AbstractBackground:The commonest form of extrapulmonary tuberculosis is tubercular cervical lymphadenitis, or scrofula.Methods and results:A total of 1827 patients with cervical lymphadenopathy who presented to various out-patients clinics of our institution were studied over a three-year period. Eight hundred and ninety-three (48.87 per cent) of these patients had lesions of tubercular origin. The most common observation was unilateral, matted adenopathy in female patients aged between 11 and 20 years and without constitutional symptoms of tuberculosis. Posterior triangle nodes were affected in 43.8 per cent of cases, followed by upper deep cervical nodes in 33.9 per cent. Fine needle aspiration cytology constituted the main diagnostic tool, with a positive yield in 90 per cent of patients. Polymerase chain reaction analysis was performed in 126 patients, with a sensitivity of 63 per cent. Only 18 per cent of patients had associated pulmonary tuberculosis, the rest having isolated involvement of cervical nodes. Medical treatment with anti-tubercular drugs for a period of six months formed the mainstay of treatment and cure. Surgical management was reserved for selected refractory patients.Conclusion:Tubercular cervical lymphadenitis can readily be diagnosed by fine needle aspiration cytology, a simple and cost-effective test. The disease can be cured completely by a short course of anti-tubercular chemotherapy, without surgical intervention.

Introduction: Extrapulmonary tuberculosis is equally important as that of pulmonary tuberculosis. Fine needle aspiration cytology (FNAC) is accurate, cost effective, minimal invasive outpatient procedure and aids in prompt diagnosis of extrapulmonary tuberculosis. Aims: To determine the role of fine needle aspiration cytology for diagnosis of extra pulmonary tuberculosis. Methods: This is a hospital based descriptive study done over a period of one and half year April 2019 to October 2020 at Nepalgunj Medical College Teaching Hospital, Nepalgunj, Nepal. All the 80 patients who were clinically suspected for tuberculosis had undergone fine needle aspiration cytology and diagnosed as tuberculosis in cytology were included in study. Cytological diagnosis was made with microscopic features and positive acid fast bacilli staining. Microscopy showed epithelioid histiocytes, granulomas, multinucleated giant cells, caseous necrosis, neutrophils and mature lymphocytes. Results: Out of 930 cases received, 80 cases were diagnosed as tuberculosis in cytology. 33 cases were diagnosed with acid fast bacilli positive. Rest was diagnosed with cytological features. Among 80 aspirated samples, a portion of purulent specimen was evaluated with Genexpert test in 11 cases for Mycobacterium Tuberculosis detection and rifampicin sensitivity/ resistant. Out of 11 positive patients in Genexpert tests; 10 were rifampicin sensitive and one was rifampicin resistant. Conclusion: Common presentation of extrapulmonary tuberculosis is in lymph nodes with increased frequency in age group of 21 to 30 years. Therefore, lymph nodes in this age group should be prioritized more for investigation of extrapulmonary tuberculosis.

Objective: To evaluate the role of Fine Needle Aspiration Cytology in the preoperative diagnosis of malignancy in parotid and submandibular gland neoplasm. Methods: This cross sectional study on 50 cases was conducted in the Department of Otolaryngology and Head-Neck Surgery of Sir Salimullah Medical College Mitford Hospital and Dhaka Medical College Hospital from January’2009 to June 2010. Results: Fine needle aspiration cytology findings of our all 50 cases were compared with postoperative histopathological reports. Out of the 50 cases, in 36(72%) cases of benign neoplasm and 7(14%) cases of malignant neoplasm, pre-operative FNAC findings and post operative histopathological findings were same. In 7 cases, FNAC and post operative histopathological findings did not matched. These were 2 (4%) false positive and 5 (10%) false negative result.In our study sensitivity of FNAC for reporting malignancy was 58.33%, specificity to rule out malignancy was 94.73% and overall accuracy in detecting malignant tumour was 86%. Positive predictive value and negative value were 77.77% and 87.80% respectively. It can be concluded that fine needle aspiration cytology is a safe, cheap and useful preoperative diagnostic tool in the diagnosis of malignancy in parotid and submandibular gland, but as fine needle aspiration cytology partly depends on operator skill, it may give false negative and false positive result. Conclusion: FNAC is a useful preoperative diagnostic tool for malignant parotid and submandibular glands with high specificity and sensitivity.

The National Public Health Program has established the organized mammography screening in Hungary. The aim of this study was to conduct an audit of “gray zone” smears of the organized mammography screening in comparison with histopathological diagnoses. Methods: Cytology results were rated to C3 atypia probably benign and C4 suspicious of malignancy. Results: 1361 women had aspiration cytology performed from a total of 47,718 mammography non-negative lesions. 105 (7.8%) were diagnosed as C3, whereas 78 (5.7) as C4. Of the 105 patients with C3 diagnosis 61 (58%) patients underwent surgical biopsy. Histology proved malignancy in 20 (32.8%) cases, and benign lesion in 41 (67.2%) cases. All (100%) of the 78 patients with C4 diagnosis had open biopsies; 69 (88.4%) cases were histologically malignant and 9 (11.6%) cases were benign lesions. Conclusion: The auditing results of fine needle aspiration cytology of “gray zone” in organized mammography screening meet the proposed threshold values. Authors conclude that the “gray zone” category in breast cytology is useful and of value if used judiciously. Orv. Hetil., 2011, 152, 292–295.
