Aim—To assess the feasibility and diagnostic accuracy of endoscopic ultrasound guided fine needle biopsy (EUS-FNAB) in patients with solid pancreatic masses. Methods—Ninety nine consecutive patients with pancreatic masses were studied. Histological findings obtained by EUS-FNAB were compared with the final diagnosis assessed by surgery, biopsy of other tumour site or at postmortem examination, ...

The diagnosis of soft tissues sarcomas by fine-needle aspiration biopsy (FNAB) is controversial and relatively underused. We believe that the lack of acceptance by many clinicians and pathologists may be related to several factors. First, in comparison with other forms of cancer, soft tissue sarcomas are rare, constituting less than 1% of all malignant neoplasms. As a consequence, most patholog...

We have previously shown that cytological diagnosis based on fine-needle aspiration biopsy (FNAB) is a safe and efficient method for the discrimination between benign, primary malignant and metastatic bony lesions. We have now studied metastatic lesions to assess the diagnostic accuracy and to ascertain whether FNAB allows identification of the primary lesion. Between 1990 and 1997, 447 patient...

Fine needle aspiration biopsy (FNAB) is essential in the diagnosis and management of thyroid nodules. In this paper, we report a rare complication, cutaneous sinus formation, after diagnostic FNAB guided by palpation. Sixty-three-year-old female patient was admitted with the complaints of hoarseness and discharge from the anterior neck wall which were present for the last 6 months. The patient ...

Background The outcome of axillary ultrasound (AUS) with fine-needle aspiration biopsy (FNAB) in the diagnostic work-up of primary breast cancer has an impact on therapy decisions. We hypothesize that the accuracy of AUS is modified by nodal metastatic burden and clinico-pathological characteristics. Material and methods The performance of AUS and AUS-guided FNAB for predicting nodal metastases...

Background: Since the first intraocular biopsy performed in 1868 [1] by Hirshberg and experience published by Jackobiec in 1979, fine-needle aspiration biopsy (FNAB) in the eye has been used for several intraocular tumors [2]. In developed countries there is wide experience regarding intraocular FNAB, in contrast to developing countries where this diagnostic tool has been left aside. Aim/Object...

OBJECTIVE To determine histopathologic findings related to the indeterminate or inadequate result of fine-needle aspiration biopsy (FNAB) in papillary thyroid carcinomas (PTCs) and to correlate histopathological findings with ultrasonographic features of tumors. MATERIALS AND METHODS We retrospectively reviewed the medical records of FNAB, histopathologic characteristics, and sonographic find...

OBJECTIVES To determine the usefulness of intraoperative frozen section (FS) examinations in establishing the diagnosis of thyroid cancer in patients undergoing thyroidectomy for nodules with indeterminate cytological features and to determine the cost-effectiveness of FS examinations in this situation. DESIGN Retrospective medical record review. The results of fine-needle aspiration biopsies...

AIM Ultrasonography and fine-needle aspiration biopsy (FNAB) are the mainstays of diagnosing thyroid cancer accurately and reducing the number of diagnostic lobectomies. No benchmark for diagnostic accuracy has been published in the South African context. This single-institution study addresses this deficit. METHODS The oncology, pathology and surgical records of all patients diagnosed with t...
