treatment, hence minocycline and niacinamide were prescribed for an additional 2 weeks and stopped, and the patient was continued solely on topical pimecrolimus. The dog's skin lesion has been maintained in clinical remission with topical 1% pimecrolimus twice daily for more than 5 months.

  • Purpose: To study the clinical application value of ultrasound guided thyroid fine needle aspiration biopsy and thinprep cytology testing in diagnosis of thyroid disease. Methods: A total of 78 patients with thyroid nodules were enrolled, 34 males and 44 females, aged 33-64 years old with mean age of 47.6 years. All underwent thyroid module fine needle puncture after surgery to assess cell pathology and histopathological features. Results: Sufficient specimens were obtained from all of 78 patients, the cytological results of 73 cases (93.6 %) being consistent with pathological results. While 20 cases (25.6 %) were malignant tumors, 44 (56.4 %) were benign and 9 (11.5 %) were non-tumor lesions. The sensitivity of benign and malignant thyroid nodule by thyroid fine needle puncture was 90.9 %, specificity was 98.1 % and the positive predictive value was 96.3 %. Conclusions: It is demonstrated that ultrasound-guided thyroid fine needle aspiration biopsy and thinprep cytology testing have diagnostic value in clinical application for thyroid disease,showing good diagnostic coincidence rates with histopathological examination. They can thus be regarded as safe and effective for preoperative diagnosis and providing an appropriate basis for selection of surgery.

  • Although the etiology and pathogenesis of amyotrophic lateral sclerosis(ALS) is unknown, increasing evidence supports a role for autoimmune mechanisms in motor neuron degeneration. The coexistence of immune disease in ALS supports that an altered immune system may contribute to disease pathogenesis. A 55-year-old woman was admitted to our department due to dysarthria and gait disturbance. On physical and neurologic examination, she showed thyroid enlargement, tongue atrophy, muscle weakness, fasciculation, and increased deep tendon reflex. The electrophysiological studies are compatible with motor neuron disease. Cytological findings of thyroid were compatible with Hashimoto's thyroiditis. Thus, we report a case of ALS combined with Hashimoto's thyroiditis. And the simultaneous presentation with ALS and Hashimoto's thyroiditis led us to consider whether this was simply a chance association or not.

  • Pilomatrixoma is a benign skin appendage tumor of hair matrix cell origin. The cytological appearance of this tumor may cause problems when attempting to establish a differential diagnosis with other neoplasms. Herein we report the aspiration cytology findings of two cases of pilomatrixoma. One case was diagnosed as atypical cell clusters initially and the other was diagnosed as pilomatrixoma. On cytologic examination, both cases showed clusters of tightly arranged basaloid cells with an uniform appearance, scanty cytoplasm and round hyperchromatic nuclei. There were histiocytes and multinucleated foreign body giant cells merged with the amorphous opaque orangeophilic materials of "ghost cells". The differential diagnosis with other neoplasms is discussed.
