CONTEXT Pancreatic tuberculosis and peripancreatic tuberculous lymphadenitis are rare, mimicking various pathologies of the pancreas. The coexistence of peri-ampullary malignancy with peripancreatic tuberculous lymphadenitis has not been reported. CASE REPORT We present the case of a young woman who had been operated on with a preoperative diagnosis of peri-ampullary adenocarcinoma in whom a ...

AIMS To determine the specificity of persistent measles virus infection in intestinal samples from Crohn's disease patients using quantitative immunogold electron microscopy. To compare the results with samples from ulcerative colitis, a granulomatous inflammatory control (tuberculous lymphadenitis), and a positive control. METHODS Formalin fixed, paraffin embedded intestinal tissue from pati...

I read with interest the article on the utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in tuberculous intrathoracic lymphadenopathy by Navani et al. EBUS-TBNA has been validated for the assessment of mediastinal nodes in lung cancer and to obtain a diagnosis in (presumed) centrally located lung cancer or sarcoidosis. In addition to a recent report, the s...

BACKGROUND Tuberculous lymphadenitis (TBLN) is the most common form of extrapulmonary tuberculosis. The cytomorphological features of lymph node smears have reduced specificity for the diagnosis of tuberculosis. The diagnosis of TBLN with direct smear microscopy lacks sensitivity due to the limited number of bacilli in lymph node aspirate. Therefore, we aimed to assess whether the concentration...
