GENERAL HISTOLOGY

Detailed explanation-1: -Mucoepidermoid carcinomas are the most common type of salivary gland cancer. Most start in the parotid glands. They develop less often in the submandibular glands or in minor salivary glands inside the mouth. These cancers are usually low grade, but can sometimes be intermediate or high grade.

Detailed explanation-2: -Mucoepidermoid carcinoma (MEC) of the salivary gland is believed to arise from pluripotent reserve cells of the excretory ducts that are capable of differentiating into squamous, columnar, and mucous cells.

Detailed explanation-3: -Mucoepidermoid carcinoma (MEC) is malignant, locallyinvasive tumour of the salivary glands 1. It accounts for approximately 35% of all malignancies of the major and minor salivary glands, especially in the parotid gland 1 2. MECs can also occur in the submandibular and minor salivary glands 3.

Detailed explanation-4: -Mucoepidermoid carcinoma (MEC) is known to be a relatively common neoplasm of the major and minor salivary glands that can secondarily involve skin.
