Cytology of Lymph Nodes
نویسنده
چکیده
Enlarged peripheral lymph nodes (lymphadenopathy or lymphadenomegaly) can occur with lymphoid and plasma cell hyperplasia, inflammation, or lymphoid or metastatic neoplasia. Fine-needle aspiration (FNA) cytology of enlarged lymph nodes is relatively non-invasive and inexpensive, and with experience, often provides an accurate diagnosis. However, in some cases, special stains, biopsy, immunophenotyping by flow cytometry, or polymerase chain reaction for antigen receptor rearrangement (PARR) may be helpful for further evaluation.

OBJECTIVE Our goals were to determine the added value of fine-needle aspiration biopsy (FNAB)-thyroglobulin (Tg) measurements over FNAB-cytology alone for diagnosing metastatic nodes, and to determine whether the ultrasound features of lymph nodes can be used to identify lymph nodes that may benefit from FNAB-Tg measurement in patients with papillary thyroid cancer. MATERIALS AND METHODS We r...

Histiocytic necrotizing lymphadenitis (HNL; Kikuchi-Fujimoto disease) is a rare benign disorder. The diagnosis of HNL is established on recognizing the characteristic histologic findings from biopsy of the enlarged lymph nodes. Though diagnosis of HNL by fine-needle aspiration (FNA) was reported, the characteristic fine-needle aspiration cytologic features with conventional cytology and a liqui...

Introduction: Medullary thyroid cancer (MTC) is an uncommon neoplasm originating from parafollicular C cells. Distant metastasis in MTC, such as axillary node involvement, is extremely rare. Case Report: The present study describes a known case of MTC with axillary lymph node metastasis in a 31-year-old woman. In 2010, she underwent total thyroidectomy and right-sided modified radical neck dis...

BACKGROUND During the detection of neck recurrence in patients with Papillary Thyroid Carcinoma (PTC), sometimes it is difficult to distinguish metastatic from inflammatory neck lymph nodes. The measurement of serum thyroglobulin (sTg) under thyroid hormone suppression therapy the presence of serum thyroglobulin antibodies (sAbTg), the diagnostic whole body scan and cytology can give false nega...
