Abstract Tuberculosis is a communicable disease with high morbidity and mortality rates in developing countries. The study's primary objective is to compare conventional methods such as acid-fast bacillus (AFB) culture and microscopy with rapid diagnostic methods. The secondary objective is to compare histopathological and microbiological findings in suspected patients with tubercular lymphadenitis. A total of 111 samples (August 2018 to September 2019) of lymph nodes were processed for AFB microscopy, AFB cultures, drug-susceptibility testing (DST), histopathology, and Xpert Mycobacterium Tuberculosis (MTB)/resistance to Rifampin (RIF) assays. Out of 111 lymph node samples, 6 (5.4%) were positive for AFB smear microscopy, 84 (75.6%) were positive for AFB culture, 80 (70.7%) were positive on Gene Xpert, and 102 (91.8%) were indicative of tuberculosis for histopathology studies. Mycobacteria growth indicator tube (MGIT) culture positivity was 84 (75.6%) higher than solid Lowenstein-Jensen (LJ) culture 74 (66.6%). Positive cultures underwent phenotypic DST. Two cases were Multidrug-resistant (MDR) on DST, while three cases were Rifampicin resistant on Gene Xpert. The sensitivity of Genexpert was (62%) against the conventional AFB culture method. The poor performance of conventional lymphadenitis diagnostic methods requires early and accurate diagnostic methodology. Xpert MTB/RIF test can help in the treatment of multidrug-resistant TB cases. Nonetheless, rapid and conventional methods should be used for complete isolation of Mycobacterium tuberculosis.

Breast tuberculosis is an extremely rare entity representing less than 0.1% of all breast disease in developed countries1. Tuberculous infections within the United Kingdom have seen a steady decline with the highest rates present within North West London where infection rates reach 24.8 per 1000002. The presentation can mimic malignancy and lymphatic involvement of the breast both clinically and mammographically, with nodules within the upper outer quadrant, making accurate diagnosis challenging.3 Approximately 30% of breast TB cases present with axillary lymphadenopathy and a recent case series review of approximately 44 cases in London found that the most common presenting feature was a solitary breast lump in 87% of cases.4 We present a case of a patient presenting with primary malignancy and contralateral nodal disease highly suspicious for breast malignancy. Subsequent investigation led to the identification of synchronous localized cancer and tuberculous lymphadenitis. Synchronous presentation is uncommon and recognition and differentiation is vital as axillary lymph node metastasis is the most important factor in the staging of breast carcinoma and determining the subsequent oncological and surgical management.

OBJECTIVE: To investigate the value of contrast-enhanced ultrasound (CEUS) for the diagnosis of cervical tuberculous lymphadenitis (CTL). METHODS: The cohort study included 203 consecutive patients diagnosed with cervical lymph node. Before pathological or laboratory confirmation, all patients underwent CEUS examination, and the imaging findings were analyzed afterward. The diagnostic efficiency of the CEUS imaging findings of CTL was evaluated. RESULTS: Nighty-seven patients of the 203 (47.8%) were pathologically or laboratory confirmed with a CTL diagnosis while the remainder (52.2%) were diagnosed with non-tuberculous lymphadenitis. Regarding the imaging findings of CEUS, it was more common in CTL patients to find a pattern of heterogeneous enhancement inside the lymph nodes relative to non-tuberculous patients [81.44% (79/97) vs 15.09% (16/106), P <  0.01]. The sensitivity of the feature in diagnosis for CTL was 81.44% and the specificity was 84.91%, resepectively. Furthermore, a pattern of peripheral rim-like enhancement had been notable in CTL patients compared with non-tuberculous patients [86.60% (84/97) vs 12.26% (13/106), P <  0.01], associating with a diagnostic sensitivity of 86.60% and a specificity of 87.74% . When it came to the combination of both imaging findings mentioned above, the features were more prominent in CTL patients than compared with non-tuberculous patients [74.23% (72/97) vs 5.66% (6/106), P <  0.01], with a diagnostic sensitivity of 74.23% and a high specificity of 94.34% . Regarding area under curve (AUC) for the ROC analysis, the feature of internal heterogeneous enhancement, peripheral rim-like enhancement, and both features were 0.832, 0.872, and 0.843. CONCLUSIONS: CEUS patterns of heterogeneous enhancement and peripheral rim-like enhancement of lymph nodes are helpful characteristics for the diagnosis of CTL.

Objective: To compare the validity of FNAC & ZN staining in diagnosing tuberculous lymphadenitis taking mycobacterial culture as gold standard. Study Design: Cross sectional study. Place and Duration of Study: Pathology department, Fauji Foundation Hospital Peshawar, from Oct 2019 to Sep 2020. Methodology: This study includes 100 patients with enlarged cervical lymph nodes who presented as outdoor patients. After routine baseline & radiological investigations, FNAC & ZN staining was carried out, followed by mycobacterial culture. Results: FNAC of tuberculous patients was positive in 56 (56%) patients while 24 (24%) patients revealed posi-tive mycobacterial culture. Inpatients with positive culture, 77 (77%) were FNAC positive and 23 (23%) were negative on cytology. Conclusion: Fine needle aspiration is more sensitive & specific test than Ziehl-Neelsen staining.

Kikuchi-Fujimoto disease (KD), also known as histiocytic necrotizing lymphadenitis, is a rare cause of unilateral cervical lymphadenopathy usually described in adolescents and young adults with female preponderance. Clinically patients present with palpable lymphadenopathy, fever, and loss of weight. Hence, it should be differentiated from other causes of lymphadenopathy such as tuberculosis, lymphoma, or malignancy. Although the majority resolve spontaneously without treatment some may require non-steroidal anti-inflammatory drug or steroids. It may also be associated with systemic lupus erythematosus. Hence early detection, prompt diagnosis, and follow-up of the patient are essential in all cases of unilateral cervical lymphadenopathy in young adults. Here, we describe a 22-year old female who presented with unilateral neck swelling and was clinically diagnosed initially as a case of tuberculous lymphadenitis which on biopsy turned out to be KD.

Abstract Background To investigate the value of multimodal ultrasonography in differentiating tuberculosis from other lymphadenopathy. Methods Sixty consecutive patients with superficial lymphadenopathy treated at our hospital from January 2017 to December 2018 were categorized into four types based on the color Doppler ultrasound, five types based on contrast-enhanced ultrasound, and five types based on elastography. Sensitivity and specificity were calculated of all the three imaging, including color Doppler examination, contrast-enhanced ultrasound and one individual multimodal method, for detecting lymph nodes. Results A total of 60 patients were included in the final analysis. Of those, Mycobacterium tuberculosis was positive in 38 patients and negative in 22 patients. Among the 38 patients who were positive for Mycobacterium tuberculosis, of which 23 had a history of pulmonary tuberculosis, accounting for 60.53% of the positive cases, and the remaining patients did not combine lesions of other organs. Among the 60 superficial lymph nodes, 63.3% presented with tuberculous lymphadenitis. The sensitivity, specificity, and accuracy of the color Doppler examination were 73.68%, 68.18%, and 71.67%, respectively. The sensitivity, specificity and accuracy of contrast-enhanced ultrasound were 89.47%, 63.64% and 80.00%, respectively. The sensitivity, specificity and accuracy of the elastography were 63.16%, 63.64% and 63.33%, respectively. The sensitivity, specificity and accuracy of one individual multimodal method were 42.11%, 95.45% and 61.67%, respectively. The sensitivity, specificity and accuracy of all modes combined were 100.00%, 27.27% and 73.33%, respectively. Conclusion Multimodal ultrasonography has high predictive value for the differential diagnosis of superficial tuberculous lymphadenitis.
