Abstract
Collagenous spherulosis is a benign breast lesion involving lobular acini and ductules consisting of eosinophilic spherules measuring up to 100 mu in diameter. It is a myoepithelial product. We described similar lesions in salivary gland tumors and a benign lymphoepithelial lesion of the parotid gland.
