Lacrimal gland pleomorphic adenoma

From WikiMD's Wellness Encyclopedia

It is a benign, usually encapsulated neoplasm of the lacrimal gland composed of epithelial and mesenchymal cells.

Pathophysiology[edit | edit source]

  • Pleomorphic adenomas are neoplasms that develop in the salivary glands or heterotopic salivary gland tissues.
  • It has been suggested that myoepithelial cells play a major role in the histogenesis of these tumors.
  • In the lacrimal gland, pleomorphic adenomas presumably develop from metaplastic myoepithelial cells.
