Pleomorphic adenoma with extensive cystic degeneration: A rare presentation.

A case of pleomorphic adenoma involving the minor salivary glands of the upper lip, in a 42-year-old man is reported. On gross examination, the tumor presented as a well circumscribed cystic lesion containing whitish cheese like material along with scanty solid areas. Microscopically cystic cavity exhibited keratin, cholesterol clefts and cell debris. A small amount of solid tumor elements was found to be associated with the cyst wall which helped in the confirmation of diagnosis of pleomorphic adenoma. [ABSTRACT FROM AUTHOR]
