Abstract
Pleomorphic adenoma is the most common benign tumour of major or minor salivary glands. Histological diversity is the hallmark of pleomorphic adenoma. Extensive squamous metaplasia with keratin-filled cysts is rarely reported. Here we present two cases of pleomorphic adenoma with exuberant squamous metaplasia and keratin filled cysts formation in a minor salivary gland and discuss its potential diagnostic pitfalls.
