BACKGROUND Thyroid nodules with indeterminate fine-needle aspiration biopsy (FNAB) results remain a diagnostic dilemma, because 70 - 85% of these nodules have been found to be benign after thyroid surgery. OBJECTIVES The purpose of this study was to evaluate the usefulness of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in the preoperative diagnosis o...

AIMS/BACKGROUND This study was performed to ascertain the diagnostic accuracy rate of non-invasive tests in patients with presumed uveal melanomas scheduled to be treated with either irradiation or cyclochoroidectomy. METHODS One hundred consecutive patients who had non-invasive tests followed by fine needle aspiration biopsy (FNAB) as prior alternative treatment were analysed retrospectively...

Lymphadenopathy is a common clinical manifestation which requires rapid and accurate diagnosis. Fine Needle Aspiration Biopsy (FNAB) used as an initial direct diagnosis in cases of lymphadenopathy, confirmatory colli lymphadenopathy carried out by histopathological examination. The purpose this study was to determine the value FNAB diagnostic test for against gold standard histopathology Paraff...

Background: Giant cell tumor (GCT) of bone is a relatively common type benign involving the epiphyseal region tubular bones, but GCT rarely occurs at hand (1–4% all GCT). within tends to be more aggressive and recurs rapidly in than other locations. Most authors prefer curettage or resection with reconstruction maintain anatomical functional integrity.Case Report: A 27-year-old man chief compla...

Salivary gland neoplasm (SGN) is one of the largest groups of neoplasms, with over 3 dozen benign and malignant tumors in the 2005 WHO classification and with additional entities recognized during the last decade. Current success of fine needle aspiration biopsy (FNAB) in SGN diagnosis is largely because of its high sensitivity and specificity in: 1) distinguishing neoplastic from non-neoplasti...

BACKGROUND Fine needle aspiration biopsy (FNAB) has been shown to be the diagnostic procedure of choice for superficial lymphadenitis in tuberculosis endemic regions. METHODS We conducted a retrospective laboratory-based study to determine the bacteriological yield of clinically suspected mycobacterial tuberculous lymphadenitis following FNAB in adults, and specifically HIV-positive patients,...

This paper investigates an image classification method performing thyroid carcinoma classification in Fine Needle Aspiration Biopsy cytological images of thyroid nodules under noise conditions and varying staining conditions. The segmentation method combines the image processing techniques thresholding and mathematical morphology. Feature extraction and classification are carried out by discret...

Introduction: In spite of large number of studies regarding relation between thyroid cancer and childhood irradiation, contraversy still exists management of these patients. This study tries to find optimal method of thyroid evaluation in this group. Methods and patients: In a recall program using mass media in Khorasan, all patients with childhood irradiation were invited for thyroid eva...

Solitary fibrous tumor of the pleura (SFTP) is an uncommon entity, generally with an indolent behavior. Nevertheless, some malignant forms have been rarely reported. These, often have an aggressive biological behavior with pathological findings of invasiveness. The preoperative diagnosis and evaluation of the grade of malignancy are extremely challenging. Herein we report a case of a 64-year-ol...

BACKGROUND Malignant mesothelioma is a rare neoplasm that generally develops in the pleural or peritoneal cavity. Distant metastases are common; it rarely metastatizes to the head and neck region. CASE PRESENTATION A 54-year-old white man, a non-smoker, was treated with chemotherapy, surgery and radiation for a malignant pleural mesothelioma. Seven months after the last treatment, he develope...
