“Away from the lungs”: A case report of extrapulmonary tuberculosis

Abstract

Purpose: To report a case of primary extrapulmonary tuberculosis in immunocompetent. Method: Retrospective observational case report. Results: A 68- year old female presented in a clinic with cervical lymphadenopathy with a suppurative fistula which she has had since April of 2023. During an examination before admission to a clinic on the neck in the right area under the clavicle was a fistula from which sipped a little secretion. In addition, this area was also edematous and painful. In differential diagnosis cat scratch disease has been ruled out. The lab tests showed slightly elevated inflammatory parameters and anemia. The ultrasonography of the neck’s lymph nodes showed multiple lymph nodes which looked like Mts. Indicators of a tumor were negative. Actinomycosis and tularemia were excluded. No oxygenic or anaerobic bacteria was grown in the samples drawn from the nodes. The PCR was positive for DNA of Mycobacterium tuberculosis but acid-fast mycobacteria didn’t grow in samples drawn from fistula. Although the QFT-Plus test was positive and pathomorphology test proved the existence of MTB. Patient was treated with antituberculosis drugs with clinical improvement. Conclusion: Extrapulmonary tuberculosis still occurs in society. It can be difficult to diagnose if there isn’t any source of infection in the lungs.
