Pleomorphic Adenoma
Comments:
Recurrent pleomorphic adenomas usually exhibit multinodular and multifocal growth pattern. They can have variable size and may demonstrate extensive soft tissue involvement in spite of benign histology. The stroma is predominantly myxochondroid in such cases. This image shows a multinodular pleomorphic adenoma with normal salivary gland parenchyma intervening between the main tumor (bottom) and the satellite nodules (top).
