Pleomorphic Adenoma:An Overview

The salivary glands are exocrine glands which that produces saliva through ducts. Two types of salivary gland MAJOR and MINOR salivary glands. Salivary glands can be as serous, mucous or seromucous (mixed). The secretion is mediated by parasympathetic stimulation, acetylcholine in the active neurotransmitter and binds to muscarinic receptors in the gland, leading to increase salivation. The salivary glands consist of major and minor glands. The salivary gland tumors are divided into benign and malignant tumors. Pleomorphic adenoma is the most common benign tumor affecting salivary gland. It majorly affects the parotid gland and palate most commonly the hard palate. It develops in both major and minor salivary gland. This article represents a case of pleomorphic adenoma in the minor salivary gland of hard palate.
