A middle-aged woman developed unilateral, painless proptosis that increased slowly over 1 year. A clinical diagnosis of pleomorphic adenoma of the lacrimal gland was supported by computed tomographic scanning and the tumor was excised. On histological examination the tumor proved to be a benign, myxoid myoepithelioma of spindle-cell type. Although occasionally seen in the salivary glands, to our knowledge, this tumor has not previously been described in the lacrimal gland.
