Non-imaging-guided fine-needle aspiration of liver lesions: a retrospective study of 279 patients.

AIM:To determine the value of nonimaging-guided (direct) fine-needle aspiration cytology in diagnosing liver lesions.METHODS:Detection by technetium-99m, ultrasound or computed tomographic scanning of the liver was made in 279 patients with 332 aspirations.RESULTS:Based on histologic, cytologic and clinical findings, final liver diagnoses were reached in 265 patients, of whom 171 had malignant and 94 benign liver disease.

Diagnosis of fibroadenoma in breast fine needle aspirates devoid of typical stroma.

Objective: To improve the accuracy of cytologic diagnosis in breast lesion aspirates that are cytologically suggestive of fibroadenoma (FA), exhibiting proliferating epithelial elements and bare nuclei but devoid of the typical stroma.

Study Design: A retrospective study was conducted. All available cases (89) that were aspirated and reported as suggestive of FA between 1981 and 1991 and were later biopsied were studied, and various morphologic criteria were analyzed in each smear.
