primary de novo intraosseous carcinoma is a rare neoplastic lesion which commonly occurs in the jaws. it is an epithelial odontogenic malignancy arising from odontogenic epithelial residues in the bone rather than from a preexisting epithelial lesion. in the present case report, the clinical, radiological and histological features of primary de novo intraosseous carcinoma are discussed and its ...

PURPOSE To compare the cytological results of ultrasound-guided fine-needle aspiration (US-FNA) cytology of thyroid nodules to sonographic findings and determine whether US findings are helpful in the interpretation of cytological results. MATERIALS AND METHODS Among the thyroid nodules that underwent US-FNA cytology, we included the 819 nodules which had a conclusive diagnosis. Final diagnos...

OBJECTIVE To show the benefits of fine-needle aspiration biopsy (FNAB) in managing thyroid nodules. METHODS As a retrospective study, reports of 888 FNABs of the thyroid performed during a period of 11 years (1996-2007) at Tehran University of Medical Sciences, Sina Hospital and Endocrine Clinic, Tehran, Iran were reviewed. Histological diagnoses were available for 182 cases, and we compared ...

To examine the immunohistochemical alterations associated with the histological dedifferentiation of thyroid carcinomas, we performed staining for HBME-1, high molecular weight cytokeratin (HCK), CK 19, thyroid transcription factor-1 (TTF-1) and E-cadherin (E-CD) on 125 various types of thyroid carcinomas. The HBME-1 staining was strong and diffuse in follicular carcinoma (FC), papillary carcin...
