dermoid cyst - ✔✔congenital tumor composed of displaced embryonic tissue (teeth, bone,
|| || || || || || || || || || || ||
cartilage, and hair); typically found in an ovary and usually benign

|| || || || || || || || || || || || ||
lingual concavity of jaw || || ||
not pathological, just a variation on normal anatomy
