Morphology

epidermoid = epidermis (semi-transparent) = epi + derm + oid

While the connection to 'epidermis' is clear, the specific medical meaning of a tumor is not a standard derivation.

Etymology

Epidermoid comes from the Greek parts epi- 'on', derm- 'skin' and -oid 'like'. So, an epidermoid tumor is a growth made of skin-like cells and can be malignant, meaning it can grow and spread like cancer.
