      The occurrence of independent oral sebaceous tissue in both its normally situated and aberrant forms has been described. A case has been presented in which the relatively rare incidence of tissue which structurally appeared to resemble sebaceous glands was found in a fairly widespread form in the wall of a dentigerous cyst.
      It is notable that this occurrence probably represents an example of metaplasia involving the change from one specialized epithelial derivative to another, as this dentigerous cyst epithelium must already have taken part in normal tooth formation. While this does not refute Willis's9 idea that glandular metaplasia from simple epidermis does not occur in nonneoplastic conditions, it must still constitute presumptive evidence that metaplastic production of glandular tissue remains a possibility.
