PLEOMORPHIC ADENOMA Meaning and
Definition
-
Pleomorphic adenoma, also known as mixed tumor of the salivary gland, is a benign neoplasm that commonly arises in the major salivary glands, particularly the parotid gland. It is also occasionally found in the minor salivary glands within the oral cavity.
The term "pleomorphic" refers to the presence of diverse cellular components, which is a distinctive feature of this tumor. Pleomorphic adenoma typically consists of a combination of epithelial, myoepithelial, and mesenchymal cells, resulting in a complex histological architecture. The epithelial cells are arranged in a tubular or ductal pattern, while the myoepithelial cells reside within the stroma, forming a network around the epithelial structures. The mesenchymal component includes fibrous, myxoid, or chondroid tissues.
Clinically, pleomorphic adenoma usually presents as a slow-growing, painless mass in the region of the salivary gland. It may cause facial asymmetry or discomfort if it reaches a large size. Although it is generally considered benign, pleomorphic adenoma has the potential to recur after surgical removal if not completely excised. In rare cases, it can undergo malignant transformation into carcinoma ex pleomorphic adenoma, which carries a higher risk of metastasis.
Treatment of pleomorphic adenoma typically involves complete surgical excision. This procedure aims to eliminate the tumor and minimize the chances of recurrence. Regular follow-up and imaging studies are often recommended to monitor for any potential signs of recurrence or malignant transformation.

Etymology of PLEOMORPHIC ADENOMA
The word "pleomorphic adenoma" has its roots in Greek and Latin.
The term "pleomorphic" comes from the Greek words "pleon" meaning "more" or "excessive", and "morphē" meaning "form" or "shape". In medical terminology, it is used to describe a tumor or lesion that exhibits various different forms.
The word "adenoma" is derived from the Greek word "aden", meaning "gland", and the suffix "-oma", which is commonly used to indicate a tumor or mass. Adenoma refers to a benign tumor that arises from glandular tissue.
Therefore, the term "pleomorphic adenoma" describes a benign tumor made up of glandular tissue that exhibits various different forms or shapes. This term is commonly used in the medical field to describe a type of salivary gland tumor.
