Material and Methods: This is a retrospective study of fine needle aspiration cytology of subcutaneous swellings over a period of two years from January 2009 to December 2010 in a tertiary care center. A total of 2400 cases of dermal and subcutaneous swellings, for which fine needle aspiration cytology was done with histological follow up, were included in the study. The aspirates were provisio...

Chordomas are low-grade malignant tumors of bone that occur almost exclusively in the axial  skeleton. Chordomas are rare in children and adolescents and comprise <5% of all cases and the  site of development is at the skull base. These tumors are believed to behave more aggressively  than chordomas in adults and may have unusual morphology. We herein present a rare case of chordoma in a 20-yea...

OBJECTIVE: To audit the diagnostic accuracy and value of fine-needle aspiration cytology in the assessment of thyroid nodules over a 5-year period. DESIGN: Retrospective study. SETTING: Private practice, Hong Kong. PATEINTS: The computerised records from cytological and histological examinations of all thyroid specimens submitted from 1993 through 1997 were studied; the 1236 aspirates came from...

BACKGROUND Core needle biopsy is a relatively new technique used to diagnose salivary gland lesions, and its role in comparison with fine needle aspiration cytology needs to be refined. METHODS We compared the results of 228 ultrasound-guided core needle biopsy and 371 fine needle aspiration procedures performed on major salivary gland tumors with their postoperative histological diagnoses. ...

Given that the clinical and radiological examinations of lateral cervical masses are not always sufficient for deciding on appropriate management, the cytological examination of the material obtained by fine-needle aspiration might be an efficient tool in the preoperative investigation of these lesions.In this prospective cross-sectional study we evaluated the efficacy and diagnostic accuracy o...

Thyrolipomas are rare capsulated mass lesions containing fat and thyroid tissue. We herein report the case of a 60-year-old man who had goitre for 10 years, with rapid enlargement of the gland during the last several months before presentation. Sonography, scintigraphy, CT, MR imaging, and sonography-guided fine needle aspiration were performed. Sonography and scintigraphy revealed an unusual m...

Primary extradural meningiomas presenting as scalp swelling is uncommon. Their diagnosis by fine needle aspiration is rare as majority of the lesions are hyperostotic. Primary intraosseus meningiomas involving the skull constitute only about 2% of meningiomas and are often mistaken for other primary or secondary bone tumors. The authors report a case of primary calvarial meningioma involving th...
