Tonsils (at cut-up) are a common ditzel. (WC/Katotomichelakis et al.)

This article collects ditzels, which are, in the context of pathology, little specimens that are typically one or two slides and usually of little interest.[1]

The challenge in ditzels is not falling asleep... so one misses the unexpected (subtle) tumour.
