Abstract:
Pleomorphic adenoma is the most common benign salivary gland tumour characterized by great histologic diversity. The presence of extensive squamous metaplasia and numerous keratin pearls is mostly uncommon in the microscopic study and can signify a potential pitfall in the histopathological diagnosis Pleomorphic adenoma can show the presence of squamous metaplasia with keratin pearls as a rare finding and is encountered most often in the parotid gland (84%) and 6% in the minor salivary gland. Here we present a case report of a rare histopathological variant of pleomorphic adenoma with exuberant squamous metaplasia and keratin pearl formation of the minor salivary gland in an unusual location.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
