It is now universally agreed that examination of bone marrow aspiration material is essential for unravelling many haematological problems. In some cases, however, it is extremely difficult, or even impossible, to obtain specimens, as for example in the myelosclerotic and refractory anaemias. In the former, examination of the bone itself would be of value, and in the latter one would like to se...

INTRODUCTION Cervical lymphadenopathy (LAP) in children is a common clinical diagnostic dilemma. The aim of our study was to analyse ultrasonography, fine needle aspiration biopsy, size and location on the neck to distinguish lymph nodes requiring excision from those that do not. MATERIAL AND METHODS We retrospectively studied 43 cervical lymph nodes that were excised from 43 children aged 0-...

Six cancer resection specimens were thoroughly sectioned and microscopically examined at areas known to have been around 21 gauge fine needle aspiration (FNA) biopsy sites, in an attempt to identify needle tracks. All cases had an interval of not less than 10 days between FNA biopsy and surgery. Foci of tumour were identified histologically in needle tracks from two patients with carcinoma. Thi...

Needle core biopsy (NCB), as part of triple assessment for preoperative evaluation and diagnosis of breast cancer, is now considered as an established, highly accurate method for diagnosing breast cancer that has replaced either fine needle aspiration cytology or excisional biopsy as the initial diagnostic biopsy procedures in many institutions. In addition to its primary role in establishing a...

INTRODUCTION The recently-proposed Bethesda reporting system has offered clinical recommendations for each category of reported thyroid cytology, including repeated fine-needle aspiration (FNA) for non-diagnostic and atypia/follicular lesions of undetermined significance, but there are no sound indications for repeated examination after an initial benign exam. OBJECTIVE To investigate the cli...

PURPOSE To report an experience with fine-needle aspiration biopsy of selected small melanocytic choroidal tumors during the interval from April 13, 1983, through January 19, 2001. METHODS Retrospective descriptive case series report of 34 patients with a small melanocytic choroidal tumor (maximal diameter, < or = 10 mm; thickness, > or = 1.5 mm but < or = 3 mm) evaluated diagnostically by tr...

PURPOSE To access the reliability of fine-needle aspiration biopsy in harvesting a sufficient amount of viable melanoma cells to establish a cell culture and maintain a melanoma cell line from an animal model of uveal melanoma. METHODS For this study, fifteen male New Zealand albino rabbits had their right eye surgically inoculated with uveal melanoma cell line 92.1. The animals were immunosu...

Indications Percutaneous needle biopsy of the lung is indicated for indeterminate pulmonary nodules or masses, particularly those that will likely require chemotherapy or radiation rather than surgery, and in patients with a history of extrapulmonary malignancy. Because targeted therapy has now become an important part of the armamentarium for treatment of lung cancer, percutaneous needle biops...
