Negative images of mycobacteria revisited in rapid on-site evaluation

Rapid on-site evaluation (ROSE) with routine fine-needle aspiration cytology (FNAC) is a simple, economical,
highly accurate tool in the diagnosis of tuberculous lesions. The sample collected can be used for ancillary
studies, i.e., Ziehl–Neelsen stain, Cartridge-based nuclei acid amplification testing (CB-NAAT) and bacterial
culture for confirmation of the tubercular species. We report a case of a 31-year-old male who presented
with left supraclavicular lymphadenopathy. ROSE with FNAC helped in the diagnosis of the patient. FNAC is a
rapid minimally invasive method for the early detection of tubercular lesions and helps in proper treatment.
