Figure 1 shows the cytological features of three consecutive urine samples in Giemsa- and Pap-stained smears. Three consecutive urine samples showed the presence of epithelioid cell granulomas and multinucleated giant cells along with reactive urothelial cells and inflammatory cells [Figure 1a-c]. Special stain for acid-fast bacilli (AFB) was positive [Figure 1d], thereby confirming the diagnosis of tuberculosis.
