Adamantinomatous Craniopharyngioma
Image Description
The presence of nodules of plump anucleated squames - the so-called "wet keratin" is a helpful diagnostic feature of adamantinomatous craniopharyngioma even in the absence of viable epithelium. Keratin nodules may be associated with foreign body giant cell reaction, granulomatous inflammation, dystrophic calcification, and even ossification (shown here).
