Fine needle aspiration biopsy and molecular analysis in differential diagnosis of lymphoproliferative diseases of the orbit and eye adnexa.

Flow cytometry in the diagnosis of lymphoproliferative lesions of the orbit and eye adnexa in fine needle aspiration biopsy.

The goal of the investigation was to evaluate the validity of routine cytology and flow cytometry in the differential diagnosis of lymphoproliferative disorders of the orbit and eye adnexa. The investigations were carried out on materials originating from fine needle aspiration biopsy performed in 14 patients, including 9 females and 5 males aged 31-81 years. Apart from routine cytology, cytome...

Combination of aspiration and non-aspiration fine needle biopsy for cytological diagnosis of thyroid nodules

Background: Good cytological sample is very important for the cytological diagnosis of thyroid nodules. The aim of this study was to evaluate the adequacy of prepared samples by the combination of aspiration and non- aspiration fine needle biopsy. Methods: In this descriptive – analytical study, sampling was done simultaneously for each patient in fine needle aspiration and non-aspiration biops...

Comparison of the Results of Fine Needle Aspiration Biopsy Specimens and Permanent Histopathologic Preparation in Orbital Mass Lesions

Background and Objectives: We aimed at evaluating the efficacy of fine needle aspiration biopsy (FNA) in comparison with histopathology and demonstrating whether cytological study could be a proper diagnostic tool in orbital mass lesions. Materials and Methods: In a cross sectional study during 36 months, patients referred to our ophthalmologic center affiliated to Tehran University of Medical...

Needle Core Biopsy Should Replace Fine Needle Aspiration Cytology in Breast Lesions Diagnosis

Diagnostic Fine Needle Aspiration in a Case of Riedel’s Thyroiditis

In Riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. Therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. The illustrated case is a 46-yea...
