case_images: Direct smears of TB-FNA were hypocellular with predominance of cellular debris (a and b) with a few apical fragments of lining cells. These cell fragments demonstrated diagnostic features as seen in zoomed images (arrows) (a1 through a8 and b1 through b8). (a and a1 through a8: Papanicolaou stain; b and b1 through b8: Diff-Quik stain).

case_images: Endoscopic ultrasound-guided fine-needle aspiration (EUSFNA) in the current case was consistent with ciliated lined cystic lesion without malignant cells [Figure 1]. As observed in our case, intact ciliated cells could not be detected; however, there were many cell top fragments of the ciliated cells similar to ciliocytophthoria in Papanicolaou stained and Diff Quik stained direct smears [Figures 1 and 3].
case_images: Unenhanced CT scan of thorax showing a smooth margined right subcarinal soft tissue mass (arrows) measuring 3.9 x 5.4 cm in the posterior mediastinum with no airspace consolidation, pleural effusion or pneumothorax.

case_images: These lesions may remain asymptomatic until they are picked on imaging for screening or otherwise [Figure 2].
case_images: Cell-block of TBFNA aspirate showing degenerated cellular debris with occasional cell fragments showing cilia (arrows). These cell fragments demonstrate diagnostic features as seen in zoomed images (a through f).

case_images: As observed in our case, intact ciliated cells could not be detected; however, there were many cell top fragments of the ciliated cells similar to ciliocytophthoria in Papanicolaou stained and Diff Quik stained direct smears [Figures 1 and 3]. Cell-block also showed similar findings; however, relatively few ciliated cell fragments showed significantly inferior morphology as compared to that seen in cytology preparations [Figure 3].
