Papillary cystadenoma of the lacrimal caruncle.

The adenoma, which was sharply circumscribed but not encapsulated, consisted in part of radiallyorientated, slender, anastomosing papillary processes clothed by double-layered eosinophilic epithelium (Fig. 2). The basal cells of this epithelium were polygonal and relatively small with round nuclei, while the surface cells were tall and cylindrical in shape with conspicuous cell boundaries, granular eosinophilic cytoplasm, and oval nuclei Iying near the free borders of the cells (Fig. 3).
