Percutaneous fine needle biopsy in pediatrics

Pediatric Radiology, 1985
We performed 25 percutaneous fine needle biopsies (PFNB) on pediatric patients during a 3-year period. Of 17 patients with proven malignancies, PFNB was true positive in 16 and false negative in one. In nine patients with benign or inflammatory disorders, there were three true positives and six false negatives.

Transvaginal Fine Needle Aspiration Biopsy

Acta Cytologica, 2001
To assess the role of transvaginal fine needle aspiration biopsy (FNAB) in the evaluation of palpable gynecologic masses.Transvaginal FNABs from 1994 to 1999 were identified from the files of Barnes-Jewish Hospital. Histologic correlation was obtained using the Pathology Department's computer database.

Inaccuracy of Fine Needle Aspiration Biopsy

Ophthalmology, 1985
Fine needle aspiration biopsy (FNAB) of orbital tumors has been recently advocated as a reliable diagnostic modality. An accuracy rate of 92% has been claimed by some authors. This figure remains unproven as most patients have not undergone simultaneous pathologic examination.

Orbital Fine-Needle Aspiration Biopsy

American Journal of Ophthalmology, 1985
Fine-needle aspiration was used as a primary orbital diagnostic technique in 156 patients. A 20-mm syringe, a 22-gauge, 3.75-cm needle, and a plastic pistol grip were used. Local anesthetic was not necessary. When the needle is in the lesion, small to-and-fro movements with a minimum of angulation are helpful.

Fine-needle aspiration biopsy of the mediastinum

The American Journal of Medicine, 1986
Fine-needle aspiration is a useful technique to identify neoplasms of many sites, such as breast, thyroid, and lung. Thirty-two mediastinum aspirates from 29 patients were reviewed. Five aspirates yielded insufficient material. Five aspirates were of benign lesions. Four aspirates were suggestive of but not diagnostic of malignancy.

Fine Needle Aspiration Biopsy in Lymphoma

Radiologic Clinics of North America, 1990
Patients with lymphoma undergo excisional biopsy of an affected lymph node for initial classification of their disease because accurate classification depends on the histologic characteristics of the neoplasm. However, fine needle aspiration cytology has a role in the management of lymphoma patients, particularly in those with recurrent or residual ...

Pediatric Fine-Needle Aspiration Biopsy

American Journal of Clinical Pathology, 1991
A total of 135 fine-needle aspiration (FNA) biopsies from varying sites were performed in 123 children (mean, 10.5 years; range, one day to 18 years) over a five-year period. One hundred thirty (96.3%) biopsy specimens were satisfactory for evaluation. Seventy-nine cases were nonneoplastic (60.8%); among these cases, a specific diagnosis of infectious ...

Fine Needle Aspiration Biopsy of the Pancreas

Scandinavian Journal of Gastroenterology, 1976
Fine needle aspiration biopsy from the pancreas was carried out peroperatively in 60 patients. A suspicion of malignancy due to a palpaple mass in the pancreas was raised in 45 cases and confirmed by cytology in 27 cases. Of the remaining 18 cases in which malignancy was suspected, the majority were caused by penetrating gastroduodenal ulcers or ...
