Removing an Item from HybridCache

Is there any way to remove an item from HybridCache?
e.g. When the actual file is deleted, you no longer want the thumbnail to be available.
A workaround is to check for the file existence but it's not a very efficient solution.

Start by locating the HybridCache implementation and its supported invalidation or removal entry points; the issue does not name a file or test. Reproduce the case where the source file is deleted, then verify that its thumbnail is no longer available without checking file existence on every request.
