A: Typical feature of Warthin-like MEC under low magnification (HEX100); B: Dense lymphocytes (HEX200); C–E: mono-layered, disorganized bi-layered and multilayered oncocytic epithelia in Warthin like-MEC (HEX400); F: Typical bi-layered tumor epithelium in mWTs (HEX400); G: MAML2 fusion positive in Warthin-Like MEC ( × 1000); H: MAML2 negative in mWT ( × 1000).
