Fine-needle aspiration cytomorphology of sebaceous lymphadenoma of the salivary gland.

Sebaceous lymphadenoma (SLA) is a histologic variant of lymphadenoma or sebaceous adenoma of the salivary gland. The fine-needle aspiration (FNA) cytology of SLA has not been well-described. In this report, we reported a case that involved an 81-year-old male with a long-standing left parotid mass and was diagnosed on FNA cytology.

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA): experience of an academic centre in the USA.

Objectives: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has become widely accepted as an effective modality for obtaining tissue for primary diagnosis and staging. We have been using EUS-FNA since July 2001 and herein we summarize our experience over a 5-year period.

Methods: A computer-based search for in-house EUS-FNA was performed in the pathology database from July 2001 to October 2006.

Epithelioid angiosarcoma: a neoplasm with potential diagnostic challenges.

Epithelioid angiosarcomas are extremely rare tumors associated with poor prognosis and early metastases. Its epithelioid cytomorphology and limited vasoformation make it difficult to distinguish from more common malignancies, such as, carcinoma. This can be a potential diagnostic pitfall for the cytopathologist.

Thin core needle biopsy crush preparations in conjunction with fine-needle aspiration for the evaluation of thyroid nodules: a complementary approach.

Background: Fine-needle aspiration (FNA) is widely accepted as the initial test to evaluate thyroid nodules; however, inadequate and suboptimal specimens have been 1 of its limitations. Unsatisfactory rates of 4.1% to 43% have been reported, but suboptimal specimens with adequate epithelial cells and other limiting factors, such as clotting, often are not addressed.
