title: Langerhans' cells in a pleomorphic adenoma of submandibular salivary gland.
abstract: Large numbers of round and dendritic cells similar to Langerhans' cells of normal epidermis and other epithelia were seen within a pleomorphic adenoma of the submandibular salivary gland. These cells, which were present only in areas of non-cornifying epidermoid metaplasia, exhibited Birbeck granules with isolated terminal vesicles, cytoplasmic microfilaments, microtubules, and a few poorly developed intercellular junctions.
