Figure 5: (a) Aspirate reported as squamous cell carcinoma with necrosis (category VI) (Papanicolaou 200×) (b) Follow-up histology revealed Warthin's tumor (H and E 200×). In this case, the dirty background of cyst contents and oncocytic cells in Warthin's tumor was misinterpreted as atypical squamous cells in a background of necrosis. (c) Aspirate showing sheets of monomorphic population of uniform round cells (Category VI) (MGG 200×) (d) Histology reported as small round cell neoplasm (H and E 200×)
