case_images: Smears were cellular showing intact and degenerated neutrophils, histiocytes, and eosinophils, along with several loose epithelioid cell granulomas, giant cells, and a variable number of lymphoid cells [Figure 1a]. In addition, classic granular, beaded, acid fast bacilli of Mycobacterium tuberculosis were seen [Figure 1b].

case_images: When the ZN stained smears were being screened for the presence of acid fast bacilli, classical hooklets of Echinococcus were noticed [Figure 2a]. Alerted by this discovery, a further search revealed scolices of Echinococcus, which were large ovoid structures [Figure 2b].
