(a) Unstained FNA smears showing fibrillar and granular parenchyma partially obscured by uneven tegument and subtegument thrown into folds (multiple arrowheads) 100x. (b) FNA smears showing blue nuclei concentrated in the areas where the parenchyma is covered by tegument and subtegument. MGG stain 100x. (c) Other areas reveal bladder wall fragment with blue nuclei. MGG stain 400x.

Before submitting the smears for staining, as a routine protocol unstained smears were evaluated microscopically for cellular adequacy [Figure 1a]. The smears were then stained with May-Grunwald-Giemsa (MGG) and evaluated [Figure 1b and c]. Microscopic examination revealed the bladder wall fragment of cysticercus appearing as a granular, loose fibrillary sheet-like structure, partially obscured by a knobby undulating layer comprising tegument, and subtegument, which could be very well-identified in the unstained smears [Figure 1a]. The folds were better visualized in the unstained preparation, being largely obscured by the numerous nuclei present in the subtegument [Figure 1b].
