Tissue is issue: Not all masses are tumors

Abstract

SummaryBackground:Tuberculosis can disguise itself in any form. Endobronchial tuberculosis usually presents in young adults. Endobronchial tumor-like presentation of tuberculosis (EBTB) is very rare and often mistaken as a malignancy. Diagnosis is usually delayed, as clinical and radiological features are non-specific. Direct implantation of tubercle bacilli into the bronchus, or an contiguous spread, leads to EBTB. Bronchoscopic biopsy and culture are the best modality for diagnosis.Care Reports:Clinical and radiological presentations of all cases were similar and one of them had rib erosion on bone scan. All cases were proven to be tuberculosis by histopathology and culturing mycobacterium tuberculosis. All of them are diagnosed as endobronchial tuberculosis, either histopathology or by culture that grew mycobacterium tuberculosis, and were successfully treated with anti-tuberculous treatment alone, without residual scarring.Conclusions:Tuberculosis should be considered in the differential diagnosis of endobronchial mass lesions in the appropriate clinical setting since this is an uncommon presentation for which invasive procedures are needed to establish the diagnosis. Initially, it was mistaken as a malignancy and there was delay in diagnosis and initiation of treatment. Prompt treatment is crucial to avert residual bronchostenosis.
