Immunocytochemical typing of primary tumors on fine needle aspiration cytologies of the liver and lymph nodes
BACKGROUND: Difficulties with cytologic diagnoses on FNACs of coin-lesion in the liver and of enlarged lymph nodes can be overcome by the application of immunocytochemical panels applied on smears. The aim of this study was to investigate the performance of different panels of monoclonal antibodies …

Comparison of fine needle aspiration cytology and cell block to formal histology of small subcutaneous mass lesions in children. a prospective study at Red Cross War Memorial Children`s Hospital
Background Fine-needle aspiration cytology (FNAC) has been widely accepted as a safe, cost-effective and accurate tool for the preoperative diagnosis of masses or lesions in adults with over 90% accuracy. The use of FNAC with adjunct Cell block in children is still not widely accepted. Cell block …

Predicting risk of malignancy in patients with indeterminate thyroid nodules
… thyroid ultrasonography and, if needed, a fine-needle aspiration biopsy. Of all fine-needle aspiration biopsies, 15-30% are indeterminate on cytology (5). While only 3% of these nodules are malignant on average, a much higher percentage of nodules are surgically removed in order to rule out …

Evaluation of the P13K pathway and downstream effect in Her-2 positive and negative breast carcinomas
… amplification on archived, Papanicolaou-stained fine needle aspiration (FNA) samples. Tissue blocks from a retrospective series of 93 primary breast carcinoma cases were selected, based on their Her-2 status. Twenty six of these cases received trastuzumab treatment while 67 did not. Expression of …

Discriminating benign from malignant thyroid nodules in real-time using a novel probe with an integrated elastic scattering spectroscopy biopsy syringe
… malignancy. The current standard of diagnosis, fine needle aspiration biopsy (FNAB) yields indeterminate results for approximately 10–25% of biopsies, necessitating thyroidectomy for diagnosis. Elastic scattering spectroscopy (ESS) is a minimally invasive optical biopsy technique that is …

The diagnostic pathway to a surgical lymph node excision biopsy service in a HIV and TB endemic region in a Western Cape Tertiary Institution
… first excision biopsy was 55 days (IQR 22-106). Fine needle aspiration (FNA) cytology of lymphadenopathy was performed in 30/61 (49%) of patients and repeated in a third of these, while smear for AFBs and culture for M. tuberculosis were infrequently performed and GeneXpert MTB/RIF assay on FNA …

An optical smart needle : point-of-care technologies for integrated needle guidance using optical frequency domain ranging
Obtaining accurate needle placement is of critical importance in many medical scenarios. In the setting of fine needle aspiration biopsy (FNAB), manual palpation is often the only cue for determining the optimal position of the needle. As a result, FNAB procedures frequently yield non-diagnostic …
