Abstract
Pleomorphic adenoma is the most common epithelial neoplasm of lacrimal gland. A clear cell myoepithelial carcinoma arising in the background of pleomorphic adenoma is common in the salivary glands but very rare in the lacrimal glands. We report the case of a 27 year old man whose lacrimal gland pleomorphic adenoma recurred several times over a period of four years and ultimately evolved into a clear cell myoepithelial carcinoma ex pleomorphic adenoma.
