Fine needle aspiration biopsy cytology of superficial lymph nodes: comparative with histopathology

Fine needle aspiration biopsy cytology was done in 215 lymph nodes involving cervical, submandibular, supraclavicular, axillary and inguinal regions. One hundred and forty of these were diagnosed by histopathology after excisional biopsy or surgery, including 46 cases of metastatic tumor, 57 of lymphoma (46 were non-Hodgkin's lymphoma and 11 were Hodgkin's disease), and 37 of benign lymphadenopathy. Diagnosis of metastatic malignancy was easily made by aspiration biopsy cytology with a total sensitivity of 95.7% (44/46). The diagnosis of lymphoma was less satisfactory with a total sensitivity of 82.5% (47/57). The specificity for diagnosis of benign lymphadenopathy was 97.3% (36/37) with one false positive. The concordance of cell type in aspiration biopsy cytology and histopathology was 75% (33/44) in metastatic malignancy, and 73.5% (28/38) in lymphoma. Typical Reed-Sternberg giant cells were detected in 4 of 11 cases of Hodgkin's disease by aspiration cytology. Out of the 37 cases of benign lymphadenopathy diagnosed by aspiration cytology, 7 were cases of tuberculous lymphadenitis, of which typical Langhans' giant cells were found in 2, and acid fast stain bacilli in 3 cases. There was no complication or needle tract spreading throughout the procedure. We concluded that aspiration biopsy cytology is a simple, safe, reliable, and quick diagnostic method.     

The role of needle aspiration cytology in the differential diagnosis of accessible paediatric tumours

In the period 1985-88, 171 fine needle aspirates from paediatric patients with malignant and non-neoplastic masses were processed and evaluated in the Department of Haematology, Kenyatta National Hospital, Nairobi. Sixty-five needle aspirates had the diagnosis corroborated by histological reports. The rest had relevant clinical and laboratory information to support the cytological diagnosis. The histological diagnosis confirmed cytological diagnosis in 100% for neuroblastoma, 96% for Burkitt's lymphoma, 75% for carcinoma, 68% for sarcoma cases, 53% non-Hodgkin's lymphoma and 50% for Hodgkin's lymphoma. There were no false positives. It is therefore concluded that fine needle aspiration is a useful tool. It may obviate diagnostic surgery, help in planning the course of management of patients and it is diagnostic in Burkitt's lymphoma and neuroblastoma. Fine needle aspiration cytology is an easy, cheap and quick investigation compared to surgical biopsy.     

Fine needle aspiration biopsy cytology in diagnosis of cervical lymphadenopathies

Four hundred and forty-four patients with cervical lymphadenopathies without any consideration for age and sex were subjected to fine needle aspiration biopsy cytology. The results were compared with those of histological sections. In tuberculous lymphadenitis, pyogenic lymphadenitis, Hodgkin's disease and leukaemic infiltration of lymph nodes 100% correct diagnosis was made; it was 98.4% in metastatic carcinoma, 97% in non-specific lymphadenitis and 92.3% in non-Hodgkin lymphoma. An overall 96.2% correct diagnosis was made by fine needle aspiration biopsy cytology technique.     

Fine needle aspiration cytology of thyroid gland and histopathological correlation--revisited

Fine needle aspiration of the thyroid gland, followed by cytological studies and their correlation with histopathological diagnosis have been undertaken to assess the effectiveness of fine needle aspiration cytology in diagnosing disorders of this gland. The cases in which discrepancies had arisen between these two methods of diagnosis have also been reviewed. Out of the total 100 patients studied, 28 were cases of simple colloid goitre, 17 of adenomatoid goitre, 10 of autoimmune thyroiditis ranging from lymphocytic thyroiditis to Hashimoto's thyroiditis, 28 of follicular neoplasia, 10 of papillary carcinoma, one of medullary carcinoma, 2 of anaplastic carcinoma and 4 of cystic lesions of the thyroid gland. Although, fine needle aspiration cytology of the thyroid gland was diagnostic in 75% of cases, it did not correlate with the histopathological diagnosis in the remaining 25% of cases. Possible reasons behind these discrepancies have been discussed.

The experience with fine needle aspiration cytology in the management of palpable breast lumps in the University Hospital Kuala Lumpur

A total of 676 palpable breast lumps seen in the Breast Clinic, University Hospital, Kuala Lumpur from August 1993 to August 1994 were subjected to fine needle aspiration cytology. Fifty-four were reported as inadequate, 501 benign, 95 malignant and 26 suspicious. One hundred and eighty-seven aspirates had histological correlation, while 34 of the malignant aspirates had clinical correlation. The majority of the other 455 patients were followed up for a period of 60 to 72 months without any malignancies becoming apparent. For analysis, only the 221 cases with histological or clinical correlation were included, (the suspicious category was included into the positive group and the inadequate cases were excluded), giving a sensitivity of 91.7%, a specificity of 91.7% and a diagnostic accuracy of 91.7%. Breast cytology was an accurate and rapid method of diagnosis of breast diseases, and in a busy surgical unit with limited operating time, it allowed for the triage of patients with breast complaints in deciding which cases needed early open biopsy. A negative cytology does not exclude the possibility of cancer, as there was a false negative rate of 11%. However by utilising a diagnostic triad of clinical examination, radiological assessment and fine needle aspiration cytology, the risk of missing a malignancy is small.     

Diagnostic evaluation of childhood cervical lymphadenopathy by fine needle aspiration cytology

Lymphadenopathy is an age old affliction of mankind. It is one of the very common presentations in clinical practice. The present study was carried out to evaluate the merits and demerits of fine needle aspiration cytology (FNAC) as a diagnostic procedure in childhood lymphadenopathy in comparison to open surgical biopsy. Altogether 70 children with lymphadenopathy in the age group of up to 12 years were selected for FNAC. Only 38 could be motivated for open surgical biopsy. Out of 38 cases, FNAC was consistent with histopathology in 33 cases, thus giving a diagnostic accuracy or percentage of agreement-86.8%. The diagnostic accuracy of FNAC, sensitivity, specificity, positive predictive values of FNAC in the present study were fairly high ranging from 80%-100%. FNAC gave false positive diagnosis in 13.2% cases and false negative result in 13.2% cases.

Fine needle aspiration biopsy cytology in diagnosis of salivary gland tumours

Fine needle aspiration biopsy cytology of salivary gland tumours was performed in 97 patients. Histological confirmation was available in all cases except 9 cases of sialo-adenitis which responded to antibiotics. Accuracy of cytological diagnosis in exact categorisation of benign and malignant tumours was 93.7% and 91.1% respectively. False negative was 4.1%. The overall accuracy was 95.8%. There was no false positive report. Exact classification of tumour was made in 94.1% cases, ie, 80 out of 85 tumours. No complication was encountered in this procedure.     

Imprint cytology--a cheap, rapid and effective method for diagnosing Helicobacter pylori.

To compare the efficacy of imprint cytology, histology and CLO-test (for biopsy urease) in detecting Helicobacter pylori infection, antral biopsies were taken from 239 patients undergoing upper gastrointestinal endoscopy. Both imprint cytology and histology showed the presence of H. pylori in 215 (90%) patients. The sensitivity and specificity of imprint cytology vis-à-vis histology was noted to be 100%. The CLO-test was performed in 165 patients and was positive in 130 (79%) patients. The sensitivity and specificity of the CLO-test were 89% and 95%, respectively. The median time required for the CLO-test to become positive and for imprint was 60 minutes for each. The sensitivity of the CLO-test was reduced further in patients receiving colloidal bismuth subcitrate. Of the 27 patients receiving the drug the sensitivity of the CLO-test was only 9% after 4 weeks of therapy. However, the specificity was 100%. The sensitivity and specificity of imprint cytology were unaffected by the antimicrobial therapy and after 4 weeks of treatment were still 100%. It is concluded that the CLO-test has a lower sensitivity and specificity for diagnosing H. pylori infection compared to imprint cytology, which had a sensitivity and specificity equal to that of histology. Imprint cytology may be prepared as an adjunct to histology in patients in whom antral biopsies are taken as it offers a relatively quick diagnosis of H. pylori infection, is considerably cheaper than the CLO-test and does not require additional biopsy material.

A review of fine needle aspiration cytology and its scope in Papua New Guinea

Fine needle aspiration cytology has become a very popular investigative procedure in many parts of the world for the diagnosis and management of primary neoplasms. Nevertheless the technique is still not very familiar to most clinicians in Papua New Guinea. Hence this paper provides a brief review of fine needle aspiration biopsy with special emphasis on its methodology, applications and usefulness in a Papua New Guinean setting and on its limitations. It is hoped that such a simple procedure will be used more often in future for tumour diagnosis.     

Evaluation of fine needle aspiration and imprint cytology in the early diagnosis of breast lesions with histopathological correlation

Fifty-one breast lumps were studied by fine needle aspiration cytology (FNAC) and scrape imprint cytology. Of the 51 cases, 28 were malignant and included infiltrating duct carcinoma (22), well differentiated adenocarcinoma (2), mucinous, papillary and lobular carcinoma (one each) and malignant lymphoma (one). Benign lesions were mastitis, fibroadenoma and fibrocystic disease. The diagnostic accuracy of FNAC was 90.2% and that of imprint 94.1% with no false negatives. Two imprint smears and one aspirate designated suspicious were proved to be benign. The combination of FNAC and imprint cytodiagnosis gave a diagnostic accuracy of 96% thus proving their value in the rapid diagnosis of breast lesions.     

A study on thyroid nodules: diagnostic correlation between fine needle aspiration cytology and histopathology

This study evaluated the effectiveness of fine needle aspiration of thyroid nodules to reliably diagnose thyroid malignancy, using histopathology as the 'gold standard'. Out of 126 patients, 106 underwent surgery. The sensitivity, specificity and positive predictive value of fine needle aspiraton cytology to diagnose a papillary carcinoma in this study were 80.7%, 96.5% and 87.0% respectively. The accuracy of fine needle aspiraton cytylogy was 80.9%. Six cases that were benign by fine needle aspiraton cytology were confirmed to have malignant lesion by histopathological examination. High resolution ultrasonography could be useful in these situations for considering surgery.     

Study of salivary gland lesions with fine needle aspiration cytology and histopothology along with immunohistochemistry

Salivary gland swelling is a common and important problem. Acute and chronic sialadenitis, different benign and malignant neoplasms are the common causes which present with salivary gland swelling. Imaging technique is not so helpful in pre-operative diagnosis; microscopical examination is required for diagnosis. Pre-operative core needle biopsy is hazardous and may damage facial nerve, lead to fistula formation or associated with tumour seeding. Fine needle aspiration cytology (FNAC) is however virtually risk-free. The study was done to assess the utility of FNAC and its accuracy and pitfalls with respect to histopathology and advantages of immunohistochemistry. The study was done with 40 cases of salivary gland swelling. After clinical examination, FNAC and histopathological examination along with immunohistochemistry was done and the results were correlated. Out of 40 cases, 25 involved the parotid gland, most common age group affected was 20 - 40 years and male: female ratio was 5: 3. Out of 40 cases 37 cases were cytologically and histopathologically correlated and rest 3 cases were different. Among these 3 cases, 2 were adenoid cystic carcinoma which was cytologically diagnosed as benign neoplasm (monomorphic adenoma). One case of Warthin's tumour was cytologically diagnosed as pleomorphic adenoma. The sensitivity of this study was found to be 71.43%, specificity 100% and accuracy was 93.10%. This study corroborates well with other studies including immunohistochemical findings. p53 expression was found to be related with nature of the neoplasm. FNAC is an important tool for early diagnosis of salivary gland lesions.

Correlation between cytology and histopathology of the salivary glam

Background

Salivary gland swellings can result from tumours, an inflammatory process, or cysts. It can sometimes be difficult to establish whether pathology arises from the salivary gland itself or adjacent structures. Fine needle aspiration cytology (FNAC) is a simple, rapid and safe method to diagnose salivary gland swelling. FNAC has high sensitivity, specificity and accuracy. The aims of this study are to correlate FNAC diagnoses with histopathology and to establish the sensitivity and specificity of FNAC in diagnosis of salivary gland swellings in our institution.

Method

The study was conducted in the department of pathology, Sri Venkateshwara Medical college Hospital and research Centre, Pondicherry, India. Data was collected retrospectively for the time period 2007-2008 and prospectively for that obtained between January 2009 and June 2010. Results of cytologicial assessment were compared with histopathological data where possible to establish sensitivity and specificity of FNAC.

Results

During the study period, 1309 FNAC were undertaken of which 96 FNAC were of salivary gland swellings. Correlation of cytology from FNAC with histopathology tissue was possible in 56 cases. Of the 96 cases for which FNAC data was available, 38.56% were from male and 61.45% were from female patients. The age of the patients ranged from 8 to 69 years. 48.95% cases were benign swellings, 13.54% were malignant, 6.25% were cysts and 31.25% had an inflammatory aetiology. Comparison of FNAC findings with histopathology specimens was available for 56 (58.33%) cases, following which the sensitivity and specificity of cytology were found to be 76.9% and 97.1% respectively.

Conclusion

FNAC is highly sensitive and specific technique for diagnosis of most of the salivary gland swelling. FNAC can be used preoperatively to avoid unnecessary surgery and discomfort associated with open biopsy.     

A 3 year audit of fine needle aspirates from a symptomatic breast clinic.

A total of 2431 fine needle aspirates of symptomatic breast lumps was performed on 2096 patients over the last three years at the weekly head, neck and breast clinic at the Belfast City Hospital Trust. Diagnostic accuracy was achieved within the recommended standards although the "insufficient" rate was high at 31.8%. False negative and positive rates were low and the positive predictive value for malignancy was 99%. Excision biopsy for benign breast disease had decreased by almost a third during this period. Fine needle aspiration cytology is a highly accurate and cost-effective technique for the investigation of symptomatic breast lumps and results in significant savings.
